Oh go, Gu Yu's invention and creation works have actually been shortlisted for the provincial selection!

After hearing this, the students in the first (5th) class in the class were stunned.

Even Teacher Liu Meixiao was overjoyed, turned to Gu Yu who was sitting in the last row and said, "Congratulations, classmate Gu Yu!" ”

Subsequently, Gu Yu was called out of the classroom by Teacher Zhu Qifeng.

In the corridor outside, Teacher Zhu Qifeng excitedly instructed Gu Yu: Get ready, tomorrow Friday afternoon, with two other students, follow Teacher Zhu Qifeng to take the train to Qianjiang City, the provincial capital, to participate in the exhibition and award ceremony of the 9th National Youth Invention and Creation Competition Donghai Province Division held in Qianjiang City on November 7 and 8, Saturday and Sunday.

This time, their works from Minghai No. 1 Middle School, including Gu Yu, as well as Ouyang Qingsha and Ge Junjie, were selected for the award ceremony of the Donghai Provincial Division.

Being shortlisted for the provincial selection means that there is an encouragement award at worst.

The final provincial first, second and third prizes will not be announced until the award ceremony on Sunday morning, November 8.

Originally, this Saturday, Tang Yiqiu asked his old classmate, Huang Kaifeng of Dongfang Electric Company, to talk to them about water dispenser cooperation.

After class in the evening, Gu Yu had to call Tang Yiqiu to cancel the meeting with Huang Kaifeng this weekend.

On the phone, Tang Yiqiu was also pleasantly surprised when she heard that Gu Yu's work was shortlisted for the provincial selection......

In the afternoon of the next day, after two classes in the afternoon, Gu Yu, Ouyang Qingsha and Ge Junjie followed Mr. Zhu Qifeng to the South Railway Station and boarded the train to Qianjiang City, the provincial capital.

On the morning of Saturday, November 7, the next day, the exhibition of selected works of the 9th National Youth Invention and Creation Competition in Donghai Province was held in the Provincial Cultural Hall (Exhibition Hall) located on Huancheng North Road, Qianjiang City.

More than 200 shortlisted works from 11 prefecture-level cities in Donghai Province were exhibited......

The entries for this National Youth Invention and Creation Competition are divided into eight fields:

(1) Mathematics: basic research and related applications in the fields of mathematics such as algebra, geometry, probability, and statistics.

(2) Physics and Astronomy: research and application in physics, electromagnetism, optics, heat and other physical disciplines and astronomy.

(3) Chemistry: research and application in inorganic chemistry, organic chemistry, physical chemistry, analytical chemistry and other related fields.

(4) Life sciences: experimental research or theoretical analysis in zoology, botany and other life science related fields.

(5) Computer Science and Information Technology: Theoretical research and technical exploration related to computer science and technology.

(6) Engineering: related research and application in the field of engineering technology such as machinery and circuits.

(7) Environmental science: research and application in environmental disciplines such as soil and water protection, climate change, and ecological protection.

(8) Behavioral and social sciences: investigations and studies on specific social phenomena, events, or problems......

When Gu Yu's water dispenser works were declared, they were classified as environmental science works; Ouyang Qingsha and Ge Junjie's "Wave Generator" and "Moon Phase Demonstrator" are classified as works of physics and astronomy.

Their entries and application materials were all sent to the provincial capital last week and handed over to the provincial review committee for selection.

At nine o'clock in the morning on Saturday, the "Ninth National Youth Invention and Creation Competition Donghai Provincial Division" and "Donghai Youth Invention and Creation Works Exhibition" were held in the Provincial Cultural Hall (Exhibition Hall).

Leaders and experts from the Provincial Department of Education, the Department of Science and Technology, the Provincial Association for Science and Technology, the Provincial Youth League Committee, the Department of Environmental Protection and the Customs Working Committee, as well as representatives of teachers and students from the province's education system, participated in the event.

After the grand and simple opening ceremony, the leaders and experts stepped into the exhibition hall and began to tour the museum.

Among the eight fields, the entries in physics and astronomy are the most eye-catching.

Soon, however, the leaders and experts who toured the museum were attracted by an entry in the field of environmental science.

This entry is Gu Yu's "ultrafiltration hydrophilic membrane anti-secondary pollution water dispenser".

This work has the largest number of onlookers in front of it, and it is also the most ornamental.

Next to the water dispenser are piles of beer, milk, ink and other items.

I don't know the inside story, I think it's a giveaway for sales promotion and attracting popularity.

In fact, for the demonstration effect of today's scene, Mr. Zhu Qifeng helped Gu Yu prepare them last night.

At the demonstration site, Gu Yu also prepared a lot of disposable paper cups.

At the request of visitors, he added various substances such as beer, milk and ink to the tap water in the funnel at the top of the water dispenser......

Subsequently, use disposable paper cups to catch cups of clear and transparent pure water.

After a few drinks as a guinea pig himself, he invited the surrounding audience to try the taste.

There were also bold viewers on the side who took a few bites and gave a thumbs up and praised: The taste is not bad, no impurities, no peculiar smell!

In the morning, he was also attracted by Gu Yu's "ultrafiltration hydrophilic membrane anti-secondary pollution water dispenser", and brought a bunch of people to Gu Yu's water dispenser.

He first carefully read the brief descriptions of the entries on the display board.

Subsequently, under the guidance of the leaders of the organizing committee on the side, Gu Yu and the instructor Zhu Qifeng reported to the leaders the design ideas and general principles of his work......

On this occasion, there are so many leaders and experts on the scene, as well as reporters from the news media.

Under the spotlight, in the face of various cameras and shots of long guns and short guns, even Mr. Zhu Qifeng began to get nervous, and fine sweat broke out on his head.

But Gu Yu looked calm, not panicked at all, and talked eloquently to the leaders and experts......

"Leaders, as a novel household appliance product, water dispenser is rising rapidly in China, and its production and sales are growing at a rapid rate every year. At present, the vast majority of water dispensers use bottled water, because the outside air will continue to enter the bucket when the faucet is discharged, causing bacterial pollution, thereby damaging the health of drinkers, seriously restricting the further development of the water dispenser market......

The technical problem to be solved by this kind of water dispenser invented by me is to design a kind of ultrafiltration hydrophilic membrane water dispenser with reasonable design, compact structure, and can effectively overcome the problem of secondary pollution of water dispenser water quality in view of the above-mentioned prior art status quo......"

Listening to Gu Yu's introduction, the deputy provincial leader nodded constantly and asked a lot of key technical questions, and Gu Yu answered them one by one, and he was very satisfied.

Before leaving, he actually drank a small glass of pure water sample handed to him by Gu Yu himself, and praised: "Well, it tastes good!" Gu Yu, I hope that in the near future, you will be able to buy this water dispenser you invented on the market! ”
