查询词典 duplexes

In order to calculate Melting Temperature in a more reasonable way, we use the SOFM of kohonen neural-networks to extract wild field features from DNA sequence, and a back propagation network is employed to predict Tm of DNA duplexes with these features.

本文以DNA序列的邻近法参数为基础，根据DNA序列热稳定性特点提出了DNA序列的编码方案，并建立了基于特征自组织网络的解链温度的预测模型。

In this article,we report a study on the duplex stability affected by mismatches and insertions.The effects of the chemical nature,the positions,the numbers,and the cooperative behavior of mismatches as well as insertions on the 20-mer and 30-mer duplexes were examined.

在本实验中，我们系统地研究了20-mer和30-mer的杂交双链中错配与插入碱基的化学性质，位置，数目及协同效应对杂交双链稳定性的影响，总结了相关的稳定性趋势；应用温度梯度PCR实验来验证错配双链的不稳定性。

This is in sharp contrast, of course, to the behavior of DNA–DNA duplexes, whose stability decreases dramatically at low ionic strength because of the required counterion shielding of the phosphate backbone.

当然，此现象截然不同与DNA-DNA二聚体的特性。由于后者的稳定性需要磷酸骨架的屏蔽，在低离子强度时，其稳定性将急剧下降。

Objective:To compare the response control and attention of Schizophrenic patients with that of the healthy controls by Integrated Visual and Auditorycontinuous performance test. To quantitate the impairment of cognitive function in patients, and to explore the relationship between cognitive function and the severity of the disorder.

目的：探讨精神分裂症病人在IVA持续操作测试中的反应控制能力、注意力等，并与健康人进行比较，从而量化精神分裂症病人的认知功能损害，并进一步探讨其认知功能与疾病严重程度的关系。

Main effective factors including subcooling degree, mechanical vibration, gas hydrate reformation, environment temperature, noncondensing gas and surfactant are analyzed.

指出过冷度、机械振动、重复生成水合物、环境温度、不凝性气体、添加剂是影响气体水合物生成的主要因素，还对R152a水合物的放冷进行了实验研究。
