And then some ellipses that AUGR estimator is better than the OLS estimator and AUGL estimator is better than the OLS estimator are given, respectively.Second, the definition of the almost unbiased unified biased estimator is proposed. This definition includes the familiar almost unbiased estimators in literatures, and it is the unified expression of the familiar almost unbiased estimators. Followed the biased and variance are compared of AUUB estimator and the unified biased estimator, respectively. AUUB estimator has smaller bias than UB estimator and the variance of AUUB estimator is between the variance of UB estimator and 4 times of the variance of UB estimator. Finally the properties of AUUB estimator are discussed. The conclusion is gained that there are parameters made AUUB estimator is better than OLS estimator in terms of their mean square error. The sufficient and necessary condition that AUUB estimator is admissible is given. The ellipse is given that AUUB estimator is

The results of the simulation analysis and experiments indicate that the loss of ultraviolet scattering transmission in atmosphere is high because of the particle scattering and absorbing in solar-blind zone; that is, the received power can descend 20 dB with the distance increasing 10 times. Therefore, the ultraviolet scattering is fit for short range communication. In short range, the pulse extension due to scattering is at microsecond order and its influence for low and moderate bit rate communication systems is weak. Since the light output power of a single ultraviolet LED is low, a multi-LED array can be used to increase the transmit power and extend the communication range.

仿真分析与实验结果显示:日盲区紫外光在大气中散射传输时由于大气粒子的强烈散射与吸收,传输损耗较大,距离每增加10倍,接收功率下降20dB,因此日盲区紫外光大气散射通信适用于近距离通信场合;近距离传输时散射造成的光脉冲多径展宽为微秒量级,对中低速通信系统影响较小;单个紫外LED发光功率较低,可通过多个LED阵列来提高发射功率,增大通信距离。

On CHE programming, the higher coupling ratio of control-gate makes the higher electrical field across TOX in Si than Ge. Also because of the continuity of displacement vector, the higher permittivity of Ge would cause the lower electrical field at interface. We get the higher gate current in Si than Ge. On CFN programming, the higher CT in Ge would show the higher electrical field across TOX. However, the parameters of F-N tunneling are calculated and showing the gate current in Si is larger than Ge. On the same mechanism of F-N tunneling erasing, the parameters also show the higher electrical filed of Si would cause the higher erasing speed. The continuity of displacement vector also explains the higher electrical field at interface for F-N tunneling programming/erasing.

从通道热电子穿隧写入的模拟结果发现,由於控制闸极耦合电容的影响,加上电位移向量在半导体-氧化层界面连续的观念,拥有较高介电常数的锗反而得到较小的等效电场,决定了穿隧电流反倒是不如矽基板;在F-N穿隧写入的模拟中,即便锗基板拥有较大的总耦合电容,使得在浮闸的耦合电压大於矽基板,但仍旧是半导体-氧化层界面的电场扮演了穿隧电流的决定性因素,得到的结果仍旧是矽基板的写入速度高於锗基板;在F-N抹除的模拟中,运用与F-N写入相同的数学模型,仍旧看见在锗基板上未能得到速度上的改善,同时用数学的计算展示了合理的解释。
