加速度计nano与pico与femto的差异是什么

我认为，这些都是更多的营销术语。
我宁愿使用以下矩阵代替。
也可以找到产品选择器

。

.

如果它们只是营销术语，那么产品摘要表似乎有点混淆似乎强调分类如此突出。如果我看一下LIS2DW12的页面，
http://www.st.com/content/st_com/en/products/mems-and-sensors/accelerometers/lis2dw12.html
 ，我在前几行告诉我这个项目是'femto'家族的成员。但是如果没有对这意味着什么的定义，那么告诉我信息是无用的甚至是混乱的，因为我读到的第一件事就是“'femto'是什么意思？我应该已经明白了吗？有没有解释它的词汇表？ 'femto'比'pico'更好吗？'除非有一页解释了这些家庭之间的差异，否则提及它绝对没有营销价值。



以下为原文




If they're just marketing terms, then it's a bit confusing for the product summary sheet to seem to emphasize that categorization so prominently. If I look at, say, the page for the LIS2DW12,
http://www.st.com/content/st_com/en/products/mems-and-sensors/accelerometers/lis2dw12.html
, I am told in the first few lines that this item is a member of the 'femto' family. But without a definition of what that means, then telling me that information is useless and even confusing, since the first thing I thought of when I read that is, 'What does 'femto' mean? Am I supposed to already understand that? Is there a glossary that explains it? Is 'femto' better than 'pico'?'Unless there's a page that explains the difference between those families, there's absolutely no marketing value in mentioning it.
