波音737MAX飞机安装了全新设计的LEAP-1B发动机,采用复合材料风扇机匣、大宽弦比的高性能叶片,具有更好的燃油经济性和更低的二氧化碳排放量。发动机电子控制系统(EEC)增加了多项发动机气路油路控制功能,并集成了发动机反推控制功能,同时为减小EEC体积,将EECA/B通道和压力传感子系统(pss)分开设计,该设计在寒冷和冰雪天气容易造成pss结冰而导致故障。本文针对pss结冰产生的故障现象、故障原因进行了分析,并提供了预防方法。

3-Hydroxy-1-propanesulfonic acid(HPSA)was applied as a modification layer on poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate)(PEDOT:pss)film via spin-coating,resulting in a massive boost of the conductivity of PEDOT:pss film,and thus the as-formed PEDOT:pss/HPSA bilayer film was successfully used as a transparent electrode for ITO-free polymer solar cells(PSCs).Under the optimized concentration of HPSA(0.2 mol L^(-1)),the PEDOT:pss/HPSA bilayer film has a conductivity of 1020 S cm^(-1),which is improved by about 1400 times of the pristine PEDOT:pss film(0.7 S cm^(-1)).The sheet resistance of the PEDOT:pss/HPSA bilayer film was 98Ωsq^(-1),and its transparency in the visible range was over 80%.Both parameters are comparable to those of ITO,enabling its suitability as the transparent *** to atomic force microscopy(AFM),UV-Vis and Raman spectroscopic measurements,the conductivity enhancement was resulted from the removal of pss moiety by methanol solvent and HPSA-induced segregation of insulating pss chains along with the conformation transition of the conductive PEDOT chains within PEDOT:*** applying PEDOT:pss/HPSA bilayer film as the transparent electrode substituting ITO,the ITO-free polymer solar cells(PSCs)based on poly[N-9″-hepta-decanyl-2,7-carbazole-alt-5,5-(4′,7′-di-2-thienyl-2′,1′,3′-benzothiadiazole)]:[6,6]-phenyl C71-butyric acid methyl ester(PC_(71)BM)(PCDTBT:PC_(71)BM)active layer exhibited a power conversion efficiency(PCE)of 5.52%,which is comparable to that of the traditional ITO-based devices.

A single machine-infinite-bus(SMIB) system including the interline power flow controllers(IPFCs) and the power system stabilizer(pss) controller is addressed. The linearized system model is considered for investigating the interactions among IPFC and pss controllers. To improve the stability of whole system again different disturbances, a lead-lag controller is considered to produce supplementary signal. The proposed supplementary controller is implemented to improve the damping of the power system low frequency oscillations(LFOs). Imperialist optimization algorithm(ICA) and shuffled frog leaping algorithm(SFLA) are implemented to search for optimal supplementary controllers and pss parameters. Moreover, singular value decomposition(SVD) method is utilized to select the most effective damping control signal of IPFC lead-lag controllers. To evaluate the system performance, different operating conditions are considered. Reponses of system in five modes including uncoordinated and coordinated modes of IPFC and pss using ICA and SFLA are studied and compared. Considering the results, response of system without controller shows the highest overshoot and the longest settling time for rotor angel at the different operating conditions. In this mode of system, rotor speed has the highest overshoot. Rotor angel in the system with only pss includes lower overshoot and oscillation than system without controller. When pss is only implemented, rotor speed deviation has the longest settling time. Rotor speed deviation in the uncoordinated mode of IPFC and pss shows lower overshoot than system with only pss and without controller. It is noticeable that in this mode, rotor angel has higher overshoot than system with only pss. The superiority of the suggested ICA-based coordinated controllers is obvious compared with SFLA-based coordinated controllers and other system modes. Responses of coordinated pss and IPFC SFLA-based supplementary controllers include higher peak amplitude and l

We demonstrate the hydrothermal synthesis of long copper nanowires based on a simple protocol. We show that the purification of the nanowires is very important and can be achieved easily by wet treatment with glacial acetic acid. Fabrication of random networks of purified copper nanowires leads to flexible transparent electrodes with excellent optoelectronic performances (e.g., 55 Ω/sq. at 94% transparency). The process is carried out at room temperature and no post-treatment is necessary. Hybrid materials with the conductive polymer PEDOT:pss show similar properties (e.g., 46 Ω/sq. at 93% transparency), with improved mechanical properties. Both electrodes were integrated in capacitive touch sensors.

Selection of better optimized unified power flow controller （UPFC） control inputs along with simultaneous coordinated design of power system stabilizer （pss） is a challenge in the present scenario of power systems. Hence, in this paper, four sets of experiments performed are presented. First set of experiments are without disturbance scenario where switching is done using linear quadratic regulators （LQR＇s）. Second set is for power systems with disturbances using linear quadratic gaussian （LQG）. Switching control algorithms presented here are tested on the single machine infinite bus （SMIB） linearised Phillips Heffron model of power system using MATLAB/SIMULINK~ platform.

As a hole transport layer, PEDOT:pss usually limits the stability and efficiency of perovskite solar cells(PSCs) due to its hygroscopic nature and inability to block electrons. Here, a graphene-oxide(GO)-modified PEDOT:pss hole transport layer was fabricated by spin-coating a GO solution onto the PEDOT:pss surface. PSCs fabricated on a GO-modified PEDOT:pss layer exhibited a power conversion efficiency(PCE) of 15.34%, which is higher than 11.90% of PSCs with the PEDOT:pss ***, the stability of the PSCs was significantly improved, with the PCE remaining at 83.5% of the initial PCE values after aging for 39 days in air. The hygroscopic pss material at the PEDOT:pss surface was partlyremoved during spin-coating with the GO solution, which improves the moisture resistance and decreases the contact barrier between the hole transport layer and perovskite layer. The scattered distribution of the GO at the PEDOT:pss surface exhibits superior wettability, which helps to form a high-quality perovskite layer with better crystallinity and fewer pin holes. Furthermore, the hole extraction selectivity of the GO further inhibits the carrier recombination at the interface between the perovskite and PEDOT:pss layers. Therefore, the cooperative interactions of these factors greatly improve the light absorption of the perovskite layer, the carrier transport and collection abilities of the PSCs, and especially the stability of the cells.
