program, and then other sections such as biscuit, runner, gate, and overflow were also modeled in the order. Figure 1 shows an example of mold modeling to manufacturer clutch housing parts in application of the high-pressure die casting method. Five gates were used, and the thickness was 3 mm. Figure 2 shows the 3D image of a mold in actual size modeled by using Pro/ENGINEER. The total weight of the mold weighed in 3D modeling was about 12.52 ton, the fixed mold about 3.83 ton, and the moving mold about 8.69 ton, respectively. Two slide cores were operated with five tunnel pins. Specially applied was a chill block with no vacuum device. To prevent dispersion toward the chill block upon casting, a vent insert was added between the moving core and chill block as a shock-observing device to decelerate melting. A slipper was added around the four guide pins to handle problems that might occur to the mold. To prevent the slide core from being pushed toward the hydraulic cylinder upon closing the mold, a retrograding-preventive plate was installed on the fixed mold base. A distributor in contact with the sleeve was designed in a plate type. The hydraulic cylinder applied to

铸造模拟软件MAGMA操作教程

2－6、排序
图（2_13）
说明：如图（2_13）中选择，若选择move before（移动方式）则inlet会放在gating1前面。
参照Overlay原理进行排序。一般砂模（sandm)放在最前面，铸件（cast）放在最后。
2－7、设置点
图（2_14）
流迹点选择在inlet下，２０个点左右。热点选择在入水口相连的铸件内，选择热点时步骤２替换为THERMO。
2－3、载入．stl档
接上动把.stl档存在CMD文件夹下后，在创建专案的界面（图（2_1））按下preprocess 键，进入载档界面.见图（2_9）
图（2_9）
图（2_10）
载入顺序如上图所标的序号和箭头指向。注意在载前一定要确定群组属性正确。当载入一物件
后，欲载入同样的群组另一物件。则需要在以上图中的３操作之前按下MAT ID +键（上图虚线框标示）。
4_7 应力设置(stress simulation options)
图（4_7）
4_8 运算
5、后处理
６、Info
五、数据库（DATABASE）
设置完成之后，选择图（2_9）中的SAVE ALL AS1存档。然后离开界面进行下一动作。
３、切网格
图（3_1）
自动切割一般设置３百万的网格数。对于很薄的gating和ingate需要进行单独细切，视切出网格的质量而定。我们用细切的网格数自动切割时，若网格质量比细切的要好，则需要检查一下.Stl档有没有错误。
在建构实体时有一些区域重合。如图（2_7），ingate连接cast和gating，其和两者都有交接的部分。我们希望各部分独立不干涉，保证分析的精确。利用overlay原理切割重合区域。如图（2_8）排在前面的ingate被排在后面的gating和cast切割。在载入．stl档后需利用此原理进行排序。

