It was showed under the laser scanning confocal microscopy that : for dna level fish , 81 % of the dnas were in the nucleoli and at the periphery of the nucleoli and 19 % in the nucleoplasm ; for rna level fish , 22 % of the rnas were in the nucleoli , 78 % in the nucleoplasm and at the boundary between it and the nucleoli ; for dna - rna level fish , 25 % , 46 % and 29 % of the dnas or rnas were in the nucleoli , at the periphery of the nucleoli and in the nucleoplasm , respectively 结果如下： dna水平荧光原位杂交结果显示， 81的dna位于核仁内部及其核仁周边区域， 19的位于核质中； rna水平荧光原位杂交结果表明， 22的rna位于核仁内， 78的位于核质及与核仁交界处； dna - rna水平荧光原位杂交结果是， 25的dna或rna位于核仁内， 46处于核仁周边， 29位于核质中。由此推测出， rna聚合酶的转录主要发生在核仁及其周边区域。
Secondly , it can detect opened ports on the basis of results of the first port - scan , and get the information of service and version of these opened ports . thirdly , through many kinds of detecting ways , it can get the os - fingerprints of tcp / ip protocol stack of the destination computer , and guess the faraway operation system exactly . at last , taking cve ( common vulnerabilities and exposures ) as the standard , a more practical vulnerability database by combining the structures of two large - scale oversea vulnerability databases is designed 设计开发的网络漏洞探测系统具有较强的综合性能,能够提供多种端口扫描技术,在第一次扫描结果的基础上对开放的端口进行第二次探测,得到开放的端口的服务和版本信息,通过多种探测方法获得目标主机的tcp / ip协议栈指纹信息、较准确的推测出远程操作系统,并以cve ( commonvulnerabilitiesandexposures )为标准,结合国外两个大型漏洞数据库的结构,设计了较实用的漏洞数据库。
The force which had been stationed near tushins cannons to protect them had by somebodys orders retreated in the middle of the battle . but the battery still kept up its fire , and was not taken by the french simply because the enemy could not conceive of the reckless daring of firing from four cannons that were quite unprotected 在这次战役之中，不知是听从谁的命令，驻扎在图申主管的大炮附近的掩护部队离开了，但是炮台还继续开炮，它之所以未被法军占领，仅只因为敌军不能推测出这四门无人护卫的大炮具有勇猛射击的威力。
Ghrelin regulates pituitary growth hormone ( gh ) secretion . in the study , we obtained the cdna sequences of preproghrelin and the cdna encoding the ghrelin of duck , goose and emu by using rt - pcr and 3 " - race methods . and then deduced the amino acid sequences of preproghrelin and ghrelin in duck . goose and emu . sense and antisense primers were designed on the basis of chicken ghrelin cdna sequence ( dest accession no . ab075215 , 836bp ) and proventriculus cdna was performed as the template Ab075215 ， 836bp )设计引物，以鸭、鹅、鸸鹋腺胃cdna为模板，通过rt - pcr及3 - race的方法，将各个产物经过回收，再经连接转化，克隆测序，拼接后得到鸭、鹅、鸸鹋preproghrelin基因的cdna序列及ghrelin的cdna序列，并由此推测出preproghrelin及ghrelin的氨基酸序列。
