Furthermore, the general formula is illustrated as the weighted summation of historical position states, so as to prove that in terms of cumulative iterations, parameters of PSO have an inherent forgetting characteristic in probability, moreover the searching mechanisms of canonical PSO and Barebones particle swarm are almost the same.

通过将粒子运动的一般性描述图解为历史状态加权和的形式，进一步证明了PSO参数随迭代周期的积累，在概率意义上的遗忘特性。分析表明在经过一定周期的搜索后，标准PSO方法同Barebones粒子群方法(Barebones particle swarm， BBPS)具有近似的搜索机制。

The third is known as the Fenian Cycle and is based during an era far more peaceful than that of the Ulaid Cycle, and the greatest hero of that era is Finn Mac Cumhaill.

And the self-shrinking generator is a typical model of the clock-conctolled During the past ten years or more, some researches have been done on the period and linear complexity of the self-shrinking sequence obtained from an m-sequence which is generated by a primitive polynomial f over GF(2), degree=n , in the related academies.

近十余年，国际上已对由n级m-序列导出的自收缩序列的周期和线性复杂度做了研究，给出周期的上下界，其中所给的下界为2~([n/2])，由此也给出了线性复杂度的下界为2~([n/2]-1)+1。

Education, with its cycles of instruction so carefully worked out, punctuated by text-books—those purchasable wells of wisdom—what would civilization be like without its benefits?

Chapter three studies the international trade transmission mechanism of business cycle, firstly it expounds the function of trade for the economy of one country, and secondly it analyzes the process of the transmission mechanism, which is also the theoretical basis of the next chapter.

第三章主要研究了国际贸易对经济周期的传导机制，首先论述了对外贸易对一国经济的作用，然后通过相关的模型分析了国际贸易是如何在国家间来传导经济周期的，这一章也是下一章的理论基础。

; 3 younger Dryas Only has reflection in the hundred-year-scales climatic curve, it is not evident in the curve of long period; 4 in the hundred-year-scales climatic curve, the last glacial maximum fluctuation as frequuently and 18-28KaBP was the stage in which the frequency fluctuation was the largest.

；（3）新仙女木事件仅反映在百年尺度的气候曲线上，在较长周期的饿曲线上不明显；（4）在百年尺度的气候曲线中，末次冰盛期气候波动频繁，其中18-28KaBP 是频率波动的最大阶段，但随着周期尺度的加大，气候的波动频率逐渐趋于均匀。

There has been a research indicating that geminin overexpression or cdt1 knockdown decreased the number of mitotically active cells and this effect depended on direct interaction between Geminin and Cdt1 .This balanced interaction of Geminin and Cdt1 is critical for the cell-cycle regulation.

在斑马鱼中研究发现，过量表达Geminin或者降低Gdt1的表达能减少有丝分裂的细胞数量，并且这种对细胞周期的效应直接取决于Geminin-Cdt1的相互作用，总之，Geminin和Cdt1的相互作用对细胞周期的调节非常重要。

The testing methods and targets were shown as below:Recorded milk weights from the 7th day postpartum to 15th day postpartum,and calculate the average day-milk yield;Milk samples were draw in 7th day and 14th day postpartum,and testing the milk fat,milk lactose,milk protein,milk Zn and the milk somatic cell counts;Blood samples were adopted at the 7th day postpartum,testing the levels of serum PRL; Blood samples adopted at the 1st day and the 12th day in oestrous cycle were used to test the levels of E_2 and P_4 in serum;In the experimental stage, registering the condition of parturition, the mean birth weight of calves,the first oestrus,the oestrus scycle postpartum and the conception rate of the first service after artificial insemination.

试验方法及所测指标如下：于产后第七天到第十四天记录日产奶量，最后计算每组平均日产奶量；每组随机抽取分娩后第七天、第十四天的奶样，测定乳糖、乳蛋白、乳脂、乳锌含量及乳体细胞数；于产后第七天，随机采取奶牛血样，测定血清中PRL含量；于发情周期的当天和第12天，随机采取血样，测定血清中雌二醇(Estradiol，E2)和孕酮(Progesterone，P)的浓度；记录奶牛的分娩情况、犊牛初生重、产后第一次发情日期、产后发情周期，并采用人工授精技术进行受精，记录第一情期受胎率，最后取平均值，作为衡量奶牛繁殖性能的指标。
