Quaere that is there any means which can be used to measure the barycentre of sword easily? 还有请问一下重心不对会对用剑者有跗面影响？？？？

At last, the azimuth angle and the elevation angle are derived from the aim area barycentre. 最后通过鱼眼图像中太阳斑区中心点计算出太阳与视点之间的高度角与方位角。

High hydrophobicity and an imbalance between the center of mass and the barycentre of its hydrophobic regions decreased the activity. 高疏水性以及质量中心与疏水区中心的高不平衡性对活性是不利因素.

Before installation, first find out the barycentre of the load. The mounts must be symmetrically installed. Choose the suitable type according to the weight of the load. 垫铁安装前要先找出负荷的中心，垫铁必须做对称配置，按照承载值选择适当的型号。

This paper develops a set of barycentre of plane automated control system based on industrial personal computer and programmable logic controller aiming at the defect of avionics in our country. 摘要针对目前我国机载航空电子设备特别是重心控制设备的落后现状，设计一套基于工业控制计算机和可编程逻辑控制器的飞机重心自动控制系统。
