High blood pressure, which puts our arteries under greater pressure when the heart beats, affects one in five people and is one of the major risk factors contributing to a cardiac arrest.
高血压是造成心搏停止的主要风险之一。当心脏跳动时，影响1/5人的高血压会令我们的动脉承担更大的压力。
Since cordite burns at a greater rate at a higher pressure a relief valve must be used to allow generated gas to escape to atmosphere at times when the demand is low.
因为柯达火药在较高的压力下以较高的速度燃烧，所以必须使用一个溢流阀，以便当用气少时，能让所产生的部分气体排到大气中去。
At the end of the annular passage, shock wave occurs when the relative lift is less than 6% and the pressure ratio is less than 0.7, which causes a greater total pressure loss.
在相对升程小于6%、压比小于0.7后，环形通道的末端将产生激波，激波带来较大的全压损失。
The relief valve consists of a sealer and an adjusting spring. When the inlet pressure is greater than a set value, the spring pressure is overcome to discharge over-pressure air.
其安全阀是通过密封垫和调节弹簧构成的，当进口压力大于设定值时克服弹簧压力， 把过压气体泄放出去。
Note: When the stroke of slide increased, a balance cylinder should be added to the press to make it smoother. The greater the strokes of slide is, the less the pressure tonnage should be.
提示：滑块行程加大后，请使用带平衡缸机型，使你使用更加平稳，滑块行程越大压力吨位相应减弱。
