利率市场化的风险分析

中国有关部门宣布中国将在今后三年逐步实行利率市场化 ,可以说这是一个顺应金融自由化时代潮流作出的明智的选择。本文分析了中国在推行利率市场化过程中可能会存在的几种风险 :利率市场化会加剧逆向选择 ;利率市场化可能会抑制物价回升、抑制投资 ;利率市场化可能会形成垄断性利率 ,造成无序竞争 ;利率市场化给国有商业银行利率制定带来的问题并进而提出了防范风险的认识和办法

分析了南海北部神狐海域含天然气水合物沉积层声波速度及密度的分布特征和变化规律,并通过对比dSdP 84航次570号钻孔含天然气水合物层段测井资料,总结出神狐海域含水合物地层的测井响应规律特征:神狐海域含水合物地层存在着明显的高声波速度、低密度特征,地层密度随声波速度的变化并不是单一的反比例关系,总体趋势上随声波速度的升高而降低;含水合物地层高声波速度值主要集中在197--220 M段,饱和度值在15%--47%之间,低密度值集中在200--212 M段,分布在水合物饱和度大于20%的地层内;含水合物地层声波速度平均值为2 076 M/S,其上覆和下伏地层的声波速度平均值为1 903 M/S和1 892 M/S,所对应的地层密度值分别为1.89 g/CM3、1.98 g/CM3和2.03 g/CM3,声波速度受孔隙度和饱和度的共同影响,地层密度受水合物饱和度影响较大;从水合物上覆地层到声波速度最高值段,声波速度值增加了9.1%,相对应的地层密度值减少了4.55%,从水合物声波速度最高值段到下伏地层,声波速度值减少了8.86%,相对应的地层密度值增加了7.41%。这些测井响应特征,可用来识别地层中天然气水合物,并可以用来计算水合物的饱和度,同时结合其他地质和地球物理资料,确定水合物层的厚度、分布范围,计算天然气水合物的资源量。With analysis of the distributing feature and the changing law of the sonic velocity and density of sediments with gas hydrate in Shenhu Area of the South China Sea,by comparing with logging data of gas hydrate formation at Site 570 of DSDP 84,the logging response characteristics of gas hydrate formation in Shenhu Area were conducted.The results show that:(1)Sediments with gas hydrate in Shenhu Area have the clear features that the sonic velocity is high and density is low,and the density is generally decreased with the increasing of the sonic velocity.(2)The high sonic velocity section in sediments with gas hydrate is in the depth of 197 to 220 m,and the low density section is in the depth of 200 to 212 m;the value of saturation is in the range of 15%to 47%.(3)The average sonic velocities of sediments with gas hydrates and the overlying strata and underlying strata are 2,076 m/s,1,903 m/s and 1,892 m/s,respectively,and the corresponding densities are 1.89 g/cm3,1.98 g/cm3 and 2.03 g/cm3,respectively;sonic velocity is effected by porosity and saturation,and density is greatly influenced by saturation;(4) The sonic velocity increases by 9.1% from the overlying strata of hydrates to the maximum-value section,and the corresponding density decreased by 4.55%;the sonic velocity decreases by 8.86% from the maximum-value section to the underlying strata of hydrates,and the corresponding density increases by 7.41%.The logging response characteristics can be used to identify the existence of gas hydrates and to calculate the saturation of gas hydrate,furthermore,to provide accurate area and thickness of gas hydrate zone for calculating gas hydrates reserves with combination of other geological and geophysical data.中国科学院边缘海地质重点实验室项目(MSGL08-03);国家重点基础研究发展计划(2009CB219508

A STUDY ON THE INNOYATION OF THE PROPERTY RIGHTS SYSTEM OF THE STATE-OWNED COMMERCIAL BANKS IN CHINA

本论文研究的是我国国有商业银行产权制度创新问题。论文首先简要述评了产权和产权制度的有关内容，并以此作为本论文分析的理论基础。 论文接下来研究了国有独资商业银行产权制度创新的必要性。首先，文章从实证的角度对不同产权制度安排下银行的绩效进行比较，主要包括两个方面的比较：一个是比较中国银行和外国银行的不同绩效；另一个是比较国有独资商业银行和股份制商业银行的不同绩效。得出结论：国有产权制度安排是一种低效的制度安排，它的外部性比较大，因此有必要对其进行创新；其次，从规范的角度分析了国有独资产权制度创新的必要性。主要分析了在国有产权制度安排下政府与行长、行长与企业经理、上级行长与下级行长这三种基本的委托...This paper focuses on the study of the innovation of the state-owned commercial banks’ property rights systems in China.

