Firstly, a new design method of cam profile has been developed by using finite terms of Fourier Series in the cycle of cam angle as the basic equation of cam profile, so the difficulty of base circle wave existing in the method of resonant cam design can be eliminated. On the other hand, the method proceeds from the acceleration of cam profile, which makes the acceleration not only smooth and continuous, but also easy to be controlled, and the cam profile with good performance can easily be acquired.

此方法用以凸轮包角为周期的富立叶级数有限项作为凸轮型线的基函数，可以免去谐波凸轮设计时控制基圆波动的困难；此方法又是从凸轮型线的加速度曲线入手进行设计，使型线加速度不但光滑、连续，而且形状容易控制，便于设计出动力性能优良的凸轮型线。

Then the scattering waves are represented bythe series of Bessel functions expansions.

它是用一个半径足够大的大圆弧拟合半空间表面，再将所有的散射波展开成Fourier-Bessel级数的形式。

In this paper, the method of using Volterra series expansion to analyze the linearity of high frequency CMOS transconductance stage with source degeneration resistor is provided. In order to reduce the complexity of the analysis, the transconductance stage is treated as cascade connection of two nonlinear systems. The IIP3 (input referred third-order intercept point) of the transconductance stage is calculated.

In the case of continuous operation, the consumption of enzyme, conversion and cost with different number of reaction stages were examined.

对于批式反应，计算了不同浓度底物的水解过程和各种抑制因子对反应过程的影响；对于连续反应，计算了不同级数下的需酶量、转化率和成本消耗。

When handling the problem of mapping accuracy, the convex-concave expansion technology for Taylor series expansion is adopted.

根据复变函数共形映射理论，讨论Schwarz-Christoffel积分变换的正反求解过程；应用Taylor级数凸凹分级展开技术，处理映射精度问题。

If the fluid flow separated from the sharp edge of the rearward steps reattached in the effective region, the reseparated point would occur downstream of the cross section of the cylinder and the drag would be reduced.

对再附流动的有限级数解表明，由有效再附区开始的再附边界层能够保持其边界层状态，发展至柱面最大迎流截面之后的流动再分离点。

Because the curve radius of easement curve gradually changes, the formula for calculating the coordinates can not be obtained with the method of integration.

由于缓和曲线的曲率半径是逐渐变化的，不能用积分的方法求得其上点位坐标的计算公式，以往都是用级数展开进行近似计算。

Again, harmony vocals – Beatle-esque ones, in this instance – help set the mood, and an ascending chord progression led by Morse spreads its arms heavenward, eventually settling into a circular pattern that becomes one of the more moving codas not just in Purple history, but, yep, in the history of heavy rock itself.

再次，和谐的人声-披头四成员非常霸道，在这一点上-协助成立的情绪，以及一个升序弦级数率领摩士利差其武器出口天地，最终沉淀到一个循环模式成为一个较为动c o das不仅在紫色历史，而且， yep ，在历史上的重摇滚本身。
