Aiming at this problem, we have carried out an experiment on seepage properties for mudstone and argillaceous rock, showed the test result, and analyzed the reason why both the β-factor and the acceleration coefficient are negative. In addition, mistakes often made by some researchers about positive or negative signs before the non-Darcy β-factor were pointed out.

指出一些文献在引用Forchheimer关系时出现的非Darcy流β因子前正负号的错误，给出了非Darcy流β因子和加速度系数出现负值的泥岩和砂质泥岩试样全应力－应变过程中渗透特性试验结果，并对其原因进行了粗浅的分析。

The influence on absorption coefficient brought from shape choice with cylindrical or cone-shaped cavity, square or hexagonal profile, from different closure as air or water, from different material properties and structure sizes, are analyzed based on the numerical calculations. Some general characteristics are summarized. It shows that lowest resonance frequency of sound absorbent coefficient is inversely proportional to volume of cavity and sound absorbent coefficient is proportional to perforated percentage.

2通过数值方法研究了吸声结构内腔为圆柱腔和圆锥腔、基材的剖面形状为正四边形和正六边形、不同背衬、基材材料特性、尺寸大小对整体吸声效果的影响，总结了这些情况下非旋转对称吸声结构的声学特性变化规律，得出腔体体积越大，吸声系数最低共振频率越低；穿孔率越大，吸声系数越大的结论。

The population size of the single non-pollinating fig wasp species hardly shows the negative correlations with pollinator's. The total population size of all NPFWs is positively correlated to the pollinator's. It might be the evolutionary adaptation for coexistence of the many species within a syconium.

自然种群数量分析表明，单个非传粉榕小蜂物种的种群数量几乎不与传粉榕小蜂种群数量呈负相关，而所有非传粉榕小蜂物种的种群个体总量与传粉榕小蜂的种群个体数呈正相关，这可能是多个物种共存于单个榕果内的进化适应。

Jeff George, head of Sandoz, a large generics firm owned by Novartis, a Swiss drugmaker, is convinced that the lure of those growing markets is unleashing an "entirely new dynamic".

Sandoz是瑞士制药商Novartis旗下的一所大型非专利药品生产公司，其总经理Jeff George深信，这些正处上升态势的药品市场正释放出一股全新的活力。

The spread-spectrum code of CDMA isnt orthogonal strictly in a general way because the connection of the stochastic multi-user. The nonzero cross-correlation coefficient will cause multi-access interference.

由于多个用户的随机接入，所使用的扩频码一般非严格正交，非零互相关系数的存在会引起用户间的相互干扰，称为多址干扰。

It is found that amplitude-squared squeezing can be created by 4-photon unitary operator S4 acting on the vacuum state and this shows that the amplitude-squared squeezing can be created by 4-photon unitary operator S4 acting on the vacuum state and this shows that the amplitude-squared squeezing is a new nonclassical effect of light field which is independent of the second order squeezing, antibunching and sub-poisson statistics.

This paper using Zorn Lemma, we get new fixed point theorems for noncom-pact and non monotone operators on Fully regular cones, all the results we get are new.

本文运用Zorn引理，得出了全正则锥上的非紧非单调算子的不动点的存在性结果，这些结论是全新的。

Further more, this method showed that facial swelling could be quantified and was a noninvasive, efficient, reliable and reproducible method of measuring facial swelling following bimaxillary orthognathic surgery.

应用结构光行面部三维立体扫描为一种非侵入性并可重复使用的检查手段，可获得颌面部真实的三维曲面模型；同时利用逆向工程技术和软件可量化测量分析正颌外科术后颌面部肿胀程度和范围；为临床研究正颌外科术后面部肿胀反应提供了一种可靠的研究方法。

There is abrupt phase change in nonsinusoidal waves modulation. It can easily produce impulse current and bring large difficulty to high-power emission system; so it is not beneficial to holding the orthogonality between the orthogonal pulses and demodulating information.

非正弦波调制信号存在相位突变，在工程实践中易产生较大的冲击电流，给大功率发射系统带来较大困难；而且相位不连续也不利于保持正交脉冲间的正交性，不利于信息的正确解调。

Based on the phase-space generating functional for a system with a singular higher-order Lagrangian,the quantal canonical Noether identities under the local and non-local transformation in phase space for such system have been derived.
