The experimental results showed that, monochloroacetic acid and dichloroacetic acid enhanced photocatalytic hydrogen generation activity, but trichloroacetic acid did not improve it. The amount of produced H_2 increases almost proportionally to the irradiation time within 5 h irradiation. The photocatalytic oxidation of monochloroacetic acid and dichloroacetic acid mainly produced CO_2, HC1 and CH_2O, the photocatalytic oxidation of trichloroacetic acid mainly produced CO_2 and HCl.

The structure analysis indicates that the reverse symmetry ligand H4LB molecules are linked into a 2D supermolecular network by two types of hydrogen bonds. One type occurs between the oxalamide oxygen group and the phenol hydroxyl qroup of the nearest molecule with d=2.906(2) and ∠O-H…O=151.8°. The other type is between the oxalamide nitrogen group and the oxalamide oxygen group of anther molecule with d=2.849(2),∠N-H…O=158.7°.

Because the temperature of coal volatile pyrogenation differs from the temperature of reduction of iron oxide by H2, H2 releases at the initial stages of reduction, and the reduction efficiency of hydrogen is very low.

由于煤中挥发分的热解析出温度与氢还原铁氧化物的还原温度不一致，氢在还原初期迅速放出，导致氢的还原作用率低；提高温度和加热速度可提高煤中氢的还原作用率和挥发分的利用率。

The activities of nitrate reductase, glutamate dehydrogenase and glutamine synthetase in water spanich leaves were enhanced, the contents of total nitrogen and protein increased, but the content of free amino acid decreased. Compared to the control, low and medium amount of quinhydrone made significant difference respectively, but high amount had not notable effects.

醌氢醌使蕹菜叶片硝酸还原酶活性、谷氨酸脱氢酶活性、谷酰胺合成酶活性、总氮含量、蛋白质含量提高，游离氨基酸含量降低；与对照相比，低、中量醌氢醌处理差异显著，高量醌氢醌差异不显著。

Effects of quinhydrone, as urease inhibitor, on growth, root activities, nitrogen metabolism, photosynthetic character, yield as well as quality were studied under pot experiment with water spanich and plot experiment with B.chinensis Var.comrtzunis. The results were shown as follow: 1. Applying low and medium amount quinhydrone promoted the growth of water spanich and B.chinensis Va,communis, whereas high amount treatment had little effect on water spanich growth, and inhibited the growth of B.chinensis Var communis.

以醌氢醌为脲酶抑制剂，蕹菜和小白菜为试材，研究了不同用量的醌氢醌对这两种蔬菜生长、根系活性、氮代谢、光合特性以及产量、品质的影响，结果表明：1 低、中量醌氢醌能促进蕹菜、小白菜的生长，高量醌氢醌对蕹菜的促进作用不大，对小白菜生长有抑制作用。

It was found that PCBA-BPy and PCCA-BPy exhibited both smectic and nematic phase while all of their predecessors showed no smectic phase.

结果表明，这两个氢键复合物都具有由于分子间氢键作用而导致的近晶相，但它们中存在的氢键作用却不相同，在PCBA-BPy中，温度变化时，发生氢键结合的羰基的吸收峰的位置仅在发生晶型转变时有突变，而在PC-CA-BPy中，温度变化时，其羰基的吸收峰的位置则基本不发生突变。
