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。

Method Task time, selected error and timeout numbers were recorded automatically, when 12 participants were performing the task of target selection, with different object size, space and dwell time.

方法12名被试者在对象大小、对象间距和驻留时间的不同处理水平下，通过眼动完成目标选择任务，由计算机自动记录作业时间以及选择错误和超时数目。

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 input range, dwell time, the acquired channel of the module can be controlled according to the need.

数据采集模块的输入范围、采样时间、采集通道都可以根据实际需要进行控制。

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。

The results show that the thermal fatigue life decreases with enlarging the thermal cycle dwell time, the thermal cycle range and the maximum dwell temperature, and the minimum life is 879 cycle.

结果表明：随着热循环高低温停留时间、温度范围以及最高热循环温度的增大，热循环寿命减小，最小寿命为879周；

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

But Trins had no time to dwell upon this.

不过屈丽娜没工夫来多想这件事.

With the as-sumption that the subsystems are Hurwitz stable and Schur stable, if the average dwell time is properly large, the switched system can be made stable.

在假设所有的子系统都是Hurwitz和Schur稳定的前提下，如果平均停留时间足够大，则切换系统就可以达到指数稳定。

It can improve solubility and stability of drugs, reduce immunogenicity and proteolysis, greatly increase circulation time and improve efficacy due to increased concentration and longer dwell time at the site of aion.

它可以改善药物的可溶性和稳定性，减少免疫原性和蛋白水解，显著增加体内循环时间，以及在作用部位提高药物浓度和延长驻留时间从而提高疗效。

Show that design condition of switching periodic under dwell time of all subsystems are equalization.

同时当各子系统的驻留时间均等时，得到了切换周期的设计条件。

The thermal cycle dwell time, thermal cycle temperature range and the maximum dwell temperature were changed to observe their effects on the thermal fatigue life of solder joint; the length and thickness of substrate were also changed to research the dimension effect.

通过改变热循环保温时间、温度范围和最高温度，研究各参数对焊点热疲劳寿命的影响，同时也考察了基板的长度和厚度的影响。
