The results of three cladistic methods showed: the consanguinities of different genera in a same tribe were closer, such as Chalcis and Conura, Trigonurella, Megalocolus and Trigonura; the consanguinities of genera between different tribes were farther, such as Chalcis and Brachymeria, Dirhinus and Hallichella; Chalcis, Conura, Brachymeria and Epitranus were the most primitive relatively, Tainaniella and Oxycoryphe were the most evolutional, the consanguinities were the farthest between the former and the latter; the genera with the closest consanguinities were: Tainaniella and Oxycoryphe, Proconura and Nipponochalcidia, Chalcis and Conura, Megalocolus and Trigonura, they were regarded as 4 pairs of sister groups.

三种支序分析方法一致支持的结果为：同一族内成员之间亲缘关系较近，如小蜂属和卡诺小蜂属，微三角小蜂属、细尾小蜂属和三角小蜂属之间；不同族内成员相互之间的亲缘关系则较远，如小蜂属和大腿小蜂属之间，角头小蜂属和截胫小蜂属之间；小蜂属、卡诺小蜂属、大腿小蜂属和脊柄小蜂属相对最为原始，而泰内小蜂属和背突小蜂属最为进化，前者和后者之间的亲缘关系最远；亲缘关系最近的有：泰内小蜂属和背突小蜂属，泊卡小蜂属和日本小蜂属，小蜂属和卡诺小蜂属以及细尾小蜂属和三角小蜂属，它们各自之间都构成姊妹群关系。

To improve the efficiency of Oxalis triangularis purpurea breeding, this study is done by leaf explant. 0.5 mg/L 6-BA and 0.5 mg/L NAA are added to the culture based on the last study. KT and 2,4-D concentrations impact on Oxalis triangularis purpurea regeneration system by "one-step method" are further studied.

为提高三角紫叶酢浆草的育苗效率，以三角紫叶酢浆草叶片为材料，在现有研究的基础上，采用固定配比的6-BA(0.5mg/L)和NAA(0.5mg/L)，研究了KT、2，4-D对"一步法"诱导三角紫叶酢浆草再生体系的影响。

As part of the contents of this triangle involving more to the formula, with a corresponding change it, in solving problems, how to destinations such as triangular constant transformation trigonometric function is the key to learning paper presents some problems to resolve Trigonometric function methods and techniques, hope to play a role.

由于三角这部分内容所涉及到的公式比较多，相应地变化也就多，在解题中，如何有目的地进行三角恒等变换是学好三角函数的关键。本文介绍一些解决三角问题的方法和技巧，希望能起到抛砖引玉的作用。关键词三角函数；方法；技巧

Every harbour is small but combination in administrative divisions inner formation since the rim of Bohai Bay does not realize the long similar triangle , limpid-rization , leading to ring the Bohai Sea harbour resource duplication of similar projects and contending for source of goods , the nothing order racing to control hinderland competing neither samer than long triangle harbour group "an integral whole both wings " develops power state's is especially more fierce than growing a triangle.

但是由于环渤海地区还没有实现类似长三角各港口在行政区划内形成的小组合，也不同于长三角港口群&一体两翼&发展势态的清晰化，导致环渤海港口资源重复建设和争夺货源、抢占腹地的无序竞争比长三角更加激烈。

Orientation field near core point is changeable which is influenced by core point. Then fingerprint orientation field outspreads. At last, orientation field converges at delta point. This model can explain well why core and delta points exist in pairs in fingerprint images.

基线区域和中心点区域的指纹方向场向外扩张，在三角点区域汇合，且三角点是最终的汇合点，这一模型能比较好地解释指纹中心点和三角点成对出现的原因。

Orientation field near baseline is parallel to baseline which is caused by baseline. Orientation field near core point is changeable which is influenced by core point. Then fingerprint orientation field outspreads.

基线区域和中心点区域的指纹方向场向外扩张，在三角点区域汇合，且三角点是最终的汇合点，这一模型能比较好地解释指纹中心点和三角点成对出现的原因。

The triangulating algorithm for discrete surface is presented.

在空间离散点曲面的三角划分方面，提出了限定相邻三角片的法线夹角的空间离散点曲面三角网格划分方法。

Painted mostly in black, use either brown-red; decoration in order to change patterns of plant leaf tissue the main triangle dots are curved, half-moon, geometric shape such as decoration, while the pattern is often curved triangular structure 22 opposite or contrary to , side-side, middle, or draw a straight line or without pattern, with a few arc composed of upper and lower triangular or half moon or the top of the left commensurate with quite a few patterns, followed by a small amount of a pattern of squares, bands and so on.

彩绘以黑色居多，兼用棕红色；纹饰以植物叶纹变体组织为主，有弧形三角圆点、半月形、几何形等纹饰，而图案的结构往往是弧形三角两两相向或相背，侧旁、中间或绘直线或无纹，以几个弧形三角或半月形组成的上下左右相称或对顶的纹样也不少，其次还有少量的方格纹、带纹等。

面临旅游市场进一步开放带来的压力，在长三角打造区域无障碍旅游圈的发展目标体系下，如何更好地发展长三角区域旅游产业、更好地协调长三角区域旅游发展，这些问题成为当前许多学者、企业家等共同探索的焦点。

In partial celestial sphere celestial Star-Identification, the initial attitude is known. With a certain angular and distance tolerance, the separation angle of the observed stars and that of the catalog stars are matched, then, the star triangles are composed in real time. According to the rules of vector rotation, the inconsistent rotation star triangles are removed. After that, put the star triangles with public vertex into star polygon.

在局部天球星图识别方面，因为已知初始姿态，在一定角距容差和星对容差范围内和已知视轴附近的导航星角距表进行角距匹配，实时组成星三角，根据矢量法则剔除旋转方向不一致的星三角后，再把拥有公共顶点的星三角组合成星多边形。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。
