In dust defying gravity a single unedited tracking shot describes the movement of a dust particle falling through the interior spaces of the Dunsink Observatory in Dublin.

在"尘埃藐视重力"中，作者用单机未编辑的拍摄描述了一粒尘埃在都柏林丹辛克天文台内部落下的旅程。

Based on the strong relationship about frames near by, the Author brought forward an particle filter algorithm importing weighted sampling about pre-frame in object tracking. The algorithm resolves the trickiness in traditional SIR algorithm which depends on statcmodcl acutely by importing proposal distribution. The algorithm can track object which movement is irregular.

根据相部帧间信息的强关联性，提出一种引入前帧加权采样的粒子滤波目标跟踪算法，解决了传统采样重要性重采样(SIR算法由于引进提议分布而需要严重依赖目标的系统状态模型的问题，可以理想跟踪运动状态不规则的目标。

The sorter can accurarely grade pearl rice,normal rice,big crushed rice and small crushed rice by their particle,special structure and plane rotary movement of the sieve,It can improve the trimness degree of the rice so that the commodity can get higher value,It is also suited to other grain mqterial.

该机利用大幅度的平面回转运动，利用整米和碎米在粒度上的差异和独特的机体结构。配备精确的冲孔筛板将白米中的特一米、一般米、大碎米、小碎米准确分离，提高白米的整齐度，创造更高的商品价值。

Numerical simulation show that RSM and VOF as well as Stokes Lagrange Model can commendably bewrite limestone particle Separation Mechanism of complicated 3D movement in Hydrocyclone.

数值模拟表明，雷诺应力湍流模型、自由表面多相流动模型和斯托克斯拉格朗日模型能很好地描述水力旋流器内复杂三维运动的石灰石颗粒分级运动和规律。

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。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。
