Then we use above mentioned theory to study degenerate bifurcations of codimension two in nonlinear oscillator under combined parame-tric and forcing excitation. Thereby stability problems with double zero eigenvalues can be solved.

然后利用上述理论研究了参数激励与强迫激励联合作用下非线性振动系统的余维2退化分叉，从而解决了当解具有两个零特征值时解的稳定性问题。

The topics covered include the basic concepts of information theory--entropy, mutual information, channel capacity, information rate, Shannon's noiseless coding theorem and Shannon's fundamental coding theorem; modeling of information sources--zero-memory and Markov models; modeling of information channels--BSC and BEC channels, additivity of information and cascaded channels; construction of compact source codes--Kraft inequality, compact codes, Huffman and LZW compression codes; and analysis and design of error-control channel codes--Hamming distance, binary linear codes and the parity-check matrix, Hamming codes, checksum codes, cyclic codes and the generator polynomial and CRC codes.

For the data set in this paper, simulation results show that for polynomial orders of less than 7, non-zero coe?

为数据集在本文中，仿真结果表明，对于多项式的订单少于7 ，非零居权证？

At low temperature (700℃), NO〓 emission increases considerably with excess air coefficient, at 800℃ NO〓 emission is almost independent of excess air coefficient, and at 900℃ NO〓 emission is zero indicating that this temperature is the optimal operating temperature.

稀相区出口浓度为零，密相区内NO和NO〓浓度随氧量增加而减少，说明在900℃下，氧量增加促进NH〓(i=0，1，2)对NO〓还原。

The correct answer is "when covered by a film of liquid sufficient to reduce the coefficient of static friction between the tire and the road to essentially zero, but not so deep as to introduce a new source of friction."

正确的答案是"当被覆盖上一层液体足以把轮胎和道路之间的静态摩擦系数减少到理论上的零值又不产生新的摩擦源"。

By adjusting these two parameters, can be near zero coefficient of thermal expansion.

通过调整这两个参数，可以获得接近零的热膨胀系数。

The coercivity of soft magnetic materials is generally near to zero point.

软磁材料的矫顽力一般分布于零点附近。

Rae's voice is almost impossibly gorgeous, effortlessly breathing life into every word. The smooth production recalls the languid, laidback vibe of Zero 7, and indeed the Sia comparisons have already begun, but there's much more to Rae than tasteful 'coffee-table' music.

肯妮贝儿那璀璨华丽的美嗓令人感到不可置信，不费吹灰之力就把栩栩人生唱进歌里的字里行间；她那平滑舒缓的音乐制作风格，令人联想到闲散慵懒之风独具的 Zero 7，相信从此以后会不断的被拿来互作比较；但肯妮贝儿相较於悦耳的咖啡厅音乐，肯定是多了许多音乐内涵的。

Based on the similarity of common reflection point trace gathers in one coherent zone, CRS stack can focus more energy on the vicinity of the reflector, and therefore can obtain a high signal-to-noise ratio zero offset section by stacking events with the same phase.

共反射面叠加利用了邻近多个共反射点道集的相似性，提高了资料的覆盖次数，从而压制了随机噪声，增强反射波同相轴的连续性，大幅提高了地震资料的信噪比。
