查询词典 nuclide

The concentration of Cosmogenic nuclides is not only constrained by production rates and exposure time, and also closely related to surface erosion. Furthermore, the concentration is affected by geomagnetic intensity, shielding, chemical weathering, and sample geometry as well. These factors affecting Cosmogenic nuclide concentration should be calibrated when surface exposure age is calculated.

Abstracts: To sample high speed random signals without drop, a design of O-shaped high speed random signals acquisition card based on the CPLD and its realization are presented. It consists of same three sets of acquisitive circuits, which construct O-shaped structure to sample the signals without drop .And it adopts threshold judging method to determine the valid data in the process of the acquisition, abandons vast of the redundant useless data at the same time, it only sends the useful data to the host computer by the way of DMA, so it is easy to processing the data. The design is concise and reliable. The sketch map of the logic circuit and the explanation of the main parts are presented. This design has been applied in the engineering project of sampling α nuclide.