optimazation of foundry process

Application of a Multi Objective Genetic Algorithm and a Neural Network to the optimisation of foundry processes.G.Meneghetti *, V. Pediroda**, C. Poloni ***Engin Soft Trading Srl, Italy** Dipartiento di Energetica, Università di Trieste, ItalyAbstractAim of the work was the analysis and the optimisation of a ductile iron casting using the Frontier software. Five geometrical and technological variables were chosen in order to maximise three design objectives. The calculations were performed using the software MAGMASOFT, devoted to the simulation of foundry processes based on fluid-dynamics, thermal and metallurgical theoretical approaches. Results are critically discussed by comparing the traditional and the optimised solution.1. IntroductionA very promising field for computer simulation techniques is certainly given by the foundry industry. The possibility of reliably estimating both the fluid-dynamics, thermal and microstructural evolution of castings (from the pouring of the molten alloy into the mould till the complete solidification) and the final properties are very interesting. In fact if the final microstructure and then the mechanical properties of a casting can be predicted by numerical simulation, the a-priori optimisation of the process parameters (whose number is usually high) can be carried out by exploring different technological solutions with significant improvements in the quality of the product, managing of human and economical resources and time-savings.This approach is extremely new in foundry and in this work an exploratory project aimed at the process optimisation of an industrial ductile iron casting will be presented.2. The simulation of foundry processes and foundamental equationsFrom a theoretical point of view, a foundry process can be considered as the sequence of various events [1-4]:-the filling of a cavity by means of a molten alloy, as described by fluid-dynamics laws (Navier-Stokes equation),-the solidification and cooling of the alloy, according to the heat transfer laws (Fourier equation),-the solid state transformations, related to the thermodynamics and the kinetics.A full understanding of the whole foundry process requires an investigation throughout all these three phenomena. However under some hypotheses (regular filling of the mould cavity, homogeneous temperature distribution at the end of filling, etc.) the analyses of the solidification and the solid state transformation only can lead to reliable estimation of the final microstructure and of the properties of the casting.The accuracy in simulating the solidification process depends mainly on:- the use of proper thermophysical properties of the materials involved in the process, taking into account their change with temperature,- the correct definition of the starting and boundary conditions, with particular regard to the heat transfer coefficients.From a numerical point of view, the investigation of the solidification process could be carried out by means of a pure heat flow calculation described by Fourier’s law of unsteady heat conduction :∂∂ρ∂∂λ∂∂t ()x [x C T T p j j=However a more correct evaluation requires to incorporate the additional heat transport by convective movement of mass due to temperature dependent shrinkage of the solidifying mush.Doing that temperature-dependent density functions are needed, so that the shrinkage can be calculated basing on the actual temperature loss. The total metal shrinkage within one time interval will lead to a corresponding metal volume flowing from the feeder into the casting passing through the feeder-neck. The actual temperature distribution in the feeder neck can be calculated on the basis of the following equation :∂∂ρ∂∂ρ∂∂λ∂∂t ()x (u )x [x ]C T C T T S p j p j j j+=+where the second term on the left hand side of the equation is the convective term while the first one on the right hand side is the conductive term. S denotes the additional internal heat source. The additional heat transport by convective movement of mass means that feeding may last much longer than being calculated by heat flow based uniquely on conduction.Anyway, when the feeder-neck freezes to a certain temperature, the feeding mechanism locks.Therefore the solidification of any other portion of the cast, now insulated, will take place independently from one another and the feed metal required during solidification will come from the remaining liquid. The final volume shrinkage will result in a certain porosity, which typically will be located at the hot spots.From the point of view of the real industrial interest, the above phenomena and the related equations can be approached only numerically: in fact complex 3D geometries have to be taken into account, as well as manufacturing parameters ensuring compliance with temperature-dependent thermophysical properties of the materials, production and process parameters. Finite elements,finite differences, control volumes or a combination of these are typical methods implemented in the software packages [2-3].The final result of the simulation is the knowledge of the actual feeding conditions, which is the basis for correctly design the size of feeders. It must be recalled that this knowledge-based approach is often by-passed by the use of empirical rules and in most cases the optimisation of the feeder size is not really performed (so that the feeders are simply oversized) or it is carried out by means of expensive in-field trial-and-correction