自由落体

Galileo used a mercury clepsydra to time his experimental falling bodies.

直到16世纪时，迦利略还用水银漏壶为其自由落体实验计时。

For demonstrating about free fall、horizontal cast、stant cast、the conservation law of mechanical energy、the rule of collision、the formula of Centripetal-Force、simple periodic vibration and the vibration graph.etc.

能完成自由落体、平抛、斜抛、机械能守恒、弹性碰撞、完全非弹性碰撞、向心力、简谐振动、振动图象等高中力学实验。

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。

Drop mode: press performance button ,hammer will fall freely as impact trier.

落锤方式：请按执行按纽，落锤即做自由落体下落冲击试件

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。

METHODS On the basis of the animal model of traumatic DBI caused by free dropping,we measured the water content,the levels of TXB2,6-keto-PGF1α,cAMP and cGMP,and observed the changes of the blood-brain barrier permissibility by the Lanthanum Nitrate labeled electroscope to assess the protective effect of MCPG on the brain tissues after DBI in rats.

在自由落体致DBI模型的基础上，通过测定脑组织含水量、TXB2，6-keto-PGF1α，cAMP，cGMP等水平变化，以及应用硝酸镧标记电镜分析观察血脑屏障的通透性改变，探讨MCPG对DBI的保护作用及其机制。

Descend in free fall under the influence of gravity.

在重力的作用下自由落体。

Faller, who devised an experiment that uses gravity field of a one half metric ton source mass to perturb the trajectory of a free-falling mass.

Faller曾作过一个尝试，他们设计了一个实验，用半顿的重物影响物体自由落体的轨迹。

And then generalized the results of his many experiments into the famous law of free fall .

然后将多次实验结果概括成著名的自由落体定律的人。

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。
