收缩

The first batch cracks of concrete bodies in South China had been caused by temperature stresses of cement hydration heat.While the double-action of (1) expansion stress of concrete and (2) temperature stress of day and night's difference of temeperature had been mainly the cause of cracks.

在南方地区，混凝土墙体拆模后的第一批裂缝是由于水泥水化热引起的温度应力造成的，而混凝土收缩引起的收缩应力与昼夜温差引起的温度应力的双重作用，则是导致后续裂缝的主要原因。

METHODS:In rivo observing the inhibitive effects of POT on the cough caused by ammoniacal smoke in mice and the bronchospasm caused by the mixture of histamine and acetylcholine or egg albumin in normal gainea pigs and the passive cutaneous anaphylaxis reaction in mice,respectively.

通过整体实验，观察麦冬多糖对氨雾引起小鼠咳嗽和对以组胺和乙酰胆碱混合液引起豚鼠支气管收缩及对小鼠耳异种被动皮肤过敏和以卵白蛋白诱发的致敏豚鼠支气管收缩的影响。

Its framework contracted but not expanded as expected when it was electrolytically colored. This probably resulted from the attraction of O atom and Li〓 that was injected the interstice of WO〓 framework.

WO〓薄膜在电致变色过程中，其"骨架"没有发生扩张，反而收缩，这可能是注入的Li〓占据了WO〓的骨架空隙，与O相互作用产生向内的收缩力所致。

Methods The electromyogram of a dog's orbicularis oculi muscle was extracted with implanted micro-electrodes, The difference of electromyographic activities during different functional states was investigated to establish a way for real-time identification of functional states.

结果 眼轮匝肌在收缩时的肌电信号相对于舒张状态有幅值显著增加的特点，基于这种特征，我们采用了一种带延迟判断的幅度阈值方法，对信号进行实时分析，以接近于同步的方式识别出了眼轮匝肌收缩动作的发生。

The appearance of firefighter's clothing after flame engulfment was also analyzed. The analysis indicated that the more integrity the inner layer of clothing had after exposure, without brittleness and shrinkage, the more protection the clothing was. At the same time, the accessories on the firefighter's clothing were also crucial, especially for membrane and retro-reflective stripes. If they shrink in the exposure of flame, the protection of the clothing would reduce.

由检验各消防衣的外观来分析，则可知如果使用的材料在进行火焰冲击时，能够使防护衣仍具有完整的结构，且不产生脆化与收缩，则愈具有防护能力；同时对於消防衣上的零配件也要格外注意，尤其是薄膜与反光条，若此处产生热收缩，就会减低消防衣的防护能力。

The present study was performed to observe the time course and features of intermittent tetanic contractile function changes in soleus and extensor digitorum longus muscles of tail-suspended rats. The optimal stimulating frequency, fatigability and time-dependent recovery after fatigue were measured in isolated muscle strips.

为观察模拟失重对大鼠比目鱼肌(soleus， SOL)与趾长伸肌(extensor digitorum longus， EDL)间断强直收缩功能的影响，以及对刺激频率的调节作用，采用离体骨骼肌条灌流技术，观测其产生强直收缩最大张力的最适刺激频率、疲劳性与疲劳后恢复过程。

Fruit a berrylike indehiscent drupe with pyrenes 2 × as many as styles, globose, in dried material characteristically longitudinally angled, squarish or rectangular in longitudinal cross-section, with flattish apex and base, contracted or not at equator, disk persistent at base, style or stigma remnants persistent at apex.

果浆果状的不裂的核果的，具果核数为花柱的2倍，球状，在干标本上明显具纵向的角，纵向截面近似方形的或长方形的，具平的先端和基部，收缩或在赤道轴上不收缩，花盘宿存在基部，花柱或柱头残余在先端宿存。

Masseter "strongest;" 975 pounds for 2 seconds; gluteus maximus and quadriceps strongest if leverage not included

心肌和平滑肌的收缩不由意识控制且为生存所必需，例如心脏的收缩或是肠胃道的蠕动等。

Goode, MD, from the Department of Veterans Affairs Medical Center in Birmingham, Alabama, and colleagues."This provides a form of passive exercise with the goal of improving the urethral closure mechanism."

Goode博士表示，PFES 对於无法辨别或收缩骨盆底部的肌肉收缩，是具有教导效果的，这可以提供一种被动的训练，以达到改善尿道关闭机制的目标。

After undertaking to the interact of dwell pressure, dwell time and mould temperature orthogonal experiment makes an on-the-spot investigation, reach: Material of miscellaneous 赑 OM(N2720 M63) and material of UHM WPE(GUR EP4221), the interact that basically is dwell time and mould temperature affects the systole of gear to be out of shape, to PA66(RTP 0205) material the systole that basically is gear of dwell pressure and influence of dwell time interact is out of shape.

对保压压力、保压时间和模具温度的交互功能进行正交实验考察后得出：对于POM(N2720 M63)材料和UHM WPE(GUR EP4221)材料，主要是保压时间和模具温度的交互功能影响齿轮的收缩变形，对于PA66(RTP 0205)材料主要是保压压力和保压时间交互功能影响齿轮的收缩变形。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.

万寿菊对土壤要求不严，以肥沃。排水良好的砂质壤土为好。

He unstepped the mast and furled the sail and tied it.

他拔下桅杆，把帆卷起，系住。
