As a result,the venations of Mylabris Fabricius were tentatively classified into three types as follows:Southern type,represented by Oriental species,wing dark brown with a lot of folds,veins stout and highly sclerotic;Plateau type,represented by Qingzang Plateau endemic species,wing ivory-white and semitransparent,only the large cell enclosed by costal margin and MP_ 1+2 obvious;and Northern type,as the transition between the former two types,represented by Palearctic species,wing brown,veins clear and moderately sclerotic.

研究结果将斑芫菁属翅脉归纳为3种类型：1南方型：东洋种，翅深褐色，各脉粗大，骨化程度高，皱褶多而明显；2高原型：青藏高原特有种，翅乳白色，半透明，仅前缘和MP1+2形成明显的大翅室，余脉淡而不显，骨化程度低；3北方型：为以上两种类型的中间过渡，古北种，翅褐色，各脉清晰，中度骨化。

Based on the regional tectonic evolution, combined with the high precision isotopic ages from this paper and other geologists, we have some new acquaintances as follows: 1 There has no Caledonian granite belt distributed in north margin of North China Craton. So, the traditional evolving model of North China Carton, which formed on this idea and the acquaintance about the collision of North China plate and Siberian plate, must be incorrect; 2 The age date show that the earliest magmatic activity began since late-Palaeozoic Permian, which is inconsistent with the previous idea that there were Caledonian and Hercynian active continental margin in the north of North China Craton and in the south Xingkai Massif. 3 the crust and lithosphere were thickened by the subduction and collision of Siberia plate and North China plate during Late Paleozoic. The magma is formed when the crust is heated and melts caused by thickened lithosphere delamination and caused the Asthenosphere upwelling. But only a little basaltic magma erupted, most magma underplate under the bottom of the crust. Thermal energy derived from basaltic magma underplating made the middle and lower crust melt partially and the late Permian-early Triassic granites is formed in large scale.

根据区域构造演化分析，并结合本文及他人高精度同位素年龄，我们对延边花岗岩形成的大地构造环境有了新的认识：1在华北地台北缘并不存在所谓的加里东花岗岩带，因此，建立在此之上的传统的华北地台北缘演化模式及有关西伯利亚板块与华北板块的碰撞拼合的认识也必然是不正确的；2华北地台北缘和兴凯地块南缘不存在加里东期和海西期花岗岩带，表明两地块边缘最早的花岗质岩浆活动始于晚古生代的二叠纪，即不存在传统观点所认为的加里东期或海西期活动陆缘；3晚古生代由于西伯利亚板块与华北板块的俯冲碰撞，致使地壳和岩石圈增厚，导致加厚岩石圈发生拆沉作用，使得软流圈上涌，加热地壳使之熔融形成岩浆，但玄武质岩浆少量喷出地表，大部分底侵于地壳底部，形成下地壳高密度的玄武质底侵层，玄武质岩浆底侵的热能引起中下地壳广泛部分熔融，形成大面积分布的晚二叠世—早三叠世花岗岩。

in the long-term of the education teaching process, the head quarter appear a student study effect of two pole divide phenomenon, divide "learn excellent living" and"learn to trap to living" is two greatest categories, particularly learn to trap living of the problem be more and more valued by the large teacher.aim at this phenomenon, my school specialized establish a topic research group, the theories background and material background that is from the topic 2 carry on analysis study, try hard for to make track for a root to trace to origins, find out some more practical viable way, scoop out learn to trap living of intelligence potential, exaltation study interest, contract a student study the margin of effect.

在长期的教育教学过程中，总会出现学生学习效果的两极分化现象，分化出&学优生&和&学困生&两大类别，尤其是学困生的问题越来越受到广大教师的重视。针对这一现象，我校专门成立课题研究小组，从课题的理论背景和物质背景两个方面进行分析探讨，力求追根溯源，找到一些比较切实可行的办法，挖掘学困生的智能潜力，提高学习兴趣，缩小学生学习效果上的差距。

PGE analyses for the picrites of the middle Devonian Beitashan Formation at the south margin of Altai Mountains show that the PGE concentrations are within a narrow range, and their primitive mantle normalized PGE patterns resemble those from Grenada picrites, Lesser Antilles Arc in Atlantic, which is characterized by the enrichment of PPGE although the PGE contents of the researched picrites are higher than the latter, and lower than those from large igneous provinces.

本研究对新疆阿尔泰山南缘中泥盆世北塔山组地层中的苦橄岩的铂族元素进行了分析，结果表明：其铂族元素的含量总体变化不大，其原始地幔标准化曲线总体上和已经报道的大西洋Lesser Antilles岛弧的Grenada苦橄岩相似，均以富集把组铂族元素为特征，但总体含量比后者高，而比大火成岩省的苦橄岩低。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
