Based on the prior information obtained by qualitative inversion, the two stages inversion method was put forward. That is, the first stage is that distinguishing the high-quality element and non- high-quality element, and determining the initial iteration value of element sound velocity reasonably. The second stage is that treating differentially the constraint weights of the high-quality element and non- high-quality element, and then quantitatively inversing the final sound velocity distribution. The results of two concrete specimens indicate that the two stages inversion method can inhibit artifacts effectively and has better defect identification effect than normal one stage inversion.

在获取定性反演先验信息的基础上，提出了两阶段反演的方法：第一阶段，区分优质像元和非优质像元，合理确定像元声速的迭代初值；第二阶段，区别对待优质像元和非优质像元的约束权重，定量反演最终的速度分布。2个混凝土试件的模型试验表明，两阶段反演能有效抑制伪像，具有比常规的一阶段反演更好的缺陷识别效果。

The results show that the discharge and cooling stages of sparkjet were simulated by computational method. The instance energy input can produce the condition of high pressure and temperature in the actuator, which induce the forming of synthetic jet. With the increment of the input energy, the velocity of the synthetic jet could be increased to the supersonic state. Under the periodic energy input, the distribution of the sparkjet velocity on the nozzle is non-sinusoidal. And the discharge velocity of jet is much larger than the suction velocity of the flow from environment.

计算结果表明：采用本文的计算方法可以模拟出火花型激励器喷射、吸入的工作阶段；电火花瞬间能量的输入产生了腔体内的高温、高压环境，从而诱发合成射流的形成；当激励能量增加，激励器产生的合成射流速度增加，可达到超声速状态；周期性激励下，火花型合成喷喷口处的轴向平均速度随时间不是正弦分布，且喷射过程的最大速度要远远大于吸收过程的最大速度。

Furthermore, the factors affecting cutting qualities and efficiency and The research result included: firstly, matching of the tractor"s moving velocity and the cutting velocity, the degree of tightness of the cutter chain, the height of stubble, the opening of the cutting protector and the interval between two adjoining blades, the matching of configuration parameters of blades are the main factors affecting the cutting quality and efficiency; secondly, the cutter"s dynamically cutting of the arundo donaxl includes three stages: touching, cutting-in and cutting-off; thirdly, the movement tracks of stalks of Arundo Donaxl, which are cutted off has been acquired.

试验研究得到以下结论：(1)机组前进速度与切割速度的匹配、链条的张紧度、割茬的高低、护刃器的开合度及相邻动切割刀片的间距以及刀片结构参数的匹配是影响芦竹切割质量和切割效率的主要因素；(2)切割器对芦竹的动态切割过程包括接触、切入和切断三个显著不同的阶段，各阶段存在不同的切割特征；(3)得出了切割过程中被切断作物茎秆的运动轨迹曲线。
