The results showed that desulphurization rate was apparently influenced by lance level while it was not obviously influenced by inclination of lance and bellmouth height; desulphurization rate was becoming slow if carrier gas flow was too low (Q=25Nm~3/h) and was not obviously influenced if carrier gas flow was over some value.

载气流量过小时(如Q=25Nm~3／h)会明显降低镁脱硫速率，载气流量增大到一定值后、再继续增大时对脱硫速率不会产生明显影响。喷枪夹角和喷枪喇叭口高度的改变对脱硫速率没有明显影响。

Under the steady state assumption, equilibrium concentration of benzo pyrene in air is very low (1. 3×10〓mol/m〓) with almost all of the chemical absorbed on particles.

稳态条件下，气相中苯并芘的平衡浓度相当低，仅1.3×10〓mol/m〓，且在气相中几乎所有的物质都吸附在颗粒物上，以气态形式存在的量微不足道。

Results: BIO-1211 aerosol at 1, 3 and 10 mg/ml significantly inhibited the changes in lung resistance and lung dynamic compliance after antigen challenge in the sensitized rats in a dose-dependent manner, BIO-1211 at 25, 50, 100 and 200μg/ml inhibited the fibronectin-induced neutrophil adhesion by 23.5%, 24.6%, 61.4% and 58.1%, respectively, and serum-induced adhesion by 29.9%, 35.9%, 35.3% and 15.4%, respectively. Inhalation of 10mg/ml BIO-1211 did not show any protection against histamine and actetylcholin-induced bronchoconstriction.

结果：给大鼠气雾吸入BIO-1211 (1、3、10mg/ml)呈剂量依赖抑制致敏大鼠抗原攻击引起RL的升高和Cdyn降低；BIO-1211(25、50、100、200μg/ml)明显抑制纤维黏连蛋白和血清诱导的中性粒细胞黏附反应，其抑制率分别为23.5%、24.6%、61.4%、58.1%和29.9%、35.9%、35.3%、15.4%；但BIO-1211 (10 mg/ml)给豚鼠气雾吸入不能抑制乙酰胆碱和组胺诱导的药物性哮喘。

The results showed that ascorbic acid oxidase activity in the flesh of 'brumal Jujube' became significantly higher than in pericarp with the development of maturity; but these activities of peroxidase , Polyphenoloxidase and phenylalanine ammonia-lyase in flesh were lower than in pericarp . During the development from green to half-red then to red, the lignin and fibre contents in pericarp gradually increased higher than in flesh; ethanol content also increased , acetaldehyde content reached to a peak during the red maturity stage and then declined.

随着贮期的延长，冬枣果肉中乙醇和乙醛含量增加，乙醇发酵关键酶的活性逐渐升高；气调贮藏延缓了果实中乙醇和乙醛的积累，抑制了PDC和ADH的活性，显著提高了果实的贮藏品质；说明气调贮藏延缓了果实的乙醇积累；但CA_1比CA_2促进果实乙醇积累的作用较明显，表明冬枣对高浓度CO_2较敏感，这可能是枣果实不耐高CO_2的原因之一。

In this paper, using bupleurum as an example, a method of obtaining chromatograms of volatile oil in crude drugs by using gas chromatography and converting the data to retention index and percentage area in order to get the fingerprint of each sample was presented.

本文以生药柴胡为例，介绍了以气相色谱法获得含挥发油生药的气相色谱数据，并换算成保留指数和归一化峰面积，得到每一个样品的指纹图，将未知样品与标准样品的指纹图相比较，从而鉴别未知样品的方法。

The invention relates to a processing method of preventing frostbite and restarting of hydrogen electric pile, whose characteristic lies in the treating processes includes: When the electric pile turns off, the unsaturated fuel gas or the nitrogen, through the circle boast to clean the dissociate water; drying the MEA film module to keep the water content below the stipulated temperature which does not ice up; then the recycle gas through a wet exchanger to dry and the dried gas is continue used in the dry pile step; when restarting the electric pile, the recycle gas must heats then through the pile to elevate the temperature, then heats the fuel gas and the oxidant of the gas source, through the weting of the wet exchanger enters to the calefactive pile, enhances the wet step of the film module in the pile, starts the power output of the pile.

本发明涉及一种氢电堆的防冻和重新启动时的处理方法，其特征在于处理过程包括：电堆停机时，将水蒸气不饱和的燃料气体或氮气，通过循环吹扫除去电堆的游离水；干燥其中的MEA膜组件，使膜组件含水量降低到规定低温下不结冰的程度；而后再令循环气体通过一个湿交换机将循环气体干燥，以及被干燥后的循环气体继续用来干燥电堆的步骤；在电堆重新启动时，须将循环气体加热后通过电堆，使电堆升温，然后再将气源的燃料气及氧化剂加热，通过湿交换机加湿后进入已升温的电堆，提高电堆中膜组件的湿度的步骤，开始电堆的功率输出。
