查询词典 sample case

Some troubles emerge when we use regression estimator in such a case:in a continuous survey research,when the prior sample and the present sample are independent and they have different elements,we can not compute the regression coefficient.

作连续调查研究抽样时经常用到回归估计。如果前后两个样本相互独立，并且它们所包含的元素不同，就无法直接计算出回归系数。

For the case where the sample covariance matrix is unknown or the sample support is not sufficient to form the sample covariance matrix, we carry out the spatially smoothed CSA-MSWF to quickly find the signal subspace and the noise subspace.

如果阵列协方差矩阵是未知的，我们采用空间平滑的CSA-MSWF快速计算信号子空间和噪声子空间的基矢量。

Fisher criterion assumes that each sample has a unimodal,symmetric distribution for each class.However,when the training sample size is large and their distributions are multimodal or skewed,the definition of classical Fisher criterion can not correctly reflect the distribution of the data in the sample space,in that case,the sets of discriminant vectors are not optimal virtually.

Fisher准则函数的前提条件就是假设每类样本数据满足单峰高斯分布，即各类样本在模式空间的分布近似椭球状，但是当训练样本数据较多且呈多峰分布时，传统的Fisher准则函数并不能准确反映样本数据的分布，显然基于Fisher准则函数的线性判别分析得到的最优判别矢量集也不是最优的。

In the first case, the products of the MFW4/31 amplification were loaded when bromophenol blue dye from MFW7/9 sample migrated to a 3-cm distance from the wells, while in the second case, MFW17/26 products were loaded when the dye from MFW13/20 reached 4.5 cm.

在第一种情况下，当溴酚蓝染料从MFW7/9 样品迁移到离加样穴 3-cm 距离时加入MFW4/31 扩增产物，而在第二种情况下，当溴酚蓝染料从MFW13/20 样品迁移到离加样穴4.5 cm距离时加入MFW17/26 产物。

B: Choose a pair of sample containers with bottle lids wrapped in plastics and see the numbers on the sample bottles and lids and pour 50ml of urine from the cup into bottle A, the rest 25ml into bottle B for retest in case bottle A is in doubt.

挑选一套样品容器，看清楚两个样品瓶子和瓶子盖上的号码。从杯中倒50毫升尿样到A瓶中。如果A瓶有问题的话，余下的25毫升倒入B瓶中，供重复实验。

Even Twinings company head the position of tea of count of the thunder that make case, also get the challenge of company of its competitor Jacksons Of Piccadilly, this company appeals to say, they just are the original producer of count tea, 2 worlds were in case thunder count to gave this company predecessor the company the recipe 1830, and the sample that when basis head comparatives, Twinings just offers undertakes is modelled on.

甚至Twinings公司首制格雷伯爵茶的地位，也受到其竞争对手Jacksons of Piccadilly公司的挑战，该公司诉称，他们才是伯爵茶的原始制作者，格雷伯爵二世在1830年将配方给了该公司前身公司，而Twinings只是根据首相当时给予的样品进行仿制。

Case of sample with 10cm length, weighing about 1/2 of two adjacent fabrics, put it between two adjacent fabrics (single-fibre cloth)each measuring 10 cm × 2cm, so as to make the sample thin layer, and sew roughly its four sides with white cotton sewing thread.

案件样品10厘米长，重约1 / 2的两个相邻的布料，把它与两个相邻的织物每个测量10厘米× 2厘米，从而使样本的薄层，并缝合大约4个双方以白色棉缝纫线。

Case of sample with 10cm length, weighing about 1/2 of two adjacent fabrics, put it between two adjacent fabrics (single-fibre cloth)each measuring 10 cm × 2cm, so as to make the sample thin layer, and sew roughly its four sides with white cotton sewing thread.

当样本为10厘米长情形时，称重约两个毗连织布1 / 2的重量，把它放在两个大小为10厘米× 2厘米毗连织布中间，以确保样本层的细薄，然后用白棉缝纫线粗略地缝制四周。

If this is the case, a sample from the child and the putative father are essential, with a sample from the mother being desirable but not essential.

如果是这种情况，样品从儿童和推定的父亲是必不可少的，从一个样品的母亲正在可取的，但并非必不可少的。

In most situations, the case sample used for tag SNP selection is more power than the control sample.
