So it is significant for harmful substance control of engine to be researched on influence of equal temperature time playing on emission of engine in cold-start,and getting qualitative conclusion through analysis on test and course.

A discussion on hydrocarbon accumulation dating determined by homogenization temperature and burial history of fluid inclusions——An example from the Fushan depression,Beibuwan basin;

The time of petroleum accumulation in the Shiwu fault depression of the southern Songliao basin is determined according to the studies of structural evolution,hydrocarbon-generating history of source rocks and homogenization temperature of fluid inclusions.

Microscopic inspection,microthermometry and salinity measurement,systematic fluid inclusion studies in the Qingshen gas field of the Songliao Basin show that homogenization temperature of fluid inclusion varies from 97.

Study of Application in Crude Oil Average Temperature in Oil Tank Based on Soft-instrumentation Techniques;

Equivalent-trapezoid method of average temperature calculation for multi-row-pipe straight frozen soil wall

The thickness,the average temperature and the frozen time are obtained from FEA.

Then,the transition relation between the surface temperature and mean temperature is provided to r.

Based on the characteristics of temperature field inside frozen walls , a detailed discussion is made on the relationship between the temperature of the side wall and the mean temperature of the frozen walls ,and the effective thickness and bearing capacity.

Analyses the unreasonability of hydraulic calculation based on the mean temperature 60 ℃ in a heating system with 95 ℃/70 ℃ hot water.
