查询词典 concave mirror

A concave parabolic mirror with the diameter of 140 mm and the F number is 2 is tested by using this method.

利用该方法对一直径为140 mm，F数为2的凹形抛物面镜进行了测试实验。

The best match between the rear shapes and support patterns is suggested. The rear 3-point support pattern of concave primary mirror is computed for its deformation under various working condition and the best support position is found out.

找到了主镜的背部形状与其支撑方式间的最佳配合关系；对双凹形主镜的背部三点支撑方式进行分析计算，找到了它的最优支撑位置。

Two different Fabry-Perot cavities have been adopted: plane mirror cavity and confocal concave spherical mirror cavity.

采用了两种不同的Fabry-Perot腔体结构：平面腔镜结构和对称共焦球面腔镜结构；首先进行了理论分析，得出两种结构中折射率变化与干涉条纹变化的关系，然后分别对两种腔体结构下的测量系统进行实验研究，都可以探测到10-5量级的折射率变化量，结果基本令人满意。

Hockney surmises, however, that this convex mirror could be turned around and used as a concave projection mirror: If you were to reverse the silvering , and then turn it round, this would be all the optical equipment you would need for the meticulous and natural-looking detail in the picture.

但霍克尼的猜测是，把这个凸面镜前后反转过来，便能当成可投射的凹面镜来用：「如果你把银涂在凸面镜的反面，并将它反转过来，就变成能做出精细自然画面的道具了。

Convex and concave surface is configured on the LCD panel as the treatment to reduce the reflection of mirror.

在液晶面板表面设置凹凸，以降低镜面反射之处理。

Under the same conditions, the mode distortions induced by the tilted mirror are smaller for the plano-concave resonator with the Gaussian-reflectivity, and the relations of the field distributions with Gaussian-reflectivity to the tilt angles are different from those with even-reflectivity.

同等条件下，高斯反射率平凹腔腔镜倾斜对谐振腔引起的模畸变小于均匀反射率平凹腔，且基模光场及本征值随镜倾斜的变化关系稍不同于均匀反射率平凹腔。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
