模型沙 meaning in Chinese
model material
model sand
Examples
- Experimental research on physical characteristics of compound model sands made of hydrophilic resin
亲水性树脂基复合模型沙力学特性试验研究 - It is hard to modify or control the shape of model sand by common ways of comminution
通常的粉碎方法时塑料模型沙不规则颗粒形貌的控制和改善是十分困难的。 - The shape of model sand particle play an important role in submarine rest angle , starting speed , bulk specific weight and some other physical characters
摘要颗粒形貌对模型沙的水下休止角，起动流速、堆积密度等性能有显著影响。 - Even the chemical synthesis model sand can not satisfy the need of silt dynamics research in different similar scale for the expensive self - cost and unchangeable density
而采用合成的树脂颗粒作为模型沙，成本较高，且过于圆滑，亦不能根据相似比尺的要求调整其密度，给泥沙动力学研究造成不便。 - According to the similar rule , a movable bed model for downstream channel and the particle size distribution of the model silt in the channel and the scour hole are designed . a theoretical method of size distribution in the scour hole is devised
根据模型律设计了太平湾尾水渠动床模型，分别确定了河床中和冲刷坑中模型沙的配比，并对冲坑中的床质级配进行了理论推导。
