篇1：capacity 可数吗

近义词：ability

一、意思：n. 能力；才能

二、读音：英 ['blti]，美 ['blti]

三、例句：

She has the ability to keep calm in an emergency

她有处变不惊的本事。

四、词汇用法：

ability的基本意思是泛指做各种事情的“能力”。可以指体力方面的，也可以指智力方面的`，有时还指法律上的能力；可以是生来就有的生理功能，也可以是后天通过实践学得的。作此解时仅指能力而不涉及能力的高低，只用单数形式。

ability指“智力，技能”时用作可数名词，且常用于复数形式。

ability也可指“聪明，智慧”，这时用作不可数名词。单独用ability或abilities时除带后置修饰语或有上下文提示者外，一般都指智力。

篇2：Acid and Alkali Buffer Capacity of T

Acid and Alkali Buffer Capacity of Typical Fluvor-Aquic Soil in Huang-HuaiHai Plain

Soil acid and alkali buffer capacity, as a major indicator for evaluating its vulnerability and resistibility to acidification and alkalization, is an important factor affecting the sustainable agriculture, through knowledge on which soil acidification process can be predicted and modified. In this study, titration curve method was adopted to investigate the pH buffer capacity (pHBC) of fluvor-aquic soil, and separate titration curves were established by adding incremental amounts of either standardized hydrochloric acid (HCl) (0.12 mol L-1) or sodium hydroxide (NaOH) (0.10 mol L-1) to soil suspended in deionized water (soil:solution=1:5). Soil pH was measured after 7 d resuspension and isothermal equilibrium (T= 25℃). Linear regressions were fitted to the linear portion of each titration curve and the slopes of these lines were derived as the soil pHBC. The results showed that significant correlations between the amounts of adding acid or alkali and each pH change were presented, and titration curve method was feasible for measurement of pHBC on typical fluvor-aquic soil in Huang-Huai-Hai Plain, and the coefficients of determination were higher than the similar researches on acid soil (R2= 0.96). The slope-derived pHBC of acid and alkali were 158.71 and 25.02 mmol kg-1, respectively. According to the classification of soil buffer systems, the soil tested belongs to the calcium carbonate buffer system, carbonates contribute the most to pHBC, and the contribution of soil organic matter relatively less than it.

篇3：Pit Bearing Capacity Effect on Statu

Pit Bearing Capacity Effect on Status of Soil Plug During Pile Driving in Ocean Engineering

Abstract：Foundation piles of the offshore oil platforms in the Bohai Bay are usually longer than 100 m with a diameter larger than 2 m. Driving such long and large-sized piles into the ground is a difficult task. It needs a comprehensive consider ation of the pile dimensions, soil properties and the hammer energy. Thoughtful drivability analysis has to be performed in the design stage. It has been shown that judging whether the soil column inside the pile is fully plugged, which makes the pile behave as close-ended, strongly influences the accuracy of drivability analysis. Engineering practice repeatedly indicates that the current methods widely used for soil plug judgment often give incorrect results, leading the designers to make a wrong decision. It has been found that this problem is caused by the ignorance of the bearing capacity provided by the soil surrounding the pile. Based on the Terzaghis bearing capacity calculation method for deep foundation, a new approach for judging soil plug status is put forward, in which the surcharge effect has been considered and the dynamic effect coefficient is included. This approach has been applied to some practical engineering projects successfully, which may give more reasonable results than the currently used method does. 作者： Author： YAN Shu-wang  ZHOU Qun-hua  LIU Run  DONG Wei 作者单位： School of Civil Engineering, Tianjin University, Tianjin 300072, China 期 刊： 中国海洋工程(英文版)   ISTICEISCI Journal： CHINA OCEAN ENGINEERING 年，卷(期)： , 25(2) 分类号： P752 Keywords： ocean platform pile    pit bearing capacity    plug status    static equilibrium    driveability    机标分类号： P7 TP3 机标关键词： Ocean Engineering    Pile Driving    During    Soil Plug    Bearing Capacity    bearing capacity    soil plug    effect coefficient    calculation method    approach    analysis    deep foundation    current methods    results    influences    practical    Bohai Bay    provided    practice    diameter 基金项目： This research was financially supported by the National Natural Science Foundation of China
