Evolution of a Water pendant Droplet: Effect of Temperature and Relative Humidity

引用

Natural Science 2017年第1期9卷 1-20页

作者： Etienne Portuguez Arnaud Alzina Philippe Michaud Maksoud Oudjedi Agnès Smith Université de Limoges SPCTS CNRS ENSCI Limoges France Université de Limoges ENSCI Limoges France

As part of a better understanding of drying liquids within porous materials, measurements from 293 to 343 K of deionized water surface tension in air as a function of relative humidity are exposed. Experimental work was carried out using the pendant drop method coupled with image analysis within an adapted instrumented climatic chamber. Results show that surface tension linearly decreases when relative humidity increases. Although the effect of humidity is less compared to that of the temperature and even less compared to a surfactant impact, it must not be neglected and values have to be mentioned when dealing with water evaporation. Modifying surface tension also affects the pendant drop shape. The drying kinetics of the pendant drop volume and its outer shell are connected to this change of shape. Steam in the air can be assimilated to a wetting agent, hence a surfactant, and can be used in an environmental-friendly way to ease the drying stage. Indeed, the challenge is to limit the risk of cracking and damaging pieces during this crucial step in material processing.

On the Distribution of Laplacian Eigenvalues of a Graph

引用

Acta Mathematica Sinica,English Series 2011年第11期27卷 2259-2268页

作者： Ji Ming GUO Xiao Li WU Jiong Ming ZHANG Kun Fu FANG Department of Applied Mathematics China University of Petroleum Dongying 257061 P. R. China Faculty of Science Huzhou Teachers College Huzhou 313000 P. R. China

This paper presents some bounds on the number of Laplacian eigenvalues contained in various subintervals of [0, n] by using the matching number and edge covering number for G, and asserts that for a connected graph the Laplacian eigenvalue 1 appears with certain multiplicity. Furthermore, as an application of our result （Theorem 13）, Grone and Merris＇ conjecture [The Laplacian spectrum of graph II. SIAM J. Discrete Math., 7, 221-229 （1994）] is partially proved.

新石器时代，装饰品的使用开始普及，考古发现的仰韶文化装饰品十分丰富，坠饰作为其中一种，在所有出土的仰韶文化装饰品中数量较大。仰韶文化的坠饰多以石、陶、玉、绿松石、角、牙、蚌为材料，经切割、刮削、雕琢、钻孔、精磨及火烧... 详细信息

新石器时代，装饰品的使用开始普及，考古发现的仰韶文化装饰品十分丰富，坠饰作为其中一种，在所有出土的仰韶文化装饰品中数量较大。仰韶文化的坠饰多以石、陶、玉、绿松石、角、牙、蚌为材料，经切割、刮削、雕琢、钻孔、精磨及火烧制成。其中有的可单件直接戴挂，有的与珠、管等组合成各种串饰使用。装饰的人体部位从前额、耳、颈、胸，一直到腰，有些还作为臂饰。本文对仰韶文化遗址和墓葬出土的坠饰的发现及材质进行考古学考察，并尝试对其功能、制作工艺及渊源做初步探讨。
