Content question: there is no space in the universe, we observed with space is matter and field components space, the expansion of space is substances and substances in the expansion of the field, all moving substances and substances will be in a field-the-field sport, including light and electromagnetic waves, like automobile from the disconnexion in the same way, there is no absolute vacuum of space, there is no absolute coordinate system, all substances campaign has been relative motion.

内容题要：宇宙是没有空间的，我们观测的空间是物质和场物质组成的空间，空间的扩大也是物质和场物质在扩大，所有运动的物质和场物质都会在一个场上运动，其中包括光和电磁波，好象汽车离不开路一样，不存在绝对真空的空间，也没有绝对坐标系，所有物质运动都是相对运动。

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。

On the basis of tri-division of natural substances into human beings, inartificial substances and man-made substances, their interactions, especially the roles that man-made substances play, are discussed, and methodological foundation is set up to build the harmony between human beings and nature.
