1Modern sedimentation rates in the intertidal zone on the west coast of the Bohai Gulf显示文摘On the basis of the measurement of 210Pbex and 137Cs activities in the sediment cores taken from the intertidal zone on the west coast of the Bohai Gulf, the average sedimentation rates of modern sediments are calculated. The results indicate that in the sandy area of the intertidal zone (from Daogouzi to the Duliujian River), the sedimentation rate from 1955 to 1963 is 3.43-4.06 cm/a, and is within the range of 0.65 ̄1.59 cm/a since 1963. The average sedimentation rate in the muddy area (around Qikou) is approximately 1.81 cm/a. The results above suggest that the sandy area of the intertidal zone has experienced rapid sedimentation from the 1950s to the 1960s, and the sedimentation slows down after the 1960s, and the sedimentation rates increase from north to south spatially. The rapid sedi- mentation from the 1950s to the 1960s in the sandy area is due to the fact that North China has plentiful precipitation during this period and the intertidal zone is supplied with abundant matter sources for sedimentation. After the 1960s, the weakened sedimentation may be a result of the reduction of sand transported to the intertidal zone, which is a consequence of diminished rainfall in North China and intensive human activities in the Haihe basin.MENGWei LEIKun ZHENGBinghui WANGFu WANGHong LIJianfen LIYong 2005Acta Oceanologica Sinica2005,24,3:15
2Structural and photocatalytic properties of TiO_2 films fabricated on silicon substrates by MOCVD method显示文摘Silicon(111) and Silicon(100) were employed for fabrication of TiO 2 films by metal organic chemical vapor deposition(MOCVD). Titanium(IV) isopropoxide(Ti[O(C 3H 7) 4]) was used as a precursor. The as deposited TiO 2 films were characterized with FE\|SEM, XRD and AFM. The photocatalytic properties were investigated by decomposition of aqueous OrangeⅡ. And UV VIS photospectrometer was used for checking the absorption characteristics and photocatalytic degradation activity. The crystalline and structural properties of TiO 2 film had crucial influences on the photodegradation efficiency. For MOCVD in situ deposited films on Si substrates, the photoactivities varied following a shape of “M': at lower(350℃), middle(500℃) and higher(800℃) temperature of deposition, relative lower photodegradation activities were observed. At 400℃ and 700℃ of deposition, relative higher efficiencies of degradation were obtained, because one predominant crystallite orientation could be obtained as deposition at the temperature of two levels, especially a single anatase crystalline TiO 2 film could be obtained at 700℃.YANGJia-long LIYing WANGFu ZUOLiang Gu-ChulYi WongYongChoi 2005Journal of Environmental Sciences2005,17,1:3

9Fabrication and Photocatalytic Characteristics of TiO_2 Films on Silicon Substrates显示文摘Silicon (111) and Silicon (100) have been employed for fabrication of TiO2 films by metal organic chemical vapor deposition (MOCVD). Titanium (Ⅳ) isopropoxide (Ti\[O(C3H7)4\]) was used as a precursor. The as-deposited TiO2 films have been characterized with Field emission scanning electron microscopy(FE-SEM), X ray diffraction (XRD) and atomic force microscopy (AFM). The photocatalytic properties were investigated by decomposition of aqueous orange Ⅱ. The crystalline and structural properties of TiO2 film had crucial influences on the photodegradation efficiency. For MOCVD in-situ deposited films on Si substrates, the photoactivities varied following a shape of “M”: At lower (350 ℃) middle (500 ℃) and higher (800 ℃) temperature of deposition, relative lower photodegradation activities have been observed. At 400 ℃ and 700 ℃ of deposition, relative higher efficiencies of degradation have been obtained, because one predominant crystallite orientation could be obtained as deposition at those two temperatures, especially a single anatase crystalline TiO2 film could be obtained at 700 ℃ growth.YANGJia-long WANGFu ZUOLiang YIGu-chul CHOIWong-yong 2005Wuhan University Journal of Natural Sciences2005,10,3:0

11Studies on Anthocyanin in Purple Flower of Helichrysum bracteatum显示文摘This paper puts forward a biochemical analysis of the anthocyanins in the petals of Helichrysum bracteatum flower which takes a deep purple color. A pure antho-cyanin chloride crystal is obtained and identified as a cyanin glucoside by IR, UV and MS techniques. This paper also presents a study on the preservation mechanism of the flower color and flower shape according to the histochemical and anatomical characteristics of the petals.Yang Shaoyong Wu DixinDepartment of Landscape Gardening ,Beijing Forestry University Bi Wangfu Cao YuyingExperimental Center of For.

12Dually flat general spherically symmetric Finsler metrics显示文摘Dually flat Finsler metrics arise from information geometry which has attracted some geometers and statisticians. In this paper, we study dually flat general spherically symmetric Finsler metrics which are defined by a Euclidean metric and two related 1-forms. We give the equivalent conditions for those metrics to be locally dually flat. By solving the equivalent equations, a group of new locally dually flat Finsler metrics is constructed.Xiaoming Wang Wangfu Liu Benling Li 2018Science China Mathematics2018,61,4:0
