Results: the best extracting condition for ellagic acid was to add 8 times amounts of the water solution of 1 mol/l hydrochloric acid, and to reflux for 60 min and extract twice.

结果：鞣花酸的最佳提取工艺为用1 mol/l的盐酸水溶液、8倍量、回流提取60 min、提取2次；结论：溶剂类型对鞣花酸的提取率影响最大，本研究确定的鞣花酸提取工艺合理、可行。

In this process, the electrolylic bath with cationic exchange membrance and leas electrode is used. The cathode liquor is oxalic acid, the anode liquor is diluted sulfuric acid. The process above has following advantages with high yield, top quality, lower cost, no "three wastes" pollution, and no oxalic aldehyde in the product. It is a cleaner and environment-friend technology, and is a development trend for production of glyoxalic acid. Complete analytical process for raw materials, intermediate and final products were established.

本论文通过对乙醛酸合成路线的研究，确定了草酸电解法制乙醛酸的工艺路线，此法采用装有阳离子交换隔膜和铅电极的电解槽，阴极电解液为草酸溶液，阳极电解液为稀硫酸，该工艺具有产品收率高、质量好、成本低、无三废污染、产品中无乙二醛等特点，是一条清洁、绿色工艺，是生产乙醛酸的主要发展方向。

The dissociation constants p K HL1 is in the range of 3\^50 to 4.89, p K HL2 6.17 to 8.38, K HL1 / K HL2 is below 10 5, which is consistant with the results of potentiometric titration curve. The Cu 2+ complexation constant,is 1.346 for old manured loessal soil and 2.241 for dark cultivated loessal soil.A good optimization result is given by nonelectrostatic model.

胡敏酸的解离常数和Cu2+的络合常数应用计算机程序FTTEQL32表明，优化的解离常数pKHL1在3.50-4.89之间，pKHL2在6.17-8.38之间，2种形态一元胡敏酸解离常数之比小于105，与滴定曲线只有一个突跃区相一致2种土壤胡敏酸与Cu2+络合常数logKintACu大小分别为土HA1.346，黑垆土HA 2.241，非静电模式的优化结果较好。

Phosphorus presented in crops such as grains, beans, oil-bearing crops is in the form of phytate-phosphorus. The utilization rate of phosphorus in phytate by monogastric animals was very low because of the lack of phytase.

在动物饲料中富含磷的谷物、豆类和油料等作物中，磷的基本贮存形式是植酸磷，因单胃动物体内缺少能分解植酸的酶很难利用这些植酸中的磷，其利用率极低。

Highly ordered SBA-15 sieves have been successfully synthesized in a low concentration liquid inorganic acid medium via the addition of small amounts of phosphomolybdic acid.

通过在低浓度无机液体酸介质中添加少量磷钼酸，成功地合成了高度有序的SBA-15介孔分子筛。N2吸附-脱附、XRD、TEM和水热稳定性实验等检测结果表明：用这种方法不仅可以大幅度降低合成SBA-15分子筛所需液体酸的用量和缩短晶化时间，同时反应产物SBA-15在100℃的水中处理72h后仍然保持六方有序的介孔结构
