For it is difficult to get the carbon-hydrogen ratio of gasoline during themeasuring of petrol fuel consumption with carbon balance method, according to therelationship between carbon-hydrogen ratio and gasoline density, a simple mathematicalmodel is derived as a new method for the measuring of gasoline carbon-hydrogen ratio inpractice.

The paper has bult up of a formula for calculating the standard heats of formation of hydrocarbons by ananlysing the relation between △△_fH~0(R—G/CH_3G) and the elextronegativity of group G:△_fH~0(RG)=△_fH~0(CH_3G)+(1.

This paper compares the physical characteristics of R502 and some hydrocarbons of interest asrefrigerants, the results indicate that R1270 is a favorable alternative for R502.

The emission of hydrofluorocarbons (HFCs), perfluorocarbon (PFCs) and sulfur hexafluoride (SF 6 ) from China in 1995 are estimated primarily as 2 244 t, 2 581 2 t and 215 t, which account for 0 9%, 6 45% and 3 7% of the world total emission, respectively.
