The reflectivity of an object depends very much upon the nature and smoothness of its surface 每一件物件的反射能力,由物件反射面的物质和平滑程度所决定。
The surface of glass is very smooth , and a coating of aluminium renders it an ideal material for making mirrors 玻璃的平滑度高,加上铝质的反射面,成为最佳的造镜材料。
By analyzing the scanning galvanometer the effect of offset between reflector surface and its rotate axis is given quantitatively 通过对扫描振镜的分析,定量给出了反射镜反射面与振镜转轴偏心对扫描光线的影响。
Acoustics - determination of sound power levels of noise sources using sound pressure - survey method using an enveloping measurement surface over a reflecting plane 声学声压法测定噪声源声功率级反射面上方采用包络测量表面的简易法
So first we hear the direct sound ; then , a short time later , a number of discrete reflections return from the various surfaces in the room 所以首先我们先听到直达声;然后,一个短时间的延迟后,一连串不连续的反射声在房间的不同反射面之间反射回来。
The simulation and test have been carried out for a metallic photonic bandgap ( mpbg ) reflector antenna , with an explicit method as well as a genetic algorithm 采用一种快速的计算方法,并结合遗传优化算法,进行了金属光子晶体( mpbg )反射面天线的模拟与实验。
However , these reflections don ' t just stop when they reach the listener - - they continue until they reach other surfaces , where they instigate more reflections 当然,这些反射声不是到达听众就立刻停止传播的,他们会继续传播,直到碰到另外一个反射面,然后产生更多的反射声。
Poor : several conditions exist that could ( directly or indirectly ) have an adverse effect upon product container appearance or quality . no reflective surfaces present over palletizers 差:有一些可能(直接或间接)对产品容器外观或质量有不利影响的条件存在。在卸垛机上方没有反射面。
Each palletizer is equipped with an approved overhead reflective surface ( stainless foil ) that is clean and so positioned as to permit operator to view inside surface of every container in bed 每个卸垛机上方配备认可的清洁的反射面(不锈钢箔)这样可以让操作者查看底座上的每个容器内表面。
In the absence of sideway spin , the ball when hitting a hard surface should follow a path similar to that of light ray , i . e . , the angle of reflection equals the angle of incidence 利用坚硬的反射面,并在没有侧旋的影响下,球的反射路线与光的反射路线应该是一致的,即球的入射角与反射角相同。
