(提示患儿经胸骨正中切口,在体外循环辅助下行ASD直视修补术,采用自体心包补片,双头针聚丙烯线连续缝合法。术后恢复良好,顺利出院。出院后一般情况,各项检查无异常,随访1年后失访。患儿从4岁时开始,受凉感冒或活动后出现口唇、指趾端紫绀,且症状逐渐加重,5岁时来院就诊,体查:体重14kg,经皮氧饱和度86%。心前区隆起,心脏搏动增强。叩诊心界向两侧扩大。心率122次/分,心律整齐。心音清晰有力,未闻及杂音。双肺呼吸音清,未闻及干、湿啰音。唇甲轻度紫绀,双下肢无水肿。)根据患儿病史,你认为最可能的诊断是()

Across a wide variety of fields, data are being collected and accumulated at a dramatic pace. There is an urgent need for a new generation of computational theories and tools to assist humans in (96) useful information (knowledge) from the rapidly growing (97) of digital data. These theories and tools are the subject of the emerging field of knowledge discovery in database (KDD). At an abstract level, the KDD field is concerned with the development of methods and techniques for making (98) of data. The basic problem addressed by the KDD process is one of mapping low-level data(which are typically too voluminous to understand and digest easily) into other forms that might be more (99) (for example, a short report), more (100) (for example, a descriptive approximation or model of the process that generated the data), or more useful (for example, a predictive model for estimating the value of future cases). At the core of the process is the application of specific data-mining methods for pattern discovery and extraction.

(99)是()

A.dense

B.compact

C.extensile

D.short
