The optimum technological parameters of pot-stewed chicken legs with higher product percentage were obtained by orthogonal design.

The results showed that the total yield could increased evidently with the outlet temperature of vaccum furnace increasing,and there was room for the outlet temperature raising.

Therefore the yield in the vacuum still raises 2.

The total yield of the VGO is in the range of 65%～76%.

Therefore the methane recovery rate can be improved.

In order to effectively use resources to enhance mine recovery rate,the paper studied down-dip strip mining method under the village,different plans were compared based on the actual situation.

Milling Quality and Inheritance of Kernel Hardness and Flour Yield of Common Wheat (Tricium aestivum L.);

It can expedite flour maturity, improve the colour and luster of flour, restrain flour going moldy and advance the flour yield.

The influence of striking detacher on flour milling properties were studied by determining the milling material granularity distribution,by flour yield determination and dough rheological test before and after using striking detacher.

"Jnder the proper conditions, the leaching efficiency of zinc could reach above 96%.

To improve the leaching efficiency,the effect of adding anode mud obtained from zinc electrowinning on zinc leaching was investigated,of which the leaching conditions including dose of anode mud,temperature,H_2SO_4 concentration and reaction time were tested.

With the technique of amalgamating ore tailing pelletized to heap leaching,there arrives a low leaching efficiency of no more than 54.
