随机

Of the 32 branches and offices, a strong after-sales network nationwide, 24 hours engineers were waiting.

全国32个分公司及办事处，强有力的全国售后网络，24小时工程师的随机等候。

The samples actually observed. In contrast Bayesian methods view the parameters as random variables having some known a priori distribution.

与此不同的是，贝叶斯估计则把待估计的参数看成是符合某种先验概率分布的随机变量。

First, the concept emergence probability is assumed to be a random variable with a priori Beta distribution. Second, its priori parameters are designated by the distance-based similarity algorithm, calculated by Bayesian Estimation.

该算法首先假定概念出现概率是符合Beta分布的随机变量，然后基于语义距离的相似度算法计算先验参数，并根据统计样本计算该先验分布下基于最小风险的贝叶斯估计后验参数。

In this algorithm, the direction-of-arrival is assumed to be a discrete random variable with a priori probability density function defined on a set of candidate points. Whether or not the secondary sample is required is based on the a posteriori probability distribution of a set of candidate point"s, which can be calculated from the array received signals. And then, the resulting beamformer is a weighted sum of the beamformers pointed at the latest set of point"s, which are combined according to the value of the a posteriori probability for each pointing direction.

在该算法中，期望信号的波达方向被看作是一个定义在若干候选波达方向上的离散随机变量，由阵列接收信号计算出各候选波达方向的后验概率，并将后验概率的分布作为是否需要进行二次采样的判断标准；随后，对各波达方向上的波束成形权值线性加权，便可得到自适应波束成形器，权系数为各候选波达方向的后验概率值。

Considering the effect of rough sea, a program called GRWAVE1 which may compute the electric field strength and phase has been written.

在地波程序GRWAVE的基础上，考虑了随机粗糙海面的影响编制了程序GRWAVE1，该程序既可计算地波场幅度又可计算其相位。

Methods: for abdominal CT scan of 240 elderly patients were randomly divided into two groups.

选择进行腹部CT增强扫描的老年患者240人，随机分为两组。

MATERIALS: Twenty healthy male SD rats, out of which 15 ones were used to prepare the models of gastric mucosa injury through administration of absolute alcohol by gavage, and the other 5 were used as controls.

材料：健康雄性SD大鼠20只，随机选15只用无水乙醇灌胃法制备胃黏膜损伤大鼠模型，剩余5只为空白对照。

Chapter 5, an example is given by stochastic simulation method, which is the application of least absolute deviation estimate in location by GPS.

第五章通过随机模拟的方法，给出M估计的特殊情形——最小绝对偏差估计在GPS定位中的应用。

The least absolute deviation of the random censored data nonlinear regression model ［J］.

随机删失数据非线性回归模型的最小一乘估计［J］。

Results In the specific amplification of RHD genes with the PCR-SSP, the negative results were found in 50 random Rh-negative sampleswhile the positive results were found in 51 random Rh-positive samples.

结果用PCR.SSP方法特异扩增RHD基因，50份随机Rh阴性样本呈阴性结果，51例随机Rh阳性样本呈阳性结果。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
