报道了一种利用长焦区聚焦超声换能器检测光声信号的扫描光声乳腺成像系统.通过增加聚焦换能器焦区的长度,该技术可以快速实现对大块组织(如乳腺)的光声成像.测试结果表明,该实验系统能够对大块模拟样品中吸收体的位置、尺寸以及光能量吸收情况实现较为准确的成像.另外,实验中,该系统还可便捷地与传统的超声技术相结合,从而实现多模式复合的乳腺癌诊断.初步结果显示了该技术路线在乳腺癌早期诊断应用上的前景.

作者： Yaoping Chen (Concord University College of Fujian Normal University, fuzhou 350007)

In this paper, we consider a discrete nonlinear predator-prey model with nonnegative coefficients bounded above and below by positive constants. We show that under some suitable assumptions the predator species is driven to extinction and the prey species x is globally attractive with any positive solution to a discrete Logistic equation.

The investigation of the esterolysis of p-nitrophenol acetate (PNPA) catalyzed by alginate-cobalt(Ⅱ) complex membrane was carried out under various conditions. The results showed that the pseudo-first-order plots of the hydrolyses of PNPA catalyzed by alginate-Co(Ⅱ) complex membrane were linear. The kinetic constants were obtained and showed that the hydrolysis reactions obeyed Michaelis-Menten equations, showing an enzyme-like catalytic function of the membrane.

Although the southeast Fujian Province has favorable bio-climatic conditions, traditional farming models are limited in effective exploitation of agriculture related resources and have deteriorated the agricultural environment. After analyzing the conditions at Maping town, we designed a three-dimensional model, special ecological agricultural system (SEAS), at Maping town. The SEAS has been practiced for three years and results show that the SEAS more efficiently utilizes local time and space resources and gains more econo- mic, ecological and social benefits. Thus, the SEAS has been considered as an optimal model for sustainable utilization of agricultural resources.
