查询词典 off the spot

A series of spot welding technology and joint tensile-shear tests for uncoated low carbon, electroplated and two kinds of hot dipped zinc-coated steels were made to improve the quality of spot welding joint for zinc-coated steels. The test results were analyzed with computer regressive method. The effects of welding current or time on nugget diameter or joint tensile-shear strength and critical curves in splash generation for spot welding were obtained.

Because of the quality of ore, blast furnace characteristics of the relationship between medium-sized steel enterprises mainly long association mining, we simulated the second quarter, compared with the spot price of Australian mine co-lowest out of 10%-20%, but assuming that Australian iron ore price agreement long in the third quarter rise about 23%, sea freight and ore spot prices remain unchanged in the next six months, then we simulated the third quarter than the spot price of Australian mine co-7.8% higher price.

因矿石品质、高炉特点等关系，大中型钢企主要采用长协矿，我们模拟的二季度澳矿长协价较现货价低出10%-20%，但如果假设澳矿三季度长协价再涨23%，现货海运费和矿价在未来六个月均保持不变，那么我们模拟的三季度澳矿长协价较现货价高出7.8%。

The results show that the plasticity zone and dynamically quiescent layer become fine equiaxed recrystallisation under the thermo-mechanical effect, the grains in the heat-affected zone grow up because of the effect of friction heat. When the rotation speed is 2 500 r/min and the welding time is 12 s, good joint is achieved, and the tensile shear strength of the joint reaches 9.24 kN. The tensile shear strength of spot increases with increasing tool rotation speed, with increasing welding time, the strength increases first, while then reduces. The microhardness of plasticity zone is high, but is slightly lower than that of the base metal, the minimum value of microhardness is in the heat affected zone. When the energy input of joint is high, the fracture type of spot is mode Ⅰ, and the tensile shear strength is high; on the contrary, when the energy input of joint is less the fracture type of spot is mode Ⅱ, and the strength is low.

结果表明：塑性区和动态静止层的晶粒在热和力作用下发生动态再结晶形成细小的等轴晶，热影响区的晶粒在摩擦热作用下长大变粗；搅拌头旋转速度为2 500 r/min，焊接时间为12 s时，可以获得力学性能较好的焊点，焊点的剪切强度达到9.24 kN；焊点的剪切强度随搅拌头旋转速度的增大而增大，随焊接时间的延长先增大后减小；塑性区的显微硬度较高，但略小于母材，接头显微硬度的最小值分布在热影响区；焊点热输入量较多时，接头为Ⅰ型断裂，焊点的剪切强度较高；焊点热输入量较少时，接头为Ⅱ型断裂，焊点的强度较低。

And now I began to think sedately; and, upon debate withmyself, I concluded that this island (which was so exceedinglypleasant, fruitful, and no farther from the mainland than as I hadseen) was not so entirely abandoned as I might imagine; thatalthough there were no stated inhabitants who lived on the spot,yet that there might sometimes come boats off from the shore, who,either with design, or perhaps never but when they were driven bycross winds, might come to this place; that I had lived therefifteen years now and had not met with the least shadow or figureof any people yet; and that, if at any time they should be drivenhere, it was probable they went away again as soon as ever theycould, seeing they had never thought fit to fix here upon anyoccasion; that the most I could suggest any danger from was fromany casual accidental landing of straggling people from the main,who, as it was likely, if they were driven hither, were hereagainst their wills, so they made no stay here, but went off againwith all possible speed; seldom staying one night on shore, lestthey should not have the help of the tides and daylight back again;and that, therefore, I had nothing to do but to consider of somesafe retreat, in case I should see any savages land upon the spot.

后来的事实也证明，他既是一位虔诚的基督徒，又是一位知恩图报的朋友。他的这种品质实在使我非常满意。可是，在我对他的疑惧没有消除之前，我每天都要试探他，希望他无意中会暴露出自己的思想，以证实我对他的怀疑。可是我却发现，他说的每一句话都那么诚实无瑕，实在找不出任何可以让我疑心的东西。因此，尽管我心里很不踏实，他还是赢得了我的信任。在此期间，他一点也没有看出我对他的怀疑，我也没有根据疑心他是在装假。有一天，我们又走上了那座小山。但这一次海上雾蒙蒙的，根本看不见大陆。我对星期五说："星期五，你不想回到自己的家乡，回到自己的部族去吗？"他说："是的，我很想回到自己的部族去。"我说："你回去打算做什么呢？你要重新过野蛮生活，再吃人肉，像从前那样做个食人生番吗？"他脸上马上显出郑重其事的样子，拼命摇着头说："不，不，星期五要告诉他们做好人，告诉他们要祈祷上帝，告诉他们要吃谷物面包，吃牛羊肉，喝牛羊奶，不要再吃人肉。"我说："那他们就会杀死你。"
