趋性

Cis-3-hexen-1-ol, butyl acetate, ethyl butyrate, hexanal, trans-2-Hexen-1-al, propyl propionate that consists of green leaf volatiles and cymene were the most attractive compounds.

顺-3-己烯醇、乙酸丁酯、丁酸乙酯、丙酸丙酯及伞花烃等对光肩星天牛具有较强的正趋性反应。

By using "Behavior Style Questionnaire- Short Form" and "Young Child Attention Scale", the main findings are listed as follows: A.Results on the dimensions of temperament indicated that children's characteristics of temperament show high on rhythmicity, adaptability and intensity of reaction, middle on activity level, withdrawal, persistence and distractibility, low on sensory, and a little negative on quality of mood.

并采用「幼儿气质量表」与「幼儿注意力量表」收集资料，透过SPSS15.0的资料处理与分析，描述性统计、单一样本t考验以及皮尔森积差相关与多元回归分析结果显示：一、受试幼儿在气质各向度的表现特徵是反应强度大、情绪本质稍偏负向及反应阈偏低现象，其他，则活动量中等但稍偏低、规律性高、适应性高、面对新事物的反应倾向趋性，且坚持性、分神度均有偏高倾向。

It is achieved by protoplasmic streaming, extrusion of cell substances, or by locomotory appendages, such as flagella and undulipodia.

趋性的产生基于原生质流、细胞物质的溢出、或者通过生物附器的运动，例如：鞭毛和波动足。

Gravid An. sinensis demonstrated significant negative taxis towards bacteria A4 and Aeromonas sp., as well as slight taxis to Enterobacter sp., implying that the three bacteria were not the dietary preference for An. sinensis. However, in light of the possibility of their stable colonization into mosquito's guts, these strains may serve as the host cells of larvicide genes and transgenic anopheline antimalarial genes.

中华按蚊产卵时对A4菌和气单胞菌具有明显的负趋性，而对肠杆菌仅具有微弱的趋向性，推测这3种细菌可能不是中华按蚊食物的优先选择，但具有在蚊中肠内较为稳定存活的可能性，因此更适合于作为蚊幼生物杀虫基因的寄主细胞和仿转基因按蚊抗疟基因的寄主细胞被应用。

E: One possible technique is to utilize "taxis" of microorganisms, an intrinsic locomotor response

C： 一种可能技术利用微生物的趋性，一种身体的移动反应

E: One possible technique is to utilize "taxis" of microorganisms, an intrinsic locomotor response toward or away from

C： 一种可能技术利用微生物的趋性，利用身体的移动靠近或远离Q：为何移动？

We developed new spectroscopic methods to create stable odorant gradients in which odor concentrations were experimentally measured.

结果，他们证实，果蝇幼虫的大脑不但能利用立体线索来定位气味，而且还能指导它们的化学趋性。

Phototaxis A TAXIS in response to light.

趋光性：指对光刺激所产生的趋性反应。

Accordingly, we suggested that the neurotropism of human enterovirus is not governed by viral IRES. Additionally, we investigated La, PTB, PCBP2, and Unr, the known ITAFs of poliovirus, on their roles in interacting with EV71 IRES.

结果发现虽然不同病毒其IRES活性也有所不同，但是在神经细胞与非神经细胞间却没有差异，表示肠病毒的IRES活性不受神经系统与否所影响，因此肠病毒的神经趋性是由IRES以外的因素所造成。

Taxes are also paratonic movements.

趋性亦属感性运动。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
