Four aspects of research achievements include:(1)several imaging correction methods and strained estimation methods for biological tissues elasticity imaging were investigated as well as elasticity reconstruction and phantom, in vitro and in vivo elasticity imaging experiments;(2)in the fields of biological microsystem and perfusion evaluation for microvascular system, three kinds of microbubbles whose shell are albumin, sugar ester and surfactant respectively were designed and produced, then the methods to estimate the thickness of their shells were presented, moreover, the interacting mechanism of ultrasound contrast agents and tissues, as well as protein drug delivery under the condition of ultrasound sonification were studied in the molecular level;(3) At the aspect of high intensity focused ultrasound therapy system, we designed and constructed the 256-element HIFU transducers using 1-3 composite materials. And furthermore we developed the integrated HIFU system with 256-element HIFU transducers. And we made preliminary and important progresses in the research of HIFU bioeffect, lesion estimation, techniques of monitoring and imaging and characterizing of structure of HIFU transducer;(4)The real-time method of voice source regeneration based on compensative regulation of physiological parameters was investigated in the field of medical rehabilitation. We addressed the physiology and biophysics of vocalization, modeled voice source regeneration based on compensative regulation mechanism, and put forward an integrated evaluation about the speech rehabilitation and the regenerated voice source; Sixty-one archived journal papers were published, as well as ten in international journals, and eighteen publications were embodied by SCI.

Based on studies about current development of Methods of separating meiofauna, a new method is advanced in this paper. A suit of device was designed to Separate meiofauna from benthic sediments sample automatically, accurately and efficiently, which based on the technology of Laser-induced Fluorescence Detection, and used other technologies, such as noctilucence, electronics, biophysics, computer, mechanism, and so on. The scheme of macrocosm, the design of light route, the hardware and software design of the photoelectricity detection system and machine control system, the method of signal processing are introduced, especially the hardware and software design and the method of signal processing.

论文分析了目前国内外所使用的小型底栖生物分离方法现状，并以此为基础，自主开发了一套基于激光诱导荧光技术，并且集荧光化学技术、电子物理技术、光电测量技术、计算机技术及机械技术为一体的小型底栖生物标本自动分离系统，实现了从沉积物样品中自动分离小型底栖生物标本，从而大幅度提高室内小型底栖生物分样的工作效率和精度的目的，并以此完成了大洋协会&十五&攻关项目：&小型底栖生物标本自动分离系统研制&。

Considering many biophysics processes such as the atmosphere,hydrology,plant leaf N content et al.a multiple layer,two-leaf canopy model for predicting of mass transportation and energy exchange between plant canopies and the atmosphere has developed after dividing the canopy height into three layers,and the sunlit and shaded leaf area index was computed respectively at different layers through introducing a foliage clumping index,it is important to distinguish the spatial light distribution and so leaf photsynthesis.

多层—双叶模型对冠层上方碳通量的模拟：综合考虑农田水、热因子及叶片氮含量的非线性垂直分布对碳、水循环的影响，将农田按植株高度分为上、中、下三层，并通过叶片集聚指数计算阴、阳叶面积以区分叶片的空间分布受光状态，建立了均匀农田与大气间物质输送和能量交换的多层—双叶模型，对农田冠层上方基于光合—呼吸的碳循环过程进行了模拟应用研究。
