In this paper,the writer has analysed the basic operation of linear single linked list on establishment,search,insertion and deletion with graphs and algorithms,which can help the readers study more easily.

Based on the structural theory of Petri nets, the boundedness and liveness monotonicity of a subcategory of asymmetric choice (AC) nets, new extended strong asymmetric choice (NESAC) nets, were studied.

Ethoxylated nonylphenol phosphate gemini surfanctants with different degree of polymerization were synthesized by using ethoxylated nonylphenol,glycol diglycidyl ether and Phosphorus oxychloride as raw materials and BF3-ethyl ether as catalyst.

The Homopolymer of a cationic surface-active monomer,(2-acrylamido)ethyl tetradecyl dimethylammonium bromide(AMC14AB),was prepared through aqueous solution polymerization,and the homopolymer P(AMC14AB) was obtained.

Soapless latex with interpenetrating network structure (LIPN) is prepared by two-step polymerization with surface-active monomers; the influence of latex particle size and distribution, stor- age stability, water-resistance, use level of cross-linking agent and compatibility of the compositio ns on dynamic force property is discussed.

A novel cationic and acrylamide-type surface-active monomer,dimethyltetradecyl(2-acrylamidopropyl) ammoniumbromide(DTAB),was successfully synthesized,and cationic DTAB-co-acrylamide(AM) copolymer p(DTAB-co-AM)with hydrophobically associative property was prepared by free radical homogeneous copolymerization of DTAB and AM in aqueous solution,which had both ionic and hydrophobic groups.
