Granted the weight and the specific gravity of a body, we can calculate its volume. 假设已知一个物体的重量和比重(SP GR),我们就能算出它的体积。
True density and specific gravity of your sample are displayed. 样品的真密度和比重(SP GR)都能够显示出来。
Specific gravity is the ratio of the density of a substance to the density of water. 比重(SP GR)是某物质的密度与水的密度之比。
Hazards to human life and to the marine environment; the effect of specific gravity and solubility; danger from vapour cloud drift and the jettisoning of cryogenic liquids. 对人命和海洋环境的危害;比重(SP GR)和溶解度的影响;蒸气团漂流的危险和投弃低温液体的危险。
Therefore, using higher specific gravity and dynamic viscosity of biodiesel is able to decrease fuel injection pressure properly. 由此结果可知、比重(SP GR)和动力黏度较高的生质柴油,可适当的将燃料喷射压力减低是可行的。
