说明：  克里金(Kriging)插值法又称空间自协方差最佳插值法，它是以南非矿业工程师D．G．Krige的名字命名的一种最优内插法。克里金法广泛地应用于地下水模拟、土壤制图等领域，是一种很有用的地质统计格网化方法。它首先考虑的是空间属性在空间位置上的变异分布．确定对一个待插点值有影响的距离范围，然后用此范围内的采样点来估计待插点的属性值。该方法在数学上可对所研究的对象提供一种最佳线性无偏估计(某点处的确定值)的方法。(Kriging interpolation, also known as spatial autocorrelation optimal interpolation, is named after d.g.krige, a mining engineer in South Africa. Kriging method is widely used in groundwater simulation, soil mapping and other fields. It is a very useful geostatistical grid method. Firstly, it considers the variation distribution of spatial attributes in spatial position, determines the range of distance that affects the value of a point to be inserted, and then estimates the attribute value of the point to be inserted with the sampling points in this range. This method can provide the best linear unbiased estimation (the determined value at a certain point) for the studied object mathematically.)

说明：  python源码剖析，带详细目录，觉得好请点赞(Python source code analysis)

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。。。

说明：  本章实现了一个完整的四人网络麻将游戏，该程序集服务器与客户端功能与一体。本章主要介绍了非对等的网络服务功能的建立，传输信息的序列化，建立虚拟的三维空间，绘制图形和显示位图，在内存中创建位图和绘制图形等。 (This chapter implements a complete network of four mahjong game, the assembly server and client-side functionality and integration. This chapter focuses on the non-reciprocal function of the establishment of network services, transmission of information sequences, building a virtual three-dimensional space, drawing graphics and display bitmaps, create a bitmap in memory and drawing graphics.)

主要基于微信小程序获取RSSI信号，然后发送至后台进行算法解析，后台再将解析出来的信息发送到前端(The RSSI signal is obtained mainly based on the WeChat applet, and then sent to the background for algorithm analysis, and the parsed information is sent to the front end in the background.)
