Taking the high precision on chip RTC as the time base control unit and using genetic algorithms to search the best OSCCAL register value, it will make the on chip RC oscillator generate a high precision clock for the MCU. This methord can be used fast and real time, so the CPU will get a stable clock source.

Multitasking operating systems come in two flavors: cooperative multitasking and preemptive multitasking. Linux, like all Unix variants and most modern operating systems, provides preemptive multitasking. In preemptive multitasking, the scheduler decides when a process is to cease running and a new process is to resume running. The act of involuntarily suspending a running process is called preemption. The time a process runs before it is preempted is predetermined, and it is called the timeslice of the process. The timeslice, in effect, gives each runnable process a slice of the processor''s time. Managing the timeslice enables the scheduler to make global scheduling decisions for the system. It also prevents any one process from monopolizing the processor. Bs we shall see, this timeslice is dynamically calculated in the Linux process scheduler to provide some interesting benefits.

多使命操作体系可化分为两类：非抢占式多使命以及抢占式多使命所有像Unix的变种体系以及很多现代操作系同同样，Linux提供抢占式的多使命模式在抢占式多使命模式中，调度步伐决议啥子时候进程中止，新的进程能够开始得到运行这个被强制挂起的动作就叫做抢占进程在被抢占前，运行的时间是预知的，这个时间叫做时间片究竟上，时间片是为每一个运行态的进程分配处置惩罚器的时间的一片管理时间片，使能调度步伐为体系做好整个的局面：胸怀～调度决议时间片也能阻止任何一个进程垄断处置惩罚器正如我们看到的，在Linux进程调度步伐中时间片是蜂蜜面膜动态计算出来的，这样带来很多利益

A Jiang is not a woodenhead, but still can make a mistake occasionally, calculating a tutorial so is newest the most complete, the problem still may appear when we are operated for the first time, and because be first time, write down the whole process that oneself handle very hard clear, bring about the person that has experience repeatedly possibly finally to come over to also cannot have installed your server completely.

阿江并不是一个笨人，但是有时候还是会犯错误的，所以就算教程是最新的最完整的，我们第一次操作的时候仍然可能出现问题，而因为是第一次，很难记清自己操作的全部过程，最后可能导致连有经验的人过来也无法完全设置好你的服务器了。

The Joseph father advantage takes a bath the number of times are not many, the approximately 23 weeks only then flush one time then to be possible, but the pet owner cannot be therefore loaf, still importantly recorded scratches every day for the dog class throws over the wool, can make to throw over the wool maintains along slides sharp; Because the Joseph bottomless wool level, throws over the wool in addition inborn along the straight relations, therefore throws over the situation which the wool very little appears ties a knot, in after dog flushing body, must thoroughly and eats Mao Mogan does, uses the unraveling to comb again combs the wool cascade is suitable, because the dog throws over the wool young, therefore in combing time then must double carefully, combs by suitable Canada, only then not Mao Shuduan, if needs, may use unraveling unrefined oil, when carding wool then did not fear that sleepy wrong with adds makes the painful dog; Because throws over the wool the fat secretion to be many, the ear easy Tibet dirt, skin also Yi Sheng to have the tinea, must therefore maintain the body clean clean.

补充约瑟爹利洗澡的次数不多，约两三星期才冲洗一次便可，但饲主也不能因此而偷懒，仍要紧记每天为狗儿流擦披毛，才能令披毛保持顺滑亮丽；由於约瑟无底毛层，加上披毛天生顺直的关系，所以披毛很少出现打结的情形，在替狗儿冲洗身体后，要彻底把毛抹乾及吃乾，再用解结梳把毛逐层梳顺，因为狗儿的披毛较幼，所以在梳理时便要加倍小心，以适当的加度去梳，才不把毛梳断，如需要的话，更可使用一解结毛油，梳毛时便不怕困错用加而弄痛狗儿；由於披毛的脂分泌较多，耳朵易藏污垢，皮肤亦易生有癣疥，所以要保持身体清洁乾净。约克夏狗是狗类型一个小狗品种，开发在19世纪在约克夏历史地区在英国。品种的定义的特点是它的小型和它柔滑的蓝色和棕褐色的外套。品种起绰号Yorkie和安置在狗小组的玩具狗部分由Fédération Cynologique国际歌和在玩具小组或伴侣小组由其他狗窝俱乐部，虽然所有同意品种是狗。一赢取的showdog和一条普遍的伴侣狗，约克夏狗也是其他品种的发展的一部分，例如澳大利亚柔滑的狗。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
