Dielectric cylinders of unknown permittivities are buried in one space and scatter a group of unrelated waves incident from another space where the scattered field is recorded.

设一未知的不均匀双轴性介质复杂物体掩埋在其中一空间中(不论是在半空间或三层空间中)，吾人可在另外的空间中适当的安排一组具有不同入射和极化方向的无关联波照射物体并量测在此之散射场，利用简单的矩阵运算，我们就可以克服非线性和不良情况的发生的困扰，进而重建双轴性复杂物体的介电常数分布。

The article considers that the magnetic material layer of MPCs is bismuth-substituted yttrium iron garnet which is ferromagnetic material, and the isotropic material layers are GGG, GaAs, SiO2, etc. Those materials have different relative permittivities.

Different materials like solid wood, cross-laminated veneer and less-expensive veneered constant-density boards are used to render the ceiling fan blades a smart and contemporary looks.

不同的材料，如实木、跨层单板及不太昂贵单板贴常数密度议会是用来使吊扇叶片聪明和当代眼光。

It was shown by further research that the formed tungsten oxide had an obvious layer-like structure, where from outer to inner layer the valence of tungsten increased and the reduction degree decreased. The carbonization of W depended on the replacement of W atom at the center of the body-centered cubic by C atom and the minor adjustment of C atom position and the lattice parameters.

深入研究表明，氧化钨碳还原颗粒具有明显的层状结构，自外到内钨的化合价递增，还原程度降低；钨的碳化是碳原子替换体心立方钨晶胞的中心钨原子，然后碳原子转换到钨原子点阵间隙再经晶胞常数微调而形成。

In this study, we demonstrate a programmable-erasable MIS capacitor with a single high-k Hf3N2O5 dielectric layer for many applications such as volatile DRAM and non-volatile MONOS type memories.

本文将探讨使用高介电常数氮氧化铪为介电层的可写入抹除金属-绝缘层-矽结构电容，其可应用在记忆体上例如：动态随取记忆体与快闪记忆体。

It was observed that the background of internal friction for some weak adhesives, e. g., phenyl salicylate, water glass mixture, etc. seems to be neither negligible nor constant value which is dependent on such factors as their temperature, thermal stress, time, dryness and strain amplitude, similar to that of dislocation damping.

对于水杨酸苯酯，水玻璃混合剂之类弱粘结剂所造成的背景内耗既不能忽略也不是常数，它与粘结层温度、热应力、时间、干燥程度和应变振幅等因素有关。

Results According to the single spot in TLC,five compounds were isolated from the buds of Lonicera ruprechtiana Regel.,and their structures were identifited through physico-chemical constants and spectroscopic analysis.

结果：根据在薄层色谱中呈现单一斑点结果，从长白忍冬花蕾中分离得到5个化合物，经理化常数测定及光谱学数据分析鉴定其化学结构。

Three typical micro-mechanical models for the elastic constants analysis of stitched composites are compared by calculating,wihch are in-plane fiber bend model,sine waviness model and polynomially described fiber waviness model.

通过计算对比了铺层纤维面内弯折、正弦波状弯曲、多项式描述纤维弯曲三个典型的缝合复合材料弹性常数的细观力学分析模型。

The samples from the CallovianOxfordian carbonate reef limestone reservoirs in the Amu Darya Right Bank Block are selected to test rock physical parameters by using the MTS system. Samples saturated with gas and water are tested separately under the same experimental conditions. The test results show that seismic responses are significantly different from samples saturated with different fluids. Further analysis shows that the Lame constant parameter is relatively sensitive to gas.

根据土库曼斯坦阿姆河右岸区块油气勘探需要，选取该区卡洛夫-牛津阶碳酸盐岩生物礁储层的石灰岩样品，利用MTS系统进行了岩石物理参数实验测试，通过相同测试条件下饱气和饱水岩样的测试分析，发现岩样含不同流体时地震响应特征有着明显的差异；进一步的分析结果表明：拉梅常数等参数对含气性较为敏感。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.

万寿菊对土壤要求不严，以肥沃。排水良好的砂质壤土为好。

He unstepped the mast and furled the sail and tied it.

他拔下桅杆，把帆卷起，系住。
