The visible spectrum of Mo in Ti-based alloy was analyzed by a digital spectroscope. Mo 553.31nm and Ti 551.44nm were selected as spectral lines for analysis and comparison. Samples of Ti-based alloys with different Mo contents were analyzed quantitatively. The data indicated that the ratio of intensities between analytical spectrum and comparison spectrum has a positive relationship with the content of Mo.

通过对元代、明洪武及明宜德年间的景德镇青花瓷样品彩上斑点的显微结构和组成分析，研究了斑点的形成机理和组成，表明青花瓷彩上斑点是由青花钴料中的锰、铁、钴，经高温过程后，在釉熔体中的偏析所形成的，其物像组成，除主要取决于青花钴料中的锰、铁含量外，样品的胎、釉组成及烧成机制等也影响着铁的价态。

In the paper, the electrode system of the original TL/TSC measurement instrument is improved, which greatly facilitates sample exchange and increased liquid nitrogen's running and cooling speed. Through long time and repeated practice we finally find an effective method to prepare films. We've synthesized a new kind of organic photo-refraction material nitryl azobenzene grafting PVK and characterized it with IR spectra. We've also synthesized 5OCB and found the optimal mass ratio of PVK/5OCB/C60-49.8:50:0.2, and given the two-beam coupling testing result.

Companies also differ markedly in their beliefs about the efficacy of such promotions: whereas over 50% of sales at Estee' Lauder are associated with free gift with purchase promotions, chanel does not offer any, and Aramis is moving from gifts to sampling, with over a quarter of its marketing budget devoted to free samples of newly introduced products.

公司对於这种促销效力的看法也明显不同：与&雅诗兰黛&有超过50%的销售是和购买促销活动的免费赠品有关而相反的是，&香奈儿&并不提供任何东西，而&雅男士&则把赠品换成样品，将它超过四分之一的行销预算投注在新上市产品的免费样品上。

A number of sourceless cores, UC HII regions and their physical parameters were obtained. Initial conditions of masive star formation were inspected. This provided samples for further larger observations.

The studies was proceeded on the the supercritical CO2 extraction technique of rotenone from Tephrosia vogelii. The extraction influences of technology conditions were systematically groped, The research results were listed as follows:1 The analysis method applied in this paper has been proved to be suitable to technology research of the studies on the SC-CO: extraction technique of rotenone from Tephrosia vogelii. 3 indexes, extraction ratio of rotenone. extraction ratio of total compounds and rotenone content percent in total compounds weight, were carried out with HPLC quantitatively determination combined with the sample weight loss after extraction. With these 3 indexes. The extraction influences of technology conditions were evaluated by synthesis. Then the best technology conditions were ascertained for different extraction aims.2 The pretreatment of rough material should be needed before extraction. Comminuting the material to 0.28mm size is most fit to SC-CO: extraction.3 Firstly static extracting 20 min then turn to dynamic doing is the better extraction mode than other ones.4 The orthogonal experiment was conduct with 3 factors and 5 levers.

本论文通过对非洲山毛豆SC-CO_2萃取中影响萃取效果的工艺条件的研究，初步得出如下结果：(1)本论文中所采用的萃取效果评价方法适宜于非洲山毛豆中鱼藤酮的超临界流体萃取技术研究，该方法具体为：HPLC定量分析非洲山毛豆SC-CO_2萃取物中的鱼藤酮含量，再结合萃取前后处理样品的重量损失，得出鱼藤酮萃取率、萃取所得粗物质萃取率和粗物质中鱼藤酮含量三个参数，以此三个指标综合评价萃取条件对萃取效果的影响；(2)通过对原料粒度对萃取效果影响的研究，结果表明SC-CO_2萃取非洲山毛豆复叶中的鱼藤酮，原料粉碎成30目粒度叶粉时萃取效果较好；(3)通过对萃取方式与萃取效果之间关系的研究，结果表明SC-CO_2萃取非洲山毛豆中鱼藤酮应采用先静态后动态的萃取方式，静态萃取时间为20min；(4)通过温度、压力和CO_2流量三因素五水平的正交试验，结果表明温度是最主要的影响因素，压力因素对鱼藤酮萃取率的影响程度高于CO_2流量，而对于粗物质萃取率和粗物质中鱼藤酮含量CO_2流量因素高于压力。

Laser confocal scanning microscopy is a new technology combining modern optics and electronics. The unique feature of point light source and point detecting eliminates out-of-focus blur and spots. Therefore, the axial and lateral resolution of the system is superior and 3-D imaging can be realized by scanning point by point of the object profile. Because of its advantages, confocal measurement technology is widely applied in many fields, such as medical treatment, biology, configuration of substances and micro-electronics.
