不等于

Through transformation of parameters, the meshing design system among Hy-Vo silent chain, sprocket and hob was built up based on the research of the pitch increment and the equivalent apothem increment of the effects on the common normal line length when the Hy-Vo silent chain was wrapped around and located on the sprocket, with the proper meshing conditions of Hy-Vo silent chain and sprocket into consideration. The design method of common normal line length was put forward that can be used when the value of the sprocket pressure angle was equal or unequal to the value of the Hy-Vo chain plate pressure angle.

在分析Hy-Vo齿形链链节围在链轮轮齿上定位时其节距增量和当量边心距增量对链轮公法线长度影响的基础上，根据Hy-Vo齿形链与链轮的正确啮合条件，通过参数变化，建立了Hy-Vo齿形链－链轮－滚刀三者之间的啮合设计体系，提出了既适用于链板齿形角等于链轮压力角情况，也适用于链板齿形角不等于链轮压力角情况的Hy-Vo齿形链链轮公法线长度的计算方法。

All-round development is not characterless development, either, nor should it deny personality.

全面发展不等于平均发展，不等于不要个性。

The basic steps of this method are as follows.The firststep is to derive a necessary condition such that the families of quasipolynomials withone parameter,corresponding to the edges of the polytope,have pure imaginary rootsby using the Dixon's resultant for polynomials.Then to check that the casescorresponding to the parameters obtained in the first step are in fact impossible byusing the generalized Sturm criterion and some stability criteria.

其基本思路是先利用多项式方程组的Dixon结式理论导出使各棱边对应的单参数特征拟多项式有纯虚根时，参数值应满足的一个等式条件，即所谓的Dixon结式等于零，然后由广义Sturm判别法验证对所有参数值，Dixon结式不等于零，或使结式等于零的解不产生特征拟多项式的纯虚根。

Forbearance is no quittance .

不催帐不等于取消帐；缓期不等于作罢。

Omittance is no quittance .

Actuality are not. The discrepancy, which is about a quarter of a semitone and is known as the Pythagorean

在具体运用五度音程的循环时，12个五度音程从理论上讲应等于7个八度，但实际上不等于这个音差为半音的1／4，称为毕达哥拉斯音差。

" In the application of the cycle of fifths, 12 fifths are equal to 7 octave s in theory, but in actuality are not. The discrepancy, which is about a quarter of a semitone and is known as the Pythagorean comma,"
