激光辐射鸡种蛋的生物物理学研究

BIO-PHYSICAL STUDY ON EGGS IRRADIATED BY LASER

不同剂量的Ｈｅ—Ｎｅ激光辐射孵前种蛋胚区，对种蛋孵化、幼雏存活和生长发育等方面，可产生不同的影响．试验结果表明，激光辐射剂量低于或等于１２７４ｍｗ／ｃｍ２×１’处理时，可降低死胚率，提高孵化率，促进幼雏生长发育，增强抗病能力；高于此剂量处理时，则产生不良的生物学效应．作者从生物物理学观点，提出了激光使鸡胚激活到较佳发育态的理论，对试验结果进行了合理的理论解释．

Different amount of laser irradiation to the breeding eggs embryonic area brings different effects in the growth and development of the embryoes and their chichens. Laser irradiation a mount≤1274mW /cm2 X1 may increase the hatching rate and the survival rate of chckens, and promote the chickens' growth and development; but that > 1274mW /cm2X1,with the irradiation amount growing, give the opposite results. We provide a new BioPhysical explanation to the experimental results.
