Once the desired specific gravity is established, the same strength must be used henceforth . 所需的比重一经确定,以后就必须使用同一浓度的酸。
In this range, the pressure drop increases in proportion to the specific gravity of the mixture . 在这个范围内压力差的增加与混合物的比重成比例。
The specific gravity of a material is the ratio of its density to that of water and is therefore a pure number . 物质的比重指的是物质的密度与水的密度的比值,所以是纯数。
The clinician is best guided by evidence of a water diuresis as indicated by observation of the urine specific gravity . 临床上最好的办法是通过观察尿的比重作为水利尿的指示。
The nature of sand movement depends on the particle size, shape, and specific gravity in respect to the associated velocity and turbulence . 泥沙运动的性质取决于颗粒的大小、形状和比重并与流速和紊动有关。
A check of urine specific gravity at the time of admission of an acute asthmatic will invariably show a state of severe water retention with high urinary specific gravity . 此时检查急性气喘病患者的尿比重,将发现他们都处于水潴留与尿比重高的状态。
