简介：平面连接的一种新、一般类型被介绍，它扩大由连接的二循环单人赛的运动学的链组成的Kempe开发的古典连接，由外卷的绞链相连。和一台锁住的设备，这些新连接有仅仅自由(DOF)的一度，它为用作使他们理想为不同目的部署有能力的结构。这里，我们为双环以分析的一个新鲜矩阵方法开始平面连接，用2D转变矩阵；一个新符号的符号。为Kempe的连接的一个盒子的另外的检查被提供。基于检查，借助于某小说代数学；几何技术，一个特别地迷人的答案被发现。物理模型被造证明在这篇论文的推导是有效的；新机制是正确的。

简介：当减肥遇见聚会．模特遭遇PARTY．美女与饕餮相逢……美丽的身材与美味之间将如何选择，心里盘算着永无止境的加减乘除．还是有第二条出路，如果丢掉肚脯上的赘肉．便意味着牺牲生命中的乐趣吗？你将永远拒绝朋友的聚会．或者在宴会上永远用眼睛享用美食？

简介：它的接触角度(CA)上的考虑固体的可湿的性质能用古典Wenzel和Cassie的方程理论上被分析。然而，对超级恐水病的表面的最近的强烈兴趣要求了二个方程的适用性的复试。我们报导热力学的分析特别地，决定普遍性二个方程的限制。用一些特殊表面，我们证明二个方程为微规模的异构的结构是有效的，然而，他们为宏规模是有病的异构的表面。而且，现在的计算建议基本热力学的分析是最强大、可靠的途径为各种各样的在结构上决定全面wettability有图案的表面。
