Based on the results and discussion of those experiments, a adoptable utilization method of the α-olefins were given

对于从焦化柴油分离得到的直链α烯烃的利用，特别是作为化工合成原料的利用，还没有人进行过比较深入的研究。

The content and the proportion of amylose and amylopectin are important indexes of sorghum.

直链淀粉和支链淀粉含量及其比例是高粱品质的重要指标。

The main ingredient is rice starch, which contains 17 percent amylose, amylopectin 83%.

的主要成分是大米淀粉，其中载有百分之十七直链淀粉，支链淀粉83％。

All the resistant starches were found to be of high molecular weight containing amylopectin and amylose.

所有的抗性淀粉图谱显示分子量很高说明都含有支链淀粉和直链淀粉。

It is not a single molecule, but a mixture of amylose (straight chains of glucose subunits) and amylopectin.

淀粉是葡萄糖的多聚体，不是一个单独的分子，而是直链淀粉和支链淀粉的混合物。

The analysis of the effect of N,P and K on amylose content ;2. Flour samples were taken from different sections of flour stream in a flour milling process,and the amylose content s in the flour samples were determined.

在同一生产线上对同一品种小麦按加工系统取制面粉样品，测定各粉样的直链淀粉含量；选择部分样品在其中添加整个粉路中最具代表性的系统面粉制成的谷朊粉，使各样品蛋白质含量相等、质量接近，在这种的前提下，研究直链淀粉含量对面条品质的影响。

The force is dominated by entropy force when the chain isdeformed less than 0.9 of the full-extended chain, while by enthalpy force. Theenthalpy force is contributed by the intro-molecular interaction. Bond stretchcontributes to the force more than bond angle bend. Torsion and VDW contributelittle to the force.3. The internal energy contribution to the elastic force It is in dispute that whether 〓 is dependent on the strain, and it is hard toresolve the problem using present elastic theories because they are athermal.

我们模拟了聚乙烯模型聚合物的SMFS，研究了链长、势能有效距离和温度对力谱的影响，探讨了力谱的本质问题，得到以下结果：改进的分子动力学方法可以很好的模拟聚合物的SMFS；SMFS是链段的性质而不是整个高分子链的性质，对于聚乙烯，该链段碳原子数目大于40；SMFS的本质是熵弹性，形变小于全伸直链的0.9时，力为熵弹力；形变超过全伸直链的0.9时，能弹力占主导地位，这种能弹力完全是分子内相互作用引起的，是由键伸缩和键角弯曲贡献的。3。

This paper aimed as the separation of α-olefins from kerosine distillate of delayed-coking process and their application.

本文研究了采用尿素脱蜡工艺从延迟焦化柴油中分离出C〓-C〓的直链α烯烃和直链烷烃的工艺路线，其中采用异丙醇和水混合溶剂溶解尿素，与焦化柴油进行络合反应，这在文献中尚未见报导。

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。
