分车道行驶轮迹横向分布频率曲线显示,渠化程度较高的高速公路水泥混凝土路面磨损破坏主要集中在行车道轮迹峰值范围。
To the structure of the internal market as the standard, can be divided into wheel axis, multi-core type, mesh type, mixed type and intangible so five large factory-type model.
以内部市场结构为标准,可划分为轴轮式、多核式、网状式、混合式和无形大工厂式等五种模式。形成区域特色产业集群,是实现苏北新型工业化又好又快发展的必要选择。
