The first and second derivatives of the coordinates of a cam profile are calculated using numerical differentiation method,and substituted with curvature radius formulas in calculus,thus obtaining its curvature radius.

应用数值微分法计算凸轮廓线坐标的一、二阶导数，代入微积分学中曲率半径公式，即得凸轮廓线的曲率半径。

The local heat transfer coefficients on the concace, convex and plane wall of a duct have a mild difference, with the heat transfer coefficent of concave surface being the largest and that of the convex surface the lowerest.

同一通道中凸、凹表面的局部换热系数有一定程度的差别。凸面的换热优于平面，后者又大于凹面。

Some convergence results of the gradient projection method under milder conditions are obtained.

进一步给出了目标函数f是凸函数和拟凸函数时的更强的收敛性结果。

We first provethe Bergman completeness for several class of non-smooth pseudoconvex domains.

我们首先证明了几类非光滑边界拟凸域的Bergman完备性；接着，我们研究超凸域上的Bergman度量。

Moreover, based on the symmetric Rouche's theorem, a necessary and sufficient condition for the Hurwitz stability of the convex combinations of polynomials is proposed. This condition is simple and can be easily applied to the Hurwitz stability analysis of the convex combinations of polynomials.

而且基于对称Rouche定理给出了多项式凸组合Hurwitz稳定的一个充要条件，该充要条件直观简明，用于分析多项式凸组合的Hurwitz稳定性十分方便。

We avoid of assuming that the interior of the ordering cone is not empty and the cone has a compact base or a weakly compact base, but consider Benson proper efficiency in the framework of sparable locally convex metric spaces.

本文回避了以往需要序锥内部非空并且有紧基或弱紧基的条件，转而把目光从局部凸拓扑向量空间投向可分局部凸距离空间，在这个框架下，先利用Polarity定理给出了Benson真有效点的标量化定理。

A larger preoperative thoracic kyphosis angle, greater immediate postoperative thoracic kyphosis angle decrease, thoracoplasty, and male sex correlated significantly with PJK.

一个更大的术前胸椎后凸角、更明显的术后胸椎后凸角减少、施行了胸廓成形术和男性等矫正因素与PJK显著相关。

This chapter is dedicated to the study of the properties of close-to-convex univalent harmonic mappings.

在这一章中，我们主要研究了单叶调和映照的近于凸子族，首先给出了近于凸单叶调和映照与正实部解析函数之间的一个关系。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
