But the final average multiplicities of charged particles seem to be equal in three kinds of light q 0 jet events, which shows that our results are consistent to the predictions of QCD, i.e. the strong interaction is irrelevant to the quark flavor. 但3种轻味夸克事例的平均带电粒子多重数近似相等,这与QCD强相互作用与味道无关的预言一致。

It puts forward the design theories and examples of jet aerators employed in biologi - cal wastewater treatment. In the light of the characteristics of jet aeration, the types and the design principles of the jet aeration tank are studied. 提出了用于污水生化处理的射流曝气器的设计理论与实例,根据射流曝气的特点,研究了射流曝气池池型及其设计原理。
Moreover, from the light dynamic variation graph, the jet fluctuation due to the arc voltage behavior may be the dominant characteristic of the jet behavior. 相反,从谱线强度脉动图中可以看到,射流核的脉动是由电弧电压脉动造成的,这可能是射流核脉动的最主要原因。
Based on the principle of freezing high velocity particles, an in line Fraunhofer far field holography measurment system, which uses the ultra short pulse laser as the recording light source, is constructed. The metal micro jet is loaded by detonation. 利用超短脉冲激光作为记录光源可以在瞬间将高速运动微粒冻结的原理,建立了同轴Fraunhofer远场全息测试系统,研究了在爆轰加载下物质的微射流现象。
