然后从该式出发，不仅可以得到有孔隙的耦合热弹性体动力学的虚功原理和互等定理，而且能系统地导出成互补关系的11类变量、9类交量、6类变量及3类变量简化Gurtin型变分原理。

The interoperability of digital libraries is becoming more and more important with the development of digital resources.

随着数字图书馆的发展，各种资源间的互操作性也变得越来越重要，人们也一直致力于对分布式资源进行统一检索的开发。

SEM result showed that the sample had uniform phase distribution and smooth surface at dried state as well as interpenetrate network structure at hydrogel state. It was seen from the swell ing behavior curves that groups T1, T2 and T3 swelled rapidly within 10-30 minutes, and formed elastic composite hydrogel pipes. In addition, the expanding ratio of inner and outer diameter of the tube was 20%-30% and 100%-120% with swell ing, respectively. The equil ibrium water content of the hydrogel pipes increased with increase of collagen composition. Three groups of samples were immerged in PBS solution contained 2 mg/mL lysozyme at 37 for 1 month, their nozzle cracked, their wall became thin and more transparent. And also, there was small floc deposited on the tube surface.

扫描电镜观察到液氮脆断的人工泪小管内部成分分布均匀，内外壁表面平整，冷冻干燥的人工泪小管断口呈凝胶态的互穿网络结构。3 组不同成分的人工泪小管在PBS 溶液中浸泡30 min 后均快速吸水溶胀，外径扩大100%～ 120%，内径扩大20%～ 30%，并且随胶原含量增高，溶胀速度增快，平衡溶胀率增大。3 组人工泪小管在37℃含2 mg/mL 溶菌酶的PBS 液中浸泡1 个月后，表面有部分细小絮状物，管口开裂，管壁变薄，透明度增加。

虚功原理和结构位移计算：理解变形体虚功原理的内容及其应用，熟练掌握在荷载作用下静定结构位移的计算方法，掌握静定结构在温度变化，支座移动影响下位移的计算方法，了解互等定理。

Based on the reciprocity theorem, the analytic solutions of electric field induced by time-varying magnetic field were obtained when the boundary of volume conductor is infinity, semi-infinity and prolate spheroid respectively.

根据互易定律，给出了容积导体为无限大、半无限大及边界为长球面三种情况下，时变磁场产生的感应电场空间分布的解析表达式，它是进行磁刺激理论及试验研究的基础。

Lateral branches penetrating leaf sheaths. Leaves alternate. Inflorescences borne at each node, opposite leaves, emerging from mouth of leaf sheath, each a large panicle of numerous cincinni; cincinni each subtended by an involucral bract; bracts similar to leaves, becoming smaller toward apex of cincinnus.

叶互生 花序着生在每节，与叶对生，从叶鞘口那里出现，每一个为一大的多数蝎尾状聚伞花序的圆锥花序；蝎尾状聚伞花序各自以一总苞片被包着；类似于叶的苞片，向蝎尾状聚伞花序先端变小。

This is because natural selection emblematizes the ecological interaction of a population, whereas drift is regarded as a sampling procedure across successive generations without regard to fitness pressures imposed by the environment.

这是因为自然选择象征着一个群体的生态互作，而漂变被视为不考虑环境对适合度所施压力的、在连续世代里的抽样过程。

The writer simplifies and induces thin-bedding medium in the East of China to several seismogeologic models: wedge model; thin-bedding group in which two mediums have equal thickness, thin-bedding group in which two mediums have not equal thickness and formations whose thickness orderly gradates from top to bottom.

本文通过对某油田的若干口钻井的测井曲线和岩性资料进行分析研究，认为我国东部油区的薄互层地层的地质特征为：①大多数地层为低于目前地震勘探分辨率的薄层或超薄层；②地层在横向上相变剧烈；③地层结构具有多种类型。

At here, based upon designing idea of the shearing planes of left and right two shears are at ±45° with respect to main transmission plane and the combination with changeable structure, the shearing mechanism of two mutually twisted flat screw wires was designed.

在此，基于左右两把剪刀的剪切平面相对于主传动平面成±45°，以及与变结构相结合的设计理念，设计出了两根互绕扁螺旋钢丝的剪切机构。

As for any potential awkwardness after the fuct, UNCUT, if the hottest guy you've ever swapped blowjobs with in your life—presuming the exchange of blowjobs goes down—is cold and distant, or even hostile, it might be because he doesn't want to get with you again.

至于事后有可能的尴尬情况，没割，如果这个最辣的同志是你唯一互相口交过的人—假如后来的互交减少—甚至变得冷漠、疏远甚至有敌意，可能是他不想和你继续了。

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.

要是在劳改农场，你等着挨绳子吧！
