X-ray diffraction was used to analyze the crystal structure and the field-emission scanning electron microscopy inspected the surface and cross-sectional morphology. X-ray photoelectron spectroscopy is used to determine the film composition. The optical transmittance, electric resistance, Hall Effect, and Seebeck coefficient were measured. It was found in XRD patterns that all samples possess In2O3 structure.

结果表明：足球运动员大腿肌肉横断面积大于速滑运动员，差异主要表现在股四头肌和股后肌群。

In the region upstream of vortex breakdown, the sectional streamlines emanating from the leading edge spiral inward to primary vortex and in the region downstream of the breakdown, on the other hand, the streamlines separating from the leading edge are not entrained into the vortex core in the instantaneous sense. Along the axis, the topology of the primary vortex alters several times starting from stable focus near the apex to unstable focus, and lasts back to stable focus near wake edge, the stable hmit cycle and unstable limit cycle are shown in this evolution.

发现在截面流线谱中，即使奇点的类型、数目及位置相同，奇点的连接方式也有可能不同；旋涡破裂点前，主涡由来自前缘的力线卷绕而成，主涡焦点与前缘半鞍点相连，旋涡破裂后，来自前缘的力线不再卷入主涡，主涡焦点与对称面上的鞍点相连：在流体由翼尖流向后缘的过程中，截面流线谱的拓扑结构发生了多次变化，主涡焦点相继由稳定状态转变为不稳定状态，最后又转化为稳定状态，并先后出现了稳定的极限环及不稳定极限环。

An oxygen-bubble and white-light speckle velocimetry method is presented.Instead ofpulsed laser and commonly used particle,a sheet like-bubble mass generated from anade wire byeletrolysing water is used as particle tracer,a white light flash set controlled by digital time delaycircuit is used as double pulsed light source,and 2-D velocity distribution in a sectional planewithin flow field can be obtained without using light sheet technique.

提出了一种氧气泡粒子白光散斑测速技术，与以往散斑测速方法不同的是，采用电解水时电解阳极丝上产生的氧气泡做为流场示踪粒子，用两个闪光时间间隔由数字延时电路控制的普通闪光灯做为散斑底片拍摄时的双脉冲光源，并且勿需片光技术，即可获得流场内部一个截面上的二维速度分布。
