Abstract: An apparatus is provided for improving the use of multiple-issue operations in a data processor. A variable-issue operation can be recognised is being either a single-issue operation or a multiple-issue operation in dependence on the state of the program at runtime. If a variable-issue operation can be scheduled as a multiple-issue operation, then other operations can be scheduled for performance in the same cycle, when they would have otherwise had to be scheduled for a later cycle. As such, more operations can be performed in fewer cycles thus improving code density and improving data processing performance.

Abstract: The present invention provides a method for synergistically vitrifying medium and low-level radioactive glass fibers and combustible solid nuclear waste incineration ashes. According to the chemical composition characteristics of incineration ashes of combustible solid wastes such as glass fibers, cotton, plastic, rubber and absorbent paper produced during the operation of nuclear facilities, the present invention takes the glass fibers as a glass matrix of combustible waste incineration ashes and minimizes the addition of an additive by a combination in different proportions through a synergistic treatment method. A vitrified form provided by the present invention meets the requirements of uniformity, density, impact resistance, chemical durability and the like of radioactive waste vitrified forms.

Abstract: The disclosure herein relates to a helical bed biofilm reactor for wastewater treatment, and belongs to the fields of environment engineering and chemical engineering. The helical bed biofilm reactor comprises a reaction vessel, a draft tube, helical screen meshes, carriers, a carrier passage, a gas distributor, a gas inlet, a gas outlet, a water inlet, a water outlet and a sludge outlet. By improving the arrangement structure of the carriers and the structure of the helical passage, the helical bed biofilm reactor improves the oxygen transfer rate, the oxygen transfer efficiency and the biological reaction efficiency of a biological treatment process of wastewater, and helps to control the thickness of the biofilm and reduce energy consumption in wastewater treatment.
