镜片

Well I could put a little glue on the screw to stop it from loosening but that would make it difficult to take the lenses out if you want to change them in the future

我可以在镙丝钉上放少许胶水以防它再松开。但如果你以后想把镜片拿出来更换便会困难一点了）。

Moreover, one novel photochromic compound: 3,3-bis(4-methoxybenzyl)-3H-naphtho[2,1-b]pyran has been synthesized, which may be used in optical lenses to protect human eyes from being damaged by ultraviolet lights.

该化合物具有较好的光致变色性质，其开环式的颜色与吡啶并苯恶嗪的颜色互补，这两种化合物相结合构成第二代Transitions镜片的基础。

Although it is sometimes claimed to be a successor of the famous Zeiss Jena Notarem, the similarities are few and I suspect that these binoculars were actually designed from scratch. The 42mm objective is a quadruplet, i.e. made of no less than four lens elements.

虽然有时声称是著名的Zeiss Jena Notarem的继承者，但相似点很少，我猜测这些镜子实际上是从零做起的。42mm的物镜是4组的，就是说，由不少于4片镜片构成。

One kind of red soft contact lenses that could correct most red-green blindness effectively were chosen after various tests.

通过反复探索，研制出了一种对大多数红绿色盲患者都能满意矫正的色盲镜片。

Methods Some volunteers with red-green blindness were selected to wear the differently tinted red soft contact lenses.

通过志愿者试戴研制能矫正红绿色盲的色盲镜片。

But sufferers looking for a "crutch" can easily find Internet offers of special lenses with color filters supposedly able to correct red-green color blindness.

这些镜片据说能够调节红绿色盲。

This is very important in modern lens, the reflective glass surface decreased, so that there is more than a dozen pieces of the zoom lens on a reflective glass surface will be much less, so that the light through the lens will not be significantly reduced.

这在现代镜头上非常重要，玻璃表面的反光下降，这样在有十几片镜片的变焦镜头上的玻璃表面的反光就会少很多，这样通过镜头的光就不会明显减少。

In this paper,the reflectivity of cavity mirror s as well as reflective mirror have been measured with this technique.

该方法适用于不同环境下的镜片反射率的精确测定。

In chapter one some simple remarks are made of the development of the technique for high reflectivity measurement of optical coatings.

第一章简单回顾了高反射率光学镜片测量的发展历程。

Very fast changes, from the angle of the light or refringence, or refringence to go to focusing lens group

极快的速度改变角度的，通过不同的角度，将光或者折射走，或者折射到聚焦镜片组

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
