查询词典 ammelide

Melamine and its analogues - cyanuric acid, ammelide and ammeline - are assumed to be of equal potency and are referred to collectively below as melamine-analogues.

三聚氰胺和它的类似物－尿氰酸、酰胺、三聚氰酸二酰胺－被假定为具有同等效力，以下统称为三聚氰胺类似物。

A HILIC-MS/MS method was developed to determine melamine and its three derivatives, cyanuric acid, ammelide and ammeline in milk and milk powder. The milk sample was directly extracted by acetonitrile with the help of ultrasonic, and milk powder was resolved in water before extraction by acetonitrile.

建立了牛奶和奶粉中三聚氰胺及其3种衍生物（三聚氰酸、三聚氰酸一酰胺、三聚氰酸二酰胺）的亲水色谱－串联质谱检测方法(HILIC-MS/MS)。

After centrifugation, the extracts were separated on HILIC column by using acetonitrile-water as mobile phase. The analytes were identified and quantitated by LC-tandem MS under the positive/negative electrospray ionization and multiple reaction monitormode. The calibration curves showed good linearity in the range of 25-5000 μg/kg for melamine and cyanuric acid, and 50-10000 μg/kg for ammeline and ammelide. The limits of detection and limits of quantification were in the range of 5-20 μg/kg and 50-100 μg/kg, respectively.

牛奶样品直接用乙腈超声波提取；奶粉样品先用水溶解后再加乙腈超声波提取，高速离心后以乙腈－水为流动相，采用亲水作用色谱柱分离这4种化合物，在电喷雾正、负电离切换多反应监测模式下进行定性与定量分析，三聚氰酸一酰胺与三聚氰酸二酰胺含量在50~10000μg/kg之间、三聚氰胺与三聚氰酸在25~5000μg/kg之间，均获得良好的线性。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
