摘要：以某电镀废水处理厂化镍废水处理工艺调试为基础,因排放标准的提高,针对原设计流程,通过实验室试验,确定最佳的运行工艺。实际的运行表明,工艺经过优化后,废水中总镍和总磷的去除率分别高达99.9%和99%以上,几乎可全部被去除,出水完全满足5电镀行业污染物排放标准6(GB 219000)2008)的要求。

摘要：大功率电力设备主要就是指需要专门设计以及专门性制作同时功率相对较大的设备类型。在交通领域、电力领域以及工业领域,大功率电力设备都发挥着至关重要的作用。随着电力设备功率不断增加,能源消耗也越来越大,如何实现大功率电力设备的节能成为了一个重要的课题。本文主要探讨了大功率电力设备的节能设计方法,包括设备结构优化、运行参数调整、余热回收利用等方面,并分析这些方法的可行性和有效性,以供相关专业人士进行参考和借鉴。

摘要：Rice(Oryza sativa)spikelets are a unique inflorescence structure and their development directly determines grain size and *** many genes related to spikelet development have been reported,the molecular mechanisms underlying this process have not been fully *** this study,we identified a new recessive rice mutant,lacking rudimentary glume 1(lrg1).The lrg1 spikelets only formed one rudimentary glume,which,along with the sterile lemmas,was homeotically transformed into lemma-like organs and acquired lemma *** transition from the spikelet to the floral meristem was delayed in the lrg1 mutant,resulting in the formation of an ectopic lemma-like organ between the sterile lemma and the terminal *** addition,we found that the abnormal lrg1 grain phenotype resulted from the alteration of cell numbers and the hull ***1 encodes a ZOS4-06-C2H2 zinc-finger protein with the typical EAR motifs,and is expressed in all organs and ***1 localizes to the nucleus and can interact with the TOPLESS-RELATED PROTEINs(TPRs)to repress the expressions of their downstream target *** together,our results reveal that LRG1 plays an important role in the regulation of spikelet organ identity and grain size.

摘要：与普通架线方式相比,装配式架线减少了弧垂观测、划印和压接工序,大大节省现场作业时间及被跨线路的停电时间,提高经济效益。该文介绍了采用装配式架线的线长计算方法、导地线制造要求、施工测量要求及施工工艺,给出了某500 k V线路装配式架线计算实例。

摘要：本文以乙醇－水为试验体系，研究了复合塔板在精馏操作时，影响泡沫层高度的诸因素，如孔动能因子、开孔率、孔径和表面张力等，提出了保证塔板上鼓泡的最小孔动能因子。同时还测定了泡沫层高度对板效率的影响，从而为复合塔板设计参数的选择提供依据。
