In order to solve this problem, this paper first presents a transparent computing system based on the Godson platform, and then analyzes some main technologies introduced in the design, such as the multi-OS remote booting protocol, the virtual disk mechanism, the virtual memory and swapping mechanism as well as the user and resource management.

为此，文中提出了一种基于龙芯平台的透明计算机系统，着重讨论了实现该系统的一些关键技术，如多操作系统远程启动协议、虚拟磁盘机制、虚拟内存与交换机制、用户及资源管理等。

Computers are so fast that a human being cannot effectively make such real- time choices. On most multiprogramming system, the processor's time is managed by an operating system module.

计算机的速度是如此之快，以致于使人类不能有效地做出实时的选择，在大多数多道程序设计系统中，处理器时间是由操作系统模块来管理的。

Heterogenous commercial operation system installed on every node computer, the whole cluster is constructed on the connection between those independent nodes. Thus, we can see the important role of management software in heterogenous cluster systems.

在每个结点计算机上安装有不同商业化的操作系统（AIX、LINUX、NT等），整个异构机群建立在这样一些独立结点的连接之上，可见管理软件在异构机群系统的重要地位。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
