THIN FILM TRANSISTOR ARRAY SUBSTRATE, METHOD FOR MANUFACTURING SAME, DISPLAY PANEL, AND DISPLAY DEVICE

A thin film transistor (TFT) array substrate, a method for manufacturing same, a display panel, and a display device. The method for manufacturing a TFT array substrate comprises: sequentially depositing a first metal oxide layer, a second metal oxide layer, and a source and drain metal layer, the electric conductivity of the first metal oxide layer being greater than the electric conductivity of the second metal oxide layer; and patterning the first metal oxide layer, the second metal oxide layer, and the source and drain metal layer, so as to respectively form an active layer (4-1), a buffer layer (4-2), a source electrode (5) and a drain electrode (6). The method can simplify the process of manufacturing a metal oxide TFT array substrate and reduce the production cost of the product.

Winter protection thermal isolation suit dress of inflatable

... 一种充气式的防寒保暖服装，包括衣服主体，衣服主体的内衬上设置数个气囊，相邻的气囊通过连通管连接，每个连通管上均设置阀门，至少一个气囊上设置气嘴，气嘴位于衣服主体的外侧。本实用新型使用时，利用工具通过充气孔给本服装充气，由于服装内充满气体使得人体与外界隔绝，从而达到御寒保暖的效果，另服装轻便，特别适用于寒冷天气中户外运动者；服装充气层的厚度可控制到最小，制作成小马甲穿于外套内，既保暖又不影响时尚；此外服装制作成本低，收纳方便，可谓物美价廉。各个气囊可以相互连通，通过对一个气囊充气便可以同时充气；当其中一个气囊漏气时，通过阀门关闭，避免影响其他气囊。 ...

Screening method of spore bacteria with low fermentation viscosity

The invention relates to a screening method of spore bacteria with low fermentation viscosity, which comprises the following steps: fermenting the spore bacteria to prepare fermentation liquor; centrifuging the fermentation liquor at a gradient rotating speed from low to high until the separated supernatant is clear, marking the rotating speed corresponding to the separated clear supernatant as nmax, and screening out a strain of which the nmax is lower than that of other strains from the spore bacteria as the spore bacteria with low fermentation viscosity; the fermentation conditions are as follows: a fermentation culture medium containing 0.1 wt%-0.5 wt% of diatomite is adopted, the fermentation temperature is 30-35 DEG C, and the fermentation time is 20-40 hours. Therefore, the evaluation of the viscosity of the spore bacteria is ingeniously realized, the operation is simple, and the high-throughput screening of the spore bacteria with low fermentation viscosity can be quickly realized ...
