The procedure can be used to optimize the single resource looped network with pump station and gravity.

算例表明这一方法是可行的，可用于单水源泵站加压管网和重力管网的优化设计。

The reason of macrosegregation elimination is that the primary phase is affected by the combined effect of gravity, buoyancy and Lorentz force.

宏观偏析的消除是由于初生相同时受到重力、浮力和Lorentz力的合力作用的结果。

Robert Hooke, Isaac Newton's low-born rival who came up with insights about gravity that Newton may have stolen, first applied the microscope to them.

出身低微，首先提出牛顿重力理论的罗伯特。胡克最先用显微镜来观察雪花。

The high accuracy inter-satellite ranging system is the major payload of gravity exploring satellite using satellite to satellite tracking in low-low model.

高精度星间测距系统是低低卫卫跟踪重力卫星的关键有效载荷。

The observational equations have been derived using the three methods above which are based on high-low SST and low-low SST observational data respectively, at the same time, the shortages and merits of these three methods are analyzed. 3The problem of gravity field recovery can be attributed to the solution of over determined system of equations.

本文分别以高低卫卫跟踪和低低卫卫跟踪观测数据为基础，导出了基于上述三种方法的观测方程，并分析了它们的优缺点。3重力场恢复最终归结为超定线性方程组的求解问题。

In the low-low satellite to satellite gravity mission, the intersatellite range and range-rate data are the observable values, while the intersatellite acceleration can be derived from the range-rate through digital differential. Using acceleration data, people can avoid solving the variation equations of the satellite motion and simplify the observation equations. But on the other side, the digital differential will amplify the observation noises and finally affect the solved geopotential accuracy.

低低卫星跟踪卫星的观测量是两低轨卫星的星间距离或星间速度，星间加速度由星间速度通过数值微分导出，用星间加速度作为观测量可以避免解算卫星运动的变分方程，简化观测方程的建立，但数值微分会使观测噪声放大，从而影响重力位的解算精度。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
