简介：一天，netsoar兄弟发消息问我about:blank页面保存在什么地方？我有些纳闷，这个东西不是默认的IE空白吗？真有这个页面？从来没有看到过，于是全盘搜索，并没有发现蛛丝马迹，那about:blank究竟是怎么回事呢？我们听听netsoar碰到的问题吧，或许从中中以找到答案……

简介：符号活动可分为一维、二维、三维、四维、多维、跨维六大类。人类最广泛、最持久的人际交往,是在四维物理空间增加了＂心理感受＂、＂价值判定＂等坐标轴的多维符号活动。无论是人际交往中的众际交往还是个际交往,都需要机智调动＂物理距离＂、＂心理距离＂、＂价值判定距离＂等多维空符号才能成功。多维空符号具有多维性和差异性。良好的心态容易接受＂必备原则＂和＂适度原则＂,提高人际交往效益。

简介：作为《空符号blank-sign在人际交往中的价值初探》的姐妹篇,在前篇的基础上探析了＂个际交往＂中的空符号。个际交往是最普遍、最不可逃避的人际交往,它包括陌际交往、友际交往、恋际交往、亲际交往,其＂间隔＂、＂离别＂、＂代沟＂等空符号的价值更微妙、更需探究。机智启动＂物理距离＂、＂心理距离＂、＂价值判定距离＂等可操作性程序,有望提升人际交往的境界及效益,促进社会和谐。
