长江中上游集装箱码头型式和装卸工艺系统研究

从码头型式和码头前沿装卸工艺两方面提出了提高长江中上游斜坡码头装卸效率的措施，并对文中所提出的各种装卸工艺系统进行了码头通过能力计算，以供长江中上游集装箱码头改建和新建时参考。     

Research on the Variable Steering Ratioof Four-Wheel-Steering Vehicle

The steering characteristic of afour-wheel-steering vehicle is numerically simulated for in-depth research of the handling stability offour-wheel steering．The research results show that the deteriorating tendency of the steering stability due to the increase of the vehicle speed is improved obviously in the case of four-wheel steering．The approach of variable steering ratio is discussed.The use of the variable steering ratio can not only raise the steering stability of vechicles at high vehicle speed，but also reduce the dicomfort and steering burden of drivers；and hence is helpful for the subjective evaluation of four-wheel steering vehicles．     

国内外船携式溢油回收系统比较

比较了国内外四种船携式溢油回收系统,由于其扫油臂的结构和撇油器的原理不同,因而整个回收系统性能也有所差别。
