In 2000, F. LUCA proved that Fermat number are anti-sociable numbers, and in 2005, M. H. LE proved all powers of 2 are anti-sociable numbers. We have used the method of M. H. LE to obtain some new results of the anti-sociable numbers. For every integer n containing prime divisors that are 1 mod 4, let p mod 4 be an arbitrary prime divisor of n. There is at least one anti-sociable number in n^2, p^2n^2, p^4n^2, and p^6n^2. Therefore we can prove that anti-sociable numbers have positive density in perfect square numbers. We also give a method to find the exact anti-sociable numbers.
LUCA证明了Fermat数都是孤立数;2005年,乐茂华教授证明了2的方幂都是孤立数,用乐茂华教授的方法给出孤立数的一些新的结果:对于任意含有4w+1型素因子的正整数n,设p为n的任意一个4w+1型素因子,则在n^2,p^2n^2,p^4n^2,p^6n^2里至少有一个是孤立数,因此可以证明孤立数在完全平方数里有正密度,另外也给出求解确定孤立数的方法。

There is no significouldt variation between the function of Method 1 and 3 in the indexes of digestive and absorptive function,except the effect on body weight and food intake;as well,model 2 shows no significouldt influence on the indexes besides body weight lose.1.4 ConclusionsContrast the three modeling methods,model 3 is the most obvious and steady method for the establishment of deficiency of spleen YANG.2 comparison on the efficacy of Lizhong Pills influenced by dried ginger and its different components on digestive and absorptive functions and energy metabolism2.1 ObjectivesThis research was designed to observed the different influences of Lizhong Pills formula on the models,which contains dried ginger or its main group of components(volatile oil and water solubles).It would be explored from two levels of material base,single herb dried ginger or its different components,to confirm that the whole effects of Lizhong Pills do mainly depend on its main herb dried ginger in the formula just as the traditional acknowledgement in TCM.Further more,the connotative meaning of dried ginger used as the main herb in Lizhong Pills egthe aspect of pharmacology and chemistry would be preliminary revealed.2.2 MethodsEach group of model rats of deficiency of spleen-YANG were to be duplicated by method 3 for 14 days,and be treated by corresponding drug samples for 8 days.
造模方法1对消化吸收相关药理指标的改变与造模方法3的影响相似,但对模型动物的体重和食量的影响不明显;造模方法2除能使模型动物的体重减轻外,对其他各指标均无显著影响。1.4结论对比实验采用的三种石膏-知母的给药方法,方法3的造模效果最为显著和稳定,即以每日灌胃给药,连续12天,恢复9天,是本实验证实的最有效的脾阳虚证候模型制备方法。2干姜及其不同有效部位对理中丸消化吸收功能及代谢的影响2.1目的通过对理中丸中君药干姜,以及干姜中挥发性成分和水溶性成分对理中丸主要功效影响的研究,从药味和化学成分群两个层次,证实君药干姜及干姜中的主要活性成分群对理中丸整体功效的决定性影响,以初步揭示理中丸中君药核心地位的药理学和化学内涵。2.2方法采用石膏-知母复合造模法制备大鼠脾阳虚证候模型,造模期为14天1;治疗期间各给药组分别给予治疗药物,连续给药8天。

A selective and mild PS-DIB/ionic-liquid immobilized 2, 2, 6, 6-tetramethyl-piperidin-4-ol-N-oxyl catalytic oxidation procedure of alcohols to the corresponding aldehydes and ketones in ionic liquid BF4 at room temperature was developed. The oxidant PS-DIB was prepared via the iodation and acetylation of polystyrene resin.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称;三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起,称之为挽歌体诗人或者史诗诗人,他们被称为诗人,似乎只是因为遵守格律写作,而非他们作品的模仿本质。
