### 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: Microfluidic microchip with ordinary substrate <v>Under</v> the condition that pure water is injected into the injection pump, we recommend that the flow rate be set below 150ul/min, and the oil phase flow rate be set below 50ul/min.
### Errors: There is a minor fluency/spelling error at "Under" within <v></v>.

### 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.
