摘要
综合国内外有关文献，介绍了氮素对植物光合作用（包括光合色素、光合速率、光能利用率、光合暗反应、光呼吸等）、呼吸作用和一些代谢酶（包括硝酸还原酶、膜脂过氧化酶促防御系统）的影响。
Shortage of capital,underdeveloped financial market,rigid organization structure and irrational interior fund distribution are the main obstacles of Asset Liability Management (ALM).So,raising capital in many channels,making up intensive fund distribution channels and organization structure and regulating inter bank and treasury bills market would improve conditions of ALM implementation.
