查询词典 iron earth

A steel plate having a tensile strength of at least about 930 MPa (135Ksi), a toughness as measured by Charpy V-notch impact test at least about 120 joules (88 ft-lb), and a microstructure comprising at least about 90 volume percent of a mixture of fine-grained lower bainite and fine-grained lath martensite, wherein at least about 2/3 of said mixture consists of fine-grained lower bainite transformed from unrecrystallized austenite having an average grain size of less than about 10 microns and comprising iron and specified weight percentages of the additives: carbon, silicon, manganese, copper, nickel, niobium, titanium, aluminum, calcium,rare earth metals, and magnesium, is prepared by heating a steel slab to a suitable temperature; reducing the slab to form plate in one or more hot rolling passes (10) in a first temperature range in which austenite recrystallizes; further reducing said plate in one or more hot rolling passes (10) in a second temperature range in which austenite does not recrystallize, quenching (12) said plate to a suitable quench stop temperature (16); and stopping said quenching and allowing said plate to air cool (18) to ambient temperature.

I suspect, in honesty, my initial interest was based on a private image of streams of unsuspecting eastbound motorists in the American plains states plunging over the edge of a sudden 4,000-mile-high cliff running between Central America and the North Pole, but gradually my attention did turn in a more scholarly manner to the scientific import of the drawing and the realization that the Earth consisted of discrete layers, ending in the center with a glowing sphere of iron and nickel, which was as hot as the surface of the Sun, according to the caption, and I remember thinking with real wonder:"How do they know that?"

坦白讲，我怀疑自己最初对那幅画的兴趣仅源于脑海中的一幅画，里边一群意志坚定的人驾车东去，要穿越横亘在中美与北极之间的一道深四千公里的悬崖。但后来开始慢慢的以一种学术眼光来研究这幅插图背后的科学含义。并意识到地球是由分离的层组成，最里边是由铁和镍构成的发红的球心。图片旁边的说明文字解释说，这个球心的温度同太阳表面一样高。我仍记得当初十分好奇的想知道，他们是如何得知这一切的。
