Results The high peak and low peak of 24 hour ambulatory blood pressure appeared in the morning and at night in all three groups, but the blood pressure curve was planter in NIDDM and the percentage of disappeared diurnal rhythm of ambulatory blood pressure (blood pressure at nignttime falls less than 10%) was 66%, higher than in EHP (54%) and normal control (50%), the damagement of autonomic nerves appeared in 75%of NIDDM and 69%of EHP, but no relationship was observed between ambulatory blood pressure and urinary protein excretion rates.

结果 三组受试者服药前动态血压皆有昼高夜低的规律，但NIDDM的动态血压曲线更平坦；且昼夜节律消失(夜间血压下降低于10%)发生率为66%，高于EHP(54%)和正常对照组(50%)；NIDDM和EHP组分别有75%和69%的患者出现不同程度的自主神经功能损伤，但动态血压与尿蛋白排泄率间无相关性。

Oscillometric method is the advanced method for the no invasion blood pressure measurement. It qualitatively provides the order of the pulse pressure signal's changing with the cuff pressure and quantificationally points out the relationship between the mean blood pressure value and the pulse wave signal. So this method gives us a more scientific way to find other blood pressure parameters.

The plastic hinge model of perforated liner casing is built up to calculate the collapse pressure according to the strength and deformation behavior of perforated liner casing subjected to external pressure. The calculation equations of collapse pressure of perforated liner casing with initial ovalization are deduced by energy method. The influences of phrase angle, diameter of perforation, shot density, initial ovalization, diameter-thickness ratio and yield stress on the collapse pressure of perforated liner casing are studied. The model and equations are used to calculate the collapse pressure of an actual perforated liner casing as example.

In this paper, two assemblies of special test equipments have been designed and fabricated by authors in our laboratory: namely Catalyst Molding Process Analyzer and Catalyst Mechanical Process Tester. These new skills are developed for the dynamic studies on whole mold forming process and crushing process of Fe-Cr WGHS catalyst pellet. Based on the orthogonal experimental design, the effects of some factors during the forming process of solid catalyst, such as predensification proportion, calcination time, calcination temperature and content of graphite on the mechanical strength of catalyst pellets are systematically examined, and the molding conditions have been optimized. Based on the experimental data, the relationship between catalyst density and forming pressure are educed, and the physical significances of some related parameters are described. The parameter of macro scopic elastic moduls has been suggested to character the mechanical properties of molding catalyst. The effects of molding pressure on mechanical properties of catalyst pellets are discussed, and results show that there exists a optimal molding pressure for the ideal mechanical properties: when over-high or over-low pressure is applied, the specific surface area and side crushing strength of catalyst pellets will decreased. The "rebound effect" will be undermined by the unsuitable pressure maintain process, resulting in the apparent decrease of mechanical strength of catalyst pellets.

The zonality of abnormal pressure is closely correspondent to the breakthrough pressure (or pressure preservative ability) of mudstones in the Dongying Sag. The breakthrough pressures and formation fluid pressure coefficients rise with increasing depth. The preservation of isolated mudstone intervals is also important to the abnormal pressure formation.

东营凹陷异常压力的分带性与泥岩的突破压力具有明显的对应关系，随着深度增加，泥岩突破压力及地层流体压力系数均增大，泥岩封隔层对流体压力的保存也是形成异常压力的重要条件。

When the nozzle pressure ratio is less than roughly one- third of the design pressure ratio, the wake that is present in the base of the plug is said to be "open," meaning that the base is open to the influence of ambient pressure and the base pressure is a strong function of the ambient pressure.
