After analysis and parison of virtues and hort ings of existing systemsafety evaluation ways, Artificial Neural Network, Artificial Intelligence and Expert System are used to build new system safety evaluation means. System safety evaluation model and intelligent expert system for fault diagnosis based on ANN have been put forth. Development and realization of visual neural network for system safety valuation and fault diagnosis provides new idea for system safety evaluation and accident mode diagnosis.

对已有的系统安全评价技术方法的优缺点进行了分析和对比，继而将神经网络技术、人工智能技术、专家系统应用于开发新的系统安全评价方法，提出了基于人工神经网络的系统安全评价方法和基于神经网络的智能故障诊断专家系统模型，开发了可视化的神经网络系统，为系统安全评价与事故模式诊断提供了新思路。

When the transient fault take place, the transmission line will reclose successful, so the level of the security and stability of network will be improved.

当故障为瞬时性故障时，线路重合成功，可大大提高系统的安全稳定运行水平。

This article enunciates preventive maintenance based on the state of key equipments in manufacturing execution system and management of workshop planning and scheduling. A comprehensive mathematical model between multi-key-equipments preventive maintenance and management of workshop planning and scheduling is offered.

1引言制造企业中关键设备是指发生故障时对整个生产系统影响较大的设备，特别是自动化流水生产线和联动设备；必须确保安全性能的设备，如动能设备；价格昂贵的精密、大型，重型、稀有设备；故障停机修理费用及停机损失大的设备等。

Fault Analysis and Treatment: An estimated following reasons: 1 self-completion computer emerged in the interface when activated by pressing the reset button, will appear in the start menu option to start, and the default choice is the safe mode, if the Press key, the system will enter the safe mode, restart the computer only needs to enter to the normal mode; 2 The system file is damaged or subjected to virus infection, resulting in Windows98 operating system can not enter into normal mode, can only enter the Safe Mode.

故障分析与处理：估计有以下几种原因：1）电脑在自检完成出现启动界面的时候按下了复位键，在启动时会出现启动菜单选项，并且默认选择的是安全模式，如果此时按键，系统便会进入安全模式，只需要重新启动电脑即可进入到正常模式；2）系统文件被破坏或遭受病毒感染，造成Windows98操作系统不能进入到正常模式，只能进入安全模式。

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.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

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。