procedures.The analyses were performed by using the MAGMASOFT ® software, specifically devoted to the simulation of foundry processes, based on fluid-dynamics, thermal and metallurgical theoretical approaches. In particular MAGMASOFT has a module, named MAGMAIron, devoted to the simulation of mould filling, casting solidification, solid state transformation, with the related mechanical properties (such as hardness, tensile strength and Young Modulus) of cast irons [8]3. Optimisation toolFormally, the optimisation problem addressed can be stated as follows.Minimise: F j (X ) , j=1,nWith respect to:X Subject to c X i mi (;,≥=01X (F ),......X (F ),X (F n 21Where X is the design variables vector, F i(X) are the objectives, and c i(X) are the constraints. FRONTIER’s optimisation methods are based on Genetic Algorithms (GA) and hill climbing methods. These allow the user to combine the efficient local convergence of traditional hill climbers, with the strengths of GA’s, which are their robustness to noise, discontinuities and multimodal characteristic, their ability to address multiple objectives cases directly, and their suitability for parallelisation.GA GENERAL STRUCTURE. A GA has the following stages:1.initialise a population of candidate designs and evaluate them, then2.create a new population by selecting some individuals which reproduce or mutate, and evaluatethis new populationStage 2 is repeated until terminationGA MECHANISMS. Design variables are encoded into chromosomes by means of integer number lists. Though there is an inherent accuracy limitation in using integer values, this is not significant since accuracy can easily be refined using classical optimisation techniques. The initial selection of candidates is important especially when evaluations are so expensive that not many can be afforded in the total optimisation. Initialisation can be done in FRONTIER either by reading a user-defined set, or by random choice, or by using a Sobol algorithm [9] to generate a uniformly distributed quasirandom sequence. The optimisation can also be restarted from a previous population.The critical operators governing GA performance are selection, crossover reproduction, and reproduction by mutation.Four selection operators are provided, all based on the concept of Pareto dominance. They are; (1) Local Geographic Selection; (2) Pareto Tournament Selection; (3) Pareto Tournament Directional Selection; and (4) Local Pareto Selection. The user can choose from these though (4) is recommended for use with either type of crossover, and (2) to generate the proportion of the population which is sent to the next generation unmodified.Most emphasis in FRONTIER is on use of directional crossover, which makes use of detected direction of improvement, and has some parallels with the Nelder & Mead Simplex algorithm. Classical two-point crossover algorithm are also provided.Mutation is carried out when chosen, by randomly selecting a design variable to mutate, then randomly assigning a value from the set of all possibilities.In all cases, GA probabilities can be selected by the user, in place of recommended defaults, if desired. All the algorithm are described in more detail in [10].OPERATIONAL USER CHOICE. Traditional GA’s generate a complete new population of designs from an existing set, at each generation. This can be done in FRONTIER using its MOGA algorithm. An alternative strategy is to use steady state reproduction via a MOGASTD algorithm. In this case, only a few individuals are replaced at each generation. This strategy is more likely to retain best individuals. The FRONTIER algorithm removes any duplicates generated. Population size are under the user’s control. FRONTIER case study work has usually used population from 16 to 64, due to the computational expense of the design evaluations.Classical hill climbers can be chosen by the user not only the refine GA solution. They can be adopted from the start of the optimisation, if the user can formulate his problem suitably, and if he is confident that the condition are appropriate.Returning to the problem of expansive design evaluation, many research have made use of response surface. These interpolate a set of computed design evaluation. The surface can then be used to provide objective functions which are much faster to evaluate. Interpolation of nonlinear functions in many variables, using polynomial or spline functions, becomes rapidly intractable however. FRONTIER provides a response surface option based on use of a neural net, with two nodal planes.Tests have shown this to be an extremely effective strategy when closely combined with the GA to provide a continuous update to the neural net.FITNESS AND CONSTRAINTS HANDLING. The objective values themselves are used as fitness values. Optionally, the user can supply weights to combine these into a single quantity. Constraints are normally used to compute a penalty decrementing the fitness. Alternatively, the combined constraint penalty can be nominated as an extra objective to be minimised.PARALLELISATION OF GA. The multithreading features of Java have been used to parallelise FRONTIER’s GA’s. The same code is usable in a parallel or sequential environment, thus enhancing portability. Multithreading is used to facilitate concurrent design evaluations, with analyses executed in parallel as far as possible, on the user’s available computational resources.DECISION SUPPORT. Even where there are a number of conflicting objectives to consider, we are likely to went