The vapour and plasma ignition times of the target are got based on the equation of heat conduction and cascade model. We suppose that the plasma is ignited when 210 generations of new electrons are born in vapour generation time. The influence of temperature on the thermodynamics and optics parameters of material also have been considered in the model. The resulting theory has good agreement with the experiment and overseas report. A blade method to measure the laser spot is given in this paper with validation and error analysis. The plasma threshold of metals in atmosphere and water ambients both are diagnosed with the light deflection and piezoelectric transducer. A Q-switched pulsed Nd:YAG laser operating at infrared (1064nm), visible(532nm) and ultraviolet (355nm) wavelengths has been used. Al、Fe、Cu are used as targets and get a similar results with both method. Theoretical and experimental analyses are applied on the influence of wavelength on the threshold have been done, both of which have shown that the plasma threshold of metals decrease as the laser wavelength increases; The plasma threshold of metals are higher in water than in air and the pressure of the shock wave in water is five times higher than in air.
从热传导方程和雪崩电离机制出发,假设当电子增值2~(10)倍时,考虑了温度对材料热力学和光学参数的影响时,得到了气化和等离子体点燃的时间,利用该模型进行计算得到的结果与国内外报道及自行通过实验测得的阈值基本一致;提出了利用刀刃法测量激光光斑面积的方法,并通过实验进行了验证和误差分析;利用光偏转装置和压电换能器分别对空气和水中金属等离子体点燃阈值进行了实验诊断,激光器均为调Q—YAG激光器(波长1064nm,532nm,355nm,脉宽10ns),靶材分别为Al、Fe和Cu,两种测试方法得到的等离子体点燃阈值基本一致;本文从实验和理论计算两个方面讨论了波长对等离子体点燃阈值的影响,均得到了等离子体点燃阈值随着波长的增加而减小的结论;对空气中和水中不同环境下金属等离子体的点燃阈值进行了比较研究,得到了金属在水中的等离子体点燃阈值比空气中的大,且水中产生的冲击波的压强是空气中的5倍左右的结论。

The results show that not only the growth of C. wenyujin in lime soil is possible, but also the biomass, yield of medicinal part, the content of oil from the tuber and its medicinal components are higher than those from red soil. The C. wenyujin from lime soil quickly assumes etiolation during initial growth period. Surprisingly, the lusty leafs of C. wenyujin planted in red soil turn to pale and brown flecks occur in the leafs with the fertilization of N, P, K. It is concluded that C. wenyujin can be planted in lime soil; C.

And then, in the foundation of the overseas scholars'study, I study RP and the CRP methods for visualization the dynamics characteristic of the phase space track as well as the complexity degree algorithm of chaos time series——ApEn algorithm. Applying these two methods based on the VB program we analyze separately the data which is obtained from complex financial system model and Lorenz system, and obtain several new recurrence plots and cross recurrence plots. This provides the graph gist of determination complex intrinsic characteristic. The results establish the foundation for exact and further division of chaos time series.
