### Chinese: 普通基底的微流控微芯片在注射泵使用纯水进样的条件下，我们给您的建议流速设置在150ul/min以下，油相流速建议设置在50ul/min以下。
### English: For microfluidic microchips with common substrates, we recommend a flow rate of 150ul/min or less for syringe pumps using pure water, and 50ul/min or less for oil phase.
### Errors: There is no error in the English translation.

### Improved English: In condition of sample injection with pure water for micro-fluid chips of ordinary base, you are recommended to set the flow velocity as under 150ul/min and set the flow velocity of oil phase as under 50ul/min.
