结果使用五等分分层法对临床试验中的非随机化数据进行处理，分层前两组协变量间的不均衡在分层以后达到了均衡。

In this paper,the algorithm of a kind of hierarchical competitive covering networks for the classification problems is proposed based on the introduction of quotient space theory,which defines granularity according to Huffman coding and Huffman coding algorithm.

文中在此基础上，利用商空间的粒度原理和霍夫曼编码的思想，对样本分布极其不均匀的分类问题，构造分层竞争覆盖网络。

The researchers concluded that the study accomplished the goal of devising a predictive model that , in the near future , may help stratify such patients based on prediction of the histologic severity of the disease .

研究人员得出结论，研究达到了在不远的将来设计出预测模型的目标，能够根据疾病的组织学严重程度预测来对此类患者进行分层。

SLD series bin container Lifter is mainly used in pharmaceutical industry for transferring and charging powder and granules. It can be used along with various main equipments, such as container blender, Tabler press, capsule filling machine and so on. It optimizes production-flow, avoid the dust and cross-contamination. It's the ideal transfer equipment in pharmaceutical industry for solid dosage section. Meanwhile, it can be also widely used in chemical industry, food-stuff industry, etc.

SLD 系列料斗提升上料机主要用于制药企业的粉状、颗粒状等固体物料的输送加料，可与混合机、制粒机、压片机、包衣机、胶囊填充机及包装机等工艺设备配套，能有效地减少交叉污染与粉尘，减轻了劳动强度，且物料不分层，是制药厂理想的物料输送设备，同时在化工、轻工食品等行业亦可广泛使用。

It has thus been demonstrated that a tiered approach at all three steps can be helpful to optimize the use of the available resources; if relatively crude tools –designed to provide a "worst case" estimate –do not suggest a toxicologically significant exposure( or a relevant deficit of a particular nutrient) it may not be necessary to use more sophisticated tools.

已经证明，在所有的三个步骤中一种分层的方法能够有效优化可用资源：如果一种相对粗糙的方法――设计用来对最坏的情况进行评估――没有显示有毒理学意义的暴露（或者某种特定营养的不足）――那就不需要再使用更精确的方法。

Model NTY series mobile lifting charging machine is mainly applied in conveying, lifting and charging for powdery and granule material in pharmaceutical enterprises. It can be combined with mixer, granulator, tablet compressing machine, capsule feeder. With the optimum technological process, the pollution and dust are decreased efficiently and the labor intensity is reduced. It is an ideal equipment for enterprise to carry out the GMP production and management.

NTY 系列移动提升加料机主要应用于制药企业的粉状，颗粒状等固体物料的输送，提升和加料，可与混合机，制粒机，压片机，包衣机，胶囊充填机等主要工艺设备配套使用，可优化生产的工艺流程，有效地减少了交叉污染与粉尘飞扬，减轻了劳动强度，且物料不分层，是制药企业实现符合 GMP 生产的理想物料输送设备。

In this model, PCA is applied to feature selection, and Multi-layered SOM is designed to subdivide the imprecise clustering in single-layered SOM layer by layer.

模型运用主成分分析算法对输入样本进行特征约简，运用分层思想对分类精度低的聚类进行逐层细分，解决了单层自组织映射分类不精确的问题。

The result shows that the incorrect planar overlap is one of the most important factors, which cause layer separation.

研究结果显示：面重叠率不正确为工件发生分层的众多原因中，最直接的影响因素。

The scheme has the structure of hierarchical PKGs, so a lowerlevel PKG can share the workload of secret information generation and identity authentication with a higherlevel PKG. At the same time the scheme has the property of proactive security, that is, the whole lifetime of signature is divided into several time periods, and the shares of private key need to be renewed in each time period. However, new shares can construct the same private key as old shares.

方案具有分层的PKG结构，低层PKG可以分担高层PKG的秘密信息产生和身份认证的任务；同时具有动态安全的特性，将签名的整个生命周期分成若干时间段，每个时间段都对密钥份额进行更新，更新后的份额重构的密钥保持不变。
