查询词典 attenuated

First, a series of liquid crystal polymers with different amounts of cholesterol mesogens and ferroelectric property are synthesized in this research. The structures of the compound synthesized are confirmed by IR and 1H-NMR spectroscopy. The thermal properties are characterized by DSC, POM. In this research, the 3-D molecular arrangement of molecular were measured by Polarization Modulation-Attenuated Total Reflection-Flourier Transform Infrared spectroscopy (PM-ATR-FTIR).

中文摘要本研究分成两个部分，第一部分为合成铁电性液晶及胆固醇液晶，以FTIR及 1H-NMR来鉴定化合物的结构，并以POM观察其液晶特有的光学纹路，用DSC来观察矽氧烷类液晶的液晶相的热转移温度并利用偏光-衰减全反射-傅立叶转换红外线光谱仪(Polarization Modulation-Attenuated Total Reflection – Flourier Transform Infrared)来探讨矽氧烷类液晶分子的三度空间排列。

In order to compare the homology of the gene encoding VP2 between MDPV-Q and MDPV which was registered in the GenBank, also in order to find out changes of the VP2 gene and the immuno-genicity between the wild-strain MDPV-Q and the attenuated strain MDPV-26 which derived by continued passage of virulent wild-type in muscovy duck embryo, a pair of primer (LHMP7/LHMP8) was designed. The upper one LHMP7 and the lower one LHMP8 corresponded to the MDPV-specific nucleotides sequence 2885-2900 and 4618-4604 respectively, according to the MDPV nucleotide sequence databases. The length of the sequence embraced by the primers was 1734bp.

Some serum samples from ducks immunized with attenuated DPV were assayed with the ELISA kit, and the antibodies were detected first on day 6 or day 9 post-immunization in ducks vaccinated subcutaneously, orally or nasally, and still detectable on day 60 PI.

应用该试剂盒对皮下注射、口服和滴鼻免疫DPV弱毒的20日龄樱桃谷鸭血液中抗DPV特异性IgG抗体效价进行了测定，皮下免疫鸭于第6d，口服和滴鼻免疫鸭于第9d可在血清中检测到DPV特异性抗体，且至第60d时依然可检测到高效价抗体。

The results indicate that the amount of chloride ion sedimentation is attenuated by the natural logarithm function of distance from external surface of the sample,and the corresponding attenuation rate is changed greatly by the ratio of water to cement and mineral admixture such as slag. Chloride ion is mainly deposited in surface zone under dry-wet cycle condition.
