fdv

Following the heating section of the HTST system , the product reaches a flow diversion valve ( FDV ) .

经过HTST设备的这个加热段以后，产品到达流量转向阀（FDV）。

The FDV is controlled by a temperature-sensing device located at the exit of the heating section of the system .

加热器能散发出热能。FDV受一个设置在设备加热段出口的温度传感器控制。

I can replace that FdV Now , I need to tell you what the divergence of a3D vector field is .

，现在我需要告诉你们，三维向量场的散度是什么。

If the product has reached the desired pasteurization temperature , the FDV will maintain forward flow and product will move to the next component of the system .

如果产品达到所需的巴氏杀菌温度，那么FDV将保持原来流向，产品会移到设备的下一个部分。

Clinical efficacy ( daily emiction frequency , nocturia frequency , urgency and odynuria degree ) and urine kinetic parameters ( FDV , MCC , Qmax ) of the 2 groups before treatment , 1 month and 3 months after treatment were evaluated .

观察两组用药前、用药后1月、用药后3月的临床症状（每日排尿次数、夜尿次数、尿急和尿痛程度）和尿动力学参数（FDV、MCC、Qmax）。
