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 |
China rejected on Friday an accusation by Philippines' Defense Secretary Gilberto Teodoro Jr. that China had used action against Filipinos to pressure the Philippines over its law enforcement operations against Chinese nationals, saying that foreign nationals in China should abide by Chinese laws and regulations.
In response to a question about Teodoro's claim that China's actions against 100 Filipinos are "simple extortion and blackmail," Guo said China's immigration authorities perform their duty in accordance with the law and protect the lawful rights and interests of the personnel concerned. The actions do not target any specific country.
It's learned that it was exactly this defense secretary who personally led the armed forces to seize and detain Chinese nationals lawfully working in the Philippines, Guo said.
This person's consistent attacks and smears against China harm not only the bilateral relations. It is the interests of the Philippines and all its people that will bear the brunt, the spokesperson added.
。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。这是我国第一个三维印制生物标本。
B | 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。
D | 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。
