该方法的推导思路是：假设在某一控制储量条件下，联立求解气藏物质平衡方程式和气井二项式采气方程，计算气井采气曲线并将其与实际的采气曲线相匹配，最后确定储量、产能参数。该方法不需要较长的多次关井复压资料，在气藏受水驱影响较小时，还可计算一口探井或气藏试采早期所反映出的气井控制储量，在气藏生产中得到应用，计算结果较为可靠

There is neither paper about detecting DsMV by DBH or IC-RT-PCR nor report about comparing ELISA with these methods published before. Therefore, the DsMV detection methods developed in this study can be applied to virus certification scheme of calla lily and help to produce healthy seedlings in Taiwan.
