The experiment was conducted to determine the influence of different regulation and control methods of soil moisture, such as plastic film mulching, covering grass under trees, growing grass under trees, irrigating regularly, loosening the soil under trees, on quality of fruit in a non - public nuisance crisp pear garden in the area of old course of yellow river
摘要以45年生酥梨樹為試材，分析測定塑料薄膜覆蓋、樹盤覆草、自然生草、定期灌水、清耕等不同土壤水分管理措施對土壤水分和酥梨品質的影響，結果表明：塑料薄膜覆蓋和樹盤覆草處理中，土壤含水率比較適宜，且變幅較小，有利於果實生長發育和提早著色，提早成熟，產量和品質較好；其它處理中土壤含水率要麼過高，要麼過低，且變幅較大，酥梨的果實品質也比較差。In the study, a new kind inorganic anchoring material was developed, which consisted of special binder and aggregate, the former is made from clinker, blast furnace slag and compound admixture, and the later is superfine sand. effects of the factors such as clinker / slag, binder / sand, solution / binder and constituent of solution on the strength, set - time and contraction of the matrix made from the anchoring material were studied
上述分析研究得出以下結論：新型無機錨固材料具有早強、快硬、高強特點， 10h .抗壓強度可達26 . 5mpa ， 365天強度可達144 . 0mpa ；初凝時間在40min . 3h .之間，且初終凝時間差在15分鐘以內；在保濕條件下具有微膨脹性，膨脹率在0 . 5 %以內。Moisture, the voids and the density of the pavement are expected for many operators in the road department. in order to promote the application of gpr to detect pavement quality as quickly as possible, in this paper some research works were zone. the mainly research results includes the following aspects : ( 1 ) since the dielectric constants of pavement medium have important influence on radar detection results, dielectric properties of pavement layers materials are analyzed for the design of practical gpr system and field application
目前探地雷達在公路上的應用還主要局限於路面結構層厚度的檢測，對路基路面物理力學指標的無損檢測被廣大公路工作者寄予厚望，這一技術的應用還有很多的工作要做，為了使其早日應用於實際，實現探地雷達對路面含水量、空隙率和壓實度的快速無損檢測，本文具體做了以下的一些工作： （ 1 ）鑒于介電常數對探地雷達檢測的重要影響，對路面結構材料的介電特性進行深入分析，為路用探地雷達的實際應用測量提供理論依據。Among those methods, the vacuum metalizing method has been generally used at the early stage of cellular phone production, but has scarcely used at present due to the problems that the productivity is low, because of low productivity, high cost and poor adhesion of metal film with substrate
在這些方法中，真空金屬鍍方法曾普遍使用於早期的蜂窩電話生產中，但是目前罕見使用，由於生產效率低下，成本高，金屬鍍膜與基底材料的粘附力差。分享友人
