当前电力营销业务已由单一的供电服务逐渐转变为碳交易、客户侧储能、多能供应、能效服务、分布式电源等综合能源服务,及时响应用户需求变得尤为重要。针对传统建设模式中存在的跨环节协作壁垒、业务需求响应不及时等问题,文章借鉴中台架构设计理念,首先提出一种公共共享服务研运一体化支撑平台(middle-platform service components,MSC),利用模型编排、服务编排、流程编排、界面编排进行微服务灵活实现及扩展;然后,结合架构资产统一管理以及MSC四编排引擎,基于多租户技术进行电力营销业务系统研运一体化建设;最后,通过在客户侧工单中心建设中的应用,证明该模式可为电力营销业务系统建设提供有效支撑。

Aluminum-doped zinc oxide （ZnO：AI） films were deposited by direct current magnetron sputtering in incorporating hydrogen in sputtering gas at room temper- ature. The influences of hydrogen content in sputtering gas on the structural, optical, and electrical properties of ZnO：A1 films were systematically investigated. It is found that hydrogen incorporated into ZnO lattice forms shallow donors in ZnO：A1 films and plays an important role in the properties of ZnO：A1 films. The electrical conductivity and infrared （IR） reflectance are improved due to the increase of electron carrier concentration, and the average trans- mittance decreases, which is ascribed to the strong scat- tering from the hydrogen incorporated and oxygen vacancies in ZnO：A1 films. In this study, the resistivity of 5.5 × 10-4 Ω.cm is obtained, the average transmittance of the wavelength in the range of 400-900 nm is almost 86 %, and the IR reflectance reaches 75 % at 2,500 nm, which is higher than that of reported TCO films. The band gap determined by optical absorption is a result of com- petition between Burstein-Moss effect and many-body perturbation effect. However, the hydrogen content in sputtering gas is above 10 %, and the optical band gap shift is independent of hydrogen content in sputtering gas.

In this article, polyphosphate-accumulating organisms （PAOs） from a lab-scale continuous-flow two-sludge system was isolated and identified, the different phosphorus accumulation characteristics of the isolates under anoxic and aerobic conditions were investigated. Two kinds of PAOs were both found in the anoxic zones of the two-sludge system, one of them utilized only oxygen as electron aeceptor, and the other one utilized either nitrate or oxygen as electron aeceptor. Of the total eight isolates, five isolates were capable of utilizing both nitrate and oxygen as electron acceptors to uptake phosphorus to some extent. And three of the five isolates showed good phosphorus accumulative capacities both under anoxic or aerobic conditions, two identified as Alcaligenes and one identified as Pseudomonas. Streptococcus was observed weak anoxic phosphorus accumulation because of its weak denitrification capacity, but it showed good phosphorus accumulation capacity under aerobic conditions. One isolates identified as Enterobacteriaceae was proved to be a special species of PAOs, which could only uptake small amounts of phosphorus under anoxic conditions, although its denitrification capacity and aerobic phosphorus accumulation capacity were excellent.

Drought stress is a major abiotic stress of common bean（Phaseolus vulgaris L.） throughout the world. Increasing the proline accumulation contributes to enhance crop drought tolerance. A c DNA for δ-o rnithine aminotransferase（δ-OAT）, an enzyme involved in the biosynthesis of proline, was isolated from Phaseolus vulgaris（Pv OAT）. Pv OAT exhibits 87.4 and 39.8% similarity of the deduced amino acid sequences with δ-OAT from Glycine max and Vigna aconitifolia, respectively. The transcriptional analysis revealed that Pv OAT was strongly induced by drought stress. And the expression of Pv OAT was higher in leaves than that in the root and stem of common bean by drought stress. Similar increase of the proline accumulation was observed in leaves and roots of common bean by drought stress. Furthermore, the proline content, the Pv OAT expression and the Pv OAT enzyme activity in cul tivar F5575 was significantly（P〈0.01） higher than that in cultivar F4851 under drought-stress conditions. Interestingly, it had been observed that, in the later stage of drought stress, the proline steadily maintained at the maximum level maybe result from the Pv OAT enzyme activity increasing steadily. These r esults indicated that the expression of Pv OAT and the accumulation of proline induced by drought stress treatment were related to the degree of common bean drought tolerance. So our results support the view that δ-OAT is associated with proline synthesis under drought stress conditions.
