本研究基于BCC语料库,采用定性与定量的研究思路,借助R语言平台下的构式搭配分析法和费舍尔精确检验对“X双/对/副N”近义量词构式中N词项的搭配强度值进行测算,考察了3类量词构式中N词项的语义聚类特征、构式原型义及范畴化的认知动因和机制异同。研究发现:1)“X双/对/副N”构式在词项搭配和范畴化扩展机制上同异共存。2)构式范畴化扩展机制不仅限于Goldberg提出的隐喻、多义、例示及子类目4种承接关系,在“X双/对/副N”量词构式的扩展中还存在转喻承接关系。3)隐喻和转喻同在“X双/对/副N”量词构式的扩展中起着重要作用,但转喻机制更基础。4)汉语量词除计量功能外,分类范畴化功能也同样显著,故先前classifer、measure word及quantitative等译法都难以准确反映汉语量词的本质特征,尝试提出“classitative”的全新译法,以彰显汉语量词特色,助推后续研究。

为了有效抵御窃听者对本振光的攻击,提高连续变量量子密钥分发(continuous-variable quantum key distribution,CVQKD)系统的安全性,提出了一种基于散粒噪声方差实时监测的CVQKD系统.该系统采用散粒噪声方差标定技术,在原有的CVQKD系统中加入散粒噪声方差实时监测模块,通过本振光强和散粒噪声方差的线性关系评估出实时的散粒噪声方差,再计算系统准确实时的密钥率来判断当前系统是否处于安全状态.实验上也表明了该系统能够有效抵御Eve对本振光的攻击,提高CVQKD系统的安全性.

目的探讨肺最大通气量(MVV)实测值占预计值百分比(MVV%pred)在围术期的评估价值。方法选取61例行胸与上腹部手术后肺功能异常的患者,将50%≤MVV%pred0.05)。3种方法获得的MVV值中,实测值与方法一公式计算获得的估算值差异无统计学意义(P>0.05),而与方法二公式计算获得的估算值差异有统计学意义(P<0.05);方法一与方法二公式计算获得的预测值差异也有统计学意义(P<0.05)。A组患者术后并发症发生率为6.1%(2/33),明显低于B组的39.3%(11/28),差异有统计学意义(P<0.05)。结论 MVV%pred<50%的患者的肺通气功能减退与RV、TLC、气道阻力增高的程度明显高于50%≤MVV%pred<80%的患者,但两者弥散功能损害差异不明显。对不能配合完成MVV测试获得MVV%pred实测值的患者,可用公式MVV=FEV_1×35/MVV预计值计算获得的估算值对手术适应证进行评估。
