The research results show that the steam inlet pressure and water inlet temperature are the main factors which affect the lifting-pressure performance; the steam injector have the characteristics of self-adaptive outlet pressure and constant outlet flow rate; the theoretical maximum lifting-pressure coefficient calculated could be high as 14 and the experimental value is 3.0, which could be high as 1.5 even if the water inlet temperature is high as 95℃. The noise of steam injector could be induced from 80db to 50db.

The results showed: when TLC solvent system was: chloroform - methanol - diethyl amine = 90:9:1, alkaloids from lotus leaves were well isolated, and five components were isolated and identified by spraying Dragendorff reagent. The optimal conditions of HPLC solvent system were: methanol- water - diethyl amine = 75:25:0.0125. Under the conditions, components of alkaloids from lotus leaves were separated very well, and ideal RP-HPLC peaks were obtained.5、Methods of High Speed Counter Current Chromatography and preparative High Performance Liquid Chromatography applied to identify and purify alkaloids from lotus leaves were set up. When solvent system of HSCCC was: chloroform - methanol - water (pH=4.00)= 4:3:2, speed of chromatogram was 700rpm, flow speed of the mobile phase was 2mL/min, four pure components relatively were attained by isolation and purification.

Western blots were performed to investigate the cross-reactivity of various labeled antibodies with serum proteins from other fish species. Results Immunoglobulins of five fish species were purified, including bighead carp, carp, argus snakehead fish, ricefield eel, sea bass. The titers of five rabbit anti-sera obtained up to 1:32 examined by agarose double immunodiffusion. Five kinds of purified rabbit anti-fish immunoglobulins antibodies were labeled with HRP and their activities were up to 1:10000 examined by EUSA. Four kinds of rabbit anti-fish immunoglobulins antibodies labeled with HRP could react with serum proteins from other fish species.
