查询词典 backbone

DNA is composed of a backbone made from deoxyribose and phosphate.

DNA是由脱氧核糖组成了脊梁和磷酸盐。

Peptide nucleic acid is a kind of new nucleic acid mimic invented in the early 1990s', in which the deoxyribose phosphate backbone has been replaced by a pseudo-peptide polymer to which the nucleobases are linked. PNA is uncharged, highly stable in chemical and biological environments, and binds complementary DNA and RNA targets with remarkably high affirnity and specificity.

肽核酸是二十世纪九十年代初合成的一种全新的核酸类似物，它以多肽骨架完全替代DNA中的脱氧核糖磷酸二酯键的骨架，呈电中性，具有极高的生物和化学稳定性、极强的核酸结合能力和特异性，在分子生物学的许多方面得到广泛应用。

After experiments, we got some results as the following:1.Induced by semi-conductor laser, solid DNA changes as below: 1the deoxyribose-phosphate backbone vibrations in DNA decreasing, these bands are at 884~890cm~(-1),1112cm~(-1) and 1168cm~(-1). 2 deoxyribose and C-O stretch vibration in d increasing, there are new bands occurring at 1436cm~(-1) and 1072cm~(-1), the intensities of these bands at 1466cm~(-1) and 1030cm~(-1) increase.

通过实验研究，得到如下一些结论： 1、固体DNA经半导体激光器照射后，可以导致以下变化：(1)DNA中脱氧核糖磷酸主链振动减弱，包括在884～890cm~(-1)、1112cm~(-1)和1168cm~(-1)处的谱带；(2)脱氧核糖以及d中CO的伸缩振动增强，在1436cm~(-1)和1072cm~(-1)处出现了新的谱带，在1466cm~(-1)和1030cm~(-1)处的谱带强度增强；(3)各碱基的振动频率和相对强度都发生了很大的变化，碱基中羰基的伸缩振动显著增强，在1650cm~(-1)和1670cm~(-1)处出现了新的谱带，在1710cm~(-1)处的谱带强度显著增强。

We can provide two possible solutions for theintegration:- at IP backbone level, to integrate different districts with different brands, for example: B ticino for the villas district and Shidean D2009 for the tall buildings with apartments district.

我们提供两种可能的兼容方式：-在主干网层面，在一个小区内的不同楼宇安装不同的品牌。例如：在别墅区安装Bticino品牌，在高层楼宇区安装视得安D2009品牌。

Guangdong transport is more developed, there is the Beijing-Guangzhou railway, Guangzhou-Kowloon, Li Zhan, Hiroshige, Mellon and other lines; highways to form a center in Guangzhou, Guangzhou-Shantou, Guangzhou-Zhanjiang, Guangzhou-Meizhou, Kwong Wai, Kwong Lo, Guanghai backbone line transport network; water transport passenger and cargo transportation in the province occupies the most important position, with a large number of ports, including Guangzhou, Zhanjiang and Shantou is the province's maritime center and foreign trade port.

广东运输业较为发达，铁路有京广、广九、黎湛、广茂、梅隆等线；公路形成以广州为中心，广汕、广湛、广梅、广怀、广罗、广海线为主干的交通网；水运在全省客货运输中占有最重要的地位，拥有众多的港口，其中广州、湛江和汕头是全省海运中心和对外贸易港口。
