These cracks occurred at either the beam flange or in the column flange depending on the reentrant corner weld angle . 这些裂纹视凹形焊角的不同，或者出现在横梁翼缘上，或者出现在立柱翼缘上。
As design studies progressed it was found that several airfoil shapes could be used to satisfy the new performance criteria . 当进行设计的研究工作后，发现有几种翼型可以用来满足新的性能指标。
The tail lift curve slope as determined from the panel model may require adjustment in order to apply the test results . 为了应用试验结果，根据翼段模型试验确定的平尾升力曲线斜率可能要作些修正。
It is often necessary to determine the satisfactory release characteristics of tip tanks, underwing stores, bombs, or other devices . 经常有必要测定翼尖油箱，翼下外挂物，炸弹或其它装置的投放特性。
