Density Functional Theory method was used to optimize the geometries of 209 PCDE molecules, 209 PBDE molecules and 75 PCDD molecules at the B3LYP/6-31G* level. Using computed structural parameters as theoretical descriptors, the forward stepwise multiple regression technique was adopted to obtain QSPR models of environmental partition properties for these POPs by using GQSARF 2.0 and SPSS12.0 for windows programs. The obtained QSPR models are as follows:(1) QSPR models for predicting subcooled liquid vapor pressure, n-octanol/water partition coefficients lgK_(ow and subcooled liquid water solubilities -lgS_(w, l of PCDEs, of which correlative coefficients (R~2) are 0.988, 0.958 and 0.959 and the root-mean-square-error of estimation are 0.134, 0.116 and 0.327 respectively.(2) QSPR models of lgPL and n-octanol/air partition coefficients lgK_(oa for PBDEs, which both contain three structural parameters. The values of R2 for the two models are both 0.997 while the values of RMSEE are 0.073 and 0.062 respectively.(3) QSPR models of lgKow and–lgS_ for PCDEs, which both have one variable (mean molecular polarizability, α). The values of R~2 for the two models are 0.978 and 0.866 and the values of RMSEE are 0.300 and 0.270 respectively.(4) The molecular structures of 24 substituted naphthaline compounds were optimized using Hartree-Fock and DFT methods at four different levels and the same means was used to obtain four three-parameter (EHOMO, q~+ andα) QSPR models of lgK_. The model at the HF/6-311G** level is the best one of which R2 is 0.9662 and RMSEE is 0.380.(5) QSPR study for environmental partition properties of PCDEs was also performed using position of Cl substitution method in which simple parameters of substitution position were taken as descriptors. The multiple linear regression was performed with GQSARF 2.0 and SSPS 12.0 for windows programs to obtain QSPR models of lgP_L, lgK_ and–lgS_ for PCDEs of which R~2 are 0.991, 0.983 and 0.965 and RMSEE are 0.311, 0.100 and 0.300 respectively.

The root-cause for the synchronous error of multiple axes of the vehicle panoramic sight platform was found after analysis with the geometric method. Since the synchronous error is caused by the windage angle produced in the working process of the optoelectronic platform, the method to correct the angular deviation at any distance is proposed. The experiment for solving the problem was implemented. The experiment indicates that the method is valid.

Result The results showed that, for the induction effect of the adventitious buds from leaves, the combination of 6-BA and IBA was better than that of 6-BA and NAA. The best bud induction medium for Polestar yellow was MS + 6-BA 0.6 mg/L + IBA 0.04 mg/L, and the mean number of the normal induced buds was 8.3 per month. The best proliferation medium was MS + 6-BA 0.8 mg/L + NAA 0.04 mg/L, and the proliferation multiple of the normal buds was 7.4 per month. On 1/2 MS medium with IBA 0.25 mg/L, both the root regeneration rate and the mean root number of the plantlets were highest.
