There are 12 phytoplasma diseases, including paulownia witches-broom,chinaberry witches-broom, cactus witches-broom, christmas cactus witches-broom, orange little leaf, petunia flat stem and so on were indentified using PCR with universal primers, which amplified phytoplasma 16SrRNA gene and/or ribosomal protein genes. So the kind of phytoplasma diseases in Yunnnan Province were understood. Identified the characteristic of 16SrRNA and rp gene of phytoplasma and the kind, classification and genitic relativity of these strains using RFLP, clonging and sequence analysis (nearly 20 full-length sequences of phytoplasma 16SrRNA and/or rp gene were submitted in GenBank ); The phytoplasma strains isolated from herbage plants were conserved in storeroom. 9 articles were published in the key journals of China and 1 technique invention patent was applied. The net-page about phytoplasma disease was established. 4 graduate student were bringed up.

Linear solvation energy relation was firstly introduced in the paper, and the method and step of gaining the special parameters of solvent and solute were introduced in detail, and these special parameters were used to selection and optimization of extractive agent in extractive distillation. The model of predicting activity coefficient at infinite dilution was established by linear solvation energy relation. By the above theory, several candidate solvents were selected to separate C5 fraction, and by experiment of vapor-liquid phase equilibrium at atmosphere pressure, the mixture of N-methyl-pyrrolidone including 4% water was used extractive agent of separating C5 fraction. Then binary vapor-liquid phase equilibrium of the some compound in C5 fraction and N-methyl-pyrolidone were determined at atmosphere pressure and correlated by NRTL equation. Isoprene being objective compound, experiments were operated in the laboratory-scale column; the processes were simulated by RadFrac model in ASPEN PLUS. And by the combination of experiment and simulation, the new process of separation of C5 was established.
