, 2006 本实用新型涉及防水材料，具体说是一种管孔止水条。在现有技术中，在混凝土现浇渠道过程中，混凝土预制渠道间的伸缩缝是通过止水条来防止水的渗漏，现有的止水条的结构为实心的条状物，其材料采用橡胶、塑料等防水材料，所以其弹性较差，而且材料的成本较高。本实用新型在原有的止水条基材的内部至少设置一根弹性管，其外表面轮廓为圆形、方形、梯形或X形等，适应缝隙的形状。因而本实用新型节省材料，降低成本，孔适应外界变形能力强 ...

, 2008 通过对西安周边地区11个采样点饮用水中砷含量的调查分析,结果表明西安南部秦岭地区和西安东部的饮用水中砷含量较低,西安西部户县地区砷的含量明显高于其他地区,达到了0.047mg/L,已基本上接近了轻度污染的标准。综合分析认为,造成这一地区砷相对富集的原因并非单一因素,而是自然因素和人为因素综合作用的结果。户县地区地处秦岭造山带,位于商丹断裂带以北,岩浆侵入体和金矿床的存在可能是高砷环境的主要原生物源。位于商丹断裂带以南的镇安地区同样岩浆侵入体普遍存在,岩石地层中砷含量相对较高 ...
