这是操作系统实验的调度算法，包含时间片轮转法，抢占式优先权算法，非抢占式优先权算法，先来先服务算法，短作业优先调度算法。

Preemption of system resources is used by the OS to enforce fairness in their use by programs, or to realize certain system level goals.

操作系统依靠对系统资源的抢占确保程序对资源的平等利用，或实现一些系统级的目标。

It is a modular, real-time, a powerful communications capabilities, preemptive multitasking embedded operating system.

它是一种模块化的、实时的、有强大通信能力的、抢先式、多任务的嵌入式操作系统。

Linux, like all Unix variants and most modern operating systems, provides preemptive multitasking.

所有像 Unix 的变种系统和很多现代操作系统一样， Linux 提供抢占式的多任务模式。

Own writing an embedded real-time preemptive multitasking operating system.

自已写的一个嵌入式实时多任务抢占式操作系统。

Thankfully, most operating systems designed in the last decade have provided preemptive multitasking, without Mac OS 9 and earlier being the most notable exceptions.

幸运的是，在近十年很多操作系统被设计成抢占式多任务模式，除了 Mac OS 9和早期的版本。

Multitasking operating systems come in two flavors: cooperative multitasking and preemptive multitasking .

多任务操作系统可化分为两类：非抢占式多任务和抢占式多任务。

A preemptive multitasking OS, such as UNIX/Linux, Windows NT/2000 or OS/2, frees up resources when ordered to by the operating system, on a time-slice basis, or a priority basis, so that one application is unable to hog resources when they are needed by another program.

抢先式多任务 OS（例如 UNIX/Linux、Windows NT/2000 或 OS/2）中，操作系统基于时间片或基于优先级命令应用程序释放资源时，应用程序释放资源，以便在其它程序需要资源时，正在使用这些资源的应用程序不会独占它们。

C/OS-Ⅱ,the Real-time kernel is a highly portable, ROMable, very scalable, preemptive real-time, multitasking kernel for microprocessors and microcontrollers.

C/OS-Ⅱ是一种可移植、可固化、可裁剪及可剥夺型的多任务实时操作系统，适用于各种微处理器和微控制器。

Secondly, the paper introduced how to implement safety detection by ultrasonic sensor, and presented systemically all the design of collecting and processing signals, storage circuit, lithium battery charging and discharging circuit, data communication circuit, keypads and LCD. This paper studied the code of uC/OS-II and introduced how to port uC/OS-II onto LPC2214. The Real-Time Kernel uC/OS-II is a highly portable, ROMable, very scalable, preemptive real-time, multitasking kernel for microprocessors and microcontroller.

然后论文具体介绍了如何实现超声波传感器进行实时安全监测，并系统的介绍了超声波监测系统的信号采集，处理，存储电路，锂电池充放电控制电路，数据通讯电路，键盘，显示器等的设计；也详细的介绍了多任务操作系统uC/OS-II的源代码及如何在LPC2214上移植等。uC/OS-II是一个移植方便的、可固化的、可裁剪的、占先的多任务实时内核。

Recall that, in the Kolmogorov axiomatization, measurable sets are the sets which have a probability or, in other words, the sets corresponding to yes/no questions that have a probabilistic answer.

延期开工的Kolmogorov宣布要衡量所有套职能有限许多坐标限制在于衡量子寅。换句话说，如果是/否的问题回答f可看的价值观念在许多最有限坐标，然后它有一个概率的答案。

The experimental results showed that the algorithm can filter singular points and remain fixity of the target edge.

实验表明：基于模糊理论的图像智能滤波方法比常规图像滤波方法运算量小，它既能去除奇异点，又能保持图像中目标的边缘不变性，具有很好的滤波效果。
