LA1060. he masker frequency was then increased to 1060 Hz, and the two threshold measurements repeated with all other parameters remaining the same.

然后，将遮蔽频率增加到1060赫兹，当所有变数维持相同的状态下重新测量其遮蔽门槛。

Both masker and probe were ramped on and off to avoid spectral splatter.

心理物理测量在依据以下情况实行：（1）频率1000赫兹、反应时间20毫秒的探测音其声音位准高于静音临界15分贝(如15分贝的感觉层次)，（2）将反应时间300毫秒的遮蔽音，其位准调整到可听闻试验中75%的探测音(如探测音仍然在其"遮蔽门槛"内)，遮蔽音和探测音两者断断续续地跳动，以避免频谱散射。3。

The software includes two modules. One is to evaluate and manage how smoke bomb can shield the thermal images, which can be used as the guide in the development and improvement of thermal smoke bomb. The other is to process the data of thermal images under smoke-screen to locate target in the shortest time and improve the quality of the target thermal images, which can be used as the reference to further design for development and improvement of thermal image.

The results show that not only the porosity does greatly affect the windbreak, but also the tree distance does. The distance is not beyond 1.3 to avoid air leak. The tree belt with porosity 31% has bigger windbreak range and better characteristics for abating wind erosion. The tight nubby tree belt is advised to restrain the particles adhering on the leaves refloating for large velocity deficit in trees.

结果表明：不仅林冠疏透度对防护林带的遮蔽防风有明显影响，而且树木间的株距对林带整体的遮蔽效果也有比较显著的影响，为避免穿流风对遮蔽效应的影响，林带宽距比不宜超过1.3；疏透度为31%的网状林带的有效防护范围大，防风效果好而且水土保持性强；紧密型块状林带，林后速度衰减幅度大，可抑制附着在叶片上粉尘的再次扬尘。

It is in this strong sense of destructive tragedy that Shen's "lyric poetry of countryside" shows the beauty of a deiform land which is rooted in his motherland and is shaded by modem industrial civilization, i.

The narrative subject is the urban individual repetition of the grand narrating under the control of the new ideology, which has the function to de-construct and overthrow the legality of the latter. The narrative object of the Dushi Minjian pays attention to the powerless public whom were concealed by the false promises of the mainstream social modernization, thereby the original Tightness and the humanism thought could be found. The narrative form is not a kind of pure narrating of Minjian area, but concentrated on the aesthetic space, thus self-speech would harvest its possibility, significance and value consequentially in the multifold narrating among the political discourse, commercial discourse and the intellective discourse.

它具体表现为：在叙事主题上，都市民间的个人叙事是对新意识形态控制下的宏大叙事的重述，并在个人的重述中实现对后者合法性的瓦解和颠覆；在叙事对象上，都市民间叙事关注的是被主流社会现代化虚伪承诺所遮蔽的弱势的人群，从而表现出知识分子的原始正义和人道主义关怀：在叙事形态上，没有纯然的民间叙事，对民间审美世界的关注，必将使其在政治话语、商业话语和知识分子话语等多重叙事中获得了自我言说的可能、意义与价值。

In order to draw a photorealistic surface, Bidirectional Texture Functions, a 6D texture function which extends Bidirectional Reflectance Distribution Function to include the self-shadowing, self-occlusion and inter-reflection effects, has been mentioned frequently in recent years. Its main drawback is its massive data size. To solve this, Spatial Bidirectional Reflectance Function techniques compress BTFs into reflectance model parameters. However, SBRDF cannot producethe self-shadowing and self-occlusion effects in real-world surface geometry. This work is aimed to this drawback. I find how self-shadowing and self-occlusion affect the surface by additional physical-based analysis. And I rely on two physical phenomena to divide self-shadowing and self-occlusion into two independent effects. First, self-shadowing is view independent. Second, self-occlusion is independent of lighting direction changes. After these analyses, I use SBRDF and additional self-shadowing and self-occlusion I found to render a photorealistic surface as non-compressed BTFs doing.

为了把物体表面呈现的更真实，六维函数BTFs ( Bidirectional Texture Functions)目前已经被使用的相当频繁，但BTFs的资料量实在太大而没办法直接使用，为了解决资料庞大的问题，传统的SBRDF以逼近光反射模型参数，来达到资料压缩的效果，但是SBRDF对於表面的凹凸所产生的阴影及遮蔽，不能达到逼真的呈现，为了改善这个问题，我们选择从物理方面，找出资料中阴影和遮蔽等属於表面几何的资料并去除，使参数更正确，同时利用两个物理现象去区分阴影及遮蔽为两个互不干涉资料，第一是阴影不会因视角不同而改变，第二是遮蔽不因光线方向不同而改变，经过这些分析，我可以利用SBRDF加上附加的阴影及遮蔽两种独立的效应，来达到彷佛跟未压缩过的BTFs一样的真实绘图。

E. OCB mode LCD elements . Then,we added bi-functional powder and LC E7 in the bulk copolymer of Poly Acrylic Acid and EOPO,then poured the LC solution,and exposed it with 5V voltages under ultraviolet radiation. Finally,we observed the changing phenomena of the planar display of OCB cell with additional external voltage under polarized microscopy . It can be observe obviously the polymer wall in OCB cell when NO.4 LC solution having concentration of 3％ wt . At the same time,the polymer which didn't sheltered by mask will polymerize,then,lead LC into high inclined angle alignment. And it formed discontinuous structure along mask affected LC which surrounded the wall. The results measured by photoelectric instruments showed the discontinuous structure not only keeps the inner LC structure at twist mode,but also promotes the originated respond-velocity of OCB.

然后利用聚丙烯酸与EOPO之团聚共聚合物，添加双官能基粉体及液晶E7，制备成液晶溶液再注入液晶盒里，放置光罩并给予固定外加5V电压在UV下进行曝光，然后在偏光显微镜下外加电压观察液晶盒的平面显示变化现象，发现四号高分子的液晶溶液在3%时，可以明显观察未被光罩遮蔽的高分子将会聚合形成高分子格子结构，并造成液晶成高倾角排列，顺著光罩形成不连续的结构藉以影响墙周围的液晶，从光电量测结果显示，利用此种不连续结构不仅可将内部液晶结构维持在twist的状态，也成功提升OCB原有的响应速度。
