自由落体的

The instrument for measuring acceleration of gravity is redesigned.

1引言目前，测量重力加速度的方法有单摆法和自由落体法。

Pascal French scientists found that the pressure of liquids and gases in the dissemination of law; British scientists found that gas pressure Boyle's law.

物理学 伽利略通过多次实验发现了自由落体、抛物体和振摆三大定律，使人对宇宙有了新的认识。

Objective To compare the contusion and fluid percussion brain injury model in rats.

目的 比较自由落体和液压致大鼠脑损伤模型的异同。

This is written by TC a round of free-fall of the drawing program.

详细说明：这是用TC写的一个圆的自由落体的绘图程序。

To study the effect of ectogenesis progestogen progesterone on peripheral edema and neurocyte apoptosis in rats following cerebral cortex injury induced by free fall.

探讨外源性孕激素黄体酮对自由落体脑损伤模型大鼠大脑皮质损伤后周围水肿及神经细胞凋亡的治疗作用。

Descend in free fall under the influence of gravity.

在重力的作用下自由落体。

American skin blame a research that the research center publishs 16 days this month shows as a result, include media of newspaper, magazine, network, TV and broadcasting station inside course of study of medium of whole United States is in at present " adjacent and free falling body " quicksand, among them daily and weekly particularly serious.

美国皮尤研究中心本月16日公布的一项研究结果显示，包括报纸、杂志、网络媒体、电视和电台在内的整个美国传媒业目前处于"接近自由落体"的危险状态，其中日报和周刊尤为严重。

A strip block is used instead of the ball to eliminate the measurement error caused by the trajectory deviation of the ball when passing the photo gate.And a spring clip is used to replace the electromagnet to eliminate the effect of remanence.

在单摆法中，要求忽视细线的质量且线长及小球尺度相比很大，把小球看成质点，并且小球的摆幅不能超过5°[1~3]；在自由落体法中，一般是用小球作为自由落体，但小球通过光电门时，往往不是小球的质心遮光计时，另外，钢球是用电磁铁通电后吸住的，由于断电的瞬间，电磁铁有剩磁，钢球不立即下落，并且钢球应吸在电磁铁的中心处，这些因素都会影响重力加速度的测量。

Editor this segment Culture, Galileo's free fallers experiment Legend, was born in 1590 Pisa's Italian physicist Galileo, once in Pisa in free fall, two experiments of different weights from the same height and ball down, the ball at the same time, two of free fall, and found that the overthrow Aristotle first heavy objects will reach the ground with its head, the speed is proportional to the mass of the view.

编辑本段文化伽利略的自由落体实验传说1590年，出生在比萨城的意大利物理学家伽利略，曾在比萨斜塔上做自由落体实验，将两个重量不同的球体从相同的高度同时扔下，结果两个铅球同时落地，由此发现了自由落体定律，推翻了此前亚里士多德认为的重的物体会先到达地面，落体的速度同它的质量成正比的观点。

The methods testing the WEP usually are torsion pendulum and free falling, the latter one is limited by the height of experiment, so the sensitivity of this method can't be improved, thus nowadays the torsion pendulum is mostly used in high sensitivity experiment.

检验弱等效原理的方法多为扭秤方案和自由落体方案，自由落体法由于受到实验高度的限制，使得在地球上的实验精度无法得到进一步提高，因此现在高精度的地面实验大都采用扭秤方案。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
