查询词典 matrices

IntroductionSmooth surfaced endoplasmic reticula contain plenty of cyto-chromes, which are mainly cytochrome P450 ( CYP450 ) and b5 and are very important in the process of the biotransformation of exogenetical fat - soluble compounds and the metabolism of some endogenetical matrices, such as bile acid forming^ bile pigment metabolism and steroid synthesis.

CYP450是50年代中期Williams和Klingeberg发现、60年代初木村和佐藤验证的一类b族细胞色素，由于还原型细胞色素与一氧化碳结合后在光谱的450nm处具有最高吸收峰，因而命名为CYP450以别与其它b族细胞色素，P是英文Peak的缩写。

Secondly, we discuss the semiconvergence of the block AOR method for solving singular linear systems with p-cyclic matrices.

其次，我们研究了求解系数矩阵为奇异p-循环矩阵的线性方程组的块加速超松弛迭代法的半收敛性。

Stage multisplitting symmetric positive semidefinite matrices is obtained.

Experiments were performed using polypeptide as analyte and 2,5-dihydroxybenzoic acid and sinapic acid as matrices.

以2，5-二羟基苯甲酸和芥子酸为基质，对多肽生物样品进行了实验研究。

CNTs were first pre-treated using acid solution (HNO3) to obtain CNTs functionalized with carboxylic groups. Subsequently, the stearyl alcohol was grafted onto CNT with the assistance of dehydrating agent, N,N'-dicyclohexyl-carbodiimide. Excellent dispersion in organic solvents such as acetone, THF, and chloroform was found for the modified CNTs (CNT-C18). In addition, the PBS/CNTs nanocomposites were then prepared through simple melt-blending. Mechanical properties, thermal behavior, conductivity of resultant polymer/CNT composites were investigated. The results show that excellent dispersion of nanotubes in the PBS matrices was achieved.

为了增加多壁奈米碳管在复合材料中的分散性，将碳管表面进行化学修饰，首先将多壁奈米碳管浸入HNO3溶液中，进行酸化，使碳管表面带有羧酸的官能基，然后再加入十八烷醇，在温和的条件下，藉由N，N'-二环己基碳二亚胺(N，N'-dicyclohexyl- carbodiimide，DCC)脱水剂脱水，使碳管和十八烷醇之间产生酯基的化学键结，改质后的碳管可以分散在acetone、THF、chloroform…等有机溶剂中，结果显示成功的利用DCC脱水剂完成碳管的改质。

The deep parts of the subchondral defects were largely replaced by new bone with a concomitant degradation of the matrices.

软骨下的深层部分的缺损被大量的新生骨替代，并伴随基质的降解。

This paper shows that the coupling coefficients for ideal modes, for local modes and for superlocal modes are all related by similar matrices in the sense of Lowey, and as far as discrete modes are concerned, the "equivalence"expressions derived by Marcuse are special cases of our general results.

本文将阐明：理想模式的耦合系数、本地模式的耦合系数以及超本地模式的耦合系数，三者之间通过在Lowey意义下的相似矩阵而发生联系；就离散模式而言，Marcuse导出的&等效&关系式，可以作为特例从我们得到过的结果直接推导出来。

The normal method was through the hydrolysis and poly-condensation process of tetravalent metal alkoxides and inside which rare earth dopants are simply performed by dissolving salts into initial sol, thus makes matrices being introduced a higher percent of hydroxyl groups, affects the resulting luminescence efficiency and balance of two phases.

普通的方法为将稀土盐导入金属烷氧基化合物的溶胶然后水解缩聚，这使得金属离子分离的最小化过程受限以及含羟基过多，极大影响了发射效率和两相均衡。

In this method the initial values of perspective projective matrix; rotative matrix and translative matrix are calculated from the fundamental matrix, than these matrices are optimized based on the coordinate value of corresponding points.

该方法从基本矩阵计算初始透视投影、旋转和竖直平移变换矩阵，然后以对应点坐标为基础对这些变换矩阵进行优化计算，从而有效地避免了优化计算的局部最小值，而且不过分依赖基本矩阵的计算精度。
