In th.s article we discuss Noeth.r conservation laws admitted by a Lagrangian L = gab(dx^a/ds)(dx^b/ds)of a test particle moving in th. field of a general plane symmetric non-static spacetime metric. In th.s context, we first present a general solution representing a Noeth.r symmetry vector subject to differential constraints satisfied by th. general plane symmetric non-static metric. We th.n use a class of plane symmetric non-static metrics obtained by Feroze et al. and discuss, in each.case, Noeth.r conservation laws in comparison with.Killing symmetries.

Th. use of waste crumb rubber powder as a modifier for modified asph.lt can recycle waste rubber to ease pressure on th. environment and improve th. performance of asph.lt. Diffusion of components of asph.lt into waste rubber is of vital importance to improve th. performance of rubber modified asph.lt,wh.le th. related research.s are scarce. Diffusion of components of asph.lt into waste rubber at different temperatures h.s been investigated in th.s work. Rectangle rubber was immersed in asph.lt at certain temperature for a period of time. And th. mass increment of rubber was measured to determine th. diffusion rate of components of asph.lt into rubber. Th. experimental results indicated th.t th. diffusion rate of components of asph.lt into waste rubber increases along th. temperature,but th. diffusion rate of components of fractions oil wh.ch.is distillated from catalytic cracking slurry is much.h.gh.r th.n th.t of components of asph.lt. Compared with.asph.lt,fractions oil enjoys lower viscosity and better permeability with.h.gh.r content of saturates and aromatics. All th. ch.racteristics are contributed to th. efficient diffusion of components of fractions into waste rubber.

Nanostructured Fe-doped titanium dioxide was synth.sized from titanium containing electric furnace molten slag （TCEFMS） by using an alkali fusion, followed by a h.drolyzation-acidolysis-cMcination route. Th. effects of Mkali/slag mass ratio, calcinating temperature, calcinating time, and water/slag mass ratio on th. extraction efficiency and purity of products were systematically studied in th.s paper. It is indicated th.t th. best extraction efficiency of nanostructured Fe- doped titanium dioxide is 99.35%, wh.n th. molten slag is calcinated at 700℃ for 1 h.with.th. mass ratio of alkali/molten slag of 1.5：1. Th. influence of alkali/slag mass ratio on th. ph.tocatalytic activity of final products was evaluated by th. ph.todegradation of meth.l blue under visible ligh. irradiation. A maximum ph.todegradation efficiency of 88.12% over 30 min was ach.eved under th. optimum conditions.
