The lay professor sighed, and then felt that he was stupid enough, they didn't even invent the ion accelerator mass spectrometer, and it was useless to think about it in advance.

These things are all interlinked and in the same vein. There are no preconditions, and it's useless to figure out the back.

The reason why he didn't expect it was just because it was useless to figure it out, so he didn't spend his brainpower in this direction at all.

"The afterlife is terrible, it's really terrifying. The Chinese are amazing, I didn't expect that with the high-energy physics foundation of our Dongda University, in the field of isotope separation, you are still superior in technology. The lay professor sighed convincingly.

Professor Yamashita Takehisa listened attentively for a while, and carefully confirmed: "In other words, this experimental data should be valid, and can it be used as the official conclusion of the dating of the 'Seal of the King of Han'?"

"No problem. The laity said with confidence.

The laity all recognized Gu Wan's instruments, experimental methods, and conclusions, and others naturally had no doubts.

For the rest of the day, under the joint witness of experts from many countries, the two sides also used the same technical means to determine the age of the "Seal of the King of Dian" and the "Seal of the King of Guangling" brought by the Chinese side for loan.

Gu Play's AMS completed the task perfectly.

The results of the final measurement show that the carbon-containing stains on the ink residue on the "Seal of the King of Dian" were indeed produced in the era of Emperor Liu Che of the Han Dynasty, who made Liu Che the emperor for 54 years, and such a long time has covered the error years of AMS.

However, when the "Guangling Wang Seal" was identified, the data displayed was rather strange. According to the Book of the Later Han Dynasty and the Ming Emperor, the "Guangling King Seal" should have been cast in the first year of Emperor Yongping of the Ming Dynasty, that is, 58 years.

"How can it be shown that the age of the remnants of the ink on this is at least 100 years later? According to the error, it may be almost the late Eastern Han Dynasty and the period of Chong Zhen Huanling. ”

This small accident made many Chinese experts a little embarrassed.

In the end, Director Ning of the Department of Archaeology of the Central University of Science and Technology, who came with Gu Wan, put forward his own views:

This is not surprising, because the year of the seal does not have to be the same as the year in which the seal was cast. If it is a seal that is in use all year round, the surface residue stain is later than the seal itself, which is very common in archaeology.

The seal of the king of Dian and the seal of the king of the Han Dynasty were both awarded to the kings of the outer vassals in the tributary system, and they did not necessarily use it when they returned to China after they got the seal letter rewarded by the Han emperor, so it is normal for the year of the seal to be similar to the year of the seal casting.

However, the king of Guangling was in the system of vassal kings of the Eastern Han Dynasty, and Liu Jing, the first king of Guangling, was the ninth son of Emperor Guangwu Liu Xiu and the younger brother of Emperor Liu Zhuang of the Han Ming Dynasty. According to the Book of the Later Han Dynasty, although Liu Jing himself was punished by Emperor Ming for many rebellions, he only cut his heir to the title of 'Marquis of Guangling', but his descendants Liu Yuanshou, Liu Shang, and Liu Tiao still 'obeyed Wang Xishou'.

It can be seen that the lineage of King Guangling was still active until the late Eastern Han Dynasty, and it is entirely possible that they will continue to use this seal. Therefore, it is normal for the C14 isotope abundance identification conclusion to show the age of the late Eastern Han Dynasty. ”

Gu Yu also breathed a sigh of relief, he was still afraid that his machine would drop the chain as soon as it was used for the third time.

Fortunately, Director Ning Bo Gu is familiar with the present, and the "Book of the Later Han Dynasty" is like a stream, quoting scriptures, and directly helping Gu Play to round the points that he can't explain.

It seems that there are still two brushes to be the head of the archaeology department of the Central University of Science and Technology.

After discussing the dating of the three things, the organizers of Fuso decided to hold a public academic conference at the Hakata Museum five days later, taking advantage of the opening of the Asia-Pacific Expo, to show the latest research results to scholars in the archaeological/historical circles of various countries and accept the cross-examination of international peers.

"Gu Sang, thanks to you this time, please allow me to express my gratitude to you on behalf of the Fuso archaeological community. When Professor Yamashita Takehisa of Kyoto University left the show, he sincerely thanked Gu Yu and bowed deeply.

Gu Yu also shook hands and returned the salute, but he couldn't help but feel that the other party was a little pretentious: Lao Tzu proved that you Fusang people really came to pay tribute and ask for rewards when they were really in the Han Dynasty, why do you still think that in the eyes of Fusang people, it is a matter of great face and gold on your face?

Sure enough, it is a small country in Dongyi, and it only worships the strong, hehe.

"In addition, we in the Fusang archaeological community also hope to join forces with several schools to raise funds to purchase an AMS mass spectrometer, I wonder if Gu Sang can help us contact on our behalf?"

Ma Yi translated this as usual, and Gu Yu was happy when he heard it.

This Yamashita Takehisa probably doesn't know that AMS's production contractors and overseas patent rights are all in Gu Yu's hands.

