The intramolecular proton transfers of phenol hydroxyl group to quinonoid carbonyl in Elsinochrome A are very sensitive for the change of molecular structure.

痂囊腔菌素A的酚羟基与醌羰基之间的分子内质子传递对其的结构变化最为敏感。7。

Unlike X-rays, the standard radiotherapeutic tool, a proton beam can be tuned in a way that causes it to dump its destructive energy at a particular depth beneath the skin.

不同于X射线这种标准的放射治疗手段，质子束的强度是可以调节的，，它可以在皮下一个特定的深度集中释放具有杀伤力的能量。

Unlike X-rays, the standard radiotherapeutic tool, a proton beam can be tuned in a way that causes it to dump its destructive energy at a particular depth beneath the skin. This means it can destroy a tumour without damaging other tissue.

与标准的放射治疗手段—— X 射线不同，质子射线的强度是可以调节的，待进入皮下特定的深度之后才一次性释放杀伤性能量，这说明它可以在破坏肿瘤的同时不会造成其他组织的损伤。

This study is a new effort to meet the great need of preparing alcohol rejective proton exchange membranes.

本论文正是以此为背景，旨在开发高性能阻醇质子导电膜方面进行一些新的探索和尝试。

This is the vintage 1984 Marantz turntable with Shure V15-III cartridge and the Proton DP1200 amplifier.

这是1984年经典马兰士转台与舒尔V15 -三墨盒和质子DP1200放大器。

Proton exchange membranes based on polyacrylonitrile /silica composites doped with heteropolyacids such as phosphotungstic acid or silicotungstic acid were prepared by sol-gel method.

采用溶胶－凝胶法制备了杂多酸掺杂聚丙烯腈－二氧化硅(PAN-SiO2)复合质子交换膜，并研究了其质子导电性能、保水能力和抗化学氧化性能。

This Ph.D. thesis describes further studies on theformation of fluorinated phosphorus ylide-anions resultingfrom organometallics and their reactions, stereochemistry andapplications in organic synthesis. We found that inverse stereochemical results wereobserved in the reaction of the fluorinated ylide-anions withvarious proton donors.

本博士论文进一步研究了用有机金属试剂对含氟膦叶立德的亲核加成导致的叶立德阴离子的反应性、立体选择性及其在有机合成中的应用：首次发现含氟叶立德阴离子在与不同的质子化试剂作用时，反应呈现完全相反的立体化学结果。

E. metabolic uncoupler with a lower pKa value has a higher potential to reduce sludge production which confirmed the theoretical analysis that uncoupler weaken the proton motive potential producing ATP.

连续40d的分批运行结果表明，3.6mg/l TCS能降低污泥产量54.3％，而基质的去除能力没有受到影响，出水的总氮和氨氮浓度和对照相当。

Valinomycin, a photophosphorylation uncoupler, decreased significantly the fast phase (related mainly to the membrane electric potential) millisecond delayed light emission of C. reinhardtii. Nigericin, another photophosphorylation uncoupler, decreased the slow phase (related mainly to the proton gradient) and partly also the fast phase of ms-DLE. Both valinomycin and nigericin can decrease the net ATP content under light and photosynthetic rate of C. reinhardtii, but the degree of inhibition of net ATP content and photosynthesis by nigericin was higher than that by valinomycin.

光合磷酸化解联剂缬氨霉素显著降低衣藻毫秒延迟发光的快相，对慢相影响不大；另一个光合磷酸化解联剂尼日利亚菌素则显著降低衣藻毫秒延迟发光慢相（主要与跨膜质子梯度有关），同时也降低部分快相。valinomycin和nigericin均可降低光下藻细胞中的ATP净含量和光合作用速率，但是nigericin对ATP含量和光合作用速率的抑制程度比valinomycin强。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。
