All other common gases are cooled by expansiontemperature and below it.
所有其它普通气体在室温和室温以下时都会因膨胀而冷却。
2
At a relatively high pre-expansiontemperature, the particle size increased with the increasing of extraction temperature.
随着萃取温度的升高,在相对较高预膨胀温度下,粒径随着萃取温度升高而增大。
3
Decreasing the diameter of nozzle, increasing the concentration of cosolvent or decreasing the pre-expansiontemperature could result in the diameter reduction of the microparticles.
