The invention discloses a manufacture method of a reversible bonding micro-fluidic chip with high strength. The manufacture method includes using a sacrificial layer mold to manufacture and integrating a polydimethylsiloxane (PDMS) membrane of a micro pipeline structure firstly, aligning and attaching a structure face of the PDMS membrane to a pre-punched rigid substrate, then attaching the other rigid substrate with PDMS pre-polymer and curing agent mixed liquor coated in spin mode in advance to the back of the PDMS membrane, then solidifying to obtain a completely seamless attached substrate-PDMS-substrate sandwich type micro-fluidic chip, and finally, clamping two rigid substrates of the sandwich typemicro fluidicchip from the upper and lower faces by using a clamp, and therefore the ability of tolerating applied pressure intensity of the micro pipeline structure of the sandwich type micro-fluidic chip is enhanced. The sandwich type micro-fluidic chip of a combination clamp simultaneously has superiorities of assembling reversibly and resisting high pressure, broadens the applied range of the reversible bonding micro-fluidic chip greatly, and reduces application cost of the micro-fluidic chip.

The measuring instrument and the measuring method are suitable for detecting three-dimensional shapes of microspheres.
The invention discloses a parking brake relieving system of a railway vehicle. A parking braking check valve is arranged between a brake air cylinder and a parking brake control pulse valve; a normally open first cutout cock is arranged in the middle of an air path of an air suspension air cylinder towards a height valve and an air spring, and a pipeline leads out of the position between the air suspension air cylinder and the first cutout cock and is connected to the position between the parking brakecheck valve and the parking brake control pulse valve through a normally closed second cutout cock; after air pressure in the vehicle decreases to a certain value and parking brake is carried out automatically, a worker can introduce compressed air in the air suspension air cylinder into a brake by operating an on position and an off position of each cutout cock, and therefore parking brake of the brake is relieved. The parking brake relieving system of the railway vehicle can relieve parking brake of the vehicle by using the compressed air stored in the air suspension air cylinder on the vehicle when the vehicle has no power, relieve labor intensity of workers and bring convenience to operation and maintenance of the vehicle.
