The quantum toroidal action on the Fock space depends on a certain parameter κ.
      
We find that with a specific choice of this parameter, the action on the Fock spaces gives rise to the toroidal action on irreducible level-1 highest weight modules of the affine quantum algebra.
      
Similarly, by a specific choice of the parameter, the level (1,0) vertex representation of the quantum totoidal algebra gives rise to a structure on irreducible level-1 highest weight-modules.
      
As a consequence, there is either a unique set, or an (almost) unique two-parameter set of Weyl group invariant quantum zonal spherical functions associated to an irreducible symmetric pair.

The main advantages of Casson Model are its strong suitability, its convenience in calculation, its high accuracy and its better capability of reflecting the rheologic laws of drilling fluid at different shear rates. The principal rheologic parameters in the model are closely related to the properties required by drilling fluid when it is in motion and at rest. Owing to the fact that the model was used in drilling fluid not long ago, there are no completely agreed opinions on it. Based on the articles published...

The main advantages of Casson Model are its strong suitability, its convenience in calculation, its high accuracy and its better capability of reflecting the rheologic laws of drilling fluid at different shear rates. The principal rheologic parameters in the model are closely related to the properties required by drilling fluid when it is in motion and at rest. Owing to the fact that the model was used in drilling fluid not long ago, there are no completely agreed opinions on it. Based on the articles published already, this paper gives different opinions on the basic meaning and the calculating method of the theologic parameters in Casson Model, and this is for reference only.Necessary descriptions are given of the ability of Casson Model to carry cuttings and the degree of its shear thinning, and preliminary conclusions are also arrived at.

卡森模式的主要优点是适应性强、计算方便、准确性高,能较好地反映钻井液在不同切变率下的流变规律。模式中的主要流变参数和钻井液流动与静止时所要求的特性有密切的关系。鉴于这种模式使用于钻井液的时间不长,认识还不完全统一。本文根据已发表的文章,对卡森模式各流变参数的基本含义及计算方法,提出一些不同的看法,供讨论。 本文还对卡森液体携带岩屑的能力、翦切稀释的程度作了必要的阐述,得出了初步结论。

The characteristic features of an experimental bit are related. The experimental bit is the main equipment used in studying the forces to which the journal bearings of the tricone bit are subjected. The experimental bit is designed according to the basic parameters of XHP215ZY-3 type bit produced by the Chengdu Petroleum General Machinery-Building Plant of The Sichuan Petroleum Industry Administration.Through experiments a set of curves are recorded. The radial and axial loads on the big and small journal bearings of each cone are obtained, and the load distribution percentages on the cones and bearings are calculated. The result of data processing has proved the design of the experimental bit to be successful and the recorded curves of load variations with time to be reliable. Meantime, the experiments concerning the influence of vertical relative positions of cones on their bearing loads are described. At the end of this paper, several opinions on the present design of this type of bit are pat forward.

The bench test of three-cone bits and analysis of their bottom hole patterns are the simplest and useful means of checking and improving their design. These means have been used for a long time abroad, but they are used in our country for the first time now.In present paper we have introduced in great detail the measured parameters and the bottom hole patterns of the Sichuan-made threecone bits, such as 8 1/2″ XHP4-1、川, M—9X types, when we used them to penetrate granite, limestone and Sandstone. In addition, we have compared all these results with those we obtained, using bits of 8 1/2″ J44、J55R、F3、 HP51、J77、types, which are made in U.S.A.Besides, in this paper we have presented several photos of bottom hole patterns and various drilling parameters. Through theoretical analysis of them, we have come to some conclusions about the rational teeth arrangement and usage, which may be useful for improving bit design and its usage.
