With the rapid development of the integrated circuit industry, wafers, as the carrier for chip manufacturing, have made their production efficiency and quality the focal point of industry attention.

The idea that gravity shapes the universe into nicely bounded superclusters is being overturned by a finding so gargantuan ...

An underwater gravity survey just above seafloor can directly give localized mass distribution below the seafloor. Therefore, we have developed an underwater gravity measurement system onboard an ...
