The positive region based on radix sorting is used to get the positive region condition attributes set of decision attributes and the condition attribute set which excludes one of the condition attributes of decision attribute positive region. Then the difference between the two radices of positive regions is calculated to judge whether the condition attribute is a core attribute, thereby all the condition attributes are judged and the required core is quickly acquired.

There were no significant facilitating effects to the retention of signaled information in the overuse of text signals condition, but there were in the selective use of text signals condition. Experiment 3, in which 2 small experiments contained, studied the effects of reader-based factors. Experiment 3a examined the effects of the familarity to the text topics and the readers' reading levels. Experiment 3b explored the effects of cognitive style and the intention to use the text signals. The results were as the follows: There were no significant difference between the signaled and unsignaled conditions in the circumstance of high familarity to the text topics, but there were significant differences between them in the circumstances of lower familarity to the text topics. There were no significant differences between the signaled and unsignaled conditions for the field-independent participants, but there were for the field-dependent participants. All the participants with different reading levels were helped by the text signals.
实验3 对不同主体因素条件下文章标记效应进行了研究,分2个分实验,实验3a以高中二年级学生为被试,研究了文章主题熟悉程度与阅读水平对文章标记效应的影响,实验3b以初中二年级学生为被试,探索了读者不同的认知方式与标记利用的意向对文章标记效应的影响,实验3结果发现,读者的阅读水平、对文章主题的熟悉程度、认知方式和利用标记意向等因素影响着文章标记效应,在文章主题熟悉的条件下,有无文章标记无显著差异,但在主题不熟悉条件下,有文章标记的效果显著优于无标记的效果;对场独立被试而言,有无标记无显著差异,但对场依存被试来说,有标记条件显著优于无标记条件;文章标记对不同阅读水平被试都有显著促进效应;文章标记利用意向对场独立与场依存被试都有显著促进效应。

At present, diesel oil plays a more and more important role in the various kinds of fuel. But compare to gasoline, diesel oil has a high rate of sulfur compound. The sulfur compound is existed mainly as thiphene and thiphene ramification. These kinds of sulfur compounds are not easy to remove by adding hydrogenation. Thats why diesel oil has a high rate of sulfur compound. So it makes profound desulfurization a hot topic and a difficult problem in and outside the country. This paper takes dibenzonthiophene as a model to study the profound desulfurization of diesel oil with the help of biology and the oxygenating desulfurization under the condition of ultrasonic and microwave.
目前,柴油在燃料油中占的比重越来越大,而柴油较汽油馏分重,其硫化物主要以噻吩及噻吩衍生物的形式存在,这类硫化物用加氢的方法难以脱除,使柴油的含硫量较高,因此柴油的深度脱硫是国内外研究的热点和难点,本文以二苯并噻吩作为模型化合物,考察微生物的协同条件下对柴油的深度脱硫,超声波条件和微波条件下的氧化脱硫,并对超声波条件和微波条件下柴油的深度脱硫进行了对比。

Significant effects of warming onbiomass allocation were only found for the A. faxoniana seedlings grown under lowlight conditions, with significantly increased in leaf mass ratio and decreasedin R/S in responses to warming manipulation. The carbon allocation responses of B.albo-sinensis seedling to warming under full light conditions were similar with theresponse of A. faxoniana seedlings grown under low light conditions. Warmingsignificantly decreased root mass ratio, and increased leaf mass ratioand shoot/root biomass ratio for the B. albo-sinensis seedlings grown under fulllight conditions.
