在编辑WORD文档时操作一段时间会弹出内存不足,请现在保存文档
在编辑WORD文档时操作一段时间会弹出"内存不足,请现在保存文档",然后按"确定",又弹出一个对话框"内存或磁盘空间不足,无法运行语法检查",按好"确定"之后仍然又重复前面的提示,无法关闭WORD,请各位高手帮我想想这会是什么原因,我试过将原来一个文件中有很多张表格拆成了多个文件来存储,然后仍然出现这种情况,不知道是什么原因,希望大家能够帮帮我,谢谢了!!!:) 请确认你的安装OFFICE的磁盘空间有足够的空间,此问题最大的可能是你的内存的问题,内存太小或内存质量比较差,请用以下方法尝度试:1 把内存加大或换内存或把虚拟内存设到内存的2倍2:重新安装OFFICE
人类可用思想直接控制电脑
人类可用思想直接控制电脑 美国日前公布了的一项试验研究成果:4个试验者戴上布满电极的“思考帽子”后,可以运用他们的思想来直接控制电脑。据路透社12月6日报道,当日参与这项试验的研究人员对外发布了这项试验结果。他们说,试验中的这种装置日后将会投入应用,以帮助残疾人驾驶机动轮椅和操纵假肢。
报道说,研究人员对两位使用轮椅的局部残疾人和两位健康人进行了试验,这4个人都是志愿参与试验的。研究人员让这4个人头戴含64个电极的帽子坐在一个电视屏幕前,电极帽子将记录下他们大脑的活动。研究人员发现,两位残疾人对试验的反应要好于两位健康人,这可能是由于残疾人有更强烈的完成试验的愿望,或者由于他们的大脑已经习惯于去应付自身的残疾,因而更为敏感。
参与这项研究的纽约州立大学的丹尼斯·麦克法兰和纽约州政府卫生部的乔纳森·沃尔波在研究报告中说:“试验结果表明,人们能通过头皮记录的脑电图来同时控制电脑光标的速度和光标的准确移动。”他们解释说,这个试验的关键在于一个特殊的电脑运算法则,也就是一个电脑程序。这个程序能将人大脑发出的信号翻译成有实际意义的指令,这个指令会要求电脑去完成人们所希望它做的事情。
在此之前,早已有研究人员做过试验:通过在猴脑里植入的电极而让猴子操纵电脑。但是,现在进行的这项试验却不需要任何手术,也不需要在大脑里植入任何东西。这项研究成果发表在最新一期的《美国国家科学院院刊》上。
