### 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: Under the condition that the injection pump uses pure water for injection, we recommend that the flow rate of the microfluidic microchip of the common substrate be set below 150 ul/min and the flow rate of the oil phase be set below 50 ul/min.

### 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.
