AIRSS calls for reducing the ice multiplier values by one if the concentration of ice exceeds 0.6 and 30% of that ice is ridged (Transport Canada 1998), indicating the occurrence of ice pressure.

如果冰的浓度超过了0.6，30%的冰形成冰脊（加拿大运输部，1998），这意味着冰压力的出现时，AIRSS要求把冰的乘数值减少一。

In very thin mirror polishing technology, a non hard support points polishing method and a computer closeed loop controled separate support polishing method have been developed, and successfully polished a very thin hexagonal plano mirror with 1100m in diagonal and 25mm in thickness, and a very thin meniscus spherical mirror with 1035mm in diameter and 26mm in thickness.

超薄镜面磨制技术试验研究了"无硬点支撑的磨制技术"和"计算机闭环控制的分离支撑点的磨制技术"，并试验磨制了一块对角径1100毫米，厚25毫米的超薄六角形平面镜，和一块直径1035毫米，厚26毫米的超薄球面镜。

1 Background of it: Handmade Cloth Shoe of Many-layer Tread of "Tugada Brand" was made of tread from cotton culico of 30 or so layers through handwork stitch, of upper from high grade cloth like "Canonicals Wool", and "Spring Breese Wool" after 10 or more working procedures of shoe-making. The most notable feature for this kind of shoes is air free and sweat absorbable. Wearing them may facilitate the stretch and adaptability of feet to their surroundings. Therefore, care to one's foot may be realized. Whole production procedure for this shoe is free from any chemical substance, and it belongs to one thoroughly natural production manner. These shoes have combined the skill, comfortable, and air free to one purpose of health care with character of cold-proof in winter and heat-insulation in summer.

项目背景："土疙瘩"牌手工千层底手工布鞋由30余层纯棉白布合成袼褙，经手工麻绳衲制，鞋帮是由"礼服呢"、"春风呢"等高档布料经过十余道工序精细雕琢而成，手工布鞋最显著的特点就是透气、吸汗性强，能够增强足部对周围的伸展性和适应性，实现对人体足部的保养，整个制作过程不含任何化学成分，是一种纯自然的制作流程，一种融工艺性、舒适性、透气性养身保健为一体，冬季御寒、夏季隔热。
