This class lets you define a mask for a text field. 利用这个类可以为文本域定义一个掩码。
For example, you could use a mask of (###)###-#### so that the user could type only a valid U.S.phone number in the field. 例如,您可以使用掩码()-,使用户只能在文本域中输入有效的美国的电话号码。
For information about input masks, see the article create an input mask to enter field or control values in a specific format. 有关输入掩码的信息,请参阅文章创建输入掩码以便以特定格式输入字段或控件值。
The Input Mask Wizard only works with Text or Date field types. 输入掩码向导只处理文本或日期字段类型。
The input mask is too long for this field. 对该字段而言,该输入掩码太长。
Microwave chamber is an electromagnetic measuring environment that can mask off external interference and restrain internal multipath echoes, while compact field can simulate electromagnetic environment of far field within chamber that is fairly small. 微波暗室是能够屏蔽外界电磁干扰、抑制内部多径反射的电磁测量环境,而紧凑场可以在相对较小的微波暗室里模拟远场的电磁环境。
Based on the digital mask technique, the distribution of sand area density and the sediment-transport rate in flow field were obtained. 采用图像处理的数字掩码技术,处理图像得到了沙粒在流场中的面密度以及单宽输沙率。
Fillet gas mask has the features of comfortable wearing, wider visual field, but complex technology, sealed ability wearing is not easy. 头带式面罩具有舒适性好、视野宽阔,但工艺较复杂、佩戴不易气密等特点。
The paper gives the choice of measurement point and the design project of measurement environment aiming at the problem of sampling measurement in the campus network, and which execute the right priority match sampling measurement about special mask and identification field of IP message. 针对校园网出口流量抽样测量问题,给出了测量点的选择及测量环境的设计方案,实施了特定掩码与IP报文标识字段进行匹配的抽样测量。
Artifact can arise during the construction of the 3D phase mask in regions with severe field inhomogeneity due to the off-resonance effect. 由于梯度回波对磁场不均匀性比较敏感,因此在构建三维SWI相位模板时,某些局部磁场严重不均匀的区域会因为非共振效应而产生伪影。
The results showed that the insert of mask can change output mode of the resonator. This can lead to the formation of multiple Gaussian models output, also the coherence stack can be achieved in the far field, which consistent with the theoretical simulation. 结果表明,掩模板的插入能改变谐振腔输出模式结构,形成多个类高斯模式输出,并且能在远场实现相干叠加,与理论模拟相符合。
