Results On day 7, 15, 30 after injection with exogenous VEGF, the mice in VEGF group were found more renascent blood vessels, splenic corpuscles, central arteries and peripheral lymphatic sheathes in the autotransplanted splenic tissues than the control group, and eventually formed more integral structure of white pulp, marginal zone and red pulp with much less fibrous tissue, while on day 60 there was no significant difference between VEGF group and the control group.

In the empirical analysis part, statistical descriptions on the sample funds are made firstly, which show that the actual distribution of each sample fund"s daily net value return possesses the characteristic of leptokurtosis. So it is necessary to add student T distribution and GED to capture such leptokurtosis characteristic other than normal distribution. Secondly, ARCH test shows that there exists volatility clustering in each sample fund"s daily net value return, so GARCH related models should be used to describe such volatility clustering characteristic.

实证分析部分首先对样本基金进行统计描述,得出其收益序列均存在尖峰厚尾特征,不服从正态分布,因此有必要在下面的VaR计算中加入T分布和GED分布来捕捉这种尖峰厚尾特征;并且经ARCH检验后得出收益序列存在明显的波动聚集性的特征,因此可以选择GARCH类模型来描述这种特性,经过模型筛选,得出最适合我国开放式股票型基金的收益波动性模型为GARCH(1,1)模型。

Based on the classical Ekman theory, a series of intermediate Ekman boundary layer models, which retain the nonlinear advective process while discard embellishments, have been developed with the intention to understand the complex nonlinear features of the Ekman boundary layer and its interaction with the free atmosphere. In this paper, the recent advances in the intermediate boundary-layer theoretical models are reviewed.

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。

Firstly,we particularly explained the algorithmic of themusic recognition.Then,we made a study of the music characteristic and the musicrecognition methods.As for the burrs of the music signal,we put forward a curveplastic method to eliminate the burrs.Considering the difficulties of detecting thepoint of the music speech,we made use of the multi-frequency energy curve to detectthe end-point of the music signal with the crossing zeros rate.As for thedisadvantages of the large operation and influence of the formant,we improved theAMDF theory with the linear prediction algorithmic to detect the error.In order toobtain the characteristic parameter of the music signal,wo calculate the MFCCparameter to obtain the template and the pending signal characteristic parameter.Inorder to improve the rate of the recognition,considering the disadvantages of theDTW algorithmic,we find a new method to improved the DTW algorithmic bybroadening the point of the music signal and made simulation experimentation;As forthe disadvantages of the contraposition grade to the pitch,cadent and sing name,wefind a method to dynaic adjust the results of the recognition to improve the accuracyof the grade.

The results of study show:1. White pulp and red pulp in parenchyma of spleen of embryo can be obviously discerned after 18 days. Periarterial lymphoid sheath and ellipsoid periarterial lymphoid sheath also can be obviously discerned in spleen of 4 days chicken. T, B lymphocytes in appendix basement of embryo emerge after 20 days. It is the initial shape of cecal tonsil. Crypt structure of conjunction of esophago and stomachus glandularis form obviously at 4 days. It is the initial shape of esophago tonsil. The germinal center firstly emerges in these three organs at 14 days. With the increase of day age, the characteristic structure peripheral immune organs gradually develop mature. Spleen achieve mature at 21 days and cecal tonsil at 35 days.2. IgM~+ and IgA~+ cells in spleen of embryo emerge at 15 days. IgG~+ cell, CD3~+ and CD8~+T lymphocytes of embryo emerge at 20 days. CD3~+, CD8~+ and IgM~+ cells in cecal tonsil of embryo emerge at 20 days. However CD4~+, IgG~+ and IgA~+ cells all emerge in 1 day age chicken out of crust. CD3~+, CD4~+, CD8~+, IgM~+ and IgG~+ cells in esophago tonsil of embryo all emerge at 20 days. However IgA~+ cells emerge in 1 day age chicken out of crust.3. The amount of T, B lymphocytes in peripheral immune organs increase follow with the increase of day age, and hold an upgrade tendency. The amount of T, B lymphocytes in spleen achieved stabilization at 21 days, and in tonsil of esophago and appendix at 35 days.
