Methods by using a broad pH range column(Gemini NX C18,4.6mm×150mm,5μm),basic mobile phase which was[H_2O-ammonia-glacial acetic acid] (96:3.6:0.4)-methanol,the related substances in etimicinsulfate were separated and detected by electrospray ionization and positive ion monitoring,the ESI ion source condition was following: temperature is 350℃,nebulizing pressure is 50 psi,dry gas flow is 10 L /min.some related substances in etimicinsulfate were identified by comparing the retention time in chromatography,~+ spectrum and MS~2 spectrum with reference substances\',the others which haven\'t reference substances were identified or speculated by analyzing their MS~2 fragmentation with the help of a rule summarized from the MS~2 fragmentation of gentamicin C1a,micronomicin and etimicin.Results nineteen related substances in etimicinsulfate were separated and detected.

方法利用宽pH范围的Gemini NX C18(4.6mm×150mm，5μm)色谱柱，在碱性条件下，以[水-氨水-冰醋酸(96：3.6：0.4)]-甲醇(70：30)为流动相，直接分离各组分；并用HPLC-ESI-MS~2检测样品中各组分，质谱条件：ESI离子源，离子源温度350□，雾化室压力50 psi，干燥气流速10 L/min，正离子检测方式；对有对照品的有关物质采用比对有关物质与对照品的色谱保留时间、准分子离子的质荷比及二级质谱方法进行鉴定，无对照品的有关物质，则是先通过解析庆大霉素Cla、小诺霉素、依替米星的二级质谱，对该类化合物的二级质谱裂解规律进行归纳，并以此推测未知新化合物进行结构，再用推测的结构对二级质谱进行解析，如所有的碎片离子均合理解释，表明推测合理。

Almost all CF was released from Dansyl-PE by CTX-IX that osmosed the Dansyl-PE liposome like detergent; CF releases from PE or PS liposome induced by CTX-IX were related with both of CTX-IX and phospholipid concentrations, this indicated that the phase seperation should be a reasonable mechanism for CF permeability of PS or PE liposome in the presence of CTX-IX rather than CTX-IX channel formation on the membrane. CTX-IX influence of CF release of PC liposome was very slight. CF release from Dansyl-PE、PE or PE liposome in response to CTX-IX could be inhibited by Ca〓.

CTX-IX对靶脂如此种种强烈的作用，使得它引起含Dansyl-PE脂质体CF的泄漏犹如击污剂那样强烈；引起含PS或PE脂质体CF渗透的增加为一个与CTX-IX及磷脂浓度有关的二级反应过程，这种动力学特征提示渗透性增加的机制可能是CTX-IX在脂膜上产生的脂质分子相分离，而不是CTX-IX脂膜上形成通道；CTX-IX对PC脂质体渗透性几乎没有影响，而对上述脂质体渗透性增加作用均可被Ca〓所抑制。

Diacetyl cellulose was blended with PHBV in mixture of chloroform/acetone. It was a failure to improve the mechanical properties of the blends, because the hydrogen bond between CDA and PHBV was very weak, and there was obvious phase separation in the blends..

二醋酸纤维素与PHBV经溶液共混，PHBV的力学性能没有改善，原因可能是CDA-PHBV分子间的氢键作用较弱，组分间发生严重相分离，不利于性能提高。
