The distance of microphones in sound intensity probe have great relations with effective sound frequency band measured during measuring sound intensity,. To adapt different measured frequencies, the position of every microphone in sound intensity probe should be adjusted. On the basis of discussing the theory of measuring sound intensity with four microphones from three dimensions, using the theory about keeping place of brace framework and parallelogram, we designed a new 3D sound intensity probe including four microphones. Because space among different microphones in sound intensity probe can be adjusted, it can choose appropriate measurement bandwidth according to the range of sound frequencies measured actually. 3D sound intensity probe with four microphones, whose measurement frequency can de adjusted, retained original advantages of 3D sound intensity probe, and overcome the shortcomings of measuring fixed bandwidth.

This paper presents numerical simulation of a single drop impact onto a dry surface using combined Level Set-VOF method and a precise wetting model. This wetting model was base on the dynamic contact angle when drop spreading on the surface, which is a function of the instantaneous contact line velocity. The singularity at the moving contact line was analyzed and was removed by the wetting model. It is emphasized that the contact line velocity can not be approximated by the velocity of any material point, even when the point is very close to the contact line. This paper precisely captured the contact point and the contact line velocity. The wetting model with combined Level Set-VOF method was used to simulate the spreading of drops impacting a dry surface in low Weber number. The dimensionless spreading radius, the dimensionless height of drop and the drop shapes were compared with the experimental data. The numerical results agree well with the experimental data.

Exploration Seismology is a basic and important specialized subject of Geophysics in college. It's too hard to remember and understand so many concepts, processes and principles for students. And for teacher, the difficulties are how to explain these profound theories vividly in simple language. Based on this actual requirement, we developed the teaching simulation and demonstration software called OpenSE with Qt. As a GUI tool, it owns a powerful graphics library and cross-platform features that make “write once, compile anywhere” come true, so Qt becomes our preferred language to develop this set of software. Through our efforts, we complete the software, which greatly facilitate the teaching and student learning.

A double-pass noncollinear optical parametric chirped pulse amplifier has been demonstrated. The signal is double-pass amplified in a single nonlinear crystal by a nanosecond pump pulse. The first-pass optical parametric amplification is completely phase matched in the plane of the maximum effective nonlinearity, and the other pass works symmetrically near to the first-pass optical parametric amplification plane. This architecture efficiently increases the overall gain, overcomes the optical parametric fluorescence. This scheme has been used respectively in the optical parametric chirped pulse amplifiers which the signal is an Yb-doped passively mode-locked fiber laser or a Kerr lens mode-locked Ti:sapphire oscillator.
