There are no distinct differences between ancestral character state and descendant character state in some characters. 4. Only one outgroup can't give enough information to tell what the ancestor looks like. It make us not to understand how a lot of charactors evolved. 5. The matsutake group is polyphyletic. 6. The character coding is not precise enough. 7. Some characters are not homology. The result of molecular systematic study on the matstuake group shows the group is not monophyletic. The matsutake group is more closed to Tricholoma than Armillaria. ITS sequence of Catathelasma ventricosum is nearly identical to that of the matsutake group, although apparently they are very different from each other in morphological characters.
对松口蘑群通过形态学特征进行系统发育关系分析造成很大的干扰的原因有:松口蘑的种类大多形态特征比较简单,可提供进行分析的特征不多;某些性状在一些状态之间的反复转化,造成分析上的误差;在进化过程中某些性状无明显的祖征和衍征,在分析过程中很难确定进化极性;选择外群时应该用一个特定类群进行整体理解后,确定各个性状的极性,不要只用单种作为外群;松口蘑群是一个多系群;进行比较的性状不一定是同源的;数量性状编码过于粗放,反映不出真实的情况。

On the basis of examination of more than 2000 specimens from 15 herbaria worldwide, the characters features of species,phonological phase,ecoloigical habit and the relation to close species were analyzed, recorded and described, the disputed species were compared, measured and counted in detail, the quantitative analysis to different characters was done through dot-map, the variation pattern of major morphology characters was analyzed and their significance for a better delimitation of the species was evaluated.

These concrete worksare the following:1, a new heterogonous SHS model had been proposed, which first included all the relativematerials characters, such as reactants particle sizes, changeable heat-conductivity and massdiffusion during SHS and so on, and its chemical reaction characters, initial combustion status.This new model made a more precise prediction about the SHS combustion way and itsTechnological characters possible.2, with the heterogonous SHS model, lots of combustion way had been imitated by changesystems relative factors and the rule of the combustion way change had also been studied,chemical reaction in these systems was controlled by a single mechanism.
在该模型中,首次将体系的微观不均匀特性、体系的基本物性及燃烧过程中的化学反应机理与整体燃烧动力学行为联系在一起,从而为更加准确地预测和控制SHS体系的燃烧行为,优化SHS的工艺过程奠定了理论基础。2、采用非均质燃烧模型,通过对相关参数的改变,模拟SHS燃烧过程中的各种燃烧行为,并研究了燃烧行为变化的规律。

In Chapter 2, starting from a generalization of Hensel's Lemma to non-commutative case, we introduce the Brauer characters and the generalized decomposition numbers, and construct a kind of maximal semisimple algebras; then, similarly to Puig's methods, we prove Brauer's Second Main Theorem over arbitrary fields; applying it to blocks with nilpotent coefficient extensions, a formula on characters of such blocks is given; the formula of characters of nilpotent blocks is just an easy consequence of the fomula.
在第二章中,我们将Hensel的引理推广到非交换的情况,以此为起点,定义了Brauer特征标和广义分解数,构造了一类极大的半单的代数,类似于Puig的方法,给出了任意域上Brauer的第二主要定理;作为该定理的应用,我们给出了具有幂零系数扩张的块的特征标公式,幂零块的特征标公式只是它的一个简单的推论。
