A groundbreaking ceremony for the China-aided upgrading and renovation project of Savannakhet Secondary School in southern Laos' Savannakhet province was held on Friday.
Representatives from government departments and enterprises of both China and Laos attended the ceremony and jointly laid the foundation stone for the project.
In his speech, Lao Deputy Minister of Education and Sports Kingmano Phommahaxay said that the project will significantly improve the educational infrastructure of Savannakhet Secondary School, providing students with a safer and more modern learning environment. He said the project is a fruitful outcome of efforts to build a China-Laos community with a shared future.
Li Xizhen, economic and commercial counselor at the Chinese Embassy in Laos, said the school is one of 10 schools in Laos aided by China. Upon completion, the project will provide students in Savannakhet province with a more advanced and modern learning environment, helping Laos cultivate more outstanding talent.
The upgrading and renovation project has a total construction area of approximately 6,000 square meters. It will include a modern teaching building, an office building, an indoor sports hall and related supporting teaching facilities, fundamentally improving the school's educational and operating conditions.

B |     在他们的观测中，天文学家注意到，这个“棉花糖”世界，正如许多人所认为的那样，似乎比我们之前探测到的任何其他气态巨行星的密度都要低得多。

C | 此外，它与它所环绕的红矮星的距离很近，这引起了关于该行星形成的更多问题。卡内基科学研究所地球和行星实验室的研究员Shubham Kanodia在NOIRLab共享的新闻稿中说：“传统上认为红矮星周围的巨行星很难形成。天文学家已经开始称这是一个‘棉花糖’世界，原因是这个气态巨行星具有与棉花糖相似的密度。”但是，这个气气态巨行星究竟是如何变成如此低的密度的，这让科学家们感到困惑。然而，他们已经为这个“棉花糖”世界的密度提出了至少一个可能的原因。而这个理由可能与该行星的岩石核心有关。据信，气态巨行星开始时是巨大的岩石核心，质量是地球的10倍。

D | 从那里，它们迅速拉入大量邻近的气体，形成我们今天所知道的“巨无霸”。

E | 其他的气态巨行星，如木星，甚至可能因吞噬其他行星而长到如此大。这颗被称为TOI-3757 b的行星有可能在其核心内有较低的重元素丰度，因此岩质核心形成得更慢，推迟了气体吸积的开始。

F | 未来对这个“棉花糖”世界的观察（也许用詹姆斯-韦伯太空望远镜）可以告诉我们更多关于它的大气和密度的信息。研究人员在《天文学杂志》上发表了一篇关于该行星的论文。
