趋光性

For instance, phototaxis would be movement in response to light.

例如，趋光性将运动的反应轻。

Chloroplasts also show phototaxis,and take up specific orientations in relation to the direction of the incident light.

叶绿体也显示出趋光性，依据入射光的方向来调节其特殊方位。

In the region of light intensity between 1—400 lx,phototaxis of the beetle increased with light intensity.

在光照为1～400 lx范围内，趋光性随光照强度提高而增强。

Phototaxis A TAXIS in response to light.

趋光性：指对光刺激所产生的趋性反应。

Understanding phototaxis thus unravels the first steps of eye evolution.

因此，了解了趋光性也就揭示了眼睛进化的第一个阶段。

A relative remarkable phototaxis of the beetle has been proved under the conditions of laboratory.

叶辉纵坑切梢小蠹有明显的趋光性。

For disaster behavioral psychology shows that the public at the scene of the fire escape when the performance of the "Biological phototaxis" and "sheep mentality" is the main reason for the failure to escape; the fire evacuation routes designed to maintain the smooth flow of the premise, the solution to the fire lighting and visual guidance problem, we solved the major problem of fire escape.

为灾行为心理学表明，公众在火灾现场逃生时所表现的＂生物趋光性"和"从众心理是导致逃生失败的主要原因；在消防疏散通道设计合理、保持畅通的前提下，解决了火灾中的照明及视觉引导问题，就解决了火灾逃生的主要问题。

It is explained that all the plants have the phototaxis. It';s especially obvious for the poplars. Because of the different positions and conditions, some saplings are tall, while some are short.

树林的整体走向是四周低，中间高，北边高，南边低，有人解释说：这是因为植物都有趋光性，杨树尤其明显，由于位置不同、条件不同，自然小树有高，有矮。

"For a long time nobody knew how the animals do phototaxis with their simple eyes and nervous system," explains Detlev Arendt, whose team carried out the research at EMBL.

阿伦特解释说：很久以来都没有人知道这些动物简单的眼睛结构和神经系统是如何产生趋光性的。

The results showed that there were two generations in one year, and there were 6~8 instars in duration of larvae's development. Larvae over-winters under bark or in base of tree. Adult were phototaxis and active on night.

结果表明：该虫在吴旗县一年发生2代，以幼虫在粗皮下或树基越冬，幼虫6~8龄，具吐丝下垂习性，在阴坡立木被害重于阳坡，成虫夜间活动，有趋光性。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
