The chemical-petrographic types of these meteorites are presented below.Six are unequilibrated ordinary chondrites,including three H3 and three L3;92 meteorites are equilibrated ordinary chondrites,including 24 H-group(13 H4,10 H5,1 H6),64 L-group(2 L4,44 L5,18 L6) and 4 LL-group(3 LL4,1 LL5);the other two belong to stone-iron meteorites.In 6 unequilibrated ordinary chondrites,chondrules are well-shaped,and olivine and low-Ca pyroxene are commonly zoned and have wide ranges of composition.The olivine and low-Ca pyroxene in the other 92 equilibrated ordinary chondrites have similar composition,respectively,and to some degree it reflected thermodynamics equilibration in olivine and lowCa pyroxene.

并根据矿物-岩石学特征，划分了它们的化学-岩石类型：6块属于非平衡型普通球粒陨石(H3和L3群各3块)；92块属于平衡型普通球粒陨石，包括：H群24块(13块H4，10块H5，1块H6)，L群64块(2块L4，44块L5，18块L6)，LL群4块(3块LL4，1块LL5)；另外两块属于石-铁陨石。6块非平衡型普通球粒陨石保存了原始的岩石学和矿物化学特征，包括：清晰的球粒结构、橄榄石和低钙辉石具有明显的成分环带以及极不均一的化学组成等。92块平衡型普通球粒陨石中的橄榄石和低钙辉石显示出均一的化学组成，表明它们达到了一定的热力学平衡。

The scientists found that the ship's builder, Harland and Wolff, in Belfast, struggled for years to obtain adequate supplies of rivets and riveters to build the world's three biggest ships at once: the Titanic and two sisters, Olympic and Britannic.Each required three million rivets, and shortages peaked during Titanic's construction.

科学家证实，贝尔法斯特市的造船厂同时承造了三艘当时世界上最大的巨轮，即泰坦尼克号和她的两搜姊妹船：奥林匹克和大不列颠号，而每艘大船需要300万枚铆钉--铆钉缺口在造泰坦尼克号时达到最大，船厂负责人哈蓝德和沃尔弗耗了数年时间来解决铆钉和铆钉工人不足的棘手问题。

Sometimes I thought if digging a hole under the place where theymade their fire, and putting in five or six pounds of gunpowder,which, when they kindled their fire, would consequently take fire,and blow up all that was near it: but as, in the first place, Ishould be unwilling to waste so much powder upon them, my storebeing now within the quantity of one barrel, so neither could I besure of its going off at any certain time, when it might surprisethem; and, at best, that it would do little more than just blow thefire about their ears and fright them, but not sufficient to makethem forsake the place: so I laid it aside; and then proposed thatI would place myself in ambush in some convenient place, with mythree guns all double-loaded, and in the middle of their bloodyceremony let fly at them, when I should be sure to kill or woundperhaps two or three at every shot; and then falling in upon themwith my three pistols and my sword, I made no doubt but that, ifthere were twenty, I should kill them all.

这时，我已怒不可遏了，但还是强压心头的怒火，往回走了二十多步，来到一片矮树丛后面。靠着这片矮树丛的掩护，我一直走到那棵大树背后。那里有一片小小的高地，离那些野人大约有八十码远。我走上高地，把他们的一举一动看得清清楚楚。事情已发展到万分紧急的关头了，因为我看到有十九个野人挤在一起坐在地上，他们派出另外两个野人去宰杀那可怜的基督徒。看来，他们是要肢解他，一条胳膊一条腿地拿到火上去烤。我看到那两个野人这时已弯下腰，解着那白人脚上绑的东西。我转头对星期五说：&听我的命令行动。&星期五说他一定照办。我就说：&好吧，星期五，你看我怎么办就怎么办，不要误事。&于是，我把一支短枪和一支乌枪放在地下，星期五也跟着把他的一支鸟枪和一支短枪放在地下。我用剩下的一支短枪向那些野人瞄准，并叫星期五也用枪向他们瞄准。然后，我问星期五是否准备好了，他说：&好了。&

Results: Twenty-three cases and 17 cases had one Specie Bacteria,21 and 23 cases had two species bacteria,2 and 6 cases had three Species bacteria in airway aspirates groups and BALF groups respectively.

In order to meet the need of economic development for large-specification roll of steel plates, technical improvements have been carried out in the hot-rolling mill. The six sets of high pressure water pump, which cannot provide high enough speed of water supply for rolling, is replaced using three sets of high pressure centrifugal pump. The working mode of three sets of high pressure centrifugal pumps is that two pumps work and another one is spare. After the project has been carried out other problems emerge, for example, the electromotor becoming very heat and the pump being frequently attainted.

为了适应经济发展对轧制大规格的热轧板卷的需要，热轧板厂对轧线进行了技改，将6台不能满足快节奏高速轧制供水的高压柱塞泵更换为3台高压离心泵，三台高压水泵采取两用一备工作状态，投运以来，又出现电机严重发热，泵频繁损坏的问题。

This article has selected three methods of weight calculation: single item index method of weight; synthesis index method of weight; entropy method of weight After the expatiation of theories and means, we analyzed example by using the fuzzy comprehensive evaluation method baaed on these three kinds of methods of weight calculation, and then came to the conclusion through contrast: the first method is very sensitive to superscale; the other two methods, which consider more factors' influence, can generally reflect the real status of water quality, and the results are consistent and relatively better.

现选取了单项评价指标权重法、综合权重法以及熵权法三种不同的权重计算法，分别详述了其计算原理和方法，并在基于这三种权重计算法的基础上采用模糊综合评判法对实例进行分析，最终通过对比得出结论：基于单项评价指标权重法的模糊综合评判法对单个超标因子比较敏感；基于综合权重法和熵权法的模糊综合评判法则综合考虑了各个指标因子对评价结果的影响，能够较全面的反映水质的实际情况，评价结果几乎一致，且相对较好。