to choose only one design. The Pareto boundary set of designs provides candidates for the final choice. In order to proceed further, the designer needs to focus on the comparative importance of the individual objectives. The role of decision support in FRONTIER is to help him to do this, by moving to a single composite objective which combines the original objectives in a way which accurately reflect his preferences.LOCAL UTILITY APPROACH. A wide range of methods has been tried for multiple criteria decision making . The main FRONTIER technique used is the Local Utility Approach (LUTA)[11]. This avoids asking the designer to directly weight the objectives relative to each other (though he can if he wishes), but rather asks him to consider some of the designs which have already been evaluated, and state which he prefers, without needing to give reasons. The algorithm then proceeds in two stages. First it decides if the preferences give are consistent in themselves, and guides the designer to change them if they are not. Then, it proposes a ‘common currency’ objectives measure, termed a utility, this being the sum of a set of piecewise linear utility functions, one for each individual objective. The preference information which the designer has provided can then be stated as a set of inequality relations between the utilities of designs. The algorithm uses the feasible region formed by these constraints to calculate the most typical composite utility function which is consistent with the designer’s preferences.This LUTA technique can be invoked after accumulating a comprehensive set of Pareto boundary designs as a result of a number of optimisation iterations. The advantage of the latter approach is that the focusing of attention on the part of the Pareto boundary which is of most interest can result in considerable computational saving, by avoiding computing information on the whole boundary. In practice so far in FRONTIER, we have generally used the LUTA technique after a set number of design evaluations, after which the utility function for a local hill climber to rapidly refine a solution.4. Object of the study and adopted optimisation procedureThe component investigated is a textile machine guide, for which both mechanical and integrity requirements are prescribed. Such requirements are satisfied, respectively, by reaching proper hardness values and by minimising the porosity content. Furthermore, from the industrial point of view, it is fundamental to maximise the process yield, lowering the feeder size.The chemical composition of the ductile iron is the following :C Si Mn P S Cu Sn Ni Cr Mg3.55 2.770.130.0380.00370.0480.0450.0170.0300.035The liquidus and solidus temperatures are 1155°C and 1120°C respectively. The thermo-physical properties of the material (thermal conductivity, density, specific heat, viscosity) are already implemented into the MAGMASOFT Materials Database.The GA optimisation process was performed starting from a configuration of the casting system which is already the result of the foundry practise optimisation.Only the solidification process was taken into account for the simulation, since it was considered to be more affected by the technological variables selected. Therefore the temperature of the cast at the beginning of the solidification process was set as a constant. Moreover the gating system was neglected in the simulation since its influence on the heat flow involved in the solidification process was thought to be negligible. As a consequence the numerical model considers only the cast, the feeder and the feeder-neck (see Fig. 1, referred to the starting casting system). The adopted mesh was chosen in such a way to balance the accuracy and the calculation time. As a consequence a number of metal cells ranging from 9000 to 12000 (resulting in a total number of cells approximately equal to 200000) was obtained in any analysed model.Five technological variables governing the solidification process have been taken into account and the respective ranges of possible variation were defined:1.temperature of the cast at the beginning of the solidification process , 1300 °C <T init.< 1380°C;2.heat transfer coefficients (HTC) between cast and sand mould , 400 W/m2K <HTC< 1200W/m2K;3.feeder height, 80 mm <H f< 180 mm4.feeder diameter, 30 mm<D f < 80 mm5.section area of the feeder-neck, 175 mm2 <A n< 490 mm2.These variables were considered to be representative of the foundry technology and significant in order to optimise the following design objectives :1.Hardness of the material in a particular portion of the cast2.casting weight (i.e. raw cast + feeder + feeder-neck)3.porosityAim of the analysis was to maximise the hardness and to minimise the total casting weight and the porosity. No constraints were defined for this analysis.Generally speaking, the optimisation procedure should be performed running one MAGMA simulation for each generated individual. That implies the possibility to assign all the input parameters and start the analysis via command files. Similarly the output files should be available in the form of ascii files from which the output parameters can be extracted. However at this stage a complete open interface between MAGMASOFT and Frontier is not still available. As a consequence another solution was adopted. First of all 64 analyses were performed in order to get sufficient information in all the variable domain. After that a interpolation algorithm was used to build a response surface model