Chemically, fluoroquinlones are an amphoterics molecule processing major ionizable groups, a basic piperazine amine and acidic carboxyl. The form of drugs was greatly affected by the acidity in aqueous solution. Thus the effect of pH values in aqueous solution on the fluorescent properties of fluoroquinolones was studied in details, the spectral properties of each form was characterized. It was found that the fluoroquinolones exhibit weak fluorescence in strong basic solution.

氟喹诺酮类药物分子结构中既有羧基,又有哌嗪氨基,它们所处环境的pH值对其存在型体有很大影响,因此我们详细研究了水溶液的pH值对该类药物光谱特性的影响,并对于各型体光谱特征进行归属,发现强碱性溶液中其发光较弱。

The rocks are potassium-high (K2O=4.10%~5.27%, 4.86% on average) and alkali-rich (Na2O+ K2O=7.12%~8.24%, 7.85% on average) ones, and have an average K2O/Na2O value of 1.63, ACNK values of 0.90~1.05 (0.96 on average) and KN/A values of 0.71~0.89 (0.78 on average), thus belonging to metaluminous to weakly peraluminous granitoids of shoshonite series and K-high calc-alkaline series.

岩石高钾、富碱,K2O含量为4.10%~5.27%,平均4.86%;Na2O+K2O为712%~8.24%,平均7.85%;K2O/Na2O值平均为163;ACNK值在0.90~1.05之间,平均为0.96;KN/A在0.71~0.89之间,平均为0.78,属钾玄岩系列与高钾钙碱性系列准铝质-弱过铝质花岗岩类。

The sequence of effects of these three dispersants on the stability of ITO suspension is PVP>β-alanine>triammonium citrate, which is in agreement with the sequence of their acidity and alkalinity in the suspension.

结果表明:3种分散剂分散机制均为静电和空间位阻稳定作用;在相对ITO粉体质量比为5%、最佳球磨分散时间为48 h时,在15 d内ITO浆料的RSH可维持在10%以内;3种分散剂对ITO浆料稳定性的影响由强至弱的顺序为:聚乙烯吡咯烷酮>β-丙氨酸>柠檬酸三铵,与其在溶液中酸碱性强弱顺序一致,其中聚乙烯吡咯烷酮的分散效果最好。

只需15-20分钟,就能把中性的自来水和弱酸性的逆渗透水转化为碱性还原水。

For example, alkaline elements can affect diffusion velocity of Zr, Si and O ions although these alkaline elements cannot exist in crystal structure of zircon. However, K rich media and Na rich media exert different effects on the growth of crystal form: in the K rich media, growth speed of prism faces in the vertical direction is much higher than that of pyramid faces, and {111} growth speed in the vertical direction is higher than {311},which decides the formation of bipyramids dominated by {311} pyramids; in the Na rich media, both prism and pyramid grow to a certain extent, but the former is smaller than the latter.{100} growth speed in the vertical direction is lower than {110}, while {111} growth velocity in the vertical diredtion is lower than that of {311},resulting in the growth of the crystal form characterized by {100} short prism and {111} pyramid.

例如,尽管碱性元素并不进入锆石晶格,但它们可以影响Zr、Si、O离子的扩散速度,但是富钾和富钠的介质对锆石晶形发育的影响是有差别的,表现为:在富钾的介质中,将导致柱面的法向生长速度较锥面快得多,而锥面中,{111}的法向生长又较{311}快,由此决定了形成以{311}锥为主的双锥状晶体;在富钠的介质中,柱面和锥面都有一定程度的发育,但前者弱于后者,而柱面中,{100}的法向生长较{110}慢,由此决定了形成以{100}柱和{111}锥为主的短柱锥状晶体。
