夹逼 1. This article introduces the Upper and Lower Solutions Method for differential equations,applicationing limit squeeze rule and taking elliptic partial differential equations as an example. 引进微分方程上下解的概念,应用极限夹逼准则思想,以椭圆型偏微分方程为例,用上解与下解来夹逼证明了半线性椭圆型...
夹逼准则与椭圆型偏微分方程的上下解方法 2. error frequency fidelity criterion 差错频数逼真度准则 3. probability of error fidelity criterion 差错概率逼真度准则 4. Given this pressing situation, we must move forward, or we will fall behind. 形势逼人,不进则退。 5. An Analysis on the Pinchin...
例如:极限定义求法、柯西收敛准则法、单调有界原理法、夹逼性定理求极限法、定积分的定义计算极限法、利用(海涅)归结原则求数列极限法、洛必达法则求极限法、级数收敛的必要条件求极限法、幂级数求极限法等等.本文主要讲述数列极限的不同求法,当然我们还会发现同一数列极限可用不同方法来求.[translate]...
