注意事项: 1.竞赛时间限为6小时。实验竞赛最高分为40分。 2.实验操作中若遇到困难(如仪器的安装与使用)可询问监考人,以获得帮助。此类询问不扣分。 3.若合成实验失败,可作如下选择: (1)征得监考人同意后重做、不扣分。 (2)要求提供粗产品,扣5分。 (3)要求提供合成的最终产品,接下去做分析实验扣8分。
Notes: 1. The duration of the competition is limited to 6 hours. The highest experimental competition is divided into 40 points. 2. If you encounter difficulties in the experimental operation (such as the installation and use of the instrument), you can ask the proctor to get help. This type of inquiry is not deducted. 3. If the synthesis experiment fails, the following choices can be made: (1) The invigilator consents to redo, not deduct points. (2) Request for rough products with 5 points deducted. (3) It is required to provide a synthetic final product, followed by 8 points for analysis experiments.
