Statistics analysis and some diagnostic ratios were used for source identification and the contribution rates of main sources were also calculated. Pyrogenic PAHs and petrogenic PAHs accounted for 70.97% and 11.38% and 64.93% and 14.11% respectively. PAHs in the road dusts from Shanghai urban area were mostly generated by incomplete combustion.

The first type is E s 1 and E f 3 member oil, which is derived from E f 2 member source rock of deep sag. The second type is E f 1 member oil which is derived from E f 1 member source rock of deep sag. Integrated with the analysis of pyrrolic nitrogen compounds and its parameters, Beihanzhuang E f 3,/E f 1 and E s 1 member oil migrated from deep sag to Beihanzhuang structure belt apparently.

研究结果表明，北汉庄油田的原油可以划分为2类：第一类原油分布于垛一段与阜三段，主要来源于深凹带阜二段烃源岩；第二类原油分布在阜一段，主要来源于深凹带阜一段烃源岩。

The intensity ratio of TO and LO inMCT was observed to be different. Such difference was explained in terms of the different Ramangeometry arrangement.〓. The laser-induced micro-photoluminescence in the range of 1000～5000〓(1.34eV～1.83eV) was found for the first time in LPE MCT epilayer. The center of photoluminescence wasat 2750〓 or 1.62eV and the FWHM of luminescence was 2000〓 or 0.25eV. We assume thatthe photoluminescence is due to recombination of electron from an anion vacancy resonance levelto the top of valance. In addition, new Raman shift was observed at 750〓 in LPE MCTepitaxial film.〓. The laser-induced micro-photoluminescence with quasi-periodic structure was observed forthe first time at room temperature in one of MOVPE MCT epitaxial film samples. The range offluorescence was from 1.46eV to 2.21eV, i.e., 1.73eV above the conduction band edge.

2首次在LPE生长的碲镉汞外延薄膜的显微Raman谱中，在1000～5000〓范围发现了激光激发显微荧光，该荧光的发光范围换算为电子伏特标度为1.34eV～1.83eV，荧光的发光中心大约位于2750〓，即1.62eV，发光的半峰高宽约为2000〓或0.25eV；指出该显微荧光来源于碲镉汞薄膜中的阴性离子空位共振能级的激光激发发光；观察到了碲镉汞外延薄膜中一个新的Raman散射峰，位于750〓位置； 3首次在一块用MOVPE方法生长的〓Te外延薄膜的显微Raman谱中，发现了1.46eV至2.21eV范围并伴随有周期结构的显微荧光峰，该发光峰对应的能带中心位于〓Te材料导带底上方1.73eV，通过研究得出样品在1.46eV至2.21eV范围的显微荧光峰是由于改进 MOCVD 生长工艺，提高了碲镉汞外延薄膜的结构质量所致；通过分析指出该显微荧光来源于外延层中的阴性离子空位的共振能级发光。

The pathological signs analogized to human VOD were found in nine mice, six from the experimental group and three from control.

有9只小白鼠病理组织检查中，出现和人类似的符合VOD诊断标准的表现；其中6只来源于实验组，3只来源于对照组，2组之间差异无统计学意义。

In order to investigate the source of nucleic acid in the sera of host infected with S. japonicum, single or dual sex cercariae of S. Japonicum infected mice models were set up for further research.

结果初步证实在日本血吸虫感染早期，血清中的核酸物质可能主要来源于移行过程中死亡的童虫以及虫体发育过程中更新脱落的表皮组织，而在感染的急性期和慢性期，小鼠血清中的核酸物质可能主要来源于虫卵的分解产物。

That is, U-enriched muscovite peraluminous granites are the uranium source for metallogenesis, and the uranium is mainly devided from the parent granite rocks weathered and denudated, not from the hydrothermal solution derived from the parent granite rocks.

即铀含量较高的晚期二云母过铝质花岗岩是铀成矿作用的铀源，而且，铀源主要来源于被风化并剥蚀掉的那部分母岩，而不是来源于热液流体对现存母岩的交代。