basing on a Neural Network, “trained” on the available results. It has been verified that the approximation reached is lower than 1% for all the available set of solutions with the exception of one point only where the approximation is slightly lower than 5%. After that the response surface model was used in the next optimisation procedure to calculate the design objectives. In such a way further time-expensive work needed to run one MAGMASOFT interactive session for each simulation was avoided.Concerning the Genetic Algorithm a mix between a classical and directional cross-over was used. The first population was created in a deterministic way.5. Results and discussionThe first optimisation task was done for 4 generations with 16 individuals for each generation. Since a complete simulation required about 20 minutes of CPU time on a workstation HP C200, the total CPU time resulted in about 21 hours and 20 minutes. Figs. 3, 4 and 5 report the obtained solutions. In particular from the tables it can be noted that the hardness values increase as we move from the first to the fourth generation, while the weights decrease. Not the same for the porosity, whose values seems to be less stable to converge towards an optimum solution: in fact the same range between the minimum and the maximum value is maintained both in the first and in the last generation. Moreover Fig. 2 illustrates the strong correlation between the casting weight and the hardness: such correlation is due to the particular geometry of the casting under examination and to the position where the hardness value was determined. Anyway the dependency between these two variables is favourable, the hardness increasing as the casting weight decreases, due to the changed cooling conditions. Figs 3 and 4 show that the other variables are not correlated to each other. From all these three figures it can be noted that the optimisation algorithm tends to calculate a greater number of solutions in a specific area of the design objectives plane, where the optimum solution can be expected to be located.As mentioned before the second optimisation step was performed using an approximation function consisting of three independent Neural Networks (one for each design objective) to fit the results obtained from the first optimisation procedure. Then to explore more extensively the variables domain, an optimisation task was done for 8 generation with 16 individuals for each generation.Figs. 5, 6 and 7 report the obtained solutions. By comparing this set of figures with the corresponding previous one (figs. 2, 3 and 4), it can be noted that the GA could reach better solutions, located at the top-right side area of each diagram. Since the raw casting weight was equal to about 2.5 kg and not influenced by any of the chosen variables, the casting weight resulted to be never lower than about 3 kg.All these design objectives were further processed to obtain the results in the form of Pareto Frontier. The Pareto set is reported in table 1, consisting of 11 non-dominated solutions. A direct comparison among them allowed for identifying three solutions (indicated with number 4, 7 and 8 in table 1) which seemed to reach the best compromise among the three objectives.These solutions were checked by running three MAGMAIron simulations. The comparison between the design objectives as predicted by the response surface model and as calculated by MAGMAIron is reported in table 2. It can be noted that the hardness values are predicted with good approximation by the Neural Network, while the porosity values do not match satisfactorily those calculated by MAGMAIron. Anyway the optimum set of variables (4, 7 and 8) reported in table 1 together with the objectives calculated by MAGMAIron were compared with the set of variables corresponding to the present foundry practise. The results, reported in table 3, suggest to decrease the heat transfer coefficient and the feeder size and to increase the feeder-neck section, in order to reach the objectives. The initial temperature instead is already very near to the optimised value.Finally Fig. 8 compares the sizes of the feeders and highlights the bigger feeder now adopted with respect to that of the optimised solution.6. ConclusionsFrontier was applied to MAGMASOFT code enabling the numerical simulation of mould filling and solidification of castings. On the other hand till now it was not possible to interface Frontier with MAGMASOFT since this software does not accept command files to input design parameters. As a consequence an initial optimisation procedure running MOGA for 4 generations with 16 individuals for each generation was performed and a Neural Network was built through the available design objectives. A second optimisation task running Frontier for 8 generations with 16 individuals for each generation was performed. Some design objectives belonging to the Pareto setwere then checked running MAGMASOFT simulations. The following conclusions could be drawn :•In this application the hardness could be increased from 207 HB up to 220 HB and the casting weight reduced from 4.53 kg to 3.11 kg with a slight increase in porosity from 1.27% to 1.80%.•The approximation that could be reached with the Neural Network is probably limited by the small number of available “training points” considering that five design variables were treated. Infact one of the three design objectives was not predicted satisfactorily, as compared with the solution obtained by MAGMASOFT.References[1]M.C.

