The simulation results show that the performance improvement of proposed algorithm is superior to conventional differential demodulation by 1.4 dB at a BER of 10-4 in AWGN channel.

Thirdly, for differential demodulation, two kinds of timing algorithm and improvements in application are proposed, joint synchronization algorithm and statistical algorithm.

再次，针对差分解调提出了两种定时算法，联合同步法和统计法。

Design of digital filter is an important part in signal processing. The band-pass, low-pass and delay filters are involved in differential demodulation.

数字滤波器的设计是信号处理中非常重要的环节，在差分解调中涉及到带通、低通和延时滤波器的设计。

The paper proposes the application of nonredundant error correction in differential demodulation combined with soft-decision decoding.

提出了结合软判决译码的非冗余纠错（nonredundant error correction）在差分解调中的应用。

We need delivered price for less than $ 0.10 which means your price is way to high.

我们要求含运费价格低于0.10美元,也就是说你们的价格太高.

Therefore, the effect on the breeding and resource enhancement of demersal fishes brought by freshwater snail cannot be ignored.

因此，螺类对产粘性卵的鱼类的繁殖和资源增殖所带来的影响不容忽视。

Theory of demand-pull inflation

需求拉动通货膨胀理论

The result indicate the causes of China technology markets growth is demand pull not technology push.

结果表明：中国技术市场规模扩张的类型属于需求拉动的规模扩张，而不属于技术推动的规模扩张。

Demand pull factors: Factors that attract migrants into another country.

需求拉动因素，吸引因素：指吸引移民到另一个国家去的因素。

Enhancement of China Innovation Capability: From Technological Diffusion to Demand Pull

中国技术创新能力提升：从技术扩散到需求引致

The motivation is demand pull and science and technology push;

需求拉力与科技推力是发展的动力；

Conclusions Denticulate ligament was a mark and could be used to identify and localize the spinal nerve anterior and posterior roots in the SPR or SAR, especially for the cervical nerve roots.

结论在选择性脊神经根切断术中，齿状韧带可作为一标志，脊神经前、后根可通过齿状韧带加以鉴别和定位，特别在颈部。

Results: The ventral roots lay in front of the denticulate ligament, while the dorsal one behind it.

结果：臂丛前后根之间有齿状韧带相间隔；

Methods The denticulate ligament was observed and measured on 30 adult specimens.

方法对30例（60例）成人尸体的齿状韧带进行了解剖学观测和测量。

CT scans showed bilateral symmetrical hypodensity foci in lenticular ( 5/ 7), head of caudate nucleus ( 4/ 7), thalamus ( 2/ 7) and dentate nucleus ( 1/ 7).

双侧豆状棱（5/7）、尾状棱头部（4/7）、丘脑（2/7）及齿状核（1/7）对称性低密度区和与年龄不相符的脑萎缩。

Conclusion In the early stage, MSA is shown the degeneration of neuron is mild, and the lesion of axon is the main pathological changes. The PV (+) neuron in the dentate nucleus may due to the cell protective reaction.

结论MSA早期小脑的病变是以轴索病变为主而神经元变性则较轻，并且在齿状核出现的PV（+）神经元可能是一种细胞保护性反应。

From 32 rhesus monkeys the vermis cerebelli and the portion containing the dentate nucleus were fixed in 10% formalin. The animals of both sexes were divided into 4 age groups according to their dental status.

用狝猴32只，分雌雄两批，按齿序情况分为4个年龄组。取小脑蚓体及含齿状核的部分，用10%福尔马林固定，作石蜡切片及少量冰冻切片。
