1. Liu Zongming has made significant academic achievements in the fields of "Multiphase Flow Theory and Application (Powder Engineering), Thermal Energy Engineering, and Resource Comprehensive Utilization". His research results have been published in a series of internationally renowned academic journals. Firstly, he published an article titled "Extrusion Pneumatic Conveying in Dense Flow Regime" in the proceedings of the 3rd Beijing International Conference on Cement and Concrete in 1993. Subsequently, his research delved into the pressurized fluidized bed combined cycle (PFBC) technology and explored the cold model for fine ash discharge. This paper was included in the 1995 supplement of China Shipbuilding Industry. In 1996, he shared his research results on "Gas Physical Measurement Using an Extended Throat Venturimeter" at the Contemporary Fluid Measurement Technology Conference in Nanjing. In the same year, he presented a study on the influence of compressible gases in squeeze flow pneumatic conveying at the International Electrical Engineering Conference held in Japan, which was included in ISTP. In 1998, Liu Zongming published a study on the resistance characteristics of squeeze flow pneumatic conveying in the Journal of Southeast University, which was published in Vol.28. He continued to conduct in-depth research on the influence of active agents on the performance and hydration mechanism of sulfoaluminate cement. His paper was included in the 2180 issue of Cement and Concrete Research and was also included in SCI. In 2003, he presented an experimental study on fly ash removal at the International Energy and Environment Conference in Shanghai, China, titled "An Experimental Study on The Fly Ash Removal by Dense Phase Pneumatic Conveying", which was included in EI. In the same year, his other research on online control of dense phase pneumatic conveying was also included in EI at this conference. The publication of these papers fully demonstrates Liu Zongmings profound academic achievements and practical experience in the fields of pneumatic conveying technology and cement engineering.

1 At present, there are mainly two types of air flow sensors: hot wire air flow sensors and hot film air flow sensors, which are generally installed between the air filter and the throttle valve. Function: Measure the intake volume of the engine and input the signal into the ECU as the main control signal for fuel injection and ignition control. Fault mode: After the malfunction of the air flow sensor, the cars electronic control unit (ECU) cannot detect the true intake air volume, resulting in an imbalance of the mixture, leading to unstable engine idle, weak driving, black smoke, and sometimes shifting gears and stalling. 2. The intake pressure sensor, abbreviated as MAP, is installed on the intake manifold
