俄罗斯学者Я.К.拉姆金,在1918年首创的湿度图(湿空气的I-x图)到现在已有三十多年了。这张图不论在化工、热工或保暖通风方面都有很大的用处,替整个工程界节省下来的计算时间真是难以估计。因此,详细讨论该张图的构绘原理是很必要的。虽然各种教科书或专文对这方面已讨论得十分详尽,但在等ф线的问题上,仍有令人不能满意的地方。现提出一点不成熟的意见,试图将等ф线加以修改,尚望各有关方面予以指正。I-x图上的基本参数是热含量I和湿含量x;等x线是一组垂直线,为构绘本图时的基本座标之一;等I线和等x线相交成135°,为作图时的另一组基本座标。按式:
The Russian scholar Я.К. Rumgin, the first humidity map (humid air I-x diagram) in 1918, has been in existence for more than three decades now. This picture is of great use both in chemical engineering, thermal engineering and warmth and ventilation. The time saved for the entire engineering community is hard to predict. Therefore, it is necessary to discuss the principle of the drawing in detail. Although various textbooks or monographs have been discussed in great detail in this respect, there are still unsatisfactory points on the issue of equality. Now put forward a little immature opinion, trying to be amended ф line, is still expected to be corrected by all relevant parties. The basic parameters on the Ix plot are the heat content I and the moisture content x; the x-ray is a set of vertical lines, one of the basic coordinates for the plotting of this plot; the I- Another set of basic coordinates of the graph.