岩浆岩的主要岩石类型(国外英文资料)

Magma Rock: The Primary Types of Igneous Rocks (Based on InternationalEnglish Resources)When delving into the fascinating world of geology, one cannot overlook the significance of igneous rocks, which originate from the solidification of molten rock, or magma. This document presents an overview of the primary types of igneous rocks, as described in international English resources. Let's explore these rock varieties that have shaped our planet's surface over millions of years.1. Intrusive Igneous RocksIntrusive igneous rocks form when magma cools and solidifies beneath the Earth's surface. The slow cooling process allows for the formation of large crystals, giving these rocks a coarsegrained texture. Some of the main types of intrusive igneous rocks include:Diorite: Diorite is a mediumtodark gray rock with aphanitic texture, consisting of plagioclase feldspar, biotite, hornblende, and pyroxene.2. Extrusive Igneous RocksExtrusive igneous rocks form when magma reaches theEarth's surface and cools rapidly, resulting in finegrainedor glassy textures. These rocks are often associated with volcanic activity. Key types of extrusive igneous rocks include:Understanding the primary types of igneous rocks is crucial for geologists, as these rocks provide valuable insights into the Earth's geological history and the processes that have shaped our planet.Magma Rock: The Primary Types of Igneous Rocks (Based on International English Resources)continuing our exploration of the diverse world of igneous rocks.3. Textures and StructuresThe texture of an igneous rock is a reflection of the conditions under which it formed. International English resources often highlight the following textures:Aphanitic Texture: This texture is found in extrusive rocks where the crystals are too small to be seen with the naked eye. The rapid cooling prevents the growth of large crystals.Phaneritic Texture: Intrusive rocks exhibit this coarsegrained texture, where individual mineral crystals are visible to the naked eye due to the slow cooling underground.4. Chemical CompositionFelsic Rocks: These rocks are rich in silica and have a light color. They include rocks like granite and rhyolite. Felsic rocks have a high viscosity, which means they tend to erupt explosively.Mafic Rocks: Lower in silica content and often darker in color, mafic rocks such as basalt and gabbro have a lower viscosity. They tend to flow more easily and produce less explosive volcanic activity.Ultramafic Rocks: These are rocks with very low silica content and high magnesium and iron content. They are rare on the Earth's surface but are found in the mantle.5. Occurrence and UsesIgneous rocks are found all over the world and have a variety of uses, which are often detailed in international English resources:Construction: Many intrusive igneous rocks, like granite and diorite, are used in construction due to their durability and aesthetic appeal.Landscaping: Basalt is frequently used in landscaping, both as decorative stone and in the production of crushed stone for pathways.Industrial Applications: Certain igneous rocks, such as olivinerich peridotite, are used in the production of metal refining and as a source of magnesium.6. The Rock CycleIgneous rocks play a pivotal role in the rock cycle, which is the process which rocks are created, changed, and destroyed over time. International English resources often describe how:These rocks can be buried and subjected to heat and pressure, leading to the formation of metamorphic rocks.Metamorphic rocks can melt and return to the mantle as magma, starting the cycle anew.Magma Rock: The Primary Types of Igneous Rocks (Based on International English Resources)as we delve deeper into the geological narrative woven igneous rocks.7. Mineral Content and IdentificationThe mineral content of igneous rocks is a key factor in their identification and classification. International English resources often emphasize the following minerals: Mica: Common in many igneous rocks, mica is known for its flaky, sheetlike structure and can be black, white, or green.8. Volcanic Activity and Igneous Rock FormationThe formation of igneous rocks is inextricably linked to volcanic activity, a topic extensively covered in international English literature:Volcanic Eruptions: During eruptions, magma is expelled onto the Earth's surface, where it cools quickly to form extrusive igneous rocks.Plutons: When magma remains below the surface, it cools slowly over time, forming intrusive bodies known as plutons, which can later be exposed erosion.9. Environmental ImpactSoil Formation: The weathering of igneous rocks is a crucial step in the formation of soil, which supports plant life and agricultural activity.10. Geochronology: The Key to Earth's HistoryIgneous rocks are often used to date geological events, a field known as geochronology, which is vital for understanding Earth's history:Radiometric Dating: Certain minerals within igneous rocks, such as zircon, contain radioactive isotopes that can be used to determine the age of the rock.Isotope Ratios: By analyzing the ratios of different isotopes in igneous rocks, scientists can infer past environmental conditions and the timing of geological