The existence of non-thermal wind gradients on the right side of the entrance region of the upper level jet (ULJ) and the left of the LLJ,leads to the unstable amplitude of mesoscale waves.

First, we make the Boussinesq approximation and study the effects of non-thermal wind and its spatial distribution on the superiority development of Mesoscale symmetric disturbance .

Ferrite MgFe2O4 coated carbonyl iron composite powder was prepared by heterogeneous nucleation combined with the liquid deposition method to improve the oxidation resistance performance of carbonyl iron powder.

Al_2O_3 nanosized composite powders encapsulated by ZrO_2(3Y) were prepared by heterogeneous nucleation combined with the co-deposition and were molded by dry pressing.

ZrO_2(3Y)encapsulated Al_2O_3 nano composite powders were prepared by heterogeneous nucleation combined with the liquid co-deposition method using pH buffer solution as precipitator.

The precursors of hydrate ferric oxide and basic nickel carbonate coated graphite microspheres were synthesized by the aqueous heterogeneous nucleation process using ferrous (Ⅱ) sulfate, nickel sulfate, sodium carbonate and graphite microspheres as main raw materials.

The precursor microspheres of Fe_2O_3·nH_2O coated with graphite were synthesized by the aqueous heterogeneous nucleation using ferrous(Ⅱ)sulfate,sodium carbonate and graphite microspheres as main raw materials.

Some features of the movement of internal particles within the concrete accompanied with settlement, segregation,and bleeding are analysed and investigated in this paper,and some methods for reducing the concrete shrinkage such as stipulating the concrete curing conditions,employing the skeleton effect of coarse aggregate,and creating nonhomogeneous phase coring are also investigated.
