ANALYSIS OF INHERENT CHARACTERISTICS, LOAD SHARING CHARACTERISTICS, AND TRANSPORTATION MECHANICAL RESPONSE OF A TRANSMISSION SYSTEM IN A LUNAR SAMPLER AND ITS EXPERIMENTAL VERIFICATION

A rotary driving component is the power output unit of a lunar sampler.A planetary gear system is used as the transmission system.The lunar sampler is subjected to an extremely rigorous mechanical environment during Kitchen Tools transportation.In this paper, the time-varying meshing stiffness curves of planetary gears are calculated by the Shi Chu

Leaf traits can be used to elucidate vegetation functional responses to global climate change.Pigments, water and leaf mass per area are the most used traits.However, detailed anatomical traits such as leaf thickness, the thickness of palisade and Tank spongy parenchyma are often neglected, although they affect leaf physiological function and optic

A high resolution surface topography Digital Elevation Kombucha Herbal Tea Model (DEM) is required to underpin studies of the complex glacier system on the Antarctic Peninsula.A complete DEM with better than 200 m pixel size and high positional and vertical accuracy would enable mapping of all significant glacial basins and provide a dataset for gl
