光度

In the beginning of thesis, we present the works on the search of variable stars and light curve analysis.

在论文的前半段，我的工作重心放在建立快速搜寻变星的方法还有变星光度曲线的分析上。

The spectrum of SN1987A contains more detailed information than its bolometric light curve.

The suitable growth environment for Zantedeschia aethiopica in Guiyang region was to sow it in April and it was appropriate to adopt the combination treatments of the weak light with 50% shading combined with 3 kinds of soil under the vested natural temperature.

结论］彩色马蹄莲在贵阳地区生长的适宜环境是在4月份开始下种，在既定的自然温度条件下，以遮光度为50%的弱光与3种类型土壤的组合处理为宜。

In this work, GC-MS, ICP-OES, UV-Visible Spectrophotometry were employed to determine the trace concentrations of the above six hazardous substances, and a standard method system for screening primarily, extraction, qualitative and quantitative analyses of the six substances was established and their factors were analyzed. By evaluating the relative standard deviation, recovery, repeatability, limit of detection, linear relation etc., the optimum parameters were given and thus the precision of analysis was equal to or higher than the IEC 62321 standard, meeting the requirement of RoHS.

针对中国电子电气业在遵守RoHS符合性实践中存在的诸多问题，本文采用GC-MS，ICP-OES，UV-Visible分光光度法等，对我国南方和香港地区各类电子电气产品中六种有害物质进行痕量分析，建立了一套标准的六种有害物质初步筛选、萃取、定性、定量分析方法，并对此方法体系的影响因素进行分析，对其相对标准偏差、回复率、再现率、检出限、线性关系等进行评估，得出了优化测试参数，在此条件下其检测的精密度达到或高于国际IEC 62321标准，满足RoHS测试要求。

The linear relationship between the concentration and absorbance of was significant.

两者的浓度和吸光度之间都存在极显著的线性关系。

The results showed that the stability was good and the absorbance fluctuates lisle at pH=3~4, the temperature was at 15~28℃, the chromogenic reagent was 2mL and the time of coloration was 20~40min.

结果表明：pH值在3~4之间，温度在15~25℃之间，显色剂用量为2mL，显色时间在20~40min，显色稳定，样品吸光度无明显变化，实验能达到较理想的效果。

A star of the second magnitude, at the end of the ''.'handle'.'' of the Little ''.'Dipper'.

And this key manner is also use for analyzing the status of LED road lighting luminaire from 2007 till now.

揭示了评价LED 路灯光度特性优劣的核心方法，并用此方法对2007 年至今的LED 道路照明灯具的状况进行

Highlights: Visually the brightest, or photometrically the most luminant areas of a subject.

高光部分：最高的，或光度测定值最大的发光体物体的某一部分。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
