摘　　要：总结分析各种测沙仪器的适用性和优缺点,提出基于比热容原理测量含沙量的方法,在15℃实验条件下进行浑水含沙量与比热容的关系测定试验,室内试验测量范围为10～1000kg/m3,测得该条件下含沙量与比热的倒数值呈良好的线性关系,初步提供实用比热容测沙仪的逻辑功能部件的设计思路,为测沙仪的发展提供一种新的途径。The article summarizes the advantages and disadvantages of the exist-ing suspended sediment meter and puts forward a new method of measurement of sediment concentration on the basis of the principle of heat capacity. Under the conditi-on of 15 ℃, the experiment of determining the relationship between muddy water sediment concentration and the specific heat, which has a measuring range of 10- 1 000 kg.m3, proves that it has a good linear relationship sediment concentration and the reciprocal of the specific heat capacity betmeen. It also provides a design thought of logical structure component of specific heat capacity suspended sediment meter. It provides a new approach for the development of suspended sediment meter.
