The present thesis stated that the present commonly used "Arabic numerals" was not a result of just one invention,but a result of a historical process of gradual evolution.

A leather mildew preventive with nuclear-sheel structure was prepared by complex coacervation,where turpentine is the core material and the mixture of gelatin and gum acacia is the wall material.

In the presence of gum acacia, cadmium reacts with iodide and rhodamine 6G to form an ion--asso- ciation complex in 0.

The influence of hydrolysis time、temperature、acid concentration and solid to liquid ratio on xylose、arabinose and acetic acid concentration are assessed by single factor.

But in the process of ion exchange, xylose molecular is easily converted into arabinose because of catalytic isomerization, which results in the decrease of its purity and difficulty of crystal.
