    摘要： Provided are processes for producing an oxalate by coupling of CO in the presence of a nitrite, wherein two or more reaction zones in series are used, and at least a portion of the oxalate as reaction product is separated between the reaction zones, and/or the nitrite is fed stagewise. The processes described herein can effectively enhance the selectivity to the oxalate and the single-pass conversion of the feedstock.

    摘要： A radiation reducing apparatus for a wireless communication device includes a sensing module, a control module, and a radiation reducing module. The sensing module senses radiation intensity of the wireless communication device and generates a signal corresponding to the sensed radiation intensity. The control module compares the sensed radiation with a preset radiation intensity threshold. The radiation reducing module is activated by the control module to reduce the radiation of the wireless communication device when the sensed radiation intensity reaches the radiation intensity threshold.
