In measurement system by means of pulse laser, such as plasma measuring, laser ranging, the amplitude of echoed laser wave is very weak and difficult to detect by traditional analog electronic technology. A digital high speed data acquisition and processing system was designed to meet the accuracy requirement. It adopted high speed AD chip and advantage FPGA chip as core unit. Experiment results have verified this system can reach to 1GHz sample rate and can catch weak echo wave effectively and the measuring accuracy is improved markedly.

Objective The purpose of this study was to evaluate the clinical value of 3D-CPA in differentiating epithelial ovarian tumors by studying their vascular *** 67 epithelial ovarian tumors（40 ovarian carcinomas, 27 benign epithelial ovarian tumors） were examined preoperatively with 3D-CPA. The vascular pattern and vascularity index of tumor were assessed respectively. VEGF protein and microvessels were stained immunohistochemically by using antiVEGF and anti-CD34 antibody respectively after operation. Both the microvessel density（MVD） and the intensity of VEGF staining were *** The MVD in ovarian carcinomas（38.8±5.9/400×magnified field） was significantly higher than that in benign epithelial ovarian tumors（15.5±5.0/400×magnified field）（P3 was considered as the cutoff of vascularity index, the sensitivity and specificity of vaseularity index in detecting ovarian carcinoma were 77.5% and 81.5%, respectively. The vascularity index was correlated with MVD in ovarian *** 3D-CPA may be used to evaluate the angiogenesis in ovarian carcinoma before operation and could provide valuable information for the differential diagnosis of epithelial ovarian tumors.

Based on a combined sensor with the size of 10 cm, a narrow beam with a constant receiving beam width of 20 degree has been formed in low frequency from several Hz to thousands of Hz by using simple adaptive algorithm. The results of theoretical simulation, laboratory experiment and lake experiment with one-dimension and two-dimension combined sensors have been given.

This paper presents a new ultrasonic NDT technique for measuring the thicknessof a nonmetal material(called the ciadding material)with low sound velocity which iscladded on the one side of a thin metal plate(called the base)with high sound velocity such as tubes,tins and other closed containers,testing and inspecting the unglued area betweenthem,detecting the inner defect of the compesite from the side of the base in case that themeasurement and inspection has to be carried out on the side of the *** principle ofthe technique is that a longitudinal or transverse wave induced by the pulse Lamb wave inthe base is transmited in certam direction into the compounded material,then reflected bythe upper and lower boundary of the compounded *** same mode pulse Lambwave is formed while the longitudinal or transverse wave in the compounded material returnthe base.
