The tactile directional map is similar to regular directional maps in function. Yet, due to the fact that it requires specified Braille explanation and larger tactile elements, the information density on the tactile directional map is relatively lower. Consequently, a tactile directional map is normally not as delicate and not as comprehensive as a regular directional map. The purpose of this study is to examine the appropriate size of various elements on the tactile directional map and to develop a set of design principles in order to create one that better meets the need. It first explores the way the visually impaired use the tactile directional map and inquires about their views and suggestions.

一般导引地图上有指示性图示，超越文字的藩篱，能让大多数人能理解，且可简化版面的设计；然而触觉地图虽与一般地图相类似，但增加了点字说明和一些触觉元素，可是却鲜少有图像，这是由於点字和一些触觉元素的特性使然，因而使得触觉导引地图上的资讯密度相对较低，造成触觉导引地图缺乏像明眼人导引地图一样地设计完善，也没解释这麽清楚、更缺少图像化的设计，若是维持和一般导引地图相同的资讯密度，则触摸导引地图的面积会过大，超出了一般人手部可触及的范围，造成了视障者触读的不便，这都会使得资讯残缺及迷失，甚而产生一些不可知的危险状况。

Both design patterns, which name and describe design elements, and the closely related notion of design rules, which offer imperative advice in specific design situations, are usually articulated at a level of abstraction above the implementation details of the game, dealing purely with relationships between visual elements, game rules, and player interaction.

对设计原始的命名和描述的设计模式以及与设计规则密切相关的理念（这种设计原则在设计中遇到特殊情况时会发出的强制忠告），都经常与的游戏操作细节上的抽象程度、可视元素之间的关系的纯形式处理，游戏规则和玩家家的互动等相关联。

It was anticipated that more than 50% of ash and the hazardous elements As, Co, Cr, Cu, Hg, Mn and more than 30% of sulfur in most coal would be routinely removed by physical coal cleaning procedures, however, the removability of other hazardous elements Ba, Be, Cd, Cl, Mo, Ni, P, Pb, Sb, Se, Th, U, V and Zn displayed relatively lower or a wide range of variation.

结果表明：物理洗选不但能降低煤中的灰分与硫分，还能不同程度地脱除煤中有害微量元素；预测在物理洗选过程中，多数煤中灰分以及有害微量元素As、Co、Cu、Cr、Hg与Mn的脱除率大于50％，硫分的脱除率大于30％，其它有害微量元素Ba、Be、Cd、Cl、Mo、Ni、P、Pb、Sb、Se、Th、U、V与Zn的脱除率相对较低或表现出一个宽的变化范围。

Also, when adding or removing elements, there is no need to make any change to other elements.

另外，在添加或删除的元素，则没有必要作任何更改的其他因素。

Determined by the specific geological background of Longhetun, the characteristics of the soil resources show abundant calcium and leaning to alkaline. Monomial indexes to evaluate the revisal coefficient of soil adapted to karst mountains areas were screened out combined with the function of karst dynamics system and analysis of characters of each factor about fertility in soil. Predigestion model to soil revisal coefficient monomial assessment was established by successful importation of the content of nutrition elements in plant body, latent efficient elements in soil and available thickness of soil in the cranny of epikarst according to the characters that three carriers of soil, soil water and karst water supply nutrition to plants and two layers of foundation consist of surface soil and soil in epikarst cranny, and several types of soil revisal coefficient and weather-soil productive potentiality were calculated, the results show that the soil revisal coefficient was even more practical after modification than before, which make up of innovation of this study.

龙何屯特殊的地质背景条件决定了耕地土壤资源的富钙偏碱的特点，结合岩溶动力系统的作用，系统分析土壤中各肥力因子的特点，筛选出适宜岩溶石山区特点的土壤订正系数评价单项指标，针对研究区存在土壤、土壤水、岩溶水三种载体提供植物营养和表层土、土下表层岩溶带裂隙土两层空间基质的特点，成功引入植物体内营养元素含量、土壤元素隐性有效态含量及土下表层岩溶带裂隙土有效厚度等新参数指标，探讨建立了土壤订正系数单项指标评价简化模型，计算出龙何屯各耕地类型土壤订正系数和气候-土地生产潜力，结果显示修正后的土壤订正系数比修正前更符合实际，成为本研究的创新点。
