The chain between air valve operational rule and bed stratification is set up, which supplies the reliability for control decision-making of expert system. Expert control strategy is put forward based on the characteristic of jigging process in this article. Knowledge acquisition, knowledge expression, search method and reasoning mechanism are studied in the expert system. The rule-base is set up based on bed stratification status, bed mobility status, feed velocity, recording data on site, artificial float and sink test result.

小技改出效益去年湖北随阳农场第一砖瓦厂用八目元将煤渣粉碎机由网筛状改造成了开口状，减少红砖度品损失一万多元；用一千元，改换了砖机加速器的主轴。

Conclusion］In order to make an accurate diagnosis, protect infants from dysphasia, it is necessary for infants failing in the hearing screening to have tests of click-ABR, ASSR, tympanometry and be followed up until 1~2 years old.

结论］对未通过听力筛查新生儿需进行click-ABR和ASSR及鼓室声导抗检测及动态随诊观察，从而给出准确的诊断。

These esophageal cell samplers performed equivalently, but the accuracy was still too low for a primary screening test.

我们的研究结果表明我们还需要进一步提高细胞学筛查的标准或者发展新的分子技术来更好的检查出食管的鳞状上皮病变。

It is greatly efficient, because this overcomes the shortcoming of Eratosthenes algorism that need compare every natural number in the given range, This algorism can acquire all prime numbers between 1 and any given natural number m This article also has given the complexity of the algorism, and even if sift in the algorism were different, it will be...

这避免了传统Eratosthenes 筛法需要比较每个数的缺点，极大地提高了算法效率。该算法能用于求1至任意自然数m之间的所有素数。同时还给出了该算法的最多比较次数公式，即使用不同的筛子利用该公式也容易求得其最大比较次数。

Fourteen wampee cultivars collected from Guangdong and Guangxi were used for RAPD analysis in this study. 16 primers selected from 150 random primers were used to amplify 87 DNA fragments and 57 bands (54.0%) showed polymorphisms.

摘 要：对14个黄皮品种进行 RAPD 分析，从150个随机引物中筛选出16个能在种质间表现出多态性的引物，共扩增出 87 条谱带，其中多态性带47条，多态性比例为54.0%。

The average percentage of polymorphic bands are 72.06% for ISSR and 66.67% for RAPD respectively. The genetic diversity of ginkgo revealed by ISSR (the average effective number of alleles is 1.8780, the average Nei"s gene diversity is 0.4652, and the average Shannon"s information index is 0.6574) are all higher than those by RAPD (the average effective number of alleles is 1.7842, the average Nei"s gene diversity is 0.4317, and the average Shannon"s information index is 0.6211), while the standard errors of the parameters estimated by ISSR were lower. Therefore, ISSR molecular markers are more suited than RAPD molecular markers when testing the genetic diversity of ginkgo populations and determining the genetic relationship of among populations or among individuals which are much similar hereditarily.

本文应用RAPD和ISSR两种分子标记技术，选取中国5个可能的野生银杏居群共计75个样品，对其遗传多样性进行了研究，得出以下结论：(1)用筛选出的12个RAPD引物和10个ISSR引物进行PCR扩增，分别扩增出65条和68条重复性高、清晰的条带，多态性位点百分率分别66.67%和72.06%，ISSR揭示的银杏遗传多样性(平均有效等位基因数目为1.8780，平均基因多样度为0.4652，平均信息指数为0.6574)高于RAPD所得到的结果(平均有效等位基因数目为1.7842，平均基因多样度为0.4317，平均信息指数为0.6211)，其所估算参数的标准差要低于RAPD所估算出的值，因此，在研究亲缘关系非常近的银杏物种的遗传多样性并试图确定居群间或个体间的遗传关系时，ISSR分子标记技术比RAPD分子标记技术更为合适。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.
