内核

"Gratitude,fraternity,opening-up and transcendence",as new Tangshan humanistic spirit,is not only the core of Tangshan spirit but also the concretization of national spirit and the practicalization of human spirit.

&感恩、博爱、开放、超越&的新唐山人文精神不仅仅是唐山精神的坚实内核，也是民族精神的具象化和人类精神的实践化。

On the control strategy of liquid temperature, many control techniques were taken into account ,such as fuzzy control, expert PID control . Through simulation in MATLAB and many practical tests, fuzzy precompensation PID strategy was adopted . The system used μC/OS-II as the real-time kernel. And Keil C51 compiler was used as the nether application software development environment. So it's easy to extend and maintain the system.

在实验温度控制上，详细研究了多种控制方案，包括模糊控制，先进PID 控制等，通过多次计算机仿真实验和实际试验选取了模糊控制+预补偿PID 的新型复合控制技术，实现了温度的精确控制；在软件开发时选用了成熟的源代码公开的μC/OS-II 实时嵌入式操作系统作为实时内核和Keil C51 编译器作为下位机软件开发环境，极大地方便了系统的扩展和维护。

On the control strategy of liquid temperature, devoleping precompensation PIDstrategy was adopted based on the previous works. Considering the whole system, weadapt Linux OS that is steady than the MCU. It can complete the experiment by manypeople and many PC through the net. The system used Linux operation system based onthe ARM9 as the real-time kernel and the nether application software developmentenvironment. So it\'s easy to extend and maintain the system.

在实验温度控制上，详细分析了多种控制方案的优缺点，在改进前人的控制算法基础上选取了改进的分阶段预补偿PID控制技术，实现了温度的精确控制；从整个系统的需求出发，采用了比单片机更稳定的Linux操作系统，通过网络使得多人多机能够参与到实验中，更好的完成了杂交实验，实现了全系统的优化；在软件开发时选用了基于ARM9的Linux操作系统作为实时内核和下位机软件开发环境，极大地方便了系统的扩展和维护。

The establishment of socialist core value system should be based on the unified, dialectical practice of culture. Value is the core of culture, and the orientation of value determines the direction and mode of cultural development. On the other hand, the state of culture constitutes the external environment of value and value system establishment, and the prescriptiveness of cu8ltural ecology influences the formation and determination of value system.

核心价值体系的时代确立，更应有文化历史性的辩证统一实践，因为价值本是文化的核心内核，价值的导向性决定着文化发展的方向与模式；而文化的状态是价值及其体系得以树立的外在环境，文化生态的规约性造就着价值体系的形成与确立。

And all of that source is portable, except for this tiny kernel that you can (provably: I did it) re-write totally from scratch in less than a year without having /any/ prior knowledge.

所有{linux现今的}源代码都是可移植的，除了这个微小的内核，也就是说你可以，在完全没有/任何/基础知识的情况下，1年以内你可以重头开始重新写出来。

For example, it might need to release locks before calling schedule and reacquire them after or react to other events.

需要注意的是，内核代码在循环体内常常需要完成一些其他的任务，比如，它可能在调用schedule之前需要释放掉锁，而在这以后再重新获取它们，或者响应其他的事件。

Note that kernel code often has to perform various other tasks in the body of the loop. For example, it might need to release locks before calling schedule and reacquire them after or react to other events.

需要注意的是，内核代码在循环体内常常需要完成一些其他的任务，比如，它可能在调用schedule之前需要释放掉锁，而在这以后再重新获取它们，或者响应其他的事件。

File-blocks cache – when a file is opened, the kernel checks with the remote server whether to fetch or revalidate the cached attributes.

文件块缓存-当一个文件被打开时，内核与远程服务器一起检查是否取或重新设置缓冲的属性。

Today the global overcast of television is a worldwide phenomenon. Meanwhile the "localization" of television broadcast is still the kernel of the life force and rivalrous ability of the television media.

在电视传播覆盖全球的今天，&本土化&传播仍然是电视媒体最有生命力和竞争力的内核。

The conditions for the formation of different surface morphologies have been discussed in terms of the contact angle of SEPs at the interface between water and chloroform, and a contact angle slightly greater than 90o is found to be pre-requisite for the formation of honeycomb structures.

我们通过改变复合物中烷基链密度、烷基链长度以及多金属氧簇内核的尺寸，详细研究了复合物的亲疏水性和尺寸对所形成的多孔膜形态的影响，并在得到高度有序的多金属氧簇复合物有序多孔膜的同时，首次获得了有序多孔结构的形成规律，即只有界面接触角稍大于90o的复。。。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
