Easily migrate data to a partitioned database or warehouse using the splitter function to unload into pre-split files ready for parallel loading.
使用splitter功能将数据卸载到预分区文件来为并行加载做准备,轻松地将数据迁移到分区数据库或数据仓库。
Rather than splitting out new chunks one-by one, pre-split many at once.
不是逐一的分割出新块,而是一次预先分割出多个。
This paper presents a fracture mechanics model of smooth blasting and pre-split blasting, analyzes the function of stress waves and quasi-static pressure of explosion in blasting process.
本文提出了光面爆破和预裂爆破的断裂力学模型,分析了应力波、爆生气体准静态压力在爆破破裂过程中的作用。
It's the new improved technology of pre-split blast at present. The BHPO method is based on modern mechanics which could do better on slope protection.
BHPO预裂爆破方法是建立在现代力学的基础之上,可以更好的达到保护边坡的目的。
Results indicate that the residual stress is useful to form the cracks between the shot-holes for smooth blasting, but not for pre-split blasting.
结果为:原岩应力的存在有利于光面爆破的炮孔间贯通裂纹的形成,不利于预裂爆破的炮孔间贯通裂纹的形成。
