发现物

Two phylogenetic footprints, 35 bp and 17 bp in length respectively, were found in 5' intron sequence.

在内含子的5'端发现了两个高度保守的序列——进化印记，长度分别为35 bp和17 bp，35 bp的核苷酸片段能与HeLa细胞和鸡胚细胞抽提物中的蛋白结合，可能是一种调节元件。

In the first chapter, a review is provided on the development and present state of liquid crystalline ionomer , blenlds and hybrids composite materials.

检索结果发现在液晶聚合物的末端引入对羟基偶氮苯磺酸离子的主链热致液晶离聚物尚未见报道。

The kinetics of isothermal crystallization has been studied for Na+,Mn2+ and Ca2+ ionomers based on maleic anhydride graft polypropylene by DSC,compared with pure PP and PP g MAH.

采用DSC对马来酸酐接枝聚丙烯及其3种5个离聚物的等温结晶行为进行了研究，发现在相对结晶度2％～90％的范围内符合Avrami方程。

May 11th 2006 | CLARENDON, ARKANSASTHE ivory-billed woodpecker is not large, as birds go. It is about the size of a crow, but flashier. Its claim to fame[1] is that, though it had been thought extinct since 1944, a lone kayaker spotted it about two years ago, flying around among the cypress trees in the Cache River National Wildlife Refuge.

象牙喙啄木鸟与普通的鸟一样，体形不是很大，跟乌鸦差不多，但羽色较亮。1944年以来人们一直以为它已经灭绝，但大约两年前，一个划着小船的独行客在凯奇河国家野生物保护区的柏树林中发现一只啄木鸟正在四处飞翔，因此，这种鸟就出了名。

In the SDBS experiment, no result could indicate that genomic DNA was damaged by SDBS, no matter L. japonicas was exposed to SDBS or DNA was incubated with SDBS. Fig 3, Tab 1, Ref 22

在十二烷基苯磺酸钠污染实验中，不论是作用于鲈鱼个体，还是直接污染其DNA，用所筛选出的6条引物扩增结果未发现对基因组DNA造成损伤，图3表1参22

According to the results of the examination, the stronger the electron-withdrawing protective group of imines, the better the cis-selectivity of the reaction, 68% yield, trans:cis is 99:1 diastereoselectivity could be leaded by Ts-imines (4-methyl-N-methylene-benzenesulfonaides) with a substituent [2,4-(CH3O)2C6H3], Substrate scope investigation revealed that a wide variety of ketenes and imines could react smoothly to afford corresponding,β-lactams.

实验结果表明，亚胺的保护基团吸电子能力越强，越有利于顺式产物的生成。对甲苯磺酰基保护的取代基为2，4-二甲氧苯基的亚胺参与的该反应可得到68%的产率，反式：顺式=99：1的非对映选择性。底物拓展过程中发现Staudinger反应适用于多种不同的亚胺与烯酮。

When a team of locksmiths wrenched open the safes that month, every last piece of the Bactrian gold was there, trussed in the same tissue paper in which the museum staff had wrapped it.

五个月后，研究人员打开堆在同一个地窖中的一组贮物柜，于是又有了一个让人惊讶不已的发现：有2000年历史的象牙雕刻与玻璃器皿。
