The invention discloses a wedge-shaped extrusion soft start device based on magnetorheological fluid and shape memory alloy. The wedge-shaped extrusion soft start device comprises a driving shaft and a driven shaft. A magnetorheological fluid transmission mechanism is arranged on the driving shaft. The magnetorheological fluid transmission mechanism comprises a driving inner cylinder, a driven outer cylinder and an excitation coil, wherein the driving inner cylinder sleeves the driving shaft and can rotate along the driving shaft, the driven outer cylinder sleeves the driving inner cylinder and can transmit the torque output by the driving inner cylinder to the driven shaft, the excitation coil can generate a magnetic field, a wedge-shaped work gap is formed between the driving inner cylinder and the driven outer cylinder, the wedge-shaped work gap is filled with magnetorheological fluid, and the magnetic field generated by the excitation coil can act on the magnetorheological fluid in the wedge-shaped work gap to enable the driving inner cylinder to drive the driven outer cylinder to rotate through the magnetorheological fluid. The wedge-shaped extrusion soft start device uses the extrusion reinforcing effect of the magnetorheological fluid to improve the transmission power. Meanwhile, the torque is transmitted through assistance of the memory alloy, so that the transmission performance of the soft start device is more reliable.

The invention relates to a power connection fitting for a high-voltage overhead transmission line, which comprises fixing frames, connecting frames and a connecting device, and the fixing frames are of annular structures, the connecting frames are uniformly mounted on the outer sides of the fixing frames, the connecting frames are of cylindrical hollow structures, and the connecting device is mounted between the outer sides of the connecting frames. The problems are solved that when an existing connection fitting is used, the connection effect is poor, use is inconvenient, the extension lengthof an adjusting rod cannot be effectively adjusted, then power transmission lines with different intervals cannot be used, the adaptation effect of the connection fitting is poor, and when the existing connection fitting is used, the connection fitting is poor in buffering effect and cannot effectively buffer vibration generated by a wire, so that a power transmission line is prone to generate alarge damping effect, and the conveying effect of the power transmission line is affected.

The method comprises the steps of determining an associated user set of a user and an advertisement attribute of an advertisement recognized by the user according to information of the user; and according to the advertisement attribute, carrying out advertisement putting on an associated user set of the user.

The present invention provides a vascular stent with anti-longitudinal deformation. The vascular stent includes several groups of annular supports and connecting ribs connected between every adjacent two groups of the annular supports; the vascular stent is nearly The adjacent annular supports at the end are connected by straight-line connecting ribs, and the middle and distal ends of the vascular stent are connected by S-shaped connecting ribs, taking into account the longitudinal strength and flexibility of the vascular stent in the longitudinal direction; at the same time, Increase the number of circumferential linear connecting ribs at the proximal end of the vascular stent, further enhance the longitudinal strength of the proximal end of the vascular stent, and ensure the overall flexibility and transportability of the vascular stent so that it can reach the vascular lesion smoothly Moreover, the width of the straight-line connecting ribs at the proximal end of the vascular stent is increased to further ensure that the proximal end of the vascular stent has sufficient longitudinal strength, and at the same time increases its contact area with the plaque, which can reduce the In-stent restenosis.

The invention provides a route updating method which reduces the flow rate of updating notifications, which are circulated in a network, to improve the scalability. A micromobility network includes routers connected in a tree connection and radio base stations connected to the routers in the lowest layer such that an updating notification of a route from a mobile terminal is repeated in order from a radio base station to successive higher order routers to update the route and a packet is distributed along the updated route. In the mobility network, directly lower order routers to each router are numbered to the numbers 1 to n with reference to the direct lower order router accommodation number n, and a route from the radio base station to the router in the highest layer represented by a route number composed of the numbers of the thus numbered routers is applied to the radio base station. Upon updating notification, the route number is referred to to determine a stage number m of a transmission range and the updating notification is transmitted to a higher order router corresponding to the stage number m.
