Leastsquare method and Lagrange's interpolation formula see their applicationsfor fitting fore-and-aft lines-whose aim is to calculate the intersection point ofequivalent inclined waterline-and differences. In order to replace theinconvenient alternate conduct of drawing and calculating, improvement hasbeen introduced into the paper which means all work can be done bycomputer. Capacity calculation cannot be done without boundary layer build-up. Fit every area curve and area moment curve is necessary because ofinterpolation.

The results of lattice beam internal force calculated method based on double parameter groundsill model are more approach the experiment measured values because of consideration of the pass of shearing force in soil, and its calculated workloads are similar with the method of winkler elastic foundation. Besides, the thesis also discusses the moment of torque affected results on node stress situation and the correction of stress value at the bottom of cross node of lattice beam. Due to the repeat calculation of node area during internal force calculation, the stress value of the bottom of beam is lower, this may lead the calculated value unsafe, but the corrected stress value will more approach to practical situation.
对格构梁的内力计算提出基于双参数地基模型的格构梁内力计算方法,其计算结果表明,双参数地基模型上的格构梁内力由于考虑土中剪力的传递更加接近于试验实测值,其计算工作量与winkler弹性地基梁法相当,此外,文中还探讨了扭矩作用对格构梁节点受力情况的影响结果以及格构梁交叉节点底部的应力值的修正,由于内力计算过程中节点处的面积被重复计算,使得梁底应力偏小,可能导致计算结果的偏于不安全,修正后的应力值更接近于实际情况。

It is shown that maximum temperature value of the field's will rise while the Mach number increases. After the Mach number exceeds one, a clear bowshock is obtained in the simulation result, and the Mach angle decreases along with the Mach number. Those are consistent with theoretical results. While the Mach number is 3.5, even the radome inside is adiabatic, the maximum temperature is below 1000K. So the CVD diamond thick film radome can meet practical requirement of flight at 3.5 Mach number.
研究发现,随着马赫数的增加,温度场中最大温度值也随之增大;在马赫数大于1时,会产生明显的弓形激波,且激波的锥角随马赫数增加而减小,这与理论结果相一致;当马赫数为3.5时,即使在头罩内壁绝热条件下,温度场中最高温度值也在1000K以下,表明CVD金刚石厚膜可以满足Ma=3.5的实际飞行要求。
