为研究温拌剂EC-120对SBS改性沥青流变性能的影响规律,通过布洛克菲尔德黏度计法、DSR和BBR试验分别研究了EC-120温拌剂在不同掺量(2%、4%、6%)下对SBS改性沥青高温黏度、高温抗车辙能力及低温抗裂性能的影响,并以车辙因子和蠕变劲度的老化指数为指标分析4%EC-120温拌剂对SBS改性沥青老化性能的影响。结果表明,EC-120温拌剂可以显著降低SBS改性沥青的高温黏度,提高SBS改性沥青的高温抗车辙能力,但会对SBS改性沥青的低温抗裂性能产生消极影响;EC-120温拌剂可改善SBS改性沥青的老化性能,减缓老化速率。建议EC-120温拌剂掺量为4%。

Cytoplasmic lipid droplet （LD） lipolysis is regulated by pheromone biosynthe- sis activating neuropeptide （PBAN） in Bombyx mori. To elucidate the molecular mechanism of cytoplasm LD lipolysis, the pancreatic lipase-like gene in B. mori pheromone glands （PGs）, designated as B. mori pancreatic lipase-like gene （BmPLLG）, was identified in this study. Spatial expression analysis revealed that BmPLLG is a ubiquitous gene present in all studied tissues, such as PGs, brain, epidermis, egg, midgut, flight muscle and fat body. Temporal expression analysis showed that the BmPLLG transcript begins to express 96 h before eclosion （-96 h）, continues to increase, peaks in newly emerged females and steadily decreases after eclosion. Translational expression analysis of BmPLLG using a prepared antiserum demonstrated that BmPLLG was expressed in an age-dependent pat- tern at different development stages in B. mori. This finding was similar to the transcript expression pattern. Further RNA interference-mediated knockdown of BmPLLG signifi- cantly inhibited bombykol production. Overall, these results demonstrated that BmPLLG is involved in PBAN-induced sex pheromone biosynthesis and release.

The near-infrared imaging channel constitutes a crucial component of the multichannel high-resolution imaging system of the New Vacuum Solar Telescope(NVST). We have successfully achieved high-resolution, narrowband imaging of the chromosphere using He I 10830 A triplet within this channel, which significantly enhances the imaging observation capabilities of NVST. This paper provides a concise overview of the optical system associated with the near-infrared imaging channel, detailing data processing procedures and presenting several observed images. Leveraging a high-resolution image reconstruction algorithm, we were able to generate a narrowband image near the diffraction limit at 10830 A with a temporal resolution of less than 10 s.

为了明确紫花苜蓿品质形成差异的水分生理特征,探索因地制宜、节水高效的灌溉模式,以河西地区为例,以不灌水(CK)为对照,对比分析了常规畦灌(M)、交替灌溉(T)和隔沟灌溉(G)等3种不同灌溉方式分别在灌底墒水、越冬水、返青水和现蕾水不同灌溉量下对“三得利”紫花苜蓿产量和品质的影响。结果表明:(1)不同灌水方式下株高与灌水次数呈正相关,分支数与灌水量呈负相关;交替灌溉在灌底墒水、越冬水、返青水和现蕾水条件下株高三茬平均值最高为91.92 cm。(2)各灌水模式下,紫花苜蓿净光合速率、蒸腾速率随灌水量的增大表现出增高的趋势,其中交替灌溉的净光合速率随灌水量的增大提高了15.64%,且均高于常规畦灌和隔沟灌溉在同等灌水量下净光合速率。(3)不同处理紫花苜蓿的产量随灌水量的增加而增加,漫灌处理紫花苜蓿的三茬总产量显著高于交替灌溉与隔沟灌溉在相同灌水量下苜蓿产量,在灌底墒水、越冬水、返青水和现蕾水条件下三茬总产最高达49447.6 kg/hm^(2)。(4)不同灌水方式紫花苜蓿粗蛋白含量和中性洗涤纤维含量显著高于无灌水(CK)处理,且随着灌水量的增加有不同程度的提高。河西地区地处干旱和半干旱区,以节水灌溉的角度出发,可以选择交替灌溉灌底墒水、越冬水、返青水和现蕾水的灌溉模式能够在保证高产的同时,达到节水的目的。
