flat deposit造句
例句与造句
- the researches of dynamic behavior and liquefaction potential of saturated sands have been further . however, more and more macroscopic liquefaction phenomena and experimental investigations show that different depositional environments lead to different structure of soils, while the influence of structure property of soils on liquefaction resistance is no less than that of density and consolidation stress and so on . ancient alluvial flat deposits, namely recently deposited soils, are easier liquefaction during earthquake
对于一般饱和砂土的动力特性和液化势的研究已比较深入，然而，愈益增多的宏观现象和试验研究表明，由于土的沉积环境不同而导致土的结构性的差异，而土的结构性对抗液化能力的影响并不亚于密度、固结压力等因素，古河漫滩堆积物即新近沉积土在地震当中更容易液化。 - in this field observation we also find an important fact that, even during storm surge period, high tidal flat can still be in sedimentation in some place, no erosion occurred . to tell the typhoon storm surges from cold wave storm surges, 12 monthly sedimentary samples are collected from the modern tidal flat surface at dafeng, jiangsu . palynological analysis of these samples indicates that the seasonal palynological features of the tidal flat sediment are very obvious and some palynological indexes, such as taxon percentage of arboreal, herbaceous pollen and spore, are good indicators to tell the seasonality of the tidal flat deposits
为区分风暴潮沉积是由台风引致还是由寒流或冷锋引致，对长期处于淤积状态的江苏中部大丰县斗龙港附近潮滩，采集了一年中每月小潮期间滩面表层泥样，并在启东茅家港滩面分别采集了6月、9月与12月的表层泥样，在实验室中，对这些样品进行孢粉等分析，认为在以粉砂、泥为主的潮滩沉积中，孢粉种类百分比，尤其是木本种类占孢粉总种类的百分比是判别季节性潮滩的重要指标，通过启东茅家港工程建设区淤积状况的观测记录对这一判别指标进行了验证。 - It's difficult to find flat deposit in a sentence. 用flat deposit造句挺难的
