Yesterday, honorary manager of Peking University and Bill Gates, co-chair of the Bill and Melinda Gates Foundation, visited Peking University and delivered a speech entitled "China's future: innovation, charity and global leadership."
After the event, Peking University gifted Bill Gates with a special gift: a giant table tennis racket with numerous signatures signed by Liu Guoliang's Chinese table tennis team.
Gates revealed in his speech that he is a super table tennis fan. In 2008, Gates came to Beijing University to watch a table tennis match at the Beijing Olympics.
In addition to the star's signature, the racquet also read the words "about one in the north." From the scene photos, Gates is very satisfied with the gift, his face has always filled with a smile.
Rectifier Diode(Standard Diode)
Rectifier Diode(Standard Diode) utilizes the unidirectional conductivity of the diode, which can convert the alternating current of alternating direction to a pulsating direct current of a single direction. Rectifier diode – diode designed for rectifying alternating current (mostly with low power frequency – 50 Hz at high power emitted during load). The main task of the rectifier diode is to convert AC voltage into DC voltage through application in rectifier bridges. The variant of rectifier diodewith the Schottky barrier is particularly valued in digital electronics.
