左侧大图片右侧缩略图的js网页幻灯代码,也就是大家所熟悉的焦点图特效,有人也称之为"图片切换",鼠标点击缩略图后,即可切换左边的大图片轮番,当无鼠标操作的时候,它可自动轮播依次显示图片,目前来说,这款风格和功能的幻灯片十分流行.

这是一个贪吃蛇游戏的源程序，可通过控制蛇身的上下左右移动吃到食物后，蛇身增加，最后可输出成绩(This is a Snake game source code can be up and down by controlling the snake to eat the food and move around, the snake increases, the final output results)

说明：  我用过了，很好的！！建议你们也看看！不知道能不能看到！(I used, and very good! ! Suggest that you also take a look at! Do not know can not see!)

模糊多模型+概率数据关联的例子： 多模型包括一个直线的匀速和两个匀速转弯模型，模型概率随着仿真次数调整使得跟随轨迹。(This is a example of "Fuzzy interacting multiple models target tracking in the multiple passive sensor system")

双重差分估计 双重差分模型（difference-in-difference，DID）近年来多用于计量经济学中对于公共政策或项目实施效果 的定量评估。 通常大范围的公共政策有别于普通科研性研究，难以保证对于政策实施组和对照组在样本分配上的完全随机。非随机分配政策实施组和对照组的试验称为自然试验（naturaltrial），此类试验存在较显著的特点，即不同组间样本在政策实施前可能存在事前差异，仅通过单一前后对比或横向对比的分析方法会忽略这种差异，继而导致对政策实施效果的有偏估计。(Quantitative evaluation of policy or project implementation effect. Generally, a wide range of public policies is different from general scientific research, and it is difficult to ensure that the sample allocation for the policy implementation group and the control group is completely random. The non-randomly assigned policy implementation group and the control group are called natural trials, which have significant characteristics, i.e. there may be prior differences between the different groups of samples before the implementation of the policy, and this difference will be ignored only through a single pre-and post-comparison or horizontal comparison analysis method, which leads to the policy. Biased estimation of implementation)
