) opens to researchers around the world.

Sharing its advanced scientific facilities and platforms with the world is a kind of soft power that China has been gaining slowly. Other examples including the space station, the FAST radio telescope, Jiangmen Underground Neutrino Observatory, to name just a few.

不久前,中核集团原子能院宣布,他们研制的科学大装置中国先进研究堆实验平台全面对外开放,向全世界征集实验需求。先进研究堆是利用核反应堆产生的中子来做科学研究的。到目前为止,该平台已经收到了四十多个申请,项目涉及航空航天、材料、石油等科技前沿领域。先进研究堆能用来做哪些研究呢?

记者来到位于北京房山的先进研究堆这一天,正赶上研究堆开堆运行。进入正在运行的反应堆会不会受到辐射?在物理实验大厅,记者现场测量后发现,辐射量始终维持在0.6微西弗以下。按照这个数据,工作1400天的辐射剂量,相当于去医院做一次CT检查。

这里正在进行的研究有航空发动机叶片、高铁的车轮检测,甚至还有西汉的文物。

中核集团首席专家 陈东风:咱们国家这个堆,可能还要面向国家重大需求,解决我们国家的核工业、航天、航空和能源、交通领域的一些问题。

不同于核电站利用反应堆来发电,先进研究堆,是利用核反应堆产生的中子专门来做科学研究。

中核集团原子能院研究员 郝丽杰:中子穿透性非常强,它就犹如孙悟空的火眼金睛,可以透过金属材料、非常厚重的材料去看见内部的缺陷,这些都是其他射线难以做到的。

先进研究堆于2010年建成。去年,中核集团原子能院对它进行了改造提升,以便全面开放以后更好地服务用户。

中核集团原子能院党委书记 薛小刚:我们今年的目标是要运行100天以上,在2024年我们力争运行在200到250天以上。欢迎国际朋友,到我们平台上来做科研工作,共同开创一些新的领域。

服务国家重大工程 助力高质量发展

到目前为止,该平台已经收到了四十多个申请,项目涉及航空航天、材料、石油等科技前沿领域。而在先进研究堆建成后的13年中,已经面向国内50多家科研院所和大学进行了有限的开放。它的主要技术指标中子通量是亚洲第一,世界排名第三。中子通量越大,在实验中检测速度就越快,对检验的物品也会看得更清楚。这13年中,中子的“火眼金睛”看到了什么?又解决了什么问题呢?

这个高铁车轮已经跑了100万公里。但是在运行过程中,残余应力会导致金属疲劳、车轮破损。研究车轮残余应力,过去常用切割法和X射线检测。通过切割对车轮进行解剖,获取局部残余应力水平。但车轮破坏后就不能用了。X射线检测,只能对表面薄薄的微米层残余应力进行测试。而利用反应堆的中子,可以提前发现车轮的金属疲劳,预防安全事故。

中核集团原子能院高级工程师 李玉庆:我们可以不用破坏整个轮子,然后测到深度大概40毫米距离的深部的应力的分布。中子最大的特点就是无损检测。

通过中子检测,原子能院团队在国内首次完成了国产高铁车轮残余应力实验。这次,获取到了关系高铁运行安全、性能评价的关键数据。

中国工程院院士 王海舟:信息采集完以后,对于高铁车轮服役状况的预测、对于将来延长使用寿命都有很好的作用。对车轮将来结构的设计,以及车轮的整个成分组织结构的改进都会有很好的作用。

面向未来,先进研究堆在科技前沿领域还大有可为。因为中子射线对蛋白质几乎没有损伤,科学家们正在利用中子,研发一种治疗手足口病的药物。此外,中子还在新材料领域大显身手。借助中子,科研人员能看清粉末状的电池材料内部的原子是如何分布的,通过研究来改善钠离子电池的续航和快充性能。

中国科学院院士 张焕乔:我们国家投资了10亿人民币建造了这个高中子通量的先进反应堆,同时又在反应堆上投资了5亿多人民币,建成了15台先进中子谱仪。这个装置在国际上应该说是具有很强竞争能力的中子科学平台,所以应该得到充分的应用。我相信这些谱仪的利用能够在多学科取得巨大的成就。

