The invention discloses an array substrate, a liquid crystal display panel and a display device. The array substrate comprises a signal line, a wiring terminal gasket corresponding to the signal line and a peripheral routing line connected with the signal and the corresponding wiring terminal gasket. In the array substrate, since the peripheral routing line is composed of multiple leads which are arranged in different layers and in series connection, compared with an existing integral peripheral routing line, the peripheral routing line has the advantage that even if the wiring terminal gasket exposed to the air is corroded as moisture and oxygen in air are in contact, corrosion cannot extend inwardly to the signal line along the peripheral routing line so as to avoid the problem of abnormal display caused by the fact that the signal line is corroded. Besides, the peripheral routing line is arranged to be composed of the multiple leads arranged in different layers, compared with the integral peripheral routing line in the prior art, the peripheral routing line has the advantage that accumulation of static electricity on the peripheral routing line can be reduced since each lead is small in area.

A pump interface tubing for use in a peristaltic pump includes a tubular core having an outer surface and a treatment on the outer surface.

The invention discloses a method for preparing nickel hydrazine azide. The method comprises: taking soluble nickel salts as base solution; using acetic acid to adjust the pH of the formed base solution; using graphite as modified additives of medicaments; adding sodium nitride solution and hydrazine hydrate solution to the base solution dropwise to perform chemical combination; preserving heat, cooling, leaching, washing, dehydrating and drying; and obtaining a finished product of nickel hydrazine azide. The method is simple in pH control, and buffer solution consisting of weak acid and weak-acid salts ensures stable pH, longer effectiveness and the unicity of medicament composition, and significantly improves explosion initiation capacity, so the buffer solution is more suitable to be used as a primary explosive. By adopting nickel acetate as raw material, a small quantity of nickel hydrazine nitrate substances which are formed by use of nitrates and result in worse or unstable pharmaceutical performance can be avoided. Dropping and time difference ensure the complete reaction of sodium nitride and high yield of nickel hydrazine azide.
