The evolutionary relationships were investgated by comparing the results from molecular data alone or molecular data combined morphological characters using different analysis methods: maximum parsimony by PAUP(superscript *) 4.0 and Bayesian inference by MrBayes 3.0B4. Base composition and ti/tv of 28S rDNA D2 regions were analyzed by PAUP(superscript *) 4.0. The results showed that GC content of the 28S rDNA D2 gene sequences of subfamily Euphorinae ranges from 40.00% to 49.25%. Transversion frequency of sequence variable sites among species of Euphorinae was higher than that of transition. The subfamily Euphorinae was proved to be a paraphyletic group with close relationship to subfamilies Neoneurinae and Cenocoelinae; only two tribes, Meterorini and Microctonini, were proved to be monophyletic groups; Centistini, Cosmophorini, Euphorini and Dinocampini were paraphyletic groups; the basal position of tribe Meterorini within Euphorinae was partially supported by our phylogenetic trees, and tribe Microctonini was proved to be a group at the top of the trees.

结果表明：优茧蜂亚科的28S rDNA D2基因序列片段的GC%含量在40.00%~49.25%之间变动，而对于碱基替代情况来讲，优茧蜂亚科各个成员间序列变异位点上颠换大于转换；不同的分析和算法所产生的系统发育树都表明目前根据形态定义出的优茧蜂亚科Euphorinae不是一个单系群，而是一个与蚁茧蜂亚科Neoneurinae和高腹茧蜂亚科Cenocoelinae混杂在一起的并系群；在优茧蜂亚科内部，悬茧蜂族Meterorini和食甲茧蜂族Microctonini（排除猎户茧蜂属Orionis）为单系群，而宽鞘茧蜂族Centistini、大颚茧蜂族Cosmophorini、优茧蜂族Euphorini、瓢虫茧蜂族Dinocampini为并系群；悬茧蜂族Meterorini在优茧蜂亚科Euphorinae内位于基部位置的观点得到部分的支持，同时食甲茧蜂族Microctonini被判定为相对进化的类群。

In [2], Kirkland characterizes the limit points for algebraic connectivity of trees in terms of Perron values of certain positive matrices, and finds the four largest elements of limit points for algebraic connectivity of trees together with the corresponding branches.

Kirkland在文献[2]中用正矩阵Perron值的方法刻划了树的代数连通度的极限点，并给出了树的代数连通度的前四大值和达到这些数值相应的分支。

Some researchers believe that the latter area possesses savanna vegetation. Savannas are closely associated with seasonal drought, and they may be defined by climatic climax vegetation in tropical and subtropical areas. Based on the ecoclimatic analyses as well as the surviving vegetation in Taiwan, we inferred that the potential natural vegetations of these 2 semi-arid regions were not savanna but forest with some drought-deciduous trees. In conclusion, the physiognomic type of grassland dotted with trees may occur in small areas at present, but Taiwan lacks climate-shaped savanna climax vegetation.

本研究将疏林定义为分布於热带及亚热带之气候形塑的极相植群，气候分析结果表明台湾半乾旱区域之缺水逆境并不严重，再配合现生残存植群之观察，发现台湾有形相为疏林的现生局部性植群，但其潜在自然植群应为参杂有乾旱落叶之阔叶树种的森林，并不存在较大面积之潜在的气候型极相疏林。
