The main findings of the study are as follows:(1) Both N2 and P3 are the characteristic ERPs under nogo inhibition,but P3 amplitude is a good indicator of inhibition processing depth;(2) Through ERP waveforms separation from encoding of stimuli sequence,we verify that the capacity of visual working memory is about 4 units;(3) In the go/nogo sequence response, encoding is mainly the function of right hemisphere, but inhibition retrieval is concentrated on left frontal area and anterior cingulated cortex.

本研究获得了以下结论：(1)在nogo抑制条件下，N2和P3波是特征的抑制波，但P3的波幅是反应抑制加工深度的良好指标；(2)对刺激的顺序编码加工的ERP验证了工作记忆的处理单元的容量为4左右；(3)在Go/nogo序列反应中，编码加工体现为右脑优势，而抑制提取的加工负波集中在左脑前额和前角回区。

The paper has experimentally studied the explosive limit ed oxygen concentration and critical oxygen concentration of effect of coal mine combustive gases.

目前对可燃性气体的临界氧浓度的研究大多数都是对单元气体进行的，通过对煤矿可燃性气体的爆炸极限氧浓度和临界氧浓度进行的实验研究，对煤矿可燃性气体临界氧浓度的影响因素进行了分析，得出的数据及结论为煤矿瓦斯的安全防爆工作提供了理论基础。

As the main work and energy consuming device of small and medium sized air-conditioning units, scroll compressors have much inapproachable advantages over any other kinds of compressors, such as low level of vibration and noise, light weight, high efficiency, high reliability, low energy consuming.

涡旋压缩机作为中小单元制冷空调系统的主要工作与耗能装置，具有比其他各种形式的压缩机无可比拟的优越性，如运动部件少、结构紧凑、低噪音、低振动、高效率、高可靠性和低能耗等。

In the whole system, each intelligential unit work independently and intercommunicate. The users can freely configure to realize kinds of functions according to their demands. So this system integrates advantages of DCS and fieldbus. This paper takes oneintelligential unit-mobile roll tension control unit as concrete object toanalyze.

整个系统设计时既可以采用RS-485技术，又可以采用CAN技术，它具有全数字化信息双向通信、多变量处理能力、自诊断等功能，系统中的各智能化单元工作独立，又可相互通信，在系统总线上，用户可以根据需要自由组态，灵活实现各种现场功能。
