The static experiment is done. In this paper, first I introduce some characteristics of the nano-fluids such as motion. The parallel laser is used to illuminate vertically the nano-particle producing dynamic speckle. The Laser speckle velocity is underlain by the fact that movement of a diffuse object illuminated by coherent light results in a random time variation of a speckle pattern observed in both the image plane and the diffraction field.

在描述了纳米流体的基本特点，以及根据布朗运动理论纳米流体的运动特性的基础上，考虑到将采用激光垂直照射纳米流体，由纳米颗粒散射的光线将互相干涉形成散斑的测试方法，从理论上推导了纳米颗粒的运动速度和散斑运动速度的关系，得到了在菲涅尔衍射区域，散斑的移动速度等于纳米粒子的移动速度的结论。

The specimen horizontally into two of the instrument, sample between the edge of the circular underpan between the minimum distance of not less than 50-mm, measurement should be gently 2 ~ 3 mm/min will activities on blank sample in order to avoid any impact, and make sure the piece and thickness measurement plane parallel.

Under the nominal power, the LED flashes; under that value the LED switches off the underpower alarm and the power absence alarm are sent towards the parallel port

在假负载下，发光二极管闪烁；在那数值之下，发光二极管切断（下功率报警和缺功率报警被送往平行断口

In handling his subjects, Zhu Wei skilfully turns a certain collective unconsciousness into a unique personal viewpoint. In his work he ingeniously interweaves his childhood dreams with real-life circumstances, constructing a virtual reality that runs parallel to life; a reality that is filled with all sorts of contradictory contrasts which dissolve unenthusiastically into harmony, and which mirrors a pain in the depths of his spirit. At the same time, the pain reflects his genuine concern for society and humanity.

朱伟在处理他的题材时，非常老练地将一种集体无意识转化成他个人的独特视角，把童年梦想和现实境遇巧妙地穿插起来，构筑了一个与生活并行的虚拟实在，里面设计了各种自相矛盾的对立，对立之中又自行化解为无奈的和谐，折射了他精神暗处的隐痛，同时，这种隐痛折射了朱伟对社会和对人性的真切关怀
