Secondly, commencing with the human error theory, the author traces human errors back to their cultural root in the complex socio-technical system, as thus establishes the assessment system of enterprise safety culture and its conceptual model, in which decision level, management level, and execution level are principal parts, which is studied from two aspects of macroscopic and microscopic, which is described from two perspectives of period and time point, and which is discussed in two environments of external and interior.

2从人因失误理论出发，探究了复杂社会技术系统中人因失误的安全文化根源，由此创建了以企业决策层、管理层、执行层为主体的，从宏观和微观两个层面、基于时期和时点两种时间视角、外部环境和内部工作环境两种空间环境视角的企业安全文化评价体系，给出了其概念模型。

This is an untouched measuring way. The cameras are calibrated in the way of RAC two steps, first. With the polynomial interpolation, the pictures catched from the steel plate are treated to detect the edge in subpixel with a cross window arithmetic operators, which can fit non uniform illumination, keep the edge character and do filter in a better way. Three-dimensional scenery could be rebuilt from the two-dimensional pictures with the methods of least square fitting and contradictorily clairvoyance. Thus, the distance and its variance of two points in the given position of the plate can be achieved. It is expected that this study can provide a new and useful tool to the research on the theory of distortion of line heating.

这种非接触的测量方式，采用RAC两步法对摄像机进行标定，然后对采集到的钢板图像进行分析处理，通过多项式插值的方法，采用具有保持边缘特征和滤波功能，且能适应非均匀照明的十字窗图像边缘检测算子进行象素级边缘检测，再用最小二乘拟合法和逆透视法对二维图像进行三维重建，便可测出钢板上给定点的距离及其变化值，以期为水火弯板的变形机理研究提供一种新的检测手段。

New type of water chemistry for utility drum boiler and its principle and characteristic Two kinds of water chemistry's main principle and characteristic are detailedly analyzed. Against the problem of high eroding speed, high Fe content in feed water and boiler water, high scaling speed, short chemical cleaning interval, needing poisonous chemical deoxidant, etc for drum boiler's deoxidization water chemistry and difficulty of using oxidation water chemistry, a new type of water chemistry is put forward on the basis of analyzing the characteristic of whole power station's water steam cycle system, principle of two kinds of water chemistry and their practical effect in every cycle stage. Considering two water chemistry's merit, a new water chemistry called Limited Oxidation Water Chemistry is put forward, which is a local slight oxidization no-deoxidant water chemistry. And the proposed method's principle, control parameter, applying condition, start-lay up and emergency measures are initially calculated and analyzed.

三、新型汽包炉水化学工况的提出及其原理和特点详细分析了国内外现行两大类水化学工况处理的核心原理和特点，针对现行汽包炉还原性水化学工况处理所存在的系统腐蚀速度相对较大、给水和炉水铁浓度高、锅炉结垢速度快、机组酸洗间隔短、无法避免有毒化学除氧剂的使用以及氧化性水化学工况在汽包炉机组上应用的困难等问题，在详细分析电站整个水蒸汽循环系统的特点、两类水工况处理的原理和对循环中各段处理的实际效果等的基础上，综合两者的优点，提出了一种新型的局部轻微氧化性无除氧剂汽包炉水化学工况－"汽包炉有限氧化性水化学工况"处理原理，并初步计算、分析和确定了该种新型水化学工况的主要工艺控制参数、应用条件、启停与紧急情况处理等。
