顺

To shift clockwise in direction, as from north to northeast.

顺转：以顺时针方向变化，如从北向东北。

If the sign is positive then the polygon vertices are ordered counter clockwise about the normal, otherwise clockwise.

如果这个标志是积极的，然后对多边形顶点下令对正常的、反顺时针方向旋转，否则顺时针。

The number and size of flow jets can be varied to optimize the creation of a mixing vortex, and the direction angle can be varied in the same manner, and/or optimized for Coriolis efficiency (counter clockwise in the Northern Hemisphere, and clockwise in the Southern Hemisphere).

的数量和规模的流动战斗机可以多种多样，优化建立一个混合涡和方向不同的角度可以以同样的方式，和/或优化的科里奥利效率（反顺时针在北半球，并顺时针方向的南半球）。

A new curvature-based algorithm in free-form curve fitting was proposed to fit a 2D NURBS profile with an arc spline ,where a new form of curvature formula with matrix representation was also proposed,and then the arc spline tool path with G~(1) continuity was generated.

给出了一种平面曲线轮廓的圆弧样条拟合及刀具路径生成算法，该算法面向零件轮廓的光顺性刀具路径生成，通过应用曲线的曲率关系，对以NURBS表示的被拟合自由曲线按参数递增的方向用G1连续的圆弧或直线段逐段拟合，并生成相应的圆弧样条刀具路径，从而实现零件曲线轮廓表面的光顺加工。

Mesh fairness problem We propose the conception of discrete curvature vector for meshes, and suggest a new fairness criterion that a mesh is fair if changes in discrete curvature vectors of this mesh are gradual and uniform Based on this fairness criterion, two algorithms are presented.

网格的光顺问题本文提出了离散曲率向量的概念，并以其变化平稳均匀作为网格光顺的准则，这一准则兼顾了曲率大小及法向的变化。

The discrete curvature vector based method to fair mesh by modifying vertex positions We first low-pass filter the discrete curvature vector function to make it change more gradually and uniformly, and then modify the vertex positions according the resulted function to improve the fairness of mesh.

以此为基础，给出了两个算法：网格改点光顺的离散曲率向量法基本思想是先用低通滤波算子修匀曲率向量，并由此修改顶点的位置以改善网格的光顺性。具体算法吸取了优化问题中Zoutendijk可行方向法的基本思想。

By the methods of DFT,6-311Gand 6-311+Gbasis set,we optimized the geometry conformation of the neutral moleculesor ions of cyclopropane,cyclobutane,cyclopentane,cyclohexane,also calculatedthe frequency of these species.

顺磁共振实验也叫电子顺磁共振或电子共振或电子磁共振，是检测自由基的一个最灵敏、最直接的方法。

objective:to study the effect of tuting oral liquid on treating cisplatin-induced pigeon'vomiting.methods:the animal model was designed by injecting the chemical medicine cisplatin in pigeon's abdomen, vomiting reaction was observed by the vomiting times and delitescence.

目的：观察吐停口服液对顺铂所致家鸽呕吐的作用。方法：采用家鸽腹腔注射顺铂法制造呕吐模型，观察家鸽呕吐次数、呕吐潜伏期。

Magnetic properties of a series of Cd1-xMnxSe quantum dots with different sizes and Mn concentrations were measured by using superconducting quantum interference device magnetometer. The field dependent magnetization of the Cd1-xMnxSe quantum dots at 2 K was obtained and it was identified not to be dominated by CdSe quantum dots but Mn ions.

我们利用超导量子干涉仪量测不同尺度(D = 5 nm， 8 nm)及不同Mn浓度(x = 0.375%， 0.75%， 1.5%)的Cd1-xMnxSe奈米颗粒磁性；我们推测在温度2 K下，所量测的磁化强度是由Mn原子贡献而非来自奈米颗粒，拟合其磁化强度对磁场曲线图而得出样品中Mn原子个数，同时假设Mn离子的磁性行为高达室温仍满足Brillouin function和Curie顺磁定律，所以可从高温的数据扣除Mn的顺磁贡献。

The results show that there is a linear correlation between magnetic susceptibility and density. Take 1.6 g/cm^3 as a boundary value, the magnetism of high density coal and low density coal was opposite. The diamagnetism property of low density coal weakens and the paramagnetism of high density coal enhances along with the size reduction of fine coal. The magnetic field intensity influences the magnetism of coal.

研究表明：比磁化率同密度间存在线性相关关系，以1.6 g/立方公分为界，高、低密度级煤分别呈顺磁性和逆磁性，且随煤粉粒度的减小，低密度级煤的逆磁性减弱，而高密度级煤的顺磁性增强；磁场强度对煤的磁性有一定影响。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
