重力的

The traditional smoke theory considers that the smoke particles will sedimentate due to gravity after forming of smoke screen, and then the particles reach a final sedimentation velocity thanks to the effect of air-resistance and buoyancy, and the equation can be solved by the Stokes pellet resistance theory and often used to analyze the performance of smoke.

传统烟幕理论认为，在烟幕形成后，烟幕微粒受到重力的作用开始沉降，同时受到空气阻力和浮力的作用，最后使烟幕微粒达到终端沉降速度，这个速度方程可以通过Stokes圆球阻力理论求得，并被用来分析烟幕的性能。

Under Newton's model, gravity was the result of an attractive force between massive objects.

根据牛顿的模型，重力的原因是一个有吸引力的巨大物体之间生效。

Because this extra force is nearly always there (it is a component of the gravitational force on us), we don't notice it.

因为这个额外的力几乎一直保持不变（它是我们所受重力的一个分量），所以我们感觉不到它的存在。

The center of gravity of all objects tends to move downwards.

原来这是由于重力的作用，物体的重心都有向下运动的趋势。

The collapse of a star may produce a White Dwarf or a neutron star — a star, whose matter is so dense that it continually shrinks by the force of its own gravity.

一颗超新星的崩溃可能会产生白矮星或中子星，其物资的密度非常大以至于在其自身重力的作用下持续收缩。

The route of stars in the cluster, moving quickly, may be influenced by the gravity of black wholes.

恒星簇中的恒星快速移动，它们的路径将受到黑洞重力的影响。

Nobody likes to be faced with the obvious signs of aging, stress, sun exposure and gravity in the form of deep creases appearing between the mouth and nose, a jaw line that grows slack and droops, and both fat deposits and folds that appear around the neck area.

没有人愿意面对这个明显的老化，压力，而暴露在阳光和重力的形式，深creases之间出现的嘴和鼻子，下巴线成长疲弱和droops ，并且都发存款和褶皱中出现围绕颈部。

Physics a wave that is hypothesized to propagate gravity and to travel at the speed of light.

被广义相对论所预言的、以光的速度传播重力的波。

However, the elementary unit of gravity – baryon, was never found. Therefore, after half a century of research, physicists were still not united in their view of the universe.

但因为一直找不到重力的物质基础－－重子，以致历经半个世纪的研究，物理界始终对宇宙的认识莫衷一是。

Fly a mass-trail propulsion craft through infinite zero-G space, showoff some spiffy flying and shooting skills.

飞大众径推进工艺，通过无限的零重力的空间， showoff一些spiffy飞行和射击技能。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
