The infrared spectra of more than thirty pure saturated hydrocarbons were determined. The equations in terms of average absorption for calculating the composition of CH_3, CH_2, CH_2 and CH_2 groups in saturated hydrocarbons were obtained by using least squares method in matrix form.Comparing the results calculated from the equations mentioned above with the theoretical values of known mixtures and pure compounds, it is shown that the error of such method is as follows: CH_3<±4%, CH_2<±5%, CH_2 and CH_2 <±10%.The...

The infrared spectra of more than thirty pure saturated hydrocarbons were determined. The equations in terms of average absorption for calculating the composition of CH_3, CH_2, CH_2 and CH_2 groups in saturated hydrocarbons were obtained by using least squares method in matrix form.Comparing the results calculated from the equations mentioned above with the theoretical values of known mixtures and pure compounds, it is shown that the error of such method is as follows: CH_3<±4%, CH_2<±5%, CH_2 and CH_2 <±10%.The abnormal phenomena observed from the absorption of the methyl groups on the branched chain at 1340—1400 cm~(-1) were discussed. The absorption coefficient of these methyl groups on the branched chain is about 2.8 times that of the normal methyl groups.The absorption for normal paraffins at 3000 cm~(-1) was found to be consistent with the results reported by Jones, when the value of computed spectral slit width/observed half width of the spectrum (s'/Δν_(1/2)~a) is not more than 0.2. Therefore, this spectral condition may be used as a standard for the intercommunity of spectral data from different laboratories.

根据30多个纯饱和烃的红外光谱数据以及文献数据,并将短阵运算用于最小二乘法,求出了测定饱和烃中CH_3,CH_2,和结构族组成的多重迴归方程式.可用来分析石油馏分饱和烃的结构族组成.经用单体烃和配制的饱和烃混合物校验,求得平均分析误差如下:CH_3<±4%,开链CH_2<±5%,及。讨论了饱和烃支链甲基在1340—1400厘米~(-1)区吸收的反常现象,计算出支链甲基吸收为尾端甲基的2.8倍.在计算光谱狭缝宽度/谱带表观半宽度≯0.2的情况下,所得吸收率与Jones的正烷烃在3000厘米~(-1)处的数据相吻合,作者认为此条件可能成为统一各实验室测定液态烷烃红外光谱数据的标准.

Estimating quantitatively signat to noise ratio (S/N) of seismic record is more and more important in that a high resolution seismic exploration can be conducted more efficently and a high quality seismic section with high resolution and high S/N ratio can be provided for interpreting the lithology and structure of a stratum. Under the presupposition of supposing the noise is stochastic and white, two methods to estimate the S/N ratio in quantity from the seismic date section are applied in this paper, one is the correlation method, the other is the statistical averaging method. The measure to deal with residual NMO (normal moveout) and residual status is considered. The theoretic date models are used to verify the two methods at the final in this paper.

定量分析地震记录的信噪比,能更有效地进行高分辨率地震勘探,并为地层岩性和构造解释提供高分辨率、高信噪比的优质剖面。在假设噪音为随机白噪的前提下,使用相关分析法和统计平均分析法定量地估算(其中考虑了动校正和静校正不准确及界面非水平的情况)地震记录的信噪比。文章还用理论模型对这两种方法进行了验证,表明这两种方法在几种不同信噪比的条件下,其估算值与理论值比较吻合
