静态

Firstly the k-e two-equation turbulence model is used in numerical simulation of the flow field ,compared with the practical measures and tests, good accordance achives. This method can bring great convenience in analyzing aerodynamical field of boiler. Secondly the method of ash-composition, ash-melting-point, XRD is used in analyzing the phase transformation in the course of dynamic slagging test, so we can describe the process of slagging comparatively accurately. Last this paper introduces a kind of fuzzy mathematics model which comprises an assemblage combined by seven change factor.

接着采用标准k—ε双方程模型对炉内冷态空气动力场进行了数值模拟，并与实际锅炉燃烧器冷态调试试验结果对比，结果吻合较好，这为我们分析炉内流场提供了参考；其次对锅炉静态、动态特性试验，采用灰成分分析、灰熔点测试及X光衍射物相分析方法，较为准确的描述了实际锅炉结渣过程；为了准确的判断出水煤浆的结渣倾向，本文对锅炉结渣的七个影响因素提出了模糊综合判断模型，正确的反映出了该水煤浆的结渣倾向。

1 Class A: FREE BALLOON -An aerostat, supported statically in the air, with no means of propulsion by any power source.

A 级：自由气球—浮升器之一种，未使用任何动力源推进，得以静态支持在空气中。

The two results are very close and in the static state they show good agrement with the actual situation of the slope, provig high accuracy of the present model test and numerical calculation.

两者规律一致、结果相近且在静态情况下与现场实际相符，证明本文模型试验与数值计算的正确性。

This is followed by cooling in still air to at least some temperature well below its transformation temperature range.

这个在当温度低于转变温度的时候也会伴随着静态空气冷却。

This paper studied the frequency response of hot-film air mass flow sensors by the theoretical analysis and experimental research methods.

应用理论分析和试验的方法，研究了热膜式空气质量流量传感器的静态响应和动态响应特性。

A static finite element model of an air spring was given.

摘要文中建立了空气弹簧的静态有限元模型。

Although the quality and quantity of mobile anti-aircraft gun systems remains unknown, there is no indication of any mobile surface-to-air missile systems other than man-portable systems such as the SA-7 and SA-14 or SA-16 entering the inventory to augment North Korea's static air defense umbrella.

虽然质量和数量的移动高射炮系统仍然未知，目前并无迹象显示有任何的移动型防空导弹的系统以外的其他单兵携带系统，如的SA - 7和SA - 14或SA服务-16进入库存，以加强北朝鲜的静态防空保护伞。

According to the failure style of the air valve of industrial compressor,the fracture and static stress are analyzed.

针对工艺用压缩机气阀的失效形式，对损坏的阀片进行了断口及静态应力分析。

By August, the 8RJ2B had logged 559 hours in the air, 2104 hours on the whirlstand, and 1545 hours in free airstream static tests.

到8月份，8RJ2B已记录在空气中，2104小时的whirlstand五百五十九小时，并在1545小时免费性气流静态试验。

Up to now, the performance index is almost described as an algebraic function of manipulating variables, it implies the response of performance index to the manipulating variables is instantaneous or the system is in steady state, and the effects of disturbances on the objective function are not taken into consideration.

在以往的工作中，大都把过程的调优变量与目标函数之间的关系用代数方程描述，这意味着目标函数对调优变量的响应是瞬时的，或假定过程处于静态，而且一般也不考虑过程中其它干扰对目标函数的影响，即在算法结构中，调优变量与目标函数构成唯一的因果关系。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
