为了研究方便，隐马尔科夫模型假设连续段长分布的时间是服从几何分布，但这与真实的分布规律并不相符。

As for continuous random variable, the connection of distribution function between random variable and its function -- a new random variable can be obtained first according to the definition of distribution function, then the connection between distribution densities can be obtained by derivation; thus the distribution density is solved.

对于连续型随机变量ξ来说，可由分布函数的定义先求出随机变量ξ和它的函数η=f这个新的随机变量的分布函数之间的联系，然后通过求导，得到密度函数之间的联系，从而求得η的分布密度。

As to the risk model with random premium rate, we concerned with discrete random variable, continuous random variable and general random variable. We derive the formula of ruin probability, the extreme during the total duration of negative surplus and the joint distribution of the surplus immediately before ruin and the deficit at ruin.

对于保费率为随机变量的一类风险模型，本文就离散的随机变量、连续的随机变量、一般的随机变量三个方面进行讨论，运用概率方法和风险理论的方法推导出破产概率、末离前最大盈余分布、破产前瞬时盈余与破产赤字的联合分布等精算量分布的一般公式。

结果：正常回肠黏膜层ZO-1和Occludin的分布相似，主要位于上皮细胞的边缘，细胞膜顶端，沿绒毛下方均匀连续分布；MLCK主要分布在细胞浆内。

Results show that with the increase of the convergence angle,light field in biological tissues and the reflectance enhanced in the beginning,after reaching the peak value,its intensity decrease quickly and the position of its maximum deflects from central position.

结果表明：随着光源会聚角的增大，组织内光场分布和组织漫反射的分布趋于集中，当大于一特定角度之后，光场强度的分布区域迅速扩大，强度迅速下降，同时强度出现极大值的位置开始偏离中心位置。

Trichogramma showed high control efficacy on cotton bollworm eggs after three times of release both in the second and in the third generation bollworm periods. The parasitism on the second and third generation bollworm eggs were 66.0%-70.7% and 76.0%-81.2%, respectively, which were significantly higher than that in the control (second generation: 7.0%-12.3%, third generation: 5.2%-7.4%). And the injury rate of cotton buds and bolls in the second and third generation bollworm were 2.2% and 3.1%, respectively, which were significantly lower than that in the control (second generation:8.5%, third generation: 20.9%). In the second generation bollworm period, number of bollworm eggs or larvae in the Trichogramma released cotton field did not differ to that in the chemically controlled field. But in the third generation, there were significantly less bollworm eggs and larvae in the Trichogramma released cotton field. There were more predators in the Trichogramma released cotton field. These results indicated that cotton boll worm in the transgenic insect-resistant cotton field can he effectively controlled by mass-releasing of T.

结果发现：棉铃虫卵在棉株不同部位的分布差异较大，2代棉铃虫卵主要分布在叶正面、叶背面和茎尖，3代棉铃虫卵主要分布于蕾铃；在放蜂田，赤眼蜂对棉株不同部位棉铃虫卵的寄生率差异较大，2，3代棉铃虫时期对叶正面、叫背面、茎尖、蕾铃的棉铃虫卵寄生率均较高，对叶柄和茎杆处卵的寄生率较低；并以3代棉铃虫时期的寄生率较高；在2，3代棉铃虫时期分别连续释放3次赤眼蜂，对棉铃虫具有很强控制作用，2，3代棉铃虫卵的被寄生率分别为66.0%~70.7%和76.0%~81.2%，均显著高于化防田的自然寄生率（2代：7.0%~12.3%，3代：5.2%~7.4%）；蕾铃被害率分别为2.2%和3.1%，均显著低于化防田（2代：8.5%，3代：20.9%；2代棉铃虫时期，放蜂田和化防田的棉铃虫卵量和幼虫数量差异均不显著，但3代棉铃虫以后，放蜂田棉铃虫卵量和幼虫数量均显著低于化防田，且放蜂田的捕食性天敌数量显著高于化防田。

It can be obtained that the structure of liquid Fe〓Si〓 alloys changes to be more open with increasing Si concentration. The Gauss decomposition of radial distribution function exhibits a Gaussian peak at about r=0.370nm on RDF of pure liquid Si as well as Fe-Si alloys, which means there are Si-Si covalence both in pure liquid Si and Fe-Si alloys.

对纯Fe、纯Si和Fe-Si合金的径向分布函数的Gauss分解显示，在纯Si径向分布函数的r=0.370nm附近存在一Gauss峰，表明纯Si熔体中存在Si-Si共价键；而在Fe-Si合金径向分布函数的同一距离范围内也存在一Gauss峰，表明Fe-Si合金熔体中也存在Si-Si共价键。

According to the data of the analyses,revealed the population of Cryptomeria fortunei exhibited clump distribution pattern,single-dominant community type,sporadic type population structure and is able to natural regenerate...

柳杉种群呈典型的集群分布，并随个体的增大，由集群分布向随机分布发展的趋势，为间歇型的种群结构。通过对天目山柳杉的起源及其更新类型的探讨表明：天目山柳杉林属天然林与人工林共存状态，并可通过幼苗库进行天然更新，但具有机会性和波动性，需林窗和林内倒木等条件。图3表2参25

The technique of parameters normalization based on piecewise estimating the cumulative distribution function is performed in this paper. In this way the non-Gaussianity in the means of the cumulative distribution of Mel-cepstral parameters is decreased. Thus GMMs with fewer mixtures could model them precisely.

本文提出了一种基于分段估计概率分布函数的规整方法，在概率分布的意义上降低特征参数偏离高斯分布的程度，从而可以用较低混合度的高斯混合模型对其建模。

Synthesizing the pattern on the level of genet and clone population, Cycas fairylakea population tends to be contagious.

综合分析基株种群和无性系种群的分布格局，可以判断仙湖苏铁种群分布格局趋向于聚集分布。
