Based on the Laser Doppler technology, Information technology, Image Recognition and Process tenology, the laser image characteritics of ultra-fine and non-spherical particles are studied. The laser image recognition method based on neural network theory are obtained. The associated hardware and computer software for analysis of the shape characteristics are developed. The shape characteristics of typical particles such as fire smoke particle and carborundum are studied by using such method. The results of this project are useful to develop the new reliable, accurate and rapid experimental diagnoses technology.

本项目综合应用激光多普勒技术、信息技术和计算机图像识别处理技术，研究了非球形超细微粒的激光影像形成规律，建立了基于神经网络理论的粒子形状特性测量方法并发展了相应的硬件系统及其计算分析软件，并利用该系统研究了火灾烟雾颗粒、金刚砂等典型非球形超细微粒的形状特性，已初步形成了可靠、准确、快捷的新型实验诊断方法，为进一步发展实用的非接触诊断技术提供条件。

Higher efficiency of transgene on penggan and longan resulted significantly from carborundum wounding followed by coinfection with Agrobacterium-mediated transformation.

通过金刚沙创伤处理比未创伤处理的均获得了较多的Kan〓胚状体。从结果分析可见，金刚砂创伤对椪柑和龙眼转化效果的影响，均达到显著水平。

"It is the most abundant metallic element in Earth's crust, chiefly in bauxite, feldspars, mica s, clay minerals, and laterite. It also occurs in gemstones, such as topaz, garnet, and chrysoberyl; emery, corundum, ruby, and sapphire are crystalline aluminum oxide."

为地壳中丰度最高的金属元素，多存在于铝土矿、长石、云母、黏土等矿物和砖红壤中，也存在于宝石之内，如黄宝石、红宝石及金绿宝石；而刚玉金刚砂、深红宝石及蓝宝石则为晶透的氧化铝。
