In this method cement paste is considered as one ingredient instead of two separate ingredients——cement and water. The function of cement paste in fresh concrete is that a large portion of the paste fills the void space in the mixed fine and coarse aggregates, and only a small portion coats the surface of the aggregate particles. Therefore the required amount of cement paste is predominantly determined by the void space of th...             設計混擬土配合比的方法很多,有繁有簡,繁的需要很多試驗与計算,簡的編成配合此表,祇需按表試配。新的方法还在不断創造,趨向于簡化試驗与計算手續,但又要能切合实际,容易得到符合要求的配合比。早在1948～1949年,作者根据混凝土組成原理,——絕大部分水泥漿是用來填充砂石间空隙,很小部分用來包裹砂石粒面及超潤滑作用——先求得最小砂石混合空隙率,加一常数,就可定出最經济水泥漿量,經过試配,確定最終配合比。1951～1952年,幾处工地試用,当時祇能做出水灰此为0.7坍落度3—7厘米的混凝土。1953～1954年,通过学習苏联混凝土技術,將本法發展到適用於各种要求的混凝土,即灰水比坍落度可任意改变,形成目前較完善的形式,合於工地及試驗室採用。本法在选定灰水比及坍落度後,祇需2—3步即可求出配合此,並算出材料用量;本法計算簡便,祇用兩个簡單的表(表1和表3);本法在進行中有自己校核的作用,計算秤量中如有錯誤容易查出。本法祇需極簡單的設备,易於学習,在大同及大伙房水庫工地祇經一小時的講解,試驗員即会应用。本法通过試配,应用的理論和數据都有正確根据,所以結果能切合实际。希望大家試用研究,提出改進意見,使本法日趨完善,並能逐... 文摘来源          Sweet-potato wilt,a dangerous disease of sweet potatoes,has made itsappearance for more than 10 years in several districts of the south-easternKwangsi and south-western Kwangtung.During recent years it has been found tocause a heavy loss of sweet potato crop in these two provinces. Sweet-potato wilt is a kind of wilt disease which infects the fibrovascular ??bundles of the plant.It begins to infect the vine cuttings and those parts thatare in close contact with the sick-soil.The infected parts first show th...             甘薯瘟是一种具有十余年历史的病害,不仅严重地威胁着广西东南部几县的甘薯生产,同时也严重影响了广东西南部和广西毗鄰的几个县的甘薯生产。甘薯瘟是一种枯萎类型的病害,是侵染維管束的脉管病害,首先侵染插条与土壤接触部位,先呈水漬狀,继而变黑腐爛并向上發展,叶色不正常或呈黄色而萎垂。此时薯藤的不定根根尖脫皮并开始腐爛,最后全株枯死。如在結薯块后才受病,除薯藤显现枯萎現象外,可向薯塊發展而呈褐色条斑,最后变黑腐烂,發出刺鼻臭辣气味。瘟薯的病原初步認为是由细菌和镰刀菌所致。细菌中可分为白色粘滑型,黄色粘滑型,白色干绉型和黄色干绉型;鐮刀菌中包括白色气生菌丝型,白色菌丝基層稍呈紫紅色型,粉紅色菌丝基層呈紫紅色型,无气生菌丝型等。但究以哪类为主导,抑系并發性呢?仍須进一步研究。薯瘟病原的傳播,初步認为有三种方式:带病薯块和薯苗,病土,及昆虫(如小象鼻虫等),其中以前二种較为肯定,后一种則仅属可能,仍有待+于进一步試驗观察。甘薯各品种間确具有不同的抗病性能,如台农三号的抗病性較强而产量最高,又能抗旱,台农46号的抗病性最高,但产量則較低,因而台农三号是最有希望的品种,但在岑溪試驗地,会略有發現蔓割病(可能是薯瘟病原之一),临桂試... 文摘来源          In order to study the changes in vitamin C (ascorbic acid) and sugar content both in developing and in mature pods and seeds of garden peas, three varieties were used in this experiment. They are "large-pod of Canton", a variety mainly used for its large edible pods; "white-flower of Hangchow", mainly used for its fresh seeds; and Alaska, an excellent canning variety. Vitamin C, reducing sugar, and total sugar content of pods and seeds of each variety were analyzed throughout the development and ripening of...             本文用了三个蔬菜用豌豆品种为研究分析的材料。一个是廣州的大莢豌豆,这是以豆莢为主要食用的的品种;又一个是杭州的白花豌豆,这是以新鮮种子为主要食用的品种;第三个是“阿拉斯加”豌豆,这是有名的罐头制造用品种。这些豌豆在杭州气候环境下,都是在4月下旬,5月上旬先后开花。开花后6—8天,开始分析它們的豆莢及种子的維生素丙(抗坏血酸)还元糖及全糖的含量。每隔4—6天分析一次,直到完全成熟为止。本試驗所用的三个品种,在豆莢及种子的發育及成熟过程中,維生素丙的含量都是愈成熟而愈少。在發育的初期,不論莢果或种子,每100克新鮮物重中都可以含有40—60毫克的維生素丙,但到了完全成熟时,僅有5—15毫克了。种子中和莢果中的維生素丙含量的变化,差不多有平行的趋向。而且大莢豌豆(軟莢种)的莢果中的維生素丙含量比种子中的为多;而杭州白花豌豆(硬莢种),則莢果中的比种子中的少。这是符合于这兩个品种的利用方式的。至于全糖或还元糖,也都是愈到成熟愈少。但豆莢中的全糖及还元糖,在發育及成熟过程中,虽然也稍为降低,但沒有象在种子中減低的迅速,而且比种子中的含量为多。随伴着种子中的糖在成熟过程中的迅速減少,淀粉迅速的增加,硬度也因而增加。种子中... 文摘来源   << 更多相关文摘         相关查询: 保钾 保奇性 保水的 保成本 强保 保肥力 环境保 恢保 首保 保载 保收敛 保台湾  对查询结果不满意
