After lighting the firearms set off,the solid nitrogen grain is quick to gasify,the nitrogen of large quantity nitrogen spirit blows to rise the air sac immediately,and in the mighty impact dint under,the air sac hurtles to open the cover on the steer device but the safety launche.

在正驾驶位的气囊装在方向盘的中间位置，副驾驶位的安全气囊安装在正前方的平台内部，在意外发生的瞬间可以有效的保护驾驶员和副驾驶位乘员的头部和胸部，因为正面发生的猛烈碰撞会导致车辆前方大幅度的变形，而车内乘员会随着这股猛烈的惯性向前俯冲，造成跟车内构件的相互撞击，另外车内正驾驶位置的安全气囊可以有效的防止在发生碰撞时方向盘顶到驾驶者的胸部，避免致命的伤害。

Third, most magnesium alcoholates are prepared by alcoholysis.The process is based on the exchange of alkoxide groups of a metal alcoholate in the presence of an alcohol other than the alcohol corresponding to the original alkoxide,i.e.on the alcoholysis of a metal alkoxide with a different alcohol. Primary alcoholates can be prepared by this process,such as magnesium di-n-propanolate,magnesium di-n-butanolate,magnesium di-isobutanolate.

该方法适用于较高沸点的伯醇的醇镁化合物，例如正丙醇镁、正丁醇镁、异丁醇镁等，但是用醇解法制备出的叔丁醇镁，其纯度只有80％，这是由于叔丁醇具有较大的空间位阻效应，阻碍了醇交换的进一步进行，并且叔丁醇沸点与甲醇相差不大，使得甲醇难以快速蒸出，只能得到一种混合醇盐产物。

The results showed:(1) Through glycosylated orthogonal test, When the substrate concentration is 1:2, glycosylated temperature is 60℃, the enzyme dosage is 0.5%and glycosylated time is 6 hours, glycosylating was at best, and the sugar concentration was 33%(2) through fermentation orthogonal test, when adding the yeast is 2.0%, proportion of Rhodiola and glutinous rice is 1:1, the temperature is 28℃, and fermentation time is seven days, alcoholicity of the wine was the highest and sensory evaluation was the best..

本文立足加工高品质的红景天糯米保健酒，主要对糖化条件，发酵工艺参数的确定，后发酵温度的确定，稳定性试验，膜过滤试验条件，营养成分分析等方面进行系统的研究，结果表明：(1)通过糖化正交试验，在底物浓度1∶2、糖化温度60℃、酶用量0.5％、糖化6h时糖化效果最好，糖液浓度33％；(2)通过发酵正交试验，在酵母添加量2.0％、红景天糯米比1∶1、发酵温度28℃、发酵时间7天生成的酒度最高，感官评价最好；(3)通过后发酵试验，选择10～15℃温度下后发酵，酒体澄清，感官评价最好；(4)从对红景天糯米酒稳定性分析中得知：酒体在低于-6℃时略有絮状物出现，酒体混浊沉淀的主要原因可能是蛋白质。

Catalytic effect of ionic liquids to isobutane and butene alkylate reaction was studied,composition of ionic liquids,isobutane and butene mole compares factors to the alkylate reaction influence was reviewed.

研究了离子液体对异丁烷与正丁烯烷基化反应的催化作用，考察了离子液体组成、异丁烷与正丁烯物质的量比等因素对烷基化反应的影响。

Results: The refraction results of the Allegretto Wave Analyzer were very unstable. The spherical, cylinder diopter and the axis of the cylinder varied greatly. The refractive errors were large while the refractive errors were little by the subjective refraction examinations. During the wavefront examination, spots of the laser matrix were blurring, and the reproducibility was not good. Wavefront analyses showed that the Array pseudophakic eyes had relative large coma while the patients had no obvious symptoms.

研究结果：像差分析仪检测得的屈光度结果十分不稳定，球镜度、柱镜度、散光轴都变化很大，可重复性差，检测的屈光不正度数较大，而主觉验光时，患眼的屈光不正度数较低。5只眼的光学矩阵的测量点均非常模糊，且测量结果的可重复性较差，像差分析显示，Array人工晶状体有很大的第三阶彗差，但患者的自我感觉良好。
