BMI-1(B-cell-specific Moloney murine leukemia virus integration site 1), a Polycomb group repressor, is always present as a PcG complex combined with RING1, HPC2, Mph2, et al. BMI-1 prolongs cells'capacity to proliferate and represses their senescence by repressing the transcription of CDKN2A through acetylhydrolasing or deacetylhydrolasing the Polycomb response elements in chromosome.

BMI-1 (B-cell-specific Moloney murine leukemia virus integration site 1)属于PcG家族，它与该家族其他成员如RING1，HPC2，Mph2等结合形成蛋白复合体，作用于染色质PREs位点，通过对组蛋白进行乙酰化和去乙酰化修饰，从而稳定抑制CDKN2A转录，最终促进细胞的增殖并抑制细胞凋亡。

Calculation of loss and gain of components in parentage and altered rocks during metasomatism, reveals that, in rubification and afforestation belts, the components brought in were K〓, CO〓, H〓O, and the components brought out were SiO〓, Ca〓 and Na〓, implying that the early ore-bearing hydrothermal fluids were rich in CO〓 and H〓O. SiO〓 brought out from potassic and chlorite alteration zones could serve as the main source for SiO〓 necessary in the formation of quartz veins, of silicification and of bericitization at shallow depth.

说明早期成矿流体为富含CO〓、H〓O等的碱性流体，其中钾化、绿化带中带出的SiO〓等是浅部石英脉、硅化、绢英岩化中硅质的主要来源，带出的Ca〓与成矿流体中的CO〓结合形成碳酸盐化，带出的Na〓则在浅部形成钠长石脉。

Technique development, basic facilities improvement and cost decline make "globalization" communication possible. 4. Globalization of communication technique aggravates the "unfairness" of international communication and leads to its different layers, classes and unbalanced distribution. 5. The end of "cold war" deconstructs the opposite between the East and the West, but not ends the difference between the South and the North and the "civilization conflict". 6. The population redistribution makes the traditional nations and countries in the relevant areas unstable and influences the original national cultural identity. 7."Globalization" communication deepens the alertness of national elite intellectuals, which makes them strengthen their sense of mission to keep and guard the spiritual home of national traditional culture (including traditional belief, value, cultural pattern and so on) that will be possibly subverted and maliciously remade. 8. The combination of "direction" and "strategy", or the speciousness makes big trans-national media corporations sweep away all obstacles and occupy the markets in the developing countries, in which have appeared the phenomenon of "narrations of traditional cultures tending to similarities". 9."Global village": myth or reality? 10. The difference of culture and ideology often causes the different understanding and value judgement to the contents of trans-national communication.

第一部分将中国国家电视文化安全问题放到"全球化"的大背景中加以考量，分别从以下18个维度展开论述：1、全球化语境与我们的抉择；2、与"全球化"同样历史悠久的"国际传播"；3、技术的进步和相关基础设施的广泛建立并不断完善以及使用成本的持续下降，使得"全球化"传播成了可能；4、传播技术的全球化，加剧了国际传播的"不平等"，导致了国际传播的层级性和不均衡分布；5、"冷战"的终结解构了东西对立，但却并未终结南北差异和"文明的冲突"；6、人口的重新分布使得相关区域的传统意义上的民族国家面临潜在的不稳定，并有可能影响到原来各个国家已经定型的民族文化认同；7、"全球化"传播加深了民族国家精英知识分子的戒心，"守望民族传统文化的精神家园"的使命感使得他们开始关注核心的"传统文化"（具体包括传统的信仰、价值观、文化模式等）的有可能被颠覆或被恶意改造；8、"方向"与"策略"的有机结合，使得大型跨国传媒公司所向披靡，在发展中国家屡屡得手，很多国家出现了"祖母的同质化"现象；9、"地球村"：神话还是现实？

This paper gave the detailed reviews on previousresearch results on subdrainage home and abroad,studied the effect and mecha-nism of subdrainage facilities on drainage,waterlogging reduction,salt removeas well as nitrogen fertilizer application under subdrainage conditions by use oflysimeter experiments and field trials.Numerical modelling on water movementin heterogeneons multilayered soils as well as the optimization layout of spacingsand depths of PVC subdrain was also investigated in this paper by numerical sim-ulations.
