A good many mico-landblock of the early Neoproterozoic-Cambrian volcanic rock that distribute in the Tianshan orogenic belt and on its both sides, and the Carboniferous-Permian volcanic rocks that widely distribute in the Tianshan and adjacent regions are selected for subject investigating in this paper. Renewing the ocean-land format and ocean-land conversion process of Tianshan orogenic belt in the Paleozoic is the masterstroke for this paper. On the basis of detailed field investigation, many subjects, such asregional lithology、geochemistry、structural geology、volcanic sedimentology geology、sotope geochronology and synthesis analysis study of geophysics data, are adopted as instrumentality in the paper, this study lays emphasis on the formation, evolution and dynamics of early Neoproterozoic-Cambrian and Carboniferous-Permian volcanic rock in the Tianshan and its adjacent regions to find out Carboniferous-Permian volcanic rock property, eruptive sequence, time and space distribution characteristics, to resume and reconstruct evolution process of Carboniferous-Permian volcanic rock, and to explore connection of magmatism process and lithosphere stretching action of neopaleozoic ocean-land transformation in the Tianshan region.

According to Two Factor Theory of Frederick Herzberg, it can only remove a employee's dissatisfaction of wage and working conditions, but it has no incentive effects, instead, the stimulation are only contributed by the work itself and the sense of responsibility to the work suchlike incentive factors.

根据赫兹博格的双因素理论，工资和工作条件的满足只能消除员工对工作的不满情绪，并没有激励的作用，而起激励作用的是工作本身和对工作的责任感等激励因素。

Manini, MD, from Harvard Medical School in Boston, Massachusetts, and colleagues."Cardiovascular adverse effects can occur, including hypertension, arrhythmias, prolongation of the QT interval, and angina pectoris. Dangers of over-the-counter sympathomimetic use are illustrated by the recent ban on dietary supplements containing ephedrine alkaloids by the US Food and Drug Administration because of increased risk of sudden death, acute myocardial infarction, and stroke."

Manini医师表示，Pseudoephedrine是ephedrine的镜面异构物，会产生肾上腺素的综合促效作用，一般被用来作为解充血剂；此药的副作用包含高血压、心律不整、心电图QT波间距延长及心绞痛等；最近，美国食品药物检验局规定添加剂不得含ephedrine生物碱，由此可看出仿交感神经作用的药物所潜藏的危险；这些危险包含猝死、急性心肌梗塞及中风等。

The research has shown that the ourgassing of the Earth can be regarded as a key link,which connects the separated branches of the Earthscience into a whole mega system The essence of Earth outgassing is the expelling of mantle ichorspontaneously and radiately from the interior of the Earth,resulting in five gas spheres and gas geodynamics The upwelling of HANCONS makes the solid mantle and crust to ulcerate by the alkaline mesomatism,alteration and magma formation, and the ...

To understand whether the GST can protect plant from the damage of ultra-violet radiation,a UV inducible GST gene was isolated from an Arabidopsis cDNA library.The plant expression vector containing the GST cDNA was constructed and transferred into Arabidopsis thaliana plants by the Agrobacterium-mediated vacuum method.Molecular genetic analyses showed that the overexpression of the UV inducible GST could increase the tolerance of the transgenic plants to UV radiation

为了阐明GST在紫外辐射下是否对植物有保护作用，以紫外强烈诱导表达的GST cDNA为探针，筛选拟南芥cDNA文库，获得了这种GST的全长cDNA；利用此cDNA构建植物表达载体，并通过农杆菌介导法转化拟南芥，使其在拟南芥中得到大量表达；通过对转基因植株的紫外辐射耐性分析，证实了该GST的过量表达可明显增强拟南芥对紫外辐射损伤作用的耐受性。
