    • A method for improving the quality of ethylene glycol products, which mainly solves the technical problem of low UV-light transmittance of the ethylene glycol products present in the prior art. The method successfully solves the problem by use of the technical solution wherein the ethylene glycol raw material and hydrogen are passed through a rotating packed bed reactor loaded with solid oxide catalyst at a temperature of about 20 to about 280 ° C., a pressure of about 0.1 to about 4.0 MPa, a space velocity of about 0.2 to about 100.0 hr−1 and a molar ratio of hydrogen to ethylene glycol of from about 0.01 to 40:1, and ethylene glycol is obtained after the reaction. The solid oxide catalyst is at least one of copper-based, nickel-based and palladium-based catalysts, and the rotation rate of the rotating packed bed reactor is about 300 to about 5000 rpm.

    • Method and apparatus for improving the detection and discrimination of slow moving or stationary range-Doppler spread objects on or in close proximity to the ground (or sea surface). Invention detects, discriminates and separates radar returns from interference including ground clutter discretes via a coherent process for separating target returns from the myriad of received signals. Thus the method and apparatus improves the probability of detecting and declaring the presence or absence of an object at the same time that the probability of false declaration decreases. The method and apparatus may be applied to the processing of any over resolved object, including airborne radar.
    • 用于改善在或接近地面(或海面)上的慢移或稳定范围 - 多普勒扩散物体的检测和辨别的方法和装置。 本发明通过用于从无数接收信号分离目标返回的相干过程来检测,鉴别和分离雷达回波与包括地面杂波离散的干扰。 因此,该方法和装置提高了在虚假声明的概率降低的同时检测和声明对象的存在或不存在的概率。 该方法和装置可以应用于任何过度分辨的物体(包括机载雷达)的处理。
