谁帮我翻译一下这段文字,翻译成英语,急啊!

Organization was short-pulse laser, if the pulse duration is much smaller than the area the organization absorb heat conduction time, regional organizations absorb laser energy absorption of a local temperature rise and a further expansion of insulation ultrasonic radiation. The so-called "adiabatic expansion" means that the light generated by the acoustic signal in the absorption within the region transit time under the same conditions are far greater than the time required for thermal diffusion, negligible effect of the proliferation of light signal the impact of this Conditions, acoustic imaging to short-pulse laser for excitation, ultrasonic signal for the information to the carrier, with high-resolution and high-contrast imaging features.
Subject to the requirements of numerical simulation of the means of ultrasonic signals generated image reconstruction algorithms and study the current Photoacoustic imaging used by several major image reconstruction method has been discussed and is the main derivation . Verify the effectiveness of image reconstruction algorithms and image in the process of rebuilding the main factors, including the main contents of the methods used numerical simulation of ultrasound signal frequency of study, the frequency characteristics of the probe, the filter frequency signals of recovery . On this basis, the actual experimental data processing and imaging, to further explore the data signal processing and image quality of the relationship between.
