Here we describe mobile robot model and desired path in polar coordinate and determine reference points with polar angle. The controller is designed based on backstepping approach.

本文在极坐标内描述移动机器人模型和期望路径，以极角为参数确定期望参考点，控制器采用后退方法设计。

Sort-and-Incremental Algorithm Definition of h-plane's polar angle:' for h-plane like x-y≥constant, we ≥ define its polar angle to π.

半平面的极角定义：比如x-y≥半平面的极角定义比如≥常数的半平定义它的极角为π。

For a peptide to act as part of the host defense system or to be of pharmaceutical interest, high antimicrobial activity must be combined by low hemolytic activity. Our results indicated that the antimicrobial activity increased with increasing charge and polar angle, with charge of ＋4 and polar angle of 140° exhibiting the highest antibacterial and membrane permeabilizing activity. Higher hydrophobicity and hydrophobic moment correlated with increased hemolytic activity, thus decreasing selectivity dramatically.

胜肽要扮演宿主免疫机制的一部分或要成为新型态的抗生素不仅要有强大的抗菌活性还需要有高度的选择性，由本实验的结果发现，当抗菌胜肽的正电荷及极性角度增加时，胜肽之抗菌活性会随之增加，当抗菌胜肽的电荷为＋4而极性角度为 140°时，胜肽有最强之抗菌能力及膜渗透活性；而随著胜肽疏水性以及疏水性矩的增加，会增加溶血活性，结果反而降低了抗菌胜肽的选择性。

The shapes and forms of tetrahedral tetrads grains may be described with a new method of polar coordinate that is more exact and more direct than with traditional measurement method of polar axis and equatorial axis.

用极坐标法描述四合体花粉的新方法可以表现其饱满度，比较传统上用极轴、赤道轴的长短表现花粉平面大小的方法，更加准确而直观。

First, normalized polar coordinate translation is carried out in the shape region with an origin at the middle of the region and a polar axis of the longest region orientation axis. Then, interval operations are defined between inner point intervals of the region at the same orientation.

该算法首先以形状区域的中心点为极点，区域的最长轴方向为极轴，对形状区域进行归一化的极坐标变换；然后定义了同一角度对应的区域内点区间之间的运算；最后定义了两个区域归一化极坐标变换结果在区间运算下的相似度函数，用以表征两个区域之间的匹配度。

Since polar organic crystals have noncentric structures, the existence of polar axis in the crystals has a significant effect on the molecular arrangement and on the crystal growth.

极性有机晶体在不同的溶剂中具有明显不同的生长习性，主要有两个方面的原因：一是极性有机晶体属非中心对称性晶类，晶体具有极轴，极轴的存在对分子堆积和晶体生长具有重要影响；另一是极性有机晶体的界面结构不同，溶剂与晶体界面的相互作用不同，使得晶体同一面族的生长速率不同，从而导致了晶体习性的改变。

It was determined that it would cause massive earthquakes, volcanoes, tidal waves, the melting or shifting of the polar ice caps, sudden fluctuations in temperature and climatic conditions, and probably a shift in the polar axis of Earth.

据测定，它会造成大规模地震、火山、海啸、熔化或推诿极地冰盖，气温突然波动和气候条件，可能划在地球极地轴心。

Unfasten the Decl. clamp and turn the optical tube until it is nearly at right angles to the polar axis. If you do not do this, the polar axis scope will be shaded with the Decl. axis and can not be used.

松开赤纬制动钮并转动望远镜镜筒直到它与极轴镜的角度接近直角，如果你不如此做，极轴望远镜将被赤纬轴遮挡而无法使用。

Polar bear, polar bear, what can you do?

北极熊啊北极熊，你会做些什么呀？

About 30～35 min after insemination the first polar body was ejected and the second polar body was ejected about 10 min later.
