The harzburgite inclusions in western Liaoning could be relicts of partial melting of the mantle-derived peridotites; the amphibole-bearing spinel lherzolites could be representative of Phanerozoic accreted lithospheric mantle; the pyroxenite xenoliths with cumulate textures would be the cumulates of magma derived from asthenosphere in the upper mantle; the granulite and gneisses with crystalloblastic textures could be derived from the lower crust in the region.

辽西尖晶石方辉橄榄岩为地幔橄榄岩部分熔融的残留体；含角闪石的尖晶石二辉橄榄岩可能代表了显生宙新增生的岩石圈地幔；具有堆晶结构的辉石岩类包体为源于软流圈的母岩浆在上地幔顶部的堆积层；而具有变晶结构的麻粒岩和片麻岩类岩石包体则代表了本区下部地壳的物质组成，是岩浆上升过程中捕虏的深部地壳岩石包体。

The 43-57km lithospheric mantle could be consist of a suite of cumulates with crystalloblastic texture, cumulate texture and relic magmatic crystalline textures, such as orthopyroxenite, websterite, clinopyroxenite and olivine-pyroxenite. The lithospheric mantle of 43km to Moho discontinuity could be spinel harzbergite and minor spinel lherzolite, in which the spinel harzbergite and minor spinel lherzolite xenoliths are discoveried. The Moho in the region could be an transitional zone composed of cumulates in petrology.

The equilibrium P-T conditions of the spinel lherzolite xenoliths in the study area are: T=913~1045℃, P=13~22kb corresponding to depths of 45~83 km. The P-T conditions suggest that the geothermal gradient of the upper mantle beneath the study area is approximately similar to oceanic geotherm which may be caused by asthenosphere upwelling.

本研究尖晶石二辉橄榄岩之平衡温度大致介於913℃1045℃之间，平衡压力则介於13kb~22kb，深度大约介於 45km~75km 之间，其温压范围大多接近於大洋地区之地温梯度，此相对较高之地温梯度可能与软流圈之上涌有关。

Heat flows derived from garnet, chromite/chromium-spinel and pyroxene of xenoliths, xenocrysts in Mengyin and Fuxian kimberlites are higher than 40mW/m〓 calculated from the pyroxene inclusions in diamonds, and the range of pressure is 20～40kb (equivalent to 65～130km). Metasomatism (as indicated by yimengite and lindsleyite in Mengyin) is very strong in this depth range. Lherzolite, wehrlite, and diamond-free high-Ca harzburigite around the world are derived from this depth also. The observation suggests that the low-Ca harzburigitic environment for diamond stability had been changed significantly when the kimberlitic magmas erupted. This resulted from fluid interaction with harzburigite. The geotherm of the Cenozoic lithospheric mantle beneath Eastern-North China platform is higher than oceanic one. The temperature from the interior of the Tan-Lu faults is higher than that from apart off the fault.

除金刚石中的辉石温压投点落于40m W/m〓占地温线上外，捕虏体及捕虏晶中石榴石，铬尖晶石及单斜辉石的投点均偏离该地温线，显示较高的地温特点，而且捕虏体及捕虏晶的压力范围多在20-40kb(相当于65-130km)间，该深度范围内地幔的交代作用特别发育，如蒙阴大量发育的沂蒙矿、钛钾铬石等就发育于该深度范围，世界范围内不含金刚石的高钙方辉橄榄岩、二辉橄榄岩、异剥橄榄岩也分布于该区中，一方面表明捕虏体的主要取样位置已不在金刚石稳定区中，另一方面也表明金刚石稳定的橄榄岩环境，在金伯利岩侵位并捕虏他们时已发现了明显的改造，这种改造作用主要是通过长期的熔流体与先存的橄榄岩相互作用的结果。

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。
