结构破坏

Geometrical models and finite element models are set-up and calculations on the model are made both by using the software MSC/ PATRAN, which is convenient for applications.

如果能够找到应力集中或者结构变形最大的地方，就可预知结构可能在哪里发生破坏，继而采取相应措施。此外，省材和节能都有非常重要的意义。

After Cunninghamia lanceolata cones were infected by Pestalotiopsis apiculatus ,the ultrastructure of diseased cone scale cells showed a series of pathological changes according to the different infected degrees and it mainly showed that the granum lamella structure and membrane structure of the chloroplast were destroyed

侵染后，罹病果鳞细胞的超显微结构依侵染程度不同表现一系列病理变化，主要表现在：叶绿体的基粒片层和膜结构遭到破坏

When the mesostructure is basically formed, the pH value of the reaction system is adjusted to 7-8 and then the hydrothermal crystallization is prolonged for some time to obtain heteroatom-incorporated mesoporous silica. The aim of adjusting pH value to near neutral is to change heteroatom species from the cationic to oxo form and therefore can enter the mesoframework through condensation with silanol groups in the wall.

该方法主要的特点是：操作简单（以调节体系pH值代替繁琐的后处理过程），效率高（可以得到Si/Al=5且铝物种全部处于四配位的骨架位置的Al-SBA-15），不破坏产物有序结构（产品具有高度有序的介孔结构），具有普遍性（适用于多种杂原子的掺杂如铝、钛、钒）。

The problem of fatigue damage of metal structures has been found in engineering field for a long time. As a whole of metal structure, about 80%~ 90% fatigue accidents are related with fatigue and rapture.

金属结构的疲劳破损是工程界早已发现的问题，就金属结构的总体来看，大约80%～90%的破坏事故和疲劳与断裂有关。

The monotone industrial structure, economic decreasing, lots of lay off ,destroying of environment, and so on.

其中许多城市随着资源开采进入衰退期或枯竭期而成为资源枯竭型城市，面临着产业结构和所有制结构单一、经济增长缓慢、失业率增加、生态环境破坏严重等问题，城市产业转型势在必行，转型中困难较多，充足的资金是一个必要的前提条件，而大力吸引并有效合理利用外资无疑是一种必然选择。

The authors studied the reliability of earthquake-resistance and shear-resistance of multistoried stone structure,by taking account of the randomness and fuzziness of earthquake intensity and the fuzzy boundaries of intensity damage scales of stone structure.

通过考虑地震烈度的随机性和模糊性，以及石结构强度破坏等级界限的模糊性来研究多层石结构抗震抗剪能力的可靠性问题。

The influences of INA on ovule ultrastructure were also researched. The plasmolysis phenomenon occurred in the nucellar cells, a great deal of bubble structures existed in the cytoplasm, the sterility of plastosome was disarranged or the structure was entirely damaged and turned transparent.

INA细菌对胚珠的超微结构的影响表现为：使珠心细胞发生质壁分离现象，细胞质中存在大量泡状结构，线粒体的嵴紊乱或结构完全被破坏，呈透明状。

Numerical example showed that the random manufacturing deviation produced large initial stress, which induced buckling failure of some spatial grid members, and had a large effect on the safety of the grids structures and could not be ignored.

正交正放四角锥网架的算例结果表明，随机制作偏差可以引起的较大的初始应力，使得网架结构局部杆件发生失稳破坏，从而对结构的承载力有较大影响，不容忽视。

Through dynamic analysis, the structure can not be shaken, fatigued and broken under environment of sin scan and random vibration.

通过进一步对整个组件结构进行动力学分析可知，结构在正弦扫描和随机振动工况下不会发生颤振、疲劳和破坏。

The chloroplast ultrastructure of the sepal in the fresh-cut broccoli florets was investigated with a transmission electron microscope.

对鲜切西兰花叶绿体超微结构的研究表明，乙醇对叶绿体外膜及内部基粒片层结构均起到保护作用，减小了贮藏期间叶绿体的破坏程度，显著延缓了叶绿体结构的解体。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.
