A flexible transparent conductive film (TCF) is an important component in many modern smart devices. Recent TCF is always fabricated based on indium tin oxide (ITO). However, the drawbacks of ITO (e.g., brittle nature, high cost, and resource scarcity) and the complex preparation process of TCF limit the massive production and further application of TCF. Herein, a facile and low-cost method is proposed to prepare flexible TCF. Rolls of single-walled carbon nanotubes (SWCNTs)/polyvinyl butyral (PVB) interlayer film were first fabricated by the roll-to-roll (R2R) spraying method. Then, the interlayer film was laminated between polycarbonate (PC) films (0.1 mm in thickness) to fabricate a transparent (80% optical transmittance) but flexible trilayer film. Such a prepared trilayer film shows multifunctional applications. For example, on the one hand, high conductivity and uniform distribution of resistance ensure that it can work as a deicing window with good performance at a low voltage. On the other hand, its flexibility, rapid self-recovery, and stable response enable it to be used as a bending sensor, which shows remarkable stability, repeatability, and durability. This study provides a facile method to fabricate TCF based on commercial but low-cost materials, which is suitable for industrial production and wide practical applications.

The requirements for the display quality of the client's screen are becoming stricter and newer problems have been discovered. Our company has discovered a new type of streak defects: when blinking or shaking your head, you will find vertical stripes on the display, but you can't see the defects when staring at the screen. This shaking head pattern is found in many products. In this study, we selected the G127 screen and adjusted the Vcom of the 6.47‐inch A‐si screen to different degrees to reproduce the bad head‐shaking pattern. Observing the visual effects of the experimental screen, we found that the greater the deviation of the Vcom, the more serious the head‐shaking phenomenon. The brightness test of the screen with the shaking head pattern shows that as the degree of the shaking head pattern becomes heavier, the brightness difference between adjacent columns is larger. It can be seen that the minimum brightness difference of the shaking head pattern is 0.108nit.

The structural problem of materials, belonging to the field of material mechanics, is one of the most challenging problems for geotechnical materials. The theory of full state function for materials is a feasible method to describe the structural property of materials. Based on the analysis of structural parameters and its number in the geometric - mechanical material model, the concept of full state function for materials was introduced in this study. The full state function of structural parameters for the materials was obtained. It was found that, in the specific material analysis model, the number of the structural parameters of materials was known. The physical meaning of the corresponding material parameters was essentially the reflection of the degree of mutual influence among the directions of the structure of the material. The number of independent structural parameters represented the number of combinations which could produce influence independently among the direction of structured materials. The magnitude of the structural parameter reflected the degree of mutual influence among the structured directions. It could also be thought that the inconsistency of geometric - mechanical properties along the direction of the structured materials was reflected by the number of structural parameters, while the inconsistency degree was reflected by the magnitude of the structural parameters.

Preliminary petrographic observations and microthermometric measurements show that three types of fluid inclusions occur in quartz veins and late-stage carbonate veins in high- and ultrahigh-pressure (HP-UHP) rocks from the CCSD area (Donghai). Fluids include brine (NaCl-H2O) inclusions (type I), NaCl-CaCl2-H2O inclusions (type II), and N2-CH4 inclusions (type III). Type I fluids are divided into medium-high salinity (type Ia), medium salinity (type Ib), and low salinity (type Ic) inclusions. The type III inclusions are the first discovered in the CCSD area. Type Ia, Ib, and II inclusions are primary or pseudosecondary in origin and occur in vein- and matrix quartz in eclogites. Their absence in vein- and matrix quartz and in the amphibolite-facies gneisses suggests that Ia, Ib, and II inclusions were probably captured during decompression-recrystallization and retrograde metamorphism of the eclogite. In contrast, type Ic inclusions are widely distributed, and were probably captured in the last stage of UHP exhumation. N2-CH4 pure gaseous inclusions are mostly primary, and mainly occur as isolated or clustered inclusions in laminated quartz veins in eclogite together with types Ia and Ib inclusions; this implies that type III inclusions were probably captured under HP-UHP metamorphic conditions. Most quartz veins in eclogite probably formed by decompression-recrystallization and retrograde metamorphism during exhumation of the subducted plate, whereas quartz veins in the gneisses mainly formed at amphibolite-facies or late-stage retrograde metamorphism during exhumation. The distinct differences between fluid inclusions in quartz veins in eclogites versus those in gneisses, and the similarities among fluid inclusions in quartz veins and matrix quartz crystals in their respective hosting rocks suggests that metamorphic fluids expelled from the HP-UHP rocks during the exhumation migrated mainly at the grain scale.

The significant development of fabricated steel structure is helpful to solve the issue of excessive productivity in steel industry and promote the greenization, informatization and industrialization in construction industry. This paper takes a 220kV indoor substation for example to compare the stress ratio, displacement, types of joints and steel quantity of the steel pipe column frame with those of the mixed one. The result demonstrates that the employment of steel pipe columns for indoor substation structures can generate certain economic and social benefits.
