Abstract: An embodiment of the present invention discloses a repair system for a planetary exploration parachute. The repair system includes a folding piece and a fuse, the fuse is provided in the folding piece, a sensing signal for reflecting an impact force of dust is received by the fuse, fusing is generated in the fuse when the sensing signal is greater than a preset threshold, and the folding piece is changed from a folded state to an unfolded state after the fusing is generated in the fuse, so as to automatically repair a damaged part of the parachute.

Abstract: An embodiment of the present invention discloses a monitoring and repair method for a planetary exploration parachute system. The monitoring and repair method includes: sensing an impact force of dust and generating a sensing signal by a sensor; receiving the sensing signal by an electrode in a fuse; and when the sensing signal is greater than a preset threshold, fusing a safety wire in the fuse; after the safety wire is fused, changing a spring in the fuse from a compressed state to a natural state to generate tension; and rotating a repair rod under an action of the tension to drive a folding piece to be changed into an unfolded state from a folded state, thus realizing precise evaluation of impact damage of dust particles to a parachute body, closed-loop control and real-time self-repair.

Abstract: A measuring tape for measuring the size of limbs or waists is provided with a tape head capable of being stably inserted into a positioning hole during measurement and being automatically ejected out of the positioning hole after measurement, and includes a shell, and a cavity formed in the shell and used for receiving a flexible rule. An elastic switch assembly for clamping the tape head in the positioning hole is disposed at a position, close to the positioning hole, in the cavity. The elastic switch assembly and a leaf spring are disposed in the positioning hole, allowing the tape head to be inserted thereinto, in the shell, such that the tape head can be stably disposed in the positioning hole after being inserted into the positioning hole, and will not slide out of the positioning hole when users observe measure data.

Abstract: A method for detecting tumor tissue boundaries or a tumor stromal cell distribution range, more specifically, a diagnostic or non-diagnostic method for determining the boundaries of a tumor tissue; the boundaries of the tumor tissue are determined by means of determining the boundaries of the tumor stromal cells in the tumor tissue. The present method can more accurately determine the boundaries of tumor tissue, which serves to more accurately instruct the treatment of tumors, especially with respect to surgical treatment.

Abstract: The present invention relates to an oxo indirubin or isoindigo derivative, an oxo aza indirubin or isoindigo derivative, and their optical isomers, racemes, cis/trans isomers and pharmaceutically acceptable salts, which can be used for preparing a drug for treating or preventing diseases such as glucose metabolic disorder, inflammatory or autoimmune disease, neurodegenerative disease, a mental illness, tissue proliferation disease or tumors.
