And then we bring forward a strategy of building metadata warehouse and a method founded on CWM metadata model, aiming to settle the problem which DW metadata can not be efficient utilized since they are short of unification.

并针对目前数据仓库系统共同存在的元数据缺乏统一规范，导致各种数据仓库工具之间的元数据因不统一而得不到有效利用的现状，提出基于CWM元模型的方法，构建元仓库。

The magnitude of optical electronegativity Dwglass indicates the nature of bonding in the materials.

那个 规模光学电DW的玻璃显示的性质，结合在材料。

If the optical electronegativity Dwglass is high, the materials are considered ionic in nature and if its magnitude is less, the materials are considered to be covalent in nature.

如果光 电DW的玻璃是高，材料被认为是离子的性质，如果其规模较小，材料被认为是共价键的性质。

Fresh weight, dry weight, root activity, peroxides activity and catalase activity were measured. The results showed that FW, DW, root activity, POD activity and CAT activity of Vallisneria natans L and Elodea nuttallii were improved when ammonia concentrations were less than 50mgkg^(-1) and 500mgkg^(-1), respectively.

试验结果表明，氨氮起始质量分数＜50mgkg^(-1)和＜500mgkg^(-1)时可以分别促进苦草和伊乐藻鲜物质量、干物质量和根系活力的增加，大于此范围则会抑制苦草为Vallisneria natans L和伊乐藻Elodea nuttallii的生长。

The results showed that FW, DW, root activity, POD activity and CAT activity of Vallisneria natans L and Elodea nuttallii were improved when ammonia concentrations were less than 50mg?kg^(-1) and 500mg?kg^(-1), respectively.

kg^(-1)和＜500mg？kg^(-1)时可以分别促进苦草和伊乐藻鲜物质量、干物质量和根系活力的增加，大于此范围则会抑制苦草为Vallisneria natans L和伊乐藻Elodea nuttallii的生长。

DW: Does it help that you're an ESOP company?

伟福：你们的公司有员工持股计划，这有帮助吗？

The convergence of the Euler method for stochastic differential equation dx =f x (t, x t-δ(t, r dt+g x (t, x t-δ(t, r dW with variable delay and Markovian Switching is investigated.

讨论了马尔可夫调制的随机变延迟微分方程dx=fx(t，xt-δ(t，rdt+gx(t，xt-δ(t，rdW欧拉方法的收敛性。

It was probably the most excitable moment we had during the shooting of that series of Doctor Who.

那恐怕是在拍摄那一季DW里最令人兴奋的时刻了。

objective to obtain the diffusion tensor maps of the normal human brain,and assess intrinstic properties of water diffusion in quantitative parameters for an anatomic analysis.methods maps of isotropic apparent diffusion coefficient and various anisotropic maps were calculated in60healthy adults from seven diffusion imagings by using single-shot echo-planar diffusion-weighted sequence.brain parenchyma anatomy was analyzed and adciso and various anisotropic index were measured.results （1）diffusion properties of different tissues and anatomic areas of normal adult human brain are different.diffusion in white matter is anisotropic;diffusion in gray matter is isotropic.

目的 获取正常人脑组织扩散张力性图像（diffusion densor imaging，dti），定量分析正常人脑组织水扩散的内在特性，进一步评价脑解剖结构。方法 60例健康正常人，应用单次激发epi-dw序列，计算出adciso图及各向异性图，分析脑实质不同区域的解剖结构，测量adciso（isotropic apparent diffusion coefficient）及各向异性指数。结果（1）脑内不同组织结构弥散特性不同，脑白质弥散表现为各向异性，而脑灰质弥散表现为各向同性。

Keen to find out more, we hooked up with Who's new leading lady Karen Gillan.

为了能尽早对她有更多的了解，我们连线了DW的新任女主角Karen Gillan。
