Firstly,the thermal post-buckling equilibrium paths of the FGM rod with different gradient index in the uniform temperature field were plotted,and compared with the behaviors of the homogeneous rods made of ZrO-2 and Ti-6A1-4V materials respectively. For given value of end rotation angles,the influence of gradient index on the thermal post-buckling behaviors of FGM rod was discussed.

Compared with a homogeneous porous medium (HPM) burner, the GVPM burner is of more uniform temperature profile, lower CO and NO_ x emissions, higher flame speed, better stability, larger range of combustion limits and higher power modulation.

Secondly, the structure reaction under instantaneous temperature load was analyzed. After the way to change nonlinear temperature field to its equivalent linear temperature field was introduced, the influence of temperature grads as to internal force and displacement of the structures was researched .

Through theoretical analysis and experiments, the viscoelastic mechanical model of optical fiber coupler in the process of fused biconical taper was established, and the numerical analysis in non-uniform temperature field was made.

A design method which will ensure a uniform temperature field at the active blades of a gas turbine with external air-liquid cooling has been developed and also proved out experimentally, as the results shown here indicate.

A method is proposed for designing the profile of a slot channel so as to ensure a uniform temperature field in the cooled object.

A general theory for snap-through buckling of an open bimetallic shallow spherical shell under uniform temperature field is presented in this paper. It relates the critical buckling temperature both to physical and geometrical parameters of the shell, including the extent of its central opening as another important factor. Furthermore, they are expressed accordingly by various practical curves. While reducing to the special case of a closed shallow spherical shell, present theory appears to be in good agreement...

A general theory for snap-through buckling of an open bimetallic shallow spherical shell under uniform temperature field is presented in this paper. It relates the critical buckling temperature both to physical and geometrical parameters of the shell, including the extent of its central opening as another important factor. Furthermore, they are expressed accordingly by various practical curves. While reducing to the special case of a closed shallow spherical shell, present theory appears to be in good agreement with earlier work by Wittrick.According to the selection of reference surface of coordinates as suggested by and Radkowski, the basic equations for a double-layered shell are first simplified in forms similar to those of classical shell theory. By analogy, the thermal effect is replaced by an equivalent edge-moment loaded uniformly along both boundaries of the shallow spherical shell. The problem is then solved according to Hu's simplified method, but with some vital modifications. From the results of numerical computations, the paper gives some rather interesting conclusions, which may be valuable in designing the elastic elements of various instruments in engineering.

The average temperature measurement of an uneven temperature field in a wind tunnel by a thermououple assembly is carried out in the following way: that the various measuring ends are arranged in an even and equidistant distribution within the cross section of the wind tunnel, thus the required temperature can be obtained by means of a potentio-meter in a single measurement. This method is better than that of the copper wire reistance net measurement as used in our courtry. Experiments have showing evident reduction...

The average temperature measurement of an uneven temperature field in a wind tunnel by a thermououple assembly is carried out in the following way: that the various measuring ends are arranged in an even and equidistant distribution within the cross section of the wind tunnel, thus the required temperature can be obtained by means of a potentio-meter in a single measurement. This method is better than that of the copper wire reistance net measurement as used in our courtry. Experiments have showing evident reduction of heat balance errors.A brief description in also made here of the climination of some measuring errors which should be avoided, and in the fabricating and checking of thermocouple assembly.

In this paper we calculated the temperature fields of high temperature and high pressure vessel by finite element method, and discussed the influences of various factors on the temperature fields. The calculation results showed that in order to obtain rather homogeneous temperatures in the rock sample it is necessary to select suitable length of the heater and the appropriate winding. In order to decrease the temperature of internal sides of the vessel and the power expense, it is very important to improve the...

In this paper we calculated the temperature fields of high temperature and high pressure vessel by finite element method, and discussed the influences of various factors on the temperature fields. The calculation results showed that in order to obtain rather homogeneous temperatures in the rock sample it is necessary to select suitable length of the heater and the appropriate winding. In order to decrease the temperature of internal sides of the vessel and the power expense, it is very important to improve the design of the insulator. The results of the calculation for the unstable state pointed out the relationships between the heated rate, the time occurred and the value of maximum temperature difference in the rock sample. At the same time, we obtained results from the analog method by means of resistance network. The results were compared with that of the finite element method, and they are in good agreement.
