In this paper, the 3D finite element method (3D-FEM) is employed to calculate the responses of the dual-laterolog in the high angle deviated wells. Moreover, under the consideration of the impracticability of the strict 3D inversion of the electrical logging, one method named the fast deconvolution, is given to correct the electrical logs which is calibrated by the forward method, 3D-FEM.
在考虑常规双侧向测井和正演数值模拟计算的基础上,利用三维有限元素法(3D-FEM)进行大斜度井中双侧向测井响应的数值模拟求解,并以不同倾角为条件验证了方法的有效性;进一步针对目前严格的电测井三维反演处理的不现实性,应用严格正演刻度下的快速反褶积处理方法进行定向井的电测井曲线校正。

Main contents and conclusions are: 1 The ionization current was measured continuously by a charge-integration method with a computer after the introduction of radon into the chamber.
主要内容及结论:1充氡后利用计算机连续进行电离电流累积测量,得到了精细的电流随时间的变化曲线,可清楚看出氡及其子体的生成衰变造成的电离电流的生长—稳定—衰减过程,与理论计算值进行了比较,由电离电流衰减速度的变化得出氡吸附作用的影响,并测量到电离室冲洗后氡的反扩散现象;2由已知活度的标准源定出相对测量的刻度系数K值,K=24.62 Bq/pA,对同一个监测源以半年为周期进行多次测量后得出稳定性符合要求;3通过测量电离电流和气压的关系曲线以及不同气压下的饱和曲线,确定了常规的工作条件;4测量了盐酸清洗电离室内表面降低本底的效果;5不确定度分析表明相对测氡的扩展不确定度(k=2)小于5%,由本底涨落得出探测下限为0.5 Bq;6理论上对壁损失修正进行了计算,实验上保持电离室工作在饱和区的情况下,测量了不同气压下电离电流的变化,从中得出了壁损失随气压变化的规律,可以看出,电离电流的实测值和计算值随气压变化规律基本一致;当气压大于125 kPa时,端效应等其它因素造成的影响不大于2%,因而在此工作条件下,测量电离电流后通过计算修正壁损失可以实现近似的绝对测氡,提出了进一步提高绝对测量准确度的方法。

Its measurement is the measurement of time, the status of the translucent screen Department or looking at the version will mesh ruler in wire mesh network, and then set the gauge wire edge network, so that the vertical line on the screen ruler and MEST warp or weft parallel, at which point due to the mesh screen coordinates and produces overlapping on vertical ruler that formed over the mesh inferion-edged chevrons patterns within the meaning of the transverse diagonal mesh feet on the scale of numbers, that is, the measured screen mesh size.
其丈量办法是:丈量时,首先使丝网处在透亮的状况下或不收在看版台下,不兵网纲尺不收在丝网上,然后不兵网纲尺在丝网上匆匆安放,使网纲尺上的竖线与丝网的不经线或经线交错,这时由于丝网经经线和网纲尺上竖线爆发重叠成果,在网纲尺上变成棱形斑纹,斑纹的横向对角所指的网纲尺上对应的刻度数字,即是所测丝网的纲数。

It is indicated that the accuracy of the measured value is determined rather by the practical relative error than by the maximum relative error. It is correct that the nearer the scale reading approaches the maximum, the more accurate the measurement is. The scale reading need not be required above 2/3X.
指出使用电表进行测量时,测量值的准确性是由其实际相对误差而非最大相对误差决定的;并非电表的读数越接近满刻度,测量值的准确性就越高;使用电表进行测量时,电表的读数不必被限定在2/3X上。

In this paper , the statistic significance and clinical application of forest plots in a meta-analysis have been fully discussed. If the horizontal line represents the 95% confidence interval of the indexes including odds ratio, relative risk, weighted mean difference, and standard mean difference crosses the vertical line, the effect of test group is not signficant with that of control group; if the horizontal line lies to the right of the vertical line, it indicates that the test group is significantly effctive. If the horizontal line lies to the left of the vertical line, it indicates that the control group is more effective.
对Meta-分析的森林图的统计学意义和临床应用做了较为详细的解释:当统计指标比值比、相对危险度、加权均数差和标准化均数差的95%可信区间横线与森林图的无效线(横坐标刻度为1或0)相交时,试验组的效应量等于对照组,试验因素无效;当其95%可信区间横线不与森林图的无效线相交且落在无效线右侧时,试验组的效应量大于对照组;当其95%可信区间横线不与森林图的无效线相交且落在无效线左侧时,试验组的效应量小于对照组。
