The results manifest that the concentration of glycocholic acid has satisfactory linear correlation whith peak area, regression equation: Y= 39579X + 57823,R2=0.9984;The lowest detected concentration is 0.02μg/mL with S/N=3 ; Average recovery rate is 98.49%; RSD为0.52%～2.00%in day, RSD为0.74%～4.98%between days;The average recovery rate is 99.35%, RSD is 2.24% in the first team, and it is 100.87%, RSD is 4.73% in the second team at the stability test. When the concentration of glycocholic acid was detected in the liver, kidney and brain tissue, corresponding tissue concentration was calculated by preparing the standard curve with the glycocholic acid standard preparation in vitro, but the result can only reflect the relative chang law of the concentration of glycocholic acid in tissue but not in real tissue. The result of tissue stability experiment is consistent with that of the serum experiment.

After reading and integrating lots of correlative science and technology books, the domestic and international research on CRM is summarized, and then the system frame is built. The conception of relative degree is proposed in the theory, which involves some methods in economics, such as the lifecycle curve of product or technology and the principle of time sequence, and so on. So the foundation for researching the system is built. Applying the technology of data warehouse and the correlative arithmetic of data excavating and method for classifying the clients, the resource analysis module is built,and the problem of data disposing and service management is resolved. The clear relationship of clients and sale strategy is obtained and the valuable client resource is grubbed up by analyzing the information of the clients. The enterprises will gain more clients and businesses opportunity, accordingly, the effect of less investment and more output.is attained.
