"I hope that more units, communities and the general public will actively participate in and support the popularization of science." On September 17, 2022, the theme of "Celebration of the 20th National Congress, popular science to the future", The event and the 5th Popular Faculty of Faculture started in the South China Botanical Garden. Zhong Nanshan, the winner of the Republic of the Medal and the academician of the Chinese Academy of Engineering, brought a cloud message. It is reported that this National Popular Science Day event will continue until September 21. During the period, Guangzhou will organize 187 units and institutions such as the organization, enterprises, schools, and scientific research institutes throughout the city to carry out various forms of online and rich content online online. There are 218 science science activities.

In the video speech, Zhong Nanshan wished the Guangzhou National Science Popularization Day event a complete success, and said that the event provided a popular science feast for the general public to create a social atmosphere of science, love, science, and science in the city. Plantation encourages the fertile soil of innovation and science. On the same day, there were also colorful theme activities such as Popular Science Popularization, Popular Popularized Micro Class, Popular Science Documentary Startup, Popular Science Show Performance, Popular Popular Photo Exhibition. At the event site, the first batch of scientific communication ambassadors in the Guangzhou Science and Technology Communication Alliance and the first batch of experts in Guangzhou Science Science Research Think Tank were issued a letter of appointment, and in 2022, the outstanding units, outstanding popular science workers and outstanding science and technology volunteers of Guangzhou science popularization work were awarded.

The main venue has a total of "extraordinary ten years" science and technology achievement exhibition, ecological civilization, frontier in the bay area, "four deep" (deep sea, deep space, deep blue, deep) exploration, rural revitalization, civilized mark, digital melt, health care, health care, health care, health care, health care, health care, health care, health care, health care, health care, health care, health care, health care, health care, health care, health care, The 143 booths of 10 major exhibition areas such as food safety and science popularization in the future, concentrated reflecting my country's scientific and technological achievements, and the effectiveness of scientific and technological achievements in promoting development and improving people's livelihood.

The reporter saw at the popular science carnival that the teachers and students of the Guangzhou University Physical Laboratory specially brought some special devices, allowing citizens to operate a Nobel -level physical experiment by themselves, which can be called the ceiling in this event. Citizens can operate at the scene to obtain a densely root oil drip experiment at the 1923 Nobel Prize in Physics and the team's ultrasonic speed.

According to the person in charge, Teacher Ma, the "Mi Li Gen Oil Drop Experiment" is a physical experiment conducted by Andrew Mi Ligen in 1909. This experiment transformed micro -amount into a macro measurement. It uses relatively simple instruments to make comparisons to compare the comparison Accurate and stable measurement.

I saw the operator spray the oil from the spray port next to the oil at the foggy room. By adjusting the experimental instrument (lowering the brightness of the monitor, the contrast is maximized, the scoring hand snail of the microscope is fine -tuned), so that there are a lot of appear in the field of viewing the field. Clear oil droplets, track and measure it, and processes experimental data (such as oil drop speed), you can test the non -sustainability of the charge, and calculate the basic charge in the oil droplet.

In addition, citizens can also go to the Physical Laboratory of Guangzhou University at a certain time after signing up on the spot to experience more Nobel Prize -level experiments, and once a real "physicist".

The scientists of the Guangzhou Institute of Energy of the Chinese Academy of Sciences show the citizens a set of geothermal energy transformation mining and efficient utilization technology: ultra -long gravity thermal tube geothermal system. According to reports, thermal tube is also known as the "heat-superconductor", and its equivalent heat conduction rate can reach 1,000 to 10000 times the metal conductivity, which is one of the most efficient heat transfer devices known at present. Gravity heat pipe evaporation section is below the condensate section. The condensation section rely on gravity to return to the evaporation section. The boiling increase in the tube body through the process of boiling-condensation decreases through the work quality, and the long-distance and high transmission of the thermal energy from the evaporation section to the condensation section is achieved. The length of the ultra -long gravity of the geothermal energy mining may be thousands of meters and the length of the length of length may exceed 10,000. The design, preparation and operation control of the thermal pipe is very critical.

How can we create a hard -to -sick physique? How to achieve easy learning without forgetting? How can we also ensure normal vision while growing up? The Guangzhou Nutritionist Association brought a set of nutritional diet plans to answer the citizens at the scene. Yang Li, Executive Vice President and Secretary -General of the Association, told reporters that the association has recently launched a set of 6 to 17 -year -old students' nutritional meal recipes and dietary guidance manuals to provide guidance for the improvement of dietary nutrition improvement in children and children. Children's nutritional meal provides reference reference.

It is understood. During the event, Guangzhou will also organize 97 national key laboratories, provincial key laboratories, high -tech enterprises and other units that meet the open conditions in Guangzhou, and will be open to the public for free. The city's 11 districts in the city carried out the national science popularization day, setting off a wave of popular science activities, focusing on creating a good atmosphere of love and advocating innovation, and promoting the results of the results of scientific and technological innovation and the popularity of scientific popularization activities.
