使变形

Working Principle Transmitter is composed of sensor and electronic element circuit, pressure of measured medium directly applies on sensor s ceramic diaphragm, force diaphragm to displace tinily in proportion to pressure of medium, under normal working condition, diaphragm displace no more than 0.025mm, electronic circuit detects this displacement, and convert it into standard industrial measuring signal i.e.

工作原理变送器由传感器与电子元件线路组成，被测介质的压力直接作用于传感器的陶瓷膜片上，使膜片产生与介质压力成正比的微小位移，正常工作状态下，膜片最大位移不大于0.025mm，电子线路检测这一位移量后，即把这一位移量转换成对应于这一压力的标准工业测量信号（4~20）mA。超压时膜片直接贴到坚固的陶瓷基体上，由于膜片与基体的间隙只有0.1mm，过载时膜片的最大位移只能是0.1mm，所以从结构上保证了膜片不会产生过大变形。

This paper, which focused on the structure optimization theory and method, has finished such studies as follows: The three dimension model has been built, which provide the necessary conditions for the building of the dynamics equivalent model. By the launch dynamics simulation, the loads of the key joints when the rocket is launched has been got, which provide the necessary data for the finite element analysis and the structure optimization. The finite element model of the excess weight parts of the rocket has been built, buy the finite element intension analysis of the model in two conditions, the displacement and the stress of the key points have been got, which make us know the distributing of the stress and the transmogrification of the part. To satisfy the intension and the precision design request and to decrease the weight of the part as many as possible, the part has been topology optimized by the structure optimization theory and method. After that, the new model has been analysis in structure and launch dynamics. The contrast of the character change of the old part and the new part and the influence on the rocket system have been studied.

本文以结构优化理论和方法为核心，主要做了以下工作：建立了某自行火箭炮全炮三维实体模型，为建立该火箭炮系统的动力学等效模型提供了必要条件，进行了发射动力学仿真，得到该火箭炮发射装置各关键连接部位在发射状态下的载荷，为有限元分析和结构优化提供了必需的数据；建立了该火箭炮发射装置超重部分的有限元模型，分两种工况，对模型进行了有限元强度分析，得出了关键部位的位移和应力值，对其的应力和变形分布有了具体的了解；运用结构优化的理论和方法，对该火箭炮发射装置超重部分进行了拓扑优化，使其在满足强度和精度的要求下尽可能多地减轻重量，对优化后得到的模型进行了结构分析和发射动力学分析，对比了该部件优化前后的特性变化以及对火箭炮系统的影响。

The main components of the lathe are the headstock and tailstock at the oppoaite ends of a bed,and a tool-post between them which holds the cutting tool.the tool-post stands on a cross-side which enblesit to move sidewards across the saddle or carriage as well as along it,depending on the kind of job it is doing.the ordinary centre lathe can accommodat only one tool at at time on tool-post,but a turret lathe is capable of holding five or more tools on the revolving tueeet.

刀架位于一个纵面板上，小拖板使刀架能够根据加工操作的不同作纵向移动；同时又随大拖板作横向移动。普通顶尖车床只能在刀架上夹持一件刃具，但六角车床可以在其旋转的六角刀架上夹持五件或更多的刃具。车床的床身必须很牢固结实以避免在受力的时候弯曲和变形。请提问的同学最好参观一下工厂的金属切削/机加工车间。那里有车床，还有其他种类的金属切削机床。

The lumped quality matrix and lumped dumping matrix are used to uncouple the group of simultaneous equations.

钣料成形是利用模具使钣料发生塑性变形成壳体零件的生产技术。

In addition, the cover layer too thick, provincial and municipal governments may also make the rubberand layout Department drastically plastic deformation to the detriment of the thickness of the rubber blanket unitormity, when the change has been printed on other products may occur when the local pressure underrun.

此外，覆盖层功薄功硬，还会使橡皮结构部爆发较不小的不弹性变形，爱护橡皮布薄量的平均性，当换印其他产物时会呈现部不合不张力不敷本体。

Thirdly, they migrate to a certain direction. Asthenosphere movement leads to the movement of depression-uplift structure. Crustal surface shows undulatory movement due to the asthenosphere. Deformation and movement law of depression-uplift structure accordingly develops.

坳陷构造运动的动力是软流圈运动的结果，软流圈作波动运动使地壳表层也作波动运动，并形成相应的坳隆构造变形和运动规律。

Uniform scale is supported, but non-uniform scale cannot work with instances in Gamebryo because non-uniform scale is baked into the geometry.

均匀缩放是被支持的，然而，不能对Gamebryo中实例进行不均匀缩放，因为不均匀缩放会烘培几何体（使几何体发生不规则变形，max有烘培一个操作）。

The conidia formation was inhibited on the PDA agar plate with the culture filtrates though the spores germinated and formed their hypha in certain degree. Growth suppression, increasing branches of their offset and swelling in the middle and/or the top of the hyphae were observed with microscope and scanning election microscope. The longer time the treatment, the more severe the hyphae aberration was, some of them were altered as beadlike, some offsets formed cluster-like structure.

在普通光学显微镜和扫描电子显微镜观察显示，两菌株均可抑制香蕉炭疽病菌菌丝生长，造成菌丝分支增多，顶端和中央膨大，随着时间的延长畸变结构增加，菌丝呈念珠状或菌丝分支显著增多，且顶端细胞变形膨大聚集成簇，菌丝壁穿洞，内含物质泄漏，终使细胞崩解和消融，变成球状的空泡。

12Rowling has refused to tell curious fans what the forms of Snape's boggart and Patronus are, as such an in-depth look at Snape's greatest fears and most cherished memories would give too much away.

Rowling 拒绝了告诉好奇的书友们斯内普的 boggart （变成看见者最害怕物体的变形鬼）和 Patronus的形状，因为那将使我们看到斯内普最大的恐惧以及最珍贵的记忆，这样一来就会透露太多秘密。

A study of phase morphology of PBT/POE-g-MAH/nano-CaCO3 composite by means of scanning electron microscopy showed that the domains size of nano-CaCO3 capsulated by POE-g-MAH elastomer in composite when PBT was mixed directly with POE-g-MAH and nano-CaCO3 together or with nano-CaCO3 capsulated by POE-g-MAH elastomer is large.

采用熔体流动速率较低的EPS30R与纯POE-g-MAH共混制备的增韧改性剂，在PBT基体中的分散相变得粗大且不均匀，共混物的脆韧转变推迟。SEM显示，纯POE-g-MAH增韧剂使PBT共混物发生脆韧转变时，弹性体分散相颗粒产生塑性变形，诱发基体屈服而吸收能量。
