照度

Three LEDs biology light sources with different intensity for cell or tissue culture have been developed in the third part of this thesis. A concave lens to expand the beams of light, to focus the rays of light and an array of LEDs being set in the sphere connected with Fresnel lenses are three newly-designed in our systems.

实际测试数据表明：低强度光源输出的辐射照度范围为0.0021—0.9961(W／m~2)，在直径20mm的照射面积内所测辐射照度的标准偏差为0.02W／m~2(n=40，Mean：0.71 W／m~2)；中等强度光源输出的辐射照度范围为0.3579—11.2286(W／m~2)，在直径30mm照射面积内所测辐射照度的标准偏差为0.02W／m~2n=60，Mean：6.37 W／m~2；较高强度光源输出的辐射照度范围为17—110(W／m~2，在直径40mm照射面积内所测辐射照度的标准偏差为0.02W／m~2(n=80，Mean：71.54 W／m~2)。

The best of comprehensive efficiency between natural lighting and heat insulation is Low-E glass, the best performance of natural lighting is clear glass, but performance of heat insulation is bad, the best performance of heat insulation is green semi-reflective glass, average daylight factor is about 1% over, 0.7% of residential standards, but its illuminance is not suitable about 200 Lux.

平均昼光率与室内玻璃表面温度标准差之比值的综合效能评估中，Low-E玻璃为采光与隔热综合效能最优异之材质，而清玻璃为采光效能最优异之玻璃材质，但清玻璃隔热效能不佳，绿色半反射玻璃的隔热效果最好，而采光方面的昼光率平均为1%，采光虽然还符合住宅的昼光率标准0.7%，但照度普遍不佳，平均室内照度约200 照度。

At last the luminance and the guide number of the flash lamp is measured respectively by illuminometer and digital camera.

最后采用照度计和数码相机对实现的LED电子警察闪光灯进行发光照度和闪光指数的测量。

This paper use new method on the forecastle deck's lumination calculation ,then dedude currency formula for every light which fixed with some angle .

在对艏楼甲板进行照度计算时还引入了新的方法，使我们对一些有一定倾角安装的灯具的照度计算有了通用公式。

The ratio of the minimum to the average illuminance.

照度最小值与照度平均之值比。

The ratio of the minimum to the maximum illuminance.

照度最小值与照度最大值之比。

Illuminometer:Ultra - Violet Radiation Illuminometer , Light Illuminometer

验光机：验光机；47。照度计：紫外辐射照度计、光照度计

The supervision of the luminous is realized for measurement where image intensifier is placed.

且设计实现了对像增强器处检测照度的监控，保证检测照度稳定。

This paper introduces three traditional ways which are use coefficient lumimethod, power to square ratio method, inverse square law to do the lamination calculation for the representative room and deck, and do some contrast for the room which can use two way to do the calculation .

本文采用传统的三种照度计算方法：利用系数法、比功率法、逐点法对相应典型舱室和甲板进行了照度计算，对一些可以用两种方法计算的舱室的计算结果作比较并分析了原因。

The artifical illumination circumstance of the library of Three Gorges University was measured by JD-3 luminometer; and its numerical values of artificial illumination were gained scientifically.

采用JD-3型照度计，对三峡大学图书馆阅览区工作面上的人工照明光环境进行测量，从数量上比较科学地得出了该馆的照度数值。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
