解釋
含砂的-
A true links course laid out on a raised - beach, laden with brown sand forming the undulating links with its land some 3 yards to 10 yards above sea level
盛滿棕色砂礫的凸起的海灘形成了波浪式的場地，地面高於海平面3到10碼。 -
The turbulent characteristics of high - velocity sediment - laden and aerated flow are more other than the clear water flow of single - phase and current of low speed. in a special circulating system with high velocity flow, some flow parameters such as boundary shear stress and pulsation pressure are measured. an investigation is made on the turbulent characteristics of the three - phase flow of water, air and sand
本文針對高速含沙摻氣水流的運動規律有別于低速水流及清水單相流，在自己研製的高速渾水循環系統中，通過對高速含沙摻氣水流壁面剪切應力和脈動壓強等參數的量測，分析了水沙氣三相流的紊動特性，探索了泥沙對固壁的磨蝕機理及減蝕措施，其主要內容包括以下幾個方面： 1 -
Based on this evidence, a new hypothesis has been suggested where the spots are caused by explosive jets of sand - laden co2
根據這項證據，一項剛被提出的假說認為，這些暗斑是由飽含砂塵的二氧化碳噴流所造成的。 -
The surface material is liable to erosion wear with high - velocity sediment - laden flow, hi this paper, sand wear mechanisms are discussed and some effects of significant flow factors on material wear are analyzed ; the possibility of preventing erosion wear with aeration is proposed ; based on test data, the formula for calculating the concrete material wall surface wear rate is derived. it is indicated that the wear rate is related to the air concentration, the strength of material, the flow velocity and the sediment content. it is shown that wear rate can be reduced with the help of flow aeration
分析了空蝕與磨蝕的不同物理特徵；探討了沙粒磨蝕機理，提出了影響磨蝕vi河海大學博士學位論文一的因素；研究了摻氣抗磨的可能性：建立了混凝土材料壁面磨蝕率的計算公式；說明含沙水流對固壁材料的磨蝕率隨摻氣濃度、材料強度的增大而減小，隨水流流速、含沙量的提高而增大；利用摻氣可有效地降低過流表面的泥沙磨蝕率。 -
Analysis on silt - discharge distribution and variation character of sediment - laden and coarse sand producing region in the middle yellow river
