试验室汇报材料范文

试验室汇报材料范文英文回答：Introduction:In this lab report, I will discuss the experiment that I conducted in the laboratory. The purpose of the experiment was to investigate the effects of temperature on the rate of enzyme activity. Enzymes are biological catalysts that speed up chemical reactions in living organisms. The rate of enzyme activity is influenced by various factors, including temperature. By studying the effects of temperature on enzyme activity, we can better understand the optimal conditions for enzyme function.Methodology:To conduct the experiment, I first prepared a solution of the enzyme and substrate. I then set up a series of test tubes, each containing the same amount of the enzyme-substrate solution. The test tubes were placed in a water bath at different tem peratures, ranging from 10°C to 50°C.I used a colorimeter to measure the absorbance of the solution at regular intervals over a period of time. The absorbance values were recorded and used to calculate the rate of enzyme activity.Results:The results of the experiment showed that the rate of enzyme activity increased with temperature up to a certain point, and then started to decrease. At lower temperatures, the enzyme activity was relatively low, as the enzymes were not able to catalyze the reaction effectively. As the temperature increased, the enzyme activity also increased, reaching its peak at around 37°C. However, beyond this temperature, the enzyme activity started to decrease, asthe high temperature caused denaturation of the enzyme.Discussion:The observed trend in the results can be explained bythe effect of temperature on enzyme structure and function. At low temperatures, the enzymes have low kinetic energy and are not able to collide with the substrate molecules frequently enough to catalyze the reaction. As the temperature increases, the kinetic energy of the enzymes and substrate molecules also increases, leading to more frequent collisions and increased enzyme activity. However, at high temperatures, the increased kinetic energy causes the enzyme to vibrate and disrupt its three-dimensional structure. This denaturation of the enzyme leads to a decrease in enzyme activity.Conclusion:In conclusion, the experiment demonstrated that the rate of enzyme activity is influenced by temperature. The optimal temperature for enzyme activity was found to be around 37°C, while both lower and higher temperatures resulted in decreased enzyme activity. These findings have important implications in various fields, such as medicine and biotechnology, where the understanding of enzyme function is crucial. By optimizing the temperatureconditions, we can enhance the efficiency of enzyme-catalyzed reactions and improve various processes in industries and healthcare.中文回答：引言：在这份实验报告中，我将讨论我在实验室中进行的实验。

