Principal component analysis showed total microbial population can be an index to evaluate vegetation restored precess and soil quality.

近年来一些学者[5，6]对黄土丘陵区植被恢复后土壤质量演变进行了研究，取得了较为满意的结果，但大多研究集中于

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。

Compared to the sample without ultrasonic treatment, it was found that, for AZ31 magnesium melt alloy treated by ultrasonic, the refined grain size and the inproved distribution of grain with its shape of oval-shaped or spherical can be obtained, and the precipitation inside Al matrix was inhibited The Mg17 Al12 precipitates distributed mainly along the grain boundary and hardness was improved remarkedly.

通过对铁合金AZ31进行熔体超声处理发现，处理后试样的晶粒较未进行超声处理的试样有明显细化，分布均匀程度提高，形状呈椭圆状或球状，合金元素Al在晶粒内的析出被抑制，Mg17Al12第二相的析出主要集中于晶界，硬度有明显提高，并且通过试验确定出了最佳处理功率和时间，为超声波在铸造生产中的应用提供了依据。

This time, unlike other years, the goal was not to have an international conference with many coming from many countries, but to concentrate on the French speakers. 800 invitations were sent to recipients of Rhema books in the French language.

这次与已往国际特会不同的是，目标不是为了许多其它国家的参加，但是集中于讲法语的人。800份邀请函已经发出给雷玛所接触到的人。
