Then, the high and low tidal levels for engineering design were calculated based on the predicted results, and the tidal level corresponding to the cumulative frequency 99% of hourly-varied data series of tidal levels accorded with that corresponding to the cumulative frequency 90% of the data of low tidal level.

利用预报结果计算了工程设计高、低潮位，时序潮位累积频率99%对应的潮位与低潮位序列数据累积频率90%对应的潮位一致。

The quaternion signal model was constructed through the separated signal and its Hilbert transform. The corresponding four order cumulant was defined to restrain the additive Gauss noise and the frequency was extracted using the properties of Hamilton quaternion and hypercomplex.

并根据该模型利用特殊的四阶累积量切片分析了加性高斯有色噪声中二维谐波频率估计及联合Hamilton四元数和超复数在二维谐波频率估计中的应用前景。

AML patients with FLT3-LM was associated with a higher peripheral white cell count and a higher percentage of bone marrow blast cells but no lower complete remission rate tendency or shorer survival time camparing with FLT3-LM negative patients.

FLT3长度突变是AML中发生频率较高的一类突变；突变患者临床特征表现为外周血高白细胞，骨髓高原始细胞；FLT3长度突变与诱导缓解率和总生存时间无关。

Behavior of lying-on-the-bed and side-lying, abdomen-contracting and cub-licking were frequently happened, which accounted for 20.41%、13.36% and 21.48% respectively, more than half of the whole activity.

雌虎在产床上躺卧、侧卧努责和舔仔行为发生频率比较高，频率分别达到20.41%、13.36%和21.48%，总和达到了所有行为频次总和的一半以上。

Its final target is to fully digitize the analogue receiver. The all digital receiver not just means digitizing every unit of the analogue receiver, but is a new receiver architecture. The two outstanding characters of this new architecture is: 1 It uses a high stable oscillator to generate a fixed frequency source. And both the sample signal and the local carrier required are obtained from it. 2 Once the received signal has been sampled by a high speed A/D converter, some digital signal processing algorithms will be used to realize all further processes, such as digital down-converting, match filtering, symbol timing, channel equalizing, carrier synchronizing, demodulating and decoding.

全数字接收机并不是简单地将传统的模拟接收机中所有的部件数字化的结果，而是一种全新的接收机体系结构，这种新的体系结构具有两个最为突出的特点：1）采用高稳定度晶体振荡器产生一个固定的本地频率源，接收机中所需的采样时钟信号和本地载波均从这一固定频率源得到；2）接收信号一旦经过高速模数转换后，余下的工作如频率变换、匹配滤波、定时同步、信道均衡、载波同步、符号解调、判决与译码等全部由数字信号处理算法来实现。

It is found that there exist quasi-45 d,quasi-23 d and quasi-14 d low-freque ncy precipitation over the plateau and that the lower of the frequency,the more likely of their propagation from south- and east-side of the plateau to the pl ateau itself,and v.v.

研究表明，准45 d、准23 d和准14 d等3类低频降水的频率愈低，低频降水愈趋向于从高原东侧和南侧向高原传播；反之，频率愈高，低频降水愈趋向于由高原向高原东侧和南侧传播。
