要跟上她的思路並非易事，因為她老是突然扯到題外去。 -
The teacher was telling us about the poet ' s life, when he went off at a tangent and started talking about his war experiences

The results of numerical experiments, using the four - dimensional variational data assimilation system of the nonhydrostatic mesoscale model mm5, show that : the tangent linear model and adjoint model conducted by keeping the " on - off " switches the same as the basic state, can provide a good approximation of the first - order information to the nlm perturbation and a good descent direction for the minimization procedure ; switching on and off at every other time step in the kuo cumulus parameterization scheme do n ' t impact the convergence rate of cost function ; the existence of the switches do n ' t impact improvement to the mm5 model rainfall prediction because that not only specific humidity, but also wind, temperature and pressure are assimilated into the model
非靜力中尺度數值模式mm5的四維變分資料同化系統進行的數值試驗結果表明： 「開關」變量保持與基態一致，所構造的切向線性模式能夠提供關于非線性模式擾動的一階近似，伴隨模式所計算的梯度值能夠為最小化過程提供較好的下降方向；郭氏降水參數化方案中對流每隔一個積分步的交替發生並不影響目標函數最小化的收斂速度； 「開關」變量的存在也不影響將風、溫度、氣壓和比濕結合起來同化對mm5降水預報準確性的提高。 -

Tangent linear and adjoint method of " on - off " switches are studied in this paper
本文研究了四維變分資料同化中有關「開關」變量的切向線性化和伴隨問題。 -
The two analytic examples show that : if the heating and moistening due to convection at the switch - on point is much smaller than all the other terms in the tendency equation, then keeping the " on - off " switches the same as the basic state will produce the right tangent linear model and adjoint model
兩個解析的例子表明：只要「開關」處的對流引起的加熱和加濕遠小於傾向方程的其它項，則保持「開關」變量與基態一致，能夠正確得到切向線性模式和伴隨模式。 -

Not developing these skills allows you to generalize or go off on a tangent, losing the point you are trying to make
不發展這些技巧會使你允許自己去概括或思想行動發生突然的改變，失去目標。
