查询词典 determinant

Pike protein consists of S1 and S2 subunit. S1 is head and S2 is rod-shape part, intermolecular effort can bind each other. S1 can bind with host cell epimembranal acceptor. S2 can fix integral Spike protein on the cellular membrane and mediate cell-fusion with virus and host cell. There are significant antigen determinant of virus in Spike protein, genic heterogenesis can effect viral pathogenicity. SARS-CoV Spike protein, which has 23 pieces larvaceous glycosylation sit, consists of 1256 amino acid. Its N-terminals and C-terminals is corresponding conservative.

蛋白是I型膜糖蛋白，介导病毒与宿主细胞膜上的受体结合并与宿主细胞膜相融合。S蛋白由S1和S2两个亚基组成。S1形成球状部分，S2形成棒状部分，两者之间通过分子间的作用力相互结合。S1能与宿主细胞上的受体结合，S2可把整个S蛋白固定在细胞膜上，并介导病毒包膜与宿主细胞膜融合。S蛋白上有重要的病毒抗原决定簇，S基因的突变会影响病毒的致病性。

The vertical cooperation and the horizontal competition relations is an important determinant of firms clustering.

The analysis of hydrogen-producing nature was presented through the point of catalysis of hydrogenase, the production of energy and its transportation. From author's view, the course of de-hydrogen from pyruvic acid to acetyl-CoA was the chief determinant for hydrogen producing. And the balance and adjustment of NADH/NAD〓 was just the necessary condition, not the foundation reason.

本文从产氢反应的催化体系、能量产生和传递等不同角度对产氢本质进行了系统的理论分析，认为产氢发酵的第一判定条件（即产氢发酵的充分必要条件）是丙酮酸-乙酰CoA脱氢过程；而NADH／NAD〓的平衡调节机制只是必要条件，不是产氢发酵的根本动力。

When the actuated joint was rotary actuation, kinematic Jacobian matrix of the manipulator was a diagonal matrix. So it was an uncoupled mechanism. As the actuated joint was linear one, Jacobian matrix of the manipulator was an identity 3×3 matrix and its determinant was equal to one. Manipulator, therefore, was singularity-free fully-isotropic throughout the entire workspace.

当以转动输入为主驱动时，运动雅可比矩阵为3×3阶对角阵，故机构为无耦合并联机构；当以移动为主驱动时，雅可比矩阵为3×3阶单位阵，且其行列式的值为1，所以在整个工作空间内机构表现为无奇异完全各向同性。

Is this paper, a new estimate index of network reliability is introduced and an incidence matrix is used to depict the connectivity of the network nodes in a dynamic network model. A determinant arithmetic of the network connectivity and a calculate method are presented to achieve reliavility evaluation for Ad hoc network.

该文通过构建随时间变化的表征网络节点连通性状态的关联矩阵，在节点故障和移动性变化的情况下，对自组网网络可靠性进行了研究，提供了一种自组网可靠性定量评价方法。
