Because the main territorial cap rock which could block off hydrocarbon migration in another side of fault in Paleozoic stratum is huge thick mudstone in upper mbr of Shangshihezi group and Shiqianfeng group, this make only backward fault to dip direction can block to form fault-block trap in the reservoir stratum of carbonatite eluvial horizon in Ordovician and thick sandstone in Permian .

古生界具有侧向封堵条件的区域性盖层主要是上石盒子组上段—石千峰组大套泥岩，这决定了断块区奥陶系碳酸盐岩风化淋滤带及二叠系大套砂岩储层在反向断层遮挡下能形成断块圈闭。

The mechanism in which trehalose is produced from dextrin or starch hydrolyzate by endocellular enzymes of bacterium D-97 can be elucidated by high performance liquid chromatography with differential refraction detection basically, including the effect of the different carbon sources on the endocellular trehalose-producing enzymes in bacterium D-97 and the possibility or ability of the endocellular enzymes to produce trehalose using maltooligosaccharides of different chain lengths.

Lastly, based on analysis on phylogentic relationships among 39 ciliates combined with their main morphologic characters, some conclusion were drawn: 1 the monophyly of the peritrichs was strongly supported, and its subclass rank in the class Oligohymenophorea is reasonable; 2 the genus Epistylis might not be monophyletic, and the peristomial area, especially the peristomial lip, might be an important phylogenetic character within the genus Epistylis; 3 the taxonomic rank of the genus Carchesium and the genus Campanella were suggested to be adjusted; 4 Opisthonecta probably diverged from peritrichs with stalks; 5 the phylogenetic tree of peritrichs was reconstructed based on the molecular information inferred from SSrRNA gene sequences and the morphology.
