氧气

Tonglu: composite or pure copper radiator heating system in the use of one-pipe is dangerous, because one-pipe system, high-speed hot water would have a copper corrosion, should carefully chosen.

然而由于钢制散热器怕水中的氧气，它对供热系统要求很严格，在不安全的系统中会出现腐蚀（腐蚀点大部分在管壁上，而不在焊接部位）；而另外一个事实是，目前我们国内的许多采暖系统还不是很完善，虽然国家对采暖水质早有规定，但仍有许多物业不能按标准执行。

The ratio of oxygen to electric steel and the recycling rate of scrap differ in a wide range.

氧气电炉炼钢所占的比例以及垃圾回收率在很大程度也有不同。

With the oxygen ratio increasing, the reflectivity of the as-deposited films decreased, and optical band gap increased.

随着氧气分压比的增大，沉积态薄膜的反射率下降，禁带宽度增大。

产氧量与空气量之比约为15－18，氧气收得率约为25％～30％。

The effects ofreaction temperature, reaction time, BPO and St concentrations,Oxygen on grafting ratio were studied.

研究了反应温度、反应时间、BPO浓度、苯乙烯浓度以及氧气对接枝率的影响。

The influence of RF power and oxygen ratio on the grain size, the residual stress and optical properties was investigated by X ray diffraction and transmission spectra.

通过XRD和透射光谱研究了射频功率和氧气比例对ZnO薄膜的晶粒尺度、应力状态和光学性能的影响。

The results show that the crystallization of the ZnO film deposited with sputtering power(100W) and oxygen ratio(60%),can obtain its best c-axis orientation and crystallization and tension stress of the film reach.

研究结果显示，射频功率在100W下制备的ZnO薄膜，当氧气比例为60%时，能获得单一c轴择优取向和最小半高宽，压应力最小的薄膜，即结晶性较好的薄膜。

Dianmond films were deposited on Al2O3 ceramic substrates by oxygen-acetylene flame, the morphologics and their distribution of deposited films on the substrate surfaces were also observed.

用氧气-乙炔火焰法在氧化铝陶瓷片上沉积出了金刚石薄膜，并观察了薄膜的形貌结构及其在基片上的分布规律。

A new board shaped ozone generator is proposed to efficiently generate ozone. This paper introduces the generator design based on surface discharge theory in the nonuniform electric field.

臭氧是氧气的同素异形体，与常见的消毒剂氯气相比，臭氧的灭菌速度是氯气的600～3000倍，而且，臭氧的高效杀菌灭毒本领和不留二次污染性历来受到人们的青睐。

Some of you may remember a piece of news in July where a team of Universiti Sains Malaysia researches led by Dr Syamsul Rizal Abd Shukor came up with a way to produce hydrogen in a system compact enough to be fitted into a car.

&Hydroxene&的氢氧辅助燃料技术是在油箱以外，添装一个水箱。当汽车引擎发动时，水箱内的水将被输送到一个金属处理器内，把水中的氢气和氧气分解开来。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
