采用DTA和吸附吡啶的FT-IR表征氯氧化锆的表面酸性，用Hamm ett指示剂测定其酸强度，以催化合成环己酮2，3-丁二醇缩酮为探针反应优化缩酮反应条件，并考察它对其他缩酮反应的催化活性，比较了不同催化剂对缩酮活性的影响。

In 2003,on the whole the soils in Wujiang were little acid, pH from 6.40±0.38 to 5.40±0.55now, and the trend of acid was in Tailake region. The available phosphorous in Paddyfield were significantly lower than. the other five land use patterns. As a result,controlling the phosphorous output form vegetable field mulberry yard and other dryland might be more significant to control the non-point pollution in Tailake region.

吴江市土壤基本上属微酸性土壤，2003年耕地监测中土壤pH值由1982年的6.40+0.38变为5.40±0.55，可见近20年来太湖地区普遍存在的酸化趋势；在稻田、林地、桑园、菜地、果园、旱地六种常见的土地利用方式中，稻田土壤速效磷显著低于其它五种利用方式中；因此，在控制太湖地区磷的面源污染上，控制菜地、桑园和其它旱地土壤磷的输出可能更为迫切。

Therefore, the adsorption capacity of the pancreatin hydrolysate onto activated carbon was higher due to its lower solubility of at acidic pH.

中文意思：所以，胰酶水解产物在酸性pH值条件下由于具有较低的溶解性而易于被活性炭吸附。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
