We also include the distributions of surface tension,gravitational acceleration,and viscosity to the whole flowing procedure in dynamicfluid equations.

数值例子中，我们不仅捕捉到了分界面在运动过程中的拓扑改变，如从多连通变为单连通，再分裂为多连通等，分界面的扭曲、合并、形成射流等大变形，还在流体力学方程组中添加了反映分界面性质的表面张力、重力、粘性项。

Systematic study is carried out to the main factors that influence the levitation stability during containerless processing of materials. The effect of the medium density r f , sound speed c , gravitational acceleration g , and resonant states Hm on the acoustic containerless processing is revealed.

对材料声悬浮无容器处理过程中，影响悬浮稳定性的主要因素进行了深入研究，揭示了媒质密度 r f ，声速 c ，重力加速度 g 和声场谐振状态 Hm 对声悬浮过程的影响机制。

Similarities in morphology, element ingredient and element content between lagenal otoliths and utricular otoliths suggest that the two types of otolithic organs may play similar roles in sensing gravitational and acceleration signals.

信鸽瓶状囊的耳石与椭圆囊的耳石在形态、元素组成及含量水平上具有相似性，提示这两种耳石器官可能在感受重力和加速度信号中共同起作用。

Among these forces is the neglect of vertical forces which is not too serious because they are quite small compared with the earth's gravitational attraction.

在这些力中，垂直力受到忽视，但因为它们与地球的重力相比微不足道，所以这不是一个十分严峻的问题。

Is it mgh, where m is your mass, g is gravitational constant and h is the height of the stairs?

陶瓷醒悟了："是不是 mgh？m 是你的质量，g 是重力常数，h 是楼梯的高度？"

The gravitational force is the same so is the mass of the paper.

The results show that the gravitational force and the strong particle-particle interaction have significant effects on concentration distribution and velocity distribution profile.

结果表明：重力因素及不同颗粒相间的相互作用是影响颗粒相管内浓度分布和速度分布的根本原因。

Any changes detected in their orbits correspond to gravitational anomalies and thus mass distributions inside the planet.

在他们的轨道上所发现的任何变化，在行星内部符合重力异常和质量分布。

The gravitational force on a mass in the meter is balanced by a spring arrangement, and a third force is provided which acts when the system is not in equilibrium.

重力仪本身质量引起的重力可通过弹簧布罩来平衡，且当系统处于不平衡状态时，系统提供的第三种力将会起作用。

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%.
