自由落体的

Methods The experimental TBI model was established by bumpiness of free falling body according to Feeney′s.The rats′cerebral edema were imaged with magnetic resonance image,The changes of brain water content and permeability of blood-brain barrier were measured by the methods of wet and dry weight and Evans blue fluorometry.The expression of AQP-4 mRNA was examined by reverse transcriptase polymerase chain reaction.

按照改进的Feeney自由落体撞击法建立大鼠创伤性脑损伤模型，用磁共振成像对大鼠脑水肿进行检测，干/湿比重法和伊文思蓝测定法观察大鼠TBI后不同时相脑组织含水量和BBB通透性的变化，并采用逆转录聚合酶链反应法检测AQP-4 mRNA的表达，蛋白质免疫印迹法检测AQP-4蛋白的表达。

This is how bald eagles prepare to mate -- by locking talons and free-falling like rocks -- which is deeply insane and makes me proud to call the eagle my country's national bird.

这就是秃鹰准备交配的方式--抱成一团，如同那石块一样自由落体--一种疯狂直至的方式，它让我自豪地把鹰称之为我的国家的国鸟。

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。

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。

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。

Considering no other better choice, I followed all his instructions strictly and applied the medicine he provided every day and started the acupuncture treatment. The miracle happened two weeks later since I visited him and had taken five acupunctures: last Friday evening, when I was on a phone call, I felt something dropped all of a sudden from the abdomen. When I saw that sarcoma in an irregular shape and the size roughly of 4cm*3cm*1.5cm, I was frightened a lot, however my instinct told me that this was fibroid.

虽然有些将信将疑，但我还是按照他的吩咐，每天坚持上药，奇迹居然在我作了第五次针灸，也就是到秦医生诊所治疗后的两周以后出现了：上周五晚上，当我正在听电话的时候，下腹突然感觉有什么东西象自由落体一样一下子掉了下来，当看到这个长约4cm，宽约3cm，厚约1.5cm的不规则的肉体时我吓了一大跳，但直觉告诉我这个应该就是肌瘤了。

First, traders pushed up market prices, then push up the overall follow-up steel prices, pushing up the market, inventory costs, and interaction, the formation of steel prices pushed up the momentum, but the final release as a result of excessive steel production capacity, the downstream demand there is no substantial support, resulting in the second half of the last quarter-year of free-falling market prices of steel.

先是贸易商拉高市场价格，随后钢厂跟进推高整体出厂价格，推高市场库存成本，进而相互作用，形成钢材价格的推高的动力，但是最后由于钢厂无节制释放产能，下游需求没有实质性的支持，导致最后一季度下半旬钢材市场价格的自由落体。

These powerful falls have certainly had an effect on thrill seekers especially the free failers jumping off of the gorge bridge.

雄伟壮观的瀑布令那些寻险探奇的人们心驰神往，尤其是那些喜欢从峡谷大桥上纵身跳下的自由落体者。

Impetus theory, which was introduced in order to resolve the problem of projectile, serves as a transitional theory. In trying to explain the motion of freefalling body, Galileo altered his direction of thinking and embraced a new concept of motion according to which motion is instantaneous motion.

为了解决抛体问题而引入的冲力理论是一个过渡，伽利略在用冲力理论解释自由落体运动时改变了思考问题的方向，转向新的运动概念－运动就是瞬时运动。

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。
