The expression of magnetic moment of an electrified body is similar to that of moment of inertia of a body with various density 摘要带电体定轴转动的磁矩计算与刚体定轴转动的转动惯量相仿，平行轴定理有助于磁矩计算。
The conception of the simple mechanism is that the wheel ' s diameter of car ' s two sides is unequal and the car ' s two shafts are unparallel 这种简单机构的设计思想是不等径轮和非平行轴的机构。小车的内外侧车轮直径不等满足了内外侧车轮的速度比例关系。
The replaceable system model is established through simplifying the complicated parallel axis system . and the practical calculating formula is provided in this paper 摘要该文通过对复杂平行轴系统简化，建立了相当系统模型，并给出了简化后的计算公式，具有很强的实用性。
Xf series parallel shaft helical gear units have the feature of small volume , light weight , heavy transmission torque , steady startup , low consumption , various mounting types and flexible in input and output etc . Xf系列平行轴斜轮减速机具有体积小重量轻传递扭矩大起动平稳低损耗安装方式多样，输入输出灵活等特点。
Then the non - interventional condition is that the relative geodesic curvature is zero . furthermore , for the transmission of the parallel or crossing axles , if the datum surface is the pitch one , the non - interventional condition is naturally satisfied 考虑到平行轴的法向圆弧齿轮传动已臻成熟，论文重点研究了相交轴与交错轴条件下法向圆弧齿轮传动的基本方案。
Gs series high speed involute cylindrical gear box is hard gear side box which is according to national criteria to design and manufacture . its structure form is outside engaged straight fear , oblique tooth gear or herringbone gear of single , closed and parallel axis Gs系列高速渐开线圆柱齿轮箱是按照国际标准设计、生产的硬齿面齿轮箱，其结构形式为外啮合的直齿、斜齿或人字齿结构，单级、闭式、平行轴传动。
So far , the main frame of the conjugation of betrand are established , on the basis of which , it is given that the primary condition the directrix line must be satisfied , the relative curvature of the conjugating surfaces , the relations between non - interventional condition and curvature axle of the directrix line , and so on . the transmission of normal circular - arc gear is a typical bertrand conjugation . in order to promote the transformation from theory to technology , the general principle of this kind of transmission is studied 为了使研究更加贴近于工程，便于解析处理，提出准面的概念，并确立由准面到准线的研究路线，给出了各种传动形式下准面与准线的具体特征，证明了共轭准面上两准线的诱导测地曲率等于零的这一不干涉条件，进而指出，当准面为平行轴和相交轴传动的节曲面时，不干涉条件自然满足。
