Combining theory with practice doubles the results

The combination of theory and practice can achieve twice the result with half the effort, something I have deeply experienced through my work. Case 1: When I first joined a company, I had spent many years researching a certain product; however, due to my limited educational level, I only had practical experience and not much theoretical knowledge. When technical problems arise, the proposed solutions lack theoretical backing, and their feasibility can only be verified through continuous testing, which requires significant investment of time and resources. If such products without theoretical support are released into the market irresponsibly, our customers end up serving as test subjects. After discussing the issue with the doctors in the office, the direction to take was quickly identified; by following this direction and conducting corresponding practical tests and verifications, many detours were avoided. Without the theoretical support of a doctorate, I will likely continue to trial and error my way forward for a long time ； A doctor lacks the practical experience I have, and is also unaware of the theoretical feasibility; thus, such theory exists only in doctoral theses... Case 2: Enameled coating thickness issue: GB25025 specifies the allowable range for enamel thickness, while DIN standards require even more precise specifications. Back then, I only knew that one had to follow the rules without understanding why; it couldn’t be too thin, as thin layers had limited corrosion resistance, nor could it be too thick, as thickness could cause the porcelain to crack. But if you tried to figure out why thickness led to cracking, there was no way to know... That’s what happens when there is a lack of theoretical knowledge. The main component of enamel glaze is SiO2, along with many other elements. During the firing process, the inner and outer layers cool at different rates, which results in stress within the glaze of these layers ； The thermal expansion rates of the ceramic glaze and the substrate are different, and stress is generated during heating and cooling processes. In addition to the stress resulting from welding structures and the structural stresses inherent in the equipment itself, these factors mean that the thickness of the enamel coating cannot be too great. Theoretically, it depends on various factors such as the compressive strength, tensile strength, elasticity, and adhesion strength of the ceramic glaze... I have worked for several companies; I enjoy discussing issues with front-line workers, colleagues from different departments, and those in various positions. Through these discussions, I gain different perspectives on how to address certain problems, which is very beneficial for me... I believe that sharing knowledge is highly useful for my rapid growth... I would like to thank some of the friends at Haichuan for their assistance: handshake
