on the stability of copper species. These diagrams show the zone that limits the predominance of soluble species and the existence of insoluble Cu(II). Cu(II) exists mainly in the form of copper aquocomplexes... leads to widening of stability region of Cu(OH)1.5Cl0.5 and CuO, and makes the solubility of Cu(II) decrease. Fig.3(c) shows the predominance existence diagram of -lg m[NH3+NH4+] versus pH for 0.2......

Its combined string stability condition can be obtained through the method of the ring-road based string stability analysis. However, the partial string stability about traffic......
at the peak temperature of TMF cycling. The results show that the cyclic stress response of the material displayed an initial hardening regime followed by a saturation period and then cyclic softening till failure. The TMF cycling leads to the development of significant amounts of mean stress. Some life prediction models were employed to predict the TMF life of Z2CND18.12N, and the results......
