查询词典 IN

False.译者:原文: The Boolean has_key and the in and not in operators are Boolean, returning True if a dictionary has that key and False otherwise.

修改为：对布尔类型的方法has_key和in 或 not in 操作符而言，如果字典中有该键，执行has_key方法、in或not in操作符会返回真，否则返回假。

The burner to produce the test flame shall consist of a tube that is at least 35 mm (1.38 in) long and has a bore of 0.4 to 0.6 mm (0.016 to 0.024 in) and that has an outer diameter not exceeding 0.9 mm (0.035 in).

In this study, the expression and function of FGF-13 in developmental follicles and skin during embryonic development,normal vibrissa follilce stem cells and wound follicles in vitro were obserbed,so as to illuminate the possible role of FGF-13 in the skin follicles during embryonic development and damage healing and provide the experimental base for further studying the characteristic and mechanism of the role of FGF-13 in skin.

采用免疫组织化学(Immunohistochemistry，IHC)、免疫细胞化学(Immunocytochemistry， ICC)和原位杂交(in situ hybridization，ISH)技术及体外大鼠触须毛囊的器官培养，研究了三种不同的生物学过程中FGF-13在皮肤毛囊中的表达及作用。

First,the interaction between bipyridyl and In was investigated by the methods of electrochemistry,UV spectra and difference UV spectra.Then the interaction between In and DNA was investigated by the methods of electrochemistry.At last the electrochemistry behavior of interaction between In complex and DNA was studied.

本文选用联吡啶为配体，首先研究了In与联吡啶相互作用的电化学及紫外光谱性质，又对In与DNA的相互作用进行了初步研究，最后进一步研究了联吡啶In配合物与DNA作用的电化学行为。

To elucidate the molecular mechanisms underlying the neural plasticity after CNS injury, the gene expression profile in the rat hippocampus following perforant path transections was explored by several methods including custom differential screening, custom cDNA array and cDNA microarray. Of 2300 cDNA clones from low-abundance rat brain cDNA bank, 6 were identified as differentially expressed genes/ESTs in the hippocampus 35 days after lesion, in which none was confirmed by Northern blot. Of 8000 cDNA elements, custom cDNA array identified 47 as differentially expressed genes/ESTs with above 3-fold changes in the hippocampus 35 days after lesion, in which 25 were up-regulated and 22 down-regulated.
