1. High Q-value piezoelectric crystal transducer produces strong ultrasonic power.

2. For this reason, the inversion of Q-value for weathered layer is necessary.

3. According to the result of genetic structure component (Q-value), numerous inbred lines in each group were overlapped in genetic component with the other groups.

4. The Q-value studies are not only studied by the natural seismic wave, but also in the laboratory, where the attenuation theory of seismic wave and observing method of measuring Q-value are studied.

5. The resonance frequency, Q-value and field profile function are solved numerically. On the basis of this, the large signal analysis of it is carried out.

6. Common methods for Q-value calculation are rise-time method, spectral ratio method, spectrum modeling method, wavelet modeling method and so forth.

7. Thispaper makes use of surface waves to find Q-Value in weathered layer.

8. The major methods of measuring Q-value by the natural earthquakes are the ones of using the data of free vibration of earth, body wave, surface wave and coda.

9. Some optimization designs were made with the on-chip inductor and the RF switches to get the maximum Q-value.

10. In this paper, an 0-1 programming model on just allocation of seats number and its solution have been given, the results have improved the traditional Q -value method and the new Q-value method.

11. Hence we derive the expression of fitting function and propose a new Q-value inversion method using non- linear parameter statistical modeling of seismic records.

12. Product Features: It adopts the advanced domestic and foreign technology and uses the high Q-value crystal transducers.

13. A novel double-sampling double-delay switched capacitor resonator with high performance is proposed. High notch Q-value and accurate notch frequency are analyzed at the transfer function level.

14. It completes the system control software and FPGA control logic design, and achieves the data-processing function of amplitude and phase-frequency testing, parameter storage, calculation of Q-value.sentencedict .com

15. If the study's dissolution average shows a decreasing trend with time that indicates difficulty remaining above the registered Q-value through expiration, this fact could indicate a compliance alert.

16. After iterative refinement of each processing step, the optimal word-length and Q-Value of each intermediate results and coefficients are evolved.

17. With the raising of people's observation and development of observation measures, the Q-value studies reflecting the media characteristics of the Earth are continuously deepened and developed.

18. Using the method of the form function of the envelope, the Q-value of crustal media in the Ningxia region is determined.
