According to a Science and Technology Daily's Sunday report, China has discovered and named a new mineral, Wusihe germanium ore, with an average germanium oxide content of up to 72 percent, second only to germanite.
The mineral was jointly discovered, named, and submitted for approval by multiple Chinese research teams, and has officially been approved by the Commission on New Minerals, Nomenclature and Classification (CNMNC) of the International Mineralogical Association (IMA).
As a scarce strategic critical metal, germanium is an indispensable material in high-tech fields including modern semiconductors, fiber-optic communications, infrared optics, solar cells, and aerospace measurement and control systems. 
Due to its low abundance in the Earth's crust and difficulty in forming independent deposits, germanium has long been mainly produced as an associated element from lead-zinc ores and coal deposits, according to the report.
The mineral also marks the third germanium-rich mineral discovered in the mining area, the report said.
According to data released by China's Ministry of Natural Resources on April 29, China ranks first globally in reserves of 14 minerals, including germanium.

。    8月26日消息，据人民日报报道，最近，旅客冯女士的遭遇引起不少网友关注。    她在线上平台花6000多元订机票，误将出发日期选错，订票1小时左右申请退票，商家几乎扣除全部机票费，只退了600元保险费。     据黑猫投诉平台7月发布的报告显示，仅今年上半年，平台就收到关于机场航空公司的投诉近2.7万件，其中“退改费用高”投诉超1.3万件，占比接近一半。    报告还提到，消费者普遍反映提前7天以上甚至十几天申请退票，仍被平台扣除超过40%甚至90%的票款作为手续费。     而针对旅客关注的机票退改服务痛点，中国航协已牵头统筹推进机票退改服务升级优化工作，推出多项举措。

B |     研究出台退改标准，全面提升规则透明度，中国航协正在牵头制定机票退改专项团体标准，计划今年内正式发布实施。     标准将明确退改要求，所有售票平台、航空公司官方渠道，必须通过醒目字体、弹窗强制提示、专属标识、前置告知等方式，在旅客支付订单前主动公示退改费率、限制条件、免费退改场景，解决规则隐蔽、看不懂、不知情的问题，保障旅客知情权、选择权。    近日，东航率先调整国内客票退改规则，明确自8月6日（含）起销售的国内客票，所有舱位均可在航班离站前14天以上免费自愿退票、变更，打破了折扣票不可免费退改的传统限制。     针对一线客服、票务代理、线上平台工作人员开展常态化专项培训，规范退改规则解读、纠纷处置流程等工作。
