英文高手请改病句（5金币相送）（暂停，多谢！） Although the former species may be A and B , it was affirmed that the third one was the metallic state C. The origin of the former species is not clear. There are two possibilities. One explaination is that a small quantity of metallic C which was formed in the reduction process also can be reoxidized to A and B when expose to air, even though the samples collected under nitrogen protection. The other is that some A and B form after H2-TPR 中文意思 生成的前两种物质可能是Ａ和Ｂ，但第三种肯定是Ｃ。 前两种物质的生成可能有两种情况：一种是在还原过程中生成的金属C又重新被氧化成A和B，另一种就是在还原过程生成的。 可能有些乱，请您耐心的读完理解它。 我实在是找不到人帮我，这段话也是困扰我相当长的一段时间了，请大家帮忙。可能会耽误你很多宝贵的时间，不过请帮帮我。 如果您帮助我精心修改我愿送金币5个，50金币送完为止（本人金币不多，见笑，呵呵）。当然英语高人也不是冲着金币来的，一点心意。 [ Last edited by lydia-china on 2008-10-17 at 12:31 ] |

Although the former species may be A and B , it is affirmed that the third one was the metallic state C. The origin of the former species is not clear. There are two possibilities. One explaination is that a part of metallic C which was formed in the reduction process can also be reoxidized to A and B when exposed to air, even though the samples collected were under nitrogen protection. The other is that some A and B were formed after H2-TPR 又稍微改了几处呵呵不知如何加粗标记 你自己看看 而且化学外文文献要多用被动式这也是习惯吧...... |

Although the former species may be A and B , it was affirmed that the third one was the metallic state C. The origin of the former species is not clear. There are two possibilities. One explaination is that a small quantity of metallic C which was formed in the reduction process also can be reoxidized to A and B when expose to air, even though the samples collected under nitrogen protection. The other is that some A and B form after H2-TPR 中文意思 生成的前两种物质可能是Ａ和Ｂ，但第三种肯定是Ｃ。 前两种物质的生成可能有两种情况：一种是在还原过程中生成的金属C又重新被氧化成A和B，另一种就是在还原过程生成的。 主要问题： 1.时态。两种时态过去时和现在时混用，有些地方造成了混乱，如第一句，让步状语从句现在时，主句过去时，看不出道理何在。不如都改用现在时。 2.句法。形成“form”一词是用主动还是被动？楼主有些犹豫不决。另外还有其他一些小问题。 3.少数地方表意不清。 修改如下： Although the former species may be A and B , it is affirmed that the third one is the metallic state C. The origin of the former species is uncertain. There are two possible explanations. One is that a small quantity of metallic C which is formed in the reduction process also can be reoxidized to A and B when exposes to air, even though the samples are collected under nitrogen protection. Another possible explanation is that some A and B are formed after H2-TPR. [ Last edited by toreador on 2008-10-16 at 00:22 ] |
