We suggested that the surface and framework around secondary pores were dissolved by KOH solution, then reinsertion of aluminum into the framework vacancies of EDY occurs.

在没有外加铝源的情况下， KOH溶液也可以铝化EDY样品， KOH溶液首先溶解EDY表面相及二次孔周围的沸石骨架，然后这些溶解下来的铝碎片再填充到EDY的骨架空位中去，致使其Si/Al比降低。

Excitation-Emission Matrix Fluorescence Spectroscopy was employed to study fluorescence characteristics of chromophoric dissolved organic matter readily released from sediment particles during episodes of resuspension, and bottom waters and surface sediment pore waters were compared in all corresponding sites.

对采自厦门湾九龙江入海河口的4个沉积物样品进行了室内再悬浮模拟实验，利用荧光激发－发射矩阵光谱研究了再悬浮过程中从沉积物中释放出的有色溶解有机物的荧光特征，同时通过与相应站位沉积物间隙水和底层水的对比分析，探讨了河口近岸海域的沉积物再悬浮作用作为水体中溶解有机物来源之一的可能性。

However, it did speed up the dissolution in the prepassive range, changing oscillation behaviors of iron in 0.5 mol.dm-3 H2SO4. The reactivation process of passivated iron was mainly determined by the electrode potential, and had little to do with the external magnetic field. The investigation also proves that holographic microphotography is a very effective technique in the study of effects of the magnetic field on the electrochemical processes.

外加磁场对铁的活化溶解没有明显的影响，但加快了预钝化区铁的溶解，从而显著改变铁的电化学振荡行为；钝化铁再活化过程主要取决于电极电位，与外加磁场没有关系；研究表明全息显微术是磁电化学研究中一种十分有效的方法。

The welding nugget happened to dynamically recrystallize and the refined crystal grains were obtained and the majority of Mg_2Si particles dissoluted due to the intensive mechanical stir and higher high temperature. In the thermal-mechanical affect zone that was heated under the recrystallized temperature, the crystal grains were elongated due to the mechanical stir and Mg_2Si particles partly dissoluted and the others grew. In the heat affect heat without the mechanical stir, to some extent, both of the crystal grains and the majority of Mg_2Si particles grew.

焊核区受到强烈机械搅拌作用和加热到较高的温度发生动态再结晶，得到细小等轴晶组织，Mg_2Si相以溶解为主；热机影响区加热温度低于再结晶温度，在机械搅拌作用下晶粒由于塑性变形而伸长，Mg_2Si相部分溶解，部分长大；热影响区仅受加热影响，晶粒有一定程度长大，Mg_2Si相以长大为主。

Though there're plenty of UPs and DOWNs, we'll get the confidence to redissolve even if we're nothing but precipitation!

即使坎坷不平，我们也要保持自信：总有使沉淀再溶解的办法！

He dissolution mechanism of α-TCP cement may be considered as dissolution and reprecipitation of defective calcium hydroxy-apatite hydrated from α-TCP.

CP骨水泥固化体在生理盐水中，溶解动力学方程为：y=-ln(1-x)=kt〓；溶解活化能为9.87kJ/mol，其机理是α-TCP水化形成的缺钙羟基磷灰石溶解再沉积的过程。

The invention uses the fermentation liquor of one Escherichia coli generating polysialic acid as material, filters and removes thallus, adds some solvents as sodium chloride and alcohol into supernatant to deposit polysialic acid, dissolves the polysialic acid deposits via deionized water, filters to remove modified protein, uses alkali prolease to treat filtrate, complexes deposits via cetyl pyridinium chloride or cetyltrimethylammonium bromide, and dissociates, uses over alcohol to deposit polysialic acid, dissolves the deposits via ultra-pure water, grades and purifies via chromatography column, collects and dialyzes eluent, cools and dries to obtain polysialic acid.

本发明以一株产聚唾液酸大肠杆菌的发酵液为原料，经过过滤去除菌体，上清液加入适量氯化钠和乙醇等溶剂沉淀出聚唾液酸，聚唾液酸沉淀用去离子水溶解，再用过滤去除变性蛋白质，滤液经过碱性蛋白酶处理、氯代十六烷基吡啶或十六烷基三甲基溴化铵络合沉淀并解离后，再用过量乙醇沉淀出聚唾液酸，聚唾液酸沉淀用超纯水溶解，用层析柱进行分级纯化，收集洗脱液经过透析，冷冻干燥得聚唾液酸产品。

The results showed that the dopes of many kinds of waste fibers re-solution were mixed with the system, the dope PAN content and rising-bubble viscosity should be selected as 12%～13%, 70～100s, thus the effect of waste fiber on fiber quality was minimum.

结果表明，各种废丝再溶解成的原液按一定比例投入系统后，控制此原液总固含量在 12 %～ 13%，升泡粘度在 70～ 10 0s时，对纤维质量影响最

Thus, too cerebral infarction patients, must be the doctor's advice and timely basis of the factors for cerebral thrombosis formal system of treatment, the only way to effectively prevent the recurrence of cerebral infarction, in particular, is suffering from cerebral infarction, in the effective melting suppository within the time (6 ~ 24 hours), timely treatment, thrombolysis, recanalization, since the view that patients return to normal, often because of financial, human and other factors, eager to hospital after reperfusion, non-systematic formal and effective cause of treatment, which led to the repeated recurrence of cerebral infarction, regret.

因此，得过脑梗塞的病人，一定要遵医嘱，及时针对脑血栓形成的基础因素进行正规系统的治疗，只有这样，才能有效地防止脑梗塞的再发，特别是患脑梗塞，在有效溶栓时机内(6~24小时)，及时治疗，血栓溶解，血管再通，自认为恢复正常的病人，往往因经济、人力等因素，再通后急于出院，不进行系统正规的、有效的病因治疗，而导致脑梗塞的反复再发，后悔莫及。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
