Being divided into three groups-strong, moderate and weak-according to the different kinetic parameters (Fmax, km, Cmin) of potassium uptake by crops, 21 cultivars of rice have been studied to find out the relationships between their potassium nutrition and the oxidation-reduction status in the rhizosphere *** show that, with no application of K fertilizer, there were higher contents of active reducing substances and ferrous iron in rhizosphere soils planted with cultivars, such as Zhongguo 91, week in absorbing potassium than in soils cropped with cultivars, Shanyou 64, stronger in absorbing potassium. As a result of K application, however, these toxic substances were decreased appreciably in the soil, particularly in the root zone where weakly K-absorbing cultivars were growing, and the parameter of soil redox (pH +pE) was increased, the most striking example of this being found in the rhizosphere soil where the more strongly K-absorbing cultivars were growing. On and close to the root surface in soils where rice plants were supplied with potassium fertilizer, rather more iron oxide had been accumulated compared with rice receiving no potash, and even greater amounts of red iron oxide precipitated on the rice root in neutral paddy soils. As shown by the concentration distribution of active reducing substances and ferrous iron in a microzone of the profile, the redox range of rice roots supplied with potassium may extend as far as several centimeters from the root surface. It can thus be seen that potassium nutrition exerts its effect first on the morphological properties of rice roots and their exudation of oxygen, then on the content of soluble oxygen and the count and species of oxygen-consuming microbes in the rhizosphere soil, and finally on the redox status of the soil.

以组合式铝蜂窝为研究对象,通过改进SHPB系统,利用激光光通量位移计和PVDF压电薄膜测试技术,得到了铝蜂窝结构大应变低速压缩应力应变曲线;结合高速摄影分析了组合式铝蜂窝结构在低速撞击条件下的变形响应方式和吸能特性过程.结果表明,组合式蜂窝结构动态吸能可分为蜂窝嵌入过程和结构共同压溃两个阶段,对于厚度相同的两级组合式铝蜂窝结构这两个阶段的转换变形应变约为0.5,嵌入阶段所吸收的能量占总吸能比约为25%;组合蜂窝结构的吸能效率曲线存在两个相当的峰值,约为40%.与准静态结果对比,动态加载条件下,组合式蜂窝结构吸能效果更好.

研究目的:对定级指数确定后的农用地级别划分的常用方法进行比较分析,为农用地定级工作的开展提供借鉴。研究方法:统计分析法,实证研究法。研究结果:(1)数轴法仅适用于定级单元数较少时的级别划分;(2)定级指数频率曲线法所分级别,随着组数n逐渐增大而增加,到一定程度后可分级别将保持不变;(3)定级指数频率曲线法和等间距法划分级别存在的差异仅限于一个级别;(4)定级指数频率曲线法对于定级指数区间中值附近的单元,划分的土地级别较为准确;(5)采用等间距法,级别内单元数量较为平均,可划分的级别数量决定于组距;(6)等间距法对分布于定级指数较高或者较低的定级单元划分的级别较为准确。研究结论:3种常用的级别划分方法适用的条件和参数选择均不同,应根据定级指数的具体情况,选择合适的级别划分方法。
