分层

Then the problem of diversified goal can be translated into the hierarchical goal programming equivalently.

然后，通过把多目标问题转化为分层目的规划问题对模型进行求解。

Simulation results show that the layered detection and iteration detection algorithms are robust to channel estimation error.

仿真结果表明本文给出的分层检测及迭代检测算法对信道估计误差具有鲁棒性。

The stratified self-calibration based on modulus constraint is used to get 3D information from Euclidean space. And some optimization algorithms are used to reduce error impact.

采用基于模约束的摄像机分层自标定方法得到特征在欧式空间下的三维信息，并通过多种优化方法减少误差的影响。

Positive association were still remained for two locus that MNAT1-rs973063 and PCNA-rs25406 and lung cancer risk even after 1000 times permutation test.During the stratified analysis,we revealed that that several genes in the NER pathway could interact with age,gender,family cancer history and smoking status.

在进行了多重校正后，有两个位点仍显示出关联显著性：MNAT1-rs973063(p=0.02)，PCNA-rs25406(p=0.03)；在随后进行的分层分析中，我们发现NER通路多个基因分别和年龄、性别、肿瘤家族史以及吸烟状况之间存在互作，提示该通路基因位点可能主要是通过和环境交互作用产生效应；我们还进行了单倍型的分析，结果发现PCNA和RPA1两个基因上的单倍型和肺癌易感性相关。

Methods: From May 1985 to December 2002, 2240esophageal and stomach cardia cancer patients treated by intrathoracic esophagogastric "layer-to-layer"anastomosis with esophageal mucosa extended varied in plane were retrospectively analyzed.

回顾性总结1985年5月～2002年12月共进行胸腔内食管黏膜延长不同平面与胃、食管分层吻合术2240例，统计手术后和出院后随访资料发生吻合口瘘和吻合口狭窄的情况。

To evaluate the clinical value of intrathoracic esophagogastric "layer-to-layer" anas tomosis with esophageal mucosa extended varied in plane and to study the effective methods to prevent anastomotic leaking or stricture postoperatively.

目的 评价胸内食管黏膜延长不同平面与胃、食管分层吻合术，探讨预防食管吻合口瘘和吻合口狭窄发生的吻合方法。

From angle of external economy, knowledge spillover and social capital, the paper discusses the relation between corporation cluster, agglomeration economy, city location and development of urban services.

本文从外部经济、知识溢出和社会资本等角度分析了企业集聚、经济集聚状况、城市地理位置与城市服务业发展的关系，并利用分层线性模型检验了集聚效应对服务业差异的影响。

Results MRI findings of central neurocytoma are specific in 5 cases. The ganglioglioma was found in the tempora and occipital lobe in 7 cases,in the brainstem in 1 case, cystic-solid tumor was observed in 5 cases with extramural nodule in 3 cases, obviously thickened gyri were revealed in 1 cases and central necrosis in 2 cases.The 3 cases of Lhermitte-Duclos disease include the specific molecular layer imaging features.

结果 5例中枢神经细胞瘤有一定的MRI特征，3例诊断正确。8例神经节细胞胶质瘤中，7例位于或主要位于颞、枕叶，1例位于桥脑和延髓，表现为囊实性者5例，实性部分位于囊外的有3例，呈实性表现为局部脑回增厚者1例，囊变坏死明显者2例。3例小脑发育不良性节细胞瘤有特征性的条纹状或分层状表现。

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。
