It concludes that without any information or interference from the author, the story plainly replays a real-life scene. While at the same time, it conveys thought-provoking themes such as the loneliness, nothingness and dignity in life.展开更多
按照鱼类寄生虫调查及研究方法,对额尔齐斯河(中国段)东方欧鳊(Abramis brama orientalis Berg)寄生虫种类及感染情况进行了调查研究。结果检出寄生虫8种:对盲囊线虫、复口吸虫、温氏指环虫、宽头鲤蠢绦虫、奇怪双身虫、复殖吸虫幼虫、...按照鱼类寄生虫调查及研究方法,对额尔齐斯河(中国段)东方欧鳊(Abramis brama orientalis Berg)寄生虫种类及感染情况进行了调查研究。结果检出寄生虫8种:对盲囊线虫、复口吸虫、温氏指环虫、宽头鲤蠢绦虫、奇怪双身虫、复殖吸虫幼虫、泡吻棘头虫和毛细线虫。感染率分别达43.75%,37.5%,18.75%,18.75%,14.58%,12.5%,8.33%,2.08%。奇怪双身虫经检索鉴定,为我国单殖吸虫纲铗钩虫目双身虫科的一属、种新记录。展开更多
