One is successive continue to hold a title 10 years homebred server market manufacturer of the first old brand IT, another is the provider of server core technology of the first of all on international, both strong strong together and high-key show a person, its intention lets person ponder quite. On November 28, tide of the first brand enters homebred server to be created by Intel skill " value of server industry core is encircled ", this contains the strategy to form an alliance colorific is global " wealthy person club ", open wide a gate to meet the member that comes from China for the first time.

一家是连续10年蝉联国产服务器市场第一名的老牌IT厂商，另一家是国际上首屈一指的服务器核心技术提供商，两者强强联手且高调示人，其用意颇让人玩味。11月28日，国产服务器第一品牌浪潮闯入由英特尔一手缔造的"服务器产业核心价值圈"，这个带有战略结盟色彩的全球性"富人俱乐部"，第一次敞开大门迎接来自中国的成员。

This paper discusses the operable methods of managing core competence based on the comprehension of the theory of core competence.

本文试图从核心竞争力的基本理论出发，对核心竞争力培育和提升的可操作性途径进行系统性探讨。

Firstly, we introduce two reference frame used in the model: the earth's core orthogonal reference frame and the station's core horizontal orthogonal coordinate system.

首先，介绍了用到的两个坐标系：地心直角坐标系和站心地平直角坐标系。

In the parallel program, the in-core and out-of-core algorithms can be identified and chosen to use automatically. So the algorithms are united.(3) The re-orthonormalization technique is used to solve the loss of orthonormality of basis vector during the classical GMRES method solving large-scale three dimensional elasto-static BE problems.

3采用重正交技术解决了经典GMRES方法在求解大型三维弹性静力边界元问题过程中出现的基向量正交性丧失的问题；结合边界元基本解和系数矩阵的特点以及并行化的要求，研究了几种预条件技术；并以重正交技术和预条件技术实现了经典GMRES的实用化。

In addition, after comparing the time difference between the precursor and the main PKKPbc phase at different outer core conversion point positions, we find the seismic evidence for the tangent cylinder structure in the outer core.

4通过对PKKPbc波形及其前驱波的分析，得到了外核顶部轻元素组成的刚性薄层的地震学性质：我们还通过比较不同位置的前驱波到时的差异，提出了外核可能存在tangent cylinder结构的地震学证据。

With temperature increasing, granular outshoot prefer to grow along with vertical direction of surface of BN core, as well as the wrapped leaf-like shape form from granular ones. And the productions always kept complete morphology of sphere, which was due to the uniform growth of fluffy film on the BN core. Wrapped leaf-like structure of BN piece in fluffy film favored increasement of measured surface area and elimination of oxygen element.

凝并在球核表面的中间产物受到初始BN球核在空间上的诱导作用，随着温度的升高，突出物倾向沿着垂直于球面的方向向外生长，形貌由普通的粒状转变为卷叶状；绒膜的厚度均匀一致，产品得以保持规整的球状形貌，绒膜中卷叶状的BN结构利于氧杂元素的脱除，同时增加了比表面积。

The outturn rate of corrugating core is 60%~85%, while 100% for concave-convex core.

二瓦楞芯层出材率60%-85%，而凹凸芯层为100%。

Joe Pantalone, Alcan Baltek's market manager, reports that Navy engineers selected balsa core because they learned early in their evaluation of composite materials that "the mechanical properties of balsa as a core material compared to its cost are significantly better than any other material."

Alcan Baltek公司市场部经理Joe Pantalone报道说："美国海军的工程师之所以选择巴沙木作为夹心材料，是因为他们在早期的复合材料评估中了解到，巴沙木的机械性能的性价比远高于其它材料。"

Pachomius manual labour was organized as an essential part of the monastic life; and since it is a principle of the monks as distinguished from the mendicants, that the body shall be self-supporting, external work of one sort or another has been an inevitable part of the life ever since.

根据圣pachomius体力劳动组织作为一个重要组成部分寺院生活；以来，这是一个原则的和尚，作为有别于乞丐，该机构应自支撑，对外工作的这种或那种已一个必然的一部分，生活至今。

In order to study the effects of parametrical rolling on the ship movement and tilts, in allusion to ship's navigating in regular following waves, the equation of ship rolling motion is transformed into normal Mathieu equation by proper variable replacement when strong parametrical excitation in restoring moment varied according to sine or cosine wave.

为研究参数横摇对船舶运动和倾覆的影响，通过对船在规则波上随浪航行时，恢复力矩中出现的1个以正余弦规律变化的强参数激励项进行适当的变量置换，将船舶的横摇运动方程转换成标准形式的Mathieu方程。
