光源

Photosensitivity may be defined as sensitivity of the skin to a light source.

感光可以被定义为敏感性皮肤光源。

Many contemporary marine invertebrates still employ the strategy for phototaxis.

现在海洋无脊椎动物仍然利用这种方法寻找光源。

It involves exposing the skin to a narrow-band UVB light source, which can be done in a doctor's office or using home phototherapy units.

它涉及的皮肤暴露窄谱中波紫外线光源，它可以做在医生的办公室或家里使用光疗单位。

Characterizing plant phototropism, the algorithm looks the feasible region of integer programming as plant growth environment, and determines the growth probability on different growth points according to the changes of the object function.

该算法从植物的向光性特点出发，将整数规划的可行域作为植物的生长环境，根据各可行解目标函数的变化情况确定植物的生长信息，进而模拟出向光源迅速生长的植物生长动力学模型。

Second-generation phototypesetter: A computer aided phototypesetting system using flash tube as the light source and a rotating film matrix for exposing the film or paper.

第二代照排机：电脑辅助的照相排字系统。它用闪光管作光源，把旋转中的菲林字母板上的字体影排队于菲林或相纸上。

The ASM fiber laser generates 1.8 picosecond pulses with 14 mW average power at 1 GHz repetition rate.

此系统的第一级光源为一功率为14 mW、脉冲宽度为 1.8 ps、重复率为 1 GHz 的脉冲序列。

In conclusion, we find that the speed of light in a vacuum has a constant value regardless of the movement of the observer (our observations from the moving Earth), or the movement of the source of light (our observations of light emitted from the moving pion).

在这个结论中，我们发现真空中的光速有着恒定值，不管观察者的如何运动（我们的观察是在运动的地球上），也不管光源如何运动（我们观察的光由运动的介子发出）。

These integrated solutions deliver high quality light without pixilation, closely replicating the beam quality of traditional light sources.

这些集成解决方案能提供高质量的非点阵化照明，光束质量与传统光源相近。

The light source directs rays through a plane convex lens that focuses the light into a parallel beam. The light beam passes through the grid diaphragm, which splits it to produce a second beam of light 90° out of phase.

光源将光线照射到平凸透镜上，透镜将光线聚焦成平行光束，光束穿过光栅膜片，光栅将光束分离出第二根90度异相光束。

Experiment with He-Ne laser and white light for interference, focus on the fringes of the changes and the two plane mirror and the parallel degree from the relationship.

实验中以He-Ne激光和白光干涉仪为干涉光源，重点讨论条纹的变化与两个平面镜的平行度及距离的关系。

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。
