褶皱解析的数学方法及c程序

MATHEMATICAL METHOD AND c PROGRAM FOR FOLD ANALYSIS

褶皱解析的主要或关键内容是用极射赤平投影求解褶皱的枢纽及轴面 ,通过对褶皱两翼大量产状数据的处理以获得较为精确的枢纽及轴面的值。用计算机语言编制程序实现这一过程 ,速度快、精度好、效率高 ,克服了传统手工操作的诸多缺点 ,文章详细阐述这一过程的原理及数学方法 ,并使用c语言进行程序设计。

The key or main contents of fold analysis are to solve its hinge and axial plane by stereographic projection, to gain more accurate values of hinge and axial plane by analyses many of attitude's data at fold's limbs. It is faster speed, more precise and efficient that programming with computer language to realize this process, it overcomes a lot of defects by hands. this paper clarify its principle and mathematical method detailedly, and give its c language program with full Chinese interface to indicate and easy to use. Key Words: fold; axial plane; hinge; stereographic projection紸bstract:Broodstock Epinephelus coioides was cultured with enriched feeds and natural spawning was carried out in indoor ponds. The three groups of 91 broodstocks after enrichment culture spawned 120 times in 77 days, and produced 262 8 million eggs, of which 70 2% were floating eggs. The fertilized rate of the floating eggs was 92 5% Spawning of the broodstocks of Epinephelus coioides showed its close relationship with water temperature, and the optimum water temperature for spawning ranged from 24℃ to 27℃.
