ABSTRACT In this paper, some problems in harmonic free electron lasers and plasma wave wiggler FELs are investigated. The applications of FEL in material science are discussed in detail. As an example, KrF excimer laser was used to investigate the a-Si: H thin film solar cells instead of the free electron laser.

In this case, the solidification of the liquid phase formed at the hipping temperature led to the formation of crystalline intergranular phases at all temperatures: however, the chemical compositions of the intergranular phases formed in the specimens with and without carbon additions were different, since for high carbon contents the resulting intergranular phase was observed to be richer in Yttrium(85% at Y/15% at Si).

在这种情况下，加压温度下液态产物的凝固在所有温度范围下都将生成间粒晶体：但是，是否添加了碳则将会使产物晶体的化学成分发生不同，因为在高碳含量下，产物晶体会更富含钇(85%Y比15%Si)另一方面，我们必须强调的时，如果Al2O3作为第三方物质加入反应混合物粉末中，那么产物晶体的结晶度将被破坏。

用热分析技术分析亚共晶Al-Si合金的凝固过程，发现样杯模数、样杯结构是影响其凝固过程特征的主要因素。

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。
