Based on the cloning FeSOD gene of the HZNH, the recombinant prokaryotic expression vector, PQESOa/FeSOD, was constructed and digested with restriction endonuclease BamH I and Pst I to check its construction. The PQE30a/FeSOD was then transformed into E.coli Ml5 and induced with IPTG. The high expression in vitro was obtained and analyzed on SDS-PAGE gel. The*results showed that the target proteins held a 37% portion in whole bacterial proteins and consisted of two parts, the soluble proteins and inclusion bodies. The soluble proteins in the aqueous layer, checked by means of activities of FeSOD enzymes and analyzed by means of activities of isozymogram from PAGE, demonstrated the induced expression proteins had the active nature of FeSOD enzymes.

On the basis of the conclusion above, the nonlinear weak controllable vectors can be obtained, which compose the second class of weak controllable matrix, by means of matrix transfermations of the first class of weak controllable matrix. Furthmore the second criterion of weak controllability, accessibility and strong accessibility, which is more standard, more succinct and more practical, is obtained. On the basis of the first criterion and the second criterion, several important problems about nonlinear controllability are discussed, which include 1 local controllability; 2 three classes of local controllable decomposition, separately by means of local coordinate changes in the neighborhood of a nonsingular point, a point on a singular surface or a designated point x〓 with a designated input u〓; 3 the character of controllability of the ith state variable x〓 in different controllable areas and their boundaries.

By means of Hua, filial duty is assimilated into the ceremony of ancestor worship, enabling the ceremony to bear the function of filial education; by means of cultivation, the individual gains the filial concept and behavior; the blood ties will be sustained and the unity and identification of the family members will be strengthened in the way of converting filial duty into the love, the respectfulness, the support and the worship to parents and the activities of repairing the clan temple and continuing the family tree. Finally, filial duty coming into the different forms of reading, playing and writing scripture finishes the entire society\'s integration and sustains the social stability.4. It is because the Bai People group passes on the filial duty in the principle of Cheng that the filial duty still has an effect on the individual, the family and the society.

通过"化"，孝道融入了祭祀祖先的仪式中，使该仪式具备了孝道教育的功能：通过"化"，个体获得了孝道的观念和行为；将"孝道"化为对父母的爱、敬、养、祭，以及修祠、续谱的活动中，就可以稳固血缘家庭关系，增强宗族成员彼此之间的认同、团结和凝集力；最后，孝道"化"到莲池会的诵经、洞经会的谈经和圣谕堂的写经活动中，完成了对整个社会的整合，维持了社会的稳定。4、孝道之所以仍旧在白族的个体、家庭、社会中发挥作用，是因为他们在传承孝道时，本着"诚"的原则。

Firstly, by means of the man'-free-and-overall-development theory of the Maxthium , the author analyzes the Personal Literary Creation and confirms its value and significance as follow:the first,the emergence of the Personal Literary Creation means the vanishment of the laberal alienation ,ie,the personal authors' writings are not only the make-a-living means but the spontaneous displays of the human wills;the second, the Personal Literary Creation confirms "everyone' free development is the condition of all the people's progress",the human-liberating ideals of Marxism,and realises the all-round respects and concerns of the literature to human' diversity and peculiarity. Secondly, standing at the point of the contemprory Chinese history, it is right the individually depressed history in China that makes the Personal Literary Creation as the historical nacessarity. The emergence of the Personal Liberory Creation makes up to the limitation of the traditional public and representitive writing, and makes a great progress to diversifying the multi-cultural pattern in 90's of the last century, expanding the literatural domain, and displaying the complicated human natures.

本文首先运用马克思关于人全面自由发展的理论对私人化写作进行分析和观照，肯定其存在的价值和意义：一是私人化写作的到来意味着劳动异化的消除，作家的创作活动成为生命意志的自由表现，由手段上升为目的本身二是吻合了马克思人类解放的理想"每个人的自由发展是一切人自由发展的条件"实现了文学对人的丰富性、多样性、独特性的全面关怀与尊重；其次立足于当代中国的历史语境，它的出现弥补了一直以来公共化、代言式写作独占文坛的局限，在丰富九十年代的多元文化格局，拓展文学探索和表现丰富复杂的人性深度方面是一个很大的进步。

Co-firing characteristics of corn stalk and stone coal in different proportion were investigated by thermal gravimetric analysis. The results showed that corn stalk can improve the ignition and combustion of stone coal. The agglomeration experiments on corn stalk were made in a bench-scale bubbling fluidized bed with quartz sand as bed material and stone coal ash as additive. The results indicate that stone coal ash can inhibit agglomeration of bed material particles at temperature of 900℃. Agglomerate of blends was analyzed by means of scanning electron microscopy, energy-dispersive X-ray, and the bed materials were analyzed by means of X-ray fluorescence. Analysis showed that aluminum element and iron element in stone coal ash can react with alkali compounds and eutectics with low melting point, form a covering layer with high melting point on the surface of biomass and quart sand particles, thus inhibit the forming and transfer of low melting compounds.
