Diaphragm movement in the direction we are through,"Fleming left hand rule"(also known as "motor rule") determined by when the audio signal source is positive when the right side, the diaphragm in the opposite direction and plans, so that when the audio The size of the signal, changing direction, the diaphragm of the vibration on the subsequent non-stop, and its current size of the rate associated with the audio.

振膜运动的方向我们是通过"弗莱明左手定则"确定出来的，当音频信号源右端为正时，振膜的方向与图中相反，这样当音频信号的大小、方向不断变化时，振膜就随之不停的振动，其幅度与音频电流大小相关。

And the key is to take advantage of the physical and chemical properties of shale or mud to enable the shale or mud to form a semipermeable membrane or form a high quality partition membrane on the wall of the well, so as to prevent the mud from flowing into the formation to effectively stabilize the wall of the well and protect the reservoir.

水基钻井液成膜技术是当今研究的热点，其核心技术是利用页岩或钻井液的物理、化学特性，使页岩或钻井液具有半透膜的性能或在井壁上形成一层较高质量的隔离膜，阻止钻井液向地层的进一步滤失，从而有效地稳定井壁和保护油气层。

应用本文研制的化学改性聚酰亚胺膜，研究了渗透蒸发分离过程在戊酸乙酯合成反应中的应用，实验得到的戊酸最大转化率是95.2%，并研究了膜对多元反应物系的选择性，及膜的透过量。

In the inductive period of the polymerization, the rate is proportional to the second power of the potential, but in the autocatalytic period, the rate is only proportional to the potential.

在一系列的聚合电位下制备了聚苯胺修饰电极，得到聚合电位与PA膜电化学性质的关系，达到通过控制聚合电位来得到不同电化学性质PA膜的目的，为PA膜研究中聚合电位的使用提供了较为系统的数据。

Glycerine, triethanolamine, corn starch and polyvinyl alcohol can be immobilized onto BOPP surface using cerous ions as initiator. Attenuated total reflecteion-FITR and CA results show that vinyl monomers also can be grafted onto polymer surface by cerous ion as initiator.

在D-果糖改性CPP膜的体系中，实验结果显示随着D-果糖初始浓度的增加，改性膜的表面水接触角先下降后略微增加；增加紫外光的辐照强度能够促进D-果糖对CPP膜的表面偶合改性。

UV-Vis spectrum showed that some monomer or oligomer were existed in this film. The results demonstrated that the PPy chains were served as both the reductant of chloroauric acid and the ligands to stabilize gold-NPs.

接着利用吡咯单体及寡聚体具有的还原性，将新合成的聚吡咯膜浸泡在氯金酸水溶液中搅拌反应，通过扫描电镜观察发现，在膜中还原生成了大量的金纳米粒子，同时在膜的表面也观察到了金纳米粒子的存在。

The surface pressure-area per molecule isotherm of 0.001molL^(-1) arachidic acid chloroformic solution at the air/liquid interface of pure water has been measured, and dynamic domains morphology of AA monolayer has been investigated via Brewster angle microscopy.

测定了花生酸的氯仿溶液在二次蒸馏水气／夜界面的单分子膜的表面张力与单分子面积的等温线，用布儒斯特角显微镜原位监测了花生酸分子成膜过程中单分子膜区域形貌的动态变化。

AFM, EPMA (Electronic Probe Measurement Analysis) and SEM were used to study the mechanism of bisquats named MDOPD N Metronidazole N (Dodecane 3 Oxal 1,5 Pentanedilamonium Dichloride against Total Growth Bacteria in the culture medium.

研究结果表明：MDOPD能够在培养基中的碳钢金属表面优先吸附，形成完整致密的有机吸附膜，使细菌新陈代谢产物难以到达金属基体表面；同时，MDOPD使生物膜的沉积变得疏松，氧浓差腐蚀和膜下硫酸盐还原菌引起的腐蚀都受到有效的抑制

The hybrid between Brachymystax lenok and Hueho taimen were not a live in the past 2 years. However, the fertility and eyed rate of BH were significantly higher than that of HH and BB (P.05), while the hatching rate were significantly lower (P.05). The larvae died within 1 to 2 hours after hatching. It was observed that the tail of yolk-sac larve couldn't stretch around the yolk, and there were hyperemia in the middle and posterior segment of the tail. The reason why the hybrid between Brachymystax lenok and Hucho taimen couldn't snrvive might was the karyoplasms of the gametes from Brachymystax lerwk and Hucho taimen by distant hybridization were not compatible.

细鳞鲤×哲罗鱿的杂交经过2年多批次实验均未得到成活杂交子代，但在胚胎发育阶段BH的杂交受精率、发眼率均显著高于双亲自繁对照组(P.05)，但其孵化率显著低于双亲对照组(P.05)，BH杂交子代在破膜后1~2h内即死亡，刚破膜的仔鱼尾干中后段至尾鳍部分盘绕于卵黄囊表面不能伸展，且所有破膜仔鱼的尾干中后段均存在充血点，本研究认为，这种反交［细鳞鲑×哲罗鲑］子代不能成活的原因可能是由远缘杂交受精卵核质不相容所导致。

According to the contrast experiment, the ethycellolose film plasticized by glycerin trioleate has the similar mechanic and physical performance to zein film plasticized by 3% oleic acid.

通过与用甘油三油酸增塑改性的10％的乙基纤维素溶液成膜后的性能对比实验，说明3％油酸增塑的zein膜与EC膜的机械性能与物理性质相似。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
