- However, the value of SEDD is far less than that of SEPD in very strongly weathered granite and greater than that in slightly weathered granite. 由此可知,在中等硬度的花岗岩中,用冲击凿碎比功来估计金刚石钻进比功才是合适的。
- According to the red-bed rock's embedment depth, thickness of the weathered zone and its mechanical strength, the zone of Hefei City's red-bed were made. 并提出把红层不良工程地质性质应用在合适的工程中,从而转化为有利条件。根据合肥红层的分布、埋深、风化带厚度、岩石的强度等特征对合肥市进行工程地质分区和岩体工程地质分区。
- When a volcano erupts, dust is blasted[3] high above the tropo here and may take weeks to be carried around the weather zone, so ca ot be washed out of the air by rain. 火山爆发时,尘埃被高高喷射入对流层以上的空间,需要几个星期才飘浮移至气象层,因而雨水无法将其从大气中冲走。
- Our product has strong weatherability and long-term storage. 我们的产品耐候性强,保存时间长。
- It is implied that the regional trends of strong weather variations may be different even when the regional mean temperatures coherently change. 这意味着即使区域性平均温度变化一致,区域性强天气波动的变化趋势也会有所不同。
- Based on the discussion of hydrogeological condition of the fouth aquifer of Cenozoic Erath-em and the weathered zone of bedrock in Linhuan mining area, the cause of shaft wall damage is analysed. 本文着重讨论了临涣矿区新生界松散层中第四含水层(以下简称四含)及其下基岩风化带的水文地质条件.
- Strong weathering occurs in the fault zone, in which the fault breccias present in loosed soil like and was tinted into tawny color by ferrous leaching. 断层带风化强烈,断层角砾岩等呈现松散的土状,且因铁质琳滤而成黄褐色。
- Based on gas content analysis results the scope of weathered zones is determined. 通过煤层气样的气体组分分析,确定了甲烷风化带的大致影响范围。
- The boat heeled over in a strong wind. 船在强风吹袭下倾侧了。
- In paleo-granulite area, the rock mass is strongly weathered to great depths, but the weathering depths are quite different anywhere, on the surface, it mainly appears in loose state. 古老变粒岩地区,岩体风化剧烈、风化深度大且各处风化深度差异极大,地表多呈散砂粒状,该文对其在水利水电工程地质勘察中遇到问题进行了深入研究,初步掌握了古老变粒岩区岩体风化规
- With advanced production process stable quality, strong weatherability, long-term storage. 生产工艺高,品质稳定,耐候性强,保存时间长。
- The main ore deposit and the east ore deposit underwent strong weathering and denudation, and alluvial enrichment occured since Cenozoic era. 主、东矿床新生代以来经受了强烈风化剥蚀 ;并有冲积富集现象 .
