Theorem 7 Let G be a group, if every subgroup of G of prime order is contained in Z_∞,2 ∈π, every cyclic subgroup of G of order 4 is π-supplemented in G,then G will be nilpotent.

定理7设G是群，G的素数阶子群包含在Z_∞中，2∈π，如果G的每个4阶循环子群在G中π-可补，则G为幂零群。

A subgroup H of G is said to be π-quasinormally embedded in G, if for each prime divisor p of the order of H, a Sylow p-subgroup of H is also a Sylow p-subgroup of some π-quasinormal subgroup of G.

设G是有限群，称G的子群H在G中π-拟正规嵌入，如果对于{H}的每个素因子p， H的Sylow p-子群也是G的某个π-拟正规子群的Sylow p-子群。

With the help of its structure, this paper points out that the non-commutative finite solvable subsimple group will necessarily be a qualitative element group. And referring to the nature of qualitative element group, it can be easily identified the conditions that the ordered prime divisors in a solvable initial finite subsimple group should meet. Suppose that G is always a finite group.

利用其结构，指出了非交换可解有限次单群必为质元群，从而利用质元群的性质，可以很容易地初步确定了可解有限次单群的阶中素因子之间所必须满足的条件，主要得到下面的一些结论：定理1 G是非交换的可解有限次单群，则G′是G的唯一的非平凡正规子群，并且G′是初等交换p -群，此时| G |= p~n q，|G′|=p~n，。

Results When the culture medium was supplemented with 0 .05μg/ml sodium selenite,the proliferation of transformed cells was significant ly promoted and the transformation did not change remarkably,when supplemented w ith 0.25μg/ml,the proliferation was promoted but the transformation was inh ibited,and when with 0.75μg/ml and 1.50μg/ml,the proliferation was not pro moted and the transformation was strongly inhibited.Big dose of (1.50μg/ml) sodium selenite m ade the nuclei of the untransformed lymphocytes gather together like a few grape s doing,and even caused them to fuse.

结果 在培养物中添加0.05μg/ml亚硒酸钠能显著促进转化细胞增殖；添加0.25μg/ml可促进转化细胞增殖，但显著抑制细胞转化；添加0.75μg/ml和1.50μg/ml，不仅不能促进细胞增殖，而且强烈抑制细胞转化。1.50μg/ml剂量的亚硒酸钠使非转化淋巴细胞发生葡萄状聚集甚至核融合。

The mutagen mechanism is presumed single factor dominant.(4)There was 85 percent transvertion in mutagen spectra, and they were all G:C→T:A transvertion. The maximal possibility of mutagen mechanism is analyzed as followed:ion beam implant → breakage cell surface and enter the interior → stimulate plentiful radical born → radical oxidize and damnify DNA → G becomes 8—oxoG → 8—oxoG pairing A → result in G:C→T:A transvertion(5)Production of transition was presumed that ion beam implantion damnified DNA, stimulate activity of MMR interveniented by methyl reducing.

诱发突变谱中碱基颠换比例是0.85，且是全部G：C→T：A颠换，推测低能离子束诱变鼠伤寒沙门氏菌得分子机制可能为：离子注入→通过破坏细胞表面进入内部→刺激产生大量自由基→自由基氧化损伤DNA→G变成8氧—7，8—二氢鸟嘌呤(8—oxoG)→8—oxoG与A配对→导致G：C→T：A颠换。

Mean daily consumption of alcohol per day was greater in men than in women (28.2 25.0 g vs 13.9 15.0 g), as reflected in both in the lowest (mean, 4.1 g vs 1.1 g) and highest (mean, 68.7 g vs 38.8 g) quintiles of daily consumption. More than 50% of women consumed less than 10 g a day of alcohol, and more women were abstainers than men (3.0% vs 2.1%).

男性的平均酒精日摄取量要比女性高28.2 ( 25.0 g vs 13.9 ( 15.0 g)；最低(平均， 4.1g vs 1.1g)及最高(平均， 68.7g vs 38.8g)的日摄取量也是男性高於女性，超过10%的女性，日摄取量低於10 g；对酒精节制的女性人数也高於男性(3.0% vs 2.1%)。

The excitation and emission wavelengths in the measurement are 345 nm, 430nm respectively. When the concentrations of FWAs are from 0 to 1.0 μg/mL, they have a linear relationship with the emitted fluorescence intensity. In this interval, the calibration curve is y=0.001 7x-0.018 7, and R2 is 0.999 2, the limits of detection and quantification are 4 μg/g and 10 μg/g respectively, and the average percentage of recovery is 95.3%, which meet the measuring requirements.
