The results showed that the softening point of the asphalts rised linearly as the blowing time last, but the penetration decreased with the increase of softening point exponentially.

结果表明，在氧化过程中，氧化产物的软化点随着氧化时间的延长线性升高，针入度随着软化点的升高呈指数规律下降。

Subject this after studying and finding by diatom land reform, needle of pitch enter degree reduce, fall as low as most getting 70 (0.01cm), is it rise a bit to soften, height 50.06 ℃most, asphalt residue stability degree of mixture move steady degree improve to some extent, stating the high-temperature stability on the pitch road surface, water and stability, resist the serviceability , such as aging ability ,etc.

本课题经过研究发现经硅藻土改性后，沥青的针入度降低，最低达到70（0.01cm），软化点升高，最高为50.06℃，沥青混合料的残留稳定度及动稳定度有所提高，说明沥青路面的高温稳定性，水稳定性，抗老化能力等使用性能都得到改善；用水煮法对沥青混合料进行了粘附性进行测试表明，粘附性从3或4提高到4或5；硅改沥青的当量软化点，针入度指数等高温性能的研究发现，硅改沥青的高温性能有所改善；对粘弹指标的研究表明改性沥青的流动性变小；对抗水损害能力的研究表明，抗水损害能力有所提高。

The coal tar pitch powder was used with each of 22 kinds of dispersants prepared coal tar pitch water slurry,and 6 kinds of dispersants were selected to prepare coal tar pitch water slurry with the high temperature coal tar pitch powder which has a softening point of 105℃.

采用冷冻粉碎的方法将软化点为90℃的中温煤沥青制得粒度≤200目的煤沥青粉后，再与22种分散剂制备煤沥青水浆，从中筛选出6种成浆性好的分散剂再与软化点为105℃的高温煤沥青粉制备煤沥青水浆，结果表明中温煤沥青粉比高温煤沥青粉更易制得稳定性好的煤沥青水浆。

Softening point of the product is significantlyhigher than that of the product (64℃) without initiator.

其软化点明显高于未加引发剂的α-P与MA的反应物软化点(64℃)，表明前者的聚合度明显高于后者。

A spinable BN precursor is obtained with a softening point of 40~50℃, which can be changed to 60~70℃ by heat treatment.

合成的BN先驱体，软化点为40~50℃左右，且热处理后软化点的温度可提高至60~70℃左右，可纺性能良好。

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。
