A comprehensive analysis is done based on the data of sedimentary structure,sediment radioactive isotope age determination,comparison of historical sea chart together with duplicate measurement of profile depth in Maotou trough and the adjacent area.
对1995年采自三门湾猫头深潭及附近海域的原状土样的沉积结构、沉积速率的计算及在历史海图地形对比、剖面重复水深测量等结果进行了分析,研究了该区底床的冲淤演变及其动力机制,结果表明:强劲的水动力条件维持了三门湾猫头深潭及附近海域底床冲淤的动态平衡,近百年来该区冲淤平衡且略有淤积,平均沉积速率为1～3cm/a。
The identification and pretense of owl represents Lu Xun s rebellion against the traditional cultural concept.
作为鲁迅笔下重要的动物意象,猫头鹰可以说是鲁迅神形毕肖的自我形象标记。
Lu Xun s endearment to the owl is a reasonable and selected kind of affection: for one thing, the main characteristics of the owl are beneficial to reflect Lu Xun s thoughts, and for another, it is also a correction of the reversed attitude towards the value, implying Nietzschean thought of "the reevaluation of all the values".
