只能翻到这个程度了。后面的就不知道该怎么翻了。
看来高二的的确比高三的差不少~
而且估计错误一堆
项目介绍

虽然Pi Segment使用普通的计算机进行计算,但他并不会影响到计算机的正常工作,因为它利用的是计算机的剩余资源
Although the project uses ordinary computers to calculate, it doesn't affect the normal work, as it makes use of the unused computing resource.
所谓剩余资源就是指没有被有效利用的CPU资源。剩余资源是由于计算机当前的运算没有达到CPU的处理能力所产生的。现代的CPU速度越来越快,能够处理的信息也越来越多,但是这也使得它们在大多数时间并没有在全力工作,而是处于闲置状态,CPU的计算能力被白白浪费掉了
The so-called unused resource is the CPU resource not efficient used. It exists when the current calculation of the computer doesn't reach the ability of CPU. Now, the CPU is able to computes more and more quickly, and can deal with more and more information, but the development of CPU means that they don't use all the resource when working and leave unused, so the computing ability of CPU is wasted.
或许您会认为我每时每刻都在使用计算机,它真的会有空闲的时刻吗?答案是肯定的。耳听为虚,眼见为实,您不妨来验证一下:首先打开“Windows任务管理器”,切换到“进程”选项卡,拖动垂直滚动条,您会发现一个“映像名称”为“System Idle Process”的进程(系统空闲进程),请注意它所对应的“CPU时间”,如图所示(点击放大):
Maybe you consider that you are using the computer all the time, and it will not have free time. It is wrong. You can confirm this in this way: press "Cltr", "Shift" and "Delete" to open the window of "windows task manager", then switch to the Processes tab, you will find a process named "System Idle Process", please notice its "CPU time", as the graph shows. (left click here to watch the original sized picture)
“Windows任务管理器”显示的是当前系统中的进程信息。而“System Idle Process”是系统中一个特殊的进程,每当系统空闲时,它就会被运行。在Windows中,每个进程根据需要轮流使用CPU,而“CPU时间”指的就是对应进程从创建到现在所使用的CPU时间。因此,“System Idle Process”的“CPU时间”就是从开机到现在CPU的空闲时间。您会发现,这个“CPU时间”很大,甚至接近于您本次的开机时间。换句话说,大部分的CPU时间被浪费了,而Pi Segment所利用的正是这部分CPU时间
Windows task manager shows the current process information. "System Idle Process" is a special process of the system, it runs when the system is idle. Every prosess uses CPU according to its need in turn in the OS of windows, "CPU time" means the CPU time the corresponding process has used from it is established. So the "CPU time" of "System Idle Process" shows how long the CPU is idle since logging on. You'll find the "CPU time" of "System Idle Process" is quite long, even close to the time since you have logged on the computer. In other words, most of the CPU time is wasted, and Pi Segment makes use of this part of CPU time.
或许您认为,当CPU空闲时,计算机不会消耗资源。可实际并非如此,尽管现代的计算机都符合一定的节能规范,现代的CPU也支持节能模式,但是实际情况要比预想复杂的多。以下仅就使用者短时间离开或者只进行轻量级任务的情况进行分析;对于长时间不使用计算机的情况,我们建议您直接关闭电源。以一个主流的计算机为例,当CPU空闲时它会转入节能模式,此时它的功耗会减少几十瓦,但其他的部件所消耗的资源并未明显减少,资源的消耗依然很大。更普遍的情况是,您一直在计算机旁使用它,例如写文章、听音乐、看电影、浏览网页等,这些任务对现代的CPU来说九牛一毛,将会有大量的剩余资源被浪费;而此时,显示器(用电大户)肯定不能关闭
Maybe you consider that when CPU is idle, the computer doesn't consume resources. But this is not correct. Although computers now conform to a particular standard of energy saving , and the CPUs now support energy saving mode, the practical situation is much more complex than expected. Here shows the analysis of situation where user leaves for a short time or runs tasks not taking much computing resource; and to the situation where not using computer for long, we suggest you shut down the computer. Take an ordinary computer for example, when CPU is free, it will switch to energy saving mode, then its power will reduce by tens of watts, however, the power of other hardwares won't reduce obviously, and the computer will still consume a lot of resource. More general situation is that you are using the computer all the time, such as writing articles, listening to music, watch movies, browse websites and so on. These tasks is a piece of cake for the CPU, so a lot of unused resourse is wasted; meanwhile, the display, which consumes a lot of power, cannot be shut down obviously.
