With coupler embedded and acceleration sensitivity compensation design, the structure symmetry is insured, which can induce the acceleration sensitivity effectively. The acceleration sensitivity compensation design also improves the production efficiency of FOH for towed linear array application.2. A good theoretical simulation platform, utilizing the method of elastic mechanics and the finite element method, is established, which can provide an effect predictive design for FOH. The experimental results are in good agreement with the theoretical analysises.3. Some key technology problems in the making of FOH for towed linear array application are conquered. The new developed FOH, with an acoustic sensitivity of -143.0dB, has acceleration sensitivity less than -30dB, which exceeded to results from other international reports.

Thehigh-density array has threshold energy of about 2TeV. With the YangbajingAS γ array, upper limits of γ-ray fluxes from many high energy galacticcelestial objects including Crab Nebula and active galactic nuclei weremeasured at the energy around 10TeV, and the possible evidence of existing10TeV cosmic gamma ray burst was looked for. The Sun's shadow of cosmicrays has been observed and shift of the Sun's shadow resulted from the solarinterplanetary large scale magnetic field was found. And the ultra high energyspectrum of primary cosmic ray around the 'knee' was reached.
