Simulation shows that the inhomogeneity of electric field reduces the oscillations in photodetachment cross section and its corresponding modulation function.
This phenomenon is called the excessive thermotaxis effect of low current.Based on these characteristics, the uniformity of the junction temperature distribution is studied.
In the production process of PCB, there are many defects such as surface smudginess, solder mask unevenness, text excursion, pad damage, track damage etc.
This paper introduces the geological features and the unhomogeneous weathering phenomenon of coral reef limestone of Sudan Port Area,and the bearing capacity of this layer.
Depth of field: with prqactices diode system (IDS), high-capacity ensures that the depth of field in the production of reliable. Autocompensation printing plate surface unevenness.
