一般来说,甩挂运输效率越高,半挂车与牵引车的比例就越高。据相关统计数据显示,我国半挂车与牵引车的比例大约是1.12:1,几乎是很少有甩挂。而我国的甩挂运输比例小,除了政策环境需要改善外,还需要注意半挂车与牵引车之间的机械匹配参数需要合理化、互换性需要标准化
In general, the higher the efficiency of rejection transport, the higher the ratio of semi-trailer and tractor. According to relevant statistics, the proportion of semi-trailers and tractors in China is about 1.12: 1, with almost no hanging. In our country, there is a small proportion of thrown-off transport, in addition to the need to improve the policy environment, but also need to pay attention to semi-trailer and tractor between the mechanical matching parameters need to be rationalized, interchangeability needs to be standardized

本文讨论了橙汁中康唑类杀菌剂（包括多菌灵）的样品制备策略。首先，使用QuEChERS方法的DisQuE产品进行样品制备，用以检测各种水果、蔬菜和果汁中的杀虫剂含量。结合QuEChERS方法，UPLC/MS/MS可以轻易检测出10μg/L（ppb）包括多菌灵在内的5种康唑类杀菌剂，且无需进行进一步的样品制备操作。QuEChERS提取液可以作为前体样品，然后进一步净化并使用液相色谱UV检测器分析其中p
