国际十进分类法 UDC及查询
国际十进分类法UDC及查询国际十进分类法UDC《国际十进分类法》(UDC)是世界上规模最大、用户最多、影响最广泛的一部文献资料分类法。
自1899-1905年比利时学者奥特勒和拉封丹共同主编、出版UDC法文第一版以来,现已有20多种语言的各种详略版本。
近百年来,UDC已被世界上几十个国家的10多万个图书馆和情报机构采用。
UDC 目前已成为名符其实的国际通用文献分类法。

柴油发电机组设计手册及行业标准四篇
柴油发电机组设计手册及行业标准四篇篇一:柴油发电机组设计手册一、概述1、本设计手册范围本手册适用于XX(XX)柴油发电机组的安装指南。
在设计和安装柴油发电机组之前,请仔细阅读本手册,详细了解设备情况,只有正确的安装并维护保养设备,才能够保证设备安全有效地运转。
机组运行的故障和意外伤害,多数情况是由于没有遵循设备的安装规范而产生的。
本手册的内容包括机组的选型、基础设计、排风和冷却系统、燃油系统、启动系统、电气系统、噪声控制系统、机房尺寸建议及相关法律法规。
本手册内容编入环保安装,符合国家环境法规要求。
2、安装规范业主在购买、安装XX柴油发电机组前应该注意:2.1 机房建筑应获得批准;2.2机组的功率符合环保要求;2.3对以下方面做出控制,符合相应规范:机房燃油符合消防规范(GB50045-95)机组噪声符合《环境噪声标准》(GB3096-20XX)尾气排放符合《大气污染物排放标准》(DB44-27-20XX)电气安装符合《国家电气安装规范》(GB50055-93/JGT16-92)二、发电机组选型1、概述柴油发电机组一般分为主用和备用。
为了缓解全国用电紧张状况,一些工厂及生产企业将柴油发电机组作为主用电源,以应对电力系统停电或错峰供电等电力供应紧张时的电力需求。
在电力资源相对充足的情况下柴油发电机组一般作为备用电源。
2、机组功率选择2.1功率的定义和匹配XX发电机组功率定义遵循ISO8528标准,柴油发电机组的输出功率受周围环境的限制,XX发电机组标定的功率是在“标准状态”下的输出功率。
40℃,大气压力海拔1000m以下。
标准状态:环境温度 0~常用功率(额定功率):发电机组在此标定功率下可连续运行12小时,并允许有1小时的10%过载能力。
备用功率:发电机组年运行时间不大于500小时;备用功率连续运行时间不超过1小时;年平功率不超过标定功率的70%;无过载能力。
90%负载下运行,发电机组磨损及发电机组功率匹配:发电机组在额定功率80%~燃油的经济性将达到最优状态,获得最佳的经济特性。

scw620标准
scw620标准SCW620是指Society of Computer Applications in Weaving 620这个标准。
SCW620标准是由织造行业的计算机应用协会(Society of Computer Applications in Weaving)制定的。
该标准的目的是提供一种通用的框架,以帮助织造行业采用计算机技术进行生产和管理。
该标准涵盖了各个方面的织造工艺,从设计到成品品质控制。
SCW620标准的主要内容包括以下几个方面:1. 数据库管理:SCW620标准规定了织造行业中常见的数据库管理系统的标准结构和数据模型。
这样可以确保不同的系统之间能够互相兼容和交换数据,提高生产效率和信息流畅度。
2. 设备控制:标准详细定义了设备控制模块的功能和接口,使得不同的设备之间可以进行通信和协作。
这样可以实现自动化控制和智能化管理,提高生产效率和资源利用率。
3. 工艺参数:标准规定了常见的织造工艺参数的表示方法和标准单位。
这样可以确保不同的工艺参数之间可以无缝地转换和比较,提高工艺管理的精度和准确性。
4. 可视化界面:标准规定了可视化界面的设计原则和技术要求。
这样可以确保不同的织造管理系统具有统一的视觉风格和用户体验,提高用户的工作效率和满意度。
5. 数据安全:标准定义了数据安全管理的基本要求和措施。
这样可以确保织造行业的关键数据得到合理的保护和管理,防止数据泄露和丢失。
SCW620标准的实施对于织造行业具有重要的意义。
首先,它可以帮助织造企业提高生产效率和管理水平。
通过合理地配置和管理计算机系统,企业可以减少人工操作和浪费,提高生产效率和产品质量。
其次,标准可以提高行业内部的信息共享和合作。
织造企业之间可以通过标准化的数据交换和接口对接,共享有关市场需求、原材料供应和技术创新等方面的信息,提高整个行业的竞争力。
此外,标准还可以促进织造行业与其他行业的跨界合作和创新。
通过与IT、材料科学和设计等领域的合作,织造企业可以获得更多的技术支持和市场机会,实现跨越式发展。

Though capable of doubling to 24 GHz with reduced fundamental suppres-sion, the MMIC is designed to take a 4 to 10 GHz input and double it to 8 to 20 GHz. It has integrated output amplifier, matching harmonic suppression, and bias networks. The input/output are matched to 50 Ω and fully DC blocked. The MMIC is fabricated using PHEMT technology. The backside of this die is both RF and DC ground. This helps simplify the assembly process and reduces assembly related performance variations and costs. For improved reliability and moisture protec-tion, the die is passivated at the active areas. This MMIC is a cost effective alternative to bulky hybrid FET and diode doublers that require high input drive power, have high C.L. and poor fundamental suppression.AMMC-6120 Absolute Maximum Ratings [1]Symbol Parameters/Conditions UnitsMin.Max.V d Positive Drain Voltage V 7V g Gate Supply Voltage V -3.0 0.5I d Drain Current mA 120P in CW Input Power dBm 15T ch Operating Channel Temp. °C +150T stg Storage Case Temp. °C -65 +150T max Maximum Assembly Temp. °C +300 (60 sec. max.)Note:1.

