一、分析的目的 了解逻辑电路的功能 二、分析的步骤 数字电路: 分组合逻辑电路、 时序逻辑电路两大类 功能特点：任意时刻的输出信号只与此时刻的输入信号有关

The reaction on the left end is not exact because 1. The order of interpolation is too low, a higher order of interpolation would give the right reaction 2. The distributed load attributed to node one does not ke it into the solution

Unit #10- Principle of minimum potential energy and Castigliano's First Theorem Principle of minimum potential energy The principle of virtual displacements applies regardless of the constitutive law. Restrict attention to elastic materials(possibly nonlinear). Start from the Pvd

What new element is Castigliano s Theorem introducing? 1. None, it's just a particular case of the PMPE 2. It's a totally different principle that allows to obtain solutions of elasticity problems with unprecedented accuracy and efficiency in- cluding relativistic effects

超临界流体色谱 1962年Klesper发表“用超临界的二氯二氟甲烷、二氯 一氟甲烷等分离镍卟啉异构体”的第一篇超临界色谱 论文。 1981年Novotny和Lee首次报道了毛细管超临界色谱技 术。 但1990s开始淡出仪器领域

Concept Question Which of the following statements is true 1. The PVD and the PMPE are equivalent 2. The PVD is more general 3. The PMPE applies to any kind of material 4. The stationary character of the potential en ergy is equivalent to the Pvd for elastic ma terials
