MEFP periodically selects cluster heads according to the node residual energy,incurs low message overhead,achieves fairly uniform cluster head distribution across the network,and the regular node joins the cluster which has the minimal energy-forward among cluster heads,this tactic can avoid forwarding sensing information circuitously.

提出了一种转发能量最小的无线传感拓扑算法MEFP（Minimal Energy-Forward Protocol），算法减少成簇的通信开销，在网络中簇半径区域内仅产生一个簇头，保证了分簇的均匀；在普通节点加入簇的过程中，选择转发功耗最小的簇头加入，避免迂回发送数据，降低了能量消耗。

Celiac were much more than outer stomach in the part recurrence. The Ⅱ,Ⅲ,Ⅳ type were much more in Bormann classification. Low polarization tumors were much more. Part recurrence were less after complete gastrectomy except celiac recurrence. Cardia circumambience and liver-duodenum ligaments (No. 1, 12) lymph node were more in the outer stomach recurrence.

局部复发病例中以腹膜腔复发多见，胃外复发次之；Bormann分型以2、3、4型复发多见；低分化肿瘤复发多见，全胃切除后除腹膜腔复发外局部复发少；胃外复发病例中以贲门周围和肝十二指肠韧带即第No.1、12淋巴结复发多见。

This paper researches linear maps preserving orthogonality,obtains the linear maps preserving othrogonality,it is either a rank -declining or rank -keeping map or a map with nilpotent element in its codomain.

利用分块成向量的方法证明了MnMn(F为域F上所有n×n矩阵构成的乘法半群上的n×n拟正交矩阵组至多含有n个矩阵，利用方程组的解的理论证明了Mn中与给定矩阵A构成两两拟正交矩阵组的矩阵个数不超过n-Rank+1，从而得到Mn上保持拟正交性的线性映射φ要么是降秩的或者保秩的映射，要么φ的值域中含有幂零元。

At present, semiparametric model, functional coefficient model and quantile regression are key issues in the field of regression analysis, they have been applied widely in multi-variable data analysis, economics and finance.

半参数模型、变系数模型和分位数模型是当今回归分析中研究的热点问题，在实际问题尤其是在多变量数据分析、经济学、金融学中有着广泛的应用。

On the other hand, finite difference and finite element methods use bases with small compact support but poor continuity properties.

小波基函数在空间域和频率域中都具有局部性特征，它的性质优于有限差分法、有限元法和伪谱法中所用的基函数。

Each triple corresponds to a single arc in the graph, complete with the arc's beginning and ending nodes (the subject and object of the statement).

每一个三元组均对应于图中的一条弧，且这个弧的起始节点和终止节点分别是陈述中的主体和客体。

In this paper,with the aid of the w~*- sequential compactness of bounded closed balls in the conjugate space of a separable space,we proved that the convex hull of a finite union of bounded closed balls in l~∞ is closed.

借助可分空间的共轭空间中有界闭球的弱星序列紧性，证明在无穷维数列空间l∞中有限个闭球之并的凸包仍为闭集

These theories are mainly: neoclassicism, structuralism, theories of transfer and constringency in neoclassicism and international trade model.

这几种理论分别是发展经济学中的新古典主义典思路和结构主义思路，新古典增长理论中的迁移和收敛理论，及国际贸易模型。

In this paper, we propose a goodness-of-fit for the LCR model. The basis of the proposed test is a contingency table, which groups the population through all possible response patterns and concomitant covariates.The idea is from Hosmer-Lemeshow statistic for the multiple logistic regression model.

这篇论文中我们将提出ㄧ个潜在类别回归模型的适合度检定，此检定的基础是由所有可能回答的选项以及相伴变数分群所组成的列联表，这个概念是由Hosmer与Lemeshow 在逻辑斯回归中所提出来的。

In the thesis, the fundamental formula of FFD method derives from the square root that is approximated by a continued fraction expansion in the one-way wave equation. Optimizations of the parameters of the finite-difference operator improve the validity of the method.

本论文用连分式近似单程波波动方程中的平方根导出FFD算法的基本公式，并对FFD算法中的有限差分算子进行了系数优化，进一步提高了计算的有效性。

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
