decreasing amplitude meaning in English
降幅
Examples
- This results in a decreasing amplitude in the first case and constant amplitude in the second .
在第一种情况下，它导致振幅递减；在第二种情况下，振幅不变。 - For the walls poured by ordinary concrete , the emm and ttm obtain the same qualitative conclusion , despite of some discrepancies in the specific value . but for the walls poured by the scc , the restraining stress calculated by the emm is remarkably smaller than that by the ttm . in other words , the emm results shows that the shrinkage compensation technology can take place the measures of setting dilatation joints , while the ttm results indicates that , though the restraining stress is decreased , the decreased amplitude is inadequate
对计算结果的比较和分析表明，对普通混凝土墙，结果的具体数值有差异，但反映的定性规律相同；对补偿收缩混凝土墙，结果差异巨大，等效模量法认为补偿收缩技术可实现无缝设计，而时程方法在承认补偿收缩技术可减小约束应力的同时，认为应力减幅还不足以实现无缝设计。 - The study shows that rock stress sensitivity has the following characteristics : rock property has little sensitivity to stress , of which porosity has the least , permeability less , and compression coefficient most ; the rock property decreases with formation pressure decrease ; in the same formation pressure drop , decrease amplitude of the rock property is not a continuous function of permeability but related to distribution scope of permeability
研究得出，岩石的应力敏感性特征主要有：岩石物性对应力的敏感性总体上不大，其中以孔隙度最小，渗透率次之，压缩系数最大；岩石物性随地层压力的下降而下降；在同一地层压降下，岩石物性下降幅度不是渗透率的连续函数，而是与渗透率分布范围有关，高渗透率范围，岩石物性下降幅度小，低渗透率范围，岩石物性下降幅度大。
