condense(condensed matter physics)

condense concentrate 都是浓缩的意思 有什么区别

condense和concentrate的意思都比较多,就具体到“浓缩”这个概念,差别在于：

①

condense是通过“量”的减少而达到“浓缩”的目的.To reduce the volume or compass of.而在物理上也是To

cause (a gas or vapor) to change to a liquid.即“液化”或To remove water

from即“脱水”而达到密度增加的目的；

② concentrate则是To make (a solution or mixture) less dilute.即让溶剂或混合物减少稀释度.可以通过脱水（液体）提供浓度,也可添加物质提供浓度.

因

此总结,就定量而言,condense和concentrate都可以是通过分子/分母来计算；

condense是密度,concentrate是浓度；

condense通过减少溶液或相应容积而达到提高密度的目的（即减少分母）,而concentrate即可以是减少溶液,也可以是添加物质来达到提高浓

度的目的（即可是减少分母,也可以加大分子）.

compress，contract和condense的区别

compress，contract和condense的区别是：\x0d\x0acondense “凝结”、“浓缩”，“凝聚”，指密度增加，也可以表示文章，讲话内容“压缩”。 \x0d\x0acontract “收缩”，指由于物质自身内部因素致使整体收缩变小。其反义词是 expand。也可表示规模上的收缩。\x0d\x0acompress “压缩”，指用外界的压力使物体体积缩小，也可用于表示压缩内容、文字等。\x0d\x0a1、condense 例句：\x0d\x0a1）This can cause dew to condense out of the air, and mist to form in the air near the ground.\x0d\x0a这可能会导空气中水份凝结成露水, 在靠近地的空中形成雾。\x0d\x0a2）Under these conditions, large quantities of water evaporate and condense into clouds and rain — releasing heat in the process.\x0d\x0a在这种情况下,大量的水份蒸发，凝结成云和雨,并在此过程中释放热量。\x0d\x0a2、contract 例句：\x0d\x0a1）Muscles can expand or contract as we are doing exercises.\x0d\x0a我们运动时肌肉会伸胀或收缩。\x0d\x0a2）When it is frightened, a hedgehog will contract its body into a ball.\x0d\x0a刺猬受惊时, 身体会缩成一个球。\x0d\x0a3、compress 例句：\x0d\x0a1）They used a special pump to compress the inertia air into the container.\x0d\x0a他们使用一种特殊的泵压缩惯性空气进入容器。\x0d\x0a2）We hope to compress methane into a liquid fuel or pile it to homes for cooking.\x0d\x0a我们希望将甲烷压缩成液体燃料或将其用管道通家庭用于烹饪。
