It′s found that the GVD-caused chirp in the exponential type of DDF is least likely to be affected by the initial chirp,the GVD-caused chirp in exponential, linear,Logarithm and Guassian types of DDF has the synchronous character of saturation as the nonlinear-effect-caused chirp ,and the two kinds of chirp are found to counteract to balance, which makes the sum chirp tend to be zero.

First of all,we have given some of the basic concepts of differential equations, described the constant coefficient linear ordinary differential equation solution, for a class of second-order variable coefficient linear ordinary differential equation initial value problem, an approximate solution, the method is first unknown function of a definition for N sub-interval, and then in between each district within a constant coefficient ordinary differential equations similar to the replacement, the solution has been the problem as similar to the original analytical solution, and then gives a detailed second-order change order coefficient of linear homogeneous ordinary differential equation solution examples, the examples of the approximate method proposed in this paper is valid.

首先给出了微分方程的一些基本概念，讲述了常系数线性常微分方程的解法，针对一类二阶变系数线性常微分方程初值问题，提出了一个近似解法，本方法是先对未知函数的一个定义区间作N等分，然后在每一个小区间内用一个常系数常微分方程近似替换，所得到的解作为原问题的近似解析解，随后详细给出了一个求二阶变系数齐次线性常微分方程的解的实例，该实例说明本文提出的近似方法是有效的。

Maintain deflector if the size of the same voltage, the voltage change is accelerating, we can see a very accelerated voltage reduce, electron beam deflection angle instead of increasing, it is because of low accelerating voltage, the electron velocity smaller horizontal direction, electronic deflection plates in the field of the role of the extended time, the angle of deflection increases .

如果保持偏转板的电压大小不变，改变加速极的电压，可以看到加速极的电压减小，则电子束偏转的角度反而增大，这是因为加速极电压低，则电子的水平方向速度变小，电子在偏转板中受电场力作用的时间加长，所以偏转的角度增大。

It's a scissor summer opening for the pulp our life has clumped recently into. Rust is a hindrance we can slice in spite of.* we are in the meadow we are in the garden planted with pottery shards and the principles of palmistry wherever we are there is plenty of unreal fruit on the trees jicama kiwi extra-ordinary things to eat wherever I am * I want to hunch with you where the berries are flush watch the bushes go green and you blood blue.

它是剪刀的夏天为我们生命最近聚集一起形成的果肉打开锈是我们无休止地切成一片一片的妨碍*我们在草地上我们在种满碎瓷与看相的规则的院中无论我们在哪里树上总是结满不真实的果实小罗卜弥猴桃我何时何地都要吃的超级普通的东西*我想和你一起弯着在遍地草莓泛红的地方看灌木丛变绿你的血变蓝。
