Solubility and stability of calcium arsenates under different CO2 pressures are studied based on the data of precipitation and solution experiments simulated by PHREEQC program. The result shows that calcium arsenates can dissolve incongruently by the effect of CO2 in high pH（pH〉8. 3）and make their solubility higher. The higher the CO2 pressure is, the lower the acidity of the incongruent dissolution is.

文章摘要：通过沉淀和溶解两方面的实验数据，应用PHREEQC程序模拟了砷酸钙在不同CO2分压条件下溶解度的变化情况，发现环境中的CO2可使砷酸钙盐在酸度较高（pH大于8.3）的条件下发生不一致溶解，使其溶解度升高；CO2分压越大，砷酸钙盐发生不一致溶解的酸度越低；CO2主要影响3：2和5：3的砷酸钙盐，而对4：2砷酸钙盐的影响较小。

Several factors increase the risk of a first hemorrhage: a small malformation, exclusively deep venous drainage (both of which are easily detected by brain imaging and cerebral angiography), and high intranidal pressure, which is reflected by high pressures in the feeding arteries or restriction of venous outflow.

增加的首次出血风险的几个因素：小的血管畸形，完全是深静脉引流（这两者都很轻易通过脑成像与脑血管造影检测）；高颅压，是由于供血动脉压力增高或静脉引流不足造成。

Cardiac index and intrapericardial, left ventricular end-diastolic, right atrial, and right ventricular end-diastolic pressures were measured during basal state, after fluid overload, and after pericardiocentesis. Twenty-eight patients (57%) had physical signs of tamponade, and 10 (20%) were hypotensive.

分别于基础状态、容量负荷后和心包穿刺后测量心指数、心包内压、左室舒张末期压、右房压和右室舒张末期压。28例患者（57％）有心包填塞的体征，10例（20％）有低血压。

After pericardiocentesis, the intrapericardial pressure decreased (median value,–5 mm Hg; interquartile range,–5 to 0), whereas right atrial and end-diastolic right and left 9 ventricular pressures, although slightly reduced, remained elevated, with a dip–plateau morphology.

在心包穿刺后，心包内压力下降(中位数为-5mmHg，四分位数间距为-5～0mmHg)，而右房压及左室和右室舒张期末压虽然有轻微下降但仍然较高，形态上表现为倾角-平台状。

Pumping Systems—HPLC pumping systems deliver metered amounts of mobile phase from the solvent reservoirs to the column through high-pressure tubing and fittings. Modern systems consist of one or more computer-controlled metering pumps that can be programmed to vary the ratio of mobile phase components, as is required for gradient chromatography, or to mix isocratic mobile phases (i.e., mobile phases having a fixed ratio of solvents). However, the proportion of ingredients in premixed isocratic mobile phases can be more accurately controlled than in those delivered by most pumping systems. Operating pressures up to 5000 psi or higher, with delivery rates up to about 10 mL per minute are typical.

泵系统—HPLC 泵系统通过高压管路和设备将储液系统的流动相按设定的流量精确地输送通过柱子，最新的泵系统由一台或更多的计算机测量控制泵使得流动相组分能够按照程序变化改变比例，如有必要，可以进行梯度洗脱或混合均匀的流动相（i.e。，流动相可以是混合比例的溶液），然而，当操作压力达到或高于5000 psi，流速达到10ml/min的典型值时，预混合均匀的流动相各成分的比例就比泵控制的更精确。

Carmakers are leanly managed and operate under intense competitive pressures even in good times.

汽车制造商的管理不善，即便在光景好的时候，它们也是在顶着激烈的竞争压力运营。

The fundamental force for oil accumulation in the lentoid sand reservoir is the difference of capillary pressures built up between the source rock and the reservoir.

在这类砂岩油藏成藏的过程中，砂体的油相压力要低于与其相邻的围岩中的油相压力，使得砂体成为石油的一个相对的低势区。

Extraction of volatile oil from Ligusticum Chuanxiong was studied in the second section. The experimental results show that 3.7-5.1% extracts can be obtained in temperature ranges from 45 to 65℃and pressures form 30 to 50MPa.

在对中药材川芎单方的药效成分提取的研究中，以收膏率和提取物中阿魏酸的含量为目标函数，研究了单一的超临界CO_2为溶剂的SFE过程中，温度、压力、药材粒度等因素的影响。
