那么让我们以氰化氢为第一个例子。
水蒸气的加入会抑制氰化氢的产率。
The addition of steam inhibits the production of hydrogen cyanide.
本文主要对氰化氢气体在火灾烟雾中的毒性及其抗氰救治措施进行研究。
This paper was aimed to study the toxic mechanism and anti-cyanide measures to hydrogen cyanide (HCN) in fire smoke.
肠溶物的单向流动可以防止有毒物质的积累,使臭腹腺蝗成功耐受木薯叶中的氰化氢。
One-way movement of the gut contents prevents accumulation of toxic substances to injurious levels, enabling the insect to favourably tolerate hydrogen cyanide in cassava leaves.
那么,请大家来告诉我,并且记住它,你认为氢,碳和氮中哪个原子,应该在氰化氢的中间呢?
So, why don't you go ahead and tell me, keeping that in mind, which atom in terms of h c or n would you expect to be in the center of hydrogen cyanide?
已确定二手烟的烟雾中含有超过7千种化学物质,其中至少250种是有害的,比如氰化氢、一氧化碳和氨。
Among the more than 7,000 chemicals that have been identified in secondhand tobacco smoke, at least 250 are known to be harmful, for example, hydrogen cyanide, carbon monoxide, and ammonia.
它还可以防止一氧化碳,烟雾,氰化氢,二氧化硫,其他气体,颗粒,烟雾,烟尘,氨,氯,磷,和辐射热的危害。
It also protects against carbon monoxide, smoke, hydrogen cyanide, sulfur dioxide, other gases, particulates, fumes, soot, ammonia, chlorine, phosphine, and radiant heat.
斯皮策探测到在和我们太阳类似的黄色恒星周围的尘埃盘中有一种原始生命分子-氰化氢,但在更冷的、质量更少的微红色恒星周围却没有。
Spitzer detected a prebiotic molecule, called hydrogen cyanide, in the disks around yellow stars like our sun, but found none around cooler, less massive, reddish stars.
斯皮策探测到在和我们太阳类似的黄色恒星周围的尘埃盘中有一种原始生命分子-氰化氢,但在更冷的、质量更少的微红色恒星周围却没有。
Spitzer detected a prebiotic molecule, called hydrogencyanide, in the disks around yellow stars like our sun, but found nonearound cooler, less massive, reddish stars.
考察了一元铂与二元铂铑两种贵金属催化剂对氰化氢的催化燃烧效果,探讨了温度、氰化氢浓度、空气含量及气体空速等因素对脱除氰化氢的影响。
The catalytic combustion of hydrogen cyanide was studied separately in presence of two kinds of noble metal catalysts, i. e. , unary platinum and dualistic platinum-rhodium.
这看起来整洁了不少,如果我们把氰化氢的路易斯结构画成这样的话,这样我们就有氢与碳之间的单键和碳与氮之间三键,然后还有一对孤对电子在氮这里。
So it looks a lot less messy if we just draw our Lewis structure like this for h c n, where we have h bonded to c triple bonded to n, and then a lone pair on the nitrogen there.
