波利亚数学教育理论的现代启示 |
| 2. | I dont want it , polya ; tell them to take it away , said natasha
“用不着了，波利娅，吩咐他们把它拿走吧。 ” |
| 3. | Sv40 polya signal and two loxp sites was added consecutively after the termination codon taa , and then a gfp gene was inserted between the two loxp sites
在三个终止密码子taa之后，连上sv40polya 。 sv40polya之后，又连上两个loxp位点。在两个loxp位点，插入标记基因gfp 。 |
| 4. | A late baculoviral transcription initiation motif ataag was found 65 nt upstream of the putative translational start site and a polyadenylation signal aataaa was identified 14 nt downstream of the taa stop codon
在其起始密码子上游- 65nt发现杆状病毒晚期启动子转录起始信号ataag ，在其终止密码子下游- 14nt发现polya加尾信号aataaa 。 |
| 5. | Demonstration research 1 interprets that under me normal demand there are no distinct diversity between the grade of the experiment class and the contrast class , but the grade of the experiment class is only a little better than that of the contrast class . but the grade of the experiment class where g . polya inspiring method was used is the best
实证研究一，说明了在常规要求下实验班与对比班数学成绩没有显著性差异，只是实验班比对比班成绩稍好一些，而含波利亚启发法的实验班成绩最好；实验班的学生成绩差距缩小，仅含分层教学的实验班的效果最好。 |
| 6. | The students " grade of the experiment class reduced gap . the effect of layer division teaching ' s experiment class is the best . demonstration research 2 shows that there are distinct differences in the ability of solving the synthetical problems ( for the first time ) between the experiment class where g . polya inspiring memod was used and the class where g . polya inspiring method was not used
在访谈调查二中，优等生和非优等生经过实验后，他们在数学学习动机、习惯和兴趣等方面都向积极方面变化，含波利亚启发法实验的学生更喜欢数学、更主动学习数学、充满自信、数学创造能力增强；含分层教学性实验的学生自主学习意识最强。 |
| 7. | Badh cdna ( 1901bp ) included a 66 bp 5 " utr , a 329 bp 3 " utr and a 1506 bp orf encoding a 501 - ammo - acid polypeptide which showed 88 % sequence identity to badh from spinach , sugar beet and atriplex hortensis respectively . the deduced amino acid sequence included a decapeptide sequence " vtlelggksp " , which is highly conserved among general aldehyde dehydrogenases ( aldh ) , and a cysteine residue
Badhcdna全长1901bp ， 5端非编码区66bp ， 3端非编码区329bp ，含有2个可能的加polya信号： aataa ，开放阅读框架1506bp ，编码一个由501个氨基酸构成的多肽，与菠菜、甜菜、山菠菜badh的氨基酸序列同源性均为88 ，其中有醛脱氢酶的保守序列vtlelggksp和半胱氨酸残基。 |
