Historical Context of D/S Permit - The concept of "D/S" has evolved from early US immigration laws, which initially did not require formal registration for foreign nationals [3][7]. - Historical examples, such as Qian Xuesen, illustrate the complexities and bureaucratic challenges faced by international students in maintaining their legal status in the US [7][9]. Abuse of D/S Permit and Consequences of Trump's Policies - The article highlights that the D/S permit has been subject to abuse, allowing some students to remain in the US indefinitely by continuously enrolling in academic programs [11][12]. - The potential elimination of D/S could lead to a decline in international student enrollment, negatively impacting the financial health of US educational institutions [19][21]. Broader Implications for US Education and Research - The proposed changes to the D/S permit are seen as detrimental to the US education system, particularly for graduate programs that rely on international students [21][22]. - The article argues that the new policies could undermine the quality of doctoral education in the US, as students may face increased pressure to graduate within a limited timeframe [21][22].

本文来自微信公众号：学霸本霸（ID：yishen233），作者：为渣哥鼓掌的，题图来自：视觉中国 昨天渣哥去献血了。 咳咳，这还真不是文字游戏。 单看"失去400ml血液"这件事，通常是没啥危险的。一个健康成年人的总血量大约是体重的7%~8%，比如70公斤的渣哥，血量就是4900毫升， 所以，献出去的400ml，差不多占总血量的8%～10%。体质合格的健康人好好休息过后，是可以通过自身代偿机制逐渐恢复的。 然而！要说失血400ml，情况就大大不同了！ 要知道，平时手指割伤、轻微流鼻血，出血量基本不会超过10ml。 女生们来月经，一个礼拜的出血量大概也只是30~50ml。 或者不幸染上了胃溃疡等引起消化道出血的疾病。再或者，发生了产后出血，难产等妇产科意外，那你大概率会失血400~1500ml。 随着失血量的增加，你可能面色发白、手脚冰凉，还会口渴、心动过速。 失血时口渴，是因为血容量减少引起交感神经兴奋，进而产生口干的感觉，但此时身体正忙着自行调整，让剩下的血优先供应重要器官，如果 这时候猛喝水，血液被稀释，血压将更低，加速休克！ 2 能伤到失血400ml的程度，要面临的情况，大概率不止丧失400ml血液了。 ...
