临界状态

Because of attraction between water molecule and carbonium ion, the severe contract in system volume brings about activation volume effect (the most negative A〓 observed in this work is 407cm〓mol〓), which produces subtle relationship between reaction kinetics and pressure in a certain operating region.

反应过渡产物正碳离子及水合正碳离子与近临界状态水分子之间强烈相互吸引导致反应活化体积出现极负值现象（本实验所测极值为-407cm〓·mol〓，这使得水解动力学参数对反应压力存在敏感依赖关系。

Parameters based on chemical shift indicate that methyl is a substituent with electron-withdrawing inductive effect and poor electron-donating conjugative effect. Perhaps its conjugative effect is on critical point. Methyl is electron-withdrawing for benzene relative to H. Otherwise, methyl has strong p-position and weak o-position orientation effect.

化学位移值表示的诱导效应参数表明甲基具有吸电子诱导效应，经校正后的化学位移值表示的共轭效应参数表明甲基具有微弱的给电子共轭效应，甚至其共轭效应有可能正处于给电子和吸电子的临界状态，总之相对于氢原子，甲基具有吸电子效应。

Firstly, pressure, enthalpy, temperature and velocity of pure water at different location of hydrothermal circulation system are described. Density and viscosity of fluid are calculated from temperature and pressure using properties of pure water. Secondly, influences of formational anisotropy and crack zone on hydrothermal circulation are analyzed.

首先讨论了热液循环系统不同部位的压力、焓、温度、水流的密度、粘度及流动速度等参数的特征，其次分析了地层非均质性、裂缝带的存在对热液循环流场的影响，最后分别模拟了近临界状态及侵入体存在情况下的热液循环。

The analysis indicates that the combustion of base bleed charge is in the critical zone between extinguishment and reignition when the base bleed projectile is just out of the gun muzzle.

分析表明，在火炮发射条件下，底部排气弹出膛口时，复合底排药剂燃烧环境恰好处于永久熄灭／熄灭后再复燃的临界状态。

On the basis of other scholoar's research, the author makes systematic、complete and throughgoing research on characteristics and predication of strata movement for the first time in this paper. The creative work makes up land space in domestic and abroad. The author's major work are as follows: 1 According Haken's synergetics view, the author researches the non—linear self —organized evolving process of refeeding, hybriding and cooperating features of internal varables of the roof movement for the first time, and makes an important conclusion that it will appear chaos at the critical state.

本文在前人研究的基础之上，初步用非线动力学的观点，对岩层运动的动力学特征及预测方法进行了较全面、系统的研究，主要工作如下： 1 根据Haken的协同论观点，初步研究了顶板运动过程中系统内部变量的反馈、耦合、协作的非线性自组织演化过程，得到了顶板运动在突变的临界状态呈现出弱混沌性，其力学行为难以准确预测的结论，较好地解释了岩层突变灾害预测困难的内在原因，并为选择合理的预报时刻，提供了依据。

And a method to determine the limit balance status of the slope under explosions based on the plasticity zones transfixion of the slope is proposed. And the factor of safety of the slope is computed using the strength reduction technique and proposed method.

提出了通过分析爆破荷载作用下边坡塑性区贯通与否并辅于边坡关键点位移收敛与否来确定反倾岩体边坡临界状态的方法，并结合强度折减法确定了爆破荷载作用下台山反倾岩体边坡的安全系数。

On the other hand, if your bus timing is marginal, then this technique pinpoints the culprit.

换句话说，如果总线时间处于临界状态，即使很小的调整也会造成系统错误。

On the other hand, if your bus timing is marginal, then this technique pinpoints the culprit.

换句话说，如果总线时间处於临界状态，即使很小的调整也会造成系统错误。

When the injection pressure is about 0.1MPa, the air flow through the injector becomes critical, so if the swirl level variation reaches the required range, the pressure should be kept as low as possible.

空气射束的喷射压力越大，涡流比的变化范围也越大。而当喷射压力达到0.1MPa左右时，空气在喷嘴内的流动已接近临界状态。因此，射束喷射压力不宜过高，在满足涡流变化要求的前提下，喷射压力应尽量低一些。

Lastly, this paper discusses the possibility to monitor the coming of the larger earthquake using shear-wave splitting observation, suggests that the continuous observation on temporal change of shear-wave splitting could be adopted to monitor the occurrence of larger earthquakes, this observation could recognize whether the crust rock has enter the fracture critical state or not, forecast the possible coming earthquake, i.e.

最后，本文对利用剪切波分裂观测对较大地震进行监控作了讨论，认为对剪切波分裂的时间变化作持续的观测，可以进行地震监测，识别地壳岩石是否已经进入了破裂临界状态，对可能到来的地震作出相应的预测。
