At the same time, the finite staff element method is used to analyze the influence of beam rigidity; and the two new methods proposed are used to analyze the influence of connect way between piles and beam; and the conclusion is obtained that the rigidity ratio between beam and piles being 0.48 is appropriate; the continuative increase of the rigidity ratio is not significant; the worst condition is that connecting way between piles and beam is hinged; the best condition is that connecting way between piles and beam is rigid. Whether is single-row pile or are double-row piles, when the front of single-row pile or the front of the front-row pile(in the double-row piles) needed excavation, it is supposed to that ought to be carefulness to excavate, because it is that the engineering cost increased greatly.
同时,用有限杆单元法,对双排桩的连梁刚度和用文中提出的方法以桩梁连接方式进行了试验和理论分析得出如下结论:在满足不相互影响排桩间距的情况下,桩顶连梁与桩的刚度比不小于0.48是合适的,此时再增加连梁刚度无意义;桩梁连接为铰结时双排桩受力变形性质最差,刚结时受力变形性质最好;不论是单排桩还是双排桩,桩前和前排桩桩前土体需要开挖时应慎重,因为这种开挖对支护结构影响很大,造价增加很多;双排桩省钱,而且抵抗变形的能力强,值得在工程中研究和广泛应用

First, it diagnoses and analyses the maglev train's suspension system and traction system by applying the FTA and fuzzy FTA method. Furthermore, it presents the new way to solute the diagnosis searching arithmetic by building the searching matrix based on the factors such as components' key weightiness, faults happen probability, searching cost. Then it can get optimal searching sequence for seeking the reason to the faults. Second, it builds the train's rank evaluation model based on multiple hiberarchy neural networks, after it takes the strategy that set the component diagnosis and whole train fault rank evaluation into two steps. Third, it deeply analyses reliability of the maglev train's power system with function-correlated feature, by the method that combining the FTA with the Markov model. Finally aiming at maintenance ahead of the fault, it proposes the blue print for the maglev train's maintenance. What's more, it introduces the design and realization to recorder for the train run data in detail.

At last, the result of real test is that the height of curl reduces averagely to 54.6% and Cpk increases from 0.94 to 1.36. The NG ppm drops off apparently before improvement from 11053.02ppm to 1267.37ppm and it doesn't'' result any other side effect of quality under relative process inspection. The benefit of improvement is estimated to save the inner failure cost of production about NT 1127.8 thousand dollars. It proves that this research case can improve effectively the curl quality of polarizer in LSG process.
最后,实际验证的结果得到翘曲改善达 54.6%,而制程能力指标Cpk由0.94提升至1.36,不良ppm已由改善前11053.02ppm大幅下降至1267.37ppm,且相关制程检验中均无产生其它品质副作用,改善效益预估分析节约台币1127.8万元生产的内部失败成本,证明此次个案研究能够有效改善偏光板连续机制程翘曲品质。

A few shareholders have questioned the wisdom of remaining in the textile business which, over the longer term, is unlikely to produce returns on capital comparable to those available in many other businesses. Our reasons are several:(1) Our mills in both New Bedford and Manchester are among the largest employers in each town, utilizing a labor force of high average age possessing relatively non-transferable skills. Our workers and unions have exhibited unusual understanding and effort in cooperating with management to achieve a cost structure and product mix which might allow us to maintain a viable operation.(2) Management also has been energetic and straightforward in its approach to our textile problems. In particular, Ken Chace's efforts after the change in corporate control took place in 1965 generated capital from the textile division needed to finance the acquisition and expansion of our profitable insurance operation.(3) With hard work and some imagination regarding manufacturing and marketing configurations, it seems reasonable that at least modest profits in the textile division can be achieved in the future.
部份股东开始质疑我们是否应该继续留在纺织产业,虽然就长期而言其投资报酬率明显低于其它的投资,但我们的理由有以下几个:(1)我们在纽贝福及 Manchester 的工厂都是当地最大的聘雇业者,员工的年龄偏高,缺乏转换工作的能力,同时我们的员工及其公会也已经尽其所能地与经营阶层配合努力改善成本结构及产品组合,以使我们的经营得以维持下去(2)管理阶层也相当努力同时坦承面对产业的问题,尤其是在1965年经营权易主后, Ken Chace 依然尽力尽力地协助我们把纺织部门产生稳定的资金流入转到获利更加的保险事业投资与购并之上(3)努力工作加上对制造与行销组合的乐观预期,我们的纺织事业在未来看起来应该可以维持一个起码的利润空间。

There is an investment postscript in our textile saga. Some investors weight book value heavily in their stock-buying decisions (as I, in my early years, did myself). And some economists and academicians believe replacement values are of considerable importance in calculating an appropriate price level for the stock market as a whole. Those of both persuasions would have received an education at the auction we held in early 1986 to dispose of our textile machinery. The equipment sold (including some disposed of in the few months prior to the auction) took up about 750,000 square feet of factory space in New Bedford and was eminently usable. It originally cost us about $13 million, including $2 million spent in 1980-84, and had a current book value of $866,000. Though no sane management would have made the investment, the equipment could have been replaced new for perhaps $30-$50 million.
有关我们在纺织业投资的&辉煌历史&还有一段后话,有些投资人在买卖股票时把帐面价值看得很重,也有些经济学者相信重置价值在计算一家公司的股价时极为重要,关于这两种说法在经过拍卖纺织机器设备后,让我好好地上了一课,卖掉的设备满满一工厂全为堪用品,原始成本为一仟三百万美金(包括近几年投入的二百万),经过加速摊提折旧后,帐面价值八十六万,虽然没有人会笨到再继续投资,但要买一套全新的设备也要花三、四千万美金。
