| 1 | OSCILLATION CRITERIA FOR NONLINEAR SECOND ORDER ELLIPTIC DIFFERENTIAL EQUATIONS显示文摘The second order elliptic differential equations are considered in an exterior domain Ω Rn, n≥2, where p can chang sign. Some new sufficient conditions for the oscillation of solutions of (1.1) and (1.2) are established. | ZHANG BINGGEN ZHAO TAO B. S.

| 16 | Expression of the mouse metallothionein mutant ββ-cDNA in the lettuces (Lactuca sativa L.)显示文摘Mouse metallothionein (MT) domain mutant ββ-cDNA gene has been inserted into the plant expression vector pGPTVd35S which has herbicide (PPT)-resistance gene bar as a selective marker. The chimeric gene was introduced into the lettuce (Lactuca sativa L. cv Salinas 88) by Agrobacterium-mediated transformation. PCR and Southern blot analysis of some putative transformants indicated that the introduced ββ-cDNA was integrated into lettuce genome and inheritted by sexual reproduction. The expression of ββ gene in lettuce plants was demonstrated by Northern and Western blot analysis. Meanwhile, the zinc content of the transformed lettuce plants is up to 400 μg/g dry weight, remarkably higher than the control plants. | Zuo Xiaofeng Zhang Yukun Wu Beibei Chang Xing Ru Binggen | 2002 | Chinese Science Bulletin2002，47，7： | 1 |

| 20 | Durability of Green Concrete in Severe Environment显示文摘In this paper,the effects of different mineral admixtures and sulfate solution types on the appearance,mass change rate,relative dynamic elastic modulus,and corrosion resistance coefficient of concrete were systematically studied.X-ray Diffraction(XRD),Mercury Intrusion Porosimetry(MIP),Scanning Electron Microscopy(SEM),and X-ray Computed Tomography(X-CT)were used to explore and analyze the changes in the microstructure and the corrosion products of concrete in the sulfate solution.The results show that the existence of magnesium ions accelerates concrete deterioration.There is a critical dosage of fly ash for magnesium sulfate resistance of concrete.The magnesium sulfate resistance of concrete is improved when the fly ash content is less than 20%.Slag can significantly improve the corrosion resistance of concrete to magnesium sulfate.The diffusion of sulfate ions into concrete is a gradual process.In the early stages of corrosion,sulfate ion content in the concrete immersed in the magnesium sulfate solution is slightly less than that of the concrete immersed in the sodium sulfate solution.However,in the later stage of corrosion,the sulfate ion content in the concrete immersed in the magnesium sulfate solution is significantly higher than that of the concrete immersed in the sodium sulfate solution. | Yonggan Yang Zihao Kang Binggen Zhan Peng Gao Qijun Yu Yanlai Xiong Jingfeng Wang Yunsheng Zhang | 2023 | Journal of Renewable Materials2023，11，4： | 0 |
