Lest we read too much into INQ's decision, we should recall that the phone maker's devices have limitedcarrier support and are not yet available in the United States.
未免我们过多关注INQ的决定，我们应该记得手机制造商的设备限制载体的支持，这在美国还是不被允许的。

At present, transmitting speed of medium and high voltage power line carrier is very low, and these kinds of carriers can be used only in low speed situation, and the number of user is limited.
目前的中高压电力线载波通信的传输速率都很低，只能应用于低速的场合，用户容量有限。

The electrical potential, field and carrier density in emission layer of single layer organic light-emitting devices are numerically studied based on the trapped charge limited conduction theory.
