双11淘宝网购焦点图切换特效，平板风格的图片切换特效，jQuery淘宝商城多格焦点图效果。如果索引值等于li元素个数，说明最后一张图播放完毕，接下来要显示第一张图，即调用showFirPic()，然后将索引值清零，通过callback，在动画结束后把ul元素重新定位到起点，然后删除最后一个复制过去的元素。。。

优化命题的解决存在于许多领域，对于国民经济的发展也有着巨大的应用前 景.随着优化对象在复杂化和规模化等方面的提高，基于严格机理模型的传统优化 方法在实施方面变得越来越困难. -Optimization solution proposition exists in many areas, for development of the national economy also has great application prospect. With the optimization of the object in a complex and large-scale areas such as the improvement of the mechanism model based on strict traditional optimization methods in the implementation has become more to the more difficult.
