在实验上

The bonding energy of the mixed covalent/metallic Ti-Al bond for the Ti-terminated Al/TiB_2 interface is larger than that of the polar covalent Al-B bond with partial ionic-like feature for the B-terminated interface. Metallic bond between Al atoms forms across the Al/AlB_2 interface, which results in weaker interfacial adhesion than that for the Al/TiB_2 interface. The interfacial energy for Al/TiB_2 depends on the interfacial chemical potential.

Al熔体中仅存在TiB_2粒子，而无多余溶质Ti时，α-Al在TiB_2粒子上异质形核产生的Al/TiB_2界面能大于α-Al从Al熔体中直接形核时的液-固界面能，不满足TiB_2粒子充当α-Al有效异质形核核心的能量条件，这从理论上解释了Al熔体内仅存在TiB_2粒子时无晶粒细化效果的实验现象。

An analytic solution of kinematic model was obtained via Lie transformation group. It shows that the velocity of particles flow is maximum when x=0. Through locating the maximum particles velocity distributing line and taking the line as the origin line of x coordinates, the modified kinematic model could simulate the eccentric discharging well.

The author discussed the effect of opacity on stellar evolution and concentrated on the mechanism of triggering blue loop by using Padova stellar model. It shows that extended mixing at the bottom of the convective envelope changed the interior hydrogen profile, which triggers or suppresses blue loop. Laboratory astrophysics, which is a cross subject of astrophysics and plasma physics, combines the demand of accurate data of radiative opacity with the latest advances in high intense lasers to devise the third independent method to study the radiative opacity. On the basis of the comparison between stellar material and laser-produced plasma in terrestrial laboratory, the desirable way to study opacity in laboratory and the brief introduction to the experiments relative to opacity are given.

The research work presented in this dissertation focused on developing the scheme and techniques of OPCPA. This dissertation gives the results of the theoretical and experimental investigation on OPCPA scheme. The validation of OPCPA at high energy level was demonstrated successfully. And some important results were achieved. Several key techniques related to developing table-top ultra-intense and ultra-short OPCPA laser system were put forward, for example, the generation of femtosecond seeding pulses, the precisely temporal synchronization of the pump and signal pulses, the pulse stretching and recompression, the OPCPA process with high energy conversion efficiency and etc. Based on the integration of these key techniques, a 1.46-TW/153-fs OPCPA table-top ultra-intense and ultra-high laser system has been developed, which, to the best of our knowledge, has generated laser pulses with the shortest pulse duration and the highest peak power among the joule level OPCPA systems in the world.
