A series of Cu(II)-, Zn(II)-, Co(II)-loaded zeolites were successfully prepared by liquid phase ion-exchange method and characterized by X-ray diffraction(XRD), N2-adsorption specific surface area measurement(BET), X-ray fluorescence(XRF), and scanning electron microscopy(SEM) techniques. The adsorptive desulfurization performance of different adsorbents for treating Saudi Arabian medium crude oil was investigated, and the results showed that desulfurization efficiency declined in the following order: Zn(II)X > Cu(II)Y > Co(II)X > Cu(II)X > Co(II)Y> Zn(II)Y. The best desulfurization efficiency of 41.01% was achieved by using Zn(II)X as the adsorbent under the optimized *** desulfurization performance of Zn(II)X in different distillates showed that a better performance was obtained in heavy petroleum fractions. Furthermore, the distribution of sulfur compounds in distillates after desulfurization was analyzed and the results showed that the adsorbent Zn(II)X could preferably adsorb aromatic sulfides such as thiophenes,benzothiophenes, and dibenzothiophenes. These results suggested that the π-complexation between zinc ions and sulfides would be crucial to the excellent desulfurization efficiency of Zn(II)X. In addition, the used adsorbent could be regenerated by heating at 700 °C in air, and around 84% of desulfurization capacity was recovered after the first cycle of regeneration.

Interfaces of microlayers, in most stalagmites from China, consist of opaque and organic materials. Observed with microscope, the interfaces seem dark under transmitted light and luminiferous under reflected fluorescent light. Stalagmites in which the two optical characters are unified spatially would be most suitable for cross-dating use, and can play an important role in the study on speleochronology and speleoclimatology.

LonP1 Links Mitochondria–ER Interaction to Regulate Heart Function

作者： song linhua LIANG Fuyuan Institute of Geographical Sciences and Natural Resources,Chinese Academy of Sciences

＜正＞ This paper studies the CO2 distribution of soil atmosphere in the Shilin National Park. The measurement sites were chosen according to different topographic features and different vegetations. Seven measurement sites on 3 cross sections were chosen to pass through 3 karstic depressions or on the slopes of depressions. All measurement results show soils with pH values lower than 7.0 （from 5.4 to 6.6）. There are 2 cases for the pH values of soil in different topographic features: the pH values of 2 profiles on the ridges or upper slopes of depressions are lower than those in the depressions;and the pH values of 2 soil profiles on the slopes of depressions are higher than those in the depressions. Most samples show relatively low humidity and CO2 contents on the ridges or slopes of depressions compared with soil profiles in the depressions. High CO2 contents occur at depths from -40 to -80 cm and high and dense grassland shows high CO2 contents in the soil atmosphere. Grass roots may grow and are distributed mainly at depths from -20 to -40 cm;while tree roots predominantly as deep as -60 cm even -80 cm. The influences of pine, cypress and eucalyptus on soil CO2 have been studied. Soil CO2 influenced by pine and cypress are generally concentrated in an area surrounding the tree with a diameter of 1 m and the strongly influenced distance is 50 cm. Eucalyptus will strongly affect the CO2 contents in an area with a diameter of 2 m, especially 1 m distant from the tree. The highest concentration of soil CO2 at a depth of -30 and 100 cm from the tree reaches 92000 ppm.

Because of the development of tourist activities and the facilities in the show cave, the closed system of show cave has been changed into the complicated open system. The great number of the visitors and the landscape lights give great deal of thermoenergy to the show cave system, especially the high intensive lights make the temperature nearby goes up very fast and reduce the humidity. After the visitors leaving and the lights switching off, the temperature goes down and humidity increases even upto saturation, the condensation taken place. In the dry seasons, the cave humidity is relative low, even down to 40 50 percent. The administrations of show cave rushes the water to clean the touristic trails and keep the high humidity as to protect the cave environment. Under the function of artificial readjustment, the humidity of Yaolin cave atmosphere reaches to 97-100 percent throughtout the year.
