Instantaneous motions of the end effector of the typical industrial serial 6-DOF and 5DOF robots are also studied using reciprocal screw theory, The constrained and permitted motions at special configurations are given. Furthermore, the satisfied conditions for the special configurations are discussed, and in the reference coordinate system general expressions of the reciprocal screw and existed motion screw and the subspaces of the permitted rotational axes are obtained under all circumstances at special configurations.

The results are the following: When calculating the motion mass, it is better to use idler's equivalent mass instead of the rotating part mass and serial idler's rotating inertias and equivalent mass are calculated. The accurate analysis result for the deflection curve length of the belt shows: The error calculated by the approximate parabola length is lower than 10〓. Thus the approximate method is accurate enough for calculation. The relations between the running resistances coefficient and the belt velocity are studied by experiment, which are the bases for calculating the linear coefficient values between them.

Base on above studies, some conclusions were obtained as follows:(1) ore-forming background of the studied ferromanganese crusts are mainly controlled by intensity of Antarctic Bottom Waters and variations of material source;(2) it is confirmed that the ferromanganese crusts are mainly hydrogenetic and their composition are affected by volcanic and continental material simultaneously; there are no obvious phosphatization reconstruction and element reaction occurred in them, so they have important paleoceanological significance;(3) from researches on element occurrence modes in the new-type ferromanganese crusts and the lying sediments, it is proposed that there is no great biological affection on the crusts formation and their composition mainly came from the adsorptive action of the ferromanganese oxides in them;(4) two major types of ore-controlling factors are identified through compilation of ore-controlling factors, which are geological and oceanic factors;(5) considering the long-term variation trends of the crusts composition, combing the U-series and 10Be isotope dating results, it is proposed that the ore-forming processes of ferromanganese crusts in the studied areas can be divided into three major stages (5.6~2.8 Ma, 2.8~2.7 Ma and since 2.7 Ma), and then the activities of AABW since the Late Miocene, changes of input flux coming from volcanic and continental material are confirmed.

通过研究，得出如下结论：(1)研究区铁锰结壳的成矿背景主要受控于南极底流强弱及物源供给的变化；(2)证实铁锰结壳主要为水成成因，同时其物质组成也受一定程度的火山和陆源物质的影响；结壳自形成以来没有遭受到明显的磷酸盐化等成岩后期改造和元素再迁移，具有重要的古海洋学意义；(3)通过新型铁锰结壳及下伏沉积物元素赋存状态的研究，认为生物作用对研究区结壳的形成并没有很大的直接影响，其物质成分主要来自于结壳中铁锰氧化物的吸附作用；(4)在控矿要素的研究中，归纳出了地质与海洋两大类结壳控矿要素；(5)根据结壳成分长周期变化趋势，结合铀系和10Be测年结果，将研究区结壳的形成过程划分为三个主要阶段(5.6~2.8 Ma，2.8~2.7 Ma和2.7 Ma以来)，并确定了晚中新世以来研究区南极底流的活动情况、火山和大陆来源物质输入量的变化。

We first introduced a new concept called transitive resolvable idempotent symmetric quasigroup, proved that the necessary condition for the existence of TRISQ is also sufficient, then presented a tripling construction for LKTS by using TRISQ instead of TKTS, thus removed the condition "there exists a TKTS" in Denniston''s tripling construction for LKTS; We also improved J. Lei''s product construction for LKTS by removing the condition "there exists a TKTS".

我们首先引入了可迁可分解幂等对称拟群的新概念，证明了TRISQ存在的必要条件也是充分的，然后给出了用TRISQ取代可迁Kirkamns三元系的LKTS的三倍构造法，这样就去掉了在Denniston的关于LKTS的3倍构造中的条件"存在一个TKTS"；我们用TRISQ取代TKTS改进了雷建国的关于LKTS的一个积构造方法，从而去掉了该构造方法中的条件"存在一个TKTS"。

Seems as though Terry purchased what he thought was a Canon A630 from one of the stores CompUSA was closing back in March, but when his step-daughter opened the box a few weeks ago, it was empty. Assuming he'd get a refund, Terry drove to the nearest CompUSA, where he was told that all liquidation sales were handled by a third party and not CompUSA, and that he would have to contact CompUSA's attorneys to secure a refund. Undaunted, Terry then wrote a letter to CompUSA's CEO, whose "Executive Care" assistant replied and said that Terry should have been more careful to inspect the box when he purchased the camera, and that the prominent ALL SALES ARE FINAL signs around the store and on the receipt weren't just for show.

一名德州男子 Terry Heaton 于三月份时，趁着 CompUSA 清仓大甩卖，花了269美金买了一台 Canon A630 数码相机给他的女儿，没想到几周后，他的女儿打开盒子时，才发现原本应该装着相机的盒子却是空的，事后当 Terry 拿着盒子回到店里要求退钱时，却得到「此次清仓拍卖系由接手商品的批发商所负责，而非 CompUSA」的响应，于是不屈不挠的Terry便写了一封信给CompUSA的总裁Roman Ross，没想到却也只是收到「购物时需小心检查商品」及印在收据上的「货物既出，盖不退换」的善意提醒。

In the second chapter several new concepts of elasto-plastic fuzzy stiffness and element are proposed. The fuzzy element matrixes corresponding to the elasto-plastic fuzzy element are also established. In order to use the bilinear and trilinear restoring force modles on analysis seismic responses of structures. A fuzzy mathematical method for dealing with the critical points of the restoring force curve is proposed too.
