查询技巧:
1、输入单个单词准确查询。
2、使用%模糊查询,匹配任意长度字符:
   %a    以a结尾的单词;
   ab%    以ab开头的单词;
   %ac%    含有ac的单词。
3、使用_模糊查询,匹配单个任意字符:
   _a_    三位且a在中间的单词;
   _ad    三位且ad结尾的单词;
   ac_    三位且ac开头的单词;
   _a    两位且a结尾的单词;
   a_    两位且a开头的单词。
4、带连字符-的单词,需含-字符才能模糊查询,如well-know需输入 well-% 。
5、在手机键盘上,如果g上有%和v上有_,则可长按输入。

sedimentation
GRE

英 / ˌsedɪmenˈteɪʃn /
美 / ˌsedɪmenˈteɪʃn /
n. 沉积(过程)

1. Effluent from the sedimentation tank is dosed with disinfectant to kill any harmful organisms.
从沉降池流出的废水被加入消毒剂以杀死一切有害生物。
2. In all these diverse regions, Agassiz saw signs of glacial erosion and sedimentation.
在这些不同的地区,Agassiz 都能发现冰川侵蚀和沉降的痕迹。
3. Unfortunately, such estimates did not adequately account for past differences in rates of sedimentation or losses to the total section of strata during episodes of erosion.
不幸的是,这种估测没有充分考虑到过去在侵蚀期间沉积速率或地层总剖面损失的差异。
4. By contrast, because sedimentation is much less continuous in continental regions, estimating the age of a continental bed from the known ages of beds above and below is more risky.
相比之下,由于沉积作用在大陆地区的连续性要小得多,因此根据已知的上下岩层的年龄来估计一个大陆岩层的年龄风险更大。
5. Sun clocks worked, of course, only on clear days; water clocks misbehaved when the temperature fell toward freezing, to say nothing of long-run drift as the result of sedimentation and clogging.
当然,太阳时钟只能在晴天工作;当温度下降到接近冰点时,水钟就会失灵,长期漂浮的东西因为下沉或堵塞而无法工作。
