The compressibility properties of systems consisting of generic rotating rigid triangles are analyzed and discussed.It is shown that these systems which are usually associated with auxeticity can exhibit strongly anisotropic properties for certain conformations, which may give rise to the anomalous property of negative linear compressibility(NLC), that is, the system with particular geometry will expand along one direction when loaded hydrostatically. It is also shown that through carefully choosing the geometric features(i.e. the dimensions and the alignment of the rotating triangles as well as the angles between them) and the direction along which the linear compressibility is measured, one may control the magnitude and range of the NLC. All this provides a novel but effective method of manufacturing the systems which can be tailored to achieve particular values of NLC to fit particular practical applications.

问:  我和丈夫张某是再婚,我们双方婚前各自都有子女需要抚养,各自都有老人需要赡养。他每月工资五千元,我每月工资四千元。婚后我们实行了AA制,约定各自的孩子各自抚养、各自的父母各自赡养。家庭开支等各项费用,月初记账,月底结算平摊。婚后我们一直租房住,眼下房租上涨,且租房也不方便,最近我们合资买了房,他出资30%,我出资70%,我们花了80万元合买了一套楼房。请问:在进行房屋产权登记时,我们可否要求
