咖啡粉

• Initial investigations indicate that the cocaine was smuggled into hong kong from south america and they were probably mixed with coffee powder to make it more difficult for detection
  警方调查显示，这批可卡因由南美偷运进港，相信贩毒集团曾将该批可卡因混和咖啡粉，藉以逃避执法人员侦查。
• Simpler and cheaper are solid - fuel engines ; their fiery impetus comes from burning premixed fuel and oxidizer grains that are packed like coffee grounds into a cylindrical casing
  固体燃料引擎比较简单，也比较便宜，其猛烈的推力来自于燃烧预先混合好的燃料和氧化剂颗粒，它们像磨好的咖啡粉一样，装在圆筒状的容器中。
