Although these combined relative error γ.1%, in order to obtain more precise measurement results, it should be pay attention for the level of the torsion pendulum, the uprightness between the photoelectric doors and the block rod, the location of the being measured substance, the similarity of the shape and the quality between the standard object and the being measured object, human factors and so on.

利用扭摆法测量物体的转动惯量，受到待测物体摆动周期测量误差、装配位置偏移误差和轴线倾斜误差的影响，虽然这些相对误差总合γ。1%，为了使测量结果是加精确，实践中应该注意扭摆的水平、光电门与挡光杆的垂直、待测物重心的位置、人为误差的影响以及待测物与标准件形状、质量的相近性等。

The main content involve the design of the whole project and the frome structare,the design of driving part,the design of the center of grawing,the design of the parts of the machine tool which contain the design of the thread bar,the caculation of the electromotor.

设计共分四章，主要内容有：总体方案与机架的设计；传动方案设计；机床零部件设计，其中包括丝杠和电机的计算；重心计算。

Treatments were as follows: fertilization during leaf-expansion period, fertilization during green-leaf period, and no fertilizer. Results showed that individual leaf area, thousand-leaf weight, and leaf distribution were relatively stable with little influence from fertilization. Fertilization during leaf-expansion compared to the green leaf period significantly increased leaf number, leaf weight per plant, and leaf area index. Fertilization during led-expansion also significantly increased the total weight of leaves corresponding to each branch. The 14th to the 17th branches had the largest number of leaves in the canopy with fertilization increasing the weight of each branch but not changing the center of the canopy.

结果表明：毛竹单叶面积、千叶质量和叶片分布受施肥的影响较小，是较为稳定的指标；展叶期施肥处理（处理1）能显著增加单株立竹的叶片数量，到7月底，其单株立竹叶片总质量和叶面积指数分别比绿叶期施肥（处理2）提高14.8%和13.7%，比不施肥提高27.6%和24.5%；冠层14~17档是单枝叶片数量最多的区域，施肥能增加各枝盘叶片的质量，但对林冠重心的分布无影响；单叶叶面积稳定后（6月），处理1的叶绿素测定值和光合速率显著高于处理2和对照，而处理2与对照间无显著差异。

This procedure is in remote sensing image processing first step in the services within orientation, standard used to determine frame image frame target focus position.

详细说明：本程序是在遥感图象处理中第一步，服务于内定向，用来确定框标图象中框标的重心位置。

In addition, the hip joint moment of unhealthy limbs in frontal plane was 0.12 N-m/kg higher than healthy limbs. At swing phase, knee joint flexion was 7 degrees higher than the unhealthy side and 3 degrees adduction in frontal plane.

摆动期健侧膝关节弯曲角度比患侧多出7度，冠状面上之髋关节内收角度比患侧多出3度；两侧臀中肌作用力患侧明显较小，致使骨盆下垂角度较大，身体重心向患侧偏移。

Simple physics: A static object's center of gravity must be directly above or below the point of suspension, otherwise the object will fall.

简单的物理学：一个静止的物体，其重心一定位于其悬挂点的正上或正下方，否则物体就会倒。

正文：境内当前仅有五钢岀产的飞行发目的轴承用材系国防重心项目用的飞行发目的的二个字号材料。

There are six major parameters impacting vehicle handling and stability performance: the cg location, the rigidity of tyre side list, the rigidity of steering system, the steering system transmission ratio, the rear axle roll steering coefficient and the entire vehicle circling the vertical axis the rotating inertia.

对操稳性影响较大的主要有6个参数：重心位置、车轮侧偏刚度、转向系刚度、转向系传动比、后轴侧倾转向系数及整车绕垂直轴的转动惯量。
