There are four million seven hundred and thirty thousand hectare forests in Yunnan province at present, including one hundred and four million sixty three thousand mu Pinus Yunannensis and Pinus Kesiya, which accounts for 75.7 percent in whole province. There is five hundred million and two million stere storage of wood, accounts for 55.1 percent in total. It is also the first in China. If adequately use this resource, it will tap crude rosin one million two hundred and forty thousand ton, which can produce gum rosin eight hundred and ten thousand ton and gum turpentine oil three hundred and ten thousand ton.

Today afternoon go to do ShangZhan,arrive there at two O'clock,then time only two people, I think sure can ok soon ,but go to do it on four floor and go to one floor,ah,sudden have more people,I have to stand in a line,have a good many people pay money , more people do it .everyone over have sevel order ,really so annoy,why everyone come here on today? no easy turn to me,really indignant,my order have one item not see,and must rejigger,that is cruel,no way,none but stand in a line again,ah,waiting and waiting,until is ok at four O'clock.
今天下午去办商检,2点钟就去到了,那时只有两个人,心想肯定会很快办好,点知上去四楼做完单去到地上,呀,突然多了这么多人呀,我不得不排队,付钱又多人,出单就更多人了,人人都几份单以上,真是烦死人,都不知点解人人都今天来,好不容易轮到我了,真是激气,有一项电脑显示不出来,又要更改,真是惨呀,没办法啦,只有又排队了,唉,等呀等,等到4点几才办好。

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.

In the research on the backward-wave oscillation suppression the startoscillation current which is derived from Two-wave theory approximately is given up. Four typical un-uniform slow wave structures start-oscillation current equations are derived by backward-wave amplifing gain expressions with the Two-wave theory. Then the start-oscillation current rates I〓/I〓 between ununiform circuit and uniform circuit of the four structures have been got.
