Is only the estimated gap with the actual situation there, it can only be used as a reference. In product development and design stage, to identify key components of this approach is a simple solution to quickly find the problem worth considering.

只 is only estimates that, with the actual situation there are differences, the 只 can be deemed to be reference. But the product research and design stage, identifying key components of the way summary Xie quickly find problem is worth noting.

Only is estimated that, still had the dropping variance with the actual condition, therefore only could treat as the reference.But in the product research and development and the design stage, discovers essential spare part this way is the simple solution found the question the method to be worth fa

Only estimates, and the actual conditions there fall, it can only be used as reference. But in product development and design time, identify the key components in this way is a simple solution to quickly find problems worth noting.
