The use ratio of the available components of chemical fertilizers in china is currently lower than that in foreign nations by 10 % ~ 20 % , and their loss in very great 摘要當前我國化肥有效成分的利用率比國外低10 % ~ 20 % ,其流失非常嚴重。
In the meantime , fracture developing frequency of fuyu oil pay zone is analyzed and calculated by using ratio of vertical wave velocity “ crocodile factor ” method 同時,運用縱波波速的比值“龜裂系數(shù)”方法對扶余油層儲層的裂縫發(fā)育頻率進行了分析、計算。
For the sake of incrasing laboratory manage efficiency and use ratio of computers , this paper introduced several experiences and technologies in daily management of laboratory 針對這些特點,基于提高實驗室的管理效率及計算機的利用率,不斷加強實驗室自動化管理程度的原因,介紹了開放實驗室在實驗教學和實驗室日常管理方面的一些經(jīng)驗和技術(shù)。
To understand and apply the techniques used to prepare year - end financial statements of partnerships and companies which comply with international accounting standards , and to interpret financial statements and the relationships between their elements using ratio analysis 理解并應用根據(jù)國際會計準則準備合伙企業(yè)和公司年末財務報表的相關(guān)技能,運用比率分析法解釋財務報表以及其各項目之間的關(guān)系。
The author gives the general situation of using non - metallic minerals , such as kieselguhr , sepiolite , zeolite and bentonite , as carriers of chemical fertilizers and modifying the fertilizers to become long - acting ones , so as to cause the release of the available constituents of the fertilizers to be in balance with the crop needs , raise the use ratio of these components , and reduce environmental pollution 筆者介紹了用矽藻土、海泡石、沸石、膨潤土等非金屬礦物質(zhì)作化肥載體,將肥料改性成為長效肥,使肥料的有效成分的釋放與作物的需求平衡,以提高有效成分的利用率,同時減輕環(huán)境污染的概況。
Based on the principle of fuzzy , utilizing the comprehensive evaluation model of limit analysis on the development of water resources , the authors selected evaluation factors include irrigation ratio of total land , coefficient of product water , degree of water exploitation , water supply and demand modulus , per capita water supply and ecological water use ratio to analyze 摘要基于模糊數(shù)學理論的區(qū)域水資源開發(fā)利用閾分析方法,選取灌溉率、產(chǎn)水系數(shù)、水資源開發(fā)程度、供需水模數(shù)、人均供水量和生態(tài)用水率7個主要因素作為評價因素,以杭州市區(qū)為例進行具體計算與分析。
By introducing the concept of land equivalent ratio ( ler ) , this paper compares protected land with open land , sets up three indexes to express protected land ' s land use ratio raising and its land increment : protected land equivalent ratio of yield ( plery ) , protected land equivalent ratio of production value ( plerpv ) , protected land equivalent ratio of net income ( plerni ) 引入土地當量比概念,以露地為對比分別從產(chǎn)量、產(chǎn)值、純收益三個方面建立了表達保護地土地利用率提高和保護地土地增值的指標:保護地產(chǎn)量當量比、保護地產(chǎn)值當量比、保護地收益當量比。
It brings about the problems of low flow - used ratio and bad harmony in flow dividing control when simultaneously operating multi - actuators with different inertia loads . this paper is aimed to solve these problems by method based on pressure decrease sensing and meter - in flow rate feedback control of actuators . in this paper , several important points including theoretical analysis , computer simulation , and experiment study will be explained 本論文主要針對因執(zhí)行器所驅(qū)動慣性負載的差異而引起流量利用率低和協(xié)調(diào)性不佳的問題,提出了一種基于壓差傳感和執(zhí)行器進油側(cè)流量反饋的分流控制方法,并進行了相應的理論分析、仿真研究和實驗研究。
Aiming at the status that the use ratio and skill of the sootblowers in plant at home are poor , the research on online monitoring of ash deposit and slag and sootblowing optimization is carried out . the research takes no . 1 boiler of the beilun power plant in ningbo as an example , which load is 600 mw electricity 針對我國電站鍋爐吹灰器利用率和利用水平低的現(xiàn)象,以電站鍋爐日常吹灰運行為研究對象,理論研究為主,研究受熱面灰污監(jiān)測模型和吹灰器優(yōu)化運行,探索電站鍋爐日常吹灰優(yōu)化運行的策略方案。
