In other words , when the same field source is observed in a different frame of reference , electric field or magnetic field will possess a different nature ; whereas when the frame of reference changes , they may change into each other 即同一场源在不同的参考系中观测，所得的电场或磁场具有不同的性质；而当参考系变换时它们可以相互转化。
That shows there are some difference in the steroid regulation between the anuras and the urodeles . among three of the steroid , one can convert to the other , and some enzyme activity is concerned with the conversion 三种类固醇激素存在相互转化的关系，睾酮可能在雌二醇和孕酮的转化中起着底物的作用，这种转化与某种芳香化酶的活性有关。
The more general graded approximations and variable precision approximations are defined in approximate space . the relationship between them is researched , and the important formula of conversion is achieved 在近似空间中定义了更一般的程度近似和变精度近似，研究了两者各自的性质和相互关系，得到了程度近似与精度近似相互转化的重要公式。
There have very relativity in all kinds of threshold index , when other condition don ? change , different index as peak hour volumes , vpd , the size of new development and los etc may be interchangeable 在阈值中各类指标之间具有很大的相关性。当其它条件一致时，不同指标，如高峰小时交通量、 vpd （日交通量） 、设施的开发规模、 los摘要一等可以相互转化。
( 2 ) describing the three mode for control and management of companies in the world in detail , and based on comparing their evolution and existence conditions pointing out the conversion into each other 对当前世界上主要的三种公司治理模式进行了较为详细的描述和总结，并在比较各自演变的过程和存在的条件的基础上，指出了三种模式之间的相互转化关系。
Chapter 2 expounds the contradictions and their embodying of the fiscal fund and bank fund in the transition period from the point of historical view . chapter 3 is about the transform of the fiscal risk and bank risk 第三章分两个方面介绍了财政资金与银行资金运行矛盾的直接后果，即由于历史的，体制的原因我国目前的财政风险与银行风险存在相互转化的机制。
On the one hand , it may provide the direction for choice of method of studying economic law ; on the other hand , it is an important part of economic law theory may convert mutually with economic law theory under the particular condition 一方面,它可以为经济法学方法的选择提供指导;另一方面,它与经济法学理论在一定条件下可以相互转化,是经济法学理论中的重要组成部分。
There is generality in individuality , they can transform themselves into another under limited conditions . individuality is relative and reflected in the relations among people , it is the trendency of humanization and the aim of developing individuality is to reach a better communication 个性有共性的一面，在共性里出类拔萃，也应该是个性，二者可以在一定条件下相互转化，个性是相对的，在跟人相处中体现。
Enzymatic assay were performed using recombinant proteins expressed in e . coli cells . tilapia 17 - hsd1 is nadp ( h ) dependent and it can catalyze the interconversion from estrone to estradiol efficiently and also from androstendion to testosterone but less efficiently 酶活性实验结果显示，在e . coli细胞中表达的17p一hsdi / petbluez重组蛋白既能高效地催化a和t之间的相互转化，同样又能更高效地催化e1和ez之间的相互转化。
17 - hsd8 / pcdna3 . 1 recombinant protein expressed in hek 293 cells and it can slightly interconvert estrone to estradiol . moreover , it can catalyze the conversion from testosterone to androstenedione . however , 17 - hsd3 did n ' t show any conversion to all the substrates checked in this study 而17p一hsds转染hek293细胞表达的17p一hsds / pcdna3 . 1重组蛋白能微弱地催化el和ez之间的相互转化，同时也能催化从t到a的氧化反应。
