Effect of storage time on content of paeonol in prepared drug and material drug of Cortex Moutan;

The storage time of molasses has great effect on yeast production.

The models of Monte Carlo method of the storage time of the multiple-tunnel-junction single-electron memory device is established in this paper.

The influence of deposition rate of Si_3N_4 film on storage time of MOS capacitor exists because of its tensile stress,which can be reduced by annealing.

SAW memory correlator is an excellent non linear effect SAW device fabricated on GaAs substrate,in which piezoelectric characteristic is employed Some sensitive issues related to this device,like storage time and ion implantation ect,are also examined in detai

Changing the applied voltage and pulse duration applied to the AFM tip and sample during the fabrication of nano-oxidation dots, it is found that the dependence of the height and width of nano-oxidation are logarithmic correlated with the applied voltage while exponentially correlated with the pulse duration.

When the pulse duration was fixed at 40 μs,0.

The theory of field-induced oxidation and the impact of bias voltage and pulse time on the nanofabrication were studied by AFM.

This paper describes that the output precision of the GPS Clock s time pulse is within 10 -6s after adopting technology of synchronous timing.
