Phased array radars have been identified as the " next generation " radars for many applications and demonstrator systems have been produced over the last few years for naval , ground based , airborne and civil applications . great changes have taken place in digital technique at the same time 近年来，相控阵雷达技术逐步在众多科技研究领域表现出旺盛的生命力，并已经广泛应用到军用和民用领域；同时，数字技术也取得了迅猛的发展。
Through a comparison between several treatment methods such as drainage consolidation , powder spraying , pressure mud pumping , gyratory spray pumping etc , the result shows that under suitable condition the application of gyratory spray pumping has some advantages such as short construction period , high ground base bearing force after treatment and less compressibility . it can guarantee structures to be built in due time and safety after completion . those results show that gyrayory spray pumping technology has good practicality inengineering 通过对排水固结法、粉喷法、压力注浆法、旋喷注浆法等几种应用处理方法的效果对比，表明旋喷注浆法处理地基在适宜的条件下应用，具有工期短、处理后地基承载力较高、压缩性较小的优点，能保证构造物按期施工及其建成后的安全使用，只有较高的实际应用价值。
The ground base of the newly added chute in 4 tailings reservoir at dexing copper mine is characterised by thick weathered layer , loose structure , fractured zone and landslip mass accumulation . as a result , the ground has a great subsidence and inefficient carrying capacity . in view of this , the grouting technology was adopted to reinforce the chute ground base . the on - site testing shows that the subsidence of the chute has been efficiently controlled and the carrying capacity of the ground base improved so that the stability requirement has been met 浅地表赋存小矿体开采是矿山生产的有效补充,通过对潘洛铁矿洛阳矿区浅部零星小矿体开采现状分析,从加强开采技术,生产管理角度提出了自己看法.主要应加强小矿体的勘查工作,以及开采的总体规划,统筹管理,实现浅地表赋存小矿体的安全高效回采
