小麦品种无性系变异改良技术研究

针对晋阳345和晋麦73两个定型品种存在抗寒性较差的缺点,对其幼胚愈伤组织进行了4种处理:1、愈伤组织在MD培养基上继代2～3次;2、愈伤组织在紫外灯下约10cm照射2h;3、愈伤组织在低温2℃和常温25℃下交替培养30d;4、愈伤组织在紫外灯下照射2h后,再在低温2℃和常温25℃下交替培养30d。结果表明,4个处理后代R2主要农艺性状的变异率差异显著,且紫外灯照射幼胚愈伤组织的变异率比低温2℃和常温25℃交替处理幼胚愈伤组织高,其后代各种农艺性状的变异范围较大,变异率较高。但后者有利于改良抗寒性较差的定型小麦品种。     

Model of Survivable Architecture

Critical information system in Interact is in face of increasingly security problems. More attention has been focused on the survivability of information system, which is the capability of system to continue its mission even in the presence of damage to the system. The authors first introduce the definition of survivability. According to four function properties of survivability, which are Resistance, Recognition, Recovery, and Adaption, the authors design a model of survivable system structure and then explain survivability requirement, survivability strategy in this model. Additionally, they provide possible technical solutions for the survivability of systems, categorized by different aspects of our survivability strategy.     

Wavelet Edge Detection Method Based-on Multi-scale Fuzzy Logic

A novel edge detection algorithm is proposed by implementing fuzzy image enhancement at different scales.The implement of this algorithm can reduce the negative influence bring from the non-maximum suppression algorithm which select only one threshold.The success of the approach depends on the selection of a general fuzzy operator(GFO) for the enhancement of contrast of region after smoothing of image at different scales.Consequently,it is more obvious that coarse intensity changes are obtained at a large scale whereas the fine details of intensity changes are obtained at a small scale.A pretty performance is obtained by used this work.     

MACHINE PARAMETER IDENTIFICATION AND FAULT DETECTION FOR THE ALTERNATOR SYSTEM

In this paper, the machine( physical) parameters of the alternator system are on-line estimated on the basis of the derived system continuous-tims model, using Recursive Least-squares Estimation and Inverse Calculation Method proposed by Authors. Therefore, the estimated machine parameters can effectively track the changes of their true values and accomplish the fault detection for the alternator system. This paper gives a new way for machne parameter estimation and fault detection of the alternator systems.     

三个不同品质类型冬小麦品种籽粒淀粉积累动态及其有关酶的活性变化

在池栽条件下，研究了3个不同品质类型冬小麦品种藁麦8901（强筋）、豫麦49（中筋）和洛麦1号（弱筋）籽粒灌浆过程中淀粉及其组分积累动态和与之有关的酶活性变化。结果表明，3个品种籽粒灌浆过程中支链淀粉的合成均与直链淀粉的合成同时进行，灌浆中后期支链淀粉的合成比直链淀粉的合成快。豫麦49籽粒中直链、支链和总淀粉积累速率均高于其它两品种。3个品种籽粒中腺苷二磷酸葡萄糖焦磷酸化酶（AGPP）、尿苷二磷酸葡萄糖焦磷酸化酶（UGPP）、可溶性淀粉合成酶（SSS）、淀粉粒结合的淀粉合成酶（GBSS）、淀粉分支酶（SBE）活性变化均呈单峰曲线。豫麦49在灌浆期上述各酶活性变化的峰值均高于其他两品种，且大部分酶类在灌浆中后期仍维持较高活性。可见，与藁麦8901和洛麦1号相比，豫麦49具有较强的淀粉合成能力。     

Analysis on the Grain Growing Characters in Wheat under Different Seedling Density

通过对不同密度处理的小麦子粒生长过程的分析表明：小麦开花后子粒鲜重、体积均呈“低—高—低”的变化,鲜重的变化略滞后,开花后含水量则不断下降,下降速率最快时期与灌浆速率最高时基本吻合。用logistic方程拟合了不同密度小麦子粒灌浆过程,快增期的天数和灌浆速率比较稳定;缓增期天数和灌浆速率的变异系数较大。因此,在提高缓增期灌浆速率的基础上,延长灌浆缓增期是目前增加粒重的关键。
