压力

People are not particularly stressed out right now, and frequently emotional stress changings to physical stress, which changings to worse posture, which changings to pain, which changings to abundance stress,\ says Wendy Young, a certified ergonomist in Houston and author of the e-book, getinsideyourcomfortzone.com.

Wendy Young是一位任务学学者，他说，&目前的大部分人压力太大了，心里压力经常转化为生理上的压力，这会导致大部分人采用更糟糕的任务姿势，进而导火索疼痛，又转化为更大的压力。&

As to multi-layer reservoirs,each layer can be divided into three areas:area of gravel-packing,area of perforation and area of radial flow.Each area has its own governing equaiton and the solution is expressed by Green function.The well bore pressure and layer-rate is given through Green function in Laplace space.The pressure drop and skin factor isobtained also in each area.

根据多层砾石充填完井的渗流特点，将每个产层在径向上分成3个区域，即砾石充填区、射孔区、地层径向流区，每个区域有各自的渗流方程，对n层油藏有3n个渗流方程，将每个区域的方程用Green函数来表示，由各层的Green函数得到井筒混合压力、分层压力及分层产量在Laplace空间上的解，最后得到每层各区域的压力损失、表皮系数以及井底压力和分层产量与时间的变化关系。

The influences of volumetric coefficient, pressure coefficient, temperature coefficient, and leakage coefficient on compressor volumetric efficiency were analyzed.

容积系数主要与压缩机的结构尺寸和吸、排气压力比有关，压力比的变化对容积系数构成以多变膨胀指数为幂的指数影响；转速变化对压力系数构成二次影响；温度系数和泄漏系数同时受到与压力比和转速的影响。

Based on characteristic of silicon microwaves, a new method of pneumatic pressure control is presented.

本文针对硅微控阀门的特性，提出了一种新的气体压力控制方法，设计了基于微机电硅微控阀门的气体压力控制系统，对系统的传感器调理电路、控制电路进行了设计，解决了小压力和低流量时的压力精密控制问题。

Belong to the larger machine, the price from more than 10 million to hundreds of thousands, the difference between the two machines is provided by the pressure of the adequacy of standard nine millibars of pressure is atmospheric pressure, although small home appliances machine is constantly The improvement, however, constrained by the cost, so the pressure it is still to be questioned.

属於较大型的机台，价格从十几万到几十万，这两种的差别就在於机器所提供的压力是否足够，标准的压力是九毫巴的大气压力，小型的家电机器虽然也是不断的改进中，但受制於成本，因此它所产生的压力仍是有待质疑的。

Methods The investigation object were staff nurses (n=915). By using a questionnaire method, the demographic information, job stress, and the relationship between stress and stress resource, stress coping, social support was analyzed.

方法采用问卷调查法，对915名临床护士的人口学特征、工作压力程度以及压力与压力源、压力应对、社会支持状况之间的关系进行分析。

While there are different types of relief valve designs, the basic principle is that when the pressure in the equipment exceeds the relief valve's set pressure, the relief valve will open and remain open until the pressure is reduced below the set pressure, after which the relief valve recloses to seal the system.

安全阀虽然有不同种类的设计，但他们的基本原理是一样的，当设备里的压力超过安全阀的设置压力时，安全阀就会打开卸压，直到设备里的压力降低到低于设置压力后安全阀会重新合上，并保持系统封闭。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.
