Sail area is usually planned by boat designers based on the boat's size, displacement (weight), and hull shape and configuration - not the number of masts or sails.
帆面积通常是由帆船设计者根据帆船的尺寸，重量，船底形状和配置来确定的，而非根据桅杆或船帆的数量。

The plane displacement of hyperelasticity was discussed. Aimed at a complex strain energy density function, a group of hyperelasticity governing equations defined on initial configuration were solved.
The result shows that optical fiber displacement sensor's sensitivity problem to temperature can be well eliminated by using such configuration as well as choosing the proper data processing.
