日本发明可将数据保存3亿年新技术 作者:邢熠  来源:日本新华侨报网 日本科研人员研究出一种新型存储设备,可将数据保存长达 3亿年。虽然还不知道将数据保存3亿年的现实意义,但这项技术却是一大突破。 据日本《朝日新闻》消息, 9月26日,日本京都大学与日立公司联合宣布,研究团队 发明了一项数据存储新技术,以石英玻璃作为记录载体,可达到与CD相同质量的存储效果。且数据存储的年限可超过3亿年,适用于长期保存重要的资料档案等。 据悉,这项新技术是用激光在厚2毫米、边长2厘米的方形石英玻璃板上刻录数据,数据记录层共分4层,存储容量有了大幅提高。研究团队计划用它记录人类基因组的数据。 实验数据显示,这种石英玻璃载体即使在1000摄氏度的高温下加热2小时,仍能保证数据被光学显微镜完整读取,显示其耐久性非常高。在理想状况下,人们常用的磁能及光盘等光存储媒体都只能将数据保存数十年至数百年,而这种石英玻璃载体的存储年限可达3亿年。

陆欣义母亲在英国一次围棋锦标赛之前发言纪念陆欣义(双语版)
热度 3 Wuyishan 2012-1-27 22:21
2012年1月21号, 由英国围棋协会主办、日立公司支持、梅登黑德围棋俱乐部承办的梅登黑德日立围棋锦标赛在位于梅登黑德的日立公司举行。来自英国的50多位围棋段位选手和围棋爱好者参加了比赛。比赛前, 举行了纪念陆欣义的仪式。 陆欣义父母应邀参加了纪念仪式, 欣义的母亲在仪式上发言: 亲爱的朋友们, 我很感谢梅登黑德围棋俱乐部、梅登黑德日立围棋锦标赛安排了纪念欣义的仪式, 我们也感谢英国围棋协会命名英国互联网个人联赛奖项为"陆欣义奖"。 这个地点让我回想起我和欣义当年初到梅登黑德的许多事情。我17年前被这个大楼内的日立欧洲微系统公司聘用, 从爱丁堡搬到梅登黑德。从那时起, 我们一直居住在梅登黑德。 在这里, 欣义上了小学、上了中学, 同时也学会了围棋。 十多年来, 欣义的许多星期五晚上都用于参加梅登黑德围棋俱乐部的活动。欣义也参加和组织了以前的梅登黑德日立围棋锦标赛。今天如果他没有出事的话, 也应该在这里和大家在一起。 围棋是欣义最喜欢的活动, 不仅享受着竞赛, 而且广交朋友。 欣义遇难后, 他的许多朋友给我们写信、或在网上撰文纪念他。最常听到的一个描述是":欣义的微笑"(Xinyi's smile)。 欣义是一个温和、友善、助人为乐的人, 他总是以真诚的微笑面对别人、面对生活。 他的微笑源于他喜欢围棋、也喜欢下围棋的人; 他的微笑源于他热爱所居住的梅登黑德、也热爱这个国家。他的微笑也给予了他的病人和同事, 也体现在他所参加的其它公益事业之中。我们为他而骄傲、为失去他而痛惜, 但是他的微笑永远伴随着我们。 希望欣义的朋友们记住":Xinyi's smile" , 祝愿梅登黑德日立围棋锦标赛成功举办! 该讲话原文如下: Dear friends: I am grateful to Maidenhead Go club, Maidenhead Hitachi GO tournament Mr. Iain Attwell for arranging such a memorial event for Xinyi. We are also grateful to the BGA League Tournaments for the naming of the Internet individual League winner prize as Xinyi Lu Prize. This building reminds me of many things about myself and Xinyi. I was employed by Hitachi Micro Systems Europe, just inside this building, 17 years ago when we moved from Edinburgh to Maidenhead. Since then, we have been residents of Maidenhead, where Xinyi completed his primary education, at All Saints School, and secondary education at Burnham Grammar School. Meanwhile, Xinyi learnt to play Go. For almost ten years, Xinyi spent most Friday evenings with Iain friends of Maidenhead Go club. Xinyi also took part in, and organized, previous Maidenhead Hitachi GO tournaments. Xinyi would have been here today if the accident had not occurred. Go was Xinyi's most joyful activity. Not only did he enjoy the game, but also he made so many friends through it. After Xinyi's death, many of his friends wrote to us, or, wrote on the internet in memory of him. The most frequently used expression is "Xinyi's smile". He smiled because he loved Go. He smiled because he loved those friends. He smiled because he liked Maidenhead and this country. His smiles were also there when he was with his patients and colleagues, as well as in other social activities. He had been a regular blood donor from when he was 18 until his death. He also became a registered donor so that he could contribute his organs and bone marrow in order to save other people's lives. He was a gentle, caring and kind person, so he always smiled. We are so proud of him and we feel very sad to lose him. But his smile will be with us forever. It has been so difficult during the past three months, when we fought a campaign in China in search of justice for Xinyi, and to raise awareness for the safety standards of public places in China. The local authorities have finally admitted their responsibility for the dangerous spot in the national park, and I am glad to say that it is now closed. We appreciate the strong support we have received from all of you. Thank you. Finally, we hope that all of his friends remember Xinyi's smile, and we wish today’s tournament will be a great success. 下面是英国围棋协会副主席约翰.柯林斯在英国梅登黑德日立围棋锦标赛前纪念欣义的发言 2012年1月21日 We know that everyone in the British Go community and Xinyi’s place of work was totally shocked and horrified to learn of Xinyi’s tragic death in October, whilst on holiday in China. As well as playing a prominent part in over-the-board games and tournaments, Xinyi Lu was an enthusiastic player in the newly-started online individual league during 2011 after playing a prominent part in the team league on behalf of the Central London Go Club team. Although he started in division 2, he soon dominated the division, not only playing more games than anyone else, but winning all of the ones he played. By August his position at the head of the division was unassailable and his promotion to Division 1 seemed inevitable – but alas it was not to be. It had already been decided that prizes should be awarded to the winner in each division of the Individual online League, but as a small memorial to Xinyi, it has been agreed that these prizes should be henceforth known as the "Xinyi Lu Prizes" as a small, but hopefully lasting, memorial to him. The other winners of the Xinyi Lu Prizes for 2011, who would have included Xinyi himself, have agreed to donate the value of their prizes to Xinyi's parents to assist towards their legal and other expenses in connection with his death. Whilst any such gesture can only seem totally inadequate in the face of the pain suffered by Xinyi’s family, we hope that the knowledge that his contributions to British Go were greatly valued and appreciated will give Xinyi’s family a justified sense of pride as they remember and continue to grieve for him.
