  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.
      
  peak temperature
The possibility of reconstructing a two-peak temperature distribution by the proposed method is demonstrated.
      
Effect of orientation on the peak temperature of the yield-stress anomaly in single crystals of the Ni3Ge alloy
      
Temperature dependence of the yield stress τc(T) and shear stresses, as well as the orientation dependence of the peak temperature Tp of the yield-stress anomaly have been studied on single crystals of the Ni3Ge alloy.
      
The peak temperature Tp corresponds to the maximum in the τc(T) dependence.
      
It is shown that in the case of the above equality it is possible to describe the orientation dependence of the peak temperature Tp of the temperature anomaly of the yield stress in single crystals of Ni3Ge.

The curing reaction of two kinds of UF resins has been studied, namely, for plywood (F/U=1.7) and for particleboard (F/U=1.63), in the presence of NH_4Cl hardener The result shows that there is a clear exothermic peak below 100℃ with NH_4Cl. The temperature of the. peak (Tp) hardly changes at a definite time range, bout the exothermic heat (ΔH) and the height of the peak lower with time The Tplowers and the height of the peak rises with increase of NH_4Cl amount, when the amount is about 1.5%(based dry resin)both of them are no change.The exothermic peak is concerned with the disappearance of the group-CH_2OH, and then a primary curing reaction of UF resin takes place. The curing reaction order is 1.5, the active energy is 80 KJ/mol with 1.7% NH_4Cl (based dry resin) according to kissinger's method by DSC.

应用差示扫描量热法(DSC)研究表明,液体脲醛树脂加入氯化铵后,在敞开体系中,温度在100℃前出现明显的放热峰,峰顶温度在一定的放置时间内不变,对应的放热量有下降的趋势;峰顶温度和峰高随氯化铵增加而变化,在氯化铵用量到达1.5%左右时(以固体树脂计),二者均不再变化。作者认为,放热峰对应于树脂的初步固化,与羟甲基消耗有关。采用Kissinger方法求出反应的活化能为80±3KJ/mol,反应级数1.5。

Oxygen chemisorption capacities of four sulfided alumina-supported Mo-Ni catalysts were determined by static adsorption method at -78℃.A linear relationship between the low temperature O. chemisorption (LTOC) and residual nitrogen in oil product was observed. It indicates that the LTOC method can be used to distinguish the small difference in hydrodenitrogenation (HDN) catalyst activity. Temperature-programmed surface reaction (TPSR) was used to study the catalyst after O2 chemisorption in 4.8% H2/Ar. Only a peak on the TPSR spectra was observed, the lower the peak temperature, the higher the activity is.It suggests that the strength of O2 chemisovbed bond is also related to /the HDN activity. After hydrogen reduction, the ESR signal of the catalyst chemisorbed with O2 is the same as that before O2 chemisorption, therefore, no structure change takes place caused by O2 chemisorption.

应用静态法测定了四种硫化Mo-Ni催化剂的低温氧吸附量及氧吸附后的原位氢程序升温表面反应,并测定了过程中的ESR信号。获得了氧吸附量与加氢脱氮生成油中含氮量(<20ppm)的线性关系,表明低温氧吸附方法可鉴别活性差别较小的催化剂。氧吸附后的原位H_2-TPSR显示一个谱带,峰顶温度较低的催化剂的加氢脱氮活性较高,因此O_2吸附键的强弱亦与活性有关。经过H_2还原后催化剂的ESR信号与O_2吸附前的一致,说明O_2吸附没有影响催化剂的结构。
