A important result is the one-order expression of AR Yt = DYt-1 + E, from paralleling a high-order differential equation transformation into a one-order differential equation system, the one-order expression exposes that the AR is only a certain more-multivariable power series processAnd, if a process is described as an AR, the sufficient and necessary condition is the spectrum norm A of the coefficient matrix D less than one.

在网上搜集总结了以下几个方面，提供文本连接到站点上主要的页面，根据网站大小，网页数目的多少甚至可以连接到所有的页面；为每个连接提供一个简短的介绍，用以提示访问者这部分内容是关于哪一方面的；在网站地图和文本超连接里面提及最主要的要害词语，帮助搜索引擎识别所连接页面主题是关于哪一方面的；帮助引擎索引一些动态页面，由于一些页面将是动态产生的，假如不是用户行为调用将不会显示出来，可以将此连接放在网站地图上，以帮助引擎索引重要的动态页面；为了使网站地图吸引网络蜘蛛的访问，一定要在连接后面写上一定的描述性语句并使用此连接的要害词进行简单描述，但不能过渡的使用要害词，否则会适得其反；因为一般蜘蛛只抓前三级页面，所以网站地图越平越好，这里指的是逻辑路径，而不是物理路径。

阿祥成长在西北偏远的一个小山村里，还没出生的时候，父亲就因为一次病故离开了人世，出生后不到2岁，母亲又跑了，只剩下他的爷爷奶奶养活他，但是好景不长，他的爷爷奶奶也相继去世，这样，由于小时候家里条件不好，阿祥是靠街坊邻居的接济长大的，读小学的时候，他一放学就去放羊，读高中的时候，参加高考的前一年，下煤矿挖煤，就这样，靠着自己的努力，考上了西北农林科技大学，正式进入了大学校园，成为他们村唯一一个考上过大学的人，但是，由于家境贫困，阿祥经常吃不饱饭，每次都是馒头白菜过，他于是想了很多办法去挣钱，连给同学代写情书都干过，就为了混一顿饱饭，到后来又学会了网页设计，开始跟人家做网站挣钱，也从此对互联网产生了兴趣。