It is no wonder that in the eyes of those foreign scholars, those who engage in academic research are engaged in academic research, especially such unpopular academic instruments, and ordinary scientists will not personally produce and operate.

In addition, Gu Play is too young, which is too confusing, who would have thought that he would provide one-stop service for the whole industry chain.

Gu Yu pondered his tone: "Listen to him, my country's Ministry of Science and Technology has ordered a total of two sets, and the cost of each set can be as high as 5 million US dollars......"

Ma Yiyi translated it word for word.

Yamashita Takehisa hesitated for a moment, said that they would do it first, and then went out to make a few phone calls, and when he came back, he actually told Gu Yu that there was no problem in principle.

Fusang is relatively rich, and it is also the handful that is most willing to spend money on archaeology. Let them spend tens of millions of dollars on research and development, which is reluctant, but others have developed it, and it is still okay to spend $5 million to buy one.

The previous estimate of "as long as he doesn't go out in person and let others develop it, at least 50 million US dollars can be done" is to add a qualification, that is, "research and development in the eastern country".

The treatment and cost of scientific researchers in various countries are different, and scientists in Fuso and Oceania countries are more expensive, so it is normal for Fuso people to spend 80 million to get the scientific research that can be won by the Oriental countries for 50 million. In this way, it is more cost-effective to buy an imported product.

……

"It's only been a few days since I came, and I made $3 million, net profit, husband, you are really amazing. When I left the institute/museum, Ma Yiyi, who had witnessed all this, was so excited that her whole body trembled slightly.

Gu Wan tightened his hand around his waist domineeringly, and said in a high-spirited and flat manner: "In a few days, after the international academic symposium opens, it is estimated that a few more sets can be sold, and the 3 million in front of me will not be much against the sky at that time."

However, you should be careful to keep your prices confidential. Potential buyers from various countries must not be allowed to know what the price each other is getting. Perhaps, I will give some countries that are a little picky and hesitant, a little discount, 4 million units, maybe they will be sold, anyway, we still have some money.

This kind of business is also a one-shot deal, even if it is as strong as Oceania, at most two or three sets can be sold, and no matter how much it is, it will not be used. In the archaeological community of other second-world powers, if they are willing to buy a set, they will save face, and they will not buy a set that picks the door.

Therefore, by the end of this year at the latest, after the list is out, this technology will have little economic value, and the global market will soon be saturated. ”

Because the day is busy, everyone hasn't had lunch yet.

But I helped solve a big problem today, so the Fuso people feasted on a very good meal, and Gu Yu didn't have to eat ramen anymore.

The dinner was mainly sashimi, and there was also horse meat sashimi, which is a local feature of Kyushu. However, the level of the escort is not high, and there are no officials from the Ministry of Education, Culture, Sports, Science and Technology, so it is estimated that everyone is still busy preparing for the press conference in a few days.

Gu Yu ate hastily, and then went back to the hotel to rest.

Today's experimental results, of course, can also form several very high-quality papers.

The archaeological analysis of the liberal arts was naturally written by Director Ning and Professor Yamashita.

The first practical application of AMS mass spectrometer should be written by Gu Wan. It is estimated that this will be a masterpiece that can be on "Nature".

Gu Play writes quickly, the experimental data is sufficient, and there are so many peers to testify, so in just a few days, Gu Play submitted the paper.

……

After several days of hasty preparations, the day of the symposium is finally approaching.

Since the Asia-Pacific Expo has officially opened, almost all the hotels in Hakata City are full, and there are many visiting foreign scholars and foreign liaison officials from various countries.

It seems that the higher the status, the later the appearance of the big man, the scholars of Oceania chose to arrive on the last day before the seminar.

The people of Fuso are still very fond of this, and they are very respectful to the scholars of the Oceanic Kingdom.

"Professor Galfort, the seminar is scheduled for tomorrow at noon, in the large conference hall of our hotel, and the keynote speaker is Professor Takehisa Yamashita of Kyoto University, and there are three other speakers. ”

Professor Galfort is a professor in the Department of Archaeology at Stratholme University, although not the head of the department, at least he is a relatively senior expert in the study of East Asian history.

He has come to Fuso several times to participate in academic activities, so he is accustomed to the hospitality of Fuso people.

"Regarding the latest technical application results of isotope abundance identification, the source of the technology, is actually the Oriental country? What kind of awesome technology can this kind of country have? Impossible, C14 half-life identification technology, has not always been respected by our Oceanic countries?"

I don't blame this Galford professor for the frog at the bottom of the well, the main thing is that he is from the Department of Archaeology, not the Department of Physics.

Therefore, for C14 identification, he has always been only the identity of a user, and he doesn't care about the specific principle.

Over the years, the suppliers he met who invited him to dinner and gave gifts and sold experimental equipment to Stratholme University have of course blown Oceania's own science and technology into the sky, and it seems that there can be no new technical routes in the whole world, and there is no other way to be more awesome, so he has become arrogant.

"I'd like to see what this seminar can say!" said Professor Galfort, satisfied, and prepared to inquire about the Fuso evidence tomorrow.
