In this project we obtain a sufficient and necessary condition for a finite group G has a p-block with a normal p-subgroup D as a defect group, a necessary and sufficient condition for a group which is an extension of a nilpotent group by an abelian group has a p-block of defect zero.

本项目中我们给出了正规p-子群是有限群G的亏群的一个充要条件和幂零群被交换群扩张的群有亏零块的充要条件。

The present invention relates to a coating composition comprising; A at least one polyester oligomer prepared from reactants comprising a 20 60 wt.% of at least one polyol, b 5 30 wt.% of at least one polycarboxylic acid selected from the group of cyclic polycarboxylic acids, the esters or the anhydrides thereof, wherein the carboxyl groups are separated by 3 carbon atoms or less, and from the group of alpha , beta -saturated acyclic polycarboxylic acids, the esters or the anhydrides thereof, and c 20 60 wt % of at least one monocarboxylic acid, the sum of the wt.% indicated for the reactants,, and always being 100 wt.%, and the oligomer being a low-viscosity oligomer having a weight average molecular weight Mw of less than 5,000, and a hydroxyl number in the range of about 200 to about 400 mg KOH/g oligomer, and B at least one polyisocyanate.

本发明涉及一种包含如下组分的涂料组合物：A至少一种由包含如下成分的反应物制备的聚酯低聚物：a20-60wt％至少一种多元醇，b5-30wt％至少一种选自其中羧基被3个或更少碳原子隔开的环状多元羧酸、其酯或酸酐以及选自α，β-饱和的无环多元羧酸、其酯或酸酐的多元羧酸，以及c20-60wt％至少一种一元羧酸，其中反应物、和的wt％之和总是为100wt％，所述低聚物是重均分子量Mw低于5000且羟基值为约200-约400mg KOH/g低聚物的低粘度低聚物，以及B至少一种多异氰酸酯。

3M i τi = 2 a i bi 3M i k = Ga i b i3 由后一式得 Gka i b i3 Mi = 3 60 Also Gk M =∑Mi = 3 i a i bi3 ∑ So we have: M a i b i3 = M 3 ∑ a ibi i Consequently we have:τ 3 Mb i = a i b i3 ∑ 3M k = G ∑ a i b i3 It is noticeable that: the shear stress of the midpoint of the long side of the narrow rectangle is considerably precise.

而 故有 Gk M =∑Mi = 3 M i a i bi3 ∑ a i b i3 = M 3 ∑ a ibi 从而有τ i 3 Mb i = a i b i3 ∑ 3M G ∑ a i b i3 k =值得注意的是：由上述公式给出的狭矩形长边中点的剪应力已相当精确，然而，由于应力集中的存在，两个狭矩形的连接处，可能存在远大于此的局部剪应力。

Polymorphisms in FSHB gene and association with egg production traits The SSCP detection of PCR products showed that FSHβpro site was polymorphismic in two population. Six nucleotide variation at G-494A, T-470A, A-464G,-450A insertion, A-405G and A-361G,were identified in promotor region of TaiHu chicken;Three nucleotide variation at A-464G,-450A insertion, A-405G,were identified in promotor region of blue eggshell chicken,three genotype.

FSHβ基因多态性与产蛋性状关系 FSHβ基因5'调控区和外显子3经PCR-SSCP检测发现，两个鸡群在FSHβpro位点都有多态，太湖鸡发现6处碱基差异，分别是：G-494A，T-470A，A-464G，-450插入碱基A，A-405G，A-361G；而绿壳蛋鸡在该位点有3处突变，分别是A-464G，-450插入碱基A，A-405G，有3种基因型。

Results:The medians of blood lead levels of 8 836 children were 83.86 μg/L , and 2 097 children (23.73%) were found with a blood lead level≥100 μg/L.

结果：8836名儿童血铅均值为83·86μg/L。

The findings suggest that expression of HLA-G in tumors may be a wides pread phenomenon in tumor biology and this may permit tumors to escape from host immunosurveillance.

结果提示，HLA-G表达可能是肿瘤生物学中的普遍现象，生殖系统癌细胞在发生和发展过程中其基因表达有可能出现反分化现象，开始表达HLA-G，从而使癌细胞产生免疫耐受，逃逸宿主的免疫监视。

Precise measurement of the Newtonian gravitational constant G plays important roles in the fields of the gravitation, geophysics, astrophysics, and cosmology. A torsion balance with timeof-swing method to determine the gravitational constant G is proposed.

Torsion balance ；万有引力常数G的精确测量不仅对于弄清引力相互作用的性质非常重要，而且对于整个理论物理学、地球物理学、天文学和宇宙学等都具有重要意义。