英语测试学报告Testing Report

Testing ReportPart 1 Introduction:This testing paper was conducted by Class2, junior students in Anqing Teachers College .There’re 39 people in Class2 and all of us wrote this items for Class1.In Class2, 41 have participated in this exam, for our instructor Mr.Xiong acted as the supervisor and the other student ask for leave ,among which are 35 girls and 6 boys.There are 100 items in our test and all the items are multiple choices, which were searched online. We choose all the items from TEM4 and College English Test. Besides, the items were all about grammar and vocabularies. Every member of our class found 20 items, then handed to the head of the dormitory and picked 50 items. Finally, our study monitor collected 100 items. After the exam, the study monitor and other students calculated the scores by using Excel and then put it into our public mail box, which can be downloaded by all the classmates.Part 2 Data presentation and analysisChart of scoresSN101112131415161718 Score757572717171716867SN192021222324252627 Score676666666565646462SN282930313233343536 Score616059585857575755Frequency distributionFrom the table of scores, we can see directly the distribution of different scores and their frequency as well as central tendency and variability. Most scores occur in the group 69-60, secondly in the group 79-70.And 4 students’ scores spread over 0~40, only one student get the score of 90.So the majority of the students’ English level is concentrated, the difference between them is a little high.Basic data12.61≈From this chart we can clearly see the relationships between each item. The ideal test paper is that the mean and the median are the same, and the mode is higher than the two, but this one is not very good. Firstly, the difference between the highest scoreand the lowest score is 52, which is much high. Secondly, this paper shows a negative skewed, in which the mode is the biggest and the mean is the lowest. Finally, the standard deviation is 12.61, which is also high. So we can see that the English ability of these students is vastly different from each other.Facility valueDistribution of FVThese charts and diagrams show the Facility Value about the test. There are 39 items between 0.3<FV<0.7（39%）,9 items≦0.3(9%) and 52items≦0.7(52%).Furthermore, the average of the Facility Value is about 0.66, which shows that the test is relative proper for the students. But in details, there are much more easy items in the test and the percentage of that is more than a half, and only a fewer difficult items. So in this way it is not a very appropriate paper. And the FV of first item is 0.15, it may be a lot difficult. The distribution of this test is not reasonable. The earlier ones should appear first and then the more difficult ones.Item DiscriminationDistribution of IDThis form shows the item discrimination of the paper: 24%( ID≧0.4)of the items are acceptable, but 76％(ID<0.4)should be changed or deleted. Some items even have no ID at all, such as 14, 26. These items may over our levels. As a result, the paper is not good to separate good students from poor ones, such as 1, 7, 11...Reliability①6360v=1591411N==--∑（X-M)②()10015966(10066)=0.8675433581(1)(1001159ttnv M n Mrn v--⨯-⨯-==--⨯）In order to get these statistics, I use the method of Kuder Richardson to calculate the reliability. Reliability refers to the consistency of the scores from a test. First of all, I calculate the mean score and use the score diminish the mean score, and use the first formula to calculate the variance. And at last I use the second formula to calculate the reliability, whose score is 0.8675433581.So I think the paper is not appropriate in some degree, and from the Facility Value and Item Discrimination, it is also not a suitable one for the students.Part 3 ConclusionAfter several days of working hard and sitting in front of the computer, the testing paper is finally finished. At first, I must show my thankfulness to Mr. Xiong to giveme the valuable opportunity to do the huge project. This experience really let me make a big progress. Secondly, although the test paper is done by each of the classmate and all of us try our best to search items in the internet. But generally speaking that it is not a good paper. It may be a little lower of the students’ level. And there are some most difficulty items and little easier items in this text. But, in some degree, this paper also can select the good students. To be honest, as English major students, we must improve our abilities after doing this test in daily life. Thirdly, I know the difficulty of being a teacher after doing this testing report, but it is also a challenge for me. If I want to achieve my dream to be a good teacher, I must make every effort to come over these difficulties. Finally, this is also a precious experience for me and I know more about how to evaluate a test paper by scientific research with the tedious data processing.。

实验报告的英文

Abstract:The objective of this experiment was to determine the effect ofdifferent light intensities on the growth rate of a particular plant species, specifically the Gerbera daisy (Gerbera jamesonii). This study aimed to investigate how varying light exposure impacts plant height, leaf area, and overall health. The experiment was conducted over a period of four weeks, with three different light intensity levels being tested: low, medium, and high. The results were analyzed to draw conclusions about the optimal light conditions for the growth of Gerbera daisies.Introduction:Plants require light for photosynthesis, the process by which they convert light energy into chemical energy to fuel their growth. The intensity of light, along with other factors such as duration and quality, can significantly affect plant growth and development. This experiment was designed to explore the relationship between light intensity and the growth of Gerbera daisies, a popular flowering plant known for its vibrant colors and attractive blooms.Materials and Methods:1. Materials:- Gerbera daisy seeds- Seedling trays- Potting soil- Grow lights- Light intensity meters- Ruler- Leaf area calipers- pH test strips- Watering can2. Procedure:- Gerbera daisy seeds were sown in three identical seedling traysfilled with the same potting soil.- The trays were placed under three different light intensity levels: low (200 lux), medium (500 lux), and high (1000 lux).- The light intensity was maintained by using grow lights that were adjusted to the desired levels using light intensity meters.- The seedlings were watered daily to maintain consistent soil moisture levels.- The pH of the soil was checked weekly and adjusted if necessary using pH test strips.- Plant height and leaf area were measured weekly using a ruler and leaf area calipers, respectively.- The overall health of the plants was observed and recorded weekly.Results:1. Plant Height:- The plants under the high light intensity showed the highest growth rate, with an average height of 15 cm after four weeks.- The plants under the medium light intensity grew to an average height of 12 cm.- The plants under the low light intensity were the shortest, with an average height of 9 cm.2. Leaf Area:- The plants under the high light intensity had the largest leaf area, with an average of 45 cm².- The plants under the medium light intensity had a leaf area of 38 cm².- The plants under the low light intensity had the smallest leaf area, with an average of 30 cm².3. Overall Health:- The plants under the high light intensity appeared to be the healthiest, with vibrant green leaves and no signs of stress.- The plants under the medium light intensity also showed good health, with slightly less vibrant leaves.- The plants under the low light intensity showed signs of stress, including yellowing leaves and slower growth.Discussion:The results of this experiment indicate that light intensity plays a crucial role in the growth of Gerbera daisies. The plants exposed tohigh light intensity showed the highest growth rate and leaf area, suggesting that this light level is optimal for their development. Conversely, the plants under low light intensity exhibited slower growth and signs of stress, which may be attributed to insufficient energy for photosynthesis.The findings of this study are consistent with previous research thathas shown the positive effects of high light intensity on plant growth. However, it is important to note that excessive light can also be detrimental to plants, leading to heat stress and photoinhibition. Therefore, it is crucial to find the balance between light intensity and other environmental factors to ensure optimal plant growth.Conclusion:In conclusion, this experiment has demonstrated that light intensity significantly affects the growth of Gerbera daisies. The results suggest that a high light intensity of 1000 lux is the most conducive to the growth of these plants, resulting in increased height, leaf area, andoverall health. These findings can be applied to horticultural practices to optimize plant growth conditions and improve the productivity of Gerbera daisy cultivation.References:- Smith, J., & Jones, K. (2018).

