    • It has been discovered that carbonate powders and bicarbonate powders are useful to increase the pH and corrosion resistance of high-density brines, such as zinc bromide brines, without significantly reducing their densities. The carbonates and/or bicarbonates should be water-soluble and may be sodium, potassium, magnesium and/or ammonium carbonates and/or bicarbonates and the like. The carbonates and/or bicarbonates are easily added in powder or other finely divided solid form and are completely dissolved in the brine prior to pumping the brine into a subterranean formation.
    • 已经发现,碳酸盐粉末和碳酸氢盐粉末可用于增加高密度盐水如溴化锌盐水的pH和耐腐蚀性,而不显着降低它们的密度。 碳酸酯和/或碳酸氢盐应该是水溶性的,并且可以是碳酸钠,钾,镁和/或碳酸铵和/或碳酸氢盐等。 碳酸盐和/或碳酸氢盐容易地以粉末或其他细分散的固体形式加入,并且在将盐水泵送到地下地层之前完全溶解在盐水中。

    • Methods and apparatus are provided for radar systems using multiple pulses that are shorter than the expected range delay extent of the target to be imaged. In one implementation, a method for performing radar includes the steps of: transmitting a plurality of pulses, each pulse having a different center frequency and a time duration shorter than an expected range delay extent of a target, wherein a total bandwidth is defined by a bandwidth occupied by the plurality of pulses; receiving reflections of the plurality of pulses; and performing pulse compression on the received pulse reflections to generate a detection signal having a radar resolution approximately equivalent to the transmission and reception of a single pulse having the total bandwidth. In preferred form, the pulses comprise ultrawideband (UWB) pulses each occupying a sub-band of the overall system bandwidth.
    • 为使用比要成像的目标的预期范围延迟范围短的多个脉冲的雷达系统提供方法和装置。 在一个实施方式中,执行雷达的方法包括以下步骤:发送多个脉冲,每个脉冲具有与目标的预期范围延迟范围不同的中心频率和持续时间,其中总带宽由 多个脉冲占用的带宽; 接收多个脉冲的反射; 并对所接收的脉冲反射进行脉冲压缩,以生成雷达分辨率近似等于具有总带宽的单个脉冲的发送和接收的检测信号。 在优选形式中,脉冲包括每个占据整个系统带宽的子带的超宽带(UWB)脉冲。
