先以漆和瓦灰按脱胎工艺技法在木板上上漆打底、磨制光滑，然后用调好的色漆在底板上层层描绘出各种纹样，利用上漆的厚薄不均使画面产生富于变化的明暗调子，从而具有立体感。在作画的过程中，为了更好的表现物体，还根据画面内容的需要，采用宝石、螺钿、蛋壳、金、银、锡等材料进行镶嵌，使画面层次更加丰富。最后经打磨并罩上透明漆用细瓦灰与生油推光，正因为&磨&体现了福州漆画的独特工艺故称为&磨漆画&。

Aiming at a class of complex electromechanical systems, such as 4-high or multi-high cold mills and continual mills, we firstly construct mathematical models of every subsystems by means of structural principle modeling method; nextly, get the overall mathematical model of electromechanical drive system by joining together these subsystems'models according to coupling variables and parameters; we finally simplify the overall model according to time-scale principle which can retain main eigenvalues and significant state variables, and obtain a practical mathematical model of complex electromechanical system. By simulating the CM04 temper mill's model constructed by above-mentioned method, we test and verify that the modeling method is effective and practical. The study analyzes and researches the electromechanical coupling facts and acting laws existing in complex electromechanical system.

In-house design, materials peachwood dark and light contrast to the use of interior style, the harmonization of all the more.

在内部设计上，深色桃木材质的采用和明暗对比的内饰风格，显得更加的协调统一。

The total phases are also seen to differ in color and darkness . Those effects are due to changes in cloud cover and dust content in the atmosphere reddening and refracting sunlight into Earth's shadow.

同时，月球的相位在颜色和明暗上似乎也不同，这是因为大气中的云和灰尘向地球的阴影中折射了日光染红了月面。

The external morphology and microstructure of the compound eye under light and dark adaptation of the dominant predatory enemies Solenopsis invicta Buren in agriculture ecosystems and Public safety were investigated by means of scanning electron microdcope and histological method.

In the suboesophageal ganglion, 5-HT/TPH-like immunoreactive neurons (ca.15) mainly distributed in the lateral and ventro-lateral area, with processes projecting into the suboesophageal ganglion neuropil.

结果表明，5-HT作为经典的神经递质在昆虫的视觉信息处理过程中发挥着重要的调节作用，且主要通过远距离的广域神经调节模式来控制昆虫的昼夜节律行为，并在特定区域和GABA协同起作用；昆虫视觉系统中5-HT的含量还可能与其明暗适应的生理调节方式密切相关。

By the mutual action of its structure and of the laws of light, perspective is produced, which integrates every mass of objects, of what character soever, into a well colored and shaded globe, so that where the particular objects are mean and unaffecting, the landscape which they compose, is round and symmetrical.

眼睛的结构与光学的法则互动，产生出所谓的&透视&，因此任何一组物体，不管它是何种东西，在我们看来都觉得色彩清晰，明暗层次鲜明，井然有序，整体就似乎是一个球；个别的物体或许形态拙劣，了无生趣，但一经组合，就变得对称而完满了。
