    Physico chemical changes of the foaming agent OBSH during heating up are studied by the differential thermal analysis technique. It is found that the differential thermal curve has 3 exothermic peaks, their tip temperatures being in order of 175℃, 225℃ and 568℃. The three peaks are identified to be corresponding to thermolysis, phase transformation and oxidation of OBSH, respectively.

  summit temperature
A divergence in loop cross-section increases the summit temperature by typically a factor of 2, and decreases the density, while an increase in loop height (for constant loop length) changes the temperature very little but can halve the density.
      
Numerical solutions are presented for the summit temperature and heating in a thermally isolated coronal loop that is in hydrostatic equilibrium.
      
On increasing the cross-sectional area the summit temperature generally increases slightly except for warm loops where no increase in temperature is recorded and hot-cool loops where a dramatic increase in summit temperature may occur.
      
The distribution of the heating has a significant impact on both the summit temperature and the temperature distribution along the loop.
      
In each case the ratio between the heat deposited and radiation provides a scaling for the summit temperature.

The results of DSC (differential scanning calorimetry) and TGA (thermo-gravimet-ric analysis) indicate that after the treatment, the peak temperature of thermal decomposition of Newcell fiber increases 11Cwhile that of Tencell fifber increases 11~17C, and the max temperature of weight change rate of Newcel rises 10~11C whilethat of Tencell rises 10~17C. After being treated with certain concentration alkali, the crystallite size of Lyocell fiber increasesand the original crystal defect disappears or reduces, so the thermal stability of it increases.

采用保持原长方式在不同碱浓度下处理Lyocell纤维(Newcell和Tencel纤维),探讨碱处理对Lyocell纤维热稳定性的影响。DSC和TGA结果表明,碱处理Newcell纤维与未处理Newcell纤维相比,热分解峰顶温度提高了11℃,重量变化速率最大温度提高了10~11℃;碱处理Tencel纤维与未处理Tencel纤维相比,热分解峰顶温度提高了11~17℃,重量变化速率最大温度提高了10~17℃。Lyocell纤维经一定浓度的碱处理后,增加了纤维的晶粒尺寸,消除或减少了纤维原有晶体的缺陷,从而提高了纤维的热分解稳定性。
