Based on several exiting mathematical models , an off - line temperature simulation software was developed to improve the control effect on strip head temperature in finishing rolling process and draw up a more reasonable inter - stand spray water cooling scheme 摘要为了提高热轧带钢头部终轧温度命中率，以及确定合理的机架间喷水冷却制度，结合带钢热轧过程温度数学模型，开发了精轧区温度模拟计算软件。
Solution of nonlinear wave loads in regular oblique seas . based on strip method , thinking about nonlinear factors such as no straight shipboard on waterline , the instantaneous variation of wet surface shape and slamming effect of ship bottom , the numerical methods of nonlinear fluid force in large amplitude oblique regular seas are discussed 关于斜浪规则波中非线性波浪载荷的计算:本文基于切片理论，考虑到船体非直舷、水下剖面形状的瞬时变化以及砰击等非线性因素，讨论了大波幅斜浪规则波中非线性流体力的时域计算方法。
