对分批和半连续模式下柱式和平板式光生物反应器中湛江等鞭金藻的生长和油脂积累特征进行了评估。分批培养时平板式反应器可获得更高生物质质量浓度(2.06 g/L)、生物质产率[228.89 mg/(L·d)]和油脂产率[83.34 mg/(L·d)],且操作简单,易于放大,适于工业化培养。平板式反应器半连续培养虽然稳定期生物质质量浓度低于批次培养,但可获得更高生物质产率[342.83 mg/(L·d)]。气相分析结果表明,湛江等鞭金藻含有大量多不饱和脂肪酸。结果表明,平板式反应器中批次培养有利于湛江等鞭金藻油脂积累,半连续培养有利于生物质积累,可为工业化生产提供借鉴。

With the help of a set of exact closed-form solutions to the stationary Gross–Pitaevskii （GP） equation, we calculate the collective excitation and quantum depletion of a weakly interacting Bose gas in the presence of a periodic array of quantum wells. The excitation spectrum （Bogoliubov spectrum） is obtained from the solution of the linearized time-dependent GP equation, which develops energy bands hωj（ p） periodic in quasi-momentum space. Moreover, we calculate the excitation strengths Zj（ p） relative to the density operator and then the dynamic structure factor S（ p,ω）. Accordingly, the analytical expressions of quantum depletion of the system are obtained. We find that the quantum depletion is enhanced when the interatomic interactions become larger and the potential is sufficiently deep. The conditions for the possible experimental realization of our scenario are also proposed.

开征碳税对我国应对欧盟碳关税、促进产业绿色转型具有重要意义。论文基于投入产出法计算隐含碳排放强度,采用GTAP模型研究欧盟碳关税对我国的经贸冲击和我国开征碳税应对欧盟碳关税的实施效果。结果表明:我国不开征国内碳税时,随着欧盟碳关税税率的提高和征税范围的扩大,对我国经济贸易的冲击更大,有利于我国行业低碳转型;我国开征碳税后,从经济角度看,短期内碳税税率为10美元/吨和征税范围为CBAM覆盖范围内的行业时,对我国经济贸易的负面冲击较小。从低碳转型角度看,碳税税率为30美元/吨和仅对CBAM覆盖范围内的行业征税时,更加有利于我国高碳行业低碳转型。从整体角度看,我国对CBAM覆盖范围内的行业征收10美元/吨的碳税,更加有利于应对欧盟碳关税的威胁。
