查询词典 pressures

Thermogravimetric analysis was extended to the measurements on vapor pressures of three n-alkanes, hexadecane, heptadecane and octadecane, on the basis of the Langmuir equation for zero-order vaporization process. The vapor pressures were calculated by two different methods, a constant-parameter one and a comparative one, from the TGA data. These results are in good agreement with the reference data calculated from the Antoine equation.

Following evidences indicate that lherzolite and garnet pyroxenite xenoliths in basalts are captures of mantle fragments when host magma ascending: crystallizing temperatures and pressures of cpx megacrysts and some phenocrysts in host magmas are greater than equilibrium temperatures and pressures of xenoliths; calculated REE partition pattern of assumed equilibrium melts is not comparable with that of studied host basalt rocks; olivine in xenoliths is not in equilibrium with basalt rocks.

寄主玄武岩的单斜辉石斑晶—熔体平衡温度高于石榴石二辉橄榄岩和石榴石辉石岩包体的平衡温度，单斜辉石巨晶和部分斑晶—熔体平衡压力大于包体平衡压力，寄主碱性玄武岩的稀土配分型式和所计算的与尖晶石二辉橄榄岩包体平衡的熔体的稀土配分型式不同，包体橄榄石与寄主岩浆之间的Fe-Mg交换系数低于0.30，均表明包体与寄主玄武岩浆之间不存在平衡关系，因此，包体是被寄主玄武岩浆捕虏的上地幔碎块。

However, there were few reports on the changes in perioral muscle pressures following RME treatment and retention and none domestically.In this study, a new perioral muscle measuring system was invented to measure the values and changes in cheek and tongue pressures before, after treatment and retention in order to supply experiment foundation and theoretical guiding for clinical research and treatment.The study consisted of two parts as follows:In the first part, we invented a new perioral muscle measuring system.

此后学者们进行了广泛的动物实验和临床观察，其中RME的治疗及保持是临床医生非常关注的问题，但RME引起的口周力变化以及这种变化与RME治疗和保持的关系鲜有报道，国内尚未开展此项研究。

The results of simulation indicated that the new model can be applied toany loading condition, describe phenomena that the Terzaghi consolidation modelcan not, such as the apparent preconsolidation pressures that depend on strain rate, increment in apparent preconsolidation pressures due to creep during sustained loading, and change of porewater pres...

计算与实验结果对比表明，该模型能应用于一维条件下任何加载方式的固结模拟，能描述表观前期固结压力的应变率效应、次固结引起的表观前期固结压力增加、连续加载下超静孔隙水压的增长规律等一些已被实验广泛证实且不能被太沙基固结理论反映的现象。

Under confused sea condition, the structures may subject to very strong w ave impulsive 1oad due to slamming by the wave with significant crest when waves propagate underneath the structure and surge up to its subface. Previous studies indicate that impact pressures are characterized by an initial peak pressure of considerable magnitude but of short duration occurs, followed by a slowly-varying uplift pressure of less magnitude but of considerable duration, and which typically is first positive, then decreases to zero and becomes negative, In hostile sea state, the peak pressures may cause the damage of the horizontal members of the structures or make the whole superstructure collapsed.

若这些海上建筑物的上部结构底高程较低，在恶劣海况下当大波浪在其面板下面通过并与之接触时，面板下面除了作用有强度变化较缓慢的波压力外，在波峰刚接触到面板时尚存在着历时很短但强度极大的冲击压力，这种极强冲击荷载会引起建筑物的整个上部结构失稳或造成局部破坏。

A generalized equation of state for liquids at high pressures was proposed based on the Tait equation, and used to calculate the p-V-T data of liquid ethylene at high pressures of up to 130MPa in the temperature range of

提供一个普遍化高压液体的状态方程，并将它应用于计算压力最高达130MPa、温度范围为120K~220K的液态乙烯的pVT数据。

The results show that the effects of pressure on tautomeric equilibrium constant K〓 is very limited at pressures much higher than the phase separation pressures, while the K〓 increases sharply as the pressure approaches the critical pressure or the bubble point pressure of the mixed solvents.

结果发现，在分相点附近化学平衡常数随压力变化十分敏感，这一特殊现象与混合流体中特殊的分子间相互作用与聚集密切相关。

Results Average medial tibiofemoral contact pressures were (4.047±0.217) MPa preoperatively and (3.163±0.438) MPa postoperatively.Maximum medial tibiofemoral contact pressures were (5.455±0.4537) MPa preoperatively and (3.8325±0.6335) MPa postoperatively.
