偶然性误差
- 网络accidental error;spontaneous error
偶然性误差-
该装置可以实现多个反应釜在在相同压力、温度下反应，可以大大减小实验的偶然性误差；操作简单，可以快速筛选抑制剂和确定其最佳用量。
Several reactors are at the same pressure and temperature , which can greatly reduce the accidental error , simplify the operation , select inhibitors and determine the optimum dosage quickly .
