对RP1的49个子代个体，R01的123个子代个体，进行ISSR遗传多样性分析及主成份分析，子代个体间存在一定的遗传差异，其中仍然以表现粉色及桔黄/桔红色的个体遗传多样性最丰富。

Percent and 21. 4 percent respectively. F1 plants of R01 self-cross also present diverse colors such as white, pink, red, nacarat/saffron, dark yellow, yellow and so on, And the pink and the nacarat/saffron plants have the highest proportions, 50.6 percent and 31. 4 percent, respectively. The wide segregation chromatogram of self-cross progeny implies that these two varieties themselves contain the abundant genetic polymorphism. The ISSR genetic diversity analysis and the principle factor analysis were performed using 49 plants of RP1 self-cross progeny population and 123 plants of R01 self-cross progeny population.

RP1及R01的遗传多样性最高，这从自交一代的表观性状及ISSR的遗传变异可以得到证实，如RP1自交，F1代花色有白色、粉色、玫瑰红、深红色、桔红/桔黄、黄色，黄红复色等，其中以粉色及桔红/桔黄色占的比例最大（分别占61.2％，21.4％）；R01自交，Fl代花色有白色、粉色、红色、桔红//桔黄、深黄色，黄色，其中以粉色及桔红/桔黄色占的比例最大（分别占50.6％，31.4％），较广的自交分离色谱，表明两个品系自身存在丰富的遗传多态性。

A new heuristic solution algorithm is presented using an improved genetic algorithm. In the improved genetic algorithm, nondifferentiable exact penalty functions are used to transform a constrained optimization problem into a single unconstrained optimization problem, and hybrid crossovers and intermittent are applied to increase the search capability.

设计了基于改进遗传算法的启发式求解算法，该算法借助不可微精确罚函数将约束问题转化为单个无约束问题来解决，采用混合杂交和间歇变异提高算法的搜索能力。

The characteristics of genetic algorithm,global searching of Genetic Algorithm for complex,multi-apices,and nondifferentiable nonlinear function are applied to the Hopfield neural network,which results in the inputting pattern getting away from the attraction domain of fault pattern and the Hopfield neural network associative memory remaining high success rate while the noise to signal ratio is high.

0引言Hopfield神经网络模型在神经计算、优化求极值、联想记忆等方而取得了重大应用，联想记忆能够从不完整的或模糊的信息中联想出存储在记忆中的某个完整清晰的图像模式，但一般离散Hopfield模型存在很多伪稳定点[2]，这些伪稳定点的存在，不仅使真稳定点的吸引域变小，而且使网络

INTERPRETATION: Similar to molecular genetic studies, we showed evidence that schizophrenia and bipolar disorder partly share a common genetic cause. These results challenge the current nosological dichotomy between schizophrenia and bipolar disorder, and are consistent with a reappraisal of these disorders as distinct diagnostic entities.

解释：类似于分子遗传学的研究证实了精神分裂症和双相情感障碍具有部分共同的疾病基因，对当前疾病分类学上这两类疾病的独立分类提出了挑战，有必要对它们显著的和特征性的本质再次进行认识。

By means of the novelly decoded manner and the well constructed fitting function, the global searching performance for the GA is developed so that optimized RBPNN approaches to the parsimonious structure;(4) A ROLS micro-genetic algorithm was built by integrating the micro-genetic algorithm with good convergence performance based on tiny class of group with the ROLS-SOA.

提出一种新的基于径向基概率神经网络的模式识别融合系统，即多分类器系统，避免了单一径向基概率神经网络分类器的分类局限性，减少了寻求单一分类单元结构最优化时的计算复杂度，通过使用D-S融合算法，大大提高了对复杂模式识别问题的分类精度。
