硬件 计算机系统中所使用的电子线路和物理设备，是看得见、摸得着的实体，如中央处理器、存储器、外部设备（输入输出设备、I／O设备）及总线等。

The term "dinosaurs" was invented by Sir Richard Owen in 1842 to describe these "fearfully great rep- tiles", specifically Megalosaurus, Iguanodon and Hylaeosaurus, the only three dinosaurs known at the time.

"恐龙"这一名词是由理查得·欧文在1842年首先使用的，用来描述这种"可怕的巨型爬虫类"，特指斑龙、禽龙和热带雨林龙，这是那时仅知的三种恐龙。

However, it becomes extremely difficult to achieve it because of some negative factors, such as the imparity of language use on the internet, historical, technical, as well as market and management factors.

然而，因特网上语言使用的不平等现状，历史上形成的，技术性的以及市场和管理上的等诸多不利因素，却使因特网上语言多样性的实现变得极其困难。

The measurement is taken over a time interval and is designed to be measured on an in-service circuit.

这个比值需要在一个时间间隔内测得并且要在正在使用的线路中测量。

The Diels-Alder cycloadditions of [60] fullerene for preparation of optical limitingmaterials are discussed in chapter 3 and 6. Soluble cycloaddition derivatives of 〓aresynthesized by the reaction of 〓 with indene,1,1'-biindene andcyclopentadiene derivatives.〓Particular, the Diels-Alder cycloaddition of 〓 with1,1'-biindene under controlled conditions affords the stable monoadduct 〓〓of novel structure, which was confirmed by HPLC, FTIR, FD-MS,〓NMR,〓 NMR, HMQC and HMBC spectra, Its two bridgehead cage carbons resonate at70.91ppm, The 〓 NMR spectra showed 38 lines consistent with the 〓 symmetryassociated with [6,6] addition. The 〓 shows similar optical limitingproperties to that of 〓 in toluene for 8ns laser at wave length 532nm. Moreover, thehigh solubility of this adduct in polar solvents such as THF, acetone enables itsincorporation into sol-gel glass matrix. The thin films prepared via the sol-gel methodshow improved OL behaviour compared to those of 〓. The langmuir-Blodgett filmformation and uv-visible absorption of 〓 are also investigated. LBmonolayer of this compound is prepared on the air-water interface at 〓 mol/l. In chapter 4, three water-soluble derivatives of [60] fullerene: fullerol(1), theaddition product (2)of fullerol (1)with polyvinylpyrrolidone and fumaric acidderivative of 〓(3) are synthesized and characterized.

通过Diels-Alder环加成反应，用茚〓和1，1'-联茚〓及取代茂合成了一系列可溶性的〓环加成衍生物，发现可控制反应条件，使1，1'-联茚与〓反应，并高产率地得到具有新颖结构的单加成物，用HPLC、FTIR、FD-MS 及〓、HMQC、HMBC等多种波谱技术对其结构进行表征，测得它的两个〓杂化的桥头碳的化学位移为〓ppm，证明生成的衍生物为6∶6闭式环加成，〓NMR谱中共给出38个信号，表明〓联茚衍生物分子具有〓对称性；在波长532nm，脉冲宽度8ns的激光下，〓联茚衍生物的甲苯溶液的光限幅性能与〓的甲苯溶液相近，由于〓联茚单加成衍生物熱稳定性好，在四氢呋喃，丙酮等极性溶剂中溶解性好，能分别均匀地掺入溶胶-凝胶中，已发现它的溶胶(so1)光限幅性能优于纯〓的光限幅性能；使用Langmuir-Blodgett技术将〓联茚衍生物在空气和水的界面进行了LB单层膜和多层膜实验以及UV-Vis吸收谱研究，通过等温压缩曲线测试，证明浓度为〓〓时，〓联茚衍生物能够形成单层膜。

This single Stick, which you now behold ingloriously lying in that neglected corner, I once knew in a Flourishing State in A Forest, it was full of Sap, ful l of Leaves, and full of Boughs; but now, in vain does the busie Art of Man pret end to Vye with Nature, by tying that wither'd Bundle of Twigs to its sapless Tr unk;'tis now at best but the Reverse of what was, a Tree turn'd upside down, th e Branches on the Earth, and the Root in the Air;'tis now handled by every Dirt y Wench, condemn'd to do her Drudgery, and by a Capricious kind of Fate, destin' d to make other Things Clean, and be Nasty it self: At Length, worn to the Stumps in the Service of the Maids,'tis either thrown out of Doors, or condemn'd to its last use of kindling Fires.

请看看这根扫帚把，它现在灰溜溜地躺在偏僻的角落，而以前我曾在树林里碰见过它，那时它风华正茂，汁液充沛，枝叶繁盛。如今它完全变了样，却还有人自作聪明，想靠人类的手工同大自然竞争，拿来一束枯枝捆在它那早已干瘪的身上，结果是枉费心机，不过颠倒了它原来的位置，使它枝干朝地，根梢朝天，成为一株头朝下的树，然后落在干脏活累活的女仆们的手里使用。从此它受命运的摆布，把别人打扫干净，而自己却变得又脏又臭，在女仆们手里折腾多次之后，最后被扔出门外，或者作为引火的柴禾被投进火里。

So, the system suffers a lot from the intensive use of threading, and thus becoming very instable.

因此，该系统存在的线程大量使用了很多，因此变得非常不稳定。
