Taking the lindemann model as a sample system in which there exist chemical reactions, diffusion and heat conduction, we found the theoretical framework of linear stability analysis for a unidimensional nonhomogeneous two-variable system with one end subject to Dirichlet conditions, while the other end no-flux conditions. Furthermore, the conditions for the emergence of temperature waves are found out by the linear stability analysis and verified by a diagram for successive steps of evolution of spatial profile of temperature during a period that is plotted by numerical simulations on a computer. Without doubt, these results are in favor of the heat balance in chemical reactor designs.

To better understand how severe storms form and evolve in the outer rainbands of typhoons, in this study, we in- vestigate the evolutionary characteristics and possible formation mechanisms for severe storms in the rainbands of Typhoon Mujigae, which occurred during 2-5 October 2015, based on the NCEP-NCAR reanalysis data, conventional observations, and Doppler radar data. For the rainbands far from the inner core （eye and eyewall） of Mujigae （dis- tance of approximately 70-800 kin）, wind speed first increased with the radius expanding from the inner core, and then decreased as the radius continued to expand. The Rankine Vortex Model was used to explore such variations in wind speed. The areas of strong stormy rainbands were mainly located in the northeast quadrant of Mujigae, and overlapped with the areas of high winds within approximately 300-550 km away from the inner core, where the strong winds were conducive to the development of strong storms. A severe convective cell in the rainbands de- veloped into waterspout at approximately 500 km to the northeast of the inner core, when Mujigae was strengthening before it made landfall. Two severe convective cells in the rainbands developed into two tornadoes at approximately 350 km to the northeast of the inner core after Mujigae made landfall. The radar echo bands enhanced to 60 dBZ when mesocyclones occurred in the rainbands and induced tornadoes. The radar echoes gradually weakened after the mesocyclones weakened. The tops of parent clouds of the mesocyclones elevated at first, and then suddenly dropped about 20 min before the tornadoes appeared. Thereby, the cloud top variation has the potential to be used as an early warning of tornado occurrence.

Through comparison, this paper finds out that William Shakespeare （1564-1616）, the most popular and wide respected writer in all English literatures and a great dramatist and humanist in the English Renaissance perio ly d, coincides in speaking highly of love, loyalty, intelligence, harmony, integrity, righteousness, friendship, and so on with Chinese Confucian values--the most precious treasure of Chinese traditional culture reflected in the Three Cardinal Guides and the Five Constant Virtues used by Chinese people in maintaining the stability and harmony of the whole nation and society--through vivid interpretation of human ethical relations in many of his works. At present, the world comparative literature studies have entered the third stage in the circumstance of globalization and internationalization, this finding is with paramount significance in construction of the mechanism of mutual recognition, mutual justification, mutual supplementation and mutual appreciation of heterogeneous cultures. This study, taking The Winter＇s Tale （1623） as a case, is about universality, unity, and shared values of the Confucianism and Shakespeare＇s plays in the perspective of the coexistence of multiple cultures. This paper is with four parts：（1） mechanism of mutual understanding, mutual justification, mutual supplementation, and mutual appreciation introduced in the first part; （2） the Confucian values addressed in details in the second part; （3） the third part is a case study; and （4） the last part shows how the Chinese and Western literatures and cultures can be understood, assisted, communicated, and appreciated with each other by the way of comparing the great works of Shakespeare and the Confucian values featured with universalism to a certain extent

Al2O3-SiC-C castables for iron trough with fused magnesia powder （0, 3%, 6%, 9% and 12%） were prepared with brown fused corundum particles （5-3mm, 3-1mm, ≤1mm）, white fused corundum powder （≤0.088mm）, SiC particle （≤1mm） and powder （ ≤0.088mm）, fused magnesia powder （ ≤0. 088mm）, reactive α-Al2O3 micropowder, ultrafine SiO2 , Si powder and sphere pitch as main starting materials and calcium aluminate cement as binder. The specimens were fired at 1100℃ and 1450℃ for 3 h after vibrating moulding, curing, demoulding and drying at 110℃ for 24 h. Bulk density, apparent porosity, linear change rate, modulus of rupture, resistance to blast furnace slag, oxidation resistance, phase composition and microstructure of the specimens were analyzed. The results show that：（1） With fused magnesia addition increasing, apparent porosity increases, while bulk density, modulus of rupture and oxidation resistance decline, slag resistance varies slightly; （2） The main crystal phases in the specimens fired at 1450℃ for 3 h are 3C-SiC, 6H-SiC, corundum, periclase, reaction-synthesized spinel and mullite; the quantity of the formed spinel and mullite increases with the increase of fuzed magnesite addition; （3） Along the corroded side, spinel layer with about 80μm thickness forms at the co- rundum particles boundary.
