1： gaseity content , total sulfur content is at 0℃、101.35kPa.
2：can measure sample whether it exists free water by eyeballing when measuring density.
a
evaporation pressure can be evaluated by GB/T 12576， measured by GB/T 6602 when arbitration。
b
component can be measured by SH/T 0230，but measure by SH/T 0614 when arbitration.
