在第五章，我们研究了两类线性流形S_1={X∈BSR~|‖XY-Z‖=min}和S_2={X∈BSR~|XY=Z，Y_i~TZ_i=Z_i~TY_i，Z_iY_i+Y_i=Z_i，i=1，2，Y，Z∈R~}上矩阵方程A~TXA=B的双对称最小二乘解。

In the ESI+ mode the compound isolated from fraction III/9 showed a pseudo-molecular ion of m/z 261 ([M + 1]+) as well as sodium and potassium adducts with m/z 283 and m/z 299, respectively, thus suggesting a molecular mass of 260 Da.

在 ESI+模式下，从子馏分 III/9中提取出来的化合物分别出现了伪分子离子 m/z 261 ([M + 1]+)和纳钾加合物 m/z 283 and m/z 299，这样就暗示了260 Da 的分子质量。

Bacterial strains were isolated from humus mud by employing the dilution methods. Seven cellulose-degradation Strains marked as B-37, B-35,B-31, B-25, B-17, Z-a, and Z-b were selected according to the hyaloid rings on the medium of carboxymethylcellulose sodium Congo red and their efficacy of decomposing filter paper. Z-b had the strongest ability in decomposing filter paper among the seven strains and 16S rDNA analyzed indecated that it was Stenotroplaomnonas maltophilia owning to 99.8% homology. Comparing clony size of the seven strains in media with different carbohydrates and inorganic salt, we found that the potato extract and inorganic salt which contained CaCl2 0.20, MgSO4 1.25, NaCl5.00,(NH4) SO4 1.30, KH2 PO4 1.35, FeSO47H2O 0.015, Na-EDTA 0.02 were suitable for the bacteria growth.

用稀释法从腐殖泥中分离菌株，根据它们在梭甲基纤维素钠-刚果红培养基上的透明圈直径及对滤纸的崩解能力，获得7株纤维素分解细菌（编号：B-37、B-35、B-31、B-25、B-17、Z-a和Z-b），其中菌株Z-b的纤维素崩解能力最强，分子鉴定结果表明它与Stenotrophomonas maltophilia的16S rDNA序列有99.8%的同源性，初步确定为嗜麦芽窄食单胞菌。

For k≥1, an isometry φ between codes over Zsubscript P(superscript k+1 and codes over Z(subscript P^2) is introduced and used to give a generalization of the Gray map φ: Z(superscript n subscript 4)→F(superscript 2n subscript 2). Furthermore, by means of this isometry, the concept of negacyclic codes is extended to codes over the ring Zsubscript P(superscript k+1. A characterization of these codes in terms of their images under φ is given. It is also shown that the generalized Gray map image of the 1-P(superscript k-cyclic code is a distance-invariant quasi-cyclic code.

文章引入了Z下标 P(上标 k+1码和Z(下标 P^2)码之间的等距同构φ(k≥1)；利用φ把Gray映射φ：Z(上标 n 下标 4)→F(上标 2n 下标 2)推广为φ：；而且利用φ，负循环码概念被推广到Z下标 P(上标 k+1码，得到了1-P(上标 k-循环码；依据等距同构φ，给出了这些码的表示；也证明了1-P(上标 k-循环码在推广的Gray映射下的像是距离不变的准循环码。
