Error Pertinence Study And On-line Program Development In Laser-driven Equation Of State Experiment

The Equation of State (EOS) is a relationships' formula of different kinds of variables, which can describe the characteristics of matter under a given thermodynamic condition. The research of Equation of State has vital meaning in the development of natural science. It has various applications to many fields of statistic physics, fluid mechanics, plasma physics, nuclear fusion, basic particle physics, geophysics, astrophysics and armament design.In chapter one, a brief review of Equation of State (EOS) is presented , the research techniques of EOS and the regarded Laser driven EOS in recent years are introduced.Chapter two introduces the laser driven EOS experiments which are done on "SHENGUANG" facility and the involved research. The work which I participate in during my assiduously studying is introduced in detail, such as target testing and streak camera (streak speed and streak resolution) calibrating etc.. And series of laser driven EOS experiments and results are introduced.The last two chapters introduce my main work in the term of gaining the master degree.Chapter three introduces the uncertainty estimation of the physical parameters in the laser driven EOS impedance-matching experiment. The physical parameters' pertinence is critically analyzed. The effects of physical parameters' pertinence on the uncertainty of final metrical parameters(u_M, P_M) are achieved by the calculating of the existing experimental data. The calculating results indicate that the parameters' (c_s,λ_s ) pertinence has little effect on the uncertainty of parameter(uM) and the parameters'(D_m , u_m) pertinence has relatively big effect on the uncertainty of parameter(P_M).Chapter four introduces a set of on-line data processing program, the program can reduce the data processing random error and increase the data processingefficiency. Most important of all, using on-line processing program can process the experimental data and give the results on the spot in time. So some problem can be quickly found and resolved by alternating or optimizing experimental condition in experiment field, and the experiment success rate is increased by the guidance of the on-line program. At the same time.the reliability is proved by comparing the manual processing results with the program processing results. Further more, the program's high efficiency is illustrated by the field practice with the on-line data processing program.
