流体静力学

The unit of hydrostatics takes the concept of buoyant force as its base, the Archimedes theory as its kernel, and the condition of sink or emerge as its representation.

"浮力"是流体静力学中应用性较强的基础知识之一，也是初中物理教学的重要内容。

Basee on the mixing-length theory of convection, macroscopical stress of the turbulence is used in hydrostatics equation of the stellar structural and evolutionary model.

以恒星结构与演化理论中常用的混合程理论为基础，将湍流作用表现出来的宏观应力引入恒星结构与演化模型中的流体静力学平衡方程。

The stability criteria on the hydrostatics theories are used to estimate whether aship in the heavy seas capsize or not,this method ignores the time domaincharacteristics, frequency characteristics and the randomicity of ship motions. Thecapsizing accidents occur now and then although ships are designed according tostability criterion. So, it is also the important problem for human beings to investigatethe nonlinear characteristics of ship motions and evaluate the survival ability of ships.

目前的稳性标准是根据流体静力学理论来评判船舶在风浪中的安全行为，这种方法忽略了船舶运动的时域特性、频域特性及随机性，按照目前稳性规范设计的船舶仍然时有倾覆发生，因此研究船舶的非线性运动特性和评估船舶航行的生存能力，仍然是人类面临的重大课题。

It's form is the contribution of the Reynolds stress tensor and magnetic fluctuating tensor.

主要的表现是：第一，Reynolds stress 张量和磁扰动张量的径向分量贡献给压强，引起太阳内部流体静力学平衡方程和太阳内部热力学变量的改变，从而导致温度、密度、内能、绝热指数以及绝热温度梯度等的变化。

The forms in Figure 1 must be capable of resisting both hydrostatic and gravity loads.

在图 1 的表格一定能够抵抗流体静力学和地心引力负荷。

The cylinders are initially hydrostatically testedto pressures two to three times the service pressure.

最初，在压力为工作压力的两到三倍的情况下对钢瓶进行流体静力学测试。

Cylinders in carbon dioxide service are hydrostatically tested upon manufacture, and every five years thereafter at 5/3 times the service pressure.

用于二氧化碳的钢瓶在制造时经过了流体静力学测试，之后每五年进行一次在5/3倍工作压力下的测试。

In addition, gas producers must make certain the cylinder closure is completely leak-tight, and that cylinders are internally inspected and hydrostatically tested at the prescribed time intervals.

另外，气体生产商必须确定钢瓶的密封是彻底防漏的，在指定时间间隔内要进行钢瓶内部检查和流体静力学测试。

In addition, gas producers must make certain the cylinder closure is completely leak-tight, and that cylinders are internally inspect ed and hydrostatically tested at the prescribed time intervals.

另外，气体生产商必须确定钢瓶的密封是彻底防漏的，在指定时间间隔内要进行钢瓶内部检查和流体静力学测试。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。

In slot 2 in your bag put wrapping paper, quantity does not matter in this case.

在你的书包里槽2把包装纸、数量无关紧要。
