In addition, the crusher boasts of a large reduction ratio, few equipment, power saving, low cost and being small.

研制的ＰＥＷＤ４０７５型大破碎比颚式破碎机，经过工业试验和近一年的生产实践证明，该破碎机的处理能力和破碎后的矿石粒度直接入磨及设备运转状态等技术参数均符合设计要求。

Comparing with the traditional patching method of using small plates and L-bolt with the help of chain hoist, this technique deploys a complete steel plate and chain block to patch a big hole underwater, which would reduce the workload of the divers, improve work efficiency, and ensure the structural strength as well as the water tightness after completion.

改变传统的弯钩螺丝加小件板勾连船体的封补工艺,以手拉葫芦提供拉合力,用整件大钢板封补水下大破洞,既减轻潜水员的工作量,提高工作效率,又保证封补后强度够,水密度佳。

2 and taking US Westinghouse corporation Surry nuclear power plant as the reference object, a typical three-loop pressurized water reactor severe accident calculation model was established and 25cm large break loss of coolant accident(LBLOCA)in cold and hot leg of primary loop induced core melt accident was analyzed.

2,以美国西屋公司Surry核电站为参考对象,建立了1个典型的3环路压水堆核电站的严重事故分析模型,分别对主回路冷段和热段发生25cm大破口失水事故(LBLOCA)导致的堆芯熔化事故进行研究分析。

The analysis of large break loss of coolant accident(LBLOCA) which occured at nominal power of nuclear power plant is given.

针对核电站额定运行工况下发生冷段大破口失水事故进行了分析。
