The results show that the zero speed point is located on the arc between two absolute speed zero points of rotation axes, and the necessity of relative speed zero point is demonstrated, From the location of speed zero point, some useful conclusions can be drawn.

对速度零点的位置进行了分析，得出了如下结论：对于一定形状的工件，通过调整两轴的转速比以及两轴夹角参数，可以将速度零点置于工件之外，从而避免速度零点对研磨的不利影响。

Approach: the surface rust with sandpaper lighting, using raw materials with after winding into ring for emergency action to deal with, the best method is for-axis, or axis setting processing sets to restore the size of the original axis.

处理办法：锈蚀表面用砂纸打光，用生料带缠绕后，放入动环作应急处理，最好的方法是换轴，或轴镶套后加工恢复到原轴的尺寸。

Use wear ring to hold shaft and increase moving stability to confirm shaft and rim of cylinder is un-contact and un-scraped.

以耐磨环支撑出力轴，加强出力轴移动稳定性，确保出力轴与油缸壁不接触、不刮伤。

It is widely concerned in fatigue of concrete structures. In this paper, concrete triaxial compression fatigue experiments and tension-compression fatigue experiments with constant confinements in two lateral directions have been carried out using a self-modified loading apparatus. Based on the analysis of the test data, the quantitative principles of concrete fatigue deformation and the calculation method of fatigue strength are determined.

混凝土结构的疲劳是一个广为关注的问题，本文针对这一问题结合国家自然科学基金项目——混凝土多轴变幅疲劳破坏准则(50078010)的研究，利用自制的试验加载装置完成了两向定侧压约束下混凝土三轴受压、三轴拉-压等幅和变幅疲劳试验，对试验结果进行了分析。

The drive unit includes a drive shaft (3), which is arranged to carry the centrifuge rotor (2) and is rotatably journalled in at least one bearing member (4, 5), and a casing (6), which delimits an upper space (7), in which the drive shaft and the bearing member are located and a lower space (8) for storing oil.

该驱动组件包括一驱动轴(3)，用来支承离心转子(2)，并以轴颈可转动地支承在至少一个轴承件(4、5)内；一个壳体(6)，它界定一上部空间(7)和一下部空间(8)，驱动轴和轴承件配置在上部空间内，下部空间供贮盛润滑油用。

Equivalent imperfections are provided, which can be used directly as an eccentricity of the axial force in calculating the design moment It is permissible to construct simply a linearised version of the interaction diagram for cross-sectional resistance to combinations of axial compression and uniaxial bending moment on a composite section.

登录 |阻力的屈曲由于不完善的减少可能是取自EC3系列屈曲曲线。等效缺陷提供，它可以用来作为计算的轴向力设计的时刻直接偏心这是允许的构造简单组合截面上的一个横截面的抗轴向压缩和单轴弯矩组合交互图线性化版本。

Flying wing center column locking knob Flying wing design of center column locking knob,which can adjust the height of center column more laborsaving and more convenient.

飞翼形中轴锁紧钮中轴锁紧钮的飞翼形设计，可更省力更方便的调节中轴高度。

What this means is that the two axes of language, the syntagmatic (at the level of the generated sentence) and the paradigmatic can be read as operating together in a discourse.

这意味着语言的两个轴，组合轴和聚合轴能够被理解为在某个话语中是可操作的。

In this paper, the basic mathematical model was derived by means of two methods, the first is the twostar positioning algorithm in celestial navigation theory and the second is based on the gyro dynamics theory. The results from these two methods are identical and therefore are correct. The latitude is equal to the elevation-angle of the polar gyro. The course is the ideal output from the sensor fitted to the outer gimbal. The longitude is a function of the equator gyro's azimuth and elevation angles.

本论文用天文导航中的双星定位法和经典的陀螺力学原理两种方法建立了ESGM的基本数学模型，并且得到一致的结果，说明所建模型是正确的，即载体的纬度等于极轴陀螺主轴相对水平面的高度角，载体的航向等于极轴陀螺外环轴上角度传感器的理想输出，载体的经度是赤道陀螺的方位角和高度角的函数。

BACKGROUND: The HOX gene family is a highly conserved transcription factor family, which affects the formation of basic axis and secondary axis during embryonic development, at the same time, it plays a pivotal role in the development of the central nervous system, axial skeleton, stomach intestine, urogenital system and external genitalia.

背景：HOX基因家族是一个高度保守的转录因子家族，该家族在胚胎发育阶段基本体轴和次级体轴的形成中起作用，同时在中枢神经系统、中轴骨、胃肠和泌尿生殖系及外生殖器和肢体的发育中起重要作用。
