查询词典 porpoises

My thought when I saw the huge pits with facilities for intake and outtake of ocean water is that they could be the center of a large marine park with killer whales and porpoises, or a whale research center, complementing the nearby fishing port and beaches, which are among the few beautiful and safe beaches on Taiwan's long coastline.

当看到那些已装设抽取海水设备的巨大水泥建筑物时，我的想法是这里可以成为有虎鲸、海豚的海洋公园或鲸鱼研究中心，正好和附近的渔港、以及台湾少数美丽且安全的海滩形成互补。

Diving behavior and echolocation pulse rate of three captive porpoises in Wuhan Baiji Dolphinarium were observed continuously using both behavioral and acoustic data loggers on 23?25 November 2002. A total of 38 hr of behavioral data and 40 hr of acoustic data were recorded for each porpoise.

同时使用行为和声学微型生物跟踪记录仪，于2002 年11 月23-25日，跟踪记录了白鱀豚馆3 头江豚的行为和发声，每头江豚行为记录时间38 hr，声学记录时间40hr。

According to our present broadcasting situation,the thesis proposes using new technology to update and reform the present HFC. It also suggests broadcasting using self-advantage and arranging EPON in order to win the supermarket.

论文从我国广电的现状出发，结合实际，积极倡导采用新技术更新、改造我国现有的HFC网络；倡导广电现阶段利用自身优势，部署EPON网络来赢取市场。

A new general kinetic equation was derived in which the effect of the removal of condensation water was taken into account completely, and was applied to the polyesterification kinetic study of AA/HPHP and AA/NPG. It was found that the reaction order of self-catalyzed polyesterification was not constant. For these polyesterifications, the reaction order was 2.5 at a low temperature, while 3.0 at a high temperature.

考虑缩合水的排除对反应体系的影响，用体积浓度单位推导出一个新的聚酯反应总包动力学方程，并应用到AA/HPHP和AA/NPG两个聚酯化反应的动力学研究中，研究发现，自催化聚酯反应的反应级数并不是固定值，对于AA/HPHP和AA/NPG两个聚酯化反应而言，低温时反应级数为2.5，高温时反应级数为3.0。
