亮度

Once the type of star is known, its true brightness, called intrinsic luminosity, can be determined.

一旦恒星的类型已知，她的真实亮度，也叫本质亮度就可以确定了。

Lawrence martyr , 10 august : the monthly recurrence known as the new moon with the old moon in her arms : the posited influence of celestial on human bodies : the appearance of a star 1st magnitude of exceeding brilliancy dominating by night and day a new luminous sun generated by the collision and amalgamation in incandescence of two nonluminous exsuns about the period of the birth of william shakespeare over delta in the recumbent neversetting constellation of cassiopeia and of a star 2nd magnitude of similar origin but lesser brilliancy which had appeared in and disappeared from the constellation of the corona septentrionalis about the period of the birth of leopold bloom and of other stars of presumably similar origin which had effectively or presumably appeared in and disappeared from the constellation of andromeda about the period of the birth of stephen dedalus , and in and from the constellation of auriga some years after the birth and death of rudolph bloom , junior , and in and from other constellations some years before or after the birth or death of other persons : the attendant phenomena of eclipses , solar and lunar , from immersion to emersion , abatement of wind , transit of shadow , taciturnity of winged creatures , emergence of nocturnal or crepuscular animals , persistence of infernal light , obscurity of terrestrial waters , pallor of human beings

As the edge pixel value varies from non-edge pels value largely, which resulted that it can't satisfy the condition of building GM(1,1,C) and the error of GM(1,1,C) whiterization value is large.

依据边缘像素点其亮度与非边缘像素点亮度相差大而不满足GM(1，1，C)建模条件，从而导致边缘像素点白化值误差大的特点，实现边缘检测。

The Bridgelux Arrays used in the Helieon Sustainable Light Module deliver between 500 and 1,500 operational lumens (performance comparable to or greater than 40 to 75 Watt incandescent bulbs) in a compact high flux density light source. These integrated solutions deliver high quality light without pixilation, closely replicating the beam quality of traditional light sources.

Helieon长寿光源模组所应用到的Bridgelux距阵介于500到1500流明（亮度相当于或超过40W~70W的节能灯泡），光源设计紧凑，亮度高，而且光效好无闪烁，非常接近于传统光源的光效。

We also tested many of the low priced strobes on the market and found the Fantasea Remora Package to offer the brightest light and best quality for entry level options.

我们还测试了很多低价的闪光灯，最后发现，Fantsea Remora套装能提供最高亮度的闪光亮度，而且是入门级产品中，质量最好的。

Streetlight project measure and proved that the brightness I 40W LED light source is equivalent to 250W sodium lamp

For experimental setup to calibrate spectral radiance by applying a diffuse plane, the measured spectral radiance can be obtained through integral of spectral radiation flux entering the spectrometer.

在利用漫反射板标定光谱辐亮度的实验装置中，标准灯完全可以近似为点光源。通过对进入光谱仪的辐射通量的数值积分，可以对应求出仪器的实测光谱辐亮度的计算公式。

Brightness of aware sort is the classification norm of distance classification. Distance classification compares brightness between aware sort and unknown pixels. Angle of spectral line is the classification norm of degree classification. Degree classification compares angle of spectral line between aware sort and unknown pixels.

距离分类器是以已知地物类别的亮度值作为分类基准，通过比较未知类别像元与已知类别像元亮度值间的距离进行分类；角度分类器是以光谱谱线角为分类基准，通过比较n维波段空间中未知类别像元与已知类别像元光谱角度进行分类。

We will see more and more activist government policies that distinguish economic activities according to the nationality of the actors.

我们将看到越来越多激进的政府政策，这些政策根据企业的国籍来区分经济活动。

If we can prove the independence of an axiomatic system, then we can guarantee the conciseness of this system, ie.

如果能够证明某个一阶谓词系统的独立性，那么就能够保证该系统的建立是精炼的，即没有任何一条公理或推理规则是多余的。
