College of Chemical Engineering, Guizhou University, Guiyang Guizhou 550003, ChinaAbstract:In the course of polymerization of tung oil modified phenol aldehyde resin, by adding some SiO2 nanometer particles which have been scattered, compound modified heat-curable NTPF was made.

在桐油改性酚醛树脂的聚合过程中，添加经过分散的SiO2纳米粒子，制备成复合改性的热固性NTPF，经过SETARAMTG-DSC92-16热分析仪测试NTPF的耐热性有明显的提高。

In view of solving the pollution problem of waste alkali liquor in oil refineries, 5 optimized strains were screened and domesticated from refinery sludge for the degradation of alkaline wastewater. It can be seen that the degradation performance of these 5 strains was significant by comparing the chemical oxygen demand value.

针对炼油厂高浓度废碱液污染大、难处理的问题，从污泥中经过驯化分离，筛选出5株用于废碱液降解的优势菌，经过对5株菌降解化学耗氧量的比较，优势菌对废碱液的降解效果明显。

After pumps passes through the long time movement, the friction balancing a set and balancing a ring wears away , gap b enhances subsequently, the amounts sealing off axial to fleeing increase machinery unceasingly.

经过水泵经过长时间的运动，摩擦平衡一套和平衡戒指戴了，差距b增强随后，数额封锁，以逃避轴向机械不断增加。

So because of that, they need to take that bitumen through one more process so that it can be refined, and they take it through a process that will transform it to what's called synthetic crude oil or synthesised bitumen.

正因为如此，他们就需要让这些沥青再经过一道加工，这样才适合提炼。经过这道工序后，沥青就转变成了合成原油，或者叫合成沥青。

It's black-red quality, enhanced through the wax polish and through maturing, may have brought it into fashion as a substitute for the costly red sandalwood.

经过上蜡和经过年久成熟，其黑红色质地更加美观，可能使这种木材作为贵重紫檀木的替代品得以流行起来。

Papers in the experimental part of our literature considered on the basis of the experimental exploration, and podophyllotoxin intermediates with the structural characteristics of a simple pepper aldehyde as the starting material,α,β-unsaturated carbonyl compounds are selective reduction lithium aluminum hydrogen reduction reaction as the key steps to have the Knoevenagel condensation, peracetic acid epoxy between chlorine and alkaline hydrogen peroxide epoxy, DCC condensation esterification reaction of the three podophyllotoxin intermediates.

论文实验部分我们在综合考虑文献的基础上，经过实验摸索，并结合鬼臼毒素中间体的结构特点以简单的胡椒醛为起始原料，对α，β-不饱和羰基化合物具有选择性还原的锂铝氢还原反应为关键步骤，先后经过Knoevenagel缩合，间氯过氧苯甲酸环氧化，碱性过氧化氢环氧化，DCC缩合酯化等反应合成了3个鬼臼毒素中间体。

The fire coal falls on the chain fire grates from coal: bucket and hen goes into the furnace tank for burning, and the flame passes through the upper back arch of the combustion chamber and back snloke chamber and then through the second fire pipe Io the

燃料煤自煤斗落在链条炉排面上，进入炉膛燃烧后，火焰经过后拱上部燃烧室和后棚管烟室后进入二回程烟管到前烟箱，再由前烟箱折回第三回程管束后，通过热管空气预热器、多管除尘器，然后由引风机抽引经过烟囱排出。

The super high DP cototn linters pulp using cleaning produce technology, with the raw material cotton linters. After dry cleaning,alcoline,hydrogen peroxide cooking, beating, bleaching and pulping process, the products would be in roll or sheet size.

超高聚合度特种棉浆是利用清洁生产技术，以棉短绒为原料，经过干式除杂、碱---过氧化氢清洁蒸煮工艺制浆，再经过打浆、漂白、通过抄粕机抄造成型的卷状或片状产品。

The crossover operation in the traditional GA operating is that choose two chromosome cross only at random also you can cross a bit, match and cross partly, cross order and cross cycle etc.

传统GA算法中的交叉操作，是随机选取两个染色体进行单点交叉(也可以多点交叉、部分匹配交叉、顺序交叉和周期交叉等等)，但是不管是采用何种交叉操作，新的子代染色体某一基因位上的值都是由两个父代染色体中相应基因位值经过一定交叉运算(直接交换或经算术运算等)所得到的，采用这种交叉算子操作使群体经过多次迭代后群体中的个体开始出现极大的相似性，因此照此下去就会出现早期收敛现象，使得算法的收敛速度非常慢甚至只能求到问题的局部最优解。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
