Oilcan is a kind of typical rigid target with big backscattering coefficient, which takes on point figure if the resolution of SAR image is not very high; these point targets to be recognized gather together, and form a target region with some distribution area; the center of the region appears as a beeline, and the speckle noise appears scattered, therefore, considering the different grey distributions between point target and speckle noise region and the space geometry distribution, these point targets can be recognized by this algorithm.

由于在高分辨率情况下，合成孔径雷达图像中油罐个体的散射分别体现为由若干高亮度点围成的椭圆，待识别油罐目标的模糊边缘呈不连续的椭圆状，因此从二值化后的SAR图像中识别出拟目标的不连续边缘，判断其是否满足目标边缘特性来识别出最终结果，采用该方法解决了这类高分辨率下椭圆状目标的识别问题。本文运用了基于Gauss核函数支持向量机的SAR图像典型目标识别方法。

A oil warehouse was served under the backgroud of engneering application in this paper. Based on analyse and distinguish of oilcan fire, hazardous factors in explosion and accidental characteristics, consequently, inherent hazard scale of the oilcan section was educed by using DOW's fire explosive index method. In that way those errors between safety precaution and present criterion were also definited by analysising and calculating the effect of safty compensating coefficient in deducing hazardous scale of oilcan fire.

本论文以某油库作为工程应用背景，在对油库的火灾、爆炸危险因素及事故特点进行分析、辨识的基础上，应用道化学火灾爆炸指数评价法，对油库中最危险的油罐区进行定量评价，得出油罐区的固有危险等级，分析、计算了不同状态下安全补偿系数对降低罐区火灾危险等级的影响，明确了所采用安全措施的有效性及与现行标准规范要求尚存的差距。

本文理论为确定明槽和管道低浓度含沙流动中扩散系数在断面上的分布提供了依据。

The results showed that the aluminum plates had a much better effect than zinc plates in identifying crystalline free silica. The all open-faced samples had good uniformity in the filter no matter how many middles were used, but not so good for the closed-faced sampling. The calibration curve had a good correlation coefficient (r=0.995). Due to different industrial operating patterns, the distribution of crystalline free silica concentration varied by the industrial environment. The dust consisted of 10- 30% of crystalline free silica in all samples obtained from the foundry environments. The crystalline free silica was accounted for less than 10% in the respirable dusts.

结果显示，因为铝板对於结晶型游离二氧化矽具有较良好的补正系数，因此做为本研究的基底标准吸收校正的校正元素；SKC铝制旋风分离器搭配开匣式滤纸匣於一阶中环、二阶中环、三阶中环均有良好之均匀度，反之，搭配闭匣式滤纸匣其均匀度均不佳；分析检量线具有良好线性关系(r=0.995)，因作业型态不同，作业环境会有不同的浓度分布，综观作业环境中可呼吸性结晶型游离二氧化矽之含量均小於10%以下，总粉尘结晶型游离二氧化矽之含量约为10 – 30%之中。
