Huge of trade the surplus will make trade friction noodles enlargement, rub the strength aggravate, our country peace rising of international environments will become be getting more rigorous.

巨大的贸易顺差会使贸易摩擦面加大、摩擦力度加重，我国和平崛起的国际环境将变得更加严峻。

printed on thin paper, swayig press paper wheel pressure weaker have enough friction queriessent paper, the 400 g/m2 thick paper is not enough, however, friction will slip of paper, so as to produce.

末了得不入结论：印薄纸时，摆不静压纸轮不弛辛不沉一不背也有不足的摩擦辛送不入纸弛，而印400g/m2的厚纸时，摩擦辛不敷，纸弛不离会滑移，从而爆发迟滞本体。

Reasons:(1) If metal friction sound is the turbocharger rotor-bearing or thrust bearing wear too much, turbocharger impeller and shell friction generated.

原因： （1）如有金属摩擦声，是增压器转子轴承或止推轴承磨损过多，叶轮与增压器壳摩擦而产生。

Copper-base sprayed welding alloy is produced by adding B, Si, Ni, Mn, Al, Fe and P into the copper base, which has sound heat conduction or electricity conduction performance, being antirust, with low frictional coefficient and sound adhesive friction wear resistance, easy for cutting and being smooth.
