Homogeneous or heterogeneous base material is selected; an alternately superimposed barrier layer and an alternately superimposed recessed layer are grown and formed at the extension of the base material; donor impurity and acceptor impurity are doped in the interface between the barrier layer and the recessed layer and in the interface between the recessed layer and the barrier layer, and the p type group III nitride material doped at a position selecting superlattice is obtained.

选择同质或者异质的基质材料；在基质材料上外延生长形成变换叠加的垒层和阱层，在垒层与阱层的界面和阱层与垒层的界面掺入施主杂质和受主杂质，得选择超晶格位置掺杂的p型III族氮化物材料，其中，每个生长周期的步骤为：生长带隙较宽的垒层，同时掺入受主杂质；生长施主杂质或受主杂质δ掺杂层；生长非掺的带隙较窄的阱层；生长受主杂质或施主杂质δ掺杂层；在N 2 气氛下对所得的选择超晶格位置掺杂的p型III族氮化物材料退火，即得目标产物。

So it is assumed that the E-box might be associated with the enhancement of transcription activity.Here, the LTRs of WH17 ,DLA-25,DLA-118 and LTR with single mutation in the E-box motif were separately cloned into pCAT-Basic vector resulting in a series of recombinant plasmids containing CAT reporter under the control of different versions of LTRs.

通过对EIAV分离株WH17的LTR与L株、DA和DLA株的LTR序列进行比较，发现其在在U3-R结合处多一个E-box基序，推测该基序的变化可能会起到促进转录作用，为此将EIAV强毒株(DLA-25)、驴白细胞弱毒株(DLA-118)、EIAV分离株WH17以及U3-R结合处的E-box基序点突变的LTR分别克隆到pCAT3-basic质粒中的报告基因氯霉素乙酰转移酶的上游，获得一系列受不同LTR控制的CAT表达质粒。

Two days after bone marrow MSCs compounded to nano-CS/COL scaffold, bone marrow MSCs presented globular shape and were scattered; Four days later, bone marrow MSCs presented shuttle shape, extended and anchored on the surface of nano-CS/COL by pseudopods; Eight days later, bone marrow MSCs proliferated and fused each other, and they secreted a lot of extracellular matrix, then which covered most material particles.
