Supporting type is suggested to be developed into 3-prop to improve adaptability besides 2-prop and 4-prop. The difference of caving difficulty degree of coal seam is the base of caving coal method at high, medium and low position. Caving with small step and open caving flashboard used widely not only cause serious mixture of coal and rock but also hinder the improvement of top coal recovery. So we suggest caving with large step or closing caving door. Four-bar-mechanism of hydraulic support restricts development of new style caving powered support. Stabilization framework of expansion link and all-shield caving tail beam at high, medium and low position are introduced here.

支架支护型式，除了两柱、四柱以外，建议开发三柱支架以改善适应性；煤层冒放性的差异，是高位、中位和低位放煤方法存在和使用的依据；目前广泛采用的小步距放煤和开放式放煤插板不仅造成严重混矸漏矸，也妨碍顶煤回收率的进一步提高，建议采用大步距放煤和可关闭放煤口；液压支架四连杆稳定机构，制约了新型放顶煤液压支架的开发，介绍了液压支架伸缩杆稳定机构及全掩护拖移高位、中位和低位放煤尾梁。

High quality football boots are generally made from soft hides and less expensive versions from synthetic materials.

一般来说，高质量的足球鞋一般都采用柔软的皮革，一些稍微便宜的款式采用的是合成的材料。

The reason why quaternion is used in flight simulation of fighter aircraft and the geometric meaning of quaternion are described,according to axis system used in flight simulation of fighter aircraft in China,three problems are introduced as follows:(1) quaternion kinematic equations,(2) relationship of quaternion and coordinate transformation matrix,(3) Euler angles in terms of quaternion.

阐述了在战斗机的飞行仿真中采用四元数的原因和四元数的几何意义，并按照中国战斗机飞行仿真中采用的坐标系，介绍了三个问题：四元数运动学方程；四元数与坐标变换矩阵的关系；用四元数表示的欧拉角。

It proposes"the method of Chinese input with the combination of word and sentence"and discusses its feasibility and its rationality from different points of view. It puts forward concepts of active word and stable word and then it discusses an ideal pattern for homophonic word recognition with the use of this input method.

提出"词和句相结合的汉语键盘输入形式"，从不同的角度论述该形式的可行性和合理性，提出了活性词和固定词的概念，然后论述了在采用该输入形式下，同音词识别所采用的理论模型。

The hydantoin convert enzyme used in this essay is D2 hydantoinase, which has very high convert activity for D2 hydantoin. Therefore, if the used process of conversion do not occur the enzyme, the racemizatoin of hydantoin will be a speed limited step for the process that hydantoinase produce optical active amino acid.

本文采用的海因转化酶系中所含为 D2海因酶，对D2海因的转化活性非常高，由此可见，如若采用的转化体系中没有消旋酶的存在，则海因的消旋成为海因酶转化生产光学活性氨基酸的一个限速步骤。

By using the least square method and the weighted functionmethod of nonparametric estimation together, this paper defines the wavelet estimators of β and g.

本文采用了半参数估计常用的办法之一——最小二乘法结合非参数权函数估计法定义了参数分量和非参数分量的估计，这里的权函数不是通常所采用的核权函数或近邻权函数，而是由小波方法所得到的权函数，我们称它为小波权函数。

Instead of using the traditional noise mitigation techniques which rely upon materials science applications of constructing sound baffles or using sound absorbing liners, novel use of light-weight materials and sand bags had successfully controlled the sound overspill.

对此，代替传统上通常采用的依赖于声屏障的降噪技术或采用吸声内衬的方法，利用新的轻质材料和沙包成功地控制了这次音乐会的声溢出。

We use DNAMAN4.0 to structure the tree among Reindeer and Sika deer and Red deer.

本次试验采用分子生物学鉴定的方法，对雌、雄驯鹿茸的SRY基因进行扩增，从扩增的图像可以看到，我们采用的引物能够准确的对雌、雄驯鹿茸进行区分。

And Loading DLL is used in the operation of dynamically loade d ,DLL library of function calls is used in the base class function to set up virtual interface,then indicators such objects such Lane called the virtual function to achieve the right type of derivative function call to realize the idea.

其中加载DLL库时采用的是运行是动态加载；对DLL库中函数的调用是采用在基类中设置虚函数接口，再通过该类对象指针调用这类里的虚函数来实现对派生类中的函数的调用的思想来实现。

The coupling mechanism, frequency domain characteristics and propagation rule of three propagation paths of partial discharge signal

该方法所采用的测量频段较高，抛弃了以往定位方法中常用的"慢波"，不会受到窄带干扰和低频磁场耦合信号的影响；不存在定位盲区；具有足够的脉冲分辨率；所采用的频带较窄，相应的传感器较易制作。
