T curve of the corresponding solvate trends towards the lower temperature A linear relationship was observed between the mol. vols. of the monohalogenated benzene and the Tc values of the corresponding solvates, with the only exception being the chlorobenzene analog. This anomaly is attributed to a first-order phase transition occurred around 185 K, which coincides with the Tc value of this solvate.
特别在单卤代苯系列中,溶剂的分子体积与Tc值呈线性关系,但氯苯溶剂合物是例外:后者的反常现象主要是由晶格内部的Tc≈185K时伴随发生了与自旋变异协同的一级相变所造成,这个相变过程已为示差扫描量热测定和Mossbauer中心位移对温度的曲线呈现的不连续性所证实。

And, theoretical and experimental studies have been carried out of the performance of the heat transfer enhancement by adding a proper amount of nanoparticles to the thermosiphon with water as the working fluid. Compared with the ordinary thermosiphon, results indicate that this heat pipes posses such advantages as good startup, lower tube wall temperature, and its heat transfer coefficient is increased by 47~96%, heat flux is increased by 7.6~15% in the range of the experiment. The performance of the heat transfer relates to the diameter and the volume fraction of nanoparticle.

In the first part, it was investigated the interaction between Pb2+ and La4Ti9O24 ceramic bulk. The result shows that a significant Pb2+ diffusion into La4Ti9O24 ceramic bulk and a significant crystallization of the La2/3TiO3-type phase is clearly observed in the Pb2+ diffusion layer. The reacted zone consists of the La2/3TiO3-type phase exhibits the linear dependence of the square of the thickness, x, on the heat-treated time, t, in excellent agreement with the parabolic law x2 = kt, where k is the growth rate coefficient. The kinetic study thus indicates that the Pb2+/La4Ti9O24 interaction strictly obeys the theory of the reactive diffusion. Furthermore, the experimental k values were used to determine the associated activation energy, Ea, for the formation of La2/3TiO3-type phase using the Arrhenius plot and the following least-square equation, ln =-Ea/RT + A, where T is the annealing temperature, R is the universal gas constant, and A is a constant, resulting in Ea ~ 607 ?b 60 kJ/mol.
首先, 以巨观的方式观察PbO与La4Ti9O24陶瓷体介面的反应现象;利用X-ray绕射分析以及扫描式电子显微镜来观察不同的热处理温度以及不同的持温时间所制作的样品,研究结果发现, Pb2+离子会渗入到La4Ti9O24陶瓷内,同时在Pb2+离子所渗入的区域内会产生新的La2/3TiO3-type钙钛矿斜方晶相;藉由量测不同温度与时间之样品,其因Pb2+离子渗入而产生之La2/3TiO3-type相层厚度之关系,符合反应式扩散机制中 x2 = kt 之关系式(其中 x:扩散层厚度; k:反应速率常数; t:反应时间);进一步将不同实验条件所得到之反应速率常数值代入Arrhenius方程式ln (k =-Ea/RT + A ,其中Ea:活化能; T:绝对温度; R:气体反应常数; A:常数,可以求得Pb2+离子与La4Ti9O24陶瓷发生反应式扩散所需之活化能为607 ± 60 kJ/mol。
