模糊数学在房地产市场估价法中的应用研究

如何解决市场估价法实际应用中普遍存在的可比实例选择的随意性,因素修正的主观性、不完备性,交易案例不易得到等难题,是房地产估值迫切需要解决的问题。为了解决传统估价方法存在的问题,本文把模糊数学方法引入房地产市场估价法中,利用模糊数学的隶属原则,用特征因素函数值所组成的数组表示房地产的属性,通过计算待估商品房和案例商品房之间的贴近度,找出最相似的案例,再通过贴近度进行指数平滑,求出待估商品房的价格。福建省自然科学基金资助项目:模糊数学在房地产市场估价法的应用研究;项目编号:2009J0131

乳腺癌前哨淋巴结活检及其微转移检测的临床意义

【目的】探讨美蓝法示踪和定位行乳腺癌前哨淋巴结活检（SLNB）的可行性及其临床意义,并探索常规病理检查（HE染色）、免疫组化染色（IHC染色）及逆转录聚合酶链反应（RT-PCR）技术对判断前哨淋巴结（SLN）微转移灶的价值。【方法】66例乳腺癌患者,用美蓝示踪行SLNB,对SLN及腋窝淋巴结（ALN）进行HE染色;随机选取40例SLN进一步行细胞角蛋白19（CK19）的IHC染色及RT-PCR检测;比较3种方法对SLN微转移灶检出的敏感性、准确率及假阴性率的差异。【结果】66例中,美蓝示踪成功检出63例,检出率达95.5%。IHC与RT-PCR比较无差异,而与HE比较差异有显著性。【结论】美蓝法SLNB也有很高的检出率,由于常规病理检查对微转移的诊断率低,结合IHC及RT-PCR检测能则有效判断乳腺癌腋淋巴结转移状态,提高SLN中微转移的检出率,降低假阴性率

Mechanism of Surface Formation for Two-dimensional Ultrasonic Vibration Assisted Grinding of Monocrystal Silicon with Vertical Workpiece Vibration

通过单晶硅磨削试验以及单颗金刚石磨粒划擦试验,分析垂直于工件平面的二维椭圆超声振动磨削单晶硅的表面形成机制。椭圆超声振子由压电陶瓷晶体与金属弹性体粘接制成,其伸缩模态和弯曲模态频率相同,当输入具有一定相位差的两个交流电压信号时产生二维椭圆振动。试验结果表明,由于二维椭圆振动的施加改变了单晶硅的材料去除机制,加工表面质量明显提高,表面粗糙度显著降低,磨削沟槽变浅而宽,切屑变厚而短,单晶硅材料延性域去除比例增加;通过改变超声振动振幅与磨削深度之间大小关系,可实现磨削刃对工件的连续性接触去除和断续性接触去除两种模式的转变。The mechanism of surface formation for two-dimensional elliptic ultrasonic vibration assisted grinding with the vertical direction to workpiece is investigated by grinding experiments and single point diamond abrasive scratching experiments on monocrystal silicon.The vibrator is produced by bonding a PZT on a metal elastic body,frequencies of both longitudinal mode and bending mode are nearly the same,and an elliptic motion occurs when two alternating current signals with phase difference are applied to the PZT.The experimental results show that the workpiece surface quality is improved obviously,and the surface roughness is decreased significantly.And moreover,the grinding grooves become much shallower and wider,and the chip is also much thicker and shorter.It is known that the percent of ductile mode removal material increases.In addition,as the relation between vibration amplitude and grinding depth of cut is changed,two kinds of material removal mechanism,continuous contact and interrupting cutting,can be realized.国防科研资助项目(62301090103
