光

I normally use quite a lot of light sources; I place them so I can highlight details of the scene. In this image I have used 13 lights: 4 omni lights as ambient lighting, 2 to highlight the form of the engine, 3 spotlights to highlight the back of the engine, 3 highlight to stress the specular and the greasy effect on the shell, a spotlight behind the snail neck for the sub surface scattering, in addition to the sun with area shade and the sky with a HDRI with an atmosphere similar to the photograph of the road for the global lighting I have used a surface with an asphalt texture for the floor and the yellow lines only to be reflected on the engine and to add some radiosity to the snail body and shine.

通常我使用很多的光源，我到处放置它们，这样我才能照到足够多的细节，在这幅图里我使用了13盏灯，4 盏点光源作为环境光，2盏来照亮引擎的形状，三盏聚光灯用来照亮引擎的背面，三盏来强调蜗牛壳的高光及油腻的感觉，有一盏蜗牛脖子背后的灯光来表现3S半透明效果，另外还有一盏太阳光来获得各个区域的阴影，以及一个赋予了HDRI贴图的sky，来作为全局光，我使用了一种沥青材质作为地面材质，并让引擎能反射地面上的黄色带子，并为蜗牛身体与光射线增加了一些radiosity，以取得得与背景类似的灯光环境。

Shading experiments were designed according to low light intensity problem caused by intercropping system of peanut with maize or wheat et al. Fenghua1 and Fenghua2 were adopted in the experiment of four light intensity levels (CK in which the plants were grown under natural light, 27% shading, 43% shading and 77% shading), which carried out at three growth stage using black sunshade net. And the three stages were seedling phase, pod-setting phase and pod-maturing phase. The aim of this study was to investigate the effects of low light on the photosynthetic characteristics, luminous energy distribute of PSⅡ, RuBPCase activitiy, plant morphogenesis, dry matter production, pod yield and quality of peanut at different stages, defined the relationship between dry matter accumulation and PAR, relationship of efficiency for solar energy utilization and PAR, and then set up the ...dry matter production and yield formation model on the basis of the experimental data.

针对花生与玉米、小麦等作物间作、套种造成遮光问题，选用大花生品种丰花1号和小花生品种丰花2号做为供试材料，在花生苗期、结荚期和饱果期分别用不同透光率的遮阳网进行遮光处理模拟弱光条件，设置自然光、遮光27%、遮光43%和遮光77%四种光强水平，研究了光强处理对花生光合特性、光系统Ⅱ光能分配、RuBPCase活性、植株形态建成、物质生产和产量以及品质的影响，明确了不同时期干物质积累及光能利用率与光合有效辐射的关系，以此为基础采用2种方法建立了花生干物质生产动态模型和花生产量形成模拟模型，并对各模型的模拟精度进行了比较。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
