查询词典 switches

The proposed inverter has a new auxiliary resonant commutation cell. It provides that all main switching power devices in the soft-switching inverter operate at zero-voltage-switching turned-on and the auxiliary switches operate at zero-current-switching turned-off. In addition, this thesis presents an improved control scheme to minimize the operation of auxiliary resonant circuit for efficiency improvement.

所研制之柔切式数位变流器，系利用新型辅助谐振单元，使主功率开关操作於零电压切换，辅助开关操作於零电流切换，在此也提出改善之控制方案，以避免多余的辅助开关切换，因此能有效降低谐振电流所造成的额外导通损失，以提升系统之效率。

Switches are available for vertical or underhung mounting in voltage ratings of 7.5, 15, 23 and 34 kV; 600 and 1200 amperes.

开关有垂直或倒挂式安装，电压等级为7.5，15，23和34千伏，电流为600和1200安培。

A: I will probably adjust the voting rules for it in 6.60 so there are fewer undesired switches going on.

答：我可能会调整的投票规则，这在6.60 ，所以比较少不受欢迎的交换机进行。

Organic photochromic materials are potential and practical in the areas of photochromic storage,mo- lecular switches,camouflage materials,and so on,but their unideal thermal stability has been barricading their marketing.

thermal stability ；有机光致变色材料在光存储、分子开关及伪装材料等领域具有潜在应用前景，但热稳定性不足一直是制约其市场化的主要障碍。

The basic concept of the proposed scheme is to find the union sets of the output ports of switches in the paths between the source processing node and each destination processing node in the multicast group.

我们所提出机制的基本观念是找出介於来源结点与在多点传播群组结点中，所经过交换器的输出埠联集集合。

A unique identifier is placed in the header of each frame as it is forwarded between switches D.

在两个交换机间传输FRAME的时候，用来区别在此FRAME是那个VLAN的。

Through such a study, it is also shown that when the time delay is long enough such that the stability switches of the equilibrium of system halt, the bifurcation branches originated from the critical time delays cannot be surely stable or unstable in the whole solution space, that is, their stability depends on cases.

利用打靶法的数值结果说明了当系统平衡点不再发生稳定性切换时，源自这些临界时滞处的解支的稳定性在整个解空间的稳定性具有不可判定性，这也说明由多尺度法所得高阶近似判定的解支的稳定性事实上只表示解支在局部中心流形上的稳定性，而非在整个解空间中的稳定性。

On some cars, the upshift and downshift operations can also be commanded by pushbuttons or rocker switches installed on the steering wheel with an optional display in the instrument panel indicating the current gear selection.

在一些汽车中，升挡和降挡的操作也可以由装在方向盘上的按钮或拨杆开关来完成，在仪表板上的选择性显示器指明当前的挡位选择。
