The nanoplex were smaller than the unmodified nHAP; thelipiodol/nanoplex emulsion, with the mean diameter at 75±11.8nm can disperse moreuniformly and be more soluble and stable, contrary to the unmodified nHAP and nanoplex Conclusion: Nanoplex/pDNA mass ratios greater than 15 had exhibited completepDNA absorption onto positive charged polyplex and pDNA protection from thedestruction of nucleinase in rabbit serum. Unmodified nHAP may can\'t induce effectivegene delivery.PartⅡThe construction of the recombint eukaryotic expressive vector ofwild-type human p53 and RbObjective: To construct the recombint eukaryotic expressive vector of wild-type humanp53 and Rb by utilizing the theory of molecular medicine.
结果nHAP颗粒本身大小小于100nm,但由于颗粒表面本身带负电,不能包括有效地结合及保护DNA;经Ca~(2+)修饰后,颗粒可带正电,可一定程度地结合和保护DNA,但聚合物本身的中性电与带负电的细胞膜结合,而且本身的颗粒则变地容易聚集而成为很大的颗粒,也不利于细胞的吞噬;经PLL修饰后,颗粒溶解性提高,直径变小,表面带正电,电泳结果显示PLL-nHAP颗粒可包括有效地结合和保护DNA免受兔血清的破坏,而且复合物表面的正电也包括有利于与细胞膜的结合与吞噬。

On the basis of other scholoar's research, the author makes systematic、complete and throughgoing research on characteristics and predication of strata movement for the first time in this paper. The creative work makes up land space in domestic and abroad. The author's major work are as follows: 1 According Haken's synergetics view, the author researches the non—linear self —organized evolving process of refeeding, hybriding and cooperating features of internal varables of the roof movement for the first time, and makes an important conclusion that it will appear chaos at the critical state.

For strong convective weather , it classified all historical sample events into 4 weather patterns (like northwest , trough area ,west wind and southwest current), established 4 characteristic fields of 400hPa height of HLAFS , then according to the principle of the pattern match calculate and compare the real-time HLAFS forecast products-2-using the similar method inside the big and small key areas , establish forecast equation , finally gain conclusion .To duststrom weather, the historical samples were sorted into duststrom and severe duststrom types in 5 regions (they are whole area, west, central, middle-west and middle-east of Inner Mongolia ),moreover set up different sample databases about ECMWF fields (including 500hPa height, 850hPatemperature and sea-level pressure).In order to making duststrom forecast at different time level , we first filtered the real-time data by FAX data ,and then used the method of similar range degree to compare the historical data to the actual data of ECMWF .To precipitation weather ,they were divided into 2 types that suit or unsuit airplane artificial precipitation stimulation in line with their emergence time and district .The appropriate weather physical factors come from T106 were chosen to establish the artificial precipitation stimulation prediction model . In the actual application , we can get prediction result as long as use the real-time forecast data of T213 in the prediction model .
针对强对流天气将历史样本天气分为西北气流型、槽区型、西风气流型和西南气流型等4个类型,并建立其HLAFS资料400hPa四种特征场,按照模板匹配的原理,用相似分析方法在大、小两个关键区中对实时HLAFS预报产品进行计算、比较,再建立预报方程,得出结论;对沙尘暴天气将其按区域分为全区、西部、中部、中西部以及中东部5类,再按强弱分别分为强和一般2类,建立ECMWF的3个场(500hPa高度场、850hPa温度场和海平面气压场)的历史资料库,在用传真资料消空之后,用相似离度方法计算实时ECMWF资料,做出不同时次的预报;对降水天气按出现时间和区域分为适合和不适合飞机增雨作业2类,选择T106资料中恰当的气象物理量因子,用BP神经网络算法建立人工增雨降水预报模型,实际应用中将实时T213相关预报资料代入预报模型即可。

The results showed that different topping frequency (at intervals of 15 d, 30 d, 60 d, 90 d) had no evident influence on total wine loss, volatile acid content, T-SO2,F-SO2, wine colour, and wine pH values. Under constant temperature and humidity conditions, total wine loss was closely correlated with the using degree of Chinese barrel and the storage time in Chinese barrel. Volatile acid content slightly rose along with wine storage time. The content of SO2 dropped rapidly during 15 d after wine filling, but dropped tardily ever since. Wine colority rose remarkably during 15 d after wine filling, but climbed tardily ever since. Wine colority change was unstable, it changed wavily and depressed on the whole. In conclusion, it was recommended that the best topping interval was 90 d.

It puts forward the significance of this paper. It points out that, in the time period of our economic reform, there exist serious social credit crisis and ethic crises in the economic order of society, which have made much negative influence on the development of our socialist economy. Then, the paper deplores into the reasons of these problems and draws a conclusion that at the time when new economic management system is replacing the old one, the confusion of social economic order is normal because of the imperfect new economic management system. The market disorder will necessarily lead to moral landslide and social credit crisis. Thus it will bring about market fluctuation, make worse the environment of system reform, and impede the deepening our reform.
前言提出本文研究的意义,指出我国经济体制转轨时期,在社会经济秩序方面存在着严重的社会信用危机和道德危机,给社会主义市场经济的发展带来严重的不良影响,进而探索出现这些问题的原因,指出由于新旧经济管理体制的更替,新的社会经济管理体制尚未健全,社会经济秩序出现混乱是一种正常的现象,而混乱的市场秩序必然会带来道德滑坡和社会信用危机,使市场出现波动,改革环境恶化,妨碍了改革的进一步深入进行。
