This thesis also analyzed and summarized the characteristics of the goal system of school physical education in three stages.This thesis also analyzed and summarized the characteristics of the goal system of school physical education in our country. The emphasized part of the school physical education goals altered instantly. The goals of school physical education have been affected by non-educational factors such as competitive sports, subject-center theory, multi-way and multi-layer of school physical education development as well as educational reformation and educational ideas.In this thesis, the existing problems in goal system of school physical education of our country that was pointed out that: The shortage, solecism and the confused expression of theoretical school physical education researches.

我国学校体育目标体系的发展过程分"文革"前、"文革"时期和改革开放以来三个阶段，每个阶段学校体育目标体系各有特点：建国初期，学生的健康问题受到高度重视，增强体质被当作政治任务来要求；"文革"中，学校体育目标被极端政治化；改革开放以来，"增强学生体质"被当作学校体育的首要任务和评价标准，学校体育目标体系逐渐有了层次性区分，内容空洞的现象有所改善，学校体育目标体系的视角拓宽，学生个人需要受到重视，逐渐突出健康目标，重视测试与评估，与此同时，学校体育也受到了竞技体育发展的强烈影响。

The fourth stage is "Fine management stage," they not only put three points.

In the first part, the opinions and ideas from some main figures concerning the North-western regions in modern history; In the second part, the process of three vital stages(Yang-Wu Movement, the "New Deal" in the last period of Qing Dynasty, Anti-Japanese War) are studied, and the characteristics of each stage are generalized falling into four categories, such as: military、feudal、comprador and nation-monopoly etc; In the third part, four reasons of the low efficiency of the industrial and mineral exploration are explored, they are the dominant role natural economy, the low level of productive forces, the science and technology, lack of capital accumulation and investment, lack of systematic policies and support from the government, In a word, as Mao Tsetung said:"It"s impossible to get rich, develop industry, strengthen national defence in semi-colonel and semi-feudal China.

全文共分四部分，第一部分论述了近代一些主要的阶级关注西北的言论和思想；第二部分对西北近代工矿业开发的三个最重要的阶段，即洋务运动时期、清末"新政"时期、抗日战争时期的开发过程做了梳理，并对每一个阶段的特点做了初步地概括，大致可以归纳为军事性、封建性、买办性以及国家垄断性等；第三部分对西北近代工矿业开发成效不高的原因做了论述，主要有四点：第一，小农业与家庭手工业紧密结合的自然经济占统治地位；第二，生产力水平低下，科学技术落后；第三，缺乏资金的积累和投入；第四，缺乏政府系统的政策支持和保障。

The material for formation of the granitoids isderived from mixing sources of crust and mantle, with decreasing in crust-derived componentsfrom early to late.5. The tectonic setting for formation of the Mesozoic granitoids in the region isdefined as a post-collisional setting. The occurrence of a small part of rocks with characteristics ofcollisional or anorogenic granitoids provides evidence for the continuous process oftransformation of tectonic regime from collisional through post-collisional to anorogenic.6. Themultiple cycles of mantle-derived magma underplating caused by the multiple stages oflithospheric thinning in the Mesozoic result in the partial melting of middle to lower crust orcrust-mantle syntexis to form magmas. The crystallization of these magmas emplacing afterfractionation is responsible for the formation of the Mesozoic granitoids in this region.

形成花岗岩类的成岩物质来自壳幔混源。5、河南省西部地区中生代花岗岩类成岩构造环境为碰撞后环境，部分岩石具有碰撞期或非造山期花岗岩的某些特征，表明碰撞后阶段既是碰撞造山过程的延续，又是向非造山环境的构造转换时期，因而其岩浆活动在一定程度上仍然继承了碰撞前消减时期和碰撞时期已经活化的岩浆源区性质。6、研究表明，区内中生代多阶段的岩石圈减薄作用引发多旋回的幔源岩浆底侵以及中下地壳的部分熔融或壳幔同熔，由此形成的岩浆经分异演化后侵位可以形成区内的中生代花岗岩类。

In the study, Lisa Sprod of University of Northern Colorado in Greeley and colleagues asked 4296 women to recall their physical activity levels during four key stages of life: 10 to 15 years old, 15 to 30 years old, 30 to 50 years old, and 50 years old and older.

在这项研究中，北科罗拉多大学的Lisa Sprod和她的同事们要求4296名妇女回忆她们在人生四个重要阶段的运动量。这四个阶段分别是10——15岁、15——30岁、30——50岁、50岁及50岁以上。

It was difficult to control structure stability, safety, precision, antideformation preset and deformation in construction. Based on attention points, construction method was introduced, that was two cantilever towers being installed separately and extended ladder by ladder, then two cantilever parts were closured at high altitude.

The aptitude and career interest were considered as the two dimension of the entrance guide system, and was proof-tested by the structural equation model, which results supported this two-dimension hypothesis. Accordingly, there were two parts in the guide system. One part was about the aptitude test, consisted of seven subtests: verbal reasoning, spatial imagining, mathematic reasoning, computer capacity, abstract reasoning, physical knowledge, and sentence recomposing. The other part was about the career interest test, including eight aspects: career longing, curriculum desire, entertainment after school, activity preference, job preference, work environment preference, self-estimate of one\'s abilities, and discuss future with someone else. After three times modification and testing, the psychometric indices of the guide system were become well and stable. Furthermore, the guide system was primarily launched into applying, with four typical case studies, the practicability and serviceability of the guide system was showed swiftly.The entrance guide system for junior high school students that was developed in this research was one-upping in the entrance guide field in China.

第二阶段是初中生升学指导系统的研制阶段，以能力倾向与生涯兴趣这二元因素作为初中生升学指导系统的基本架构，经验证性因素分析表明该二元架构是合理并可接受的；其中能力倾向部分共包含语言推理、空间想象、数学推理、电脑能力、抽象推理、物理知识、语句重组等七个分测验，生涯兴趣部分则包含生涯梦想、课程兴趣、课余爱好、活动偏好、工作内容喜好、工作场所喜好、能力自评、与他人讨论未来等八个方面；通过三次修改与测试，结果显示所研制的初中生升学指导系统有着良好的测量学指标；此外，通过对初中生升学指导系统的初步应用研究，并结合典型个案的深入剖析，进一步表明所研制的初中生升学指导系统具有实用性、操作性强的特点，所得结果也可靠可信。
