The impacts of printing process and curing condition on antenna resistance are shown as follows: higher resistance of a printing antenna is generated not only by higher print pressure and velocity, which result in inadequate ink transfer, but also by lower curing temperature and shorter curing time, which can result in imperfect combustion of organic vehicles in silver ink.

印刷工艺与固化条件对天线电阻的影响主要表现在：较高的印刷速度与印刷压力会使银浆转移不充分，并导致天线电阻增加；而较低的固化温度、较短的固化时间也会使银浆中的有机载体不能充分燃烧，从而增加天线电阻。

On the basis of the laboratory data and by widely analysing the formation origin and mechanism of low-resistivity oil/gas reservoir, a point of view is put forward which is not consistent with the idea existing for a long time, that is not all the low-resistivity oil/gas reservoir is shaly sandstone. Fine grains or pure fine siltstone can also form the low-resistivity oil/gas reservoir. And the additional conductibility of clay will become the prominent factor that causes the low-resistivity only when the salinity of formation water is lower. Actual cases indicate that when the salinity of formation water is greater than 300000ppm or so, even ifthere is some clay, its additional conductibility can also be ignored.

建立在实验室数据的基础之上，并通过广泛地低电阻率油气储集层成因和机理分析，提出了与长期以来存在于人们头脑中的思想观念不相一致的看法，即认为低电阻率油气储集层并非都是泥质砂岩，岩石颗粒细小的或纯净的细粉砂岩也可能形成低电阻率油气储集层，并且粘土的附加导电性也只有在地层水矿化度比较低时，才会成为造成低电阻率的突出因素，事实表明，当地层水矿化度高于大约300000ppm时，即使储集层含有一些粘土矿物，它所产生的附加导电性也是可以忽略的。
