The study shows that in various continental downfaulted basins in eastern China,the China East Sea basin of the southeast sea region and the continental shelf—Qiongdongnan basin and Zhujiangkou basin—of the northern South China Sea,CO2 in CO2 reservoirs and CO2-rich oil/gas reservoirs is of typical volcanic mantle-derived type and that its migration and concentration is mainly controlled by mantle-derived volcanism and gas-conducting distribution of deep basement faults connected with the gas source at depth. CO2 is mainly sourced from substantial amount of CO2 associated with mantle-derived volcanism at the deep level of the crust. CO2 in the CO2 reservoirs and CO2-rich oil/gas reservoirs in the Yinggehai basin on the continental shelf of the northern South China Sea is of crust origin and crust-mantle mixing origin and mainly controlled by local,layer-by-layer and zone-by-zone,multiple intrusion of late hydrothermal fluids in mud diapir areas and physico-chemical processes of very thick Pliocene-Miocene marine calcareous sandstone and mudstone.

研究表明，中国东部陆上诸断陷盆地与东南沿海海域的东海盆地及南海北部大陆架琼东南盆地和珠江口盆地CO2气藏及高含CO2油气藏中，CO2均属典型的火山幔源型成因，其运聚富集主要受控于幔源型火山活动与沟通深部气源的基底深大断裂的导气配置作用，CO2气源主要来自地壳深部幔源火山活动伴生的大量CO2；南海北部大陆架西区莺歌海盆地CO2气藏及含CO2油气藏中的CO2，属于壳源型及壳幔混合型成因，主要受控于泥底辟热流体晚期分层分块多期的局部上侵活动与沉积巨厚海相含钙砂泥岩的物理化学作用，其运聚分布具多期和分层分区的特点。

Hence, the study on planetary volcanism is a key part of comparative planetology. Study the volcanism of celestial bodies of Solar system could provide significant knowledge for the understanding of the formation and evolution of the planets, deep and surface processes, metallogenesis, and initiation of life.

对太阳系天体火山作用的对比研究能够提供认识太阳系和行星演化、天体深部和浅部地质作用过程、矿产资源形成以及生命的起源和演化等重要信息，是比较行星学的重要组成部分。

The clay mineralogy composition and clast composition difference between different section or different levels in one section may result from variable intension of the volcanism, distance from the volcanism center and paleogeographical location.

同是深水相P-T界线剖面附近的黏土岩以及同一剖面不同层位的黏土岩中的黏土矿物和碎屑物质存在较大的差异，其原因可能是与火山作用的强弱、离火山活动中心的远近以及所处地理位置有关。

Holocene"periglacial phenomena"were found at many places continuously. However, by comprehensive study, this thesis believes that these"periglacial phenomena"are almost the results of seasonal freeze-and-thaw action, not the strict periglacial phenomena. Only in some high mountain areas and northeastern zigzag zone of farming and animal husbandry, there were periglacial phenomena developing conditions in the cold stage of the Holocene.

我国北方农牧交错带全新世的&冰缘现象&不断有所发现，但本文经过综合研究后认为，这些&冰缘现象&绝大部分都是季节性寒冻作用的产物，而非严格意义上的冰缘现象，只有局部中高山地区和北方农牧交错带东北部现代气温在0℃以下的地区，全新世低温期才具备发育冰缘现象的条件。

This paper to introduce a new experimental method of dispersion phenomena, in this experimental method, it can be directly observed by different substances uneven medium, the dispersion arising from the various phenomena of the material in different light source through uneven medium, the emergence of two different spectral dispersion surface, spectral noodles Bright (Bright-Line Spectrum), and dark lines is how it is formed and a series of important experimental phenomena.

本文要介绍一种新的色散现象出现实验方法，在这种实验方法上，可直接观察到不同物质通过不均介质后，所出现的各种不同色散现象，物质在不同光源照射下通过不均介质后，出现的两种不同色散谱面，谱面中明线和暗线是怎样产生等一系列重要实验现象。

Based on the experimental simulation studies on the boilover phenomena using different scale oil tanks and various kinds of oil, the basic characteristics of boilover were analyzed. And then, more attention was paid to the typical sub-processes in boilover such as (1) the fire behavior during boilover,(2) the thermal structure in oilwater layer,(3) the generation, growth and moving process of vapor bubbles on the oil-water interface and in the oil layer,(4) the premonitory micro-explosion phenomena of boilover and its noise aspects,(5) vapor explosion phenomena on the oil-water interface,(6) the burning rate of oil and etc.

在运用中、小尺度模型油罐和多种实验油品，对扬沸火灾现象进行模拟实验研究的基础上，分析了扬沸火灾的基本性状，着重考察了扬沸火灾过程中的一些典型分过程：（1）扬沸火灾的火行为，（2）油水层热结构特性，（3）在油界面上及油层中的蒸汽泡形成、长大、运动特性，（4）扬沸前兆燃烧微爆现象及其噪声特性，（5）油水界面上的蒸汽微爆现象，（6）油品的燃烧速率等。

During the motion process, the stagnation and back commutation occur and worsen the performances of circuit breaker. According to the real interruption process, a three-dimensional(3-D) model of arc motion under the effect of external magnetic field is built based on magnetohydrodynamic, which can predict the restriking phenomena. With air vents opened to 60%, the restriking phenomena occur under 3mT magnetic field; when the magnetic field is increased to 5mT, the restriking phenomena disappears.
