查询词典 in recent years

Dust the baseboards? Are you kidding? Ironically, though, American women seem quite satisfied with their housekeeping, according to a national survey conducted in 1995-96. Besides that, people are designing their homes with low-maintenance features--tile in bathrooms and kitchens as well as marble on countertops--to cut down on the need for frequent cleaning. Even so, more and more people are hiring outside help to clean their houses. A Roper poll found that one in six Americans hired cleaning help last year, up from one in 10 in 1986. One professional housecleaning service, Merry Maids, has grown to over 800 franchises in recent years.

但可笑的根据一九九五／六年做的一项全国性调查美国妇女似乎对他们的家务整理挺满意除此之外人们以较不需要时时清洁的材料来设计他们的家--在浴室及厨房贴磁砖以及做大理石的台面--减少打扫的次数即使如此越来越多的人雇用外人协助清理屋子一项洛普民意调查发现去年有六分之一的美国雇用清洁服务较一九八六年的十分之一比率上升许多一个专业性的家务清理服务「快乐女佣公司」在最近几年已成长到有八百多家的连锁店

Because the techniques of the biochemical waste treatment are very important, the techniques of the cultivation of the microorganism have received more attention in recent years. A study is conducted to analyze the steady states and dynamic bechavior of the reactions of the cell-substrate and the prey-predator interaction in two chemostats in series. For the reaction of cell-substrate in two chemostats in series, if the specific growth rate of the Monod model is used for the cell , there are three types of steady states for this reaction system. These three types of steady states and stability are analyzed in detail. The dynamic behavior of this reaction system is analyzed by the numerical method and computer graphs. The results show that the dynamic behavior of this system consists of stable steady states.

由於生物废弃物的处理技术相当重要，故最近几年来微生物的混合培养技术深受大家的重视，本研究实施菌类－基质(Cell-Substrate)和被捕食者－捕食者(Prey-Predator)相互作用之生化反应在两个生化反应槽串联之稳定状态和动态分析，对於菌类－基质之生化反应，若以Monod模式来表示菌类之比生长速率，则此两个生化反应槽串联之反应系统共有三种型态之稳定状态，本研究对此三种型态之稳定状态和稳定度作深入的分析，对於此反应系统之动态行为，则由电脑运用数值分析的方法及电脑绘图进行分析工作，动态分析的结果显示此生化反应系统之动态行为，以稳定之稳态为主。

The average level of the soil available potassium was 119.96 mg/kg, which decreased 18.94 mg/kg and 1.05 mg/kg one year averagely. But the decreasing trend alleviated in recent years. There were 39.5 kg/hm^2 nitrogen and 30.9 kg/hm^2 phosphorus (P2O5) more than needed averagely, and 150.0 kg/hm^2 potassium (K2O) in deficiency. Though the fertilizer application was high and the rate of fertilizer was 647.96 kg/hm^2 in nutrient, the ratio of organic to inorganic was still unreasonable. The ratio of the chemical fertilizer nitrogen phosphorus (P2O5) and potassium (K2O) was 1:0.42:0.14. The nitrogen application was enough and even higher than that was needed. The phosphorus was proper elementarily and potassium was in deficiency. The yield of wheat which was the main crop increased slightly and that of other autumn harvest crops was stable.
