The aim of this study was to determine the frequency of infectious diseases among people entering/exiting via Manzhouli port. We analyzed infectious disease data from the Manzhouli International Travel Health care Center covering 2012 through 2014, as well as performed several laboratory tests to measure rates of infection. The frequencies of infectious diseases as well as their association with occupation and year of occurrence were calculated for people entering and exiting via the port. The total proportion of infectious diseases measured was 2.18%. Hepatitis B was the most commonly occurring at 1.68%, followed by syphilis, hepatits C and HIV, which were 0.23%, 0.21% and 0.04%, respectively. Contract workers, traffic staff, foreigners and those married abroad were more likely to be infected. Furthermore, there were significant differences among three years. Strategies should be developed and preventive policies should be implemented aimed at protecting the at risk populations at Manzhouli port, especially with regard to contract workers, traffic staff, foreigners and those married abroad.

基于时频对偶原理,提出了一种准正交时分复用(QOTDM)系统.该系统利用频域具有升余弦性质的脉冲波形的平移准正交特性,采用自适应信道均衡方法,使发送滤波器、信道和接收滤波器的频域总特性具有升余弦性质,信道等效脉冲响应满足奈奎斯特采样点无失真准则.发送端利用上述信道进行时域波形准正交的离散信息符号序列传输;接收端根据信息符号波形的准正交特性,实现准正交分离.与正交频分复用(OFDM)系统相比,QOTDM系统在略微降低频带利用率的条件下,可以降低峰值平均功率比,并且当信噪比较高时具有更强的抗多径衰落能力.仿真结果表明,在准静态多径衰落信道下,采用正交幅度调制,在误比特率为10-3时,QOTDM比OFDM的平均比特信噪比值约低3 dB.

Animal Husbandry and Feed Science 2016年第4期8卷 230-233页

作者： Deng Huifen Liu Hailin Wu Baixin yi Kangle Jiang Guitao Li Haobang sun Ao Hunan Biological Electromechanical Vocational Technical College Changsha 410130 China Hunan Institute of Animal and Veterinary Science Changsha 410130 China

A comparative study was conducted on four mulberry（ Morus alba） varieties（ lines） in Hunan dry land from the aspects of production performance,nutritional composition and amino acids content. The result showed that the four mulberry varieties all adjusted well to soil,climate and other natural conditions in Hunan province,presenting good growth. The dry matter content of four varieties（ lines） was above 25% and the crude protein content was more than 22%. Although the crude protein and total amino acid content of four mulberry varieties were lower than that of soybean powder,the proportion of various amino acids tended to be consistent,so mulberry leaf was very comprehensive in nutrition as an animal feed. Yuesang 11 had the highest fresh yield and crude protein of 14. 28 t / hm^2 and23. 22% respectively; Guisangyou 12 had the highest total amino acid content of 19. 58%. There were differences among four varieties,but each variety had its own advantages,so they all had good popularization value.
