Second, glass is reflective, but again we must examine how this reflectivity works.

第二，玻璃的反射，这样我们又得研究它的反射率是如何的，它的表面是镜面反射的，因此没有太多的漫反射在其上。

The type of shock reflection over 50o wedge model is of regular reflection. The angle between the incident and reflection shock is also being increased as the model surface roughness increased. The flow visualization results indicate that the speed of reflection shock becomes slower.

在50度的模型实验条件下则会产生正规反射，当增加表面粗糙度后会使得射震波与反射震波之夹角增大，由上述两者结果可以发现，其结果可归因於反射震波之移动速度减缓所致，因此增加表面粗糙度必然会使震波反射有减弱的情况发生。

The off-axis reflection system composed of four aspheric mirrors was designed, but the system structure was not so simple and the performance can also be improved, besides, manufacture and test for large aspheric mirrors are difficult; and then the spherical Fresnel mirror which is easier to be manufactured and tested was used to replace the aspheric mirror, the spherical Fresnel mirror has low cost of replication, but this design also can\'t be used in projection lens because it was only feasible in narrow wavebands; Furthermore, the design making use of catadioptric projection lens was accomplished, this design is greatly applied in rear projector because it has merits of both refraction and reflection. But it had difficulties in color aberration correction and had complex structure.

设计了四片非球面组成的离轴式反射系统，然而，仅采用非球面设计系统结构不够精简，性能也有待进一步提高，且非球面面形较大时加工和检测都存在一定的困难；继而提出了用球面Fresnel反射镜代替非球面的设计方法，虽然Fresnel反射镜加工和检测更为简单，且复制成本低，但对波长具有选择性；进而，应用折反系统结合的方式设计了离轴式投影镜头，该方法因兼具折射和反射的优点，在大屏幕超薄背投系统的设计中广为应用，缺点是会产生难以校正的色差，且结构复杂。

Referring to the optical rounded reflector of spherical surface used in a space remote sensor, a kind of flexible structure was designed for regulating thermal deformation.

According to the simulated results, it was found that the incident light was not fully absorbed in the solar cell due to a thinner base layer. The un-absorbed incident light could be further reflected by a AuGe/Au mirror layer and absorbed again by the base layer. Thus the disadvantage of the GaAs thin-film cell with a thinner base layer could be solved by the additional reflection from the AuGe/Au mirror with a high reflectivity within 800~1000 nm wavelength. Moreover, the external quantum efficiency in the long wavelength region and short current density were also increased.

从模拟结果中得知，薄膜型结构之太阳电池可以经由AuGe/Au之金属反射层，再次将未被基极层完全吸收之入射光反射回太阳电池，使得薄膜型结构在长波段的外部量子效率获得提升，这结果显示薄膜型结构太阳电池可利用AuGe/Au之金属反射层在长波段的高反射率，改善使用较薄基极层时，无法将入射光完全吸收的缺点。