实验的报告（集锦15篇）

实验的报告实验的报告(集锦15篇)随着个人的素质不断提高，我们使用报告的情况越来越多，报告中涉及到专业性术语要解释清楚。

你所见过的报告是什么样的呢？以下是小编整理的实验的报告，希望对大家有所帮助。

实验的报告1希奇，真希奇！语文课上，老师拿来一盆清水，一份报纸和一个玻璃瓶，竟然告诉我们这一节课要做一个趣味实验。

接下来就是我对这场实验的描述。

时间：20xx年6月9日。

地点：六（2）班教室实验材料：一盆清水、一份报纸和一个玻璃瓶。

实验准备：先撕下一张报纸，揉成团后塞进瓶中。

实验前的猜测老师拿着塞了报纸的玻璃瓶，问道：“如果我将这瓶子瓶口朝下浸入水中，你们说这瓶子中的报纸会不会湿？”一时间，教室里炸开了锅。

大家七嘴八舌地猜测着。

老师示意大家安静下来，举手发言。

操冰清第一个被老师点到名。

只见她从容不迫地站起身来，胸有成竹地说道：“我认为将玻璃瓶倒着放入水中，报纸不会湿。

”老师笑着点点头，让操冰清坐下，又叫已经举手好久的胡鸿杰回答。

胡鸿杰迫不及待地站起来，当我认为他要开始长篇大论时，他却仅仅从口中吐出了几个字：“我认为报纸会湿。

”然而，他的观点得到了大多数同学的认可，近半的人都纷纷附和。

老师拍了拍手让大家静下来，让坐在胡鸿杰后排的厉凯锋发言。

“我以前试过将一个空瓶子倒着放进水里。

”厉凯锋自信地说道：“瓶子被放下去的时候会有一股阻力，而拿起来时有吸力，水是不会进入瓶子里的，所以报纸也不会湿。

”他说得有理有据，令不少人信服，我也暗自点头。

老师让站起来发言的同学坐下，总结说：“现在出现了两种观点，一种是报纸会湿，另一种是不会湿，接下来，就让老师来做一做这个实验。

”老师示范实验过程老师开始做实验“为了公正，你们可以验证一下，这个瓶口是没有被封住的。

”老师说着，让前排的同学摸了摸瓶口。

“现在已经证实瓶口是开着的，那么我就把瓶子放下去了。

”说着，老师把瓶子放入水中，瓶口向下，“过一分钟我再把瓶子拿起来。

”过了一会儿，老师应我们的要求将瓶子从水中取出。

三、实验分析东元工厂现有返工工艺概括：BBF背板组件，如碎片、气泡、杂物等不良组件经层压加热15分钟后，高温下将组件背板扒掉，此过程用力过大，玻璃发生形变，造成组件网状、线形隐裂；待组件冷却后，盖一层EVA和背板，经返工层压工艺（360s-60s-60s-360s）温度139℃层压后，切边后流入装框工序。

