Zhong zhao ' s creative process is observing the outer world and experiencing his inner world in a unique and individual way to find “ the real actual essence under the surface ” and to look for “ the true meaning of a chaos world , to truly realize the world and endow it with a feeling of order ” , as an american critic bobnis said 钟照创作的过程也是在用个性化的方式观察外在世界和体察内心世界的过程，如美国一位批评家波布尼所说，以发现“表面之下真正真实的本质“ ；以寻找“一个混沌世界的真谛,真正地领悟这个世界，并赋予它以秩序感” 。
The optimized experimental conditions are determined and the densities of some elements in the mental alloy standard samples are measured . the experimental results shows that the spectral intensity of the plasma enhances significantly with the increase of the operating voltage and the power density . ( 1 ) to the steel ally sample , the emission intensities of the spectra reach to the maximum values when the laser operating voltage is 1600v and the argon pressure is 600 torr . under the same pressure , the spectral intensity of the plasma in the argon atmosphere is stronger than that in the air . when the argon pressure is 320 to rr , the signal - noise ration is about 5 times than that which the argon pressure is 700 torr , but the temperature of plasma is less about 1000k ( 1 )对于光谱标钢准样品，当激光器工作电压为1600v 、氩气压力为600乇时，谱线强度达到最大，并且在相同压强下，氩气中的等离子体与空气中的等离子体相比，其辐射强度明显增强；氩气压力为320乇时的谱线信背比约为600乇条件下的5倍，而等离子体温度却下降了近1000k ，即等离子体温度随环境气压的增大而增大；当激光束的焦斑在样品表面上下移动时，激光诱导量、等离子体的激发温度、谱线强度都呈不对称性分布，其最大值对应的焦斑位置都位于样品表面之下0 . 4mm左右。
