The navy's notice suggests, though, that boron is back.

Boron does not, however, introduce the quest for the Grail that would come later.

然而，鲍伦并没有介绍后来对圣杯的探索。

The only way you can get boron down there, is by the foundering of the ocean crust.

So far, the researchers involved have managed to produce one that is 40% boron and yet burns more or less completely.

到目前为止，参与研究的研究人员已经成功制造出了一种有40%硼且几乎可完全燃烧的燃。

Super hardened boron, sharpened with a CO2 laser.

- 超硬硼，使用 CO2 激光打磨。

Over millions of years, the boron continued to move deep underground.

数百万年来，硼继续向地下深处移动。

Scientists already knew these diamonds received their blue color from the element boron.

科学家们已经知这些钻石的蓝色来自硼元素。

Its fuels are boron (five protons and six neutrons) and ordinary hydrogen, both plentiful.

它的燃是硼（五个质子和六个中子）和普通的氢，两者都很丰富。

An implanter then accelerates boron or phosphorus ions and slams them into the patterned openings.

然后，离子注入机加速硼或磷离子，并将它们打入图案化的开口中。

However, ion implanters only add around one atom  of phosphor or boron for every 10,000 atoms of silicon.

然而，离子注入机每 10,000 个硅原子仅添加约 1 个磷原子或硼原子。

America's air force experimented in the 1950s with stuff nicknamed zip fuel, which was laced with compounds of boron called boranes.

美国空军在20世纪50年代试验了一种叫做拉链燃(高型能的飞机燃)的东西，这种燃有硼烷的化合物。

Boron additives in rocket fuels also failed. The combustion process involved proved unexpectedly complex, and the promised additional energy was not forthcoming.

火箭燃中的硼添加剂也失败了，其中涉及的燃烧过程出乎意地复杂，而且所承诺的额外能量并没有到来。

Boron does, though, burn like billy-o, generating a bright, green flame and releasing about 40% more energy per kilogram than conventional aviation fuel.

不过硼确实可以快速燃烧，产生亮的绿色火焰，每千克要比传统航空燃多释放约40%的能量。

Boron is an interesting element. It is one of the few that I have actually made myself when I was at school.

硼是一种有趣的元素。这是我在学校时实际制作的为数不多的作品之一。

The only way you can get boron down there, is by the foundering of the ocean crust. 24 They literally sink deep into the mantle.

在那里获得硼的唯一方法是通过沉没的洋壳。 24 它们真的沉入地幔深处。

Compounds of boron feature in washing powders and cleaning products (" borax" ), antiseptics and water softeners, and also as additives in fibreglass, but such roles are humdrum.

硼化合物用在洗衣粉和清洁产品(“硼砂”)、防腐剂和水软化剂中，也可作为添加剂的玻璃纤维，但这些作用是单调的。

The project's objective is to " determine a form of boron or a boron-based chemical pathway that leads to implementation of boron in energetic compounds, especially fuels (solid and liquid)" .

该项目的目标是“确定一种硼的形式或一种基于硼的化学途径，使硼在高能化合物，特别是燃(固体和液体)中得以实现”。

After that, for days, thousands of tons of clay, sand, boron, and dolomite, were dropped by helicopter into the burning reactor to quell the fire, but also to try and prevent the spread of radiation.

在那之后的几天里，成千上万吨的粘土，沙子，硼和白云石，被直升机抛进燃烧的反应堆中以扑灭大火，并试图阻止辐射的扩散。

These tools use the photomask stencil to bombard the unmasked  regions with phosphor, boron, or other elements in order to make the P and the N regions required  to form the transistors themselves.

这些工具使用光掩模模板，用磷、硼或其他元素轰击未掩模的区域，以制造形成晶体管本身所需的 P 区和 N 区。
