In the first, the length of every poleof the leading four-bar mechanism are determined bypainting,secondly, the base of mechanic model ofsupport-surrounding, the mechanism and loads on the support isdecided. The next work, with the condition of the design, the mainmechanics of hydraulic support is analyzed and calculated by planeand spatial model. Finally, the under frame, top beam cave shield,wrists and hydraulic column are analyzed by calculation. And drawout all the process drawings.

首先，通过作图确定支架的四连杆机构各杆系的长度；然后，以力学模型为依据，分析了液压支架的顶梁、掩护梁上载荷的作用机理，得到了较为合理的支架载荷的计算公式；其次，结合设计的支架，从平面和空间两方面对支架主要结构件进行受力分析；最后对支架主要结构件、连接销轴进行强度效核，并画出所有的机械图。

This dissertation, in the perspective of systematic theory, censors various media between "state subject" and "the educatee" in the educational process, tries to analyze its possible problems and finds effective ways to improve education.

本文运用系统观审视思想政治教育过程中&国家主体&与&受教育者&之间的各个中介环节，试图对可能出现的问题进行诊断、分析，找出提高思想政治教育有效性的突破口。

By the partial purification of Arthrobacter nicotinovorus D-97 endocellular enzymes and the results of enzymatic reaction of enzymes of partition collection, it was found that enzymes related to trehalose synthesis were consisted of Trehalose-forming Enzyme and Trehalose-releasing Enzyme . Trehalose-forming Enzyme could convert maltooligosaccharides into non-reducing maltooligosyl trehalose by intramolecular transglycosylation, and Trehalose-releasing Enzyme could hydrolyze α-1, 4 linkage between the trehalose residue and the maltooligosaccharide residue to release trehalose and maltooligosaccharides with two glucose monomer lesser.

将食尼古丁节杆菌D-97胞内酶部分纯化并对各收集组分进行酶反应，发现其海藻糖合成酶系由海藻糖生成酶(Trehalose-forming Enzyme，TFE)和海藻糖释放酶(Trehalose-releasingEnzyme，TRE)组成，前者分子内转糖基将直链麦芽寡糖转化为没有还原性的麦芽寡糖基海藻糖，后者专一切割麦芽寡糖基海藻糖分子上麦芽寡糖基与海藻糖连接的α-1，4糖苷键，从而释放出海藻糖和减少了两个葡萄糖单体的麦芽寡糖。

The efficiency of an closed epicyclic gear train is analyzed by means of this formula, some of efficient curves are drawn, and an adequate selecting range of transmission ratio is found.

推导出了动力学模型中惯性元件、弹性元件和分支节点的动力学分析的数学模型，用传递矩阵法建立起封闭周转轮系动力学分析的数学模型。

In addition, DNA methylation profiles segregated patients with CEBPA aberrations from other subtypes of leukemia, defined four epigenetically distinct forms of AML with NPM1 mutations, and showed that established AML1-ETO, CBFb-MYH11, and PML-RARA leukemia entities are associated with specific methylation profiles.

此外，根据DNA甲基化的不同可将CEBPA基因畸变与其他亚型的白血病区分开来，并定义出四个不同表型的伴NPM1基因突变的急性髓系白血病，并且表明AML1-ETO， CBFb-MYH11，和 PML-RARA 三种白血病类型与特定的甲基化有关。

Tongue tie is too short, so that should not extend extraoral tongue, the impact of the flexible tongue movement, so the impact of the larger aspects of language development, commonly known as "大舌." 2, these are caused by organic disease transformer ambiguous words; There is also a non-organic ambiguous words, 2-year-old children with limited vocabulary; but would like to use language to express the results difficult to say if a series of adults, medically known as the "insinuations", also known as the "language disorder."

舌系带过短，使舌不能伸出口外，影响舌头的灵活运动，所以对语言发育方面影响较大，俗称&大舌头&。2、上述属于器质性病变压器造成的说话不清；还有一种非器质性的说话不清，2岁小儿词汇有限；但又很想用语言来表达，结果说出一连串成人难懂的话，医学上称之为&隐语&，又称&乱语&。

For example, the phylogenetic trees constructed by NJ, ME, or MP methods basing on 12S rRNA complete sequence, indicated Falconidae branched off prior to the other avian, but the UPGMA tree placed Falco peregrine into a single branch and formed sister group with Accipitridae species and Strigiformes specie.

在基于12S rRNA全序列构建的NJ、ME和MP树中都支持隼科最早分化出一个单系群，而在UPGMA树中，隼科游隼单独形成一个分支，与鹰科、夜鹰目和鸮形目互为姐妹群。

60Co-γray was a useful mutagen in induced mutation breeding .After treated with 60Co-γray ,free-living conchocelis of wild Porphyra haitanensis were induced and represented in offsprings. Purple mutant and excellent practical characters strains were selected from a lot of gametophytic blades. Single cell clone and enzymolysis were used to propagate fast in pure strains of induced mutations.

坛紫菜野生丝状体经一定剂量60Co-γ射线辐照后，子代叶状体发生了变异，经大量培养后筛选出紫色突变体（3号Ⅰ）和经济性状优良的个体（7号Ⅰ和7号Ⅱ），通过体细胞酶解和单克隆技术快速获得诱变选育纯系，并对其主要经济性状进行了研究。

Since the analytical solution was derived under the condition of an-infinitely wide slope, the shape of parabolic sections of general grassed channel needs to be considered. This work uses the results of Hey (1979) to build the shape factor, which can be used to design a grassed channel with a parabolic section.

但因其解假设条件为无限宽敞的渠道，而一般草沟设计则常用抛物线形断面，本研究用Hey(1979)找出修正形因子之系，可应用於设计草沟之水分析。

The uniform nano-sized titanic oxide mesoporous thin film which can be coated repeatedly was prepared by adding tetrahydrofuran which acts as dispersant to micro-emulsion system consisting of water,cyclohexane,hexadecyl trimethyl ammonium bromide and butyl alcohol.
