According to the results of this study, the ultimate strength of pin-bone interface increased as the moment arm decreased and torque increased. When the pin-bone angle approached 90°, the ultimate strength was the largest and as the angle decreased, the ultimate strength decreased. There was no significant difference between rigidity and torque, but rigidity decreased as the skull-bone angle decreased.
结果发现钉骨界面的极限强度在头圈距离颅骨的力臂短时较高,且随著所用扭力的增加而增加,当头钉与头骨表面的夹角成垂直时最强,随著夹角越趋锐角而渐减,钉骨界面的刚性与扭力并无明显关系但与夹角有关,夹角垂直时刚性最高,而后随著夹角渐趋锐角而递减。

To further study this problem, the optical axis is rotated by an arbitrary angle. A striking phenomenon is discovered that the Brewster angle is always equal to the rotation angle. This is because the waves in the direction perpendicular to the optical axis become evanescent since the permittivity is positive while the permeability is negative in this direction.
然后进一步的研究了主轴不垂直于界面的情况,发现主轴转动的角度恰好等于此时的Brewster角,这是因为此时垂直于主轴的方向上介电常数为正磁导率为负,只有倏逝波而没有可传播的波存在,因此反射系数为0。

Chirp scaling algorithm is considered more efficient and widely applicable when the bistatic SAR system is in side-look or small squint angle mode,but in large squint angle case,the errors caused by Taylor expansion are so large that the algorithm could lose its precision.In such a case,an equivalent mono-static SAR range mode which has fewer errors than Taylor expansion with large squint angle is proposed to substitute the range history of bistatic SAR.Then bistatic SAR images with large squint angles are gotten by common Nonlinear CS algorithm.The effectivity of the method is verified by Matlab simulation.
