X-ETFE (crosslinked ethylene-tetrafluoroethylene) insulating wire or cable with spiral stripe identifications for aerospace and preparation process for insulating wire or cable

The invention discloses an X-ETFE (crosslinked ethylene-tetrafluoroethylene) insulating wire or cable with spiral stripe identifications for aerospace and a preparation process for the insulating wire or cable. The preparation process for the insulating wire or cable includes steps of: printing spiral stripe identifications on an insulating layer of an X-ETFE insulating wire directly formed by a single insulating core wire; printing spiral stripe identifications on a sheath layer of an X-ETFE insulating cable formed by a single insulating core wire, a shielding layer and the sheath layer; printing spiral stripe identifications on an insulating layer and/or a sheath layer of an X-ETFE insulating cable formed by a plurality of insulating core wires, the shielding layer and the sheath layer; and printing spiral stripe identifications on an insulating layer and/or a sheath layer of an X-ETFE insulating cable formed by a plurality of insulating core wires and the sheath layer. The insulating core wires consist of conductors and the insulating layers which wrap the conductors. The X-ETFE insulating wire or cable with the spiral stripe identifications for aerospace is easy to be distinguished and identified, convenient to trace back and rapid in checking, and is beneficial to waste wire recovery. In addition, the X-ETFE insulating wire or cable with the spiral stripe identifications for aerospace has excellent high-temperature resistance, low-temperature resistance and radiation resistance, and the mechanical performance of the insulating layer is quite good.

Method for evaluating quality of oxide semiconductor thin film and laminated body having protective film on surface of oxide semiconductor thin film, and method for managing quality of oxide semiconductor thin film

Provided is a method for reliably and simply evaluating the quality of an oxide semiconductor thin film and a laminated body having a protective film on the surface of this oxide semiconductor thin film. Also provided is a method for reliably and simply managing the quality of an oxide semiconductor thin film. This method, which is for evaluating the quality of an oxide semiconductor thin film and a laminated body having a protective film on the surface of this oxide semiconductor thin film, has: a first step, wherein an oxide semiconductor thin film is formed on a substrate, after which the electron state of the oxide semiconductor thin film is measured by a contact method or a noncontact method, thereby evaluating defects arising from in-film defects in the oxide semiconductor thin film; and a second step, wherein the oxide semiconductor thin film is processed on the basis of a condition determined on the basis of that evaluation, after which a protective film is formed on the surface of the oxide semiconductor thin film, and then the electron state of the oxide semiconductor thin film is measured by a contact method or a noncontact method, thereby evaluating defects arising from defects at the interface between the oxide semiconductor thin film and the protective film.

Anchor rod length measuring method and anchor rod length measuring instrument

The invention discloses an anchor rod length measuring method and an anchor rod length measuring instrument. The anchor rod length measuring method comprises the following steps: a transmitting module is used for generating a plurality of sinusoidal signals with different frequency values according to a set frequency interval and transmitting the sinusoidal signals to an anchor rod in sequence; each sinusoidal signal is transmitted from the starting end of the anchor rod and is reversely transmitted to the starting end of the anchor rod after being reflected at the tail end of the anchor rod, so that incident waves and reflecting waves at the starting end of the anchor rod can be superposed to form standing wave signals; a receiving module is used for receiving the standing wave signals at the starting end of the anchor rod in sequence; a control module is used for mapping voltage values and frequency values of all the standing wave signals onto a two-dimensional curve; the length measurement of the anchor rod is realized through finding out a frequency value corresponding to a first wave trough point of the two-dimensional curve. The anchor rod length measuring method and the anchor rod length measuring instrument have the benefits that measuring signals are electromagnetic waves, so that non-destructive detection can be realized; the anchor rod length measuring instrument has he advantages of great coupling convenience, wide length measurement scope, high measurement accuracy and the like.

Integrally-formed explosion-proof membrane used on top cover of automobile lithium battery, and preparation method for explosion-proof membrane

The invention discloses an integrally-formed explosion-proof membrane used on a top cover of an automobile lithium battery, and a preparation method for the explosion-proof membrane. The explosion-proof membrane is characterized in that the overall explosion-proof membrane and the top cover of the lithium battery are manufactured and formed concurrently; the explosion-proof membrane is oval; an oval enclosure wall is arranged around the explosion-proof membrane; a protruding small enclosure wall is arranged on the lower surface, close to the lower surface of the inner edge, of the enclosure wall; a transitional small lug boss is arranged on the inner side of the enclosure wall; a pressing rib explosion-proof groove is formed in the oval part on the edge of the small lug boss; and trapezoid grooves are formed in the upper and lower surfaces, which are connected with the top cover of the lithium battery, outside the oval enclosure wall respectively. The explosion-proof membrane has the advantages that the explosion-proof membrane and the top cover of the lithium battery are manufactured and formed concurrently, so that a step of welding is omitted; and therefore, the safety problem of the product caused by melt-through of the explosion-proof membrane, or insecure welding and the like can be avoided consequently.
