气压

The pollution flashover accidents take place sometimes in power system and the loss because of which is large, So it is significant to study deeply the pollution flashover performance and DC discharge model of long insulator string at high attitude.

电力系统污闪事故时有发生，且所造成的损失是巨大的，因此深入开展低气压下绝缘子串污闪特性及直流放电模型研究具有重要的学术意义和工程应用价值。

According the result of experiment, the air pressure have effect on flashover voltage, the relationship of the flashover voltage and the number of insulator is linearity, and the change of potential distributing after insulator iced is the main reason why the outer insulation characteristic of iced insulator string declined.

试验研究结果表明，气压对覆冰绝缘子长串的闪络电压影响的特征指数与污秽绝缘子一致，覆冰可认为是一种特殊的污秽形式；在试验研究的串长范围内，闪络电压与串长成线性关系；绝缘子串覆冰以后的电位分布的变化是覆冰绝缘子串外绝缘特性下降的主要原因，但覆冰绝缘子串的局部电弧发展成完全闪络所需的时间比污秽绝缘子长，且受冰层的融化和冰凌状态的影响严重。

The height of the storm surge and the storm current can be seen as two terms. One is induced by the wind stress field, another is inducde by the wind pressure field.

在第三章里，我们忽略了控制方程中的非线性项，将风暴潮潮高和风暴潮流分成气压效应和风应力效应的叠加。

It is necessary to raise steam pressure to open safety valve automatically as to examine its sensitiveness.

1.9 必要时可使气压提高将安全阀自动顶开，以检查其灵敏性。

He did not in fact invent the steam engine as such but in 1769 patented an engine with a separate steam condenser and it was this that proved the breakthrough in harnessing the power of steam for industrial use.

他不仅发明了蒸汽机，还在1769年注册了独立气压机的专利。正是由于这两项突破性发明，推动了蒸汽动力成为工业革命的基础。

Results Sixty per cent cases survived and weaned from MV and extubated within 4-90 days, only 5.9% cases died from shock,ac...

结果显示60％患者在4～90天内撤机并拔管，存活；只有5.9％在1～10天内死于休克、急性肾功能衰竭、气压伤，而另34.1％需要长期MV支持30～2083天（229±136天），最后分别死于医院内感染、营养不良、多器官功能衰竭、MV故障等。

Regular inspection of situation about shut-up of lanes and mining sections, measurement of temperature and draft where self-ignition is possible, regular inspection and measurement of temperature, pressure and component of air around fire area, shall be done.

定期检查井巷和采区封闭情况，测定可能自然发火地点的温度和风量；定期检测火区内的温度、气压和空气成份。

Three regional climate models (MM4,RegCM2 and P-σ incorporated coordinate model)have been used to simulate the regional climate over eastern China in July .It is found that these three models have different performances in simulating different climate elements such as 500 hPa geopotential high field ,temperature fields,sea level pressure and rainy belt location.The results are important for developing regional climate model system which is suitable for eastern China and improving the simulation and forecast results.

利用MM4中尺度数值模式、RegCM2模式和P-σ混合坐标五层区域气候模式，以GFDL多年平均的6月份气候场作初始场，对我国东部地区7月份的区域气候进行数值模拟，比较、检验了三个模式模拟中国东部区域气候的性能，发现对500 hPa高度场、温度场、海平面气压场、雨带位置等不同的模拟对象，三个模式各有优劣，其结果对于发展适合我国东部地区的区域气候模式系统、改进模拟和预测效果具有一定的参考意义。
