摘要
通过对西北地区应用棕榈科植物进行园林绿化现状的调查分析,发现其存在应用种类少,配置形式单一等问题,提出园林设计要结合地区实际情况,合理利用棕榈科植物,注重日常养护管理,加快改良培育适宜西北地区的耐寒新品种,以期为棕榈科植物在西北地区的应用发展提供相应参考。
The hydrostatic testing machine of Germany Mannesmann and Japan Yamamoto is now widely used in the world,and its technology is more advanced. Through analysis and comparison several aspects of above two companies ' hydrostatic testing machine, including oil and water balance system, pipe end sealing mode, steel pipe transport mechanism and so on, the advantages and disadvantages of hydrostatic testing machine were obtained. The design concept and performance characteristics of above two companies' can provide reference for China domestic steel pipe hydrostatic testing machine manufacturer, also can provide reference basis of chooseing steel pipe hydrostatic testing machine for domestic steel pipe manufacturer.
