Iranian FM condemns Biden's remarks on recent protests in Tehran_我的网站

一 |     杭州造出了可量产“超级冰箱”。2025年8月，杭州白马湖实验室造出了一台“超级冰箱”。在零下268.95摄氏度的液氦温区，这台脉管制冷机的制冷量达到了1.8到2瓦，降温时间稳定在45分钟左右。    Tehran, Oct 16 (UNI) Iranian Foreign Ministry spokesman Nasser Kanaani criticized US President Joe Biden for his remarks on the protests that swept across Iran after the death of 22-year-old Mahsa Amini and his comments about the country's leadership.
During his speech at Irvine Valley Community College in California on Saturday, Biden said that he was "stunned" by the wave of demonstrations in Iran, noting that the US stands with "the brave women of Iran."
"Ever since the recent events [protests and riots] in Iran, just as he did yesterday, on Saturday, US President Joe Biden yet again supported the unrest in Iran with his statements... Your habit [addressed to Biden] is to fish in troubled waters. But remember, this is Iran," Kanaani was quoted as saying by Iranian news agency ISNA.
The official noted that Tehran was not surprised by Washington's comments, while "aggression and interference in domestic affairs are inherent in US politics and lie at its core."
Mass protests started in Iran after the death of 22-year old Amini on September 16 after her detention by the controversial morality police over "improper" hijab wear. Over 40 people were reportedly killed and 100 others injured during violent demonstrations.
Tehran claimed that the unrest was instigated from abroad and handed notes of protest to the ambassadors of the United Kingdom and Norway, along with the French chargé d'affaires in connection with what Iran believes was propaganda of subversive, anti-Iranian messages in their media, as well as calls for a government coup in Iran.

二 | 这个温度，离绝对零度（零下273.15摄氏度）只差4.2开尔文，被称为现代前沿物理世界的“门槛温度”。今年5月，记者曾专访“超级冰箱”研发团队。这是国内首台采用单一气库技术路线、实现1.5瓦以上制冷量的脉管制冷机，近日，正式通过量产验证。怎么理解这台“超级冰箱”的原理？白马湖实验室氢能储运团队独立首席研究员方凯解释：气体被压缩的时候，会放热。

三 | 反过来，如果让高压气体“嘭”一下释放出来，猛地膨胀，它就会疯狂吸热，周围就会冷下来。

四 | 这就是“脉管制冷”技术。这台“超级冰箱”主要由压缩机、旋转阀和冷头三部分组成。今年3月，设备在实验室完成了性能验证，制冷量、降温速度、功耗等核心指标均达到国际先进水平，而成本只有进口设备的2/3。按照规划，一年可生产“超级冰箱”50至100台。

五 | 这台“超级冰箱”到底有什么用？在量子计算领域，它是量子比特安静计算的“绝对静室”。量子比特极其脆弱，任何一点热量干扰都会让它出错。极低温环境能让它摆脱热噪声，稳定地进行计算。在医疗领域，它是医用核磁共振成像设备的核心部件，让超导磁体稳如磐石。“没有这个温度环境，所有的高端应用，都是空中楼阁。”方凯说。

六 | 长期以来，脉管制冷技术和机器核心组件被国外垄断。这次突破，不仅打破了国外技术垄断和出口限制，更补上了能源科技与量子产业全国产化链条上的关键一环。
