Due to the complexity of investigating deformation mechanisms in helical rolling(HR) process with traditional analytical method, it is significant to develop a 3D finite element(FE) model of HR process. The key forming conditions of cold HR of bearing steel-balls were detailedly described. Then, by taking steel-ball r…
Acid-catalyzed heterogeneous oxidation with hydrogen peroxide(H2O2) has been suggested to be a potential pathway for secondary organic aerosol(SOA) formation from isoprene and its oxidation products. However, knowledge of the chemical mechanism and kinetics for this process is still incomplete. 3-Methyl-2-buten-1-ol(M…
Zr films have been successfully deposited on Mo substrate by pulsed laser deposition(PLD).The microstructure and morphology of the as-deposited films were examined by grazing-incidence X-ray diffraction(GIXRD), scanning electron microscopy(SEM) and atomic force microscopy(AFM). The results show that the dimension and…
牛顿图和，特别地一块分析平面向量地的低度的伪同类的术语允许我们决定典型轨道的存在和一个孤立的单个点的 separatrices。我们为在一个双性人维的微分系统的起源附近获得本地阶段肖像给一个容易的算法，我们提供几个例子。
