The results indicated that along with the increase of chilling requirement of varieties, each differentiation stage for different varieties was delayed, the sepal differentiation stage was extended, the pistil differentiation stage was shorten. The time difference of petal and stamen differentiation stages was little among different varieties.

结果表明：随着品种需冷量的增加，不同品种花芽分化的各个阶段开始的时间有所推迟，萼片分化期所用的时间逐渐延长，雌蕊分化期所用的时间逐渐缩短，而花瓣和雄蕊分化期所用的时间差异不大。

These results indicated that ES cells with lower level of spontaneous differentiation could go into neural differentiation, while those with higher level of spontaneous differentiation would dedifferentiate and die during neural differentiation.

在进入神经分化的细胞中，其分化的进程与预培养24h组相似，但向外迁移的细胞减少，缺乏广泛的神经纤维联系。

Microcosmic syndrome differentiation has its superiority and limitation. There are some problems in developing microcosmic syndrome differentiation, such as lack of standard for syndrome differentiation, contradiction between single microcosmic index and the entirety, nonspecificity of the relationship between microcosmic indexes and syndromes, and the influence of disease on microcosmic syndrome differentiation, discrepancy between the essence study of TCM syndromes and the clinical practice.

微观辨证&有其优越性和局限性，&微观辨证&的发展尚存在一些问题，诸如：中医证候尚未规范化、微观指标单一性与整体性的矛盾、微观指标与证候对应的非特异性、疾病对&微观辨证&产生的影响、&证本质研究与临床治疗脱节等。

The results show that the period-adding bifurcation obeys the deterministic mechanism decribed by Chay model and lightly affected by stochastic factors. In the corresponding parameter region, the integer multiple spiking generates only when the stochastic factors are introduced to the model. The phenomenon is autonomous stochastic resonance.

从模拟实验结果的角度看，加周期分叉过程遵从Chay模型决定的确定性机制，随机因素对其有影响但影响较小；而在相应的参数区间，整数倍节律则是在随机因素驱动下产生，是随机共振现象，是由确定性机制和随机因素共同作用的结果。

Since any n x n doubly stochastic circulant matrix has a unique representation as a polynomial of degree n - 1 in the shift operator wn, the classification problem of primes in the doubly stochastic circulant matrices can be reduced to the solution of an equation over a doubly stochastic circulant matrix.

The maximum principle of the optimal control for the stochastic systems described by Zakaj stochastic partial sifferential equationis proved by approximately minimum point theorem of E. Ekeland. The convexity and compactness of the set of control values is not assumed, and it is not necessary for the maximum principle about differentiability in control variables included in drift term of the stoch astic system and the integrand in index functional, and costate process satisfies the stochastic partial ...

The main contributions are summarized as the following.Firstly, assuming demand is segmented by order lead time, a joint pricing and capacity allocation model is formulated considering scenario-based demand. Due to the stochastic discrete variable in the model, robust optimization is used to solve the model. Numerical examples prove our model and method reflect the stochastic characteristics of demand and provide more pratical pricing and capacity allocation policies than other methods of deterministic and stochastic expectation programming methods especially when the capacity is tight.

本文的创新之处概括为如下几个方面：首先，假设制造企业根据交货提前期对市场细分，建立了考虑需求情境的BTO模式下制造企业定价与能力分配的集成模型，利用稳健优化规划方法对此随机模型进行转化和求解，算例仿真表明随机优化规划方法较确定性规划和随机期望值规划方法更好地反映了随机离散需求的分布和波动特征，更加接近实际运作情况；产能越紧张，各类需求的价格差距越大，三种规划方法给出的最优策略差距越大。
