The dacite cropping out at Jilusu on the northern margin of Qaidam basin has lots of adakitic features: SiO263.7%~64.3%, Al2O315.07%~15.27 %, MgO 3.47%~3.72 %, K2O/Na2O ratio is about 0.14~0.25, Y and Yb are both low: Y is 17.82×10-6~18.10×10-6, 17.96×10-6on average, and Yb is 1.47×10-6~1.55×10-6, Sr is high (527×10-6~537×10-6), HREE is depleted and Eu and Sr negative anomalies are relatively weak, but the content of MgO is higher than that of the typical adakite in the world.

We use the same sets of paramaters which have been successfully employed in the research of N-N scattering phase shifts and deuteron bound state, to study non-strangeness d* and strangeness S=-3 △Ω(S = 3,T = 3/2) dibaryons.

利用相同的参数,本文在推广的手征SU(3)夸克模型下,应用共振群方法,研究了矢量介子交换效应对非奇异双重子态d~*和奇异夸克数S=-3的ΔΩ(S=3,T=3/2)双重子态的影响。

Also in the 3-D space, we assign the 20 amino acids to 20 vertices of the dodecahedron. By the symmetry of the dodecahedron we obtain 3-D representation of 20 amino acids, and 3-D graphical representation and the corresponding numerical sequence of protein sequences. And similarity and dissimilarity analysis based on the invariants of graphs and characteristics of numerical sequences are given for nine RNA secondary structures of RNA-3 of virus. We construct sequence phylogenetic tree of a group of cytochromes C protein.

在DNA三联体密码子表示的基础上,在半复平面上给出了蛋白质序列的非退化的2-D图形表示,同时利用复向量的主要特征—模和相位,给出了蛋白质序列的一种数值刻划,进一步在3-D空间里,把20种氨基酸分别分配给正12面体的20个顶点,根据正12面体的对称性得到了20种氨基酸的3-D表示,进而得到了蛋白质序列的3-D图形表示和对应的数字序列,并利用图的不变量和数字序列的特征比较了9种动物的神经元

And extended codes of quadratic residue codes over Z〓(Definition 3. 4) also are discussed, which have good dual properties (Theorem 3. 9 and Theorem 3. 10). At last, two kinds of Gray map from Z〓 to Z〓 are defined (Definition 3. 5 and Definition 3. 6), and they are compared with each other, and we find the second Gray map is better than first by an example.

最后,以两种方式定义从Z〓到Z〓的Gray映射并相应的有两种码字的Lee重量定义(定义3.5与定义3.6),并以一实例计算比较了这两种Lee重量定义,指出第二种方式定义的Gray映射更好,因为其相应的Lee重量定义使得相应所得到的最小Lee重量更大。

It is the fact that three methionines distributed in the Hsp16.3 will begradually oxidated, in vitro, by hydrogen peroxide(H2O2). When the hsp16. 3 gene was cloned with pMV261 plasmid vector and transfected into Mycobacterium smegmatis, we found that the ability of anti-H2O2 will be decreased greatly among the strains of M. smeg. containing pMV261-hspl6. 3 while compared with the control strains of M. smeg. containing free plasmid vector. But we found that the ability of anti-H2O2 will be increased greatly among the strains of M. smeg. containing pMV261-38kDa while compared with the same control.

尽管Hsp16.3中有三个甲硫氨酸在体外能被过氧化氢(H_2O_2)逐一氧化,我们将Hsp16.3基因克隆到pMV261质粒上,并转染到耻垢分枝杆菌中发现,转染了pMV261-16.3的耻垢分枝杆菌抗过氧化氢的能力大大下降,而对照含pMV261-38kDa的耻垢分枝杆菌抗过氧化氢的能力却有明显的增强,据此,我们认为,Hsp16.3在细胞内可能不具有抗过氧化氢的能力。

The results show that: 27 compounds were identified at 600℃, and most of them were alkenes, alkanes, acids, alcohols and phenolic substances; geraniol was identified, and its relative content was 3.6, which shows that geranyl 8-methoxycoumarin-3-carboxylic acid ester can release a certain amount of geraniol at smoke temperature; geranyl 8-methoxycoumarin-3-carboxylic acid ester can improve and modify the flavor, enhance the notes of sweet aroma and bean aroma, and reduce the biting taste of cigarette smoke.

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。
