A comprehensive study of the effect of zinc oxide (ZnO) interlayer on the performance of bulkheterojunction organic solar cells (OSCs) ,based on poly[[4,8-bis[ (2-ethylhexyl) oxy] benzo [1,2-b:4,5-b] dithiophene-2,6-diyl] [3-fluoro-2-[ (2-ethylhexyl) carbonyl] thieno [3,4-b] thiophenediyl]] (PTB7) :3H-Cyclopropa[8,25] [5,6]fullerene-C70-D5h (6) -3-butanoicacid,3-phenyl-,methyl ester (PC70BM) blend system,is carried out by theoretical simulation and experimental optimization.It is found that a PTB7:PC70BM blend layer thickness optimized for maximum light absorption in OSCs does not generally give rise to the highest power conversion efficiency (PCE) .

设备管理是精益制造的基础支撑,设备管理精益化“四零”的追求就是用设备现有资源创造出更大的产出,实现高效发展;服务精益制造,提高对设备的把控力,在高效率、低成本的同时,有效保证产品质量,是设备管理的本质要求.从基础资料设备点检、设备维修、技术培训几方面就动力设备的精益化管理方面所作的部分工作作一些介绍.综合运用先进技术,将设备状态、管理过程、经济成本“三个可控”作为设备管理精益化的基本内涵,努力追求
以PFI磨为打浆设备,采用正交试验的方法,分别研究了打浆设备参数(打浆间隙、打浆时间)和浆料浓度对烟末和烟梗打浆功率、浆料质量(浆料叩解度、湿重)的影响.结果表明:①烟末和烟梗浆打浆过程中浆料浓度对打浆功率影响较大,打浆设备参数对浆料质量的影响较大;②随着打浆间隙上升,烟末和烟梗浆的叩解度都不同程度地下降,同时湿重也有相应的上升;烟末浆打浆功率受打浆时间变化的影响很小,而烟梗浆在打浆初期打浆功率偏
利用Zeta电位仪、PCD颗粒电荷测定仪、动态滤水仪、纤维形态分析仪等对再造烟叶浆料进行检测分析,结果表明:磨浆后浆料中的Zeta电位值为-14.6mV,加入瓜尔胶后变为-13.2mV,整饰盘磨浆的阳离子需求量为-93ueq/L,白水中的阳离子需求量为-270ueq/L,加入瓜尔胶后的上网浆阳离子需求量变为-207ueq/L,反而降低,但滤水留着实验及灰分测试表明瓜尔胶的加入会提高浆料的滤水性和留

运用六西格玛方法,对烘后叶丝水分合格率这一卷烟生产工艺中的重要指标进行了改进.首先对制丝生产过程进行流程分析,确定影响烘后叶丝水分的主要流程;进而确定影响因素,在对各因素进行检验基础上最终确定影响烘后叶丝水分的关键因素.最后,针对关键因素,进行实验设计,确定最佳方案,并纳入生产过程的控制范围.
本文对YJ17卷接机蜘蛛手处漩涡风机的运行情况进行分析,发现其运行过程中会将部分粉尘传送至风机叶轮处,进而导致漩涡风机负压不稳定,出现蜘蛛手夹烟不稳掉烟的情况,为此针对漩涡风机研制了对应的除尘装置,从根本上解决了漩涡风机叶轮积尘的问题,避免了蜘蛛手由于负压不稳掉烟的情况,并将清理漩涡风机的时间由原来的每月40分钟减少到3个月1次,甚至更短.

Recently,OLEDs based on triplet fusion delayed fluorescence have attracted much attention,because their IQEmax could reach 62.5%if triplet excitons could be converted efficiently into singlet ones thr
Thermally activated delayed fluorescence (TADF) based OLEDs have been attracting much attention recently because of its high external quantum efficiency (EQE) and little efficiency roll-off.
