A new kind of generalized energy is proposed as the lyapunov function, and thereby resulting in a new criterion of generalized nonlinear symmetric stability. it shows that not only must the dissipative coefficient be greater than a certain critical value but the initial disturbance amplitude must be synchronously smaller than another marginal value as well
從含摩擦耗散的f平面上boussinesq近似下的非線性方程組出發，提出了一種新的廣義能量作為lyapunov函數，導得了一種新的非線性對稱穩定性判據：即不僅耗散系數大於某一臨界值而且同時初始擾動振幅小於另一臨界值。 -
Therefore, it is useful to decrease nitrogen application amount or even with n application in split time so as to decrease the n loss and leaching in the paddy - field. 6. to define and calculate even productivity of nitrogen in the surface water - body ' of paddy field ( epnw ), marginal productivity of nitrogen in the surface water ( mpnw ) and elasticity coefficient of nitrogen in the surface water ( ecnw ), indicated that epnw and ecnw increased with n application amount increase, however mpnw has no the rule
6 .定義和計算水氮平均產生力、水氮邊際產生力和水氮產生力彈性系數，表明水氮平均產生力和水氮產生力彈性系數是隨著施氮量的增加而增加的，而水氮邊際產生力隨施氮量的增加並沒有表現出明顯的增加趨勢。
