The experiments showed us : firstly , mediums with different magnetic and dielectric properties had different influence on the microwave - absorbing properties of spinel ferrite ; secondly , magnetic texture treatment greatly affected the microwave - absorbing properties of the spinel ferrite - based mixed material which contained single - domain particles of hexagonal ferrite , changing the matching thickness , the density of area and the position of absorption peaks and increasing the absorption quantity and the 10db bandwidth ; thirdly , the coupling effect between different layers affected the microwave - absorbing properties of the double - layer spinel ferrite - based mixed material , decreasing its matching thickness and density of area and increasing the position of absorption peaks 实验发现： ( 1 )不同磁性与电性的介质对尖晶石型铁氧体吸波特性的影响不同； ( 2 )磁织构化处理对含有六角晶系铁氧体单畴颗粒的尖晶石型铁氧体基混合吸波材料的性能影响很大，可以改变匹配厚度、面密度与吸收峰峰位，提高吸收量与10db带宽； ( 3 )对于双层材料，层间耦合作用会影响其吸波性能，降低匹配厚度与面密度，提高吸收峰峰位。
Time series of discharge in neurons , that is , interspike interval ( is i ) series of action potential is considered to contain plenty of sensory information . however , there is little understanding of basic type and generating mechanism of this time coding because of the complexity of isi series 神经元放电的时间序列，即动作电位的峰峰间期( interspikeinterval , isi )序列被认为蕴含丰富的神经信息，但是由于isi序列的复杂多变，至今对这种时间编码的基本型式及其发生机制了解很少。
On the basis of depositional studying of single well , concluding lithofaces - paleography of every formation : yeli - liangjiashan formations deposit in restrained sea ; lower majiagou formation early in tidal flat and late in restrained platform ; upper majiagou formation early in tidal flat and late in open sea ; fengfeng formation early in tidal flat and late in open sea 指出冶里组?亮甲山组以局限海沉积为主，早马家沟早期潮坪发育，晚期为局部台地，晚马家沟早期仍有广泛的潮坪发育，晚期则以开阔海为主，峰峰期早期潮坪广布，晚期则以广泛发育开阔海为主。
After that , based on the problems existed in current feng feng mine bureau material supply system , taking the advanced idea of modern logistic management , this dissertation gives a solution to realize informationization of material supply management for feng feng mine bureau . the solution adopts object oriented programming theory , j2ee guideline and modern model design pattern . although the solution provides some function modulations which are tailored to the requirement of feng feng mine bureau , it could be served as an integrated solution to mine companies 本文从峰峰矿务局现有物资供应系统出发，借鉴先进的物流管理思想，详细地分析了峰峰矿务局现有物资供应系统存在的种种缺陷，并根据面向对象的软件程序设计思想，采用模块化设计将系统分成多个子系统和功能模块；采用j2ee规范搭建了一个多层分布式应用系统框架；采用设计模式构建了一个易维护、可扩展、稳定性高的系统结构，并遵循统一软件开发过程( rup )开发了适合企业自身特点的物资供应管理信息系统。
