可改革的

Recently, using solid clay brick is gradually prohibited, so the new wall material is required to fill up the new architecture. Many sections research on this field, using fly ash to develop new building materials is the mostly adopted method, among the new building materials, fly ash foamed concrete is a noticeable one because of its outstanding merits such as light weight, heat preservation, sound insulation and good resisting earthquake. Using fly ash to develop foamed concrete can not only become fly ash into resources, but also provide a new kind of building materials for the innovation of wall materials, which has good economy and society benefits.

近年来，由于墙改&禁实&政策的实施，市场急需新的墙体材料来填补新建筑所需，许多单位相继开展了各有关研究，综合利用粉煤灰研制开发新型建材逐渐成为了主流，其中多孔混凝土特别是粉煤灰发泡混凝土，正以它突出的轻质、保温、隔音、抗震效果好等优点，成为一种引人注目的建筑材料，利用工业固体废弃物粉煤灰研制发泡混凝土不仅能实现粉煤灰的资源化，而且还可为墙体材料的改革提供一种新型建筑材料，具有较好的经济效益和社会效益。

For a long time it has been operated mainly under a passive protection --"the limited protection", which highlights protection and dispises using,thus hinderes the development of the life and production within the ruins, and limites the function of the site to play a greater role.

汉长安城遗址长期实行以&限制型保护&为中心的单一被动保护模式，这种重保护、轻利用的方式阻碍了遗址内居民生产、生活的发展，限制了遗址功能的发挥；另外随着城市建设速度和遗址外改革步伐的加快，对遗迹本体保护及遗址环境安全造成了一定的冲击，因此如何协调遗址保护与利用的关系、实现遗址可持续发展成为亟待解决的问题。

So it is very urgent to set up a useful teaching-model of self-regulated learningThere are two-aspect meanings about the studies:1 to set up the physics teaching-model of self-regulated learning in senior middle-school can promote the research of theory and practice in self-regulated learning, enrich the study content of self-regulated learning and provide a choice for the reform of physics class-teaching method.2 to put the model into practice can raise the students ability of self-regulated learning.

本研究的意义在于： 1结合高中物理教学实际、高中生的心理特点，建立有效的高中物理&自主学习&课堂教学模式，可促进自主学习理论与实践的结合； 2通过对自主学习过程各种因素、各个方面相互关系与协调发展的系统研究，将在一定程度丰富自主学习的研究内容，推动自主学习理论与实践的发展； 3&自主学习&课堂教学模式的实施，将增强学生学习的自主程度，提高自主学习能力，促进学生物理学习方式的转变；并为推进素质教育，改革传统物理课堂教学提供了一条新的途径和选择。

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。
