二棱大麦白化颖壳和旗叶紫耳突变的遗传分析

 对大麦突变品系 2 98113的白化颖壳和旗叶紫耳 2个色变性状的遗传规律进行了研究。结果表明 ,白化颖壳性状和旗叶紫耳性状都属细胞核遗传 ,前者是由单基因控制的隐性性状 ,后者是由单基因控制的显性性状 ,而且两者是独立遗传的。此外 ,试验中还发现分离群体中所有白壳植株的叶鞘基部都为白色 ,绿壳植株的叶鞘基部均为淡绿色 ,未出现重组类型。由此推知 ,白色叶鞘基部性状可能是白化颖壳基因一因多效的表现 ,也可能这 2个性状是紧密连锁的。     

Analysis of the Sediment Development and Trend In Jinshajiang River Drainage Area

Jinshajiang River, which has a drainage area of 485,100 Km 2, average flux of 142.9 billion m 3, and soil conveyance of 247 million t/a, is the largest branch of Changjiang river. It is also the largest soil resource of the Three Gorges reservoir and upper reach of Changjiang River. To research the development and trend of Jinshajiang sediment not only has a relation to Jinshajiang water resource strategy, but also has important meaning to control the silt in Three Gorges reservoir and the Changjiang water resource development. The paper statistically analyses the flux and sediment conveyance of the Pingshan station, which is the primary hydrological station in the Jinshajiang River Drainage Area. Through several non-parameter statistical methods such as Spearman order correlativity check, Kendell order correlativity check, and linear regression check, the paper concludes that the sediment evolvement trend of Pingshan station is not distinct.     

在骨架镍上松香催化加氢反应的研究

测定在不同类型搅拌器下高压釜的持气量和反应效果，认识到骨架镍上松香催化加氢是外扩张控制的反应。采用溶剂法、双层组合式搅拌器及改变搅拌转速达到了消除外扩散影响的目的，从而使骨架镍显示出与贵钨Pb/C催化剂相似的活性。在反应过程中，在线跟踪了反应物和产物的浓度随时间的变化关系，结果表明在170℃、5．0MPa的反应条件下，枞酸加氢生成二氢枞酸和四氢枞酸是并行反应。     

Real-time Vehicle Scheduling

The traditional scheduling for vehicle is option in the fixed network. But it can't satisfy the real time environment. The demand of order is changeable and uncertain in real environment. It is convenient for scheduling transforming it into static data, but can't get the advantage on time. This paper proposes a real time vehicle scheduling on the study of traditional scheduling and discusses the model structure and the key technology for the real time system that establishes the base for develop teal time system.

Numerical simulation on multi jet diffusion combustion of low concentration coal bed methane

It is important to utilize coal bed methane to achieve the safe, environmental and economic benefits. The authors simulate the processes of multi jet diffusion combustion of low concentration coal bed methane using k ε turbulence model,non premixed combustion model and P1 radiation model. The influences of different geometrical structures and operating parameters on the combustion process are compared with each other. The results show that the distance between the gas nozzles and central axis,the angle of gas deflected from air ,the velocity ratio of air to gas have important impacts on the combustion. When the distance, the deflection angle and the velocity ratio are 30 mm,45 °and 2, respectively. The best combustion result can be achieved.     

Power supply and electromagnetic simulation of implantable medical devices

It is studied how to charge the battery of the implanted medical device through the skin according to its bio electrical characteristics.Energy delivery model of volume conduction is created by FEMlab 3.3 (Finite Element Model Lab),using AC voltage as the input.In simulation,the frequency characteristic of the model is tested,and then 4 different shapes of electrodes are designed.Taking cylindrical electrode for example,the shape and layout of electrode are optimized by changing the electrodes’ cross section areas and the distance between the electrodes.According to the simulation results,current transmitting efficiency can reach above 30% under the premise of ensuring human security.
