In this paper, we adopt two types of model of a three-level atom in a double-band photonic crystal described respectively by isotropic and anisotropic dispersion relations at the band edges.

在本文中，我们采用双带光子晶体中的两种三能级原子模型，它们分别由禁带边缘的各向同性和各向异性的色散关系描述。

The analysis indicates that only SWNTs with diameters larger than about 1.5 nm can be modeled as isotropic thin shell model with constant thickness and elastic moduli.

结果表明只有直径约大于1.5 nm 的单壁管，可以用常厚度、常弹性模量的各向同性超薄壳模型。

This solution has no relation with properties of the imaginary isotropic layer, and this is consistent with the uniqueness theorem of elastodynamics.

所得结果和假想层的力学性质无关，符合弹性力学问题的唯一性定理。

Here, the theory and the deducing process of the SEM based on the Legendre polynomial is given. The SEM can get a global diagonal mass matrix, which leads to a very simple explicit time difference scheme and high efficiency. Numerical simulation in the transversely isotropic medium are shown and the results approved that the SEM is a effective method for seismic wave modeling.

Magnetization curves of the polycrystalline Fe-Co and Ni-Co alloys of the cubic system and also of the pure cobalt were determined by means of a ballistic method. Gans' theory of the magnetic properties of isotropic ferromagnetics was applied. The agreement between his theory and the experimental results is quite good for the strong fields but not so for the weak fields, just as in the ease of the pure ferromagnetics.

用冲击法量属於正方晶系之铁钴及镍钴合金并纯钴之多结晶体之磁化曲线与Gans氏各向同性铁磁物质磁性之理论相较知在强磁场时理论与实验之契合甚佳在弱磁场时则较差，弱磁场时之差异，可以Gans氏计算时略去磁化各元晶体於其易磁化方向至饱和度所需之自由能一点解释之改正此点后理论与实验之契合大体改善在数种合金且极佳。

D Flexible LC notepaper:After a flexible PDCLC sample is irradiated with a suitable UV light for a suitable period at isotropic state, the CLC texture in whole sample is changed to scattered focal conic.

应用在软性基板的PDCLC元件在受到适当紫外光照射后可得一散射态之可挠式面板，若施加适当压力，可如触控笔般在元件上写入讯息或图像，该图像为反射结构。

It has been expounded and verified that AY can only be a fruitage of the process accumulation of the difference in physical elapsed-time caused by the different intrinsic-real velocity of physical clocks between the traveler and earth mainly in the two inertial phases,the Lorentz-Filtzgerald Contraction; which denies the SR's Key Gene and reveals:（1）The Absolute Reference System must objective-uniquely exist in the universe, and ①the Lorentz effect of whole universe relative to ARS all are IRPCE,②the time-space of ARS is isotropic and steady-homogeneous.

这是关于物理时空理论问题的第一个最重要的关键性奥秘！它彻底否定了KGS，揭示了"绝对参照系和相对于ARS的Lorentz-Filtzgerald效应客观存在的必然性"，表明狭义相对论是核心灵魂缺失了的片面性理论。

Present dark material research may be deduced from the continuous medium, and it is very easy in the isotropic universe to obtain the tensor the fundamental mode.

摘要当代暗物质的研究从可压缩连续介质角度给出，在均匀各向同性的宇宙中很容易得到能动张量的基本形式。

另一方面，更重要的是由于城市住房是一种异质性产品。
