When these oils are heated, their viscosity is reduced, and they can be burned directly in a diesel engine, or the oils can be chemically processed to produce fuels such as biodiesel.
当这些植物经过加热后粘稠度降低，便可直接在柴油机内燃烧，或者将部分油类经过化学方法加工为生物柴油。

Flow around an obstruction causes a decrease in melt front speed and leads to high local viscosity and reduced relaxation.
围绕障碍物流动使融化前部的速度下降并产生较高的局部粘性而减少松弛作用。

Carbon dioxide and carbon monoxide and mineral oils are a solubility, can make the oil viscosity is reduced, if there is water, it produces corrosive carbonic acid.
