要熟悉流管柱层析法需要适当的练习。此影片将会让从你填充 的适当条件技巧开始、填充及进行管柱层析,甚至用管子做一个微 管柱层析。 It takes considerable practice to master the art of \running a column\. This video will get you started, with tips on picking appropriate conditions, packing and running a column, monitoring separation, and even making a micro-column from a pipet

Ⅱ. Listening skills How to Overcome Fears of Flying If you are afraid of flying, there are specialists who can teach you how to deal with your fears and They will find out if a nearby airport has special training programs for people who are afraid to fly. Many airports do. How would such a program work? First, a specialist will take your group to the airport to watch the planes take off and land. A

A pendulum is a rigid body suspended from a fixed point (hinge) which is offset with respect to the body's center of mass. If all the mass is assumed to be concentrated at a point, we obtain the idealized simple pendulum. Pendulums have played an important role in the history of dynamics. Galileo identified the pendulum as the first example of synchronous motion, which led to the first successful clock developed

In this lecture, we will revisit the application of Newton's second law to a system of particles and derive some useful relationships expressing the conservation of angular momentum. Center of Mass Consider a system made up of n particles. A typical particle, i, has mass mi, and, at the instant considered, occupies the position Ti relative to a frame xyz. We can then define the center of mass, G, as the point

在实际的工程计算中,经常会遇到求n阶方阵A的特征值(Eigenvalue)与特征向量 Eigenvector)的问题。对于一个方阵A,如果数值λ使方程组 Ax=x 即(A-In)x=0有非零解向量(Solution Vector)x,则称λ为方阵A的特征值,而非零向量x为 特征值λ所对应的特征向量,其中In为n阶单位矩阵
