求翻译：　　在层流状态中流体质点不互相的掺杂，流体作层状的运动，在这种流体状态，黏性起主要作用。是什么意思？

Mid-stream physical point in the laminar flow state mutual doping, fluid movement layered In this fluid state, the viscosity plays a major role.

Based on the values of the flow Re for three areas: laminar flow area, the transitional zone and turbulence, it only means that the transition zone may occur in this area, there is also the possibility of a laminar flow turbulence, turbulence required depends on the outside, so in general the fluid

In the laminar conditions the fluid particle not mutual doping, the fluid makes the layered movement, in this kind of fluid condition, stickiness plays the main role.

Physical fitness is not doping in laminar flow, fluid layered campaign, in which fluid, cohesive play a major role.

This is a turbulent zone;
