Then the son of Atreus drew his sword, and drove at the projecting part of his helmet, but the sword fell shivered in three or four pieces from his hand, and he cried, looking towards Heaven,"Father Jove, of all gods thou art the most despiteful; I made sure of my revenge, but the sword has broken in my hand, my spear has been hurled in vain, and I have not killed him."
阿特柔斯之子拔出柄嵌银钉的铜剑,高举过头,奋力劈砍对手的盔脊,却被撞顶得七零八落,脱离了手的抓握。阿特柔斯之子长叹一声,仰面辽阔的天穹:"父亲宙斯,你的残忍神祗中谁也不可比及!我想惩罚亚历克山德罗斯的胡作非为,但我的铜剑已在手中裂成碎片,而我的枪矛也只是徒劳地作了一次扑击,不曾把他放倒!"

If one square inch of copper is used as a heat dissipator for the TO-252, the J-A drops to approximately 50C/W. The SOT-223 package has a J-A of approximately 125C/W when soldered down to a minimum sized pattern (less than 0.1 square inch) and approximately 70C/W when soldered to a copper area of one square inch.
如果一平方英寸的铜是作为的TO - 252热消使用时,司法机构政务长下降到大约50 / W的的SOT - 223封装具有的司法机构政务长大约125C / W的焊接时下跌不到0.1平方英寸的最小尺寸为1型和大约70 / W型焊接时,一铜一平方英寸面积。

A new recovery technology of solid waste was made which is from furfuryl alcohol production by furfural hydrogenization. When the solid waste is placed in a vacuum drying box, and is under lower negative pressure and at 130℃, the organic materials in solid waste can be distilled and then returned to the refining workshop to produce qualified furfuraldehyde and furfuryl alcohol. The remainder is mixed with soda ash and roasted in a reverberating furnace. The sodium chromate can be obtained by leaching. Rough cupric oxide is dissolved in nitric acid and cupric nitrate is obtained. A new catalyst was prepared by the above sodium chromate and cupric nitrate and used in furfuryl alcohol production.
将糠醛液相加氢生产糠醇产生的废渣置于真空干燥箱中,在较低的负压状态下保持130℃的温度,蒸馏回收废渣中的有机物,返回糠醇精制车间获得合格的糠醇与糠醛产品;剩余的固体废弃物与纯碱混合,在反射炉中焙烧,浸取获得铬酸钠水溶液;最后剩下的粗氧化铜溶于硝酸得到硝酸铜溶液;将铬酸钠溶液、硝酸铜溶液按一定比例混合,加入氨水搅拌,分离出的沉淀经传统方法焙烧活化、造粒制得新催化剂,回用于糠醛液相加氢生产糠醇。

Deiphobus then came close up to Idomeneus to avenge Asius, and took aim at him with a spear, but Idomeneus was on the look-out and avoided it, for he was covered by the round shield he always bore- a shield of oxhide and bronze with two arm-rods on the inside.
其时,德伊福波斯,怀着对阿西俄斯之死的悲痛,逼近伊多墨纽斯,投出闪亮的铜枪,但后者紧盯着他的举动,弯身躲过飞来的枪矛,蹲藏在溜圆的战盾后面――此盾是他常用之物,坚实的牛皮,箍着闪光的铜圈,安着两道套把。

The performance and mechanism of corrosion inhibitions of POCA were studied bymethods such as weight-loss, electrochemistry, EDS, XPS and quantum chemistry. It isfound that POCA is cathodic corrosion inhibitor, having synergistic effect with HEDP andZn~(2+). The P and O atoms of phosphono have important electron density contribution toHOMO orbital and the electron gross orbital population is bigger than 1, so it is easy toform absorbing location between phosphono and metal resulting in good corrosioninhibition on mild steel.
通过利用失重法、电化学方法、扫描电镜、X光电子能谱、X-射线能谱和量子化学方法研究膦酰基羧酸的缓蚀性能及其机理,发现POCA是一种阴极型缓蚀剂,与HEDP、Zn~(2+)具有优良的协同增效作用;POCA分子中的膦酰基基团的P原子和O原子对HOMO轨道电荷密度贡献较大,且其轨道电子布居数均大于1,因此比较容易通过膦基与金属形成吸附位而对碳钢具有良好的缓蚀作用;对铜合金具有一定的腐蚀作用,但腐蚀作用比HEDP等有机膦药剂要小得多,同时与BTA具有优良的相容性,添加1mg/L的BTA则可以有效地防止铜合金的腐蚀。

The metal ions of the dinuclear copper complex of [Cu_2_2Cl_4] are linked by two N~1,N~2 1,2,4-triazole bridges,and the central Cu ions have distorted trigonal bipyramid geometries. The central Cu ion of [CuL22]·H2O has a centrosymmetric and distorted tetragonal-octahedral geometry. The metal ions of the dinuclear manganese complex of [Mn_2L_2_2Cl_2(H_2O)_2] are bridged by two chlorine atoms, and the central Mn ions have distorted tetragonal-octahedral geometries. Part III.

Results show that Pb enrichment factors varied from 1.0~1.8 in the cultural layers, and were not quite high. However, with the history going on from the Dawenkou Culture to the Longshan Culture, the Pb enrichment factor displayed an obvious rising trend, which indicated that the Pb in the cultural layers was probably associated with the development of metallurgic activities in the middle stage of the primitive society. From 5 050 cal a BP to 4 000 cal a BP, China underwent Stone Age, Chalcolithic Age and Bronze Age in sequence. Pb dust in the atmosphere increased with intensifying utilization of copper resources, which was probably the main cause of the rising enrichment factor in the cultural layers.
但是随着时间的推移,从大汶口文化到龙山文化,Pb的富集系数有明显逐步上升的趋势,表明遗址剖面中的Pb很可能与原始社会中期发展起来的冶金活动有关。5 050~4 000 cal a BP间,中国先后经历了石器时代、铜石并用时代,到最后进入青铜时代,这个过程中铜资源利用越来越多导致产生的大气粉尘铅越来越多,很可能是YC1剖面中Pb富集系数逐步增长的主要原因。

Hector's round shield showed in the front rank, and as some baneful star that shines for a moment through a rent in the clouds and is again hidden beneath them; even so was Hector now seen in the front ranks and now again in the hindermost, and his bronze armour gleamed like the lightning of aegis-bearing Jove.
赫克托耳,挺着溜圆的战后,站在队伍的最前排,像一颗不祥的星宿,在夜空的云朵里露出头脸,闪烁着耀眼的光芒,然后又隐入云层和黑夜,赫克托耳时而活跃在队伍的前列,时而又敦促后面的兵勇们向前,铜盔铜甲,闪闪发光,像父亲宙斯,带埃吉斯的天神投出的闪电。
