Life figures

Graduated from compressor and refrigeration technology of Xi'an Jiaotong University in July 1982;

From August 1982 to August 1986, he served as technician and assistant engineer of power plant of Anyang Iron and Steel Company (deputy director of machine repair workshop since 1983);

In June 1989, he obtained the master's degree of chemical machinery and equipment from Xi'an Jiaotong University and stayed in the university to teach;

In 1995, he obtained the doctor's degree of refrigeration and cryogenic engineering from Xi'an Jiaotong University and worked in the National Engineering Research Center of fluid machinery and compressor;

In 1995, he received a doctor's degree in refrigeration and cryogenic engineering from Xi'an Jiaotong University. In 1998, he was promoted to a professor, and in 1999, he was employed as a doctoral supervisor. From September 1999 to November 2000, visiting professor of City University, UK. At present, he is deputy director of National Engineering Research Center of fluid machinery and compressor, executive director of Fluid Engineering Society of China Society of mechanical engineering, technical member of national refrigeration and air conditioning equipment standard committee, editorial board member of fluid machinery, member of Degree Committee and doctoral Steering Committee of School of energy technology of Xi'an Jiaotong University, professor and doctoral supervisor of refrigeration and low temperature engineering Teacher, won the title of excellent returned students in Shaanxi Province, and enjoy the State Council government subsidies.

At the end of 2007, six professors, including Chen Yongjiang of Xi'an Jiaotong University, reported in real name that Li Liansheng, a teacher of Xi'an Jiaotong University and deputy director of the National Engineering Center, and Shu Pengcheng, former vice president and director of the National Engineering Center, exaggerated their research achievements and described the problems solved by others as their own inventions when applying for the "first prize of science and technology progress of the Ministry of education" and "second prize of national science and technology progress". In May 2009, Xi'an Jiaotong University decided that Li Liansheng would "no longer serve" as the deputy director of the National Engineering Center of Xi'an Jiaotong University.

On March 21, 2010, the joint conference of the party and government of Xi'an Jiaotong University made a decision: in view of Li Liansheng's serious academic misconduct, he will cancel his professorship and his teacher employment contract. The day before yesterday, CCTV's focus interview reported the fact that the above six professors were hard to report with the title of "academic achievements" without results, and the university authorities repeatedly prevented them.

On the morning of March 21, 2010, Xi'an Jiaotong University held a joint meeting of the professional and technical post appointment Committee and the party and government of Xi'an Jiaotong University, which clearly identified that Li Liansheng had "serious academic misconduct" and made a decision to "cancel his professorship and terminate his teacher employment contract." In the past three years, Professor Liu first reported his former student for fraud. Later, the student took the teacher to court and went through many trials. It was not until March 21, 2010 that a absurd play in the context of academic impetuous ecology was finally decided by the school.

On February 10, 2011, the Ministry of science and technology said in a circular that, after investigation and verification, there were serious problems such as serious plagiarism of representative works and false economic benefit data in the recommended materials of "Research on Key Technologies of scroll compressor design and manufacturing and development of series products" which won the second prize of the national science and Technology Progress Award in 2005. According to Article 21 of the regulations on national science and technology awards and Article 92 of the detailed rules for the implementation of the regulations on national science and technology awards, with the approval of the national science and technology awards committee and the approval of the State Council, it is decided to cancel the second prize of the 2005 National science and Technology Progress Award for the project of "Research on Key Technologies of scroll compressor design and manufacture and development of series products" Take back the reward certificate and the bonus.

In May 2010, he was transferred from Xi'an Jiaotong University to Hefei General Machinery Research Institute as deputy chief engineer, playing an active role in the construction of State Key Laboratory of compressor technology, and carrying out effective work in compressor related technology research and development, international exchange, and personnel training.

Transferred to Qingdao University of science and technology in June 2017.

Fraud scandal

1. Ministry of science and technology annuls a second prize of national science and Technology Progress Award

2. "No" to academic fraud

Beijing, Feb. 10, 2011: the Ministry of science and technology and the State Science and Technology Award Office recently issued a circular, officially canceling the decision of former professor Li Liansheng of Xi'an Jiaotong University to win the second prize of the national science and Technology Progress Award in 2005, and taking back the award certificate and the bonus.

The reporter was confirmed by the national science and Technology Award Office on the 10th that this is the "first case" in China that the national science and technology progress award was cancelled due to academic fraud. This measure defended the seriousness of the national science and technology award system.

According to the circular, there are serious plagiarism of representative works and false economic benefit data in the recommended materials of the project "Research on Key Technologies of scroll compressor design and manufacturing and development of series products" which won the second prize of the national science and Technology Progress Award in 2005. According to Article 21 of the regulations on national science and technology awards and Article 92 of the detailed rules for the implementation of the regulations on national science and technology awards, with the approval of the national science and technology awards committee and the approval of the State Council, it is decided to cancel the second prize of the 2005 National science and Technology Progress Award for the project of "Research on Key Technologies of scroll compressor design and manufacture and development of series products" .

In early 2008, Yang shaokan, a retired professor of Xi'an Jiaotong University, and other six old professors reported serious academic misconduct, such as fraud, embezzlement of other people's academic achievements, patchwork and packaging, in the science and technology progress first prize project of the Ministry of education declared by Li Liansheng and other professors in 2007. Li Liansheng, former professor and doctoral supervisor of Xi'an Jiaotong University, is one of the main leaders of the science and Technology Progress Award project. After more than two years of court confrontation, in front of many false facts, Li Liansheng has been terminated the teacher employment contract by Xi'an Jiaotong University.

In March 2010, the professional and technical appointment Committee of Xi'an Jiaotong University and the joint meeting of the party and government of Xi'an Jiaotong University decided: in view of Li Liansheng's serious academic misconduct, he should cancel his professorship and his teacher employment contract. With the deepening of the investigation, the project that Li Liansheng won the second prize of national science and Technology Progress Award in 2005 was found to have many problems in the proof materials of economic benefits.
