The final refinement converged to R=0.0686 and 0.0688. In the two complexes, the metal atom is coordinated with one nitrogen atom of alkylamine and three sp^2 nitrogen atoms from NTB and one oxygen atom from H~2O to form a distorted trigonal-bipyramid configuration.

配合物中的金属原子与配体NTB分子中的一个烷胺氮原子、三个sp^2氮原子和一个水分子中的氧形成五配位的扭曲三角双锥构型。

Dr Gregg Fonarow, Eliot Corday Professor of Cardiovascular Medicine at UCLA and coauthor of this study, noted, Experimental studies suggest that metformin improves myocardial function via activation of a signaling mechanism (AMP-activated protein kinase) independent of antihyperglycemic effects.

另两位合作研究者，加州大学洛杉矶分校心血管内科教授Gregg Fonarow博士和Eliot Corday博士还提到："实验室研究提示，二甲双胍改善心肌功能是通过激活了一种不同于降糖作用的信号机制（AMP-活化的蛋白激酶）"这些研究结果共同提示，二甲双胍可能具有心脏保护作用，这一作用是通过在分子水平增强心脏功能来实现的。

The self-centering mechanism design of bipolar endoprosthesis has advocated the use of offset centers of rotation between the inner and outer joint bearing surfaces to generate a self-centering moment on loading to prevent impingement of polyethylene rim and stem neck or cup fixed at wrong place. The design was used popularly, but the function of self-centering mechanism was discussed in very few papers. Three bipolar endoprosthesis were evaluated: UNIQHIP system, UHR system, and AML system.

双极式半人工髋关节的离心复位机构，是利用髋臼外帽的球心与股小球的球心两者在不同点，来防止发生髋臼外帽固定於髋臼中某角度卡住不动，而使股骨柄颈部固定磨损超高分子聚乙烯内衬之一边缘，进而加速超高分子聚乙烯内衬之磨耗，造成骨溶蚀与人工髋关节的松脱。

The result is that both tin atoms are five-coordination, have a distorted trigonal bipyramidal geometry with an additional week interaction between another oxygen atom and tin atom.

分子中四个羧酸酯基有桥联双齿和单齿两种不同的配位模式；在内环锡和外环锡的配位单元中，锡均形成具有五配位的畸变三角双锥配位构型，同时另有一氧原子与中心锡原子之间有弱相互作用。

On the other hand, reaction of lactol derived from D-mannose and D-glucose with Grinard reagent of propargyl bromide also proceed both withanti stereoselectivity and with high anti-specificity.

链增长及目标分子中的碳碳双键是由一步Wittig反应和一步末端炔的烷基化再部分氢化而获得，双键构型-选择性可达到95％以上。

This work is mainly concerned with molecular magnetism of polynuclear complexes and supramolecular crystal engineering.

本论文围绕多核配合物的分子磁学和超分子晶体工程这两个最为活跃的前沿研究领域，选用大环配体tacn（1，4，7-三氮杂环壬烷）和含有外延桥的双草胺。。。
