翻译原文:Each layer only communicates with the adjoining layers through well defined interfaces. Thus, a user command may percolate through the layers to reach the lowest layer which directly interacts with the architecture. This layer is called the OS kernel. Many modem OSs, particularly Unix, use such OS structure. The porting effort of such an OS is determined by the size of the OS kernel.

翻译答案:每层只需通过定义好的接口与相邻的层通信。因此,用户的指令可以透过各层直接达到与结构直接交互的最底层,这一层又称为操作系统内核。许多现代的操作系统,特别是Unix,都使用这种结构。这种操作系统的移植难度大小只由系统内核的大小决定。

读完一本书翻译原文:One Sunday morning Squealer announced that the hens, who had just come in to lay again, must surrender their eggs. Napoleon had accepted, through Whymper, a contract for four hundred eggs a week. The price of these would pay for enough grain and meal to keep the farm going till summer came on and conditions were easier.
When the hens heard this, they raised a terrible outcry. They had been warned earlier that this sacrifice might be necessary, but had not believed that it would really happen. They were just getting their clutches ready for the spring sitting, and they protested that to take the eggs away now was murder. For the first time since the expulsion of Jones, there was something resembling a rebellion. Led by three young Black Minorca pullets, the hens made a determined effort to thwart Napoleon’s wishes. Their method was to fly up to the rafters and there lay their eggs, which smashed to pieces on the floor. Napoleon acted swiftly and ruthlessly. He ordered the hens’ rations to be stopped, and decreed that any animal giving so much as a grain of corn to a hen should be punished by death. The dogs saw to it that these orders were carried out. For five days the hens held out, then they capitulated and went back to their nesting boxes. Nine hens had died in the meantime. Their bodies were buried in the orchard, and it was given out that they had died of coccidiosis. Whymper heard
nothing of this affair, and the eggs were duly delivered, a grocer’s van driving up to the farm once a week to take them away.
翻译答案:一个星期天早晨,斯奎拉宣布说,所有重新开始下蛋的鸡,必须把鸡蛋上交。因为通过温普尔牵线,拿破仑已经承诺了一项每周支付四百只鸡蛋的合同。这些鸡蛋所赚的钱可买回很多饲粮,庄园也就可以坚持到夏季,那时,情况就好转了。

 鸡一听到这些,便提出了强烈的抗议。虽然在此之前就已经有过预先通知,说这种牺牲恐怕是必不可少的,但他们并不相信真会发生这种事。此时,他们刚把春季孵小鸡用的蛋准备好,因而便抗议说,现在拿走鸡蛋就是谋财害命。于是,为了搅乱拿破仑的计划,他们在三只年轻的黑米诺卡鸡的带动下,索性豁出去了。他们的做法是飞到椽子上下蛋,鸡蛋落到地上便打得粉碎。这是自琼斯被逐以后第一次带有反叛味的行为。对此,拿破仑立即采取严厉措施。他指示停止给鸡供应饲料,同时下令,任何动物,不论是谁,哪怕给鸡一粒粮食都要被处以死刑。这些命令由狗来负责执行。坚持了五天的鸡最后投降了,又回到了鸡窝里。在这期间共有九只鸡死去,遗体都埋到了果园里,对外则说他们是死于鸡瘟。对于此事,温普尔一点也不知道,鸡蛋按时交付,每周都由一辆食品车来庄园拉一次

系统内核
这种包含在系统内核中的机制被列举在表5-1
内核取得控制时有如下情形:
1.一个突发的情形出现在系统中。
2.系统决策模块明确诉求一个内核机制。

操作系统核心
经典的机械结构在操作系统的核心中的在表5-1中被列举。
在以下几种情况,核心是受控的
1. 系统中发生了特殊情况
2. 一个操作系统模型明确被引用与一个核心机械中


Snowball对这一切一无所知。谣传它躲在了邻居的农场中,要么在Foxwood或者Pinchfield中。Napoleon比以前更轻视其他的农场了。在一个堆满了十多年的灌木林中。Whymper告诉Napoleon要在这个好季节中卖掉那些木材。Pikington和Frederick都想要收购这些东西。Napoleon有点犹豫,不知道要卖给谁。值得注意的是,当他打算卖给Frederick时,就有声音说Snowball可能藏在Foxwood,当倾向与Pikington时,又说Snowball在Pinchfiled

操作系统内核
操作系统内核包含的典型机制在表5-1中列出。
当以下情况发生时内核接管控制:
1、在系统中发生了一个异常情况时。
2、操作系统的策略模块明确地(explicitly)调用内核中的一个机制。

操作系统内核:
操作系统内核包含的经典机制在表5-1中列出。内核当下面情况的时候获得控制权:
1、系统出现异常情况的时候
2、一个操作系统策略明确要执行某一个内核机制的时候。


动物农场:
这阵子都没有看见过snowball。谣传他正躲在相邻的一处农场里,不是foxwood就是pinchfield。
在这段时间里,napoleon和其他农场的关系已经比以前要好一些了 。碰巧在农场院子里面有一堆木材已经堆放在那里十年了,
是早年间青林一个山毛榉灌木林留下来的。现在那些木材已经很适合卖掉了,whymper建议napoleon卖掉。
pilkington先生和frederick先生都想要买这些木材。napoleon正在犹豫,不能下定决定要卖给谁。
但是无论何时,当它倾向于和frederick达成协议的时候,就会有人公布snowball藏在foxwood农场,但是当它倾向于和pilkington的时候,
又有人会公布snowball藏在pinchfield农场了。


Only the mediocre are always at their best.
只有普通人一直处于最佳状态。

翻译计算机英语,讨厌的地方就是一旦一个专业词汇不知道什么意思就不知道句子在说什么,好在我是计算机专业的,但是也好不喜欢翻译这种纹章

还是读故事有意思多了,

好想念snowball啊

操作系统内核
通常包含在系统内核中的机制如表5-1所示,当发生如下情况时内核被控制:
1.系统异常情况发生时。
2.操作系统策略模块明确调用内核机制。
