It should be a direction type of efficiency that the government assigns mandatorily. Under the condition of market economy, the income gap of having certain degree is rational ,it is effectual too; Of our country the main cruxeses of unfair distribution of social wealths are the unfair income assign terms and assigning process.vlndividual income tax has little effect in changing this, so it is unfit to put too much blame on the individual income tax law about the current situations of unfair distribution of social wealth; To regulate the income distributes is a system, and managing income unfair distribution should be arranged and develop simultaneously more measures too.

在市场经济条件下，有一定程度的收入差距是合理的，也是有效的；我国社会分配不公的主要症结所在是收入分配条件和分配过程不公平，个人所得税对此所能发挥的作用是极其有限的，因此不能将社会分配不公的现状过多地归责于个人所得税法，要求在指导思想和制度上提高公平特别是实质公平的程度；收入分配的调节是一个系统，治理收入分配不公也应当多措并举。

Flotation of the three pure sulfide minerals (named amesonite, marmatite and pyrrhppite) used different regeants, is discussed as to know how the useful part is separated from the ore. The flotation behavior of the three minerals is that in low pH value they have good buoyancy,while in high pH value they have bad buoyancy.
