Results showed that the kinetics of photocatalytic degradation of ethylene by TiO2/ACF desoposited Pt in the simulated cold storage environment for horticultural products could be described using the pseudo first-order equation. The prepared TiO2/ACF-Pt, in the process of which Pt was initially deposited on the surface of ACF and then TiO2 was coated, would promote the activity of ethylene decomposing. When ion sputtering time was 60 seconds (Pt/Ti atomic concentration ratio was 0.112), the apparent rate constant of the reaction of TiO2/ACF-Pt was 1.16 times as much as that of TiO2/ACF. The micrographic structure of ACF was not damaged and an excessive porous structure, which was contributive to absorbing the diluted ethylene, was obtained by the way of ion sputtering Pt.

结果表明：在模拟园艺产品冷藏环境中，TiO2 /ACF-Pt光催化降解乙烯的动力学可用表观一级速率方程来描述；ACF表面先溅射沉积Pt，再进行TiO2附着方案，能提高降解乙烯的能力，当溅射时间为60 s（Pt/Ti原子浓度比为0.112）时，表观一级速率常数是未溅射Pt的1.16倍；TiO2/ACF-Pt的制备方法，对ACF形貌结构没有破坏，并能得到有利于对微量乙烯的吸附的多孔结构。

According to the change of the kinds of elements content in slag, F in slag volatilizes in the form of KF and NaF, KF volatilizes much more easily than NaF, KF plays a leading role in the F volatilization, theoretical analysis shows that the saturation vapour pressure of KF in the test slag is 31. 4 times of NaF; when F content is far more than K, KF volatilization is first order grade reaction, it is dominated by K content, the apparent activate energy is 275. 30KJ/mol.

4依据对含氟熔渣中高温条件下（1450℃、1505℃）的各种元素含量的变化情况，发现氟在熔渣中是以碱金属氟化物挥发，并且，KF比NaF具有更好的挥发性，在氟的挥发中占主导地位，理论研究也证明，在1505℃试验组成的熔渣中，KF的饱和蒸气压是NaF的31.4倍；在含氟量远大于钾含量的情况下，KF挥发为一级反应，受钾浓度控制，其表观活化能为275.30KJ／mol。

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。
