In order to understand the light and color properties of the high-end displays,some characteristics,including light uniformity on different areas on screen, lightness and chromatics,CIE_xy chromaticity gamut,and their change with viewing directions,were measured for one CRT and one LCD monitors.

为了明晰高端应用的CRT和LCD显示器的色光特性，测试分析了两类各一个显示屏幕在暗室和明室环境中色光的位置均匀性、光亮度和色度、CIE_xy色品域，及其随水平观测角度的变化等特性。

Can undertake nutrition of light energy inorganic is divided inside the cell of general alga contain and the light with advanced same plant adds up to green outside pigment, some kinds group still have in all special pigment and also do not show green more, so their plastid calls chromatophore especially or hold lubricious put oneself in another's position.

能进行光能无机营养一般藻类的细胞内除含有和绿色高等植物相同的光合色素外，有些类群还具有共非凡的色素而且也多不呈绿色，所以它们的质体特称为色素体或载色体。藻类的营养方式也是多种多样的。例如有些低等的单细胞藻类，在一定的条件下也能进行有机光能营养。

Results showed that the change of photosynthesis of the first whorl of leaves was similar generally between the stock and the cion, changing from leaf discolor, grey green, stable to senescent stages, and that the max net photosynthetic rate P(superscript max, photosynthetic saturated light intensity and chlorophyll content of the leaves changed continuously with the phenophases, which rose rapidly and then dropped slowly after the peak, whereas the change of their light compensation point was just the opposite.

结果表明，橡胶树籽苗芽接苗砧木和接穗第1蓬叶的光合特性变化规律基本相似，从变色期、淡绿期、稳定期，到衰老期，其叶片的表观量子效率、最大净光合速率P(下标 max、光饱和点和叶绿素含量等均随着物候期变化而不断变化，变化趋势为先迅速升高，达到最高值后缓慢下降；光补偿点的变化趋势则相反。

Much of the gas in the disk of the Circinus spiral is concentrated in two specific rings -- a larger one of diameter 1,300 light-years, which has already been observed by ground-based telescopes, and a previously unseen ring of diameter 260 light-years.

在圆规座的漩涡星系中的大部分气体都与两个具体的"环"有密切的联系。那个较大的，直径大约有1，300光年，它已经被地基望远镜观测到了。而先前，我们没有观测到的那个小"环"，直径大约有260光年。

Now an international team of astronomers has finally observed the acceleration of protons within a shock wave. Using the Very Large Telescope in Paranal, Chile, and NASA's Chandra spacecraft, they measured the visible light and x-ray emissions of the remnant of a supernova about 8200 light-years away in the direction of the constellation Circinus.

现在，一个由天文学家组成的跨国研究小组终于观察到激波内部质子的加速情况，他们利用智利帕拉纳尔的甚大望远镜和美国国家航空航天管理局的钱德拉太空船，测量到了圆规座方向大约8，200光年处一颗超新星残骸发出的可见光和 X 射线。
