求翻译：若考慮時間因素，可採用常用之標準來進行預估。但由於電子產品發展快速，電子零件每年推陳出新導致計算公式有待商榷。是什么意思？

Considering the time factor, can be commonly used standard estimates. However, due to the rapid development of electronic products, electronic parts in each of innovation lead to the calculation formula is open to question.

If time factor for the common subject to predict standards. But since the electronic product development of rapid, electronic parts innovation each year, according to a formula led open to question.

If the consideration time factor, may use the commonly used standard to carry on the estimate.But because the electronic products development is fast, the electronic components weed through the old to bring forth the new to cause the formula pending discussion every year.

Taking into account the time factor, can be estimated using common standards to. But, due to rapid product development, innovation led to a year of electronic parts formula open to discussion.
