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。

The recoveries for 2,3-BD and acetoin were 91%and 92%,respectively.Aqueous two-phase extraction of 2,3-BD from real fermentation broth,the removal ratio of cells was above 99%,and the soluble proteins were about 85%in the top phase,which resulted in easy recovery of 2,3-BD from the top phase by vaporization because a viscous slurry was not formed by glucose,cells and soluble proteins at high temperature as in traditional separation methods.In addition,the cells recovered from the fermentation broth could be used as inoculum for further fermentation.

ABSTRACT The ionic strength of mobile phase can significantly affect the peak shape of ionogenic compounds such as antibiotics in reversedphase high performance liquid chromatography. The influence may be attributed to overloading of ionogenic analytes in lower ionic strength mobile phase. In such phase, peak becomes increasingly rightangled triangle in shape with increasing sample load together with increasing peak width and tailing.

在反相高效液相色谱过程中，流动相的离子强度可显著影响可解离的化合物如抗生素的色谱峰形，原因在于流动相的离子强度较低时，色谱填料的固定相易于过载，使离子化的化合物的色谱峰形呈典型的过载特征――峰形接近直角三角形。

The Bengtsson-Jacobson conjecture that "degenerate phase boundaries are always null" is studied by the mapping language in Chapter 4. By distinguishing a "phase boundary" from its image in the "covariant approach", the nulless of the image is proved. Time-like and null hypersurfaces in the degenerate space-times in the Ashtekar theory are denned, and then the phase boundary obtained by the "covariant approach" is shown to be always null.
