Calcium carbonate and soluble glass and so on were confected as alkaline antifouling agent. The Infrared Spectrometry results showed that 2275-2250 cm~(-1) diagnostic absorb wave crest in part A and 3390-3200 cm~(-1) in part B and 1730 cm~(-1) in coating film strongly proved polymers reacted just as the reacting mechanism, that means polysiloxane which offer low-surface-energy property linked Polyurethane system by —OH groups reacting with —NCO groups. Relative molar mass of part A and part B was determined by Gel Permeation Chromatography and the results were appropriate. Surface-energy was determined and results were between 33.6-47.17 mN/m and it increased when alkaline antifouling agent was put into the coating. Alkaline antifouling agent was releasing steadily when the coating film was dipped in seawater. As time gone, the pH value of seawater was increasing. Solubility parameter and results showed that there was no corrasive phenomenon between the polyethylene strand and the coating.

As a result, the DNA segment of predicted size, about 372 bp, appeared in the two kinds of vibrio, but didn't appear in the others. Therefore, a rapid detection kit for V. alginolyticus was developed successfully. It could provide a quick, exact diagnosis and detection method for the diseases in aquatic animals and human beings, and also for the aquatic food security caused by V.alginolyticus. 3. Furthermore, this detection kit was used to investigate the distribution of V.alginolyticus in seawater of living area, healthy aquicultural seawater ...
此外,我们利用此试剂盒对海南地区的生活区附近海水、水产动物养殖健康区海水和发病区海水进行了溶藻弧菌存在情况的调查,结果显示,生活区附近海水的溶藻弧菌数明显低于水产动物养殖健康区海水和发病区海水,后两者中又以发病区海水的溶藻弧菌数量最多;无论是在水产动物养殖健康区还是在水产动物养殖发病区,养殖场的进水处海水中溶藻弧菌的数量也明显低于养殖池水中的数量。
