- This study purposes to explore electrophysiological mechanism of short P _ R interval syndrome with supraventricular tachycardia. Authors carried out electrophysiological studies in 7 patients with short P _ R interval syndrome and supraventricular tachycardia.
- The maximum velocity V in blasting vibration is a random variable, it has no definite function relation to Q and R in general meaning. So V only can be controlled in a confidence interval.
- Proposes mean and range control charts with variable sample size and sampling interval time to signal for x and R charts and combined x and R charts.
- Several methods including vitrinite reflectance ( R_o ), interval transit time and apatite fission track, are used to reconstruct the sedimentary thickness of Middle-Lower Triassic, and to plot the isopach map of the proto - type basin.
- Then simulation analyzes the relation be-tween theR ( S / N ) ratio of the DRM system and channel delay (τ) as well as the gain of multi-path ()ρ, proving that appropriate guard interval has great immunity to the ISI.
