Combining the quantum defect theory with the discrete oscillator strengths, the discrete oscillator strengths for 1s23d-1s2nf (n >amp;gt; 9) transitions and the oscillator strengths densities corresponding to the bound-free transitions are obtained.
      
It is revealed that the values of the oscillator strengths and the probabilities of spontaneous radiative transitions in Er3+ ions in the chalcogenide matrix are larger than those in phosphate, germanate, and tellurite matrices.
      
The operation of the oscillator is based on the creation of overvoltages across the spark gaps that increase from the first gap to the last.
      
The oscillator head is a waveguide section with a channel cross section of 7.2 × 3.4 mm2.
      
Both analytic and numerical techniques have been used in studying the oscillator dynamics at given beam parameters (configuration, electron energy, and current pulse), with different plasma configurations, and at various lengths of the system.

The main and ancillary factors which influence the oscillating cavity forming self-excited oscillation through the experiment is studied in this paper. The oscillators were compared and optimum seeked under the condition of experiment, based on which, the experimental research with leading-in turbulence were done. The purpose of the experiment is to supply a new thought for the design of drilling bit cavity, especially, it supplies the experimental evidence for the hydraulic system design of the small size cone bit. At the same time, the effort is made to find a new method of the fluid self-excited oscillating pressure boost.We adopted the replaceable oscillating cavity designed by authors in the experiment was adopted, it has three kinds of cavity diameters (50mm, 60mm, 70mm), and its cavity length can be steeples regulated. The experiment was done under the conditions of submergence by clean water and with no backpressure. In the case of submergence and freeness jet flow, the turbulence can be led-in by drilling a hole at the side wall of the oscillator, and the impact pressure of the jet flow can be measured at the outlet of the oscillator, then the experimental results can be analyzed through the waveform analysis and spectrum analysis.The experiment shows that the oscillator behaviors can be changed by leading-in turbulence, even possibly improved under some conditions. High power oscillator and producing self-excited pressure boost can form powerful impulse jet flow.

After the analysis of lack of injection in Lianjialou oilfield, an injection increasing technique by acidizing magnetization oscillation was put forward and its mechanism has been researched. It shows that the water injection after acidized then magnetized oscillation is a activating blocking relieved process.This process is helpful for injection and reduces the secondary blocking, so keeping the acidizing effect and prolonging the valid period of injection increase. Field practical applications show that valid period of acidizing magnetization oscillation for the injection is prolonged 1 37~ 3.75 times that of acidizing only. The effect is obvious.

Introduces working principle and structure of a indication and alarm device for over water content rate in piped crude oil. The electric amount in a capacitance in sensitive probe composed of emitting antenna and the corresponding oil transport pipe case will vary with water content rate in crude oil and the probe is also used as a modulate capacitance of a resonance circuit. The resonance circuit is coupled by inductance and obtains oscillating voltage from a stable crystal oscillator. When the capacitance of the sensitive probe is changed, the impedance of the oscillator circuit will be changed consequently, e. g. changes in oscillating voltage will occur. The change will be transferred into D. C. voltage changeable output through detecting circuit and displayed.
