Objective To clone and characterize a RRas-like gene from Trichomonas vaginalis for studying cellular signal transduction pathways in the organism.

摘要目的克隆和分析阴道毛滴虫RRas同源基因，以探讨其在细胞内信号传导通路中的功能。

As to the high polarity, high boiling point resultant—trimesic acid, the analysis methods of infrared spetrum, gas chromatography-mass spectroscopy, vapour-phase chromatography, acid number titration and so on are seperately used to characterize its property. Infrared spetrum and gas chromatography-mass spectroscopy are used to have a qualitative analysis on the resultant and are compared with the stand diagram. Sulfuric acid-methanol esterification and rapid esterification are used to prepare the trimesic acid trimethyl-ester and have a FID quantitative analysis. So that we make sure the purity of trimesic acid in the resultant and also we have an acid alkali titration on the resultant to get its acid number, in order to verify the purity of trimesic acid in the resultant.

对于高极性、高沸点的固体产物均苯三甲酸，分别采用红外光谱、气质联用、气相色谱、酸值滴定等分析手段进行了表征：利用红外光谱、气质联用的方法进行产物的定性分析，并与在同一仪器、同一条件下做出的标准谱图进行比对；采用硫酸-甲醇酯化法和快速酯化法制备出均苯三甲酸三甲酯，对其进行气相色谱FID定量分析，进而确定固体产物中均苯三甲酸的纯度；用酸碱滴定法确定固体产物的酸值，以对固体产物中均苯三甲酸的纯度进行验证。

The eldest wore the white tie, high waistcoat, and thin-brimmed hat of the regulation curate; the second was the normal undergraduate; the appearance of the third and youngest would hardly have been sufficient to characterize him; there was an uncribbed, uncabined aspect in his eyes and attire, implying that he had hardly as yet found the entrance to his professional groove.

因为队伍里没有男子，所以开始时姑娘们相互对舞着，但是随着收工时间的临近，村子里的男性居民就同其他没事的闲人和过路行人一起聚集到舞场的周围，似乎想争取到一个舞伴。

Aspect, rather than spatial scale, had the largest impact on undercanopy light. In forests with rough topography, utilizing transects that run from the ridge to the valley is more likely to adequately characterize spatial heterogeneity than plots or a few longer transects.

在福山试验林，坡向较空间尺度对林下光照有更大的影响，因此在地形起伏剧烈如福山试验林的地区，利用多条由稜线延伸至溪谷的样线，比少数几条绵延甚长的样线或样区更能充分涵盖空间的异质性。

Especially we completely characterize when two quasi-invariant subspaces are similar or unitarily equivalent.
