当日凌晨3时46分，沪渝高速宜昌往恩施方向崔坝服务区2公里处一辆载有二甲苯的槽罐车发生侧翻，二甲苯随即泄漏出来，带有浓烈刺激性气味的二甲苯在现场扩散。4时54分，恩施消防官兵到达现场，根据二甲苯具有高闪点、易燃、有毒、有挥发性且不溶于水的特点，现场指挥员命令消防车停靠在事故区上风方向。

On the basis of volatile odor of storage fish, four-gas sensor arrays (TGS822 for ethanol; TGS825 for H2S; TGGS826 for NH3 and aime, TGS832 for halocarbon) were selected as the nose of electronic nose system, the electronic nose measurement system was constructed based on LabVIEW, then silver carp meat during storage was investigated by using this system. The results indicate that the response of electronic nose is correlated with freshness loss of fish.
