Under the precondition of above analyses, this research compares the meteorite-stricken cases in planets and secondary planets of solar system, the "shielding" and "eroding" effect in aerosphere, the scale of small planets and movement rules, then briefly analyzes the basic reason of mass meteorite-stricken events occurred in earth history.

在上述分析的前提下，本研究从太阳系有关行星和卫星表面陨击现象对比，大气层的"遮蔽"和"侵蚀"作用，小行星的规模及运动规律等方面简要分析了地球历史上大规模陨击事件发生的基本原因。

In addition, depending on the method of numerical simulation and theoretical analyses, some kinematic and geometric features of 0° involute—enveloping worm gear drive, such as meshing surface, first—type limit, second —type limit, worm surface, the numerical representation of contact line and bearing contact, are systematically studied. These relevant conclusions provide an important basis for the design and manufacture of new type worm gear set. As we predict, the method of numerical simulation has special effect in solving the question of complex conjugate surface.

综合利用仿真方法与解析手段，对0°渐开线包络蜗杆传动的啮合面、一类界限、蜗杆齿面构成、仿真接触线及仿真接触域等运动几何学特性进行了系统研究，有关结论为此种新型蜗杆副的设计与加工提供了重要基础，并且显示出数字仿真方法在研究复杂共轭曲面问题时所具有的特殊功效。

In Dateline USA, we'll hear about a growing movement called Slow Food.

在今天的"美国报道"中，我们将听到的内容是有关一种正在兴起的"慢餐"运动。

Bloodless and many footed animals, whether furnished with wings or feet, move with more than four points of motion; as, for instance, the dayfly moves with four feet and four wings: and, I may observe in passing, this creature is exceptional not only in regard to the duration of its existence, whence it receives its name, but also because though a quadruped it has wings also.

无血多足动物，不管装备翅膀还是足，移动依靠多于四个的运动点：像是，例如，蜉蝣依靠四足和四翅膀活动：并且，我可以顺便说一下，这种生物的特别不仅与它的生存周期、名称的由来有关，也因为它尽管是四足动物，但是也有翅膀。

Some preliminary suggestions have been made on some problems involved in the design andmanufacture of multi friction disk stepless speed change device .

本文仅就多摩擦盘无级调速器的运动设计、传动分析和关键件的选材、加工和装配等问题，提出粗浅看法，供有关设计和生产部门参考。

Starting at aloutstanding the differerent time were the international arousements to the lefts of woman.

几乎与此同时开端的是有关妇女权益的全地球运动。

To a big extent, it strongly relates to my physical condition, so I myself set a routine: Breakfast and walk to the office in the morning is a must. Use the stair to the office after lunch is a must, Only take vegetable for dinner and half hour practice afterwards is a must, it could be Huala ring, jumping rope, badminton or even walking.

这在很大程度上和我的身体状况有关，所以自己给自己了一个任务，早上一定要吃早饭，一定走路上班，中午吃饭后坚持走楼梯，晚上只吃些菜不吃饭，然后就是半个小时的运动，或是哗啦圈或是跳绳或是打羽毛球或是散步。

Entropy can be described by power-law function of kurtosis, which implies there can be some relationship between structures and extrema in time series.

垂直速度与保守量的非线性相关部分与垂直于气流的水平运动有关。

The estimation of Time to Collision related to avoiding collisions or making interceptions is an important cognitive ability for individuals.

中文摘要对运动物体碰撞时间的估计是个体重要的认知能力，与避免碰撞和进行拦截等行为有关。

According to the National Earthquake Information Service of the US Geological Survey, earthquakes have gradually increased from 1 severe quake between 1890 and 1899 to 765 from 2000-2004. Could this be due to our solar systems movement towards this Galactic Equator?

根据美国地质勘探局的国家地震信息服务中心提供的信息，1890年至1899年间，地球只发生1次强烈地震，而2000年至2004年，地球却发生了765次强烈地震，强震次数不断增加是否与太阳系向银道运动有关？

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
