The H-SPAM is used for the highly water absorption resin. Which is prepared by grafting acrylamide with starch under the catalyzing of initiator and the acting of cross linker. After hydrolysis we can get the products which is able to absorpte non-ionic water for hundreds times of its weight. But the water absorbency of the resin will be reduced due to the existance of ions. The higher the ion concentration is, the lower the water absorbency is. By using this resin, the solutes in solutions, such as protein,... The H-SPAM is used for the highly water absorption resin.

But the water absorbency of the resin will be reduced due to the existance of ions. The higher the ion concentration is, the lower the water absorbency is. By using this resin, the solutes in solutions, such as protein, enzyme and vitamin, can be concentrated. It also can be used for water treatment, medical treatment, and preservation of soil moisture. 本文采用的高吸水树脂为H-SPAM树脂。在引发剂、交联剂存在下,将丙烯酰胺接枝到淀粉上,然后水解得到吸收自重百倍的非离子水的产品。H-SPAM树脂在非离子水中吸水率较高,在离子(Na~+,Cl~-)水中吸水率较低,随离子浓度的增高,吸水率下降。这种树脂可用来浓缩蛋白质、酶制剂和维生素等大分子溶质,还可用于水处理、医疗以及水土保墒等。 Recent development of medical images such as application of new technology, image processing, type of medical films and the radioactive film emulsion technology are described. 本文介绍了近年来国外医用影像的发展状况、采用的新技术、影像处理、医疗诊断用胶片及医用胶片的乳剂制备技术。 According to the situation that the rate of medical disputes is rising in recent years, the concepts of medical disputes are correctly appreciated and their different causes studied. To cut down the disputes, the leadership should focus their attention to them. Technical training is due to be intensified, rules and operating regulations completed, and medical ethics strengthened according to the circumstances.

According to the situation that the rate of medical disputes is rising in recent years, the concepts of medical disputes are correctly appreciated and their different causes studied. To cut down the disputes, the leadership should focus their attention to them. Technical training is due to be intensified, rules and operating regulations completed, and medical ethics strengthened according to the circumstances. To handle the disputes fairly, complaints about medical failures should be given intensive care and preparations to handle the cases well made. Relevant laws should be studied to increase legal capacity. Volunteers should be contracted to do the social duty of overseeing and improving hospital services. 根据医院近年医疗纠纷发生率有上升趋势,正确认识医疗纠纷的概念,探讨了发生医疗纠纷的各种因素。在防范医疗纠纷上:①领导要高度重视;②加强技术训练;③建立健全各项规章制度和操作规程;④结合形势加强医德医风建设。正确处理医疗纠纷的态度:一是高度重视医疗工作方面的投诉和做好纠纷的接待处理工作;二是学习有关法律,提高依法办事能力;三是聘请义务监督员,发挥社会对医院工作的监督和促进作用。
