Pascal's law is illustrated by the operation of a hydraulic press, shown in fig 12-3 . 如图12-3帕斯卡定律可用液压机的作用来说明。
The maximum density is governed by the allowable limit of fluidity for hydraulic transport . 最大密度是由水力输送所容许的流态极限控制的。
Loading was achieved through a battery of hydraulic jacks acting on a rigid metallic distribution plate . 通过作用于刚性金属垫板上的一组液压千斤顶加载。
These loads are normally applied by hydraulic jacks acting directly at the point of application of the force . 通常这些荷载是用液压千斤顶直接施加于力的作用。
Less frequently we apply the load directly to the surface by means of hydraulic jacks and distribution plates . 用液压千斤顶与分布板直接施加荷载于表面的方法较不常用。
In front brakes it is usual to hydraulic cylinders in order to equalize the pressures exerted by the shoes . 在前制动器中，通常使用两个液压缸，用以平衡制动蹄所产生的压力。
Hydraulic fill dams are built of sand and silt brought into the dam in a stream of water, usually through a pipe . 水力冲填坝通常是用一根管子利用水流把砂和粉沙运到坝体处筑坝。
Loads are commonly applied with universal testing machines, hydraulic cylinders dead weights, or some form of pressure . 通常是用万能试验机、液压缸重物或某种形式的压力施加载荷。
According to their building material, dams are described as concrete, earth fill, rock fill, hydraulic fill and so on . 按照筑坝所用材料，可以把坝称为混凝土坝、填土坝、堆石坝，水力冲填坝等等。
A small leakage through an earth fill or hydraulic fill dam or its foundation removes some fine material in suspension . 贯穿填土坝、水力冲填坝或坝基的一个细小的漏水孔隙以悬浮的方式带走一些细小的土粒。
