卤素

Cesium and water, and even and low temperature to - 116 degrees of ice can occur with violent reaction, also can generate stable halogen halide, this is because it is caused by large radius of ions.

铯和水，甚至和温度低到-116℃的冰均可发生猛烈反应，与卤素也可生成稳定的卤化物，这是由于它的离子半径大所带来的特点。

Distribution of illumination of metal halide lamp and halogen lamp were analyzed and compared.

金属卤化物灯和卤素灯在这一光照度的诱集范围之比为1 66∶1。

Several transient compounds were synthesized by the homo- and heterogeneous reactions of reactive halogen compounds, In-situ ultraviolet photoelectron spectroscopy and photoionization mass spectroscopy as well as theoretical calculations were used to study their molecular structures, stability and molecular orbital properties, their electronic structures and geometric structures were obtained for the first time; Simultaneously, the electronic structure and thermal dissociation of acetyl peroxynitrate and trifluoroacetyl peroxynitrate which have great importance in the atmospheric chemistry were studied; The substituent effects of series of halopyridines and halothiophenes were studied by the ultraviolet photoelectron spectroscopy method for the first time. The atmospheric chemical reaction between peroxyacetyl radicals with IO radicals as well as the dissociation of the most stable isomer of CH3COIO3 were calculated by density functional theory, it was found that the CH3COOIO2 isomer may be act as a new reservoir of inorganic iodine in the stratosphere.

通过活性卤素的系列均相与非均相化学反应合成了几种瞬态物种，采用原位紫外光电子能谱和光电离质谱结合量子化学理论计算对化合物的分子结构、稳定性以及分子轨道特性进行了研究，首次获得了这些物种的电子结构和几何结构的信息；同时研究了大气中有重要作用的乙酰过氧硝酸酯和三氟乙酰过氧硝酸酯的电子结构性质及热解过程；采用紫外光电子能谱手段首次研究了系列卤代吡啶和噻吩的取代基效应；通过量子化学理论计算研究了乙酰基过氧自由基与IO自由基的大气化学反应及其最稳定异构体CH3COOIO2的解离，发现该物种可能是无机碘化合物在平流层中的储库物种。

In comparison with Halogen lamps: lumen, color temperature and life cycle is much higher.

与一般的卤素灯对比：流明、色温、寿命都要高于卤素灯。

The halogens are five non-metallic elements found in group 17 of the periodic table.

卤素是ⅦA族中的5钟非金属元素，卤素的意思来源于希腊语halos和gennan两个词。

Exposing the skin for chlorine or other halogens, or medicines containing halogens.

暴露皮肤氯或其他卤素，或含有卤素。

Exposing the skin for chlorine or other halogens, or medicines containing halogens.

为皮肤暴露氯气或其它卤素或含卤素。

From such considerations,it is obvious that inert gases should be less reactive than are halide ions,but their compounds should show even higher reactivity than the halogens .

从这样的考虑，很明显，惰性气体应小于反应比卤素离子，但他们应该表现出的化合物，甚至高于卤素反应。

The discharge space (13) is filled with mercury as light-emitting material, rare gas such as xenon, and halogen gas for halogen cycle.

放电空间(13)以水银填充当发光物质，稀有气体例如氙，和卤素循环的卤素气体。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
