Replaces the non-linearity of space and time with one kind of description equation in more profound non-linear mechanism, this new transformation being similar as Lorenz transformation, but has the more widespread covariant invariability.

实际是把时空上的非线性用一种描述方程上的更深刻的非线性机制来代替，这种新的类似于洛伦兹的变换具有更广泛的协变不变性。

In return for this restriction, the interface becomes "covariant" in T , which means that an IEnumerable is considered an IEnumerable if A has a reference conversion to B .

有了这一限制，接口对于 T 类型就是"协变的"，这意味着如果 A 可以按引用转换为 B ，则 IEnumerable 可以当作 IEnumerable 使用。

As the lexicon is the component of langauge that is most susceptible to change, this article attempts a contrasitve analysis of the neology in the Russian and Chinese lexcions with a view to discover the cultureal origin in the development of society in terms of the covariant relation of language and society.

本文就俄汉语中近年来新词产生的现象进行分析和对比，挖掘其社会发展的文化起因，来源是语言与社会的共变关系。

We find that the covariant continuity equation for the spin current plays a key role in keeping the consistency of the SU(2) Kubo formula with different gauge fixings.

我们发现，自旋流满足的协变形式连续性方程保证了SU(2)Kubo公式在两种不同规范固定下的自洽性。

In this paper well use this covariant theory to discuss the prolongation structure of the integrable the inhomogeneous equation of the reaction-diffusion type: By establishing SL(2,R)principal bundle and its associated bundle and finding both 1-dimensional realization and 2-dimensional realization of its algera ,we can successfully give its AKNS-equations and Backlund transformation.

本文就是利用这套协变的延拓结构方法讨论了可积的非其次反应扩散型方程的延拓结构。通过建立SL(2，R)主丛及其伴丛，并找到其李代数的1维和2维实现，我们成功得到了其反散射方程和Backlund变换。

We mainly investigate the influence of different covariant representations on the satisfiable extent of the Hugenholtz-Van Hove theorem in the nuclear medium in the framework of DBHF.

结果表明：不同的协变表示对核子自能各分量的动量相关性和密度依赖性均有重要影响，进而对核介质中HVH定理的满足程度产生重要影响。

The Green-Schwarz superstring theory is a covariant theory.

在具有Ramond-Ramond形式场的AdS_5⊕S~5背景中，ⅡB型超弦的作用量用Green-Schwarz描述方法最为适宜。

The introduction of local supersymmetry on worldsheet results in the Ramond-Neveu-Schwarz model, and global supersymmetry in the ten-dimensional spacetime directly yields the Green-Schwarz superstring. The Green-Schwarz superstring theory is a covariant theory.

这两种描述方式的不同点是：Ramond-Neveu-Schwarz超弦理论在超弦的世界面引入局域的超对称，Green-Schwarz超弦理论是在十维时空中直接引入超对称，它是一个协变的理论。

In this study, EPMA and LA-ICP-MS were used to determine the major and trace element concentrations, respectively, of apatites from Transhimalayan granitoids. The results indicate that F, Mn, Sr and REEs in apatites generally show good correlations with compositions of their host magmas and thus have high potential to be utilized as petrogenetic tracers. More specifically, F and Mn contents in apatites are covariant with the aluminosity of the host rocks so that can be used as an indicator for magma differentiation. Combining with Sr and REE data, which show significant variations in apatites from different rock types, these elements may be furthermore used to construct "discrimination diagrams" for more detailed investigations of complex petrogenetic processes such as magma mixing and compositional heterogeneity.

本研究中，电子微探以及雷射烧蚀感应耦合电浆质谱术分别被用以量测藏南火成岩中磷灰石的主量与微量元素含量，微区分析的结果显示，磷灰石的氟、锰、锶以及稀土元素均与岩浆源成分展现良好的对比关系，揭示了它们应用在岩石成因示踪上的优秀潜力：其中，磷灰石氟、锰含量的变化与原岩的铝饱和情形息息相关，因此可以作为岩浆分异程度的指标；而锶以及稀土元素则在不同岩石类型来源的磷灰石中展现了明显的丰度变化，因此综合这些元素将有机会进一步建立岩浆来源的「鉴别图」，甚而以此讨论岩石成因，例如：岩浆混合与源区组成的不均一性。