隐裂情况TPT背板组件，返工直接将碎片、气泡位置切掉，换好电池片，直接盖EVA和背板，经同样的层压工艺后，流入装框工序。

现有的返工工艺就BBF背板组件，返工过程隐裂覆盖率可达100%，无A0组件，A级品95%，B级品5%。

均达不到公司品质标准，工艺通过改善提出不扒皮直接盖背板的返工方式。

因BBF背板主要成分为聚偏氟乙烯（pvdf），氟塑料本身以颗粒形式分散在基础树脂中，相互不接触；因此，需要测试组件背板之间的剥离强度、交联度、抗湿热性、抗老化性，组件的隐裂测试和外观标准。

到目前为止，各项实验测试工作已步入尾声。

四、实验过程1.将10pcs背板不良组件送入返工工序，员工拆掉边框后做EL测试，组件均无可见性隐裂。

测试结果报告

Testing report徐维红(4) (020111165)Part 1IntroductionThe testing subjects are 41 juniors (39 girls and 2 boys), who major in the English Department of Anqing Teachers College. The testing paper we use to test class5 containing 100 single choice questions, each marks one point. I chose 20 items from TEM-4 on the Internet, and then I emailed them to our dorm leader with answers attached. Each dorm provided 50 items to the study monitor-me. There are 8 dorms in our class, so I chose 100 items from 400 items. It was really a very huge job. First, I did all the items. Then I selected some typical items out and arranged them according to their types and their ease. After finishing choosing 100 items, I printed it out and arranged five other class leaders to have a test. During the test, they found some problems in some items, and some items are too difficult. So I changed some of them to improve the quality of the paper. On Nov.18, we took the test in the classroom205, Building B. It took about 43 minutes to finish the test. After the test, I marked the papers with other 8 class leaders. After a whole term learn of the English Language Testing, the designing and analyzing the paper provide me a good opportunity to apply all I have learned into practice.Part 2Data presentation and analysisIn this part, I will report the test scores and provide some statistics to analyze several factors concerning with assessing the paper. Such as mean score, median, mode, range, standard deviation, test reliability, item difficulty level , item discrimination and the distribution of the options.1.The score of the subjectsI rearrange the scores from the highest one to the lowest one, so we can knowclearly how the scores distribute.76816 6125 5434 4686717 5826 5335 4596618 5727 5236 45From the table of scores, we can clearly see each student’s score, and the rank of the whole class.2.Frequency distribution of scoresFrequency distribution is a mean to process the raw scores which are in disorder.And it is also the first step when we analyze testing results. Next, I would like show you the frequency distribution of the test.Table2 the frequency distributionScore Group Frequency Score Group Frequency 79-75 ///3 59-55 //////674-70 //2 54-50///////////1071-65 //////6 49-45 /////564-60 /////5 44-40 ////4the frequency distribution口79-75口74-70□ 71-65□ 64-60Frequency口59-55口54-50口49-45口44-40From the table2, we can see directly the distribution of different scores and their frequency as well as central tendency and variability. The majority of students, scores(25 students) are under 60 , and most of them are in the group of 54-50.While only 3 students, scores in the range of 79-75.3. Measures of central tendency and measures of variabilityTable3 the central tendency and variabilityCentral tendency Figure Variability Figure Mean Score56.976 The Highest Score79From table3, we can see that the range is 39. It shows the gap between the highest and lowest marks is too large. And the standard deviation is 10.556.It is larger than 10, so the variability of the scores is large, the English level of students in the class varies considerably. But mean score (56.976)>median (55) =mode (55), it shows in a positive way. This kind of distribution means that most students ’ scores are lower than mean score. It is good for choosing excellent students, but as a speed test, it is not good for stimulating students, learning interest.4.Split half reliabilityFor this, first calculate the rank order correlation between the odd and the even halvesof the test, and then use the Spearman Brown correction formula. Next, I will use this method to calculate the reliability of the paper.Table4r = reliabilityZ N=41Z d2= 4166.56Z d2 1 - 6 x 4166.5 249981rho = 1 -[ -------- --- ]=[ ]=1 - [ -------- ] = 1 - 0.36 = 0.64 N (N 2 -1) 41x1680 68880The correlation between the two halves of the test is 0.64, so r = 0.64r = ^h^ = 2 X 0.64= 0.78 So r = 0.78tt 1 + r 1 + 0.64 tthhThe split half reliability index is 0.78.A perfect reliability coefficient of good vocabulary, structure and reading tests is 0.90 to0.99.But the reliability of the paper is 0.78, so it is not high enough. It means almost 60% students, ranks have not changed, but 40% students, ranks have changed.5.Facility valueFacility value is a measure of the ease of a test item. It is the proportion of thestudents who answered the item correctly. The following table will show you the facility value of