This study showed that population genetic diversity was much lower than other Gymnosperm and there was no distinct genetic differentiation among individuals in this population. In order to protect or preserve its genetic resource,it is suggested that the most individuals in the population should be selected as we can.

研究结果表明：AFLP方法是一种十分有效的检测种群遗传多样性的分子标记，既具有可靠性又有方便高效性；元宝山冷杉种群的遗传多样性水平很低，种群内各个个体间的相似性系数很大，遗传关系很近，无明显的遗传分化，这说明该种群的适应能力差、进化潜力有限，濒危程度很高；若要保护或保存这个物种的遗传资源，建议应该选择种群内尽可能多的个体进行保护。

Analysis of the obtained genome amplification showed that DNA after PCR presented obvious polymorphism, and the results were the same using the same primer to amplify the larva and imago of the same species. It indicates that RAPD technique can be applied to the identification of dry samples and dipped larva sample of longicorn beetles as well as the research of phylogeny. These three methods for extracting genome DNA from different species of longicorn beetles at different preserved time are feasible.

对所获得的基因组扩增分析表明，经过PCR之后的DNA能呈现明显的多态性，同种天牛用同一引物扩增幼虫和成虫所获得的结果相同，可以认为，RAPD技术可以应用于天牛成虫干标本及幼虫浸渍标本的鉴定及系统发育研究中，也证明了这3种方法用于提取不同保存时间、不同种天牛基因组的DNA是切实可行的。

Molecular systematics on germplasm resources of oak silkworm, Antheraea pernyi , including genetic diversity, cultivar taxonomy and microevolution within species, were investigated using Random Ampified Polymorphic DNA, mtDNA sequence analysis and population genetic analysis.

The calibration curve of the SM2-Kit with standard SM2 inhibitor was typical sigmoid curve fitted to the four parameter logistic equation with the linear detection of 0.625 μg/L to 80.0 μg/L (R2=0.9911), the sensitivity of 0.9 μg/L, the IC50 of 5.82 μg/L and the detection limit of 1 μg/L. The recoveries of SM2 spiked in pig feed were 83.4 %, in pig urine were 89.5 %. The precision and accuracy of the assay as determined by inter-assay and intra-assay coefficient variation was both below 15 %. The SM2-Kit generally had 2.08 % cross-reactivity towards sulfamerazine and little or no cross-reactivity towards other sulfonamides. The dilution solution of SM2 had no effect on results of SM2-Kit. The validity of SM2-Kit in 4 ℃ was above six months.

研究结果表明，SM2-Kit的标准曲线呈典型的S型，相关系数R2=0.9911，符合4参数logit曲线拟合，线性检测范围为0.625 μg/L～80 μg/L，灵敏度为0.9 μg/L，半数抑制浓度(IC50)为5.82 μg/L，检测限为1 μg/L；饲料样、猪尿样的平均添加回收率分别为83.4 %、89.5 %，平均批内和批间变异系数均低于15 %；SM2-Kit与磺胺甲基嘧啶的交叉反应率为2.08 %，与其它磺胺类药几乎没有反应性；基质对SM2-Kit的检测结果影响不大；试剂盒在4 ℃可保存6个月。

Consistent with the idea that the monkey in Ukraine Agkistrodon IRF7 transcription activation domain to identify the sequence of the polymorphism, however, TLR7 and TLR9 has a high degree of preservation of the sequence in which both monkeys and humans.

与这一想法一致的是，在乌白眉猴的IRF7转录激活域中鉴定到了的序列的多态性，然而TLR7和TLR9的序列却高度保存在两种猴子和人类当中。

Of the 36 tussah silkworm varieties, the Nei's genetic diversity index was 0.3243±0.1515, and Shannon information index was 0.4871±0.1975, suggesting that bivoltine tussah silkworm varieties are still rich in genetic diversity even having been conserved in the same place for quite long time. Nei's genetic identity of the 36 varieties ranged from 0.4959 to 0.8347, 96.59% of which was above 0.6, revealing large similarity between different varieties. A clustering analysis showed that these varieties formed two separate clades, one of which included varieties bred by the institute and the other included imported varieties from other provinces or countries.

供试品种资源的Nei氏遗传多样性指数为0.3243±0.1515，Shannon信息指数为0.4871±0.1975，表明长期同地保存的二化性柞蚕品种资源同样具有丰富的遗传多样性；供试品种的Nei氏遗传一致性范围在0.4959~0.8374之间，达0.6以上的占96.59%，表明多数品种资源的相似程度较高。36份品种资源分别以辽宁省蚕业科学研究所育成种为主和以国内外引进种为主聚为两大类群。

During the Early Carboniferous, glacio-eustasy and the palaeogeographic environment of Qiangui intra-platform basin played crucial roles in controlling the geobiological processes, the formation and distribution of basinal facies hydrocarbon source rocks.

早石炭亚纪冰川性海平面变化及黔桂盆地独特的古地理位置控制着盆地中的地球生物学过程，决定了生烃母质生物的生产力和有机质的保存条件，进而影响了盆地相烃源岩的形成与分布。

The zonality of abnormal pressure is closely correspondent to the breakthrough pressure (or pressure preservative ability) of mudstones in the Dongying Sag. The breakthrough pressures and formation fluid pressure coefficients rise with increasing depth. The preservation of isolated mudstone intervals is also important to the abnormal pressure formation.

东营凹陷异常压力的分带性与泥岩的突破压力具有明显的对应关系，随着深度增加，泥岩突破压力及地层流体压力系数均增大，泥岩封隔层对流体压力的保存也是形成异常压力的重要条件。
