中国第一个3D打印生物标本：世界上最后一只白海豚的完美复制_我的网站

A | 据1月13日《科学技术日报》官方微博报道，1月12日，湖北省武汉市中科院水产研究所展出了一只白鳍豚的3D打印标本。

B |     Tere Ishk Mein is turning out to be a major winner at the box office. The Anand L Rai film, led by Dhanush and Kriti Sanon, has matched the strong buzz it carried before release and is now steadily inching toward the Rs 100 crore net milestone in India.           Early estimates suggest the film earned around Rs 10.25 crore on its fifth day, with almost the entire chunk coming from the Hindi version. Tuesday’s numbers were a noticeable jump from Monday’s roughly Rs 8.25 crore, which had seen a sharp drop after the film hit its peak on Sunday with Rs 18.25 crore. With a solid opening weekend of about Rs 50 crore, the film has now reached an estimated Rs 71 crore net in India.     Its overall performance remains strong across the board. The movie’s all-India gross has touched about Rs 84.25 crore, while international markets have contributed another Rs 7.25 crore. This pushes the film’s global total to around Rs 91.5 crore in just five days, placing it in a comfortable position to recover its reported Rs 95 crore budget soon.          Day 5 also marks a milestone for Dhanush, as the film’s domestic gross has already overtaken the lifetime numbers of his 2013 hit Raanjhanaa. With Hindi net collections alone crossing the earlier film’s tally, Tere Ishk Mein has become his highest-grossing Hindi release within days. The film will now enter a competitive phase with Ranveer Singh’s Dhurandhar arriving this Friday, followed by the Hollywood release Avatar: Fire and Ash the week after.ALso Read: Paramvir Singh Cheema on Working With Kriti Sanon and Dhanush in Tere Ishk Mein。这是我国第一个三维印制生物标本。据报道，“齐琪”被认为是最后一只白海豚，在2002年被囚禁22年后死亡。3-D打印样本长2.07米，重约7公斤。它是从三维打印构建的“冰淇淋”三维数据模型中恢复出来的。据报道，“奇奇”是世界上最长的圈养海豚。

C | 1980年被渔民捕获并送往水生栖息地。自从2002年它死后，没有人见过活海豚。白鳍豚（学名：白鳍豚，lipotes vexillifer），又名：白鲸、白鳍、白旗、白夹、绿鳍、琵琶、中国鼠海豚、长江鼠海豚、长江河豚，是我国特有的淡水鲸种，只产于长江中下游。20世纪80年代，由于各种原因，海豚的数量急剧下降。2002年，据估计有不到50只海豚，被称为“水中大熊猫”。海豚属于自己的家族，被列为国家一级保护野生动物和世界上12种最濒危动物之一。2007年8月8日，一份报告发表在《英国皇家学会生物学快报》上，正式宣布了海豚的功能性灭绝。
