ABSTRACT This paper describes the gammaspectrometrie well-logging method,apparatus and software, which were originally developed for exploration of potash salt.But it could be used as well for other purposes,such as:the exploration of uranium,the study of geologieal strata.the detection of water-bearing gravel strata or of fractured zones and so on.
Owing to the severe shortage of the potash fertilizer in China during the past more than 30 years great attention has been paid to the study of new methods,including gammaspectrometric well-logging.The gammaspectrometric well-logging method and bore-hole gammaspectrometer were proposed and developed by us in 1963,and several times updated up to the eighties.5 types of the bore-hole gammaspectrometer were developed:single-channel, double-channel and four-channel moddels for both shallow and deep bore-holes.This method has been applied in 6 provinces succesfully.A bore-hole radioactivity-spectra interactive interpretation software system（HRSIS）was de-veloped in 1995,whjch consists of 5 groups of functional programs:the preprocess.the quantitative interpretation.the trend analysis,the graphic display and the integrated interpretation.
Key words:Bore-hole gammaspectrometer,Gammaspeetrometric well-logging method,Gammaspectrometric well-loging software.
METHOD
According to the statistics more than 50%of the total world reserve of sylvinite were discovered in bore-holes.For revelation of sylvine and differentiation of it from the argillaceous thorium-uranium-hearing rocks the gammaspectrometric well-logging method was studied and the bore-hole gammaspectrometer was developed since 1963 and 5 times updated up to the eighties.
It is the natural radioactive isotope Kafter 3600m cable transfer kept the same level of resolution（10%）as without the long cable.
* Stability.The vertical temperature gradient of the earth is about 1 degree Centigrade for each 33 m,so at the depth 3500m the environmental temperature in bore-hole can be as high as 100 degrees Centigrade.For the reliable stabilization of the spectrometer the following 3 measures were adopted:the selective use of high temperature NaI crystal and photomultiptier；the compensation of the negative temperature coefficient of the photomultiplier by the positive temperature coefficient of the high voltage source for the photomultiplier；and the use of an autostabilization circuit for isotope Cs137 to keep the spectral peak position.
Any photo-peak of an isotope is added on the compton continuum of photo-peaks with higher energy.It is the theoretical base of the stripping method and the principal component analysisfor K,that the background is proportional to the RI（Fig.1）.
SOFTWARE
A bore-hole radioactivity-spectra interpretation software system（HRSIS）was developed in 1995, which consists of 5 groups offunctional programs:the preprocess（A: PRP）,the quantitative interpretation（B:KTU）,the trend analysis（C:TRD）,the graphic display（D:GRP）and the integrated interpretation（E:ITR）.The sixth group is for the HELPs（F:HLP）.The HRSIS system was written on PCs with C language.Fig.2 shows the functions of this HRSIS system.

For quantitative interpretation both double-window and three-window methods were used.Fig.3 illustrates the well-logging image,as one example of the processing results by HRSIS system.On this image（Fig.3）2 KCl layers at depths 274m and 325m are revealed by high LI,high PK,high TC and low Rl.Fig.4 displays the correlation profile by tend analysis curves for RI and LI,where the periods of lake sedimentation are seen clearly.Fig.5 is the scattergram of Th and K concentrations,determined by functions of group B:KTU.

APPLICATIONS
Gammaspectrometric well-logging method has been applied in 6 provinces（YunNan,HuBei.SiChuan.ShanDong,XinJing and QingHai）successfully.The sylvinite-bearing layers with thickness=＞0.5m and KCl concentration=＞2%can be detected bv bore-hole gammaspectrometer reliably in MengYeJing and other salt deposits.The policy of“Exploration for both Oil and Sylvite Concurrently”was made by Ministry of Petroleum of PRC.Following this policy a aphthitalite layer with thickness 0.8m and KCl concentration as high as 16.8%was found in JiangHan oil field using this gammaspectrometric well-logging.In province SiChuan the ischelite layers with thickness of=＞0.2m were detected.
In 1991 in YunNan province in a new drilling area,when all of the drilling core of the first borehole was lost,only thanks to the gammaspectrometric well logging a big amount of money was saved by avoidance of redrilling.
This method can be used as well for other purposes,such as:the exploration of uranium,the study of geological strata,the detection of the water-bearing aquifers or of the fractured zones and so on.

强化学习中 value based和policygradient的区别
，off-policy和on-policy的根本区别在于off-policy学习的policy和agent实际执行的policy并不相同。虽然看起来很trivial，但这给了off-policy极大的发挥空间，使RL有能力做knowledge representation。假设有一个机器人在地面上行走，我们想知道在某个状态时如果机器人停止动力系统，需要多久才能完全停下来。我们可以构造一个policy，action永远都是停止动力系统，reward是每个time step为-1，那很显然在某个state下机器人停止所需的时间就是在我们构造的这个policy下的v(state)。我们可以有很多类似的问题，同样我们需要构造很多类似的policy来回答这些问题。这些policy的value function一般称作GVF(general value function)，可以作为knowledge representation。但问题在于怎样学习这些policy，由于数量巨大，显然不可能对每个GVF进行on-policy的学习，此时便可以利用一个exploration很强的behaviour policy进行off-policy学习。希望对你有帮助~
