在股份制具体形式的选择上，通过对两类股份制公司形式的比较，论证股份有限公司制是国有商业银行股份制改革的最佳模式，并认为在组织形式上应由总分行制改为集团公司制；在产权结构上，探讨了只有建立现代商业银行制度，才能真正实现国有商业银行的产权清晰、权责明确、政企分开、管理科学；在公司治理模式上，强调建立真正的法人治理结构，较为详细地介绍了国有商业银行的股东大会、董事会、监事会等组织结构框架及作用；最后探讨了国有商业银行股份制改革需要注意的几个问题及风险防范。

The direct incorporation of U-13C glucose was estimated by the intensity increase of m/z to F(F was parent fragment, and n was the carbon number in the fragment), while the total isotope incorporation from the added 13C could be calculated according to the abundance ratio increment summation from m/z (Fa+1) through (Fa was the fragment containing all original skeleton carbons, and T was the carbon number in the amino acid molecule). The 13C enrichment in the target compound was expressed as atom percentage excess, and that of D-amino acid needed to be corrected by the coefficient of hydrolysis-induced racemization. The 13C enrichment reflected the carbon turnover velocity of individual amino acid enantiomers, and was powerful to investigate the dynamics of soil amino acids.

外加葡萄糖直接合成氨基酸的比例可利用质谱碎片的相对强度变化来评价（n为质谱碎片F中含有的碳原子数目）；而源于葡萄糖的13C同位素在氨基酸分子中的富集程度是所有同位素峰相对强度变化的总和。13C在目标化合物中的富集比例用原子百分超评价，D氨－基酸的APE还需进一步利用水解诱导的外消旋化系数校正。13C在目标化合物中的富集程度可反映各氨基酸手性异构体的碳循环速率大小，是研究土壤氨基酸动态变化的有力工具。

The dolphin's behaviors inclde feeding, traveling and playing were mostly observed in Xigang, Jiyu, Qingyu, Wuyu water areas. The abundance ratio of behavior observed in Jiyu, Qingyu, Wuyu water areas were highest, it indicates that these areas are important to the ptotection of Chinese white dolphins inhabiting the Xiamen Bay.

摄食行为、旅行行为和游戏行为主要集中在厦门西港和鸡屿至青屿、浯屿一带水域内，尤以鸡屿至青屿、浯屿一带水域内的行为丰富度最大，说明该区域对厦门中华白海豚的保护至关重要。

The prevalence and abundance of the acanthocephalan exhibited very similar and significantly seasonal change patterns in O. uncirostris and H. bleekeri bleekeri. The infection levels were higher in autumn and winter, but lower in spring and summer. However, the infection levels in Z. platypus kept stable all the year round. There were significant differences among the overall abundance of the acanthocephalan in the three host populations. Nevertheless, the frequency distribution of the parasite in the three kinds of fish was over-dispersed in most seasons and in total as measured by the variance to mean ratio. The variance to mean ratio was not found related to the infection levels.
