失重

When people go out into space, they are away from the earth's gravitational field.

当人们进入太空，他们就离开了地球的引力场，那就没有引力了，他们就处于失重状态。

The motion of the bodies in the direction of weightlessness has been mistakenly defined as gravitational force.

该项议案的机构在失重的方向一直误界定为引力。

The thermal degradation experiments were carried out for some combustibles such as plastic, hardboard, cloth, board, and thipywood which are common in buildings.

对建筑物中常见的几种可燃物：塑料、硬纸板、布料、三合板、木板等，进行了热解实验，给出了其失重曲线，并导出了热解反应动力学参数———活化能E和频率因子A。

In order to reduce the corrosion of acidic paint stripper to aeronautical metals and provide with better anti-corrosion additive for AIL4130, TC4, LY12, and 20(superscript #) steel, a series of inhibitors and their composite were investigated. Weight loss experiment, Tafel curves measurement and SEM observation were carried out for the above metals in the formic acid solution which was normally used in the paint stripper. The experimental results indicate that the optimizing composite inhibitor consists of sodium benzoate, 2-thiourea, hexamethylenetetramine, sodium laurylsulfonate and 1, 2, 3-benzotriazole.

为降低酸性脱漆剂对飞机金属材料的腐蚀，以脱漆剂中经常使用的甲酸水溶液为研究介质，以AIL4130、TC4、LY12、20钢等材料为研究对象，通过腐蚀失重法、塔菲尔曲线测量和SEM观察，筛选出对以上各金属材料缓蚀效果较好的复配缓蚀剂体系，即苯甲酸钠、硫脲、六次甲基四胺、十二烷基磺酸钠、苯并三氮唑等缓蚀剂的优化组合。

Changes in potassium currents of vascular smooth muscle cells isolated from hindquarter arteries of rats after 4 weeks simulated weightlessness.

关于前者，我们已观察到模拟失重大鼠肠系膜小动脉VSMCs的BK Ca及KV电流密度均显著增加，静息电位更负 [10]。

It is speculated that the hyperpolarization of VSMCs and decreased calcium influx through voltage-dependent calcium channels might be one of the electrophysiological mechanisms involved in the depressed vasoreactivity of hindquarter arteries induced by simulated weightlessness.

以上结果提示，VSMCs的超极化及进一步引起的通过电压依赖性钙离子通道的钙内流减少可能是模拟失重引起后身动脉反应性降低的电生理机制之一。

The change of the current density of the L-VDC may also contribute to the depressed responsiveness of hindquarter arteries from simulated weightless rats.

此外，本工作还观察了钙离子通道功能变化，发现模拟失重下肠系膜小动脉VSMCs L-VDC电流密度逐步降低，4 wk时达非常显著程度。

To verify our speculation, we investigated the functions of the voltage-dependent potassium channel and large conductance calcium-dependent potassium channel of VSMCs isolated from hindquarter arteries and cerebral arteries of rats after short- and mid-term simulated weightlessness and compared with that of control rats, using both pharmacological methods and whole cell patch clamp techniques.

为证明我们的推想，我们采用动脉血管环药理学实验方法及全细胞膜片钳技术，来观察模拟失重大鼠脑部及后身动脉VSMCs的两种钾离子通道电压依赖性钾离于通道LK＊与大电导钙激活钾离于通道［BK＊）功能的改变并注意此变化的时程特征。

Previous findings from our laboratory have demonstrated that simulated weightlessness may result in atrophic changes with depressed vasoconstrictor responsiveness in hindquarter vessels, and hypertrophic changes with enhanced vasoconstrictor responsiveness in cerebral arteries of rats.

动物实验结果已证实，模拟失重可使大鼠不同部位动脉血管发生差异性改变：后身动脉血管发生萎缩性改变和收缩反应性降低；而脑部血管则发生肥厚性改变和收缩反应性增强。

An efficient protective material for metal relics was studied in the paper. Volatile rust proofing sieve, vapor inhabitability of mass loss and closed space volatile weight-loss methods were adopted to study many monocomponent volatiles corrosion inhibitors . The best VCI was chosen from them. By mixing, the two composite VCIs were made for iron and copper.

本研究通过采用气相甄别法、失重法和封闭空间挥发减量法实验筛选单组分气相缓蚀剂并进行复配实验，分别制备出铁质文物和铜器文物用的复合气相缓蚀剂，其中铁质文物复合气相缓蚀剂Ⅰ由有机胺A和乌洛脱品以质量比1：1组成，其缓蚀率为96.5％，铜器文物复合气相缓蚀剂Ⅱ由BTA和酚类W以质量比1：1制成，其缓蚀率为94.5％。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
