The metal content of Tieguanyin tea from Anxi, Southeast China, was studied. Leaching experiments were designed based on the local tea-drinking habits, and tea infusions were prepared using three types of water and two methods of soaking tea. Twelve metals (Cd, As, Cr, Pb, Se, Sb, Ag, Tl, Cu, Zn, Be, and Ba) were measured by inductively coupled plasma mass spectrometry (ICP-MS), and a human health...
The four main factors that influence the metal wear performance are determined. Wear Prediction model is developed based on partial least-squares regression method including the four parameters. The fuzzy and random characteristic of metal wear is analysed and the method of the prediction of fuzzy random reliability of metal wear is carried out according to the wear prediction model. The modal is...
