查询词典 central angle

The reflection spectra of Al0.5Ga0.5As-AlAs distributed Bragg reflector at different incident angle are calculated by transfer matrix method. The reflection spectra curve of p-polarized and s-polarized plane waves vary with a 'V' shape with the rise of the incident angle and the lowest reflectivity is at 49.8°.

Accordingly, if much of the cane in the field is included at an angle of away from the travel of the harvester, the front end 20 of the harvester may be controlled so that the semi-erect and lodged cane stalks are also positioned at the same approximately angle in a direction away from the travel of the harvester during the topping operation.

因此，如果甘蔗地里的所有甘蔗杆都与收割机前进的方向倾斜成70度的角的话，那么，就要对收割机的前端20进行调整，使半倒伏和倒伏的甘蔗杆在进行切顶时同样也与收割机前进的方向倾斜成70度的角。

However, because of the limitation by circular orbit, we can't obtain all the data in Radon Space which means that the result becomes better with the cone angle decreases. So it is important to study the relationship between the cone angle and the reconstruct quality further.

但是由于圆轨道几何结构的限制，使其不能够得到完备的锥束重建数据，只有在锥角较小的情况下才能得到，因此深入研究Radon空间的数据缺失与锥角的关系以改进算法。
