We select high barium ferrite as the active material of the battery cathode materials, and on the basis of the traditional high-speed rail barium preparation were added silicon sodium (Na 2 SiO 3 · 9H 2 O) and potassium permanganate (KMnO 4), as a synthetic additive to improve the stability of the battery and discharging performance.
The laboratory obtained high-purity potassium ferrate as starting materials, in the solution obtained with the barium salt (barium hydroxide or barium nitrate) Reaction Barium Ferrate precipitation, high iron of a high purity barium product obtained was purified by separation.

To the segment equipped with lifter, the materials contact with the gas fully, so the heat exchanges are more completely, and the gas temperature drops faster.
To the segment near to kiln end, the material sprayed into the kiln by nozzle contacts with gas fully, but the temperature difference between the gas and the materials is small, thus the gas temperature decreases more slowly.

Microwave-assisted extraction (MAE) has been widely applied for obtaining bioactive compounds from various food materials such as pulp, herbs, leaves, and peels [1-3].
In this study, extraction of anthocyanin content from Violet glutinous rice grown using fresh materials, extraction by MAE and RSM with a test design model process were performed to optimize the extraction processes.
Data in Table 2 shows that all linear components in the extraction process using microwaves were significant (p <0.05), in which microwave power had the strongest impact on extraction efficiency anthocyanin, followed by the ratio of raw materials/solvents and time.
Response surface plots of the natural anthocyanin content (Y) of the Violet glutinous rice seed a) materials-to-solvent ratio and microwave time; b) materials-to-solvent ratio and microwave power; c) Microwave time and microwave power 3.2.
