Binomial distribution is preferred in testability demonstration,but it is discrete.Because of calculation difficulty,the sampling plan is usually worked out with some adaptations.

在测试性验证中首选的二项分布是离散取值的，由于计算困难，确定抽样方案通常采用一些变通的方法。

Using binomial distribution P + Q = 1 to describe "succession attribute" of three suffered stand systems, the coefficients of 1, 3, 3, 1 in the binomial equation of3 will become assessment of probability in different attributes of systems.

对3个蠢害林分系统的"演变属性"用二项分布P+Q=1来描述，那么二项式3方程中的系数1、3、3、1成为系统中不同"演变属性"的概率论判断。

The probabilistic detection of subliminal channels mainly under Bernoulli test with binomial distribution is studied. Some results of the security of many-time-used channels in hypothesis test model based on relative entropy are obtained. 6. The schemes to avoid the subliminal channels are summarized and compared with each other.

According to the study of former researcher, the paper puts forward basic hypothesis of building cluster brands, and constructs the model of transformation for the mode of cluster brand. The paper takes Datang socks cluster for example, and tests the model with t-test and binomial distribution test.

本文根据国内外学者的相关研究，提出建设集群品牌的基本假说，据此构建了集群品牌发展模式转换模型，并以浙江大唐袜业集群的品牌发展为实证，运用t检验和二项分布检验对该模型及假说进行了检验。

We also studied the capacity of Newton channel. 5. The security conditions of one-time-used channels are given. The probabilistic detection of subliminal channels mainly under Bernoulli test with binomial distribution is studied. Some results of the security of many-time-used channels in hypothesis test model based on relative entropy are obtained.

To analyse the signal test, binomial probability law was used for significance testing of signals in the images emitted from human hand in different period of time, which proved that human hand can emit ultra-weak bioluminscence, the photon inensity emitted from fingers is in the range of 300～550 photons/s and the whole hand in 850～1200 photons/s.

为分析图像中的信号检验，二项分布被用于人手不同时间累积发光图像中的信号显著性检验，证实人手存在超微弱生物发光，手指的发光强度在300～550photons／s范围内，全手的发光强度在850～1200photons／s范围内。

Thus, the probability of accepting a lot may be computed using binomial tables.

这样，接受该批的概率可用二项分布数值表计算。

Next, it has a form of compound Poisson distribution when claim amount is Logrithmic.

负二项分布之所以在风险管理中被广泛应用是由其优良特性所决定的。

Firstly, we discuss several two-sided confidence intervals of binominal distribution such as: the Standard interval, the Wilson interval, the Agresti-Coull interval, Jeffreys interval, and do some comparative analysis among them, mainly consider the average converage probability and the average expected length of the co...

我们先介绍了二项分布参数的几种双侧置信区间：标准区间、Wilso区间、Agresti-Coull区间和Jeffreys区间，并对它们进行了比较分析，主要从置信区间的平均覆盖率和置信区间的期望长度来考虑。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
