The variation features of the Antarctic sea ice (Ⅱ)

In this paper, on the basis of the Antarctic sea ice data from 1972 to 1989 issued by the America JointIce Center, the distribution features of the Antarctic sea ice is analyzed, the net sea ice area indexes are calculated,and the long-range variation periods of the sea ice area index are analyzed with the maximum entropy spectrum, finally the distribution pattern of the Antarctic sea ice and its variation features are obtained.According to its spatial distribution feature, the Antarctic Sea ice is divided into three large regions. Region Ⅰ(0°～120°E) is a zonal area which includes the Prydz Bay area, and sea ice area extending from the Weddell Sea,Region Ⅱ (120°E～120°W) mainly includes the Ross Sea area, and Region Ⅲ (120°W～0°) mainly the WeddellSea area. Of all the regions, the ice area in Region Ⅲ is the largest, and that in Region Ⅰ is the smallest.In the Antarctic,the seasonal changes of the sea ice are very obvious, during summer, in February, there isleast sea ice in the Southern Ocean, the net sea ice area (not include the area of open water) is about 3 190 000 km2,during winter, in September, there is most sea ice in the Southern Ocean, the area index is about 16 840 000 km2,nearly 5. 3 times of that in February. The seasonal change of sea ice is one month lag of the changes of the air temperature, but almost synchronous with that of SST.Of all the three regions divided above, there are some points both common and uncommon in their sea icechange cycles, the common features are that there exist one and a half years, one year and ten-months secondaryperiods in all three regions, but their main periods are not the same, they are about 5, 11 and 6 a in Regions Ⅰ,Ⅱ,and Ⅲrespectively. The main periods of the sea ice change in Regions Ⅰand Ⅱ are very close because the ice areaextended eastward from the Weddell Sea ice area of Region Ⅲ is one of the main components of the Region Ⅰ. It isalso worth pointing out that in Region Ⅱ, southward extension of the Pacific Ocean, there exist not only a 11-yerasmain period but also a 2-yeras secondary period, which does not exist in the other two regions.

The variation of the Kuroshio during 1986-1988

On the basis of the analysis of the data obtained from five cruises of the R/V Xiangyanghong 09 and the data from Japan, it is shown that a large meander of the Kuroshio appeared again during 1986-1988. The processes of formation , maturity and decline of this large meander are discussed in this study. The variation of the volume transport at Section Kb (PN) in the East China Sea is related to the large meander of the Kuroshio in the area south of Japan. By using maximum entropy spectrum analysis,the volume transport of the Kuroshio and the swing of its axis are analysed and their major periods are obained.

Analysis on the Application of Campus Catchword Variation to Guiding the Teaching and Leaming of College English from the Perspective of Memetics

Along with the development of new media such as film and television, the phenomenon of language variation has sprung up in the world. The variation of campus catchwords not only meets the demand of college students, and also expands with a great influence to the development of the modern Chinese language. In this paper, the application of campus catchword variation to guiding the teaching and learning of college English from the perspective of memetics is discussed and also the related reasons are analyzed.

A new interpolating method based on the variation of spectra energy using CMOS array

A new interpolating method to enhance the resolution of gratings using complementary metal-oxide semiconductor （CMOS） according to the variation of soIne specified spectral light intensities during the motion of scale grating in a periodic separation is proposed. CMOS image sensor （pixel array 648 × 488） was also introduced as receiving device and its stability was verified experimentally. Many factors m the experiment were analyzed theoretically and contrasted with experiment. The advantages of this novel method were featured by CMOS and the specified spectral variation of the energy distribution was discussed.

Whither East-West Comparative Literature? One Recent Answer from China

Comparative literature,as a discipline,has been in selfdoubt and crisis since its birth.Various scholars give different answers to its tendency and future.With the growth of East-West comparative literature research in East Asia,Chinese School of Comparative Literature proposed its own answer to it.In response to James St.André’s review essay'Whither East-West Comparative Literature?Two Recent Answers from the U.S.',this paper focuses on a new answer from Cao Shunqing’s work The Variation Theory of Comparative Literature,aiming to explore the two focuses of this new platform:one is the heterogeneity,and the other is the variation,which are different from French comparatism based on influences and American part based on analogies.On this basis this article tries to have a dialogue with imagology study of variation theory and sinicization of Western literary theory in Cao’s works.By highlighting the heterogeneity and variation,Chinese scholars seek to promote crosscivilization communication based on maintaining and developing the uniqueness of different literatures and civilizations,thus building a harmonious world without uniformity.
