The low spectrum utilization and the recombination of photo-generated electrons are the main challengesfor improving the performance of dye sensitized solar cells（DSSCs）. In this article, a three-dimensional flower-likeruffle titanittm dioxide（TDF-TiO2. was successfully synthesized via a simple sol-thermal process. X-Ray diffractionpatterns（XRD） and scan electron microscopy（SEM） images exhibit that the TDF-TiO2.are the futile TiO2.microspherecomposed of lots of regular cuboid nanorods. Applying this TDF-TiO2.as light scattering layer on the photoanode ofDSSCs, the devices present an excellent photovoltage performance, yielding a power conversion efficiency（PCE） of7.69%, which can be mainly attributed to the enhanced light utilization and the reduced recombination of pho-to-generated electrons upon a combined analysis of electrochemical impedance spectroscopy（EIS）, open-circuit vol-tage decay（OCVD）, and intensity-modulated photocurrent spectroscopy and intensity-modulated photo voltage spec-troscopy（IMPS/1MVS）, etc. As a conclusion, TDF-TiO2.is a potential material as light scattering layer and opticaltransition medium to improve the performance of DSSCs, and this work further demonstrated that regulating themorphology and particle size of TiO2.is an efficient approach for enhancing the performance of DSSCs by optimizingthe utilization of light and the transporting behaviors of photo-generated electrons.

To explore the possibility of absorption of lanthanides via digestive duct and their effects on one membrane structure and permeability of erythrocytes, the fine structure of erythrocyte membrane from Wistar rats, fed for 70 days of daily administration per os with 2. mg CeCl3.kg weight, was imaged by means of atomic force microscopy and FT-IR deconvolution spectra. The results show that, although the erythrocytes maintain the intact shape, the change OT secondary structure, aggregation and crosslinking of the protein particles of membrane surface and the enlarged lipid regions lead to the domain structure formation. This structure might be responsible for the increasing permeability of erythrocyte membrane.

DORMANCY-BREAKING potato tubers will germinate at suitable temperatures. It is a commonknowledge that germinating potato tubers are toxic. It has also been known that the seriouslytoxic compound named solanine, which exists abundantly in the green-turning parts of thepotato tubers, is the main cause of this toxicity. But it is still unknown what causes food poi-soning after eating the parts of dormancy-breaking potato tubers that have not turned *** a previous report we have shown that the operation of the cyanide-resistant respiration path-way during aging process of the slices from dormancy-breaking potato tubers is stronger

利用模拟降雨装置,研究了演替恢复初期不同植被覆盖以及不同处理下坡面降雨的产流过程和入渗率。实验研究结果表明,植被演替开始之初,由于地表土壤的土质比较疏松,土壤的入渗率比较大。随着植被演替的进行,土壤中有机质等物质的逐渐累积,土壤的理化性质发生了变化,土壤的入渗特征也随之降低。剪草降雨小区的实验研究结果说明,在降雨的初期,土壤的入渗性能相对较低,随着实验的进行,在雨滴的打击下,部分结皮被破坏,土壤的入渗率也随之增大。说明地表生物结皮的存在,降低了土壤的入渗性能。采取适当的措施破坏地表生物结皮,有利于提高土壤的入渗性能,增加干旱半干旱地区对降雨的利用程度。

EXTENDED SELF SIM ILARITY OF PASSIVE SCALAR IN RAYLEIGH-BNARD CONVECTION FLOW BASED ON WAVELET TRANSFORM

引用

Transactions of Nanjing university of Aeronautics and Astronautics 2001年第Z1期18卷 47-49页

作者： Fu Qiang 1,2. Xia Keqing 2. ( 1) College of Science, PLA university of Science and Technology Nanjing 2.0016,P.R.china) ( 2. Department of Physics, The {2. university of Hong Kong, Shatian, Hong Kong,P.R.china)

Wavelet transform is used to analyze the scaling rule of temperature data (passive scalar) in Rayleigh Bénard convection flow from two aspects. By utilizing the method of extended self similarity (ESS), one can find the obtained scaling exponent agrees well with the one obtained from the temperature data in a experiment of wind tunnel. And then we propose a newly defined formula based on wavelet transform, and can determine the scaling exponent ξ(q) of temperature data. The obtained results demonstrate that we can correctly extract ξ(q) by using the method which is named as wavelet transform maximum modulus (WTMM).

A comprehensive thermal analysis of the Phase change random memory （PCRAM） by 3. finite element modeling is proposed. The impact of thermal on device cell design and optimization is investigated. Such an analysis can be used as a guideline for the optimum design. This manuscript provides an insight into the thermal issues and the phenomena in the PCRAM. Refined structure, ring in GST structure （RIG）, is proposed for high density and low power consumption.

Systematic mass spectrometric 2.0}Th ages are reported for a Ponies coral reef terrace from Dengloujiao, Leizhou Peninsula, South china Sea. Seven episodes of coral growth were recognized in this terrace: 712.±96, 6764±2., 582.±3., 5006±54, 2.43.2., 1915±15, and 1513.2. calendar years before present (cal. aBP). 50% of the coral age popula-tion fall between 72.0 and 6600 cal. aBP, marking post-glacial stabilization of global sea level. Considering the facts that (i) Dengloujiao reef flat was measured at 1.6-2.5 m above modern tidal datum plane; (ii) modern Parties corals in the South china Sea are living at least ~1 m below the modern tidal datum plane; (iii) the top 2.-3. cm of the reef was eroded; and (iv) crustal subsidence in the region since mid-Holocene was negligible, we conclude that the above age groups record at least two major periods (72.0-5000 and 2.00-1500 cal. aBP) of high sea-level at least 2.9-3.8 m above the present-day level.
