This paper introduces the actualities of communication of freeway roadside and points out the problems.
文章首先介绍快速道路路边通信现状并指出存在的问题 ,结合美国NTCIP(NationalTransportationCommu nicationsforITSProtocol) ,探讨了路边通信协议。
Stabilizing side slope of highway by using Vetiveria zizanionides technique had obvious economic and ecological benefits that its afforestation cover rate reached 90%, but the cost correspond from one fifth to one tenth of engineering measure.
采用香根草生物技术措施进行公路边坡治理,投入成本仅为纯工程措施的1/5～1/10,绿化覆盖率达90%以上,经济和生态效益明显;香根草配方基质育苗种植和合理施肥技术的运用,使种植的香根草成活率提高近30%;香根草在锰矿渣边坡种植成活率71%,坡面覆盖达50%,证明香根草能够在有毒的废矿上生长。
In accordance with the high level of water and soil losses in the period of construction of high way,the soft way for stabilizing the slope of highway is necessary and some benefit and shortage was analysed,the right way of Vetiver grass technology for stabilizing slope of highway was confirmed.
针对我国公路建设中存在严重的水土流失现象 ,分析了香根草等高植物篱技术在公路边坡防护中出现的一些问题 ,确定了运用软性措施进行公路边坡防护的必要性和正确运用香根草进行公路边坡防护的方