The outputs of this balun feed the gates of balanced FETs and the drains are connected to form the single-ended output. This results in the fundamental frequency and odd harmonics canceling and the even harmonic drain currents (in phase) adding in superposition. Node ‘S’ acts as a virtual ground. An input matching network (M/N) is designed to provide good match at fundamental fre-quencies and produces high impedance mismatch at higher harmonics. AMMC-6120 is biased with a single positive drain supply and single negative gate supply using separate bypass capacitors. It is normally biased with the drain supply connected to both the VdAB and the Vdd bond pads and the gate supply connected to the VgD bond pad. It is important to bypass both VdAB and Vdd with 100 pF capacitors placed as close to the die as possible. Typical bias connections are shown in Figure 22. For most of the application it is recommended to use a Vg = –1.2 V and Vd = 4.5 V. The AMMC-6120 performance changes very slightly with Drain (Vd) and Gate bias (Vg) as shown in Figure 8 and 9. Minor improve-ments in performance are possible for output power or fundamental suppression by optimizing the Vg from –1.0 V to –1.4 V and/or Vd from 4.0 to 5.0 V. The RF input and output port are AC coupled thus no DC voltage is present at either ports. However, the RF output port has a internal output-matching circuit that presents a DC short. Proper care should be taken while biasing sequential circuit to AMMC-6120 as it might cause DC short (use a DC block if sub sequential circuit is not AC coupled). No ground wires are needed since ground connections are made with plated through-holes to the backside of the device.Refer the Absolute Maximum Ratings table for allowed DC and thermal conditions.Figure 22.Assembly TechniquesThe backside of the MMIC chip is RF ground. For mi-crostrip applications the chip should be attached directly to the ground plane (e.g. circuit carrier or heatsink) using electrically conductive epoxy [1,2].For best performance, the topside of the MMIC should be brought up to the same height as the circuit surrounding it. This can be accomplished by mounting a gold plate metal shim (same length and width as the MMIC) under the chip which is of correct thickness to make the chip and adjacent circuit the same height. The amount of epoxy used for the chip and/or shim attachment should be just enough to provide a thin fillet around the bottom perimeter of the chip or shim. The ground plan should be free of any residue that may jeopardize electrical or mechanical attachment. The location of the RF bond pads is shown in Figure 24. Note that all the RF input and output ports are in a Ground-Signal-Ground configuration.RF connections should be kept as short as reasonable to minimize performance degradation due to undesirable series inductance. A single bond wire is normally suf-ficient for signal connections, however double bonding with 0.7 mil gold wire or use of gold mesh is recom-mended for best performance, especially near the high end of the frequency band.Thermosonic wedge bonding is the preferred method for wire attachment to the bond pads. Gold mesh can be attached using a 2 mil round tracking tool and a tool force of approximately 22 grams and a ultrasonic power of roughly 55 dB for a duration of 76 ± 8 mS. The guided wedge at an ultrasonic power level of 64 dB can be used for 0.7 mil wire. The recommended wire bond stage tem-perature is 150 ± 2°C.Caution should be taken to not exceed the Absolute Maximum Rating for assembly temperature and time. The chip is 100 µm thick and should be handled with care. This MMIC has exposed air bridges on the top surface and should be handled by the edges or with a custom collet (do not pick up the die with a vacuum on die center). This MMIC is also static sensitive and ESD precautions should be taken.Notes:1. Ablebond 84-1 LM1 silver epoxy is recommended.2. Eutectic attach is not recommended and may jeopardize reliability of the device. Figure 23.

这个月里的时间里,经过我个人的实践和努力学习,在同事们的指导和帮助下,对村的概况和村委会有了一定的了解,对村村委会的日常工作及内部制度有了初步的认识,同时,在与其他工作人员交谈过程中学到了许多难能可贵经验和知识。
通过这次实践,使我对村委会实务有所了解,也为我今后的顺利工作打下了良好的基础。
一、实习工作情况村是一个(此处可添加一些你实习的那个村和村委会的介绍)我到村村委会后,先了解了村的发展史以及村委会各个机构的设置情况,村委会的规模、人员数量等,做一些力所能及的工作,帮忙清理卫生,做一些后勤工作;再了解村的文化历史,认识了一些同事,村委会给我安排了一个特定的指导人;然后在村委会学习了解其他人员工作情况,实习期间我努力将自己在学校所学的理论知识向实践方面转化,尽量做到理论与实践相结合。
在实习期间我遵守了工作纪律,不迟到、不早退,认真完成领导交办的工作。
我在村委会主要是负责管理日常信件的工作,这个工作看似轻松,却是责任重大,来不得办点马虎。
一封信件没有及时收发,很有可能造成工作的失误、严重的甚至会造成巨大的经济损失。
很感谢村委会对我这个实习生的信任,委派了如此重要的工作给我。
在实习过程中,在信件收发管理上,我一直亲力亲为,片刻都不敢马虎。
为了做好信件的管理工作,我请教村委会的老同事、上网查阅相关资料,整理出了一套信函管理的具体方法。
每次邮递员送来的信件,我都要亲自检查有无开封、损坏的函件,如果发现有损坏的函件,我马上联络接收人亲自来查收。
