Geometric characterizations for variational minimization solutions of the 3-body problem被引量:2
《Chinese Science Bulletin》1999年第18期1653-1655,共3页LONG Yiming and ZHANG Shiqing1. Nankai Institute of Mathematics , Nankai University , Tianjin 300071 , China  2. Department of Applied Mathematics, Chongqing University, Chongqing 400044, China Associate Member of the ICTP. 
For any given positive masses it is proved that the variational minimization solutions of the 3-body problem in 3 or 2 are precisely the planar equilateral triangle circular solutions found by J. Lagrange in 1772, and...

ON INTERPOLATION OF A CERTAIN CLASS OF FUNCTIONS
《Chinese Science Bulletin》1992年第18期1580-1581,共2页朱尧辰 
Project supported by the National Natural Science Foundation of China.
For a real a, let =max(1, |a|). Let s≥1. We use Gs to denote the s-dimensional unit cube, and (x, y ) to denote the scalar product of vectors x and y in Rs. For m=(m1,…, ms...

A GC^1 CUBIC INTERPOLATION ON A SPACE MESH
《Chinese Science Bulletin》1991年第20期1755-1755,共1页施锡泉 王天军 
We call the two surfaces the geometric continual or visual continual and denote them by GC^1 if they are of positional continuity and tangent plane continuity at their joints. A set Δ composed of vertices, segments, ...

CONTRACTIONS ON π_k SPACES
《Chinese Science Bulletin》1990年第20期1673-1675,共3页严绍宗 陈晓漫 
Let π_k be a Pontrjagin space, which has a maximal seminegative subspace with k dimensions, and (.,.) be the indefinite inner product on π_k. A linear bounded operator T is called a contraction, if (Tx, Tx)≤(x, x )...

ON A GEOMETRIC INEQUALITY
《Chinese Science Bulletin》1990年第10期798-800,共3页曾振柄 
If C is any convex dosed curve in plane and P, Q, R are any three points which divide the perimeter of C into three equal parts, then the perimeter of the triangle PQR is never less than half of the perimeter of the c...

EXTENSION OF ROUTH'S THEOREM TO SPHERICAL SPACE IN TWO DIMENSIONS
《Chinese Science Bulletin》1990年第7期609-610,共2页左铨如 
Routh discovered that if the sides BC, CA, AB of a plane triangle ABC are divided at points L, M, N in the respective ratios λ:1, μ: 1, γ: 1, the AL, BM, CN intersect to form a triangle A′B′C′ whose area

A MONTE CARLO RENORMALIZATION GROUP STUDY OF ISING MODEL ON 2-DIMENSIONAL RANDOM TRIANGLE LATTICE
《Chinese Science Bulletin》1990年第4期278-282,共5页黄五群 陈天仑 
Project supported by the National Natural Science Foundation of China
Ⅰ. INTRODUCTIONMonte Carlo renormalization group method (MCRG) has become a powerful technical tool for the study of critical behaviour and continuum limit of discrete systems since 1976. The method is therefore wide...

THE PRIMARY EXPERT SYSTEM FOR MAGNETIC FIELD SHAPING-OPTIM
《Chinese Science Bulletin》1990年第1期87-88,共2页韩守真 茅乃丰 李公攀 
The shape of pole surfaces of a magnet is directly related to the field distribution in the effective space of the magnet. An effective way to shape the magnetic field is to make necessary shimming on the pole surface...
