Firstly properties of the HJ SDF are revealed, and some useful conclusions are obtained. Then by the HJ SDF's properties and the two fund separation theorem, the mean-variance spanning is investigated and the spanning condition is gotten. It is proved by the mathematical method that the spanning condition gotten from HJ SDF is equivalent to the spanning condition gotten from the other methods.

Up to date, QTL analysis of adult-plant resistance against powdery mildew has not been reported in China. In the present study, QTL mapping of APR was conducted using a doubled-haploid population derived from the cross (Fukuho-komugi × Oligoculm) and a F_(2:3) population from the cross (Bainong64 × Jingshuang16). The methods and main results are described as follows:1. A doubled-haploid population from an intervarietal cross between the Japannese cultivar Fukuho-kumugi and the Israeli wheat line Oligoculm was prouduced by means of wheat × maize crosses.

In particular, it is unknown how the relevant neural substrates function as a network to mediate perspective-taking during the task requiring understanding other's belief. The current work first developed a new psychological paradigm that excludes potential confounds such as the processing of language, biological motion, episodic memory and causal coherence in the paradigms used in previous studies. I recorded neural activities associated with mental inference task using functional magnetic resonance imaging and electroencephalography in order to investigate the functional roles of several brain areas (i.e. precuneus, MPFC, etc.) that engage in understanding other's belief. I also proposed a computational model based on the neuroimaging results that simulated the neurocognitive mechanism underlying cortical dynamics in correct judgment of other's belief.

Results The diagenetic grade of Permian rift basin was quite high, and the mechanical compaction resulted in the great loss of the original pore. The eodiagenesis and telodiagenesis were important to the reservoir, and fractures were the dominant hydrocarbon migrating pathway and accumulating space; In Triassic-Paleogene Formation, mechanical compaction was as important as pressolution, and the most original pore was preserved. The exodiagenesis stage of late hercynian movement, indosinian movement and Yanshan movement played the vital role in the diagenetic evolution and hydrocarbon migration and accumulation of the basin. The argillaceous dolomite and algal dolomite discaved in Permian, which were formed probably by hybrid process in high salinity lake which had the fresh water interfused in.
结果 二叠纪裂谷盆地的成岩强度大,以机械压实作用为主,原生孔隙丧失多且早,晚期成岩作用较重要,裂缝是油气运聚的通道和空间,可出现次生孔隙发育带;三叠纪-古近纪拗陷盆地的成岩作用表现为机械压实和化学压实作用并重,原生孔隙多被保留;晚海西、印支、燕山运动等表生成岩阶段对该区的成岩演化和油气运聚起到重要作用;二叠系中特征的泥云岩和藻云岩可能是在有淡水注入的较高盐度湖泊中经混合作用而形成的。

As pH value varied in the course of diagenesis,reservoirs experienced one to three cementations or dissolution generations.Lots of secondary dissolution pores developed in the late diagenetic stage,because of the acidic mediums in the process of generation and migration of oil and gas. The anhydrites deposited in the dissolved pores resulted in the heterogeneity of secondary pores.

In order to confirm this suspect, we choosed a cultured rat granulation tissue fibroblasts model in vitro and applied RT-PCR and cell-ELISA technology to detect the changes of firbroblasts intrinsic EGF, bFGF, TGFβ-1 with their receptors gene expressions and protein synthesises after stimulated by SP. Our purpose was to explore the possible effects and patterns imposed by SP on fibroblasts intrinsic growth factors and their receptors expressions, which maybe offer theoretical basis for promoting wound healing via improving nervous functions and regulating neuropeptides secretions.