the paper.Table5facility valueWe know that the standard facility value is between 0.3 and 0.7. But from the above table, we can clearly see that only 58% items meet the standard. That means there are 12% items are too difficult and 30% items are easier. Totally, 88% items are within the standard or easier. So the facility value of the paper is proper. Now, I will show you some typical items, facility value and the items.The 75th item, its facility value is 0.It means on one was right. The item is the most difficult one. Let us see the item:75、Of course, talking about something which affects them personally is C motivating forstudents.B. correctlyC. currentlyD. eminentlyThe right option is C-currently which means at the present time. The word is within the requirement of TEM-4 and the other three options are learned before. Why is there on one right The reason is that it is hard to understand the sentence without relevant knowledge about educational psychology. So no one was right.6. Item discriminationIt refers to the ability of a test item to separate good students from poor ones in a particular aspect of the foreign language. Now, I will show you the item discrimination of the paper.Table7 item discriminationDiscrimination IndexNumbers PercentageDI<0 8 8%DI=0 13 13%0<DI<0.4 62 62%DI N0.41717% The items which are equivalent to or higher than 0.4 can be acceptable. But from the abovetable, we can see that among the 100 items, there are only 17 items can be acceptable. It means the other 83 items should be changed or deleted. Why the FV of most items are normal but the discrimination index are unacceptable? Next, I will analyze it.Table8 the discrimination index of some typical itemsItem No.Facility Value(FV)RT RBDiscriminationIndex53 0.39 3 5 -0.15464 0.63 8 8 0A. chieflyNote: RT二right numbers in the top groupRB二right numbers in the bottom groupFor example:53、一Does Alan like hamburgers?—Yes. So much D that he eats them almost every day.A. forB. asC. toD. soAnalysis: The facility value of the item is proper (0.39), but the discrimination index is -0.154.Why? In the top group, there are 3 students right but in bottom group 5 students are right. Is there something wrong with the item? After analyzing the item, I find the item is not difficult. The structure“so much so that...” have been learned before. So the possible reason is that the students of top group do not pay enough attention to some basic structure.The other example:64、The harder the shrub is to grow, C .A. the higher price it isB. the higher price it would haveC. the higher the price isD. the higher is the priceAnalysis: The facility value of the item is proper (0.63), but the discrimination index is 0.There are 8 students right both in the top group and in the bottom group. The reason is that both the top students and the bottom students learned the structure well. So the item has no discrimination index. I suggest the item should be changed.From these analyses, we can know that the facility value of some items is proper, but the discrimination index is unacceptable. So we cannot judge the quality of an item just from the facility value.7. The distribution of the optionsOptionsAccording to our experience, the options of most tests seems like distributing on C, and moststudents tend to choose C as their answer when they are not sure which one is right. But in this paper, the distribution of options is different from traditional one. It is a kind of innovation.Part 3 ConclusionsFrom the data and analysis, we may draw a conclusion as follows:In general, the paper is not very good. The mean score, median and mode are not the same. Although they distribute in a positive way, as a speed test, it is not good for stimulating students, learning motivation. Besides, the item discrimination is not high; some items have no discrimination index and some items ' discrimination index act in a negative way. Most items should be changed or deleted. What ,s more, the reliability of the paper is 0.78, so it is not high enough. It means almost 60% students , ranks have not changed, but 40% students ' ranks have changed. But in terms of the facility value, 88% items are within the standard or easier. So the facility value of the paper is proper.Besides, I have learned a lot from this course. First, I have known how to judge the quality of a paper and how to calculate relevant data. Second, after selecting items and designing the paper, I have gained some experience about how to select items and how to design a paper. Third, the most important thing I have learned from this course is that whenever you do something, you should be patient and careful. Therefore, I must thank Mr.Xiong for giving me the chance to improve myself. Thank you!^^ 5 0 5 0sreamnNOptions□ A □ B。
