这个定律表明在一个密封的容器里，如缸体或管子，受压液体向容器表面所有方向施加相等的力。
This law states that pressurized fluid within a closed container-such as cylinder or pipe-exerts equal force on all of the surfaces of the container.
我们知道，力可以叠加，这样产生的总的力是大于单个个体的，力也可以抵消，这样总的合力是小于单个力的，力也可以叠加产生的合力是于单个个体相等的。
As we know, the force can be put together, the total force is greater than the single one. They can conteract each other, so the combined force can be less than a single force.
巨无霸指数基于购买力平价理论，该理论认为汇率应该使不同国家的一揽子商品的价格相等。
THE Big Mac index is based on the theory of purchasing-power parity (PPP)—exchange rates should equalise the price of a basket of goods in different countries.
地球也会坠向苹果-，因此地球上的力与地球的质量相等，再乘以地球的加速度。
Well, the earth is going to fall towards the apple — So the force on the earth is the mass of the earth times the acceleration of the earth.
向上的力与向下的力相等，所以气球就维持正在这一高度。
The force upward equals the force downward so that the balloon stays at the level.
向上的力与向下的力相等，所以气球就保持在这一高度。
The force upward equals the force downward so that the balloon stays at the level.
经过一些时间的自由降落后，落体运动得很快，以至空气拽力(阻力)与落体的重量相等，于是就没有加速度了。
After some time of uninterrupted fall, the body is moving so rapidly that the drag of the air is as great as the weight of the body, so that there is no acceleration.
如果你下降3米，就是说地球把你向下拉3米，但你也对地球施加了一个大小相等，方向相反的力。
If you fall 3 meters, the earth is pulled you down 3 meters, but you have also exerted an equal and opposite force on the earth.
理论上，一个无摩擦力的，或者说是理想的机器，输入和输出的功相等，因此效率是1，或者说是100%。
In a theoretically frictionless, or ideal, machine, the work input and work output are equal, and the efficiency would be 1, or 100%.
当浮子上升的力与浮子所受的重力、浮力及粘性力三者的合力相等时，浮子处于平衡状态。
When the float upward force and float suffered gravity, buoyancy and viscous forces of the force equal to three when the float is in equilibrium.
在流化床中，流体通过固体颗粒床层，其流速足够产生一个与颗粒重量相等的向上的力。因此而使颗粒悬浮。
In a fluidised bed a fluid is passed through a bed of particulate solids at a velocity sufficient to provide an upward force equal to the weight of the particles, therefore buoying the particles.
欧盟国家可以自此获得和美元相等的货币，还享有对国际货币制度更大的影响力。
The European Union can obtain the currency which equals to American dollar, and it has a great influence on international currency system.
假使两方面保持平衡，那么所有这些小的不规则的力对活塞的有效作用必须与重力相等。
The net effect on the piston of all these small irregular forces must be equal to that of the force of gravity if there is to be equilibrium.
另一种定义货币的公平价格方式是购买力平价，其理念是：从长久来看，国家之间的汇率应该使价格相趋于相等化。
An alternative way of defining the "fair" value of a currency is purchasing-power parity (PPP) : the idea that, in the long run, exchange rates should equalise prices across countries.
若实验过程中假设钢管的弹性模量和钢材的弹性模量相等且为常数，则保温层摩擦力和无保温管与有保温管伸长量之差成正比；
The experiment is assumed that the elastic modulus of the steel pipe equal and constant, the insulation layer friction proportional to the difference of elongation.
