吸力

• The idea is that the matter we see does not have enough gravitational pull to keep galaxies together
  这个学说指我们看见的物质没有足够的地心吸力是星系聚在一起。
• The stabilizers are akin to spidery legs with padded feet that grip the heart with vacuum suction
  这个稳定器就像是穿著防震脚垫的蜘蛛脚，透过真空吸力将心脏吸住。
• Alternately the test cock may be opened to break any suction caused by lifting internal assembly
  测试旋塞阀可能要交替开启，以阻断由于取出阀内件总成导致的任何吸力。
• At this moment , with a water coming , the sand floated and was drawn into a hole by a very strong power
  正在这时一股水流涌来，巨大的吸力使砂粒漂起来，被吸进了一个洞里。
• Field capacity the point at which the soil contains all the water it can hold by capillary and chemical attraction
  田间持水量：土壤通过毛细作用和化学吸力可维持的全部水量。
• If gravity were only slightly weaker stars couldn t form and the cosmos would be a thin undifferentiated blur
  若地心吸力稍稍减弱，星体无法成形，宇宙就成为模糊薄薄的一片。
• Features : lightly and ingeniously structured , easy for application , strong magnetic attraction power and safe in handling
  特点：结构轻巧、操作方便、吸力强大、不需外界能源。
• Three main problems caused by normal force when linear motor was used in machine tool were presented
  发现了法向吸力在直线电机的实际应用中导致的推力波动问题、装配问题和机床隔磁问题。
• Authorities say a grate at the bottom became dislodged creating a strong suction that pulled the teenage down
  有关部门认为是盆底的供热壁炉故障导致了强大的吸力的产生，将小孩拖到了盆底。
• We had to put lots of water pipe in and along the ground , but the system basically runs itself by gravity now
  我们有很多水沿着土地的管道而来，但现在这个方法基本上是让地心吸力本身来运作。
