YXK-160 bit type control pressure gauge use the bourdon tube as the snsitive element, while controllingthe liquid medium pressure, itcan indicate the pressure value.

YXK-160 位式控制压力表采用弹簧管作为测压敏感元件，在对被测流体介质压力进行控制的同时，可同步指示出被测压力值。

Pressure and temperature properties of fiber grating bourdon tube pressure sensor［J］.

Boyle's law is a law about gases. It states that if you increase the pressure on a gas, its volume decreases. This is like if you were to squeeze a balloon, the pressure of the air inside the balloon increases while the volume of the air decreases.

波以耳定律是关於气体的定律，该定律说明若增加气体的压力，气体的体积就会变小，这就像你若挤压一个气球，气球内空气的压力增加，体积却变小。

Along with the aggravation of market competition, China Unicom Anhui Brach is facing with more and more pressures.

随着市场竞争格局的进一步形成，电信企业间的竞争不断加剧，安徽联通面临着更多的内外部压力：对内，成本压力越来越大，塞班斯法案的颁布对内控提出严格要求；对外，3G的商用日益临近，业务的多样性带来运营模式的多样性，这些都对支撑系统提出了更高的要求。

Along with the aggravation of market competition, China Unicom Anhui Brach is facing with more and more pressures. On the one hand, the internal pressure of cost pressure is greater and the promulgation of Saipan Si bill also makes stricter request for internal cost control. On the other hand, with commercial service of 3G approach gradually, the variety of the service brings the variety of the business pattern, which request support system to be more suitable and facil.

Pressure ulcer prevention relies on managing or eliminating risk factors, including diminished patient mobility, pressure to bony areas that compromises blood flow to areas of potential breakdown, shearing and friction that occur secondary to prolonged immobility, suboptimal nutritional status, and prolonged skin contact with moisture.

压力溃疡预防依靠处理或消灭风险因素，包括被减少的耐心减弱对潜在的故障区域的血流，剪的流动性、发生次要对长时期的固定性、最适度一下的营养状态和与湿气的长时期的皮肤接触的压力对骨多的区域和摩擦。

The ratio of the breaking stress of a structure to the estimated maximum stress in ordinary use.

间断压力同最大压力的比率。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
