Comparison of linewidth measurement using different probe based on the least square fitting model;

Study on Nano-scale Linewidth Measurement Technology;

This paper introduces the line width and text orientation control of inserting the AutoCAD graphics in Word in some ways,compares several illustrations and analyzes the conception of layer and finds an optimum method of editing the line width and text.

: During the fabrications of MEMS with thick resist lithography technique, most elements need better line width and vertical sidewall, so rigorous control of exposure dose and development time is necessary to get better patterns.

In this paper, we got the regularity of cavity ring-down spectroscopy when the line width of laser pulse is far larger than the absorption line width of measured substance.

Research results show that lengthening external cavity will make FBG-ECL have narrow line-width.

33cm￣(-1))has been measured and analysed,obtaining widths and strengths ofeight absorption lines and the first showing that line coupling not only effects on the absorptioncoefficient but also on the measurement accuracy of line-width and line-strength.

We derivation and analysis the filtering characteristic of this two ring resonator filter,the line-width and finesse of single ring resonator filer,the mode splitting of Mach-Zehnder ring resonator filter and the effect of cavities loss are also discussed.

Effective compression of laser pulses using backward SBS of broad-band and multi-transverse mode Cr:LISAF laser pulses is realized.

Under the condition of given pump laser energy, using a lens with short focal length to focus the Cr∶LiSAF electrooptical Q- switched  laser pulses into CS 2 SBS-cell, the backward SBS scattering of broad-band and multi-transverse-mode Cr∶LiSAF laser pulses is realized, and the effective pulse width′s compression is observed.

Application of broadened line plus large geophone array seismic technology in exploration in mid Kuqa;

In data acquisition, we introduce the application of broadened line technology in the mountainous seismic survey, high precision measurement technique suitable for high-density (10000 channels) seismic data acquisition, and absorptive medium simulation based layout design.

The scattering noise caused by various flank and surface factors can be suppressed by using detection method of broadened line and lateral long distance geophone array in seismic data acquisition,which effectively improves the signal-to-noise ratio of original data.
