Through the design of AGP-test equipments and methods which could simulate the impact of input of exogenous nutrients on eutrophication, the evolution of algae and aquatic species extinction process in Miyun Reservoir under different environmental and nutritional conditions are simulated. Then the ratio growth rate in the three simulation stages are simulated and analyzed combining the numerical analysis software MATLAB 7.0. At last, the conclusion that in the three designed stage, the total phosphorus threshold which leads to a water bloom in Miyun is respctively 0.053mg/L, 0.062mg/L, 0.064 mg/L is educed. Based on the regression relationship of total phosphorus,chlorophyll-a, total nitrogen, and the transparency,we compartmentalized the evaluation standard level of eutrophication in Miyun Reservoir.

Objective:in order to compare the curative effects of using lamirudine and thymosin together with using thymosin only to the paients of chronic hepatitis b.methods:we had chosen 27 medical cases of chronic hepatitis b,which were divided into two groups:15 cases asone group,and 12 cases as the other group.let group a take 100 mglamirudine orally,qd,with half a year as a period of treatment.at the same time givethe patients injections of 100 mg thymosin,qd,for a month.to group b was only takenlamirudine.alt,tbil,the indicators of the virosis of hepatitis b (hbsag,hbeag,hbv-dna)were observed as quatos.results: at the end of the treatment, the rates that groupa and group b made hbsag transform into negative were respectively 26.67% and 16.67%(p＞0.05);hbeag:33.33%,8.33%;hbv-dna:53.33%,33.33%(p＞0.05).conclusion:combining thymic peptide with 3tc to treat chronic type b hepatitis, thymic peptide will not only promote b-cell to mature and transformation, but also to keep the subpopulation of t-cell in immune system in balance, which can enhance the reaction of matured t-cell to the antigen or other stimulus.

目的：比较拉米夫定（3tc）与胸腺肽联用和单用拉米夫定治疗慢性乙型肝炎的疗效。方法：选择慢性乙型肝炎患者27例，分为联合组15例和拉米夫定组12例；联合组用拉米夫定100 mg，口服，qd，疗程半年，合并用胸腺肽100 mg，静滴，qd，疗程1个月。拉米夫定组单用拉米夫定。以谷丙转氨酶、血清胆红素、乙肝病毒标志物(hbsag，hbeag，hbv-dna)为观察指标，比较不同治疗方案对指标的影响。结果：治疗结束时联合组与拉米夫定组对慢性乙肝患者血清hbsag阴转率分别是26.67％和16.67％(p＞0.05)；hbeag阴转率分别是33.33％和8.33％(p＞0.05)；hbv-dna阴转率分别是53.33％和33.33％(p＞0.05)。结论：胸腺肽联合3tc治疗慢乙肝，胸腺肽具有促进t淋巴细胞的成熟和转化，并维持免疫系统各t淋巴细胞亚群间的平衡作用，能增强成熟t淋巴细胞对抗原或其他刺激的反应。
