A synchronous control method and apparatus are disclosed for a web rotary printing press which comprises a first printing press, a second printing press, a drive motor for driving the second printing press, and a folder provided in the first printing press, and enables a web printed by the first printing press and a web printed by the second printing press to be superposed and folded by the folder. The synchronous control apparatus comprises a pattern phase deviation detecting sensor provided halfway through a transport path, on which the web printed by the second printing press is transferred so that the web is superposed on a web printed by the first printing press, and adapted to measure the position of a pattern printed by the second printing press, and a pattern phase deviation computing device and a central control device for controlling the rotation phase of the drive motor based on the position of the pattern printed by the second printing press, the position having been measured by the sensor.

A cross-linked fluorine-containing copolymer moldings applicable to a plasma irradiation step, which is molded as a peroxide cross-linking product of a fluorine-containing copolymer blend comprising a fluorine-containing elastomer copolymer and a fluorine-containing resin copolymer, which is a vinylidene fluoride-tetrafluoroethylene copolymer, both of the copolymers having reaction sites capable of reacting with a common peroxide-based cross-linking agent, respectively, has desired normal state physical properties and compression set value, even if applied to a plasma irradiation step, while reducing particle generation quantity of the fluorine-containing copolymers themselves.Crosslinked fluorocopolymer moldings which are obtained by subjecting a fluorocopolymer blend comprising both a fluoro- elastomer copolymer and a fluororesin copolymer consisting of a vinylidene fluoride / tetrafluoroethylene copolymer which each have reaction sites reactive with a common peroxide-type crosslinking agent to molding and crosslinking and which are subjectable to plasma irradiation. The moldings are reduced in the quantity of particles generated from the fluorocopolymer itself when subjected to plasma irradiation, and exhibit normal-state physical properties and compression set favorable to sealing material.

The invention discloses an online flaw detection process of a pipeline forming and machining process, which comprises the following steps of: additionally arranging a high-temperature resisting flaw detection head of a through vortex flaw detector and a counting device behind a discharging port of forming and machining equipment, and spacing a distance A between the high-temperature resisting flaw detection head and the counting device; additionally arranging a drive device and an alarm device in the through vortex flaw detector, connecting the control end of a detection device with the drivedevice and the alarm device, connecting the drive device with the counting device, and connecting the high-temperature flaw detection head and a length measuring device with the detection device; passing a pipeline from the discharging port through the high-temperature resisting flaw detection head first, carrying out online detection by the high-temperature resisting flaw detection head, once flaw points are founded, conveying detection signals of the flaw points to the detection device in time through the high-temperature resisting flaw detection head, processing the detection signals by the detection device, calculating a pipeline forwarding distance according to a distance signal transmitted from the length measuring device, when the distance is equal to the spaced distance A, drivingthe counting device by the drive device to carry out counting on the flaw points, giving an alarm in time and notifying operation personnel for processing.

The invention discloses a method for propagating sulzer braconid flies. The method comprises the following steps: firstly, culturing a host plant of tobaccos, then propagating sulzers and afterwards propagating the sulzer braconid flies by the sulzers. By propagating the flies in batches, the multi-generation repeated propagation of the sulzer braconid flies is avoided, the generation quantity ofthe hyperparasite flies of the sulzer braconid flies is reduced, and the survival capability of the sulzer braconid flies in the field is enhanced. The propagation time and quantity of the sulzer braconid flies can be flexibly regulated and controlled according to the actual condition of the field, and different requirements on the sulzer braconid flies under different situations are met. The emergence rate of the stiff aphids of the sulzer braconid flies propagated by the invention is more than 90%, the male-female ratio is 0.8-1.0:1, and the utilization rate of the stiff aphids or the adultflies is more than 80%.
