In the 2A1 distorted trigonal bipyramid structure ,the single non equivalent Ga atom has the population of 4s 4p ,while the two equivalent Ga atoms have the population of 4s 4p .this compares with a Ga population of 4s 4p in the undistorted D3h structure ,hence the jahn-teller distortion causes depletion of the charge density on the 4s orbital of the non-equivalent Ga atom, and enhancement of charge density on the 4s orbital for the two equivalent atoms .an opposite trend is observed for the 4p orbitals of these Ga atoms .the P population for the two equivalent atoms is 3s 3p .the populations of the other 2B1 state with the edge-capped tetrahedral structure are similar with the exception that all three Ga atoms have similar but not identical populations .
在2A1被变形的三角bipyramid结构,唯一非等效Ga原子有4s 4p的人口,而二个等效Ga原子在未变形的D3h结构有4s 4p 。this的人口和4s相比4p的Ga人口,因此jahn出纳畸变在non-equivalent Ga原子的4s轨道导致电荷密度的取尽,并且电荷密度的改进在4s轨道为二个等效原子。an在趋向对面对这些Ga原子4p轨道被观察。the人口为二个等效原子是另一个2B1状态3s 3p 。the人口与边缘加盖的四面体结构是相似的P 除之外全部三个Ga原子有相似,但不相同人口。

In the exploitatation and utilization of Bromus stamineus, we must take the different sowing methods and plant densities into account. They have heavy influences on the forage especially in terms of the forage growth. The salt, temperature and water are important factors that affect the seeds germination,which deciding the germination time and germination place.we designed four temperature (15℃,20℃,25℃,30℃) and NaCl density(0.3%,0.6%,0.9%,1.2%) and PEG density(0.126g/gwater,0.186 g/gwater,0.232 g/gwater,0.270 g/gwater).

The AMF spore average density was 24.88 per 20 g soil , the species richness was 1.94 per soil sample, the species diversity index was 2.56, and the species evenness was 0.65. Glomus, but they all were of prominent genus in the investigation area and Acaulospora, Scutellospora were of common genus while Entrophospora was rarely found. In the 13 species AM fungi, G.mosseae was of prominent species, and G.geosporum, G.intraradices, G.etunicatum were of common speices, while the others were of rarely species. There were 87.5% sand fixation plant were infected with arbuscular mycorrhizal fungi, the highest spore density, the strongest infection strength of the whole roots and the best species richness belonged to Chenopodiaceae while Polygonacea was the lowest.
