Combined with available data, it is comidered that the sourcerock of biotite--leptynite might be intermediate-acid volcanic material of ca.2.7 Ga, and that of migmatized leptite and quartzite might come from granitic crust older than 3.0 Ga. The iron formation was formed on the continental crust base at about 2.7 Ga, and was immediately metamorphosed for the first time.

结合已有的研究资料可以认为，黑云变粒岩的原岩来自2.7 Ga左右的中酸性火山物质，浅粒岩和石英岩的原岩来自3.0 Ga以上的花岗质地壳物质；含铁建造形成于陆壳基底之上，形成时间约2.7 Ga，并于2.5—2.7 Ga之间发生首次变质作用。

These are prepared with little or no heat treatment, and major spoilage can be caused by Lactobacillus and Leuconostoc spp., which produce diacetyl-butter flavors.

We divide the evolution of becoming rocks into four periods: early region's metamorphic process and mixed lithifaction,sedimentation and becoming rocks process in middle and late Proterozonic Era and in the Paleozonic Era,trasformation process of burial hill layers in earth shell'uplift period in the Mesozonic Era, and transformation process to burial hill in the Cenozonic Era.

将储层的成岩演化划分为四个阶段：即早期区域变质作用和混合岩化作用、中晚元古代和古生代沉积成岩作用、中生代地壳抬升阶段潜山地层的改造作用和新生代断裂对潜山的改造作用。

The implication,charters,studying method and important point of fluid,present situation offluid studying and its developing level at home and abroad,and important means of relation-ships of fluid with plate structure ,metamorphism,lithogenesis and mineralization have beenelaborated in the paper.

本文阐述了当今国内外流体的研究现状、发展水平、流体的涵义、性质、研究方法和研究重点及其与板块构造、变质作用、岩浆作用、成矿作用、成矿作用的重要意义。

During the subduction and collision of Yangtze and Sino-Korean craton in Triassic period, they all subduced into mantle depth, due to the granite was relative poor in water and denser than sedimentary rocks, the kinetics rate of metamorphism of granite was much more slow than that of sedimentary and mafic volcanic rocks.

即在扬子板块与中朝板块三叠纪俯冲—碰撞过程中他们一起进入到地幔深度的超高压环境，但由于花岗片麻岩的原岩相对于副片麻岩的原岩明显贫水且结构致密，其中发生变质作用的动力学速度明显慢于沉积岩或基性火山岩中的动力学速度。

This offers important information for the study of magmatic event and tectonic environment in the area.

识别和解体出的这些变质花岗岩类，为进一步研究祁连和北秦岭两大构造单元的岩浆事件和构造演化提供了十分重要的信息。

Xiuyu formed in magnesian carbonate rocks in metamorphic marble, China's such a lot of jade kinds of deposits.

岫玉形成于镁质碳酸岩的变质大理石中，我国这种玉种的矿床很多。

We suggest that the shocked meteorites could be classified into two groups; the group-A contains high-density phases, such as maskelynite and other high-pressure minerals; the group-B contains low-density phases, for instance diaplectic feldspar glass, molten glass and the assemblages of low-pressure minerals.

本文提出，陨石按照冲击变质特征可以划分为以下两类：一是含高密度相类，如熔长石和各种高压矿物；二是合低密度相类，如长石击变玻璃、低压熔融玻璃和低压矿物组合。

The result shows that modification can make the β-Si phase thin when the joining amount is 0.3wt%, making the best modification result. Alloying elements Mn and Ni are always used to neutralize iron"s harm in aluminum alloys. They can form many kinds of complicated metallically compounds with Fe and Al, and eliminate needle-like iron-rich phases to reduce iron"s harm in Al-Fe alloy. Copper makes the alloy microstructure thick and electromagnetic stirring obviously makes the alloy microstructure thin, round the second phase, when the stirring voltage is 200V, making the best result; Reheat makes liquid phases emerge in the alloy, when the warming temperature is 650?

研究结果表明：红磷可以明显细化合金中的初晶硅，当加入量为0.3wt%时，取得最佳变质效果；锰、镍合金中加入后，通过形成多种复杂金属间化合物，细化针片状富铁相，减小铁对铝硅合金性能的危害；铜使合金微观组织发生粗化；电磁搅拌明显细化合金组织，使第二相圆整化，搅拌电压为200V时，取得最佳细化效果；二次加热使合金组织中产生部分液相，在650？

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
