possession of it, with the reflection that Mr. Micawber’s troubles
had come to a crisis at last, I thought it quite a paradise.

All this time I was working at Murdstone and Grinby’s in the
same common way, and with the same common companions, and
with the same sense of unmerited degradation as at first. But I
never, happily for me no doubt, made a single acquaintance, or
spoke to any of the many boys whom I saw daily in going to the
warehouse, in coming from it, and in prowling about the streets at
meal-times. I led the same secretly unhappy life; but I led it in the
same lonely, self-reliant manner. The only changes I am conscious
of are, firstly, that I had grown more shabby, and secondly, that I

was now relieved of much of the weight of Mr. and Mrs.
Micawber’s cares; for some relatives or friends had engaged to
help them at their present pass, and they lived more comfortably
in the prison than they had lived for a long while out of it. I used to
breakfast with them now, in virtue of some arrangement, of which
I have forgotten the details. I forget, too, at what hour the gates
were opened in the morning, admitting of my going in; but I know
that I was often up at six o’clock, and that my favourite lounging-
place in the interval was old London Bridge, where I was wont to
sit in one of the stone recesses, watching the people going by, or to
look over the balustrades at the sun shining in the water, and
lighting up the golden flame on the top of the Monument. The
Orfling met me here sometimes, to be told some astonishing
fictions respecting the wharves and the Tower; of which I can say
no more than that I hope I believed them myself. In the evening I
used to go back to the prison, and walk up and down the parade
with Mr. Micawber; or play casino with Mrs. Micawber, and hear
reminiscences of her papa and mama. Whether Mr. Murdstone
knew where I was, I am unable to say. I never told them at
Murdstone and Grinby’s.

Mr. Micawber’s affairs, although past their crisis, were very
much involved by reason of a certain ‘Deed’, of which I used to
hear a great deal, and which I suppose, now, to have been some
former composition with his creditors, though I was so far from
being clear about it then, that I am conscious of having
confounded it with those demoniacal parchments which are held
to have, once upon a time, obtained to a great extent in Germany.
At last this document appeared to be got out of the way, somehow;
at all events it ceased to be the rock-ahead it had been; and Mrs.

Micawber informed me that ‘her family’ had decided that Mr.
Micawber should apply for his release under the Insolvent Debtors
Act, which would set him free, she expected, in about six weeks.

‘And then,’ said Mr. Micawber, who was present, ‘I have no
doubt I shall, please Heaven, begin to be beforehand with the
world, and to live in a perfectly new manner, if―in short, if
anything turns up.’

By way of going in for anything that might be on the cards, I
call to mind that Mr. Micawber, about this time, composed a
petition to the House of Commons, praying for an alteration in the
law of imprisonment for debt. I set down this remembrance here,
because it is an instance to myself of the manner in which I fitted
my old books to my altered life, and made stories for myself, out of
the streets, and out of men and women; and how some main points
in the character I shall unconsciously develop, I suppose, in
writing my life, were gradually forming all this while.

There was a club in the prison, in which Mr. Micawber, as a
gentleman, was a great authority. Mr. Micawber had stated...以确保缩短产品的生产周期。 与此同时，除利用计算机制图外还将在计算机这个载体上实现产品的强度分析、可靠性预估和三维立体设计，将原来需要在生产中发现和解决的工艺问题、局部结构问题及装配性问题等方面提至生产前进行防范，缩短产品的试制期。 产品的标准化与模块化 在产品出现多元化的同时，泵作为通用产品，总体总量依旧巨大。在市场中，除出现技术性竞争外，产品的价格竞争尤其是通用化产品的价格竞争是必然趋势。在产品出现多元化的趋势下，要实现产品价格的竞争优势，提高产品零部件的标准化程度，实现产品零部件的模块化是必须的。在众多零部件实现模块化后，通过不同模块的组合或改变个别零件的特性，以实现产品的多元化。同时，只有当零部件标准化程度提高后才有可能基于产品的多元化基础上实际规模化的零部件生产，用以降低产品的生产成本和形成产品的价格竞争优势，也可以在产品多元化的基础上进一步地缩短产品的交货周期。


国内泵技术新趋势(2 )
泵内在特性的提升与追求外在特性
所谓泵的内在特性是指包括产品性能、零部件质量、整机装配质量、外观质量等在内的产品固有特性，或者简称之为品质。在这一点上，是目前许多泵生产厂商所关注的也是努力再提高、改进的方面。而实际上，我们可以发现，有许多的产品在工厂检测符合发至使用单位运行后，往往达不到工厂出厂检测的效果，发生诸如过载、噪声增大，使用达不到要求或寿命降低等等方面的问题；而泵在实际当中所处的运行点或运行特征，我们称之为泵的外在特性或系统特性。
技术人员在进行产品设计时，为提高某一产品的百分之一效率常常花费不少心思；而泵运行如果偏离设计的高效点，实际运行的效率远不止降低百分之一。现在，泵生产厂家同时为用户配套包括变频在内的控制设备及成套设备，实际上已介入到泵的外在特性的追求上了。在此基础上，再关注泵的集中控制系统，提高整个泵及泵站运行效率，则是在泵的外在特性的追求上更上一层楼。
从销售角度看，推销产品即是在推销泵的内在特性；而关注泵的外在特性则是生产厂商不仅是推销产品，更是在推销泵站（成套项目）。从使用角度看，好的产品必定是适合运行环境的产品而非出厂检测判别的产品。 机电一体化的进一步发展
正如科技术的发展一样．现阶段科技领域中交叉科、边缘科越来越丰富，跨科的共同研究是十分普遍的事情，作为泵产品的技术发展亦是如此。以屏蔽式泵为例，取消泵的轴封问题，必须从电机结构开始，仅局限于泵本身是办法实现的，解决泵的噪声问题，除解决泵的流态和振动外，同时需要解决电机风叶的噪声和电磁场的噪声；提高潜水泵的可靠性，必须在潜水电机内加设诸如泄漏保护、过载保护等措施；提高泵的运行效率，须借助于控制技术的运用等等。这些无一明要发展泵技术水平，必须从配套的电机、控制技术等方面同时着手，综合考虑，大限度地提升机电一体化综合水平。 新材料新工艺的加速利用
过去的十多年来，新材料和新工艺的运用是推动泵技术发展的一个主要的因素。泵用材料从铸铁到特种金属合金，从橡胶制品、陶瓷等典型非金属材料到工程塑料，在解决泵的耐腐蚀、耐磨损、耐高温等环境上都发挥了突出的作用。同时新工艺的运用，又更好地使新材料运用到泵的零部件乃至整个泵当中。如国外有些厂商已设计并推出了全部采用工程塑料制成的泵。比用一般金属材料生产的泵在强度上毫不逊色，在耐蚀耐磨上更胜一筹。又比如利用新的表面涂覆技术和表面处理技术，同样可解决泵的抗蚀和抗磨问题。新材料的进一步发展和新工艺的运用深入，在泵领域内的应用将更加广泛。
