The main pollutants, for example, heavy metal inorganic salts, organic chlorine and organic phosphorus compouds, petroleum, and radioactive substance in the ocean are reviewd in this paper. The effects of these chemical pollutants on the ocean ecology and their harms to humanbeing are discussed.

In this paper, the microdistinguishability of electron was discussed by means of analyzing space orientation of electron spin magnetic moment (or magnetic pole). There are 8 kinds of spin configurations within the two electrons. Among them 4 kinds of coupling configurations, are attrative in their spin magnetic poles, and 4 kinds of no-coupling configurations are mutual repulsive in their spin magnetic poles. There are 4 kinds of coupling configurations in spin-orbital movement of electrons. There must be 8 electrons in outmostorbitals of atoms for complete coupling of magnetic poles of spin and orbital, hence, the element periodic law shows a octet rule. Magnetic moment coupling including spin and orbital is essence for chemical bonding and then the attraction of different nuclei. The generalized express language of chemical bond: the chemical bond can only consist of magnetic moment coupling electrons. Wave-particle dualism and the uncertainty principle of electron can be explained by new theory, and their physical model is consistent with the distinguishability nature of electrons.

There is a fundamental reason leading to the birth of the fuzzy conception in the process of studying of secondary school students, and the factors influencing the change of the fuzzy conception have mainly five dimensions. The weighted value of the five dimensions can be obtained through AHP, the results of which are: 0.21 for cognitive style; 0.18 for meta-cognition; 0.22 for epistemology; 0.13 for social environment/motivation/emotion; 0.26 for ontology, respectively.
