The main factors that can affect the strength of base PAN fiber and how its hydrolysis reaction happened in alkaline conditions were discussed.

应用红外光谱仪、元素分析仪、比表面分析仪等对基体聚丙烯腈纤维及其部分水解PAN-COOH型离子交换纤维进行了表征，讨论了影响基体PAN纤维强度的主要因素和碱性条件下的水解反应获得了干态水解PAN纤维的性能指标：强度8.3 cN/dtex，交换容量0.26 mmol/g ， BET比表面积为0.58平方公尺/g的PAN-COOH型离子交换纤维，并较为详细地讨论了该纤维氰基转化成羧基的比率，羧基在纤维表面的排列及最大水解量。

The area of the cone to radius from center hub is expressed as a ratio (AR, A/R, or A:R).

锥体的区域对半径从中心插孔被表达作为比率(AR， A/R，或A ：R)。

The deep cultivation-root cutting in before winter stage would increasethe weight and ratio of root system in middle and lower layer,the resultswould decrease the root redundancy.

冬前深耘断根可增加中、下层根系的重量和比率，降低根系生长冗余性，控制最高总茎数，提高成穗数及成穗率，使籽粒产量中来自花后光合器官输送的比例增加，从而使产量提高，因而在旱地高产麦田应推广冬前深耘断根。6研究了降水量对旱地高产小麦耗水规律及产量的影响，拔节前降水多且占比重高，土壤供水量及占比重少，拔节后降水量减少且占比重低，土壤供水量及占比重高，利于在旱地高产麦田形成高产。

Declining balance method; reducing charge method: In depreciation where the annual charge for depreciation is the amount obtained by applying a diminish ing rate to the original cost of the asset.

余额递减法；递减计提法：即在折旧时采取对资产的原始成本使用一个递减比率的方法计算年折旧额

Methods Among60cases of patients suffering chronic renal exhaustion and being kept with hemodialyˉsis,hematocrits of the blood from the artery end of dialytic pipeline were analysed5times in the procession of hemodialysis,and the descendant ratios of blood capacitywere calculated according to the varieties of hematˉocrits.Simultaneously,the varieties of blood pressure were monitored,in order that the appropriate dry body weight and dialytic velocities would be determined.

对60例慢性肾衰维持性血液透析的患者，在透析过程中分5次检测透析管路动脉端血液红细胞压积，并根据红细胞压积变化血容量下降比率，同时监测血压变化，以此确定合适的干体重和透析速度。

From this it becomes clear that apertures must be designed with an area ratio in excess of 0.6 for a repeatable process.

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

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
