By analysis of such models, a method, which is used to find out the region of convergence and to study the local stability for strong nonlinear system, are derived. Thus, we can consider the strong nonlinear neural networks using such method.

利用新的比较方法，考虑了具变时滞和常恢复率的同质人群HIV梯度传染病模型，得到了一个阈值，当阈值小于1时，疾病消除平衡点全局指数渐近稳定，当阈值大于1时，传染病平衡点存在唯一，同时得到该传染病平衡点局部指数渐近稳定的充分条件。

An epidemic disease caused by an infection by human immunodeficiency virus (HIV-1), a retrovirus that causes immune system failure and debilitation and is often accompanied by cancers and secondary infections such as but not limited to tuberculosis.

一种由免疫缺陷病毒感染的人类传染病(HIV-1)，一种逆转录酶病毒引致免疫系统失效或者衰弱和经常伴随着癌症或者第二传染病例如肺结核，但不限于肺结核。

Firstly, we consider SIQR epidemical models with continuous and pulse vaccinations; the reproduction numbers have been obtained for those models; by using Dulac function, we prove the global stabilities of equilibrium of SIQR model with continuous vaccination. In the SIQR epidemical models with pulse vaccinations, we have also discussed the existence of the infection-free periodic solution, the global stabilities of the infection-free periodic solutions, and the effectiveness of pulse vaccination and continuous vaccination policies has been compared for the two models.

文中首先考虑具有连续免疫接种和脉冲免疫接种的SIQR传染病模型，分别获得了它们各自的基本再生数；利用Dulac函数方法证明了具有连续免疫接种的SIQR模型无病平衡点的全局渐近稳定性；在脉冲免疫接种下SIQR传染病模型里，讨论了无病周期解的存在性，证明了该周期解的全局渐近稳定性，并且对连续和脉冲接种下的SIQR传染病模型的接种效率进行了比较。

Global warming a direct impact on respiratory diseases, allergy and infectious diseases, particularly malaria, lymph nodes filariasis, schistosomiasis and hookworm disease, cholera, meningitis, kala-azar, dengue fever and other infectious diseases will endanger the tropical regions and countries, some At present mainly in tropical areas with the disease may be warming to the spread of mid-latitude regions.

全球增暖直接影响呼吸器官疾病、过敏和传染病，特别是疟疾、淋巴腺丝虫病、血吸虫病、钩虫病、霍乱、脑膜炎、黑热病、登革热等传染病将危及热带地区和国家，某些目前主要发生在热带地区的疾病可能随着气候变暖向中纬度地区传播。

Hydrophobia, AIDS, tuberculosis, viral hepatitis, gonorrhea and syphilis are the major infectious diseases which should be prevent in Qingyuan for the future.

狂犬病、艾滋病、肺结核、病毒性肝炎、淋病和梅毒等传染病是今后清远市传染病预防控制工作的重点。

ConclusionThe main infectious diseases in Cheng jiang are intestinal infection from 1996 to 2005,among which,the main influencing factors are typhoid and paratyphoid.

结论澄江县1996～2005年的主要传染病是肠道传染病，其中伤寒副伤寒起主要影响因素，伤寒副伤寒得到有效控制是降低我县传染病发病的关键。

Foot and mouth disease is a highly contagious disease of cloven-hoofed animals. It is one of the most important animals infectious diseases. It is defined as A class animals infectious disease by OIE and Our Country .

口蹄疫是由口蹄疫病毒(foot and mouth disease virus， FMDV)感染引起的偶蹄动物的高度接触性传染病，是世界上最重要的动物传染病之一，国际兽疫局及我国都将该病列为A类家畜传染病之首。

Results The nurses in the centers of blood decontamination understood less concerning the laws and regulations on contagions. Their main knowledge on contagion protection came from clinical practice. The demands focused on the training of occupational protection theory. The protective measures the nurses took were associated to their roles,positive answer of nurse was better than that of assistant nurse.

结果血液净化室护理人员对传染病法律法规了解较少；护理人员传染病防护知识主要来自临床实践；传染病防护知识需求主要是职业防护系统理论培训；护理人员应对方式与工作角色有关，护士的积极应对明显好于助理护士(P.05)。

After the democratic reform, the Chinese Government has made great efforts to strengthen the prevention against and control of infectious diseases, the contagious diseases and endemics that used to seriously affect people's health have been efficiently controlled and even eradicated, and the disease rates of mortalities of contagious diseases have noticeably decreased.

民主改革后，中国政府大力加强疾病预防控制工作，严重影响人民群众身体健康的传染病、地方病得到有效遏止，传染病发病率和死亡率明显下降。50年代末开始在西藏开展牛痘疫苗、霍乱疫苗的预防接种，有效控制了天花、霍乱等传染病发生。60年代初西藏自治区卫生防疫站建立，开始建立疫情报告制度。
