大小

Bubble size is a key of evaluating the bubble generation in air floatation technology.

气浮工艺中气泡的大小是衡量气泡制造技术的关键。

The below air bubble or even slightly smaller is just about right.

下面图中显示的气泡大小刚刚好，再少一点点会更好。

Forge company: It has 4 t/3 t electric hammer, 1000 t, 300 t, 100 t/80 t drop press; 450 kg, 250 kg air hammer; heating furnace and other equipments.

该公司拥有1000 t 、300 t 、100 t 、80 t 模锻压力机，4 t 、3 t 电液锤，1 t 、450kg 、250kg 空气锤，大小煤加热炉和煤气加热炉10多台。

The air lock should be of a size which enables the effective surface decontamination of materials being passed through it.

气闸室的大小要满足对通过的原材料的表面进行有效去除污染的要求。

However, increase of heat transfer rate is less than that of air mass flow rate.

与预期相吻合，热传导率的大小取决于气流的制冷率。

The ratio represents the amount of plant air pressure supplied for a given control signal.

这个比率表示对于所给的控制信号而输送的主气源压力的大小。

The air wedge angle can be computed with application of the unitary linearity regress method in fitting the relation between the serial number of the CCD pixels and the serial number of the intensity maximum of interference fringes.

该方法利用待测试件受力产生的形变改变空气劈尖顶角，并用一元线性回归方法对CCD的像元序号与所接收到的干涉条纹光强极大值序号之间线性关系进行拟合，进而确定出空气劈尖顶角大小。

A large range of IRZ and intense fluctuating velocity area around the boundary of IRZ is measured and thought to be important to keep the excellent ignition and combustion characters of the new kind swirl burner. Together with temperature trace method, different structure and operation parameter of the burner are studied in this paper about their effects on turbulent and mixing characters of swirling jet. The structure variation includes different blade angle, use of central gear shape baffle, variable outer length and angle of lean primary air outlet, use of wedge outlet of lean primary air.

采用上述两种测量方法并结合热质比拟温度示踪的方法，本文对径向浓淡旋流煤粉燃烧器喷口结构和气流流动参数的变化对旋流流场的流动、混合、湍流脉动特性的影响进行了深入研究，研究了旋流叶片倾角大小、中心齿型扩锥、淡一次风扩口外伸长度和扩角的变化、淡一次风楔形扩口、直流二次风扩口角度的变化对出口旋转射流流动特性的影响，研究了一次风率和旋流二次风率运行参数变化的影响规律。

It was always here, on the use of Xiankong, the ditch wall repair for a number of private air-raid shelter, size, form different.

有人常到这里，就利用闲空，在沟壁上修了一些私人专用的防空洞，大小不等，形式不一。

Pictured above, the fireball was photographed streaking above Teton mountains behind Jackson Lake, Wyoming, USA. The Great Daylight Fireball of 1972 was possibly the size of a small truck, and would likely have created an impressive airburst were it to have struck Earth more directly.

上面影像拍摄的是火流星在美国怀俄明州杰克逊湖后方的提顿山脉上空。1972年巨大的白昼火流星大小可能类似一辆小卡车，可能会形成一次壮观的空中爆炸，或者直接撞击地球。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
