Disclosed is a nitrile derivative compound represented by formula (I), a stereoisomer, a deuterated product, a co-crystal, a solvate or a pharmaceutically acceptable salt thereof, wherein each group is as defined in the description. The compound has dipeptidyl peptidase 1 inhibitory activity and can be used to prepare a drug for treating diseases including obstructive airway diseases, bronchiectasis, cystic fibrosis, asthma, emphysema, and chronic obstructive pulmonary diseases.

Nitrile derivative that acts as inhibitor of dipeptidyl peptidase 1 and use thereof

A vehicle running system based on rail transport, including a track, a framework, two levitation devices and a running device. The track is provided with a slot, in which the framework is provided. The levitation devices are provided between the track and the framework, and a top surface of the levitation device is fixedly connected to a bottom surface of the framework through a suspension structure. The running device includes two conductor plates and two running structures. The conductor plates are fixedly arranged on the inner wall of the slot, and are corresponding to the running structures. The reluctance force of magnetic wheels is converted into a driving force to drive maglev vehicles, and the levitation force is converted into a guiding force to realize the self-stabilization of vehicle guidance. A vehicle running method based on this system is also provided.

Vehicle running system and method based on rail transport

A magnetic wheel driving device and a driving method using the same. The magnetic wheel driving device includes a vehicle body, a guide rail system, at least two magnetic wheel systems and a power system. The guide rail system includes two conductor plates, respectively arranged at two sides of the vehicle body. The at least two magnetic wheel systems are symmetrically arranged at two side walls of the vehicle body. A gap is provided between each magnetic wheel system and the corresponding conductor plate. The power system is configured to drive the at least two magnetic wheel systems to rotate.
