The results show that BS 460MPa grade reinforced bar can be produced all from Q235 or 20MnSi billet by the remained heat treatment process but the production cost of the former is lower. When the water pressure minishes, the intensities of reinforced bar reduce; the higher the temperature at the entrance of cooling bed is, the lower the intensities are. Therefore, the commendatory process parameters are that five stages coolers should be opened, water pressure should be all 1.8～2.0MPa and the temperature at the entrance of cooling bed of Q235 reinforced bar should lower than 650℃. The typical microstructure(Q235): the surface layer is tempered sorbite; the transition layer is pearlite and ferrite, and the partial ferrite is acicular; the core is pearlite and ferrite and the grain fineness is 8～10 grade. The yield strength is reduced by 10～20MPa after natural ageing and it can be simulated by artificial ageing(100℃×2h or 200℃×1h).

结果表明，Q235和20MnSi钢都可以利用余热处理工艺生产出性能合格的钢筋，但前者的生产成本较低；水压减小，钢筋强度降低，上冷床温度越高，强度越低，推荐5段水冷器全开，水压均为1.8～2.0MPa，Q235钢筋的上冷床温度应控制在650℃以下；钢筋典型的金相组织（Q235）表层为回火索氏体，过渡层为珠光体+铁素体且部分铁素体呈针状，心部为珠光体+铁素体，晶粒度8～10级；自然时效后屈服强度下降10～20MPa，用人工时效可以模拟自然时效，工艺是100℃×2h或200℃×1h。

&镓在细菌寻找铁元素的过程中扮演'木马'病毒的角色，&Singh解释说，因为镓与铁元素很相似，被蒙蔽的入侵细菌误将镓做为铁摄入体内。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