events.11. Future Research DirectionsAs our knowledge of igneous rocks continues to expand, international English resources suggest several avenues for future research:Planetary Geology: The study of igneous rocks on other planets and moons can provide insights into the geological processes that have shaped our solar system.In wrapping up our exploration of igneous rocks, it's clear that they are more than just stones; they are time capsules that hold the secrets of our planet's past and the keys to understanding its future. Through the lens of international English resources, we see a rich tapestry of scientific discovery and geological intrigue that continues to unfold.Magma Rock: Major Types of Igneous Rocks (Based on International English Resources)1. Granite2. DioriteDiorite is a mediumgrained igneous rock that contains plagioclase feldspar, biotite, hornblende, and sometimes quartz. Its color ranges from dark gray to black. Diorite is often associated with granite and is used in construction similar to granite.3. Andesite4. Basalt5. Gabbro6. PeridotitePeridotite is an ultramafic igneous rock that is rich in olivine and pyroxene. It is often green in color due to the presence of olivine. Peridotite is found in the Earth's mantle and is associated with diamond and platinum deposits.These major types of igneous rocks offer a glimpse into the dynamic processes occurring beneath the Earth's surface. Each rock type has its unique characteristics and plays a vital role in shaping our planet's geology.Magma Rock: Major Types of Igneous Rocks (Based on International English Resources)7. Rhyolite8. Anorthosite9. KimberliteKimberlite is a unique type of ultramafic rock that is best known as the primary host for diamonds. It is characterized its distinctive "pipe" structure and is often rich in olivine and pyroxene. Kimberlite eruptions areviolent and fast, creating carrotshaped geological formations that can be a source of significant economic interest.10. PegmatitePegmatite is an extremely coarsegrained igneous rock that forms during the final stages of magma crystallization. It can contain exceptionally large crystals, sometimes measuring several meters in length. Pegmatites are often associatedwith granite and can be a source of rare minerals, including lithium, tantalum, and cesium.11. KomatiiteKomatiite is an ancient and now rare type of ultramafic volcanic rock that dates back to the Archean Eon. It is high in magnesium and iron, and its formation is associated with high temperatures in the Earth's mantle. Komatiites are important for understanding early Earth's geological history.12. TuffEach of these igneous rock types tells a story about the conditions under which they were formed, the processes that have shaped them, and the secrets they hold about the Earth's past. From the towering mountains capped with granite to the dark, fertile soils derived from basaltic lava flows, igneous rocks are a fundamental part of the planet's geological tapestry. Their study not only enriches our understanding of the Earth's history but also provides valuable insights into the resources we harness and the landscapes we cherish.Magma Rock: Major Types of Igneous Rocks (Based on International English Resources)13. ObsidianObsidian, often referred to as volcanic glass, is an extrusive igneous rock with a vitreous luster and a smooth, glassy texture. It forms when lava cools rapidly, preventingthe growth of crystals. Obsidian is usually dark in color, ranging from dark brown to black, and has been used ancient cultures for tool making and as a material for decorative objects.14. Pumice15. ScoriaScoria is a volcanic rock with a vesicular texture,similar to pumice, but it is typically darker in color and has a more crystalline structure. It is often used as a landscaping material and in the construction of drainage beds due to its porosity and durability.16. PicritePicrite is an ultramafic rock that is rich in olivine and low in silica. It is often dark green to black and can be mistaken for basalt. Picrites are significant as they provide clues about the geochemical processes occurring in the mantle.17. Aphanitic Igneous RocksAphanitic rocks are finegrained igneous rocks that cool quickly on or near the Earth's surface, preventing the growth of large crystals. This category includes rocks like basalt and andesite, which, due to their rapid cooling, have a microscopic or very finegrained texture that is not easily visible to the naked eye.18. Phaneritic Igneous RocksPhaneritic rocks are coarsegrained igneous rocks that form when magma cools slowly beneath the Earth's surface, allowing crystals to grow larger. This group includes rocks like gabbro and granite, which can be appreciated for their visible mineral grains and often beautiful patterns.19. HornfelsThe study of these varied igneous rocks not only provides a window into the dynamic geological processes that have shaped our planet over millions of years but also serves as a foundation for understanding the distribution of natural resources and the environmental impacts of volcanic activity. Each rock type, with its unique history and characteristics, contributes to the rich tapestry of Earth's geological story.。

