查询词典 implicit differentiation

Traditional method to coarsen and disperse the spatial data to lower administer unit in order to let spatial data be agreement to statistic data loses some spatial information. The comprehensive indexes got from these data of course cannot express the land-use spatial differentiation regularity well.

传统的研究方法是将空间数据"粗化"和"离散化"到行政单元上，与统计数据匹配，结果失去了一些指标的空间分布信息，得到的综合评价指数并不能较好地反映区域土地利用的空间分异规律。

Finally, the article concludes the characteristics and regional differentiation rules of vulnerability in the coastland and analyzes the reasons of this phenomenon, in order to find out the origin of natural disaster vulnerability from the human society and to provide effective basis for insurance and decision-making of governments.

最终，对沿海区域自然灾害脆弱性的特点进行研究，探讨了该区域宏观脆弱性的区域分异规律，并分析了产生这种现象的根本原因，旨在从人类社会本身找出灾难根源，为灾害保险和政府决策提供有效指导。

NAD+ is a known cofactor of SIRT1, which plays an important role in numerous physiological processes, including differentiation of skeletal muscle cells, and has been implicated in regulation of lifespan and aging.

已知NAD+是SIRT1 的一种辅助因子，后者在众多生理过程中扮演着一个重要的角色，包括骨骼肌细胞的分化，而且还牵扯到了寿命和衰老的调整。

In the early phase of differentiation a series of structural changes occurred at some local areas of the coleorhiza.

胚胎分化时胚根鞘的形态结构特征的变化与营养吸收相联系进行了实验观察。

Based on analyzing the d-δ commutation relation for the linear stationay differential constrained systems and affine differential constrained systems, the relationship between noncommutator of differentiation and variation and nonholonomicity of the differential constraints is briefly proved by means of Frobenius integrability theory.

文中以微分约束的Frobenius可积性理论为依据，在分析线性稳定微分约束系统和仿射微分约束系统的d-δ对易关系基础上，简要论证了微分与变分的非对易子与微分约束的非完整性之间的关系。

Comparison is an effective method for differentiation.

比较是鉴别的好方法。

Basically, for complex differentiation, we require that there be a notion of 'slope' of the complex curve w=f at any point z in the function's domain.

基本上，对于复杂的区别，我们需要有观念'倾斜'复杂曲线在功能的领域的任何点 z 的 w=f。

However, the influence of internal environment after cerebral hemorrhage on the survival and differentiation of NSCs is a complex and variable process.

然而，脑出血后局部内环境对移植神经干细胞存活分化的影响是一个复杂多变的过程。

The analysis of molecular variance revealed that 93.85% of the variance component was attributable to the variation among individuals within ditches. Low levels of the genetic differentiation coefficient among ditches, G=0.172 and Nm=2.4, indicated that the ditches barely hinder gene flow between Scaevola populations. UPGMA cluster analysis and principal coordinate analysis revealed no major groupings among ditches or among plants.

经过分子变方分析显示海南草海桐有93.85％的变方成分存在於个体间；POPGENE分析结果显示其遗传分化系数G(下标 ST为0.172，而基因流为2.4，显示沟渠并无阻碍基因交流之能力；UPGMA归群分析及主座标分析结果显示海南草海桐个体间几乎无差别或差异很小。

Technical Product differentiation includes structural design, introduction of new technology, new process improvement, quality control of component parts selection, whole system to match composite indicator, which is the basis of competition in an invincible position.

技术产品差异，包括结构设计，新技术，引进新的工艺改进，质量控制部件的选择，以配合整个系统的综合指标，这是在竞争中立于不败之地的基础。

"Second Life is remarkably easy to work with, and is very popular,"

"第二次生命是显着容易的工作，并且很受欢迎，"

For example, we usually assume that materials are homogeneous and isotropic and free of internal defects or flaws.
