Information from the Apollo missions hasled some investigators to favor a warm ancient Moon (Smith et al., 1970; Wood,1972). This idea has been most recently amplified by Wood (1975) and Walker et al.(1975) who suggest that the petrology of the ancient anorthositic lunar crustcan be explained as having resulted from crystal fractionation and gravitational separation in a well-stirred global subcrustal magma chamber referredto by Wood (1975) as a magma ocean.

根据阿波罗任务的信息，部分调研者对早期月球是温暖熔融的青睐有加（参见1970年史密斯团队报告稿和1972的伍德报告）。1975年，伍德和沃克团队进一步加强了这个观点，他们推测：古老月球曾经是熔融的，充分对流、搅拌的全球性岩浆海洋中的重力分离和结晶分异过程能够解释辉长岩月壳的来历。

When the spaceship returned to start procedures to return module down to 15 km away from the ground, it was the pneumatic resistance attack it suffered gravity, a drop from supersonic speed reduced to subsonic and stability in the 200 米/秒 about time to slow down on the parachute on.

当飞船启动返回程序，返回舱下降到距地面15公里时，它所受到的气动阻力近似于它所受的重力，下降速度由超音速减到亚音速，并稳定在200米／秒左右，这时再减速就要靠降落伞了。

In particular, they have wondered why the giant clouds, which can span thousands of light-years in diameter, don't just collapse completely into supergiant stars, crunched together by gravity's inexorable pull.

特别是，他们想知道为什么大云，它可以跨越数千光年的直径来，不只是崩溃到超巨星完全合并在一起重力的必然拉动。

The result indicates that viscosity of MAP suspension will become lower as temperature becoming higher.

结果表明，随着温度的升高，磷铵料浆粘度降低，料浆重力沉降速度增大。

Since the body fluid will lose its weight when a space man enters low gravity environment, his head will be swelled in a few minutes.

太空人進入低重力環境時，體內液體失去重量，幾分鐘之內，他的頭就會開始膨脹。

So called reservoir is physical or mathematical; for a physical system, the mathematical model is a system of partial differential equations with related initial and boundary value conditions, it can describe important physical process occurring in the system, for example, the process occurring in reservoir, which mainly concludes flow of fluids and transportation of mass, gravity、 viscosity、compressibility have effect to it; differential equations describing this process are obtained by combining Darcy law of every phase and its mass equilibrium in differential form.

这种模型是物理的或数学的；一个物理系统的数学模型，是偏微分方程组和适当的一组初、边值条件的总体，它能够描述在系统中发生的重要的物理过程，比如在油藏中发生的过程，主要是流体的流动和质量的转移，重力、粘滞力、压缩性等在流体流动过程中都是起作用的；描述这个过程的微分方程是由将各相达西定律和各该相的微分形式的物质守恒相结合而得到的。

The horizontal north vector is tangent to the earth and hence the rotation is the result of earth curvature.

由于地球旋转而引起的离心力随纬度θ到地轴距离的变化而变化以及由极向扁率引起的地球半径的变化而对重力资料进行的校正。

The rate of excellent and good clinical results was 83.3％. Mild forefoot adduction was left in 2 feet of 2 cases and quite obvious tarsal articular ankylosis was found in 4 feet of 4 cases; however, there were no significant differences of gait and load bearing between these patients and normal children.

有2例2足遗留轻度前足内收畸形，4例4足有较明显的跗骨间关节僵硬，但其步态和负重力线均与正常儿童无明显差别。
