Moreover , the medium film affected the coupling effect , weakening its leading effect on the microwave - absorbing properties of materials , increasing the absorption quantity and decreasing the matching thickness , the density of area and the lodb bandwidth 介质膜的加入则会影响层间耦合作用，减弱层间耦合作用对材料吸波性能的主导作用，提高吸收量，降低匹配厚度、面密度与10db带宽。
It was shown that the absorbing rate of hybrid rice and it restorer for store material and for photo - material was 50 % and 80 % respectively , and the absorbing rate of hybrid rice was a litter higher than that of its restorer 结果表明，杂交组合及其相应恢复系的籽粒对标记储藏物质及标记光合物质的吸收分别达到50 %和80 % ，杂交组合籽粒的吸收量高于相应的恢复系，但差异不大，说明在储藏物质与光合产物的运输方面，杂交组合比相应的恢复系之间无明显差别。
Additionally , the aba content of hyperaccumulators had risen dramatically with the growth of lead concentration , and the increase of aba content was sig the results showed that the lead contamination had negative ef fect even on the hyperaccumulators . 3 . lead uptake " " nd tolerance of hyperaccumulators 3富集植物对pb的吸收与耐性提出了表征富集植物pb吸收量与耐性的数量指标重金属迁移总量、根系耐性指数和耐性临界值的概念及其计算方法。
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。
Compared to the control , concentrations of cu and zn in e . splendens were significantly higher in the treatment of edds plus microbial product , and then markedly enhanced plant cu and zn uptake . edds application alone increased pb concentration in the above ground parts of e . splendens plants . the treatment of microbial product or chitosan alone had no significant effect on metal concentrations in e . splendens 发现3mmoll ~ ( - 1 )乙二胺二琥珀酸( edds )和微生物制剂的联合处理可以极显著地提高海州香薷地上部铜含量与积累量，同时也提高植物对铅、锌的吸收量，强化了复合污染土壤的植物修复作用。
Abstract : the synthesis , adsorptive properties and some other mechanical properties of a kind of high water - adsorbing fiber were studied , paper made from this high water - adsorbing fiber beaten with 80 % ( wt ) cotton , demonstrated that the fiber had rap id adsorption , high adsorptive capacity and holding capacity for all of distilled water , main - water and man - made urea , and had suitable mechanical properties to be used to make high water - adsorbing paper 文摘:本文报道了一种高吸水纤维的合成、吸水性能及其部分物理机械性能，并利用这种高吸水纤维与纯棉纤维按1 ： 4的比例进行混合打桨而制成一种高吸水纸，对这种吸水纸也进行了吸水性能及部分机械性能的测定，结果表明所合成的高吸水纤维对蒸馏水，自来水及人工尿液的吸附速度快，吸收量高，并且可在一定的压力下保持较高的吸水量，还可以与棉纤维混合成纸。
