dwell time

Reaction parameters have been optimized in the research. Different from the foreign process, this process carries out at low reaction temperature, MHF/ MR30, and short dwell time.

研究中对反应参数进行了优化，与国外工艺不同，该工艺选用了较低的反应温度、MHF/MR30及较短的停留时间。

The range, stepped frequency and dwell time of sweep frequency could be set by software.

频率扫描范围，频率步进和驻留时间等参数可由软件设置。

Optimizing Analyse on Dwell-Time Parameters

驻留时间参数优化分析

When dell time and temperature range dwell was fixed, the fatigue life of critical solder joint was the function of ramp rate.

在保温时间和温度范围不变的情况下，关键焊球的疲劳失效寿命是升降温速率的函数。

But Trins had no time to dwell upon this.

不过屈丽娜没工夫来多想这件事.

Then, a Box-Behnken design by using Design-expert software was conducted, we selected mold temperature, melt temperature, holding pressure and dwell time as experimental factors, selected warpage and shrinkage as target variable.

其次，运用Design-expert软件设计了Box-behnken试验，选取模具温度、熔体温度、保压压力、保压时间作为实验因素，以翘曲变形和体积收缩率作为目标变量。
