查询词典 conductivities

The microstructures of composite membranes were studied by XRD and SEM. The thermal stabilities, methanol permeabilities and proton conductivities were investigated. Water uptakes and dimensional stabilities were also studied. The results indicate that amorphous zirconium phosphates are formed in the composite membrane, and have a good combination with the organic phase.

采用扫描电镜观察复合膜的断面形貌；采用热重分析仪研究复合膜的热稳定性；采用气相色谱测量并计算了复合膜的阻醇性；采用交流阻抗法测量复合膜的质子传导率；同时还研究复合膜的吸水率、尺寸稳定性。

It is found that the density of sinters is better when the temperature raise. The conductivities of sinter by addition of 5% polyethylene glycol than that of 1% polyethylene glycol.

结果表明：当烧结温度提高时，陶瓷样品的致密度提高，添加5%聚乙二醇制备的陶瓷样品的电性能比添加1%聚乙二醇制备的陶瓷样品高。

Because iron is recognized the major constitute of the Earth's core, and the Bloch-Grüneisen formula holds true in the solid-liquid mixed phase region, the electrical conductivity distribution in the Earth's core was calculated by combining with the temperature structure of the Earth's core with the PREM model. The electrical of conductivities of the Earth's core vary from 4300Ω〓cm〓 to 8400Ω〓cm〓, and increase with the pressures or depth.

既然Bloch-Grüneisen公式被证明在地核的温度、压力条件下及铁的固-液混合相区仍然有效，对于主要成分由ε-铁组成的地核，就允许用Bloch-Grüneisen公式并结合地核的温度结构以及PREM模型计算整个地核（包括液态外地核与固态内地核）的电导率分布。

In order to study water characteristics for clay soils in north and south regions, Lou soil in the north and Red soil in the south were chosen. The retention curves and saturated hydraulic conductivities were measured and infiltration experiments were conducted by double-cycle type of infiltrator.

为了研究南北方粘质土壤的水分特征，选择北方塿土和南方红壤典型粘土，测定其持水特征和饱和导水率，采用双环入渗仪进行入渗试验。

The results show that the purple soil unsaturated hydraulic diffusivity based on the redistributions of soil water both vertically and horizontally is in good agreement with the measured values and its unsaturated hydraulic conductivities determined by the same method deviate greatly from the mesured values.

结果显示，结合土壤水分垂直和水平再分布过程推求的紫色土水分扩散率与实测值具有很好的一致性，但推求的非饱和导水率偏差较大。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
