The results showed that contents of all 15 hydrolyzable amino acids decreased with depth. The decrease of Thr, Ser, Gly, Ala, Arg, Val, Phe, Ile, Leu and THAA can be well described with a exponential equation c=c0 e-kz.

• 结果表明 ,15种水解氨基酸含量均随深度而下降 ,其中苏氨酸、丝氨酸、甘氨酸、丙氨酸、精氨酸、缬氨酸、苯丙氨酸、亮氨酸、异亮氨酸的含量以及水解氨基酸总量随深度的变化可用指数方程c=c0e -kz加以描述 ;
