Pesticides were extracted from tea with hexane-acetone (volume ratio is 1:1) in an ultrasonic bath and cleaned up on a Florisil and neutral alumina column, then were determined by gas chromatography with negative chemical ionization mass spectrometric detection in the selected ion monitoring mode, and with heptachlor epoxide as the internal standard. Spiked blank samples were used as standards to counteract the matrix effect observed in the chromatographic determination.

茶叶试样用V/V=1/l混合提取剂超声提取，经Florisil矽藻土和中性氧化铝混合层析柱净化后，以环氧七氯为内标物，采用GC-NCI-MS的选择离子监测方式分析；探讨了茶叶试样的基体诱导色谱响应增强影响所产生的分析误差及其减小的措施，用空白试样基体匹配校准曲线法定量分析。

A front-back seal ring structure is adopted in the pump to prevent the liquid from leaking from the high-pressure area to the low-pressure area. The front seal ring is mounted on the pump body while the back seal ring mounted on the bearing body. They should be changed when they are so worn-out that they have an effect on the efficiency and self-priming performance of the pump after the operation for a long time.

泵内部防止液体由高压区向低压区泄漏的密封机构是前后密封环，前密封环装在泵体上，后密封环装在轴承体上，当泵经长期运转密封环磨损到一定程度，并影响到泵的效率和自吸性能时，应给予更换。
