真空的

In the state of vacuum,the boilling point of raw material will be dr-opped.therefore it is suitable for drying raw materials that are unstable or thermalsensitive.the vacuum drier also has good airtighenss.so it is also for drying raw materials that contain strong irriative and toxic gases and toxicgases and the solvent needs to recover.

真空状态下物料溶剂的沸点降低，所以适用于干燥不稳定或热敏性物料；真空干燥机有良好的密封性，所以又适用干干燥需回收溶剂和含强烈刺激，有毒气体的物料。

Fourth, to avoid breaking material: Screw must not be allowed in the case of blanking operation, upon occurrence of the stator as dry friction of rubber, produces instant heat and burn, so good grinder, screw grille flow is a necessary condition for normal operation To this end, some screw pump body is also expected to stop off device installed, when there Fracture, because he has a self-priming screw pump function of the characteristics Chemical pumps of the body will produce a vacuum chamber, vacuum screw pump will stop operation.

四、避免断料：螺杆泵决不允许在断料的情形下运转，一经消防泵发生，橡胶定子由于干摩擦，瞬间产生高温而烧坏，所以，粉碎机完好，格栅畅通是螺杆泵正常运转的必要条件之一，为此，有些螺杆泵还在泵身上安装了断料停机装置，当发生断料时，由于螺杆泵其有自吸功能的特性，腔体内会产生真空，真空装置会使螺杆泵停止运转。

Screw must not be allowed to break at the expected operating circumstances, once happened, rubber stator do because of friction heat generated instantly burned, so, good grinder, screw grille flow are a necessary condition for the normal operation of one of For this reason, some screw pump was also installed devices break down material, when the expected happened when broken, because of the screw pump has self-priming function of its characteristics, the body will produce a vacuum chamber, vacuum devices will stop screw operation.

Screw does not allow for the case of run-off materials, once occurred, rubber stator due to dry friction, the heat generated instantly burned, so grinder intact, grille flow is a necessary condition for the normal operation of pumps, one of To this end, some screw pump is also installed in the body break down plant material, as occurs when the material off, because he has a self-priming pumps feature the characteristics of the body will produce a vacuum chamber, vacuum devices will screw pump to stop operation.

Vacuum Pump is a two stage pump capable of .1 micron can be used for applications such as freeze-drying, vacuum deposition, centrifuging, mass spectroscopy, electron microscopes and evacuation of cathode ray and other gas tubes.

L 真空泵是一种二级泵，它能处理1微米的压强，它能用于冷冻干燥、真空淀积、离心过滤、质谱分析、电子显微镜、抽真空阴极射线和其它的离子管的应用中。

The results show that a diffusional transformation takes place when the alloy is heated over 850 ℃ for a long time, and a new precipitation3 Ti with an hcp structure can he found.

结果表明，非真空热处理、真空热处理这两种热处理方式的最大回复应力σr^m变化不大，而冷拔态下合金的最大回复应力值σr^m远远高于其他两种状态的回复应力。

Results of experimental research on diamond surface metallization with electrolyse plating and vacuum plating show that strength, thermal stability and penetration rate of metallized diamond are much better than that of nonmetallilized diamond, and performances of diamond plated with Ti are the best among all plated diamonds.

利用化学镀和真空镀 2种方法对金刚石表面进行金属化处理的试验研究结果表明，镀膜金刚石较未镀膜金刚石的抗压强度、热稳定性等性能和碎岩效果均有很大提高，其中真空镀Ti的效果最好。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.
