The primers and the detection programs have been used to detect the pathogens in the inoculated-diseased cucumber plants .The details are reported as follows: 1. By using the primers ITS1/ITS4, only Fusarium isolates could be amplified to produce a special fragment of 750bp. This product generated 480bp, 200bp and 100bp fragments after digested by restriction enzyme HinfⅠonly from the pathogen of Cucurbits Fusarium Wilt.

引物ITS1/ITS4只在镰孢属菌株上扩增到一条750bp分子片段，其他供试菌株无扩增条带产生，扩增产物经HinfⅠ酶解后，只有瓜类尖镰孢菌产生480bp、200bp和100bp 3条带，说明该PCR-RFLP程序对瓜类尖镰孢菌具有特异性；巢式PCR引物BIK1/BIK4和BIK2/BIK3只有在黄瓜尖镰孢菌菌株上扩增到一条800bp分子片段，其他菌株均无扩增条带产生，说明该巢式PCR程序对黄瓜尖镰孢菌具有特异性。

Through comparing exon sequences at both ends of introns of CHD genes of jungle fowls and cygnets, exons on two ends thereof are respectively designed with an upstream primer and a downstream primer: Psf: 5'CAAGGATGAGAAACTGTGCAA3'; and Psr: 5'GAATATCTTCTGCTCCTACTG3'; and the Psf/Psr primers are used for amplifying the CHD genes on Z and W chromosomes of meat pigeon feather pulp genome DNA, and finally the sex is identified according to the band type through 10 percent polyacrylamide gel electrophoresis and silver staining, wherein, female shows two bands and male shows one band.

通过原鸡和小天鹅CHD基因内含子两端的外显子序列比对，在两端外显子上分别设计上下游引物：Psf：5'CAAGGATGAGAAACTGTGCAA3'；Psr：5'GAATATCTTCTGCTCCTACTG3'；再以Psf/Psr引物扩增肉鸽羽髓基因组DNA的Z和W染色体上的CHD基因，最后经过10％聚丙烯酰胺凝胶电泳、银染，根据带型判断性别，其中雌性为两条带，雄性为一条带。

Nevertheless, the pollution extents of these two dements are rather apparent at a distance beyond 500 m from the roadbed.

在距路基10m范围内为土壤重金属重度污染带，10～100m范围内为中度污染带，100～500m范围内为轻度污染带。

Genetic variation in demes appeared 8 times higher than among demes. The paper also gave a few methods such as dendrogram, statistic, frequency of markers, polymorphic bands and special loci, genetic variations within and among demes for conservation and utility, molecular checking indexes for cultivars can provide basic information for protection of intellectual property rights and selection of wanted cultivars.

通过多态带和特殊带提出了桃核心种质，并利用聚类法、统计法、标记频率法、多态带数和特殊位点法、类群间和类群内的遗传差异法提出了种质保存策略；以及品种识别分子检索表的建立，为知识产权保护和正确选择品种提供了第一手资料。

Both transmission and reflection dispersion, with regard to parameters and frequency detuning, are quantitatively studied.

研究表明：光纤布拉格光栅的透射色散和反射色散在禁带边缘有很大的色散；在禁带内布拉格波长两侧，以及禁带外两侧，光纤布拉格光栅具有相反的色散特性。

Contrarily, cationic surfactant CTAB and nonionic surfactant_9 have the same effects: the two substances\' enterings cause the superficial enzymatic activity to decrease rather than the total loss in whatever the buffers. There is no Soret movements except that a longer wavelength movement by_9\'s treatment under pH5.2 buffer condition.

阳离子表活剂CTAB和非离子型表活剂9的作用结果类似：无论SBP带何种净电荷，两类物质的加入使得表观酶活力降低但不是完全失去：紫外-可见电子吸收光谱上特征Soret带位移保持不变；只是9在pH5.2缓冲液中Soret带发生红移。

Instruction: friction band is installed between vacuum box and adhesive belt with airproofing, lubrication and cooling to lessen resi

真空皮带脱水机备件摩擦带摩擦带 friction band 说明：摩擦带是安装在真空盒与胶带之间，并以水密封、润滑、冷却，减少胶带运行的阻力。

The typical spot symptoms on fruit would decrease the production and merchandise of tomato in the heavy rain of June and July; therefore, the key period for disease control is after rainy season. Quick identification on pathogen was using PCR. 1476bp band was amplified by primer P3、P4of bacterial speck. By using primer CMM5、CMM6 for bacterial canker, 614bp fragment was amplified. These PCR tests provided important foundation for pathogen identification and disease diagnoses. Using primer RST65 and RST69 for bacterial spot, expected 420bp band was not amplified.

通过聚合酶链式反应对病原进行快速鉴定，证明加工番茄细菌性斑点病用引物P3、P4可以得到一条大小为1476bp的特异性条带，番茄细菌性溃疡用CMM5、CMM6可以扩增出一条大小为614bp的特异性条带，这为病害的快速诊断打下了基础，但利用引物RST65和RST69对番茄细菌性疮痂病进行鉴定，没有得到预期420bp的目标条带，故对细菌性疮痂病的快速检测还有待继续研究。

In order to study the change of the thickness of gas hydrate stable zone and its effect on environment, 35 spots from four key areas in the southern South China Sea were selected to calculate it based on relative equation and program.

为了研究南海南部天然气水合物稳定带厚度在这个过程中的变化情况及其对环境的影响，我们利用相关的计算公式，并编制了计算稳定带厚度的程序，在南海南部的南沙海槽、曾母盆地、巴拉望盆地和苏禄海等四个重点海域选取了35个点进行末次盛冰期及目前稳定带厚度的计算。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
