The invention discloses a low-temperature plasma induced membrane-type artificial lung graft modification method. The modification method includes the following steps that poly 4-methyl-1-amylene membrane materials for a membrane-type artificial lung are placed into a cavity of a plasma processing instrument, working gas is any one or two of pure ammonia gas, pure oxygen, pure argon and pure carbon dioxide, the pressure of the working gas is kept to be 20 Pa, the materials are processed for 1-5 min at the discharge power of 30-300 W, the gas flow is 30 ml / min-120 ml / min, phosphoryl choline compound steam is led into the cavity to induce vapor phase grafting, the steam pressure is stabilized to be 20 Pa, and the materials are processed for 1-5 min at the discharge power of 30-300 W. According to the method, the artificial lung membrane materials are modified through the low-temperature plasma technology, the process is simple, consumed time is short, the efficiency is high, the energy consumption is low, the biocompatibility of a poly 4-methyl-1-amylene (PMP) membrane is obviously improved, and the transmission performance of O2 and CO2 is slightly reduced compared with that before modification, however, the method still has wide medical application prospects.

The invention discloses a load transmission control method and device. The control method includes: receiving a trigger event reported by a proxy server, including a first transmission delay of a first member transmission path and a second transmission delay of a second member transmission path, and When one is greater than the first delay threshold, report the trigger event; initiate a request to the packet data network gateway and obtain its feedback network information; control the proxy server to execute the corresponding load according to the first and second transmission delays and network information distribute. Through the above scheme, the present invention can more accurately instruct the congested member transmission paths to implement a specific load distribution scheme, so that the WiFi network can be used to share the load of the 4G network under the premise of ensuring good communication quality, so that the load of each member transmission path The transmission cost is minimized, reducing the communication cost and greatly improving the user's service experience.

The invention discloses a heavy-duty overrunning clutch, which comprises an outer ring, an inner ring, a plurality of rollers and a retaining frame. The retaining frame comprises a support ring I, a support ring II and a plurality of support columns corresponding to the rollers. Spring plates are fixedly arranged on the support columns along the axial direction and are used for applying pre-tightening force on the rollers along the engagement direction of an engagement slot. The direct processing of a limit seat on the outer ring can be avoided, the working efficiency can be increased, the processing cost can be reduced, the service life can be prolonged, and the transmission effect can be guaranteed. Moreover, relevant components can be replaced easily after being damaged, the outer ringneeds not to be rejected as a whole, and the cost of maintenance and use can be reduced. The axial length of the overrunning clutch and the rollers can be increased theoretically indefinitely, the engagement length can be increased, and thus the bearing capacity of the overrunning clutch can be improved. Meanwhile, the pre-tightening force can be applied at multiple points of the rollers according to needs, and the limiting balance for the rollers can be guaranteed while the axial length is ensured, so that the rollers cannot deviate from the axial line of the inner ring. Therefore, the stable operation of the overrunning clutch can be ensured, and mechanical failure can be avoided.

The invention relates to a method for forming and preparing a carbon fiber drive shaft for a college students' formula car. Carbon fiber prepregs are used for winding a mandrel, after the mandrel is connected with connecting ends, winding is preformed continuously. The mandrel is removed by solidification after winding, spline ends are connected to form an integral shaft, a carbon fiber shaft bodyis formed by symmetrical angle layering in three stages, the metal connection ends are divided into flange edges and internal and external gluing parts, the spline ends are divided into flange edgesand spline parts, and the carbon fiber shaft body and the metal connection ends are in a double-lapped connection and mechanical connection mode, and the metal connection ends and the spline ends arefixed by bolts passing through the holes of the flange edges. The drive shaft can be used for various purposes by replacing the spline ends, has high durability and high fiber content, the connectionstrength between the metal connection end and the carbon fiber shaft body is high, the mass of the drive shaft is low, the rotational inertia is small and the natural frequency is high.

Provided is a system for transmitting broadcasting data. The broadcasting data transmission system may transmit broadcasting data using a plurality of transmit antennas and a plurality of receive antennas. A broadcasting data transmission apparatus included in the broadcasting data transmission system may differently determine a modulation scheme with respect to each of the transmit antennas, may differently determine a transmission power of each data stream based on the determined modulation scheme, and may differently determine a precoding vector.
