The digital holographic interferometry is used in the dynamic and static measurements of phase variation induced by domain inversion. For the first time, to the authors' knowledge, they observe the existence of ridge-shape phase distribution adjacent to 180 degrees domain wall in congruent LiNbO3 crystal. During the domain wall motion, the phase variations are not uniform but have obvious relaxations. In the static measurement, the ridge elevation can vary linearly with the uniform electric field. The reasonable assumptions are proposed to explain these effects. (c) 2006 American Institute of Physics.

尖吻蝮蛇毒、蝮蛇毒及抗蛇毒血清能使接种S_(180)、EAC腹水癌的小鼠 明显延长存活时 间、降低接种率, 但不能完全阻止癌细胞生长。体外具有较明 显的导致癌细胞肿胀、膜破裂、核纤维化、坏死等作用。腹水酶活力测定及抗血 清初步研究结果表明, 癌细胞病变中产生的某些抗原物质可能与蛇毒中的酶和 毒蛋白相近。因此注射蛇毒后可在体内产生相关抗体, 中和癌细胞产生的毒素以 达到治疗目的。图1表6参10
