Integrative design model and algorithm for nano-satellite s radiator surfaces and heat insulation layers;

To avoid a long nozzle (LN) of non-preheating from rupture, a heat insulation layer (HIL) with a lower coefficient of thermal conductivity (CTC) was compounded in the inner hole, and the thermal stress was investigated.

Experimental research on insulating layer heat transfer performance of a low temperature test chamber;

A heat-transfer character experimental analysis on insulating layer for environmental test chamber;

The cement pressing-in under the bottom plate is to fill up the gap of carbon ramming mass layers between the bottom plate and I-beam, in order to prevent the forming of air heat insulating layer and to improve the heat transfer effect in furnace bottom.

Heat resistant conveyor belt was developed by the method of forming high strength protective layer through high temperature carbonization of heat insulating layer.

The study of the stability of roadbed on different locations of the heat insulating layer in seasonal frozen area can present theory reference for the prevention of road disease in the seasonal frozen area of our country.

Based on the observed data,the distribution characters of the air temperature,ground temperature,and temperature on two sides of an insulation layer in this tunnel,were analyzed.

In order to keep the surrounding rock of tunnel from thawing,the usual measure is to place an insulation layer between the linings.

In view of reduction of irreversibility,a new design principle of the low temperature system insulation is proposed according to the thermodynamic second law.
