作者： HUSheng Shou kong ling zhi GAO Run Lin ZHU Man Lu WANG Wen WANG Yong Jun WU Zhao Su CHEN Wei Wei LIU Ming Bo For the editorial board National Center For Cardiovascular Diseases Beijing 100037 China Ministry of Health of the People' Republicof China Beijing 100044 China Beij'ing Tiantan Hospital Beijing 100050 China Beijing Anzhen Hospital Beijing 100029 China

Major and profound changes have taken place in China over the past 30 years. Rapid socioeconomic progress has exerted a great impact on lifestyle, ranging from food, clothing, working and living conditions, and means of transportation to leisure activities and entertainment. At the same time, new health problems have emerged, and health services are facing new challenges. Presently, cardiovascular diseases （CVD） are among the top health problems of the Chinese people, and pose a serious challenge to all engaged in the prevention and control of these diseases. An epidemic of CVD in China is emerging as a result of lifestyle changes, urbanization and longevity. Both national policy decision-making and medical practice urgently need an authoritative report which comprehensively reflects the trends in the epidemic of CVD and current preventive measures. Since 2005, guided by the Bureau of Disease Prevention of the Ministry of Health of the People＇s Republic of China and the National Center for Cardiovascular Diseases of China, nationwide experts in the fields of epidemiology, clinical medicine and health economics in the realms of CVD, cerebrovascular disease, diabetes and chronic kidney disease, completed the Report on Cardiovascular Diseases in China every year. The report aims to provide a timely review of the trend of the epidemic and to assess the progress of prevention and control of CVD. In addition, as the report is authoritative, representative and readable, it will become an information platform in the CVD field and an important reference book for government, academic institutes, medical organizations and clinical physicians. This publication is expected to play a positive role in the prevention and control of CVD in China. We present an abstract from the Report on Cardiovascular Diseases in China （2010）, including trends in CVD, morbidity and mortality of major CVDs, up-to-date assessment of risk factors, as well as health resources for CVD, and a profile of

作为深度学习的一种有效算法,深度卷积网络已成功应用在处理图像、视频和音频等领域.通过建立一卷积神经网络模型并应用于网络入侵检测,选取的卷积核与数据进行卷积操作提取特征的局部相关性从而提高特征提取的准确度.采集到的网络数据通过多层"卷积层-下采样层"的处理对网络中正常行为和异常行为的特征进行深度刻画,最后通过多层感知机进行正确分类.KDD 99数据集上的实验表明,文中提出的卷积神经网络模型与经典BP神经网络、SVM算法等相比,有效提高了入侵检测识别的分类准确性.

The prevalence of cardiovascular diseases （CVDs） is associated with the socioeconomic prosperity, lifestyle changes, accelerated process of ageing and urbanization. The prevalence of CVDs is continuously increasing in China and will remain an upward trend in the next 10 years. CVDs are the leading cause of death for Chinese in both urban area and rural area. Nowadays, 41.09% of deaths in rural area and 42.52% of deaths in urban area are caused by CVDs in China. The burden of CVDs remains heavy and has become an important public health problem. Effective strategies should be enforced urgently for the prevention of CVDs under the supervision of the government. In 2012, the Ministry of Health of China and 14 governmental departments jointly issued the Work Plan for Chronic Disease Prevention and Control in China （2012-2015）, a guideline for the prevention of chronic diseases, especially CVDs in China.

为提高柱塞泵的容积效率,探讨了残留容积和柱塞副间隙对柱塞泵效率的影响。通过理论分析可得,减小残留容积可以提高柱塞泵的容积效率,但是过小的残留容积,会使柱塞产生"咬死"现象,可以增大柱塞副间隙来改善。结合柱塞的状态平衡方程,推导出柱塞副周向摩擦力的受力方程,分析表明,随着柱塞副间隙的减小,柱塞副的周向摩擦力也减小,而柱塞泵的机械效率在增大。调节残留容积可以提高柱塞泵的效率,通过比较可以获得最佳残留容积和柱塞副间隙。
