Chemically modified ordered mesoporous carbon CMK-3 materials were prepared by means of an easy wet-oxidative method in 2 mol/L nitric acid aqueous solution. A
学前期是幼儿语言发展的最佳期。结合我园的实际情况，我们决定以语言活动为突破口，探索对幼儿语言创新能力的培养。我们把在全园各班开展以培养幼儿语言创新能力为目标的语言教
We proposed a new way to synthesize a nanocomposite consisted of cementite Fe3C nanoparticles and amorphous carbon by radio frequency plasma-enhanced chemical v
The reaction of a ruthenium carbide complex RuCl2(C:)(PCy3)2 with [H(Et2O)x]+[BF4]- at a molar ratio of 1:2 produced a two-core ruthenium carbene complex, {[RuC
局部放电检测是GIS设备绝缘状况诊断和评估的重要手段,进行绝缘状况评判除了要判断是否存在局放外,故障类型的确定也是非常重要的一方面.为了分析和判断不同故障(缺陷)激发的局放类型,文中模拟了四种常见的GIS故障类型,通过采用超高频(UHF)局放检测方法,提取了局放信号与相位、幅值及放电密度之间的关系,得到了典型的二维和三维放电图谱,该图谱可用于局放信号的故障类型诊断和识别.
A series of new compounds as highly potential acaricides was synthesized based on the structure of spiro-diclofen. Their structures were identified by 1H NMR sp
