自由落体

Although this experiment by the free-falling 30 meters to simulate the "high-speed" campaign, but is still in the inertial reference frame completed, the conclusion of "not slowing down" from a psychological point of Einstein's theory of relativity proved the first assumptions.

虽然这个实验通过30米的自由落体来模拟"高速"运动，但仍然是在惯性参照系中完成的，因此实验的结论"不会变慢"从心理学角度验证了爱因斯坦相对论的第一个假设。

Methods A weight drop device was made to establish a model of TBI in rat. Vital signs and pathological changes were observed. The changes of function were scored by a functional scale provided by us.

应用自行设计制造的自由落体撞击装置建立大鼠创伤性脑损伤模型，观察大鼠脑损伤后生命体征和病理学改变，并通过自行设计的神经功能量表进行功能评分。

Gene Sperling tried to goad me into trying it, but I told him I'd had about all the free falls I could stand.

吉恩·斯珀林也想煽动我尝试一下，但我告诉他，我已经经历过能承受的所有自由落体运动了。

He personally experiment to determine the law of free-fall and found that: The object of the law of inertia, a reasonable law, such as when the pendulum vibration, the law of Motion put forward a campaigns of the principle of relativity, but also on the speed, acceleration and so on kinematics The basic concept of making a strict definition.

他通过亲自实验，确定了自由落体定律，发现：物体的惯性定律、合理定律、单摆振动的等时性、抛体运动规律，提出了运动的相对性原理，还对速度、加速度等运动学的基本概念做出了严格的定义。

In Collisions in Free-fall, Lewin dons hiking shorts, a pith helmet, and sunglasses to conduct a projectile experiment by firing a ball at a monkey suspended from a pole.

在"自由落体中的碰撞"中，列文穿着旅行短裤，戴着木髓制的太阳帽和墨镜做一个抛物线实验。他点燃在打桩落锤的一个支撑点上搁置的一个小球。

Riding on the trend of the 400th anniversary of Kepler's telescoping the universe, NSC, combining astronomic, historical, literary and technological materials, presents a special exhibition "400 Years of Heaven Gazing," applying advanced techniques to fly the participants to the beautiful endless universe. Exhibits such as the juxtaposition of Kengting, Lulin and Hawaii etc. four observatories' realtime images and 3D movies such as Galileo's Free Fall experiment at Leaning Tower of Pisa and the Mystery of Saturn etc. altogether enrich the Spectacularity.

配合全球天文年及纪念伽利略运用天文望远镜仰观宇宙四百年，国科会融合天文、历史、文学和科技等元素，举办「2009科学季：仰观苍穹四百年」特展，不但藉由新颖的科技技术，要使民众进入展场，如同置身於浩瀚美丽的宇宙，而且还呈现垦丁、鹿林及夏威夷等四地天文台观测的即时影像画面，以及包括伽利略大小球的比萨斜塔自由落体实验和土星之谜的3D立体电影院等等，都更增添特展的可看性。

The entry was more of a free-fall, really, Lron's piloting veering between the suicidally reckless and the professionally competent.

进入大气的过程，更像是自由落体。勒荣操纵舵轮时介乎自杀性的草率和专业性的胜任之间。

I believe they call it,uh,terminal velocity.

我想这就是所谓的。。。自由落体速度

The two underwing stations could carry two PL-5 IR guided AAMs, unguided rocket pods or free-fall bombs.

二个机翼下挂点可以携带二枚PL-5 IR制导AAM、非制导火箭吊舱或自由落体炸弹。

Methods①The animal model of braincontusion caused by free drop hammer was established.②The injuredtissue of rat brain were stained by TUNEL for apoptosis,immunohistochemistry for Caspase-3 and Feulgen"s for DNA. Image analysistechnique and the statistical method were employed to explorate thetemporal changes of injury time.③The DNA was extracted from ratcontusive tissue of brain and assayed by gel electrophoresis toinvestigate the relationship between the DNA fragmentation and injurytime.④One handred and seventeen cases of death from traumatic braininjury were retrospective researched to investigate the characteristicof TBI in forensic medicine.⑤The contusive tissue of human brain werestained by TUNEL, Caspase-3 immunohistochemistry and Feulgen"s methodsin the same way to analyze and disclose the linear relationship betweentemporal changes with injury time.

方法①建立大鼠自由落体打击脑损伤模型；②对不同损伤时间组的大鼠脑挫伤组织进行TUNEL、Caspase-3免疫组化、Feulgen's DNA染色，结合图像分析技术和统计学分析，探讨脑挫伤后神经细胞凋亡、DNA片段化和含量的时序性变化；③提取大鼠脑挫伤组织DNA进行琼脂糖凝胶电泳分析，观察DNA片段化随损伤时间的变化特点；④对117例颅脑损伤致死案例进行回顾性分析，探讨其法医学特点；⑤选择不同损伤时间的人脑挫伤组织同样进行TUNEL、Caspase-3免疫组化、Feulgen's DNA染色和分析，观察上述指标与损伤时间的关系。

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。
