  vector
We give explicit systems of generators of the algebras of invariant polynomials in arbitrary many vector variables for the classical reflection groups (including the dihedral groups).
      
The least upper bound for the degrees of elements in a system of generators turns out to be independent of the number of vector variables.
      
(HereM3 denotes the vector space of 3×3 matrices over k andp>amp;gt;3.) The method of proof involves an induction, and is potentially of wide applicability.
      
A basis is calledmonomial if each of its elements is the result of applying to a (fixed) highest weight vector a monomial in the Chevalley basis elementsYα, α a simple root, in the opposite Borel subalgebra.
      
The proof is based on a variant of Moser's method using time-dependent vector fields.

The size of sacral biatus was measured,the mean width of the base being 18.22mm,the average length between the apex and the base 26.7 mm,the A-P diameter of the canal at the level of apex 5.45mm.The apex was most common- ly located at the level of S_4 or S_5. Examination of articular surface of upper articular process showed that they inclined obliquely in most cases,but could also be coronal or sagittal.Both arti- cular surfaces were symmetrical in 65%,asymmetrical in 21.7%,markedly asym- metrical in 13.3%. The articular surface was extending from upper 2-3(1/2)segments,they were found symmetrical in 86.7%, asymmetrical in 13.3%. In the gross specimens,the curve of the sacrum was also studied,straight. superiorly and flexed inferiorly:17.2%,gently flexed:54%,markedly flexed:11.8%, flat and straight:11%,hyperextended superiorly and flexed inferiorly:6%.In the X-ray film series,“horizontal sacrum”was found in 4.5%. The spinous process of the sacrum remained rudimentary,leaving only the tubercle.Its number was studied. 2 cases with marked anomaly were reported.One girl aged 1,with rudi- mentary sacrum,only 2 segments,the coccyx wanting,L_2-L_5 sacralized.A boy aged 6,had V-shaped defect in the sacrum.Both cases presented remarkable clinical disturbances. The clinical significance relating the abnormalities and variations of the sacrum was briefly discussed.

203 adult sacrals (143 males and 60 females)were investigated.The average height of the sacral canal was 66.8 mm.The sagital length of the sacral canal was 14.0 mm and its transverse length 31.0 mm.The sagital length of the outlet of the sacral canal was 5.9 mm.and it was 5.0% less than 2.0 mm. Sacral hiatus might be classified according to the following six types: 1)Triangular(23.0%),2)Sharp and long(19.4%),3)Square(11.3%),4) Rectangular(11.3%),5)Horse-shoe(20.0%),and 6)Irregular(15.0%). The longitudinal and transversal distance between all sacral posterior foramens were measured. Among the 203 sacrals,it was found that the percentage of normal simple promonory(25th vertebra)was quite high(85.7%),simple promontory formed by 2nd sacral vertebra(26th vertebra)was less than 2.5%,whereas double promontories formed by 25th and 24th vertebrae were found to be 11.8%. In general,the lower margin of the auricular surface reached the third sacral vertebra,but in women it was shorter than in men. The sacral lengths were measured as follows: 1)the largest height—108.0 mm. 2)the largest breadth of the upper portion—111.0 mm 3)the middle breadth—85.0 mm. 4)the highest curvature—119.0 mm. 5)the sagital length of the sacral base—31.0 mm. 6)the breadth of the sacral base—50.0 mm. All the sacral indices were counted as follows: 1)the sacral index—102.7. 2)the index of the sacral breadth—76.6. 3)the index of the sacral curvature—110. 2. 4)the index of the sacral curvature-difference—1.85. 5)the index of the sacral base—62.0. The relation between sacral variations and sacral block anesthesia was discussed.

1.作者观察测量了203个国人的骶骨。2.骶管平均高度是66.8毫米;入口横径平均为31.0毫米,状径平均为14.0毫米;出口状径平均为5.9毫米,小于2.0毫米者占5.0%。3.骶裂孔可分为三角形23.0%,尖长形19.4%,方形11.3%,长方形11.3%,马蹄形20.0%,其他15.0%为变异的不规则形。4.在骶骨上测量了上下位骶后孔之间的距离及左右位骶后孔之间的距离。5.就203个国人骶骨岬观察的结果,具有重岬者占11.8%;其中85.7%为正常的单岬;于产科内诊测量骨盆入口直径时,应注意重岬。6.耳状面下缘位于第3骶椎中部以下者,男性占74.0%,女性占66.0%,耳状面下缘位于第3骶椎中部以上者,女性占34.0%,而男性为26.0%,女性的耳状面短于男性的耳状面,由于女性骨盆上所有关节面比较男性短的原故。7.骶骨最大高径平均为108.0毫米;上部最大幅径平均为111.0毫米;中部幅径平均为85.0毫米;最高曲径平均为119.0毫米;骶基状径平均为31.0毫米,幅径平均为50.0毫米。8.骶骨指数平均为102.7,骶幅指数平均为76.6,骶曲指数平均为110...

本文综合分析了十四种金属的电子结构参数和熔点及升华热的实验数据,提出了一个关于金属原子键强度和电子结构的关系的定性看法,认为电子在波空间状态分布的稳定程度决定原子键强度的高低,费密表面附近的状态密度越小,则电子状态分布越稳定,结合强度越高;并指出:晶体最容易沿电子状态分布改变最小的面和方向滑移。
