| 1 | 镍钛形状记忆合金细胞相容性和生物力学兼容性的改进显示文摘镍钛记忆合金(NiTi)生物材料器件的发展,迫切要求研究和提高其细胞相容性和生物力学性能。依据美国材料测试标准协会(ASTM)的标准,我们研究表明:NiTi的细胞毒性比纯钛、Ti6A14V和316L不锈钢大,在NiTi表面作聚合四氟乙烯高离子(PPTFE)喷涂。可降低NiTi合金的细胞毒性,提高其抗腐蚀力。各种热处理方法可改善其疲劳性能,循环拉伸强度试验可测出其超弹性性能的衰减。 | L’H Yahia S.Lombardi N.Hagemeister G.Drouin C.H.

| 4 | An Internal State Variable Model for the Low Temperature Tempering of Low Alloy Steels显示文摘An internal state variable (ISV) framework is used to predict the rate and degree of strain relaxation associated with the stage I, low temperature tempering of martensite. A single variable tracks the change in volume between the tempered an untempered structures. The rate at which this occurs is taken to be a function of martensite fraction, temperature, degree of tempering, and carbon concentration. Experimental dilatometty data is used to both fit and validate the model. | Mark T. Lusk, Young-Kook Lee, Herng-Jeng Jou, William H.

| 5 | Modeling contaminant transport in homogeneous porous media with fractional advection-dispersion equation显示文摘The newly developed Fractional Advection-Dispersion Equation (FADE), which is FADE was extended and used in this paper for modelling adsorbing contaminant transport by adding an adsorbing term. A parameter estimation method and its corresponding FORTRAN based program named FADEMain were developed on the basis of Nonlinear Least Square Algorithm and the analytical solution for one-dimensional FADE under the conditions of step input and steady state flow. Data sets of adsorbing contaminants Cd and NH4+-N transport in short homogeneous soil columns and conservative solute NaCI transport in a long homogeneous soil column, respectively were used to estimate the transport parameters both by FADEMain and the advection-dispersion equation (ADE) based program CXTFIT2.1. Results indicated that the concentration simulated by FADE agreed well with the measured data. Compared to the ADE model, FADE can provide better simulation for the concentration in the initial lower concentration part and the late higher concentration part of the breakthrough curves for both adsorbing contaminants. The dispersion coefficients for ADE were from 0.13 to 7.06 cm2/min, while the dispersion coefficients for FADE ranged from 0.119 to 3.05 cm1.856/min for NaCI transport in the long homogeneous soil column. We found that the dispersion coefficient of FADE increased with the transport distance, and the relationship between them can be quantified with an exponential function. Less scale-dependent was also found for the dispersion coefficient of FADE with respect to ADE. | HUANG Guanhua, HUANG Quanzhong, ZHAN Hongbin , CHEN Jing, XIONG Yunwu & FENG Shaoyuan College of Hydraulic and Civil Engineering, China Agricultural University, Beijing 100083, China Chinese-Israeli International Center for Research and Training in Agriculture, Beijing 100083, China Department of Geology and Geophysics, Texas A& M University, TZ77843-3115, USA | 2005 | Science China Earth Sciences2005，48，z2： | 3 |
| 6 | Discrete large eddy simulation显示文摘Despite the intense effort expended towards obtaining a model for describing the turbulent flows of fluid, there is no model at hand that can do an adequate job. This leads us to look for a non-traditional approach to turbulence modeling. In this work we conjoin the notion of large eddy simulation with those of fuzzy sets and neural networks to describe a class of turbulent flows. In previous works we had discussed several issues concerning large eddy simulation such as filtering and averaging. Here, we discuss the use of fuzzy sets to improve the filtering procedure. | L.
