In a meeting held at Harbin 1959, discussing the possible over-winter sites of theOriental armyworm, Leucania separata Walker, in the Northeast, a hypothesis was pro-posed (Chang, 1959) that this insect most probably did not over-winter in the Northeast,but the outbreak every spring was due to mass migration of the adult moths along withthe south or southwest trade winds.
根据东北地区的粘虫极大可能不在本地越冬而是每年春季随南、西南风大量迁飞的假设,利用气象资料分析了东北早春粘虫成虫的发生与风向风速的关系。无论由始现期或突增期来看,与地面上或高空850 mb的南、西南风均有较高的符合率;在粘虫出现时期的南、西南风多为每秒5—6米到每秒9—10米的大风。

The sizes of the self-assembly micelles of the amphiphilic block copolymers and the effects werestudied by dynamic light scattering and UV-visible spectrophotometer. The micelle sizes werelargely influenced bythe hydrophobic chain content in the copolymer, the properties of the solvent and the copolymer concentration in the organic phase. The morphology of the micelles was investigated by transmission electron microscopy. Theresults showed that the micelles appeared spheres with inner core and outer shell. The critical association concentrations were determined by pyrene monomer fluorescence probe technology. The degradability of copolymer was studied by the loss of the intrinsic viscosity in the degradation process. The results indicated that the degradation rate of PECL was slower thanthat of PELLA and PEDLLA. The stability of the copolymer micelle dispersion was examined by measuring the critical flocculation concentration, which gradually decreased with increasing the content of thehydrophobic chain in the copolymer. The rheological results showed thatthe viscosity ofthe micelle dispersion with higher content of PEG segments was firstly decreased and then increased with the increasingthe temperature. Otherwise, the variation of viscosity was irregular. The viscosity of the micelle dispersion increased with the increase of the electrolyte (Na 2SO 4) concentrations. Polymer micelles paclitaxel was prepared by self-emulsification/solvent evaporation method and solid dispersion technique with amphiphilic block polymers as the carrier material.
