FDV

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。

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。

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 ).

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）。

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。

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）。
