It is not in cosmic space which is empty of anything , but in the world which is full of such familiar things as grasses , flowers , birds , utility poles and signals 那里并不是真空的宇宙空间，而是一样是有花草、鸟、电线杆和信号等亲切事物的世界。
It firstly heats and softens the plastic sheet and covers it onto the shoetree , then uses vacuum suction method to profile to shape of the shoetree with the plastic foil 本机将塑料胶片加热软化后，覆盖在鞋楦上，利用抽真空的方法，将鞋楦的形状覆制。
But when theorists try to compute the energy density associated with the quantum vacuum , they come up with values that are at least 55 orders of magnitude too large 然而，当理论学家尝试计算这个量子真空的能量密度时，他们得到的结果比目前的观测值至少大55个数量级。
Secondly , it is consistent with the hope that the ultimate vacuum energy might actually be zero , and that we simply haven t relaxed all the way to the vacuum as yet 此外，把真空能量重新假设为零亦符合不少科学家的祈望，除非事非必要，我们仍不想放弃对真空的传统理解。
Siphon outlet piping can cut off the outlet flow safely and easily when the pump is stopped . it is of high value in application 虹吸式出水管在水泵机组停机时采用破坏真空的办法断流，操作简便可靠，能及时切断水流，安全有效，在城市排污泵站中具有较大的实用和推广价值。
