The kinds and contents of minerals in profile might be increased by aggravation of weathering of the soils.
剖面随风化强度的加剧，所含粘土矿物的种类增多，质量分数也相应的提高。And looked into the hole, found out when used No. 4 composition surfactants, the foamed phenolics are best, and the best dosage is 8%.
从而得出当采用4号表面活性剂体系时，泡沫塑料的综合性能最优。并得出4号表面活性剂的最佳质量分数为8%。Under certain conditions, this rule can also be used to estimate the quality factor of the structural components in the alloy.
在一定的条件下，利用杠杆法则也可以估算合金中各组织组成物的质量分数。It is found that the sintering properties of andalusite can be enhanced obviously by addition of magnesia, especially at high temperature.
结果表明：加入氧化镁可明显促进红柱石的烧结，在高温阶段其作用更加明显，但其质量分数必须严格控制，不宜超过2%。We found that the viscosity of nanofluids increases with an increase in the mass faction of Cu particles.
研究发现纳米流体的粘度随着颗粒质量分数的增加而增加。For the higher polymer concentration solution, approached the maximum viscosity required more amount of surfactant.
聚合物质量分数越高，达到最大黏度值所需的表面活性剂的量也越大。the following examples illustrate , but do not limit , the invention . the parts are by weight.
下面的例子描述，但不限于此，此发明。组成为质量分数。The dependence of the solution shear viscosity on the shear stress, temperature and cellulose material content was investigated.
考察了剪切力、温度、纤维素原料质量分数对溶液表观粘度的影响。and the scorch time reduced and the curing speed increased as the moisture content in carbon black increased beyond a certain level.
炭黑中水分质量分数超出一定范围时，影响胶料的焦烧时间及硫化速度。
