An analysis of the influencing factors and mechanism of tourist revisiting willingness by adopting the multiple regressionmodel based on the survey data obtained from 581 valid questionnaires concerning Kaiping Diaolou and Villages reveals that the maininfluencing factors of revisit intention are ： tourist spot image, cognitive attitude, tourists＇ expectation and satisfaction. Of the fourmain factors, tourists＇ cognitive attitude is the direct influence factor, and the image of the sites and tourists＇ expectation indirectlyinfluence the revisit intention through tourists＇ satisfaction. This research result provides a new approach to the market developmentfor the heritage villages.

Learning motivation occupies an important position in non-intelligence factors,as it plays a pivotal role in university students' successful completion of their studies and strengthening of professional knowledge base.However,the present university students generally lack motivation in higher education.This research used questionnaire method,which is a questionnaire random sample in 500 students of learning motivation from four comprehensive higher vocational colleges of Tianjin,and explores the status quo of learning motivation in higher vocational students of Tianjin.The result shows:The learning motivation level of higher vocational colleges students is above middle level;Male on the learning motivation total level is significantly higher than female;Rural students in the learning motivation on the aggregate level is significantly higher than that of urban students;Look from the different grades,sophomore students have lowest level of learning motivation;Freshmen learning motivation is at highest level.

Assam of the northeastern region of India is unique in terms of its rich biodiversity and multiple ethnicity of its people. The impact of the resultant socio-religio-cultural diversity is also reflected in the diverse traditional ways of silkworm farming. We report the genetic diversity of Persea bombycina “Som” from different locations of Goalpara district of Assam, India, where random amplified polymorphic DNA (RAPD) marker was used in this study. RAPD analyses of ten genotypes of “Som” from Goalpara district of Assam, India with B19 RAPD primer generated 86 bands, showing an average of 8.6 bands per sample and 30.2% (26 bands) of these were polymorphic. The number of bands per accession ranged from 5 to 10 with a mean of 8.6 and the size range of the amplified bands was 250 - 6000 bp. In a UPGMA phenetic dendrogram based on Jaccard’s coefficient, the P. bombycina accessions showed a high level of genetic variation, as indicated by genetic similarity and revealed 10 “Som” genotypes in to three major clusters. This study may be useful in identifying diverse genetic stocks of P. bombycina, which may then be conserved on a priority basis. The RAPD primer used in this study was able to distinguish all the 10 genotypes of “Som” plants, which can be used to assess genetic diversity.

The U-Pb (on zircon) and Sm-Nd analysis is a popular isotope-geochronological tool for estimating the age of rocks from PGE mafic-ultramafic intrusions. Sulphides can be used to study the geochronology of ore processes as well, since they should indicate the time of ore mineralization. Gabbronorite has been sampled from the Passivaara reef at the Penikat layered intrusion (Finland) for U-Pb and Sm-Nd isotope single zircon analyses in order to separate sulphide minerals. The Sm-Nd isotope age of gabbronorite has been dated at 2426 ± 36 Ma;eNd(T) = −1.4 ± 0.4. The Sm-Nd isotope age on sulphides and rock-forming minerals reflects the crystallization time of the ore-bearing gabbronorite from the Passivaara reef of the Penikat layered intrusion. The mass-spectrometer analytical environment and modes of operation have been adjusted to detect REE in sulphide minerals on example of pyrite from the PGE Penikat layered intrusion (Finland) and chalcopyrite from the Talnakh deposit (Norilsk area, Russia) has been estimated. The total REE content in pyrite is ca. 3.5 ppm, which is enough to define the Sm-Nd age of pyrite. The study shows how to use the mineral/chondrite spectra to evaluate the accuracy of the REE analytical results on example of State Standard Sample 2463 (Russia).

两千年来古人语法分析说略(下)

It is believed that in ancient China,there were only works on graphology,phonology and critical interpretation,but no works on grammar.In works of grammar history published in modern times,they just dwell briefly on ancient grammar,and they consider that there were only some explanations of form words,a few books of form words,but no syntactic analyses.However,in fact,in ancient classical works there were abundant materials of grammatical analyses.Ancient scholars worked out quite a few grammar rules,some of which were profound and coincidental with modern grammar theories.In the present research of ancient Chinese grammar,grammatical analyses made by ancient scholars should be summed up and inherited.

Determining the timing, magnitude, and location of deformation due to the Indo\|Asian collision is widely acknowledged as an important step in understanding how the lithosphere responds during continental collision. Thus a puzzling result of geological investigations of the Lhasa Block over the past two decades has been the apparent lack of significant Tertiary deformation there. Perhaps the most important structural feature of the Lhasa Block is the south\|directed Gangdese Thrust System, which developed along its southern edge. The thrust system, which separates the Andean\|type batholith of southern Asia from rocks of Indian affinity, is obscured at most locations across southeastern Tibet by backthrusts of the younger, north\|directed Renbu Zedong Thrust System. The best documented site where both thrusts are exposed is a structural window near Zedong.
