Results 86.8% of IDUs could not insist on using condoms, 25.7% had multiple sexual partners, 49.0% had IDUs as sexual partners, 70.7% didn't know whether comate had infected HIV. High-risk sexual behavior was relative with these factors: starting drug taking at younger age, more frequencies of excessive injection, denial attitude to condom using, and using dirty injection equipment with others. Unmarried status, willingness to use condoms and voluntary HIV testing related with secure sexual behaviors.

结果 IDUs中86.8%不能坚持使用安全套，25.7%有多个性伙伴，49.0%有IDUs性伙伴，70.7%不了解对方HIV感染情况；首次吸毒年龄小、注射过量次数多、对安全套的否定态度、共用不洁注射工具与不安全性行为有关，而未婚、继续使用安全套意愿、自愿HIV检测等与安全性行为有关。

Although the nutritional content of genetically modified foods have no different from the ordinary, but because of its growth has been genetically modified by the biotechnology, the European Union people has suspected the comestible safety and environmental safety of the genetically modified foods and they have refused the food access to their markets.

Modular design is a common approach for dealing with complex tasks in modern cryptology; in which the main problem is that the secure sub-protocols no longer remain their security in the hybrid protocol. Canetti presents universally composable security framework for designing secure hybrid protocol.

协议模块化设计是协议设计领域的重要研究方向，其中最大的困难是子协议的安全性并不能保证组合协议的安全性。

How to assure and enhance the security of database, the core of datas storage and management in management information system, has been hot topic which is expected to be solved urgently.

作为信息化的关键——数据库，其重要性也是越来越高，然而由于军队信息化建设才刚刚起步，在很多地方由于数据的安全性和可信度的问题制约了发展的速度，甚至严重影响了信息化战斗力的提高；这就迫切要求在数据库的安全性和可信度上给予决策者以最大的支持。

Three batches of bivalent inactivated oil adjuvant vaccine to avian infectious coryza were produced and the safety and efficacy of them were also evaluated in this study.15 chickens were injected intramuscularly with 4-5 mL vaccine,there was no significant sign to be observed,and no lesions on the injecting spot after 2 weeks.

应用3批鸡传染性鼻炎二价油乳剂灭活疫苗进行了安全性和近期免疫效力检验，安全性试验采用15只鸡进行，胸肌注射疫苗4～5 mL/只后，逐日观察，结果鸡只食欲、精神未见异常，2周后观察，注射部位未发现明显异常和病变。
