焊料微互连在热周期和跌落冲击顺序载荷下的可靠性研究更具有实际意义。
The sequential thermal cycling (TC) and drop impact test is more reasonable to evaluate the reliability of lead-free solder interconnections compared with single TC test or drop impact test.
避免生周期:这个超级热周期,可在某些型号,增加了能源的使用显着,所以只有使用它时绝对必要的。
Avoid the sanitary cycle: This super hot cycle, available on some models, increases energy use significantly, so only use it when absolutely necessary.
太阳活动的周期是11年。新数据表明,在一个周期末期太阳活动趋弱时,抵达地球的光与热的量增加而不是减少了。
As solar activity waned at the end of one of the Sun's 11-year cycles, the new data shows the amount of light and heat reaching the Earth rose rather than fell.
