摘　　要：介绍了极化气体内靶和实现氢原子极化的实验方法;描述了氢原子的核极化度的测量方法和过程。为测出氢原子(包括复合成的极化氢分子)的总极化度,分别测量了氢原子的核极化度及与极化氢分子和不极化氢分子相关的量。测量期间的氢原子的核极化度测量结果为PΥ=0.853±0.036。We present an introduction to internal polarized gaseous targets, polarization method, polarization measurement method and procedure. To get the total nuclear polarization of hydrogen atoms(including the polarization of the recombined hydrogen molecules) in the target cell, we have measured the parameters relating to atomic polarization and polarized hydrogen atoms and molecules. The total polarization of the target during our measurement is Pr=0.853 ± 0.036.
