1 . the heredity of strain yz - ii6 is quite stable because there is no any change for hydantoniase activity , even after passing the generations for 8 times 结果表明，该菌株的遗传稳定性好，连续传八代后海因酶活性仍无明显变化。
Compared to the driver set of our main kernel - image - 2 . 4 . x - yz packages , some non - essential drivers have been removed in order to minimize the number of floppy disks needed 和我们主要的kernel - image - 2 . 4 . x - yz套件中的驱动程式集相比，我们移除了一些非必要的驱动程式，以尽量减少所需的磁片数量。
And strain ss - ori is sinorhizobium sp . according to the " blast " data . in addition , a hydantoinase gene ( 1440bp ) from yz - ii6 was amplified by pcr with genomic dna as the template 我们还利用pcr方法从菌株yz - 6基因组中克隆得到了海因酶的基因( 1440bp ) ，并构建了表达质粒pet3a - hdtase 。
Finally with an ensample of sale subsystem of yz - erp , the operating and realizing processes of the system are present . these analyzed and proved the feasibility and practicability of the mvc mode 最后以yz - erp销售子系统的一个功能模块(销售合同管理功能模块)为例，描述系统操作实现过程，分析并证明了设计模式的可行性和实用性。
Two dna fragments encoding d - hydantoinase gene were amplified by pcr from chromosome dna of pseudomonas putida yz - 26 and sinorhizobium morelense ss - ori , respectively , and confirmed by dna sequence analysis 序列分析表明，来自yz - 26菌的d -海因酶基因全长1440bp ，编码479氨基酸，基因序列已被genbank登录( ay387829 ) ，被确定为一个新基因。
The competition among the mobile telecom companies in china market is upgraded . such phenomenon is very typical in yz city . the more and more keen competition shows the coming of mobile telecom industries " mature period 移动通信产业的飞速发展使得手机消费逐步普及并趋于多样化，市场竞争不断升级， yz市的表现尤为突出，成熟期的产业特征已渐渐凸现。
5 . the morphology of the two strains also shows that the flagella of ss - ori are around the cells , whilst the strain yz - ii6 has only a single flagellum grown at the polar of cells besides the different of cell size , though they both are bacillus and gram - negative 形态和生理生化特征也表明， ss - ori菌周生鞭毛，革兰氏反应呈阴性， yz - 6菌为极生单根鞭毛，革兰氏反应呈阴性。
The purpose of this paper is to draw a clear outline of mobile telecom market of yz city and give the exact information of business competition and consumption through the analysis of the market research . the thesis is composed of six chapters 本篇论文旨在通过对yz市移动通信市场调查结果的分析，力求较准确地把握市场竞争态势和客户消费状况，为运营商勾勒出清晰的市场轮廓。
During cloning hydantoinase gene from the original strain ss - ori , we occasionally picked up a colony ( yz - ii6 ) which occurred a high hydantoinase activity . a series of experiments were performed to confirm whether this strain was the same as the original one 我们在克隆出发菌株ss - ori海因酶基因的过程中，偶然得到了一个能呈海因酶阳性反应的菌落，定名为yz - 6 ，并做了较为细致的研究。
Using the two - stream fluid model , the linear dispersion relation is derived assuming a two - dimensional spatial geometry . two cases are considered , one is that the 2d spatial geometry is defined by the plane containing the two counterstreaming electron populations and the perturbation wave vector ( referred as the xy plane ) , and the other is that the geometry is defined by the plane being vertical to the two counterstreaming electron populations ( referred as the yz plane ) 对高能束流和电子回流构成的双流系统，建立冷等离子体流体模型，采用简正模分析方法，分别考虑扰动波矢在平行于电流传播方向的平面(记为xy平面)上和在垂直于电流传播方向的平面(记为yz平面)上这两种情况，推导了不稳定性的色散关系。
