<正> 在数字化经济领域,一场静悄悄的革命正在发生,它就是企业间电子商务(B2B e-commerce)。迄今为止,B2B的聚光灯主要照在一些声望卓著的大公司身上,如思科公司和戴尔公司,它们抛弃了传统的中间环节,直接面对商业客户。然而真正的B2B电子商务革命发生在这些企业之外的地方。舆论普遍认为,互联网会减少供应链的中间环节,使企业更多地实现直接交流和交易。然而,对于中介的死亡通知书下得过早,事实上,新经济的重要现象之一

Aerosol and trace gas measurements were made at Kejimkujik National Park, Nova Scotia, Canada, during the summer of 1996. A case study from July 7-8 provides evidence of nucleation and condensation of products related to the oxidation of different biogenic emissions. Particles from 5 nm to 50 nm in diameter evolved during the afternoon and early evening associated with variations in isoprene. Late in the evening the alpha- and beta-pinene mixing ratios and the aerosol particle volume increased. Soon after, there was a sharp increase in RO2H/H2O2 that persisted until about 0100 LT. The initial increases in the pinenes and aerosols were strong and influenced by changes in winds. After 2200 LT, and into the early morning, the winds were relatively steady, and the alpha- and beta-pinene mixing ratios continually decreased. The decay of alpha-pinene is explained through reaction with O-3. However, the addition of OH radicals from the reaction of terpenes with O-3 is necessary to explain the observed rate of decay of beta-pinene. During the same time, the aerosol volume increased with the decrease in alpha- and beta-pinene. The volume increase was distributed 40:60 between particles in a mode centered at 80-90 nm and particles > 150 nm. The fine particle mass concentrations of the measured inorganic ions (sulfate, nitrate, chloride, ammonium, sodium, acid calcium) and organic ions (oxalate, formate, acetate, pyruvate, propionate) account for 25-30% of the total aerosol volume during the period (2.7 mu m(3) cm(-3)) indicating that the aerosol volume increase was due to unidentified species. Assuming that the increase in the aerosol was the result of products from the oxidation of alpha- and beta-pinene, an aerosol mass yield of 13% is estimated. The concentrations of cloud condensation nuclei active at 0.2% supersaturation were enhanced by the appearance of the 80-90 nm mode pointing to at least some of these forest-generated particles as being able to serve as nuclei for cloud droplets at common atmospheric supersaturations.
