These results suggest that the diagenesis material of the Xiangshan volcanic intrusive complex was derived from crustal sources. The sources either had relatively lower maturity or had more juvenile mantle-derived igneous rocks than the exposed basement metamorphic rocks. Involvement of a small amount mantle-derived magma during the formation of the Xiangshan volcanic-intrusive complex was also possible. The diorite enclave, sub-quartzmonzonitic porphyry and lamprophyre were probably different mixing products between mantle and crust materals.

上述同位素示踪结果充分证实：相山火山-侵入杂岩的成岩物质主要为壳源，但与该区出露的基底变质岩相比，其物源区的成熟度相对较低或含有一定量的火成物质，并且不排除在其成岩过程中少量地幔物质的介入；闪长质包体、次石英二长斑岩及煌斑岩的成岩物质均含有一定量的地幔组分，可能为壳-幔混合作用的产物，只是受地壳物质混染的程度不同而已。

We didn\'t find activated points in cerebellum and deeper brain.3.Acupuncture of sham point can significantly activated BA2,6,8,13,21,37,40,44,45,47,putamen and other areas.Both the left and right side of the brain have activated points,but points on the right side are more than those on the left.Both sides of middle temporal gyms,parietal lobule,supramarginal gyms and the lentiform nucleus have obvious activated points.The activated points mainly concentrated in the cerebral cortex,the deep-activated are mainly in the putamen.4. Sham needling in sham point can significantly activate BA6, 8,9,10,18,21,37,40,43,44.The activated points are mainly distributed in the right side of the brain.The left side also has some activated points;5.In the comparasion of Acupunture and sham-needling in S J5,we find that BA8 and cerebellum have distinct regional activated points;6.In the comparasion of acupuncture in SJ5 and sham point,we find BA2 and left cerebellar regions have activated points;7.Sham needling in S J5 compared with sham point,we find BA7,8,9,18 and other areas have activated points,the main activated points are at the left brain.It is not difficult to find that the distribution of activated points are mainly in the middle brain,no obvious activated points at the temporal lobe.

From the Late Carboniferous to the Permian, Junggar region into the post-collision tectonic evolution stage, in the stage of the post-collision, the early subduction slab rupture and separate, asthenosphere decompression melting, basalt magma take place underplating, because the underplating of the basalt magma, low crust melt by the high temperature forming the acid crust-magma, the basic magma from mantle and acid one from crust mixing at the vicinity of the crust-mantle boundary, formed the Huangyangshan magma mixing plution, the dioritic microgranular enclaves are the recorder of the crust and mantal magma mixing process.

从晚石炭世到二叠纪，准噶尔地区进入后碰撞构造演化阶段，在后碰撞构造阶段，早期的俯冲板片断离，软流圈减压熔融，玄武质岩浆底侵至下地壳底部，底侵基性岩浆带来的巨大热量，导致地壳物质熔融，形成大规模的花岗质岩浆，两种岩浆在壳-幔边界附近发生不同程度的混合，其中闪长质微细粒包体就是基性的幔源岩浆和酸性的壳源岩浆不同程度的混合的记录者。

Furthermore, the experiences of artificial breeding and farming showed that different geographical populations of Meretrix clam are also substantially different in growth rate and the ratio of shell weight to soft-body one.

由于我国海岸线漫长、地形复杂，因长期地理隔离和生境不同，导致不同海域的文蛤在壳表形态和颜色、花纹图案等外观特征上均存在显著差异；另外，从多年的养殖实践中也发现，我国文蛤不同地理群体在生长速度、壳肉重比率等重要经济性状上也存在着显著差异，而这些性状的稳定性差异必然依赖于其分子遗传结构的变异。

Furthermore, out of 497 fAFLP markers, 80 special bands were found to be able to distinguish the four groups from each other and may be applied for germplasm characterization and molecular assistant classification of Meretrix clam.4 Molecular classification of two species of Meretrix clam based on fAFLP and ITS sequences4.1 The results of fAFLP maker analysis of S, G and W showed that each group had their own specific loci among which there were 53 special loci in W group, much more than those of S group (14) and G group (21). Among the 53 loci, nine were all dominant loci. These unique loci could be taken as molecular markers to distinguish W from other groups. The genetic similarity indexes and distance matrix between S and G groups were 0.9585 and 0.0424 respectively, but the genetic similarity indexes and distance matrix between W group and S or G group was 0.7939 or 0.7941, and 0.2308 or 0.2305 respectively. The results revealed that significant difference existed between W and S or G groups in molecular genetic structure. The phylogenetic trees by the methods of UPGMA and NJ also indicated that S and G populations were very closely related, while W population was a relatively independent cluster, lying beyond the species which S and G belong to.4.2 The internal transcribed spacer region of the rDNA from S group, G group and W group were PCR amplified and sequenced. The results showed that the size of ITS ranged between 1266-1269bp in W group, while those in G and S groups were 1614bp and 1520bp respectively. The GC content ranged 62.32-62.62% in W group while it was 61.77% in G group. The genetic distances between three populations of W group were 0.001～0.003, but it was 0.110 or 0.147 respectively between W group and G group or S group. Phylogenetic trees by NJ method also showed that G group was very closely related to S group, while W group was a relatively independent cluster.

在457个总扩增位点中找出了53个W的特有位点，远多于S群体(14)和G(21)群体，而且在53个特有位点中有9个出现频率为100%的位点，这些位点可以作为区分其它2个群体的特征性标记；S– G群体特有的位点有112个，其中有4个位点出现频率为100%，可作为S– G群体区别于W群体的特征性标记。S群体和G群体间的遗传相似性系数为0.9585，遗传距离只有0.0424，在NJ和UPGMA法构建的亲缘关系的树状图上均首先聚在一起，说明二者的亲缘关系很近，应属于种内群体间的关系；而W与S和G的遗传相似性系数均较小(0.7939和0.7941)，相对遗传距离很大而且十分相近(0.2308和0.2305)，在亲缘关系树状图上单独分出一支，也表明W与S和G群体间的亲缘关系较远。4.2 ITS序列比较分析通过对白壳文蛤、山东文蛤和广西文蛤的ITS序列扩增电泳、PCR-RFLP分析和ITS序列分析发现，W的ITS序列长度在1266-1269 bp，而S和与G的ITS序列总长度分别为1520 bp和1614 bp；从ITS1和ITS2长度来看，W分别为739-741 bp和316-317 bp，S为895 bp和414 bp，G为987 bp和416 bp；而从ITS碱基组成来看，W的GC含量在62.32-62.62%之间，而G群体为61.77%。W的3个壳色不同群体间的遗传距离仅0.001、0.002和0.003，S与G群体间的遗传距离是0.010，说明W群体内变异很小，而S与G群体间已出现明显的遗传分化，但还均属于种内群体间的遗传变异；而W与G和S的遗传距离分别达到0.110、0.147，两个类群差异显著，已远超出种内群体间的遗传变异。
