Previous studies on the grammaticalization of relative clause structures almost exclusively focus on the postnominal type because of the lack of authentic data on the development of the prenominal type.

以往对关系从句的语法化研究主要是集中在后置型关系从句上，原因在于对前置型关系从句的发展情况缺少真实的语料。

In this thesis, research on the grammaticalization of relative clauses is extended to the prenominal type typically represented by examples from Chinese which enjoys a privileged status of having a recorded history of over three millennia.

我们的母语汉语历史上所出现的关系从句主要是前置型的，这为我们开展这方面的研究带来了方便。本文将把关系从句的语法化研究推向新的领域，即把主要集中在后置型关系从句上扩展到前置型关系从句上。

the title compound was synthesized and its structure was studied in theory.the schiff base compound was synthesized by condensation of paeonol with furylfurylamine,then it was deoxidized by sodium borohydried.the energies,bound lengths,bound angles,the net charges of main atom and contributive percents of frontier orbital in the title compound have been calculated by software hyperchem 7.0 in half experience method.the yield rate of title compound was 65.6%.the result of calculation showed that the most of the bond lengths and angles in the system were in the the normal range,negative charge mainly concentrate on o1,o2,o3 and n1.the title compound behaves as quadridentate ligand.

目的合成标题化合物并对其结构进行了理论研究。方法以丹皮酚和糠胺为原料合成席夫碱，经硼氢化钠还原得标题化合物；使用hyperchem7.0程序，用半经验方法计算了化合物分子中能量分布、主要键长、键角以及主要原子的净电荷分布和前言轨道分布。结果标题化合物，收率65.6%；计算结果分析表明，分子中主要原子之间的键长、键角基本在正常的范围内；负电荷主要集中于o1，o2，o3和n1上。

Due to the exploitation and utilization of deep groundwater in northern Shandong plain, a lot of environmental problms have been occurred,such as,the regional deep groundwater depression is continuously enlarging,in some area,deep groundwater exhausted and water quality is becoming more and more saltish,as well as land subsidence was aggravated and endemic appeared in some major towns.The reason is that the groundwater exploitation is most concentrated in towns areamabd tge exploiting methods is much more irrational.

摘 要：鲁北平原在深层地下水开发利用过程中，由于开采地段过于集中在城镇，加上不合理开采等因素，出现了区域性深层地下水超采漏斗不断扩大、部分地段地下水资源枯竭和水质咸化问题严重、重点城镇地面沉降加剧及饮用高氟高碘地下水引发的地方病呈上升趋势等诸多水环境问题。
