In addition, there was an activity evaluation on TiOa thin film using HA as handle objects. The results showed that TiO2 thin film had a good effect on degradation of HA, and the degradation rate could attain to 52.9% in three hours which was 18.2% higher than that of direct photolysis, but when compared to the TiO2 aqueous suspensions, the degradation rate of TiOa thin film was a little lower.

Since both of the suppression on P5CS and PDH down regulated copper entry, the mechanism of blocking copper entry could be related to the utilization of proline instate of the proline level only.

由於抑制P5CS或PDH基因均可使脯胺酸的利用降低，显示铜逆境下脯胺酸的增加阻挡铜进入植体之机制，可能与脯胺酸含量无关而是与脯胺酸的利用有关。

67Ga-or 68Ga-DOTA-glutamine is apparently not a mimicker of glutamine or glutamic acid and its use as tracer needs to be reevaluated.

镓－67/镓－68-DOTA-麸醯胺酸显然不是合适的麸醯胺酸和麸胺酸的类似物，所以利用镓－67/镓－68-DOTA-麸醯胺酸作为肿瘤造影剂仍有很大的改进空间。

Pt-inserted nanotube titanic acid was prepared as follows: H_2PtCl_6 ethanol solution was filled into the titanic acid nanotubes and then annealed in air at 673 K for 3 h.X-ray photoelectron spectroscopy showed that H_2PtCl_6 has been converted to Pt~0 and PtO.The result of electron spin resonance revealed that there are single-electron-trapped oxygen vacancies to be formed in PNTA after heat treatment in air.

通过在真空条件下将氯铂酸的乙醇溶液引入到钛酸纳米管内，再经过热处理制备了镶嵌铂的纳米管钛酸。X射线光电子能谱表明氯铂酸大部分转变成Pt0和PtO，顺磁共振谱表明在PNTA中生成了束缚单电子的氧空位，在紫外-可见扩散漫散射谱谱上表现出对可见光有吸收能力。

As one of the most important osmoregulation actor, firstly,Proline plays a keyrole in the osmotic potential adjustment in plant cells. Secondly, Proline can preventNaCl from damaging the structure of biomacromolecule in cells. Thirdly, the highdissolubility and non-rejection capability of Proline can enlarge the solution volumnof the cell, so the concentration of salt will be diminished in cytoplasm and the saltstress will be relieved. Forthly, the accumulation of Proline could prevent thedehydrolysis from sap cavity in cytoplasm. Fifthly, the synthesis of plant chlorophyllwill be diminished under the salt stress, but the Proline can provide request ofchlorophyll synthesis.

脯氨酸作为渗透调节剂对植物体细胞渗透势的变化起重要作用：一，在盐胁迫下，脯氨酸在植物体内是一种重要的渗透调节剂，它是一些高等植物和绿藻抗盐和抗旱的主要渗透剂之一；二，脯氨酸可以保护细胞中的生物大分子的结构，使之不被NaCl破坏，并能维持其完整的水合范围；三，脯氨酸的高度溶解性以及其对植物各种酶活性不抑制性，可以扩大细胞的溶解容积，从而降低细胞质液中盐的浓度，减轻盐的胁迫作用；四，细胞质中积累的大量脯氨酸可以防止液泡对细胞质的脱水作用；五，在盐胁迫下，植物叶绿素的合成受到抑制，叶绿素的合成需要脯氨酸。
