研究结果还显示，双桥山群变质泥质岩的Pb-Pb等时线年龄为（1 490±68）Ma，而障公山群、双桥山群、程浪群和修水群的钕模式年龄分别为1.57 Ga、1.89Ga、1.77Ga和1.60 Ga，均分布在1.5～1.9 Ga之间，表明这些地层的形成年龄应小于1.9 Ga，是中—晚元古代的产物，同时表明扬子古陆南缘存在古元古代的基底。

Considerating over-all performance of mag nets, it was concluded that the optimal amount of doped-Ga was 0.5wt%. The other was that the grains size distribution of grains was narrow and grain distributed homogeneously as to microstructure of magnets when the amount of doped-Ga was 1 .Owt%;(3 ) In the magnets, there existed not only Nd2Fei4-xGaxB, but also GaNd concerning the Ga-elment form. The GaNd increased the amount of liquid and had favorable function during sintering, so it made for the increase of magnets density and the form of the second phase is good for improving coercivity.

综合考虑磁体的性能，最终得出添加0.5wt％为最佳的Ga添加量；(2)对于Nd_(15)Fe_(78)B_7+Ga系永磁体，当Ga的添加量为1.0wt％时，得到颗粒粒度分布范围窄，颗粒分布较均匀的显微结构；(3)元素Ga在磁体中不但以Nd_2Fe_(14-x)Ga_xB形式存在，而且以GaNd的形式存在，在烧结的过程中，增加了液相的数量，起助烧结的作用，有利于磁体密度的提高，形成第二相有利于矫顽力的提高。

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。

Here is something we often say:'There are many good restaurants in tokyo', in japanese its 'to-kyo ni wa i res-to-ran ga ta-ku-san a ri-mas', translate it back to english, it roughly means 'tokyo in wa good restaurant ga many there-are-inanimate (wa and ga are both particles that follow the pronoun; a-ri-mas is used for inanimated objects or things).

我们常说这句话：&在东京有很多好的餐厅&，用日语说是&to-kyo ni wa i res-to-ran ga ta-ku-san a ri-mas&，将它翻译回英文，它的大致意思是东京在wa好餐馆ga许多都死气沉沉的（wa和ga都是跟在代词后的虚词；a-ri-mas 用于无生命的物体或东西）。

Combined with available data, it is comidered that the sourcerock of biotite--leptynite might be intermediate-acid volcanic material of ca.2.7 Ga, and that of migmatized leptite and quartzite might come from granitic crust older than 3.0 Ga. The iron formation was formed on the continental crust base at about 2.7 Ga, and was immediately metamorphosed for the first time.

结合已有的研究资料可以认为，黑云变粒岩的原岩来自2.7 Ga左右的中酸性火山物质，浅粒岩和石英岩的原岩来自3.0 Ga以上的花岗质地壳物质；含铁建造形成于陆壳基底之上，形成时间约2.7 Ga，并于2.5—2.7 Ga之间发生首次变质作用。

Sulfur isotope measurements of deposits such as those in the 1.1 Ga Duluth Complex, the Per-mo-Triassic intrusions of the Noril'sk area, and the 1.4 Ga Kabanga intrusions provide evidence for the derivation of S from both sulfide-and sulfate-bearing country rocks. The 1.3 Ga Voisey's Bay deposit provides an example where δ^34 S values of the ores commonly fall within the accepted mantle range of 0±2‰, but detailed studies of Proterozoic metasedimentary country rocks show that their weighted average δ^34 S value is also within this range.
