英语词汇dim spot怎么读，是什么意思，单词翻译、读音、固定搭配用法和短语词组及例句-英汉双解词典

单词	dim spot
释义	dim spot 简明释义地震暗点：地震暗点是指地震波属性在局部显示的低振幅异常，一般可指碳氢化合物的存在。起因是含碳氢化合物的砂岩其声阻抗比同层含水的声阻抗低的。如果在深层，上层被低声阻抗页岩覆盖，砂岩顶界反射系数在含碳氢化合物地区会减低。因而造成局部暗点。在浅部地层，页岩和砂岩声阻抗会交叉相反，反而造成亮点（bright spot）。网络释义 1 ?暗点 ... dilvar镍铁合金 dim spot暗点 dim.尺寸 ... 短语 1 dim spot reservoir 暗点型油藏 2 Dim-spot gas-bearing reservoirs 暗点双语例句 1 There should be a hide box located in the corner away from the basking spot to allow the animal a cooler dim retreat. 微暗的遮蔽处应远离热点来给予动物作休息和降温之用。
