- Though zn 2 + and co 2 + are divalent ions , they probably can not substitute ca2 + from the active center of tcs , or can substitute ca2 + but does not change the structure of tcs . there is no significant change observed for the fluorescence intensity of tcs
‘ “是二价金属离子，但这两种离子与天花粉蛋白作用时可能并没有取代天花粉蛋白活性部位的ca ‘ ” ，或部分取代但并没有改变天花粉蛋白分子的空间结构，以致天花粉蛋白的荧光强度无明显变化。 - In the upper troposphere , there is no intact asian active center . the troposphere structure of summertime ao is implicated with the horizontal heterogeneity of air temperature throughout the whole troposphere with its center over asian continent , which results in the zonal asymmetry and baroclinic structure of the summertime ao ( especially its asian center ) . on the contrary , the correlation between wintertime ao and sea - land thermal contrast confines in the lower troposphere , hence its zonal asymmetry and baroclinity in the lower level
夏季北极涛动的这种结构与对流层整层的温度水平分布不均匀性有密切联系，且这种温度分布差异主要体现在亚洲大陆，因而也就使北极涛动的中纬度亚洲中心呈现出比同纬度带其它区域更为明显的纬向非对称性和斜压性；而冬季北极涛动受下垫面海陆分布差异影响，其纬向非对称型和斜压性质主要出现在对流层中低层，在对流层高层表现出很强的环形模态和正压结构。 - In contrast , the out - of - phase vacillation in summertime ao covers the arctic region and mid - latitude asian continent . though the summertime ao exists on intraseasonal as well as interannual time scale , its asian active center abates on the intraseasonal pattern , thus awarding it more conspicuous zonal symmetric structure . interannually , summertime ao exhibits the zonal asymmetric and baroclinic features , and its seesaw mode is significant only in the lower troposphere
在年际时间尺度上，夏季北极涛动表现出比冬季北极涛动更强的纬向非对称性和对流层高、低层位相不一致的斜压性，其极地中心和亚洲中心的反位相涛动关系在对流层低层比较显著，向上逐渐减弱，到对流层高层不能表现明显的亚洲中心。 - Crystal zirconium phosphate - phosphonate has the stability and regulity of interlayer floor of inorganic a - zirconium phosphate , they still have the designability of the organic group in the interlayer and adjustment of the ratio of organic and inorganic phosphorus acid , they are a kind of potential smart material , we can process molecule design and optimize filtration according to the requirement of goal reaction , we can prepare special ion - exchange , catalyst , catalyst supporters nonlinear optics compound , solid state proton conductivity and the intercalation complex precusor by introducing different active organic group or active center into the choice and stable framework of inorganic a - zirconium phosphate
有机?无机晶态混合磷酸锆具有无机磷酸锆的层板稳定性和规整性，同时具有层间有机基团的可设计性和有机无机磷酸混合配比的可调节性的特点，是一类很有潜力的灵巧材料，并且可以根据目标反应的要求进行分子设计和优化筛选，在无机磷酸锆优良稳定的骨架上引入不同的活性基团或活性中心，可以制备出性能独特的离子筛、催化剂、催化剂载体、非线性光学物质、固态质子导体和制备插层复合物的前驱物。
