Abstract: A micro-thrust and micro-impulse application device and method generates micro-thrust to a target by light pressure action from laser reflection. The device comprises a laser, a laser adjustment device, a beam splitter, a shutter, a reflector, and a laser power meter. Laser beam is generated by laser, adjusted by laser adjustment device, and divided into two paths by beam splitter. Laser in one path is measured at laser power meter; power measured determines magnitude for micro-thrust. In another path, it irradiates on the reflector on the target via shutter for generating micro-thrust. Light reflected by the reflector arrives at another laser power meter. Power of two laser paths are measured in real time by two laser power meters, acting micro-thrust is calculated by combining parameters including reflectivity and incident angle of laser irradiating the reflector, and light output power of the laser is adjusted in real time.

Abstract: The present invention relates to a pulverized coal fired boiler with wall-attachment secondary air and grid overfire air. Primary burners including primary air spouts, secondary air spouts and close coupled overfire air spouts arranged at intervals along the height direction of a hearth are arranged on four corners of the hearth. Two-way wall-attachment secondary air spouts and one-way wall-attachment secondary air spouts are arranged from bottom to top in a primary combustion zone where the primary burners are located. One-way wall-attachment secondary air spouts are arranged in a reduction zone between the primary burners and the top overfire air spouts, and grid overfire air spouts are arranged in a burnout zone where the overfire air is supplied.

Abstract: The present invention provides a method of preventing, alleviating and/or treating depression, comprising the step of administering to a subject in need thereof a therapeutically effective amount of a 7-alkoxy fangchinoline compound or a pharmaceutically acceptable derivative thereof.
