The equations of two classes of 3D polynomial maps that are equivariant with respect to the rotational symmetries of either a regular tetrahedron group or a regular octahedron group are strictly given, on the basis of which the properties of the general Julia sets created by these 3D polynomial maps are discussed and proved.

从理论上分析并证明了三维多项式映射满足等变的条件，精确地给出了关于正四面体群和正八面体群具有旋转不变对称性的两类三维等变映射的具体公式，在此基础上讨论并证明了三维多项式映射的广义Julia集所具有的性质。

The developing ethics concerns the rationalities of the social development from the regularity of the social development that is from rehearing andhresulting "how develop quickly" to "how should develop", that reflects the theoretical direction and spiritual ultimate care about the human being's free and liberation.

发展伦理学，从对社会发展的规律性的关注转向对社会发展的合理性的关注，即从研究和解决"如何更快发展"转向研究和解决"应当怎样发展"的轨道上来，这也正是体现出它对人的自由解放的一种理论上的指导和精神上的终极关怀。

The condition of the minimum relative error is theoretically given. That is the place of the balance point should be chosen according to the ratio of the measured resistance Rx to the internal resistance Rg of the galvanometer in order to get the minimum relative error.

并在此基础上讨论了滑线电桥的灵敏度及其对所测电阻Rx的影响，从理论上给出了滑线电桥最小相对误差的条件：要使滑线电桥灵敏度所引起的相对误差最小，电桥平衡点的位置应按待测电阻Rx与检流计内阻Rg的比值来确定。

Therefore, experimental and theoretical study on phase behavior and relative permeability in real porous media under formation condition is very important.

实验和理论上研究真实多孔介质中、地层条件下的凝析油气体系相态以及渗流规律具有更大意义上的实际代表性，是非常重要的。

The design and development of embryonic stem-cell based CNS reparative strategies pose many challenges, both conceptual and practical.

So is a typical case of housing, extremely vividly demonstrated the consequences of artificially low prices -- as long as the local economy is a shortage of housing, property buyers queuing overnight and most people return empty-handed; Buy a lot of housing are not poor; Substantial economic application of the Housing prices in the secondary market have been re-sold, Xingjiabi commercial housing will not be higher than its neighboring; Many of housing design unreasonable even shoddy housing development professional resources are idle.

从理论上看，本文无法认同他们自称经济学家，却连价格信号的重要性都可以视而不见；从实践上看，他们口口声声为穷人说话，但他们开出的许多药方――诸如经济适用房、管制房价、加税、提高按揭利息，几乎无一例外是在给穷人帮倒忙。
