Concrete components have flaws, such as loose, hole, slit band and so on. These flaws not only lead to the change of acoustic velocity, but also have strong absorption and attenuation action to the acoustic wave. It is an effective method to detect engineering quality of concrete components by using acoustic velocity CT and attenuation CT combined detection technology.

混凝土构件中存在的诸如松散、空洞、缝隙夹层等缺陷，不仅造成声波速度的变化，而且对声波具有较强的吸收衰减作用，利用声波速度CT和衰减CT联合检测技术是检测混凝土构件工程质量的有效方法。

Based on the detailed analysis of existing dimension recognition methods, this paper concluded a common limitation of existing methods-"single-entry recognition", which has three distinct drawbacks. First, the only recognition entry reduces the capability to handle drawings of different qualities; second, the fixed search order for dimension elements block algorithm seeking all possible ways to find a dimension structure; third, single directional recognition of graphic elements uses no drawing context and thus can not make use of engineering knowledge.

本文分析了现有的尺寸识别方法，指出它们共有的局限性——单入口的识别过程：单一的识别入口限制了算法对不同质量图纸的适应能力；固定的元素搜索顺序阻碍了算法利用一切可能的途径寻找和识别尺寸标识结构；单向的独立于上下文的图形元素识别忽略了应用领域知识对识别过程的启发作用。

With the action of leaching by rain and water and self-combustion , some hazardous trace elements and harmful organic materials will be dissolved completely or partly and move out from coal mining waster into water, soil and gas.

大量的煤矸石在雨水和地表水的淋溶以及自燃等自然条件作用下，一些有害微量元素能够溶解、挥发出来进入水体、土壤环境和大气环境，从而造成水体质量下降、土壤功能被破坏、大气污染，并由此对生态发展和人体健康有严重的影响。

The results show that, the nitrate-N concentration in groundwater in the reed area was 0.2~0.8mg/L and significantly lower than that in surrounding wells (more than 20mg/L), and the reed wetland can remove nitrate pollution in shallow groundwater. The distribution of denitrifying bacteria showed obvious rhizosphere effect, and the higher biodenitrification in natural reed wetland was related to the distribution of denitrifying bacteria. There was a negative relationship between the nitrate-N concentration and the number of denitrifying bacteria in groundwater.

结果表明：芦苇区浅层地下水中硝酸盐氮仅为0.2~0.8mg/L，远低于湿地周围井水中硝酸盐氮质量浓度（大于20mg/L），芦苇湿地能够去除浅层地下水中硝酸盐污染；反硝化细菌在土壤中的分布呈现明显的根际效应；野生芦苇湿地较强的生物脱氮作用与反硝化细菌分布有关，地下水中硝酸盐氮含量与反硝化细菌分布呈负相关。

Thus, it can be seen, this research"s main innovation includes: constructing and validating the "Customer Churn Intention"s Influential Factors Model based on Credit Card Market"; disconfirming subjective norms" direct influential effect on customer churn intention; and developing credit card service quality"s dimensions and measurement scales.

本研究的主要创新之处主要在于：构建并证实了基于信用卡市场的客户流失倾向影响因素模型；证伪了主观规范对客户流失倾向的直接影响作用；并总结出了信用卡服务质量的构成维度及测量量表。
