effective density meaning in Chinese
土的物理性质有效密度
有效密度
Examples
- Study on computing method of aggregate effective density and asphalt mixture ' s volume parameter
基于图像的粗集料形态对沥青面层抗剪性能的影响 - Methods of dust character test - part 2 : determination of effective density - pyknometer method
粉尘物性试验方法第2部分：有效密度的测定比重瓶法 - The effective density of basalt is the emphases of the research of aggregate , the effective density of aggregate is a very important factor in mix design for asphalt concrete , but the method how to get it is much more difficult than to get the apparent density or the bulk density of aggregate , we get a statistical formula to get the effective density by the apparent density and the bulk density
其中集料研究主要是玄武岩的有效密度测试方法，集料有效密度指标在沥青混合料设计中至关重要，但集料有效密度试验较为麻烦，而表观密度、毛体积密度的试验较为简单且有统一的标准，为此论文通过对试验路料场集料的一系列试验获得现场集料的表观密度、毛体积密度、有效密度之间的统计规律。
