在应对气候变化和实现“双碳”战略过程中,需要对温室气体进行高精度的观测,而目前在实验室关于量化不同观测系统精度差异的研究相对较少。本研究选择基于非色散红外吸收法的LICOR-830型CO_(2)气体分析仪与基于光腔衰荡光谱法的Picarro G2301型CO_(2)/CH4/H2O气体分析仪,对3种CO_(2)可溯源标气进行观测,开展重复性测试、漂移测试和目标标气测试,并对观测浓度进行精度对比分析。测试结果为1)重复性测试:LICOR-830的精度约为0.4 ppm,Picarro G2301的精度约为0.04 ppm,两者精度相差一个数量级;2)漂移测试:LICOR-830准确度为-4.22%,Picarro G2301准确度为0.82%,两者准确度相差5倍;3)目标标气测试:用3种浓度的标气对实测浓度进行1 h的校正后,LICOR-830精度提升15倍,达到0.026 ppm,准确度为-0.11%,Picarro G2301的精度略有提升,达到0.0341 ppm,准确度为0.03%。结果显示,LICOR-830的精度水平在校正后可满足WMO对CO_(2)观测的精度要求,具有较大的应用潜力。

准确评估城镇污水收集处理能力具有重要意义和价值。本研究以江苏某县域为研究区域,采用区域城镇生活水污染物(COD)的收集量作为核算对象,以集中式污水处理厂为核算单元,以260 mg/L和350 mg/L作为生活污水校核浓度,开展不同核算单元生活污水集中收集率的核算评估。结果表明,核算区域内生活污水集中收集率分别为67.09%(260 mg/L)和49.84%(350 mg/L),汛期生活污水集中收集率偏低。以新区为主的城东污水厂生活污水集中收集率高于均值,而以城镇老旧小区为主的城北污水厂和以城乡结合部为主的城南污水厂生活污水集中收集率相对较低。针对生活污水收集处理能力薄弱片区,提出治理措施,为城市生活污水集中收集效能提升提供参考。

Efficient viral vectors for mapping and manipulating long-projection neuronal circuits are crucial in structural and functional studies of the brain. The SAD strain rabies virus with the glycoprotein gene deleted pseudotyped with the N2 C glycoprotein(SAD-RV(DG)-N2 C(G)) shows strong neuro-tropism in cell culture, but its in vivo efficiency for retrograde gene transduction and neuro-tropism have not been systematically *** compared these features in different mouse brain regions for SAD-RV-N2 C(G) and two other widely-used retrograde tracers, SAD-RV(DG)-B19(G) and r AAV2-retro. We found that SAD-RV(DG)-N2 C(G) enhanced the infection efficiency of long-projecting neurons by^10 times but with very similar neuro-tropism, compared with SAD-RV(DG)-B19(G). On the other hand, SAD-RV(DG)-N2 C(G) had an infection efficiency comparable with r AAV2-retro, but a more restricted diffusion range, and broader tropism to different types and regions of longprojecting neuronal populations. These results demonstrate that SAD-RV(DG)-N2 C(G) can serve as an effective retrograde vector for studying neuronal circuits.
