Our investigation shows that neither the dioritic porphyry nor the sedimentary rock is the source of iron ores, and that the source of most ironrich orebodies is the ore magmahydrothermal system in the deep chamber. Ore magma which was formed by liquid immiscibility is the main source of Gushan deposit, and the residual ironrich hydrothermal fluids which occurred as NaFeCl complex is the main source of Baixiangshan deposit.

根据野外观察和地球化学研究，文中认为，闪长玢岩岩体和沉积围岩均不是铁质的主要来源，富铁矿体的成因主要来自矿田深部的矿浆热液系统，姑山式铁矿的铁质主要是液态不混溶作用形成的铁矿浆，白象山式铁矿的铁质主要来源于深部残浆分离出的NaFeCl络合物。

As open a source to warm up in global abidance, there also are more and more people to never had known a cause in China, use Linux to the attempt, development becomes the lover of the source, champion, the opportunity that meets through meeting this, they experience the intendment of the source more deep-feltly, experience the glamour of the source.

随着开源在全球的持续升温，在中国也有越来越多的人已经从不知道开源，到尝试使用Linux，发展成为开源的爱好者、拥护者，通过这次见面会的机会，他们更深切地体会到开源的真意，感受到开源的魅力。

Furthermore, the theory foundation and analysis method are put forward. We use optical extent to analyze the system. The change of optical extent, caused by arc length of light source and reflective bowl attached the light source, is analyzed in detail. Moreover, the light output by optical extent curve of light source with reflector is measured by experiment. Base on the analysis and experiment, four hypothesis are put forward to construct the true model of light source.

文中采用光学扩展量对系统进行评价分析，研究了光源经冷反光碗输出后的光学扩展量以及光源弧长与扩展量之间的关系，并测试了实际光源光学扩展量与能量分布的关系，在实验基础上提出光源模型的四点假设，建立实际体光源模型及冷反光碗模型，使系统的模拟仿真具有最大的可靠性与真实性。

This paper analyzes the numerical control DC constant current source system design needs, expounded numerical-controlled DC constant current source of the hardware and software design principles, instructed the numerical-controlled DC constant current source circuit of the module function and design ideas, completed the numerical-controlled DC current source of all design, and the circuit is complete and procedures.

本文主要分析了数控直流恒流源系统的设计需求，阐述了数控直流恒流源的软硬件的设计原则，介绍了数控直流恒流源各模块电路的功能及设计思路，完成了数控直流恒流源系统的全部设计，给出了完整的电路图和程序。

So, when using source software, when needing to be based on source software to undertake commerce is developed especially, after choosing what should use to open source software, run from opposite directions with respect to need source software licence undertakes study, need understands his to permit regulation, right from already sequel is developed and use whether limitation undertakes study.

所以，在使用开源软件时，特别是需要基于开源软件进行商业开发时，圈定要使用的开源软件后，就需要对开源软件许可证进行研究，需要了解其许可规则，对自已的后续开发和使用是否有限制进行研究。

By means of field survey, systems analysis and history datum analytic methods, on the base of natural, social, economic conditions of the source region, the author analyzed the type, characters of vegetation of the source region, then aimed at the problems of produce in source region, and then took out thereinafter conclusions on studying approaches to sustainable utilization of grassland in the source region.

本文通过实地调查、系统分析、历史资料分析的方法，在阐明江河源进行草地生产的自然、社会、经济现状基础上，分析了江河源区植被分布的类型及特点、江河源区草地退化原因，并针对江河源区草地生产存在问题，提出了江河源区草地可持续利用的途径。

The source of the Tsushima Warm Current will change in the year: in January and February the main source is the flow from the Kuroshio; from March to August, the main source gradually changes from the Kuroshio to mixed water of the flow from the Taiwan strait and the Changjiang diluted water; after August, the main source changes back to be the Kuroshio.

对马暖流的来源全年均有所变化，一、二月以黑潮水为主；三月到八月，来源逐步从黑潮水转变为台湾海峡北上海流以及长江冲淡水的混合水；八月到九月，来源重新转变为黑潮水。

Maturity of Lower Cretaceous source rock, researched by the authors, is closely relative to the deposition thickness of the Tertiary and the Quaternary. It shows that source rock at the depth of 4,000-4,400m is low mature, and 4,400-5,200m is in the peak of oil generating. Correspondingly, the source rock of the Zhonggou Formation is immature; the Upper Xiagou Formation is low mature; and the Lower Xiagou Formation and the Upper Chijinpu Formation are in the peak of oil-generating; and the Lower Chijinpu Formation is at the stage of generation of condensate-wet gas with high maturity. There is no source rock reaching the overmature stage of dry gas at present.

可溶有机质转化率、镜质体反射率、热解、生物标志物特征等参数表明：青南凹陷中部的下白垩统烃源岩生油门限深度为4000m（相应的镜质体反射率为0.65％），埋深4000～4400m为低成熟阶段，埋深4400～5200m为成熟生油高峰阶段，因此中沟组烃源岩未成熟，下沟组上部烃源岩低成熟，下沟组下部和赤金堡组上部烃源岩处于成熟生油高峰阶段，赤金堡组下部烃源岩处于高成熟的凝析油—湿气阶段，目前尚无烃源岩达过成熟干气阶段。

Sterane and terpane biomarkers of Lower Paleozoic source rocks in the Tarim basinindicated that there is closer relationship between crude oil and the Cambrian source rocksrather than the Middle-Lower Ordovician source rock, and less relation with UpperOrdovician source rocks.

4烃源岩甾萜烷生物标志化合物特点表明，寒武系烃源岩与原油最为接近，次为中、下奥陶统，上奥陶统最疏远。

According to several source rocks and many regions of generation, transportation, accumulation in the East of LinQing depression, the author compartmentalizes the petroleum systems of the East of LinQing Depression by two points: The first is taking hydrocarbon source rock as a core to name by hydrocarbon source rock and reliability, and the second is taking secondary structure unit containing the possible area of generation, transport and a〓umulation of oil and gas as a core to name by source rock name and structure unit name and reliability.

结合临清坳东部存在多层系烃源岩、多个油气生成运移聚集区域的特点，对临清坳陷东部的油气系统按二个层次进行了划分，第一个层次以烃源岩为核心，用烃源岩+可靠性来命名；第二个层次以次级构造单元为核心，包含了油气生成运移聚集的可能区域，用源岩名+构造单元名+可靠性来命名。

The dissecting of samples in group2 were difficult. The root of pulmonary artery and ascending aorta failed to be unfolded because fibrous tissue was tough, right and left fibrous trigone were too firm to be solved by hand. Cardiac muscle fibers couldn't be stripped along myofibrillar trajectory since they were prone to break because of their friability.

组2的心脏解剖困难，表现为纤维组织坚韧，游离肺动脉非常困难；徒手无法松解左、右纤维三角，肺动脉和主动脉根部的游离非常困难；心肌纤维坚硬、质脆，解剖时容易断离成碎块，无法沿纤维走行方向剥离。

We have battled against the odds in a province that has become increasingly violent.

我们对在一个争夺日益激烈省的可能性。
