重力

The newton, named after the physicist Isaac Newton, is approximately the force exerted by gravity on an apple at the Earth's surface.

物理单位"牛顿"，是以物理学家伊萨卡牛顿命名的，一牛相当于一颗处于地球表面苹果因重力因素而所受力的大小。

It is well known that the earth tide causes the temporal variations of gravitational field .

精密和详细测定地球重力场及其时间变化，是目前卫星重力测量的主要课题。

In accordance with the delegation's knowledge about the geophysical research work made by ROB and the related materials provided by Belgium,the paper describes the fol- lowing research work of ROB,that is,earth tide and gravity measurements,time determin...

根据访问期间对比利时皇家天文台在地球物理方面所开展的研究工作的了解及比方提供的材料，本文介绍了比利时皇家天文台在地球固体潮和重力测量方面的工作，在时间确定、地球自转的观测与研究和空间大地测量方面的活动，以及在地震学方面的工作，最后还简要地介绍了卢森堡大公国瓦尔弗当日地球动力学地下实验室的情况。

Measurements of physical properties indicate that the rutile-bearing eclogite, due to its very high seismic velocity and density, can produce reflections and gravity anomalies.

岩石物性测定表明，金红石榴辉岩的纵波速度极高，会产生明显的反射与重力异常。

Southeast of the CCSD main hole, there are quite a few such reflectors, implying that eclogite bodies exist in the extension direction of the surface eclogite body.

在CCSD主孔东南方深部重力高部位有多个这样的拱形反射，预示在地表陡倾榴辉岩的延伸方向还有多个一定规模的隐伏榴辉岩体。

This space is a very importantsubject in physics, it is also one of the vacuum solutions of the Einstein equation in thetheory of relativity.

在物理学中有一个猜想：AdS-空间上的经典重力理论与这个空间理想边界上的共形场理论是等价的。E。

Normal gravity equipotential surface is the ellipsoid, which is the standard surface.

正常的重力等位面是椭球面，也就是水准面。

The force of gravity is not constant everywhere for elliptical form and rugged surface of the earth.

由于地球的椭圆形状及其高低不平的表面，重力不是到处都一样的。

Now that we have the emitter we are going to create gravity.

现在有了发生器，我们要创建重力。

The numerical results show that, after the hot intrusion reaches the cold wall, some accumulates in the cold top corner, since the cold boundary layer flow cannot entrain all of the hot intrusion.

结果表明：当热入侵流抵达腔体冷壁后，由于冷壁无法卷入所有的热入侵流，热入侵流在冷上角堆积并产生一个反向流动，在冷壁边界层附近形成一个顺时针涡，该涡在浮力效应驱动下可返回热壁，并在腔体的冷热壁之间形成了腔体尺度的流体振荡，即内重力波。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
