  摘要：

  我们研究了高达14特斯拉的强磁场对血小板聚集过程的影响，并对比了有无静磁场的情况。使用兔血浆和胶原蛋白混合物作为受损血管的模型系统。通过激活酸溶性胶原蛋白来触发血小板聚集。在强磁场中的血小板聚集物比在自然环境场中的更大。在血小板聚集过程中，血浆的光学透射也表明强磁场增强了血浆中的血小板聚集。

  Isostructural behaviour in ammonium and potassium salt forms of sulfonated azo dyes

  摘要：

  The structures of five ammonium salt forms of monosulfonated azo dyes, derivatives of 4-(2-phenyldiazen-1-yl)benzenesulfonate, with the general formula [NH4][O3S(C6H4)NN(C6H3)RR′]·XH2O [R = OH, NH2 or N(C2H4OH)2; R′ = H or OH] are presented. All form simple layered structures with alternating hydrophobic (organic) and hydrophilic (cation, solvent and polar groups) layers. To assess for isostructural behaviour of the ammonium cation with M + ions, the packing of these structures is compared with literature examples. To aid this comparison, the corresponding structures of four potassium salt forms of the monosulfonated azo dyes are also presented herein. Of the five ammonium salts it is found that three have isostructural equivalents. In two cases this equivalent is a potassium salt form and in one case it is a rubidium salt form. The isostructurality of ion packing and of unit-cell symmetry and dimensions tolerates cases where the ammonium ions form somewhat different interaction types with coformer species than do the potassium or rubidium ions. No sodium salt forms are found to be isostructural with any ammonium equivalent. However, similarities in the anion packing within a single hydrophobic layer are found for a group that consists of the ammonium and rubidium salt forms of one azo anion species and the sodium and silver salt forms of a different azo species.
