草酸

A porcelain like film with protective and ornamental function can be obtained by anodizing aluminum alloy in potassium titantyl oxalate acidic solution.

草酸钛钾法瓷质阳极氧化可在铝及其合金材料表面形成一层外观类似瓷釉和搪瓷的氧化膜，具有较好的保护、装饰性。

After the LB film of dipalmitoylphosphatidylcholine was treated by 2.5mmolL^(-1) potassium oxalate, the structural differentiation between liquid expanded phase and liquid condensed phase in LB film was strengthened and circular defects appeared.

经2.5mmolL^(-1)的草酸钾溶液对二棕桐酰磷脂酰胆碱的LB膜进行处理后，可强化LB膜中液态扩张相化E）和液态凝聚相之间的结构差异，原子力显微镜证实了圈状缺陷的存在。

Using titanium tetrachloride and titanium potassium oxalate as titanium source,and 4A zeolite, ZSM-5 zeolite and natural zeolite(which is produced from JinyunCounty of Zhejiang Province) as main materials, we prepared nano titanium dioxideand zeolite composite.

本文利用四氯化钛和草酸钛钾为钛源，4A沸石，ZSM-5沸石和浙江缙云天然沸石为主要原料，制备了纳米二氧化钛/天然沸石组装体系。

The small particles can act as nucleii for other materials such as carbohydrates, oxalates etc and grow larger.

这些微粒可能是一些糖类或草酸等原料的核子，而且他们还会变大。

Phytates, oxalates and phosphates present in plant foods can inhibit absorption, as can tannin in tea.

Phytates ，草酸盐和磷酸盐在植物性食品可以抑制吸收，可以在茶单宁。

The programmed calcination process is necessary, that is, heating the as-elutedhmmersed oxalates mildly from room temperature to 300℃at a heating rate of 5℃/min, and keeping the samples at 300 C for 1 h; consecutively, heating to 900℃at 10℃/min, and then keeping for 4 h.

程控的烧结过程是必须的，这就是，按5度/分钟逐步加热按这种淋洗制备的草酸盐到300度，保温1小时；接着，按10度/分钟加热到900度，保温4小时。

The characterization of rare earth compound powders,such as rare earth hydroxides,rare earth carbonates,rare earth oxalates and rare earth oxides,are important to the synthesis of rare earth new materials.

稀土粉体(氢氧化稀土、稀土碳酸盐、稀土草酸盐、稀土氧化物和氟化物等)的颗粒性能方面的指标对稀土新材料的开发具有重要意义。

The single phase Fe-Ni nitrides 〓〓 with different nickel concentration from x=0 to x=0.78 were successfully prepared by annealing the oxalates at appropriate temperatures in H〓/NH〓 gas flow.

文中给出了单相铁镍合金氮化物〓〓的详细的制备条件，并认真讨论了不同镍含量的铁镍草酸盐在热处理过程中的还原和氮化产物。

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。
