Abstract: An integrated comprehensive adjustment method for a pulverized coal boiler based on high-temperature corrosion prevention and control of water wall is provided. The method includes: during shutdown period of the boiler, mounting reducing atmosphere sampling pipe on a water-cooled wall region; carrying out a diagnostic test on the boiler; carrying out an optimization and adjustment test of a boiler pulverizing system; carrying out a single-factor adjustment test of boiler-related parameters; determining degrees of influence of different parameters on water wall reducing atmosphere, thermal efficiency of the boiler and NOx concentration at a denitration inlet; carrying out an optimization test of ammonia spraying of a denitration system; carrying out a maximum safe denitration efficiency test; and finding a balance point among the water wall reducing atmosphere, the thermal efficiency of the boiler and the NOx concentration at the denitration inlet.

Abstract: Embodiments of present invention provide a linear-drive pluggable optics (LPO) transceiver. The LPO transceiver includes a receiver path, which includes a receiver optical subassembly (ROSA) converting an input optical signal into an ingress electrical signal; and a linear transimpedance amplifier (TIA) with adjustable frequency transfer function (AFTF), the ingress electrical signal passing through the linear TIA to a host. The LPO transceiver also includes a transmitter path, which includes a linear driver with AFTF receiving an egress electrical signal from the host; and a transmitter optical subassembly (TOSA) converting the egress electrical signal from the linear driver to an output optical signal. A method of operating the LPO transceiver is also included.

Abstract: A method and system for single-PDP dual-stack serial dialing is provided. A mobile terminal sets a single-PDP dual-stack serial dialing parameter according to a parameter setting command transmitted by a host; then the mobile terminal initiates a PDP activation request to a mobile communication network according to a first dialing instruction transmitted by the host and the configured single-PDP dual-stack serial dialing parameter, acquires activation response information fed back by the mobile communication network, generates dialing response information according to the activation response information, and feeds back the dialing response information to the host, wherein the dialing response information includes cause reference information. And after receiving the dialing response information, the host can acquire a specific condition of the current mobile network according to the cause reference information included in the dialing response information to determine a dialing mode.
