This usually means a class library with a fundamental base class for defining a complete program.

应用程序架构通常指用于定义完善程序的一个带有基本基类的类库。

They share many similar or the same featutes with Archaeopteryx or other primitive birds, such as: U-shaped furcula, uncinate process, laterally facing glenoid of shoulder girdle, comparatively long forelimb, large semilunate carple, retroverted pubis, ascending process of astragalus, and "modern feathers"with rachis and barbs etc.

奔龙类是一类较为特殊的手盗龙类，它具有许多与始祖鸟Archaeopteryx甚至其它早期鸟类相似或接近的特征，主要表现在：叉骨U形与始祖鸟和孔子鸟类的相同，背肋钩状突在孔子鸟类和个别反鸟类中也存在，肩臼窝绝大部分指向侧方类似于始祖鸟，肩胛骨与乌喙骨间的夹角非常接近90°也和始祖鸟的相似，前肢从比例上讲显得较长，大的半月形腕骨使肘部能向侧方折过来，耻骨伸向后下方，距骨上升突与原始鸟类中的为同源结构，羽毛已有显著的分化且具备了现代羽毛的基本结构等等。

For the timelike surfaces with constant positive Gaussian curvature (K=1) in R〓, we construct the correspondence between R〓 and sl (2, R), and deduce the fundamental equations for a special choice of the velocity of motion of time-like surfaces in asymptotic coordinates under suitable conditions, meanwhile, we give the B〓cklund transformation and one soliton solution of the evolution equations, then in terms of a gauge transformation we obtain the explict expression of the motion of surfaces.

对于三维Minkowski空间R〓中具有正常高斯曲率（K=1）的类时曲面，取定特定速度，在以渐近线作为坐标曲线的情况下，曲面运动满足两个基本方程，即sinh-Gordon方程和θ随时间演化的方程（其中θ表示两条渐近线之间的夹角），同时给出两个基本方程的B〓cklund变换和单孤子解，并通过规范变换给出相应的正常高斯曲率曲面的显式表达式。

It focuses on examining the subjects' abilities to find tonality and mode, perceive tendency of melodic pitches and harmonic functional progression, and recognize meter and segment the groups of rhythm. We can thus consider whether or not receiving harmonic training has an influence on recognizing meter and segment groups of rhythm.

它包含调式调性的确定、旋律音高的倾向、和声的功能解决、拍号的识别以及节奏组合的划分等测验项目，实验结果表明，师范类音乐专业大学生对调性音乐音高层面基本组合规则的感知能力不存在统计意义上的差异；是否学过和声对个体把握音乐在时间层面的基本组合规则具有影响作用。

The method does not need any special instruments and is more convenient than the methods that we have mentioned. It is an efficient means for rapid diagnosis. In addition, mutiple-clone rabbit IgG is made by the lipoid A of E. coli.

另外，多克隆兔抗大肠杆菌抗体IgG由大肠杆菌的类脂A制成，具有广谱免疫原性，肠杆菌科细菌的类脂A结构基本相同，可进行交叉免疫反应。

By the definition of Green-relation and the analogue of generalized Greens lemma, this paper first studied some properties of H-class、 D--class of rpp semigroups, then by left S-system 、-bisystem and tensor product, we described a blocked Rees matrix semigroup. Especially, the paper studied primitive rpp semigroups .

本文利用在rpp半群上定义的广义Green~(l-关系及相应的广义Green定理，首先研究了rpp半群H~(l-类、D~(l-类的若干基本性质，然后以左S-系、-双系和张量积作为工具，刻画了块Rees矩阵半群结构，最后从带零的本原rpp半群出发，构造出A型块Rees矩阵半群，并证明了一个半群S为本原rpp半群，当且仅当S同构于一个A型块Rees矩阵半群。

In the method,based on the traditional ideas of maximal tree clustering method,the dyadic semantic representation is used to process the linguistic assessment information,and the clustering objects are classified.

该方法依据传统的最大树聚类分析方法的基本思想，采用二元语义概念对语言评价信息进行处理和运算，并对聚类对象进行分类，具有概念清晰、计算简单、信息处理较为精确的特点。

Then, the first and second fundamental forms, Gaussian curvature and mean curvature of the surfaces are directly calculated according to the principles of differential geometry.

首先，根据微分几何中的基本知识，得到了该种度量形式下的平移曲面的第一、第二基本形式以及高斯曲率和平均曲率；然后，主要利用高斯曲率和平均曲率之间的线性关系和平方关系，得到了这类平移曲面的分类定理。

Since designers, manufacturers, and quality inspectors in the industrial sector all have to rely on the common language, mechanical drawing, to communicate or convey messages among one another, Mechanical Drawing Practice has always been a not only important but also required course in the industrial vocational high school curriculum.

机械图是工业界的共同语言，不论是设计者、制造者或检验品管等相关人员都必须赖以作为彼此间沟通或传递讯息的依据﹔因此，高工机械群之中除制图科将机械制图与实习列为专业必修科目外，在其他各科的课程标准中机械制图与实习课程亦为必修科目﹔而课程中基本制图部分单元更是工业类个群专业必修的基础科目，由此可知，举凡与制图有关之机械制图、工程图学等课程在高职工业类科的课程中所占有的重要性。