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xx本科毕业论文外文资料翻译系别： xxx专业： xxx姓名： xxx学号： xxx1 区域成矿背景概述塔木铅锌矿床位于阿克陶县塔木村北约5 km,大地构造位置为西昆仑造山带与塔里木板块的交接部位[1],属库斯拉甫-他龙铅锌(铜)成矿带的一部分。

本区前震旦纪末期陆壳裂解形成塔里木板块、西昆仑地体、帕米尔板块等。

加里东期塔里木板块沿库地北断裂(俯冲带)往南西向西昆仑地体俯冲,形成昆中岩浆弧;两者于志留纪末期拼贴为一体[2]。

加里东期花岗质岩浆侵入时代的变化趋势佐证了这一观点[3]。

晚古生代时受古特提斯裂解作用的影响,俯冲带迁移到康西瓦断裂带附近,板块俯冲方向由南西往北东,西昆仑中带成为晚古生代岩浆弧(即昆中多期岩浆弧)[4],库斯拉甫-他龙地区正处于弧后位置,在板块俯冲的影响下发展为晚古生代弧后裂谷(即奥依塔格-库尔良裂陷槽)。

随着古特提斯洋的消亡,库斯拉甫-他龙晚古生代裂谷盆地于二叠纪末期闭合。

三叠纪时期本区处于隆起剥蚀状态,缺失沉积。

侏罗纪为山间盆地相与间夹沼泽相沉积。

至白垩纪末与早第三纪早期,因受新特提斯裂谷化作用遭受一次海侵,形成一套浅海至湖相的沉积岩系。

在喜马拉雅期造山运动的作用下,新特提斯洋闭合,青藏高原崛起,盆山构造急剧分野,引起本区西昆仑前缘大规模的逆冲推覆和走滑,形成铁克力克推覆体等构造,奠定了现今的构造格局。

因此,库斯拉甫-他龙铅锌(铜)成矿带所处的大地构造位置为晚古生代弧后裂谷盆地)))具陆壳基底的奥依塔格-库尔良裂陷槽,晚古生代的裂谷沉积作用、海西末期和喜马拉雅期的强烈构造作用为本区大范围、高强度的铅锌(铜)成矿创造了有利的构造条件[5]。

塔木MVT型铅锌矿区及外围主要出露上泥盆统、石炭系、侏罗系与白垩系)第三系地层,褶皱构造为科克然达坂复式向斜东翼的塔木向斜,区域断裂有克孜勒陶-库斯拉甫北北西向走滑断裂系与北西向昆北逆冲推覆断裂系。

勇者斗恶龙9(DQ9)武器资料

殊效果相当好用，而其中的银河之剑，攻击力更是本作所有武器之首。

而“DQ最强剑”的隼剑更不用提，托DQ9中攻击力上升系统的福，本作中的隼剑更是头顶青天，堪称高力量职业居家旅行、杀魔王抢宝物必备，但这个2次攻击的效果也是有限制的，仅限于普通攻击、屠龙斩、金属斩、隼斩（4次伤害，动作还是2次）、脱力攻击、断刃（以上两个是战士的技能“勇敢”中的特技，特殊效果有两次判定）、斗魂搏击、无心攻击（以上两个是战斗大师的技能“斗魂”中的特技）、以及AI战斗时所作出的动作，另外，在使用游人的技能“曲艺”中的特技——玩球杀法时，攻击次数由6~8次变成7~9次。

有战士和僧侣这两个职业可以装备它——尽管大多数枪都要靠买以外的方法获得；尽管枪比其他任何武器都要来得更容易被盾格挡住。

不过只要有心，在游戏早期就能拥有不错的枪。

而最强的四把枪看似终于能将枪容易被格挡的坏毛病丢掉，实则只有在普通攻击时才有这种恩惠，枪技能没辙，让人大跌眼镜。

短剑一般是作为魔法师等力量偏弱角色的武器给人印象的。

杀手耳环可以看做是弱化版的隼剑（其实看英文名就知道了……），其效果和隼剑一样，局限性和隼剑也基本一样——仅限于普通攻击、剧毒短剑（中毒判定有两次）、昆虫杀手、死神狩猎、刺客袭击（即死判定有两次）、睡神狩猎、脱力攻击、断刃（以上两个是战士的技能“勇敢”中的特技，特殊效果有两次判定）、斗魂搏击、无心攻击（以上两个是战斗大师的技能“斗魂”中的特技）、以及AI战斗时所作出的动作，同样的，在使用游人的技能“曲艺”中的特技——玩球杀法时，攻击次数由6~8次变成7~9次。

最后四把“回合第一个攻击”的武器特效的局限性也差不多：该特效局限于剧毒短剑、昆虫杀手、死神狩猎、刺客袭击、睡神狩猎、脱力攻击、断刃、斗魂搏击、无心攻击、以及AI战斗时所作出的动作。

另外，当队伍中有两个或者两个以上的人同时装备最后这四把武器时，攻击顺序按照速度来判定。

是用来杀伤敌人的，而在于其各种各样的特殊效果。
