Chongqing's auto exports surge 57.1% in first seven months_我的网站

A | 北京时间1月16日消息，我们的太阳系有一颗恒星和八颗行星。但其他星系可能远不止这些，而且会有两三颗恒星围绕彼此运行。

Changan Automobile, Seres and Great Wall Motor are among the major automakers headquartered in or operating production bases in the city. Changan Automobile also reported strong growth in overseas deliveries, with 82,300 vehicles delivered overseas in August, up 79.1% year on year. Seres, meanwhile, launched its first dedicated cross-border freight train via the China-Laos Railway under the New International Land-Sea Trade Corridor in 2026, marking the first time Chongqing has used the route for a customized train carrying complete vehicles for export. "The globalization of China's automobile industry is in full swing," said Wang Hui, executive vice president of Changan Automobile. He noted that overseas market research has shown strong acceptance and recognition of Chinese auto brands. "We have seen strong demand for Chongqing-made vehicles in the Central Asian market this year, with more companies entering the automobile export business," said Liu Lei, a Chongqing-based auto export dealer. Chongqing has launched the "Yuche Chuhai" (Chongqing Automobiles Going Global) action plan to build a nationally leading export base for intelligent and new energy vehicles (NEVs). The plan aims to increase the city's annual NEV exports to more than 120 billion yuan by 2027. (By Tang Yuxian) 。这个星系被命名为HD98800。

C | 天文学家利用智利的阿塔卡马大毫米阵列射电望远镜发现了它。射电望远镜是发现这个星系的关键，因为这些恒星被原行星盘所包围。据报道，最初的行星盘是指在行星形成之前出现在早期星系中的尘埃和气体环。

D | 最终，尘埃和气体会坍缩成行星，但在此之前，圆盘将阻止大部分光从星系中逃逸。

E | 然而，无线电波可以穿透灰尘。基于这一原理，科学家们利用射电望远镜在尘埃中发现了四颗独立的恒星。这四颗恒星形成了两对双星，一对在银河系的中心，另一对在数十亿英里外的轨道上。根据天文学家的说法，外对命名为aa和ab，而中心对命名为ba和bb。由四颗恒星组成的星系本身很奇怪，但真正让这个星系奇怪的是原行星盘。在大多数系统中，原始的行星盘与主星对齐。例如，在我们自己的太阳系中，所有的行星和小行星都在与太阳大致相同的平面上运动。HD98800的情况并非如此，它是一个由尘埃和气体组成的原行星盘，与中央恒星平面成直角。恒星系是人类发现的第一个具有这种垂直圆盘的双星系统，这表明宇宙中有许多未知现象等待发现。
