In the conformation change process, the second hyperpolarizability values of system and for singlet are negative system (a of 45° and 135° with the exception, and less than the absolute value of all triplets. The second hyperpolarizability values of system for singlet and triplet states are positive and in molecular close plane configuration time, the value of triplet is greater than that of the singlet.

在构象变化过程中，体系和单重态的二阶超极化率均为负值体系(a的45°和135°除外，且绝对值都小于三重态的二阶超极化率值，体系的单三重态二阶超极化率值均为正值，且在分子接近平面构型时，三重态的γ值大于单重态。

Tricholoma may be a paraphyletic genus two. The collections identified as T. caligatum is a mixture. Some parts of them from France are members of T. matsutake, the other parts from North America are closed to T. bakamatsutake and T. fulvocastaneum. Tricholoma robustum and T. focale form a clade which is obviously a sister group of the stirp Subannulate. The stirp Caligata was defined as a group mainly on the basis of the predominant veil. But from the result of molecular systematic analysis, the presence of veil is not a stable character in the matsutake group. Species having symbiosis with conifers and broad leaf tree are all transformed from those whose host specificity is not strict. The phylogenetic tree based on ITS sequences resembled the tree of NJ algorithm based on cladistic coding. In the phylogenetic tree based on morphylogical characters, T. zangii and T. bakamatsutake form a clade, but it is the result of convergent evolution as suggested by molecular analyses. The distribution area of the matsutake group can be divided into six regions: middle and northern Europe region, Mediterranean region, Hengduan Mount.— Southeastern Tibet region, Northeastern China—Japan—Far-east Russia region, the Atlantic—North America region and the Rocky Mountain region. The abundance center of the matsutake group are Hengduan Mount.—Southeastern Tibet region and the Rocky Mountain region. Hengduan Mount.

松口蘑群的分子系统学研究得出的结果有：由于粗壮口蘑和羽衣口蘑明显和亚环族(Tricholoma，section subannulate)的种类是来自同一个谱系，和其它松口蘑群的种不具有最近共同祖先，因此松口蘑群是一个多系群；松口蘑群和口蘑属其他种类的亲缘关系比和蜜环菌属更接近；梭柄松苞菇和松口蘑群的差距明显小于油黄口蘑(T.flavovirens)和棕灰口蘑；口蘑属是一个多系群；鉴定为欧洲口蘑的标本明显不是一个单系群，其中一部分是松口蘑，另一部分和黄褐口蘑及傻松口蘑(T.bakamatsutake)比较接近；划分松口蘑群的标准是菌环的存在，但从分子系统学的结果来看，菌环的存在与否并非是一个很稳定的性状；和针叶树专性共生及和阔叶树专性共生均由寄主专化性不强的种类转化而来；在形态学系统发育树上青冈口蘑和傻松口蘑被聚为一个分枝，分子系统学的研究结果表明，这是趋同进化的结果；用支序方法编码作出的NJ树的结果更接近ITS序列的结果。

Our study to I-V curve of thiophene shows that its transport capacity is stronger than that of single benzene.

It is expected that hyg would be integrated stablely into the chromosome along with insert while spc/str would be lost during the second cross-over. Gene replacement through these two flanking sequences will result in the susceptibility of the transformants to phage φHAU3, which provides an enrichment for desired transformants by counterselection.

预期在携带有大插入片段的基因置换YAC分子进入野生型变铅青链霉菌后，YAC分子将通过1.4kb或1.0kb片段与染色体发生同源单交换，继而发生同源双交换，hyg连同大插入片段一起稳定地整合到染色体上，而spc／str丢失，从而导致菌株Hyg〓Str〓的表型。

Methods］The application of AFLP in severalpathogens(such as Legionella pneumophila, Flavobacterium, Aeromonas, Clostridium,Bacillus, Acinetobacter, Pseudomonas, Vibrio, Helicobacter pylori and Group AStreptococcal)was reviewed and especially compared with other molecular epidemiologicalmethods.［Results］AFLP shares many characteristics with other genomic fingerprintingmethods.

方法］对近年来AFLP技术在几种病原菌（嗜肺军团菌、黄杆菌属、气单胞菌属、梭状杆菌属、芽胞杆菌属、不动杆菌属、假单胞菌属、弧菌属、幽门螺杆菌和A组链球菌）的应用进行综述，并与其它分子流行病学方法进行比较。

Using Parantica aglea and Euploea core as the outgroups, the phylogenetic trees of the Nymphalidae taxa in this study were reconstructed with and Bayesian methods based on 16S rDNA, 12S rDNA and their combined sequences. The results showed that the Nymphalinae was not monophyletic; the Junonia should be classified into Hypolimni; the Apaturinae, Byblinae and Nymphalinae were closely related to each other; the Pseudergolinae and Byblinae should be separated from Limenitinae.
