When hanging bag , hang bags interval 3 seedling rope , change bags interval 1 day , fertile 250g in each plastic bag with grit , pitch two holes with the needle , sink the bags into the water 挂袋时，每隔三根苗绳挂一段，隔一天换袋一次，每个塑料袋装肥250g ，内掺砂子，用针扎两个孔，沉到水中。
Some years later , when i found that the delightful japanese translator of the later earthsea books , ms masako shimizu , knew mr hayao miyazaki , i asked her to tell him that , if he was still interested in earthsea , i would welcome talking with him about a film 过了几年，当我发现地海后期书籍的可爱日本译者清水真砂子小姐认识宫崎骏先生时，我请她帮我转达宫崎骏，如果他仍旧对地海有兴趣，我很乐意和他谈谈关于这部电影。

Abstract : this paper briefly introduces the components of structures for both moulded sand bag embankment and moulded concrete bag , its construction and processes . it points out that good economic benefit can be realized by applying this process in shallow beach to minimize embankment sinking 文摘:简要介绍模袋砂子堤和模袋砼结构的组成及施工工艺等，指出对浅海滩采用此工艺能减小路堤的工后沉降，可收到较好的经济效益。
The relevant experiments illustrates a . c . power is more suitable for deicing or snow - melting than d . c . silica fume can improve the dispersion of carbon fibers and then reduce the electrical resistivity of carbon fiber cementious composites . at a certain volume content , when the ratio of cement , sand and stone is l : l : 2 ( by weight ) , the properties of the cfrc is the best on the whole . ( 4 ) a self - adaptive fuzzy controller is designed to finish the total control procedure after considering all kinds of factors 大量实验研究发现：采用交流电是碳纤维导电混凝土用于融雪化冰时的最佳电源选择；采用硅灰能较好地提高碳纤维在基体中的分散性，有效降低碳纤维水泥基复合材料的电阻率；并在现有的级配比实验中发现了具有最好综合性能的配比，即在相同的纤维体积含量的情况下，导电混凝土的具有最好综合性能的配比是水泥、砂子、石子的重量比为1 : 1 : 2 。
Baking - free brick was made by using fly ash , sand , cement and other industrial wastes , which makes the cost of material low . furthermore , when it was made , the degree of mechanization is very high , using few workers , production cycle is short , thus the cost was lowered 免烧砖是采用粉煤灰、砂子、石粉、矿渣等工业废渣按一定比例加入水泥振动，强力压制而成，原料来源价格低，加之生产时机械化程度高，用人少，生产周期短，因此成本低，免烧砖的价格比红砖低，装卸时不容易损坏边角，且没有粉尘，卫生条件好，对人体的呼吸道伤害小。
Main working principal is that the bottom scraper with low rotate speed impels materials to form circumfluence in the basin of machine , the impeller of rotor rotating with medium speed can not only add wallop to sand , but also can add shear force to the sand with scraper so that the sand can touch and scrub each other fast ; wind blasting is set to cool the hot sand , remove dust and strip the membrane so that fast speed of regeneration and top - grade used sand can be gained 主要工作原理是低速转动的底刮板推动物料在机盆内形成环流，中速转动的转子叶片既对砂子施以冲击力，又与刮板配合对砂子施以剪切力，使砂粒间快速接触和强烈摩擦，围圈设风带鼓风使热砂沸腾冷却除尘脱膜，从而达到再生速度快，回用砂质量好的目的。
When wind pressure of fan is deficiency or the inner sand layer of double disk is too thick , the tuyere of double disk will jam especially when moisture of sand is too high ; this jam must be treated by manually because the jam of green sand becomes very hard after air - dry and the system can not renew by itself 当鼓风机的风压不足或双盘内砂层过厚，双盘内风口会出现堵塞现象，尤其是砂子水分过高这种堵塞除非人工清理，其系统本身是无法恢复的，因为湿的砂子堵塞进风口干后会非常坚硬。
One new type double backspin rotor type sand mixing machine passes technique appraisal of qingdao tianheng machinery co . , ltd . this machine adopts double rotor configuration researched internationally ; the rotor is installed on different output axis of same reducer , which produces comparative cross cutting speed by using rotors with different speed that makes sands get strong cutting and friction force . therefore , it can reduce clay and quicken sand mixing 一种新型双逆转子式混砂机在青岛天恒机械有限公司通过技术鉴定，该机采用国际首创的双转子结构，其转子安装在同一减速器的不同输出轴上，利用两个轴的不同转速使转子间产生相对交叉剪切速度，使砂子受到的冲剪及搓擦力加强，从而减少粘土团，加快砂子的混合。
Through reiterative study over years by the author , a new principle to express the relation between aggregate particles size and the surface area was proposed , that is the specific granularity , which could solve the problem of lack of correlation of fineness modulus to the specific surface area of the sand 摘要经多年反复研究，发现了集料粒度与表面积关系法则，提出了以“比粒度”表述砂石粒度的新方法，解决了以“细度模数”表述砂子细度的不足之处，即解决了细度模数与不同细度砂子的比表面积没有相关性的问题。
