A sds-iso-propanol method suitable for tea plant, which was plentiful of tea polyphenols, had been developed using a modification of chen darning's method from different sample storage conditions such as fresh, dry and frozen shoots . it was a quick, easy, economical and effective method . the tactics were as follows : before the cell nuclear membranes were decomposed, the tea polyphenols and proteins etc . were removed 該法提取緩沖液使細胞維持一定的滲透壓,研磨時使細胞核基本保持完整;在細胞核被裂解之前去除細胞質中的茶多酚、大部分蛋白質和rna;而后用sds裂解細胞核,異丙醇或乙醇沉淀dna,這樣能經(jīng)濟、快速和有效地從富含茶多酚、茶多糖等次生物質的茶樹新梢中提取基因組dna。
A new model about measuring harmonics on-line is proposed in this paper . after band pass filtering, sampling storage and the monitoring on-line with artificial neural network ( ann ), we can obtain the harmonics signal, which is used to compensate harmonics . using the basic principle of analog parallel harmonics measurement and a special multi-layer feedforward neural network, a corresponding harmonics measurement on-line is built 在本文中提出了一種新型電網(wǎng)諧波監(jiān)測系統(tǒng)模型,通過帶通濾波器,采樣存儲器以及神經(jīng)網(wǎng)絡組成的監(jiān)測系統(tǒng)可以實時監(jiān)測電網(wǎng)諧波,當電網(wǎng)中的3次、5次、7次諧波超過容許值時,給出控制信號啟動以記錄儀記錄諧波,并可以控制諧波補償,最終達到監(jiān)督電網(wǎng),抑制諧波、減小諧波的目的。
