角蛋白是蛋白质的一种,广泛存在于人和动物的表皮和毛发以及动物的蹄、壳、爪、角等中,具有很大的回收利用价值。然而这些资源并没有得到广泛有效的利用,造成了资源的严重浪费。为了回收资源和保护环境,本文利用人发开发了一种新型的生物医学材料和质子导电膜。文中研究了人发的定量还原试验的工艺条件,包括还原剂溶液的浓度,还原反应的时间和温度。通过正交实验发现,当还原剂溶液巯基乙醇浓度为0.1mol/L,45℃下反

In this talk,we will propose a framework of risk measures for portfolio vectors,which is an extension of the ones introduced by Burgert and Rüschendorf (2006)
Consider an Ornstein-Uhlenbeck process,dXt = ??-θetaXtdt + σdBHt,driven by fractional Brownian motion BH with known Hurst parameter H ≥ 1/2 and known varianc
The talk is based on a joint work with Veronika Kurková and Michal Málek.We consider some properties of discrete dynamical systems such as the existenceof an
