1. Language and the society are covariant.

2. The covariant equation of plane motion body in curved space - time is studied.

3. Based on the increment of diversity and covariant discriminant function, the protein subnuclear location was predicted by using of the amino acid compositions and N-terminal dipeptide compositions.

4. Every vector can be resolved into covariant or into contravariant components.

5. A three - dimensional Langevin equation with covariant form is applied to describe the asymmetric nuclear fission.

6. Using subscript comma and subscript semicolon notation a standard space-time derivative is written whilst a covariant derivative is written.

7. Strong topology on function space can be better understood as analyzed from either covariant or contravariant point of view.

8. In the end of last century, based on the fixed sol-fa, 35 covariant sol-fa, which includes up, down,() re-up and weight down were designed by Chinese music theorists.

9. This decomposition may give another definition of high order tensor's covariant derivative.

10. Using the background field method, find the one-loop divergence counter term of quantum gravity coupling scalar field in the framework of covariant quantization.

11. In this paper, we prove some isomorphism theorems of dual module of integrable U -module E, and functor D is a right covariant functor.
