查询词典 wavelengths

In different wavelengths of ultraviolet light to reach the Earth's surface UVA radiation levels up, it will invasion dermal layer, leading to skin aging, have wrinkles, mottling, and the injured skin is not easy recovery.

Multiple wavelengths characteristics of dayside aurora activities were investigated with these keograms and in reference to all-sky images. It was found that there are three repeatedly appearing aurora activity regions along the dayside aurora oval. They are, Region A around 0900MLT in which aurora moves poleward while its intensity decreasing, and its form changingfrom arc to corona with time; Region B around 1330MLT in which aurora moves equatorward while its intensity increasing, and its form changing from corona to arc in time; Region C around 1330MLT in which aurora expands poleward while its intensity decreasing, and its forma evolving from arc to multiple arcs in time. There is a narrow belt of aurora activity in North-South direction between Regions A and B, which is dominated by weak and red corona aurora.

初步分析发现，沿日侧极光卵不论磁静日还是磁扰日，在三个波段上都同时观测到了四个重复出现的极光活动区，即0900MLT附近的A区、1330MLT的B区和1630MLT的C区以及1200MLT附近的G区。A区内的极光活动由低纬向高纬运动，强度逐渐变弱，形态由较宽的弧状极光向冕状极光演变；B区内的极光活动由高纬向低纬方向运动，形态呈现为冕状极光向较窄的极光弧的演变，极光强度逐渐增强；C区极光活动向高纬方向展宽，强度逐渐变弱，极光由单弧向多重弧演化；而在A与B之间存在一个纬度范围相对较窄的极光活动区G区，该区的极光呈现暗弱的冕状极光。

Of all of these specific wavelengths, the wavelength of 980 nm is absorbed the most by water.

在这些所有特定波长中，980 nm的波长大部分会被水吸收。

The most striking quality of opal is its ability to refract and reflect specific wavelengths of light.

最明显的质量蛋白石是它能够折射和反映特定波长的光。

The experimental results show that the output of two-way signal with wavelengths converted has a good extinction ratio.

Different wavelengths of ultraviolet role in the depth of different skin, the longer the wavelength of its penetrating power of the stronger.

They are involved in phototropism, and in PHOTOPERIODISM, where they are thought to affect phytochrome by transferring light energy from blue to red wavelengths.

它与向光性和光周期有关，一般认为黄素通过把光能从蓝光转移到红光而影响光敏色素。

To properly explore the photoreceptor for the negative phototropism in rice (Oryza sativa L.) root, lights with different wavelengths were applied to investigate the effect of light quality on phototropic response. The negative phototropic bending could be induced prominently by blue/UV light, while not be induced by red and far-red light.
