跪式可以在你用力推时，转移一部分对脊椎的压力，甚至能比坐式更有效的减轻分娩的痛苦。
Because kneeling allows you to shift and transfer some of the pressure toward the lower spine while you push your baby out, it seems to reduce childbirth pain even more than sitting does.
被称为多尔·切斯特2 (DorchesterLevel 2)的陶瓷装甲，在英国挑战者2型(British Challenger 2)坦克使用，据报道说至少可承受比相同重量钢铁能承受压力的三倍。
A ceramic armour called Dorchester Level 2, used on British Challenger 2 tanks, is reportedly at least three times as resistant to some strikes as the same weight of steel.
该方法可适于任意形状的燃烧室，能反映出喷油压力、喷油嘴结构及安装位置、进气涡流比等参数与燃烧室形状的匹配关系。
The method can be used for combustion Chambers with any shape to match the fuel injection pressure, nozzle construction, injector position and intake swirl ratio with chamber shape.
因此，该装置有二个优点：(1)工作压力比一般冲击气缸高，所以能增加输出功。
Therefore, this device has two advantages: (1) the pressure of impact cylinder may be higher than usual, so that the output can be increased.
双射流是由中心直射流和同轴的环形旋转射流形成的一种新型高效射流，用双射流能够克服门限压力与高破岩比能的制约而高效破岩。
Dual-jet is a new kind of high efficient jet, which is formed by combining round straight jet with circular conical swirling jet.
此模型能根据实测的燃烧压力曲线计算出层流燃烧速度、已燃气火焰温度及火焰传播速度等参数随压力、当量比、发动机转速、点火提前角的变化规律。
The variation of combustion velocity, fired gas temperature and flame propagation speed, when the press, excess air ratio and ignition timing changed, was calculated by this quasi-dimensional model.
通过对数据分析，发现泡沫铝壳不仅可以消减爆炸冲击波峰值压力，而且可以有效地吸收冲击波比冲量和冲击波比能。
The experimental data analysis show that aluminum foams shell not only can weaken the peak pressure, but also effectively absorbs the specific impulse and the specific energy of shock wave.
对于我们其他人而言，运动非常重要，有什么比学习拳击然后在休息时邀请你讨厌的同事或领导来一场友谊赛更加能缓解压力的方法呢？
For the rest of us though, exercise is vital, so what better way to bring down your stress levels than by taking up boxing and inviting hated colleagues and superiors to join you for a lunchtime bout?
