The effective prediction space concept is established, On the base of these, this paper deduces two representations' evaluating equation, one evaluates the prediction error and the other evaluates the prediction error in limited space. First, the error transfer characteristic among subsystems at different space locations is analyzed, and the direct transfer characteristic from discrete standard measure space to the workpiece measure space under measured in measure system is proven. Second, the error reconstruction condition and method of mapping from discrete standard measurement system to continuous standard measurespace are analyzed.

In this study, a stress induction expression promoter of monocotyledon (P-WCS120) was amplified from wheat genome. The result of sequencing displayed a base substitution mutant of 1 bp and an insertion mutant of 21 bps. This sequence was registered at GENEBANK as a new found sequence, because 3% of the sequence was found to be non-homologous with the original sequence.

Results (1) The forward and reverse subtracted cDNA libraries of different metastastic potential large cell lung cancer cell lines were successfully constructed;(2) With blue-white colony and dot blot, 307 positive clones in the forward subtracted library and 78 positive clones in the reverse subtracted library were obtained;(3) 55 clones were successfully sequenced in the forward subtracted library. Homolog analysis confirmed 23 differential expression segments, which were similar to the human genes already known, including NME2, NPM1, MT 2A, HSPE1, TAFIA, EPRS, PX19 and EIF3S9 et al;(4) 31 clones were successfully sequenced in the reverse subtracted library. Homolog analysis confirmed 16 differentially expressed segments. 15 of them were similar to the human genes already known, including ANXA2, TUBB, PKN2, GNAS, EEF1A1, SSR2 and RPLPO et al. Only one segment had partial homology to known human genes. This segment was supposed to be the new EST segments which might not have been cloned.

In this study, EPMA and LA-ICP-MS were used to determine the major and trace element concentrations, respectively, of apatites from Transhimalayan granitoids. The results indicate that F, Mn, Sr and REEs in apatites generally show good correlations with compositions of their host magmas and thus have high potential to be utilized as petrogenetic tracers. More specifically, F and Mn contents in apatites are covariant with the aluminosity of the host rocks so that can be used as an indicator for magma differentiation. Combining with Sr and REE data, which show significant variations in apatites from different rock types, these elements may be furthermore used to construct "discrimination diagrams" for more detailed investigations of complex petrogenetic processes such as magma mixing and compositional heterogeneity.
本研究中,电子微探以及雷射烧蚀感应耦合电浆质谱术分别被用以量测藏南火成岩中磷灰石的主量与微量元素含量,微区分析的结果显示,磷灰石的氟、锰、锶以及稀土元素均与岩浆源成分展现良好的对比关系,揭示了它们应用在岩石成因示踪上的优秀潜力:其中,磷灰石氟、锰含量的变化与原岩的铝饱和情形息息相关,因此可以作为岩浆分异程度的指标;而锶以及稀土元素则在不同岩石类型来源的磷灰石中展现了明显的丰度变化,因此综合这些元素将有机会进一步建立岩浆来源的「鉴别图」,甚而以此讨论岩石成因,例如:岩浆混合与源区组成的不均一性。
