查询词典 derivative

We should consider six characteristics of core competence as heterogeneous, valuable, derivative, imperfectly imitable, path-depend and dynamic. If we classify the core competence by its differ seedtime, competence can embody three type: the base-competence, sub-competence, core competence.

从核心能力不同发展阶段将其划分为基础态、亚状态和成熟态的核心能力三种表现类型；核心能力的本质是企业特有的知识和资源，并存在于企业的组织资本和社会资本之中。

In the second part of our research, YC-1, an indazole derivative, displayed impressive selective toxicity against the human lung squamous carcinoma cell line NCI-H226 and human kidney tumor cell lines RXF-631L by a panel of 39 human cancer cell lines (JFCR39) screening. Therefore, the molecular mechanism by which YC-1 affects NCI-H226 cell growth was studied.

在本论文的第二部份中，吲唑类化合物YC-1经利用日本JFCR39癌细胞株之抗癌活性筛选后发现，YC-1对於人类肺鳞状上皮细胞癌细胞NCI-H226以及人类肾癌细胞RXF-631L具有高度的抑制选择性，於是我们选择NCI-H226细胞株做为YC-1对抗肺癌之抗癌机制探讨模式细胞。

With the guide of non-linear program theory, by using interpolative steps and inexact line search, an improved conjugate gradient method was found, by which the training rate of BP networks increases by tens or hundreds of times. Moreover, the improved method is effective to solve non-linear equations for which Newton's method does not converge owing to the problems of the quadratic derivative and inverse matrix.

通过大量的数值模拟试验发现，在非线性规划理论的指导下采用间插步骤和不精确的一维搜索技术改进的共轭梯度法，是基于梯度和共轭方向的连续搜索算法中最有效的算法，这种算法使BP网络的训练速度提高几十到几百倍，使BP网络的实际应用效果大为改善；而且这种算法对于用牛顿法由于求二阶导数和求逆矩阵等问题难于收敛的非线性方程组的求解也是很有效的。
