China started its oil electric survey in 1952. The number of electric survey crews reached 36 by the end of 1950's. Because the main prospects changed from the Northwest to the East of China in early 1960's, and later affected by the "culture revolution", the electric survey crews greatly decreased in number and many crew members Changed their profession. 5 electric survey crews were reestablished at the beginning of 1970's.

China started its oil electric survey in 1952. The number of electric survey crews reached 36 by the end of 1950's. Because the main prospects changed from the Northwest to the East of China in early 1960's, and later affected by the "culture revolution", the electric survey crews greatly decreased in number and many crew members Changed their profession. 5 electric survey crews were reestablished at the beginning of 1970's. The crews conducted not only conventional electric prospecting but also the experiment of direct detecting oil. The electric surveyors have studied certain applied theory of electric prospecting and therefore developed a complete set of digital processing programs. We can see from the 30 years'practice that electric survey still plays an important role in making areal reconnaissance, locating local rise of high resistance beds and researching into electric fault plane under specific condition. It is suggested that magnetotelluric sounding, artificial electric field sounding and other electric prospecting methods should be actively developed, and their comprehensive applications emphasized.

我国于一九五二年始,开展了石油电法勘探工作,五十年代末,石油电法队发展到36个。六十年代初,随着石油勘探重点由西北转向东部沿海,以及后来“文革”的影响,电法队大批的压缩和转业。七十年代初重新集结了五个电法队,不仅继续从事石油电法勘探工作,而且还开展了直接找油的试验工作。这一期间还就电法勘探的某些应用理论进行了深入研究,建立了一整套数字处理程序。从三十年来的电法勘探实践可以看到,电法勘探在区域普查、查明局部高阻层隆起以及在特殊条件下对电性断面的研究等方面,仍然能起到重要的作用。今后,要积极发展和研究大地电磁测深、建场测深等其他电勘探方法,加强这些方法的综合应用。

The quantitative use of Mssbauer spectroscopy is based on the formula S_a/S_b= (C_aC_b/)·(N_a/N_b). Theoretically, if the concentrations of two types of iron atom, N_a and N_b, are known, the relative intensity coefficient (C_a/C_b) will be able to be obtained through experimental determination of the Mssbauer intensities S_a and S_b. In fact, it would often involve difficulties. In the present paper three (C_a/C_b)coefficients are obtained under the following special conditions:1. Four pure minerals, ankerite,...

The quantitative use of Mssbauer spectroscopy is based on the formula S_a/S_b= (C_aC_b/)·(N_a/N_b). Theoretically, if the concentrations of two types of iron atom, N_a and N_b, are known, the relative intensity coefficient (C_a/C_b) will be able to be obtained through experimental determination of the Mssbauer intensities S_a and S_b. In fact, it would often involve difficulties. In the present paper three (C_a/C_b)coefficients are obtained under the following special conditions:1. Four pure minerals, ankerite, olivine, andradite and almandite, were collected, each of which contains the only valence state of iron and gives the only quadrupole doublet in the Mssbauer spectrum.2. The iron concentrations of the minerals were precisely determined by wet chemical analysis.3. Mixture absorbers were prepared, each of which consists of two of the four above-mentioned, minerals, and the contributions N_a and N_b of the two minerals to each absorber with respect to its iron concentration (N_a+N_b) were known with N_a/N_b1.

按定量穆斯堡尔谱学公式:S_a/S_b=(C_a/C_b)(N_a/N_b),若两类铁原子的浓度N_a和M_b是已知的,并通过实验测得强度S_a和S_b,即可求得它们的相对强度系数((C_a/C_b)。但实际上这种测量有很多困难。本文介绍在特殊条件下的若干测量结果。选用铁白云石,橄榄石、钙铁榴石和铁铝榴石四种矿物;它们的含铁量已知,且各自只含有一种价态的铁原子,各自的谱图中只出现一组四极矩双线。制备了混合吸收体,它们各自由上述四种矿物之中的两种组成,每种矿物对吸收体含铁量的贡献N_a和N_b是已知的,并让N_a/N_b 1。若将C_a相对于铁白云石、钙铁榴石和铁铝榴石分别改写为C_(akr),C_(add)和C_(akm),将C_b相对于橄榄石改写为C_(olv),所求得的结果是:C_(add)/C_(olv)=0.964(±0.025),C_(alm)/C_(olv)=0.874(±0.020),C_(akt)/C_(olv)=0.828(±0.015),对这些结果与矿物结构之间的关系进行了讨论。
