文章根据天然气发动机的具体参数和特性，探索电控喷射CNG发动机在燃料喷射、点火能量和稀燃等方面的控制规律，确定最优的控制参数，开展了喷射定时、点火能量及稀薄燃料等参数对发动机性能影响的试验研究工作，并根据试验结果分析，得出了以下结论：电控喷射WT615CNG发动机燃料喷射提前角要小些为宜

PAHs ratios are used to identify the source of PAHs, the result showed that the major source of 16 PAHs in Urumqi Xinshi district was coal-bustion and vehicle discharges . Mercury in TSP samples were digested by aqua regia and analyzed by AFS analyzer .The results showed that : the concentration of mercury was 0.869-1.91 ng m-3.Compared with other cities in the rest of the world , the concentration of mercury was very high. The concentration of mercury in heating season was lower than that in no-heating season.

对大气颗粒物样品中的汞，采用王水于特弗龙消解罐中加热消解的方法进行处理，稀酸定容后采用原子荧光光谱法对样品中的汞进行测定，测定结果为。869-1.91 ng m-3，与国外城市相比较高；实验测得非采暖期乌鲁木齐大气颗粒物汞浓度的均值高于采暖期颗粒物中的汞浓度，其原因可能是由于随着非采暖期温的升高，长期积累在土壤、水体环境中的汞向大气中释放，附着在颗粒物上，过了燃煤的影响。

The approach of preparation method is that, first, blend yttria into hot aquafortis, add silicone grease chemical compound after reaction, cool it to form gel. Second, heat the gel for 1-48 hours to acquire solid fruitage. Third, igloss the fruitage in reducing gas for 1-48 hours. Forth, add anorg and then igloss it in reducing gas for 1-48 hours in the temperature between 800-1600 degree.

它的制备方法，包括以下步骤：1将氧化钇溶入热浓硝酸中，反应后加入硅酯类化合物，恒温形成凝胶；2凝胶加热1-48小时，得到固相产物；3在还原气氛中灼烧1-48小时；4加入无机盐，在800-1600℃范围内，还原气氛中灼烧1-48小时；5稀酸洗涤，干燥后得到稀土激活Y2SiO5荧光粉。

But in the process of ion exchange, xylose molecular is easily converted into arabinose because of catalytic isomerization, which results in the decrease of its purity and difficulty of crystal.

木糖是一种在化工、食品等领域有着广泛用途的五碳糖，工业生产是用稀强酸将玉米芯中含有的大量多缩戊糖分解为单个的木糖分子，然后通过离子交换除盐、脱色，精制提取，但在强碱离子交换柱中，木糖分子容易被部分催化异构转化为阿拉伯糖，使得木糖纯度下降，结晶困难。