COMPARATIVE STUDIES ON THE TOTAL PIGMENT AND PIGMENT COMPONENTS OF COLOR CARP

用光谱和色谱两种方法对锦鲤的总色素和色素组分进行了研究。研究结果表明,红色锦鲤、乌鲤和绯写锦鲤总色素光谱在可见光区(448nm和470nm)有两个完全相同的吸收峰,黄写锦鲤和昭和三色锦鲤总色素光谱在可见光区(445nm和472nm附近)有两个相近的吸收峰,锦鲤所含色素组分均以杏黄色或橙色为主,其他色素组分为辅。锦鲤黑色色斑是由于黑色素存在时,其他各色素组分的颜色被黑色所掩盖;锦鲤其他色斑的形成则是由于其体内各色素组分以不同比例相互搭配组合的结果。亲缘关系越近的锦鲤其总色素组分就越相似,红色锦鲤和乌鲤均含有六种相同的色素组分,绯写锦鲤除杏黄色和橙色色素组分与前二者的同色色素组分Rf值不同外,其余四种同色色素组分的Rf值均相近;黄写锦鲤与昭和三色锦鲤分别含有三种和四种色素组分且Rf值差异显著。据此推测,红色锦鲤、乌鲤和绯写锦鲤可能具有较近的亲缘关系,而黄写锦鲤、昭和三色锦鲤与前三者之间可能具有较远的亲缘关系。该研究有望为锦鲤增色饵料的研制与开发提供理论依据,使锦鲤的观赏价值和经济价值得到进一步提高。The study was conducted to investigate the total pigment and pigment components of different breeds of color carp by spectrophotometer and thin-layer chromatography.The results showed that spectrum of total pigment of Red Color Carp and Black color Carp and Black Spot-Red color Carp had two same absorption peaks in visible lregion(470nm and 448nm).The spectrum of total pigment of Black Spot-Yellow color Carp and Black-Blue-Red Spot-color Carp had two similar absorption peaks in visible region(445nm and 472nm).The pigment components of different breeds of brocaded carp were mainly apricot or orange pigment.The black spots of color carp may be formed when melanin covered other pigment,other color spots may be formed when the pigment components of all kinds were mixed in proper proportions.The more the relation of color carp is close,the more the total pigment component is similar.Red color Carp and Black color Carp had same pigment components of six kinds,there were similar Rf values of four same color pigment components for Black Spot-Red color Carp as compared with both of the former and there were different Rf values of two same color pigment components for the latter in comparison with both of the former.Black Spot-Yellow color Carp and Black-Blue-Red Spot-color Carp had three and four pigment components respectively,and the difference of their Rf values was notable.As above,Red color Carp and Black color Carp and Black Spot-Red color Carp probably are close relatives,and the former and Black Spot-Yellow color Carp of Black-Blue-Red Spot-color Carp probably are distant relatives.This study will help the research and development of color carp color-adding diet and further enhancement of brocaded carp ornamental value and market value.广东省科技计划项目(2002C20304);; 广州市科技攻关重点项目(2002Z2-E0102)资

COMPARATIVE STUDIES ON THE TOTAL PIGMENT AND PIGMENT COMPONENTS OF GOLDFISH

用色谱和光谱两种方法对金鱼总色素和色素组分进行了研究。研究结果表明,红鲫、草金鱼和红龙睛等红色金鱼总色素光谱在可见光区(472nm附近)有一个吸收峰,黑鲫和黑龙睛等黑色金鱼在可见光区(450nm和472nm附近)有两个吸收峰出现,且红色金鱼所含色素组分以红色(虾青素)为主,黑色金鱼所含色素组分以杏黄色和橙色为主,其他色素组分为辅。金鱼黑色色斑形成是由于黑色素存在时,其他各色素组分的颜色被掩盖的结果;金鱼其他各种色斑的形成则是由于其体内各色素组分以不同比例相互搭配组合的结果。亲缘关系越近的金鱼其总色素组成就越相似,红鲫和黑鲫均含有四种近乎相同的色素组分,红龙睛和黑龙睛均含有六种近乎相同的色素组分,草金鱼虽也含有四种与红鲫和黑鲫相近的色素组分,但Rf值略有差异。据此推测,红鲫和黑鲫、红龙睛和黑龙睛可能分别具有较近的亲缘关系,而草金鱼则可能是介于黑鲫和龙睛鱼之间,且与黑鲫具有较近的亲缘关系。该研究有望为金鱼增色饵料的研制与开发提供理论依据,使金鱼的观赏价值和经济价值得到进一步提高。The study was conducted to investigate the total pigment components of different breeds of goldfish by spectrophotometer and thin-layer chromatography.The results showed the spectrum of total pigment of Red color crucian.Grass goldfish and Red Dragon-eye had one absorption peaks in visible region(472nm). The spectrum of total pigment of Black carp and Black Dragon-eye had two similar absorption peaks in visible region(450nm and 472nm).The pigment components of different breeds of Red color goldfish were mainly Red pigment(astaxanthin). The pigment components of different breeds of Black color goldfish were mainly apricot or orange pigment.The black spots of goldfish may be formed when melanin covered other pigment,other color spots may be formed when the pigment component of all kinds were mixed in proper proportions.The more the relation of color spots is close,the more the total pigment component is similar.Red color crucian and Black carp had same pigment components of four kinds,Red Dragon-eye and Black Dragon-eye had the same pigment components of six kinds,although there are four pigment components,which are close to the ones in Red color crucian and Black carp in the body of Grass goldfish,but Grass goldfish's RF has slight difference with Red color crucian and Black carp.As above,Red color crucian and Black carp,Red Dragon-eye and Black Dragon-eye probably are close relatives,respectively,and the category of Grass goldfish may possibly fall between Black carp and Dragon-eye,which has a closer relative with Black carp.This study will give help to the research and development of goldfish color-adding diet and further enhancement of goldfish ornamental value and market value
