The SDS-PAGE electrophoresis indicated that all engineered strains containing different expression plasmid could apparently express a 45 kD band specific for daunorubicin C-14 hydroxylase. The expression level of doxA gene was much higher when the doxA gene was under the control of promoter PermE. However, it was found that fd terminator had few effect on the expression of doxA gene.

SDS-PAGE蛋白电泳实验证明，上述五个菌株都能够表达大小约45 kD的柔红霉素C-14羟化酶蛋白，并发现以在PermE启动子控制下的doxA基因表达量相对较高，而终止子对＠中英文摘要 dd基因表达似乎没有影响。

The process includes making samples using Superpave Gyratory Compactor, selecting gradation by the criterion of stone-on-stone contact and certain air voids in the mix and determining the optimal asphalt content limited by draindown test and expected air voids as the main controllability condition. It is suitable to increase the asphalt content of the mix in the range of expected air voids, which can ensure the compatibility of function and durability of porous asphalt.

该方法采用旋转压实仪成型试件，通过计算法确定初试沥青用量，以石-石接触和一定条件下的空隙率作为设计级配选取的根本依据，在最佳沥青用量的确定中，以沥青析漏损失和空隙率作为主要的控制指标，在设计空隙率的基础上，通过使用纤维增大沥青用量，以保证沥青混合料兼备功能性和耐久性。

Namely, this system utilizes perfect GPS combines GIS of transportation and tele鎜m industry broadened mobile communication network of GSM in china, with the help of data operation of GIS and spatial analysis technology, this build up a conducting control system which put together transference conduct scientific management, harmonial operation and safety defence, it also strengthen the safety defence ability of some unforseseen hazard and so on.

For such complex and composite systems as analogue and digital systems, electronic and mechanical systems, the Ptolemy II attain purposes with heterogeneously hierarchical ideology, in other words, actors and model of computation at the same level stand for a behavior of the system, and these components at this level can be converted into a composite actor that stands for another behavior of the system under the control of different models of computation at upper level with other actors. In this way, the system may be structured hierarchically.

对于复杂的混合系统，如模拟与数字系统，电子与机械系统，Ptolemy II采用层次异构的思想实现，即同层的角色和计算模型表示系统的一种行为，而这一层组件又可转变为一个复合角色，在上一层与其它角色在不同的计算模型控制下表示系统的另一种行为，从而实现系统的层次构架。

The thesis also discussed the synthetic influence of above factors on dynamic diagenesis in detail and graded dynamic diagenesis into three types, which were respectively thermally dynamic diagenesis, tectonically dynamic diagenesis and hydrokinetic diagenesis, and then the types of diagenesis controlled by dynamic factors had been studied: 1 thermally dynamic diagenesis, clarified the ration relationship by the conception of the thermally evolving track and the thermally maturity, 2 tectonically dynamic diagenesis, changed the porosity of reservoir mainly by tectonically movement;3 . hydrokinetic diagenesis, changed the physical and chemical properties resist-press intensity of the rock by the participating of liquid.

在研究以上控制因素的基础上，将成岩动力作用分为热动力、构造动力、流体动力成岩作用三种类型：1、热动力成岩作用，运用热演化轨迹和热成熟度的概念研究与成岩作用之间的定量关系，砂岩孔隙度随热成熟度增加而呈指数减小；2、构造动力成岩作用，盆地构造变形可以使砂岩的孔隙体积在相对短的时间内产生明显的变化，构造滑脱推覆作用比水平侧向挤压作用压实减孔量小，可保留更多的孔隙度；3、流体动力成岩作用，化学成岩反应是在流体参与下完成的，它改变了岩石的物理化学性质，改变了岩石的抗压强度。

The modified ilioinguinal approach does not allow isual control of this osteotomy, and the descriptions by Ganz et al.5,9,10 must be strictly followed.

改良的髂腹股沟入路不能行目视下的截骨术，而且必须遵循Ganz等人描述的方法，在透视控制下行截骨术或许对医生有帮助。

With the emergence of the global economic crisis, the status of agriculture is getting more and more important ineconomic development. In this environment, the require of the precision control of the environment factors that crops need if getting more and more high, so the key is the collection and transmission of various types of the basic data. The new technology of Wimesh is the solution of this problem.

摘 要：全球经济危机的出现，使得农业在一个国家的经济发展中的地位日益凸显，在这样的环境下，农业生产领域中对农作物所需求的环境因素的精细控制要求愈来愈高，因而涉及各类基础数据的收集及传输就是其中的的关键，而新兴的Wimesh技术所具备的特色使得其在这样的精细农业生产中大有用武之地。
