培训 焊锡培训资料ppt免费下载焊接培训教程 ppt 下载特设培训下载班长管理培训下载培训时间表下载 时，至少要写两篇完整的英文 论文 政研论文下载论文大学下载论文大学下载关于长拳的论文浙大论文封面下载 ，让指导老师好好地修改，包括一些常用写作表达、格式等，这样比赛时才会比较从容；7.一定要按时按要求提交论文（电子档一份直发送至美国，交一份电子档，一份纸质档给学校负责老师，再统一邮寄），但千万别慌张，每个队伍仅限发送一次，注意发送时邮件主题的书写；8.电子档不需在前面加控制页，纸质档需在论文前加控制页；9.所有文件一律不允许出现名字，能显示你身份的只有页眉的队号，所以页眉要早早设好；10.美赛成绩只在网上统一公布，每个队伍一个网页（到时会给），获奖证书自己从网页上打印，没有发。11.美赛论文没有给出具体的写作要求，本论文模板仅供参考，写作时不必完全按照，有些模块可以根据具体问题进行改动。祝大家美赛好成绩！黄丹铃2014.12.23控制页（这是去年的，比赛时老师会给）
