密封

Spring-loaded safety valve: The compression spring force to the pressure balance valve and to the seal flap.

弹簧式安全阀：利用压缩弹簧的力来针型阀平衡阀瓣的压力并使之密封。

Can be resistant to the replacement of the role of sealing liquid packing, inspection shaft or stem of the concentricity.

可通过更换能抵抗密封液体作用的填料，检查轴或阀杆的同心度。

As a whole, the two cities more than 90 stocks fell, the blue-chip seal Conch Cement limit.

作为一个整体，这两个城市的90多个股票下跌，蓝筹股海螺水泥密封的限制。

BACKGROUND: Glass ionomer cement has been a commonly used filling material in the clinic. However, glass ionomer easily absorbs water and dissolves in early concretionary phase, which can reduce the leak tightness of the edge of obturator, resulting in slightly leakage.

背景：玻璃离子水门汀目前已发展成为临床常用的充填材料，但玻璃离子在凝固的初期易吸水溶解的特性，会使充填体边缘密封性减低，产生微渗漏。

The design mainly works on many factors which effecting the volume efficiency of fracturing pump. These factors are working conditions of the pump,imbibitional valve,expulsive valve,clearance volume,sealing property, condensability of influent, liquid leakage and elastic defletion of pump cylinder. Based on these facors, we should induce the efficiency expression, famulate differential eguation and emulational mathematical model of fracturing pump.

本设计主要针对影响压裂泵容积效率的因素如：泵的工作情况、吸液阀结构参数、余隙容积、密封性能、液体的可压缩性、液体泄漏、泵缸的弹性形变等方面进行分析，在此基础上导出效率的表达式，建立微分方程，并建立压裂泵效率仿真的数学模型。

However, as a result, the meat develops what's known as confinement odour.

但是，这样的结果是，肉会产生一种叫做密封气味的气体。

Secondly, it analyses the line type between stator and rotor of PDM, gets its derivation bone line equation that satisfies the motor conjugate line type of theoretical sealing and the equation of curved surface, and determines its basic processing method and technology according to the line type characteristic of the spiral curve through analyzing some kinds of typical spiral curve processing methods.

其次，对螺杆钻具定子与转子进行线型分析，推导出其满足理论密封性的马达共轭线型的骨线方程和曲面方程，根据螺杆钻具定子内孔螺旋曲线的线型特点，在分析了几种典型的加工螺旋曲线加工方法的基础上，确定了其基本的加工方法和工艺。

The EOS-1V's sealing is the best in Canon's 35mm SLR history; together with "L" telephoto lenses, one can shoot in the worst of conditions. The 100% accurate glass pentaprism viewfinder is as bright and contrasty as any autofocus camera, and custom functions allow personalizaton of autofocus, metering, operating systems, etc. You can also link the EOS-1V to a PC for transfer of data and remote control operation.

是EOS - 1V的的密封是在佳能的35mm单镜头反光历史上最好的，再加上的"L "长焦镜头，可以拍摄条件最差。100％准确的玻璃五棱镜取景器是光明和反差的自动对焦相机，和自定义功能允许自动对焦personalizaton，计量，操作系统等，您也可以链接奥斯- 1V至一个数据和遥控操作电脑的转让。

All parts of this convector, instrumentation of registration of stress and not dependent source for its power supply, hydraulic turbine and electric generator, were built - on in the hermetical pod, eligible to this purpose.

所有这一个对流式暖房器的部份，压迫力的登记使用仪器和不是依赖的来源对于它的力量补给，水力的涡轮和电的产生器，被建造-在密封的荚中之上，这一个目的的有资格者。

This series transformer can meet the modification of oil volume by flexible convexo-concave feature of the corrugate fib so as to make the conservator dispensible.

全密封变压器，通过波纹筋的弹性凹凸变形吸收油体积的变化，无需油枕，使变压器内部与完全隔绝，最有效地保护内绝缘，延长使用寿命。

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！