中子“拍照”后形成玫瑰花影像

一朵玫瑰花,很多人不陌生,而通过中子的“火眼金睛”,我们看到的可能是不一样的花朵。

中子“拍照”后形成的玫瑰花影像,能看到花瓣上细微分布的脉络,更深层次领略自然的神奇。正是因为中子有穿透性强的本领,它们也被用到更多的领域,比如给文物“拍照”,帮助专家精准修复文物。

中子成像助力文物修复

汉代,人们习惯于席地而坐,席子也是古人常用的生活用具。席子不仅容易卷边,起身时还会移动,因此席镇应运而生。北京大学考古文博学院在准备修复这个文物时,就遇到了难题。文物被这些含铜的腐蚀物覆盖了,看不出它本来的样子。于是,他们委托贺林峰团队对席镇进行中子成像。

北京大学考古文博学院副教授 胡钢:当时的制作工艺是怎么样一个过程,我们特别想知道。我们在保护修复过程中,每一个细微的环节,如果操作不当,有可能把它的信息给破坏或者改变。

中子成像后,贺林峰团队通过影像学,去除了表面的腐蚀层,这件2000多年前的文物露出了它原本的面貌。镀银的纹饰、羽毛的纹路、动物的造型栩栩如生。

北京大学考古文博学院副教授 胡钢:中子成像的结果明确显示,下面应该是用了某一些胶结材料把它进行有效的固定,这个很有意义,在保护修复当中我们就可以更好注意。从科技价值认识来说,我们能够更好地把这件器物的制作工艺呈现出来。

下一步,北京大学考古文博学院还将利用先进研究堆,对“南海一号”沉船上的铁器、陶瓷碎片进行中子成像,找出这些在海洋底下浸泡了800多年的铁器、瓷器内部的锈蚀点,以利于更好地修复文物。

中核集团原子能院研究员 贺林峰:我们每天都可以碰到不同的用户,会讲他们不同的科研故事,这个对我们来说是一个非常兴奋、非常有意思的事。实际上每一个对象对我们来说都是一个盲盒,永远不知道有什么新的发现。

The critics, their old gen films.
They always make the same things over and over again.
That's what you get for outsourcing the production of arts to the degenerate capitalist class instead of keeping government control, just because in the days of Mao, things went "too fast and too hard" in the opinion of some pro-western "thinkers"(read:brainlets).

Endless squabbling over whether it is appropriate or not to have frontal sex in tv series, constant "artsy" and other purposeless content.

American entertainment media is a case of succesful government control in the past, now become a failure because the government's values do not align with what most consider good taste. Chinese entertainment media is an example where no attempt to even control was made, thus causing the control to automatically go to the feeble minded in the movie industry.

Movies should entertain but also inspire awe for the socialist system, promote Chinese values globally, suppress and ridicule the values of the enemy. These are the only things that should need to have quotas, any "critic" or "politician" saying something else is either feeble minded or willingly a traitor trying to obfuscate Chinese media.

For this view, I believe that too much hope should not be placed on the government propaganda departments that have become severely rigid and detached from the masses.
Last month's official media caused a series of serious publicity disasters, in this extremely harsh environment where workers are treated, they are still promoting the disgusting success myth of "work hard, the days will become sweeter".

Among the youth community, films such as "The Second Spring/第二个春天" and "Break/决裂" shot in 1975 suddenly regained popularity.
These films are a summary of the theoretical thought of "continuing revolution", which severely criticized the elitism tendency of intellectuals and bourgeois ideology in the educational policy.
However, nowadays, the erroneous ideas of education corruption, detachment from reality, superstition in authority, and bureaucracy that were once severely criticized still exist and are even more serious.
The most ironic thing is that the two films I mentioned suffered a comprehensive political rejection after the end of the Cultural Revolution.

I would like to put it bluntly: the current government favors social elites who can provide taxes. They are no longer able to empathize with workers, so what you see now are arrogant and annoying propaganda slogans, as well as "experts" who make shameless remarks for interest groups.

How do you think it would be better for the government to intervene more? What else would they do besides issuing various unpleasant bans?
Why are there so many absurd soap operas about the Anti Japanese War? Because of political correctness, this is the only subject with loose inspection standards, so all film and television workers choose to shoot this "safe" subject, and put those subjects that are restricted to shooting into it.
This is the result of what you imagine as' government intervention '. At present, their management ability is completely inadequate for the "guidance direction" you imagine.
