But because the standard has the bug of illegibility and delay, we sometimes can't exactly tell the level of the educational choice.

但实践的评判标准具有模糊性、滞后性的缺陷，并且实现了的教育总是唯一的，这导致了教育选择水平的高低具有某种程度上的不可判断或不可证性，教育选择主体可以种种理由和借口而推卸自己本应承担的责任。

A female vole showed no difference in any behavior between an unfamiliar and unmated male and an unfamiliar male which had just mated with a no experimentative oestrous female vole. A male vole visited and mated with the unmated females significantly more than the females mated before the experiment.

Methods 160 patients with hypodynamia and vertigo after injected the antibiotics,expand the afferent medicine and other the medicine(expel the medicine with the result that high blood pressure,low blood pressure,low blood sugar but appear the above symptom),were randomly divided into two groups:one of the normal regulations treatment(glucose +the vitaminc+vitamin B6),,the other group use the Watersoluble vitamin,contrast to observe the efficacy of the treatment after a week.

摘 要］目的：探讨用水溶性维生素治疗药源性乏力、眩晕疗效。方法：选择160例注射抗生素、扩血管药及其他药物后出现乏力、眩晕症状的患者(排除药物所致高血压、低血压、低血糖而出现以上症状)。随机分为二组：一组常规治疗(葡萄糖+维生素C+维生素B6)；二组用水溶性维生素治疗，治疗时间为一周，对比观察其疗效。

The average percent value of G C (49.3%) was less than that of A T (50.7%), there was a bias of the content of G, T in the third codon; The number of transition G-A and T-C were 22, 15 respectively, which were higher than that of transition A-G and C-T, the number of tranversion C-A, T-G is 2 respectively, and other tranversion patterns didnt occur; the probability of transition was higher than that of tranversion , Ts/Tv = 9.5-19, there was the highest number of transition in the third codon. The gamma parameter a of the lst,nd and 3rd codon positions were 0.00572,0.01237 and 1.05239 respectively, they showed that there was adifferent substitution rate at different codon position. Frequences of synonymous codon usage were relatively biased. The average rates of synonymous and nonsynonymous substitution were 0.0787, 0.0011 respectively, there was a significant difference between dS and dN (Z = 4.713, p.01), and the low ratio( CD = 0.0284 .3) of dN/dS ratio impled that there were selective constraints against the nonsynonymous sites in cyt-b gene, The distribution of nonsynonymous codon substitution pattern related to Grantharm distance indicated that the purified selection at 2nd codon positions was more intensive than that at 1st codon positions. The phylogenetic trees supported the view of the double origin of Chinese goose, which means that domestic Chinese goose was derived from Anser cygnoides and domestic European goose, and Yili was derived from Anser anser.

碱基含量分析可知，序列的G C含量(49.3％)＜A T含量(50.7％)，密码子第三位点的G、T含量都有较强的偏倚性；序列间G→A和T→C的转换数(22次和15次)高于A→G和C→T的转换数(10次和9次)，C→A、T→G颠换数均为2次，其余颠换模式均未发生；转换数明显高于颠换数，Ts／Tv=9.5～19，密码子第三位点的转换数最高，呈现了相当强烈的转换偏倚性；密码子第一、二和三位点的gamma分布参数α值分别为0.00572、0.01237和1.05239，表明密码子第一位点的替换速率变异最大，第二位点次之，第三位点的替换速率变异相对较小；编码同一氨基酸的同义密码子并非随机使用，表现出一定程度的使用偏倚性；同义替换速率和非同义替换速率分别为0.0787和0.0011，dS与dN值间的差异极显著(Z=4.713，p＜0.01)，而ω=0.0284，明显小于0.3，表明雁属鹅细胞色素b基因序列经历了中度净化选择作用；单步非同义替换(Sing-step nonsymonymous codon substitution，SSNCS)分布模式与Grantharm距离之间的关系说明密码子的三个位点所受的净化选择强度不同；构建的最大简约树与邻接树拓扑结构一致，支持中国家鹅的双起源学说，即除伊犁鹅外的其它中国鹅品种起源于鸿雁，伊犁鹅和欧洲的郎德鹅、莱茵鹅起源于灰雁。
