The growth mechanisms of YBa2Cu3O7-x films on MgO and substrates having the perovskite structure, SrTiO3 and LaAlO3, at deposition temperatures of 700-780 °C and (Ar+O2) pressure of ~70 Pa were found to be essentially different.
      
But the maximum attainable yield of singlet oxygen in Ar:O2 and He:O2 at fixed partial O2 pressure is found to be comparable with the O2(a1δg) yield in pure oxygen at the same pressure.
      
The yield is 62.1% when the oxidation is carried out under the reaction conditions of 60 °C, 2 MPa of O2 pressure, C5H5N as a solvent and molar ratio of the substrate to the complex of 1:10.
      
The iron-formation is suggested to be of submarine-exhalative origin, and precipitated in a moderately deep sea at low atmospheric O2 pressure.
      
The results suggest that the dehydrogenation of oleic acid to linoleic acid is preferentially inhibited at low O2 pressure.

This paper attempts to discuss the dynamics of bath movement in the oxygen bottom-blown converter. A parameter is suggested for selecting the oxygen pressure, called the nozzle delivery pressure ratio ε_α~'≤0.25. An equation is derived for quiet-blowing condition, which shows the relation to be obeyed, in order to prevent the injected oxygen flow changing from"gas-bubbling"to"gas-streaming". Another equation is given for good bath circulation, expressing the value of F_(?)~'to be kept. The formula derived for determining the converter volume defines the relation to be kept among hath diameter, oxygen flow, nozzle number, charge weight and converter volume, so as to prevent splashing.
