In general, the design work with traditional measures is done by hand, which cannot meet the needs of the technology and manufacture. So the author has developed a CAD hydraulic design software fit for lower specific speed axial flow runner, which is easily operated by users.The main research work of this paper is as follows:1 Analyzing the main reason of axial flow power station cannot work well under littler volume of flow in some season and putting forward an improving scheme, pointing out the characters of design under abnormal factors.2 Combined with the development of the industry in our country, the abnormal hydraulic design method of propeller turbine is discussed based on present literature, data and experiment results.3 Guided by the design method of software engineering, a suit of hydraulic design software of Lower Specific Speed Axial Flow Runner is programmed by the object-oriented programming language Visual Basic and a straightforward, concise and standard Windows human-computer dialogue interface is designed for the system, which makes the operation of the system very convenient.4 ActiveX Automation technology is adopted as the interface with AutoCAD and the hydraulic drawings are edited, modified by AutoCAD until hydraulic model drawings according with the demand of engineering practice are output.5 To resolve practice problem, the author has designed a lower specific speed axial flow runner for Duowa Power Station through an example.

"The take-home message of this study for clinicians is that obese people with asthma need to be followed more carefully because it's harder to control their asthma, so they are more likely to end up in the hospital," said study coauthor Michael Schatz, MD, chief of allergy at Kaiser Permanente San Diego Medical Center, California."My advice for obese asthmatics is: be vigilant to keep your asthma symptoms in check, make sure you know what to do when your symptoms worsen, and do whatever you can to lose weight."

研究共同作者、加州圣地牙哥Kaiser Permanente医学中心过敏科主任Michael Schatz医师表示，本研究提供给医师们的重点是，肥胖气喘患者需要仔细地追踪，因为会比较难控制他们的气喘，所以他们比较可能住院；我对于肥胖气喘患者的建议是，对于自己的气喘症状要有所警惕，确保知道当症状恶化时应该如何处置，且尽可能减重。

It is found that the distributed microscopic traffic network simulation methods based on distributed systems require not only the careful discussions on traditional traffic flow theory, such as the driver's uncertain behaviors in selecting the route and changing lane, but also some deep researches on parallel techniques. These key techniques about how to realize parallel and distributed simulations include how to partition the large-scale road network into sub-areas, how to divide the multi-course in dynamic traffic flow operation, how to finish the informational transmission among processors, and how to realize the clock-synchronization among processors etc..

在基于分布式系统的路网交通流并行微观模拟研究中除了需要对传统的交通流理论如驾驶员路径选择、车道变换等微观不确定性行为进行仔细探讨外，还必须对道路网子网的划分方法，交通流动态运行过程中多个进程的划分方式及各进程之间消息传递、各处理器间的时钟同步方式等实现并行的关键技术问题进行深入研究。
