The characterization of sulfonated polyetherketone (SPEK-C) films was investigated by using positron annihilation lifetime spectroscopy (PALS) and atomic force
Objective Chronic lead (Pb) exposure during development is known to produce learning deficits. Nitric oxide participates in the synaptic mechanisms involved in
It is well accepted that lower hybrid current drive (LHCD) is the most efficient method for non-inductive current drive in fusion devices and the effect of the

利用非线性σ-ω-ρ模型,在相对论平均场近似下,通过能量密度函数,给出了五夸克奇特重子态Θ+有效质量随核密度的增加逐渐下降的依赖关系,并进行了数值计算.分析了不同参数对
Methane conversion to C2 hydrocarbons has been investigated with the addition of hydrogen in a plasma reactor of abnormal glow discharge at atmospheric pressure
The concept of truth degrees of formulas in (L)ukasiewicz n-valued proposi tional logic Ln is proposed. A limit theorem is obtained, which says that the truth f
A new TiO2-modified film on carbon steel was prepared by electroless plating and sol-gel composite process. An artificial neural net was used to optimize the pr
Interdiffusion can be a major cause of failure in coated parts that see service at elevated tempera- tures. Ways to measure the extent of interdiffusion and mat
