交换

Rotary's Youth Exchange program allows Rotary districts to participate in exchanges with students ages 15–19 from more than 80 countries worldwide.

扶轮的青少年交换计划能让扶轮地区参与全世界80个以上的国家15到19岁的学生参加交换活动。

By using properties of scalar matrices over semirings,we generalize algebraic properties for the automorphisms of matrix algebras over commutative rings and obtain some algebraic properties for the automorphisms of matrix algebras over commutative semirings.

在这一章中，我们首先利用半环上常量矩阵的性质把环上矩阵代数的性质拓广到半环上，获得了交换半环上矩阵代数自同构的一些代数性质，接下来采用积和式的方法证明任意非负交换半环上n阶矩阵代数Tn的自同构的n次幂必为内自同构。

During incubations, significant uptake fluxes of NO(superscript - subscript 3) and SiO(superscript 2- subscript 3) were commonly shown at the sediment-water interface, and largely controlled by their concentrations in the overlying water. The molecule diffusive fluxes, calculated from the concentration gradients between overlying water and surface pore water, seemed not so important in the exchange fluxes.

沉积物－水界面交换过程在春季表现为对NO(上标-下标 3)和SiO(上标 2-下标 3)的吸收，吸收的量在很大程度上取决于上覆水中这两种营养盐的浓度；由上覆水和表层间隙水浓度梯度所决定的分子扩散通量对实际交换通量的控制有限。

TCP segments are assembled into an OBS burst at the edge of an OBS network.

TCP/IP分组在光突发交换网络的边缘汇聚成突发，突发通过OBS网络交换。

Anion exchange resin ; glycidyl methacrylate ; divinylbenzene ; porogenic diluent ; exchange capacity

阴离子交换树脂；甲基丙烯酸缩水甘油醚；二乙烯基苯；致孔剂；交换容量

It is Radiant and there is a goodly exchange of information within the particulates of this radiation and the Cosmos.

它是向外辐射的，并且，这是一个出色的信息交换－－在辐射微粒与宇宙之间的信息的交换。

In High-avail, made a concept of Redundancy Manager, and put forward some ethernet ring structures on the base of it. We can find these meet different levels of Avail requirement. In Real-time, it made great improvement on traditional ethernet. Adopted switch technology, high-speed ethernet, full-Duplex port switch, data prioritisation, and VLAN technology.

在高可靠性方面，提出了冗余管理器的概念，在它的基础上形成的几种以太网环网结构，可以满足不同层次的可靠性要求；在实时性方面，对传统以太网加以改进，采用了交换技术、高速以太网技术、全双工端口交换的方式、优先级标志技术、虚拟网技术等新技术。

Through an examination of mentoring support among mentors and proteges, we found that exchange behaviors were clearly influential on met expectation and perceptions of relation effectiveness, which includes relation satisfactions and competency, and trust.

本部分运用社会交换理论思路，从最基本的心理视角出发，研究了指导过程中管理指导交换之机制。研究发现，指导支持行为和期望满足及关系效能感（包括关系满意感、关系胜任感和信任感）之间存在积极关系，期望满足在指导行为和关系效能感的大部分因素之间起着中介影响作用。

Since there is currently neither have a swappable trait or concept for allocators this implementation always performs a slow swap.

由于当前对于分配器还没有一个'可交换' trait 或概念，所以这个实现总是执行慢交换。

Since there is currently neither have a swappable trait or concept for allocators this implementation always performs a slow swap.

由於当前对於分配器还没有一个'可交换' trait 或概念，所以这个实现总是执行慢交换。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
