Secondary axes

To Create a Chart with a Secondary Y Axis (two different Y Axis scales and the same X Axis) 

Select all data series to be plotted (the X Axis data series, two Y Axis data series). 

Click on the data series whose axis you want to change. 

Press the Secondary Axis button. A preview of the combination chart will be displayed. If the chart is suitable, press the OK button. 

To produce an XY chart with two different X axes and two different Y axes, you must create a chart with one set of x and y data series, then paste the second set of data in the chart, then designate the series to be plotted on the secondary Y Axis and the secondary X Axis, as described in the following box.

All the possible combinations of these symmetry elements result in 32 crystallographic point-group symmetries or crystal classes their symbols are listed in Table 3.3. Notice that in putting together the symbols to denote the symmetries of any crystal classes the convention is to give the symmetry of the principal axis first for instance 4 or 4, for tetragonal classes. If there is a plane of symmetry perpendicular to the principal axis, the two symbols are associated as in 4 m or Aim (4 over m), then the symbols for the secondary axes, if any, follow, and then any other symmetry planes. In a symbol such as Almmm, the second and third m refer to planes parallel to the four-fold axis. 

Secondary axes may be in sets, but there is no need to mention more than one. Thus if, to a principal fourfold axis, we add a Secondary twofold axis (perpendicular to the principal axis), the action of the fourfold axis inevitably creates another twofold axis at right angles to the first and further we find that there are inevitably two more twofold axes bisecting the angles between the first two. This is illustrated in Fig. 30, a stereographic projection in which a point represents the pole of a general plane if A is the secondary twofold axis which is first introduced, the direct action of the fourfold axis is to create another...

Excel can plot several data series in the same chart (the upper limit is 255 data series in a chart see "Some Chart Specifications" at the end of this chapter). If the values in the data series are similar in magnitude, then plotting two or more sets of data is not any different from plotting one set. If the numbers are very different (for example, if one set of y values is in the range 1-10 and the other set is in the range 0.001-0.010), you must use a chart with a secondary axis (see "Charts with Secondary Axes" later in this chapter). 

Figure 24.7 shows the mass scattering efficiency of the three sulfate aerosols at four relative humidities averaged over the solar spectrum as a function of particle size. The primary label represents the moles of sulfate per particle the secondary axes are the dry particle radius, given by...

Particle dry radius, RP0 (evaluated as the radius of the sphere of equal volume) is also shown by means of the secondary axes.

Die casting is used to make a solid object, but hollow objects cannot be produced by this method. Hollow objects such as balls and dolls are made by rotational casting. The resin and curative mixture is placed in a hollow mould that can rotate simultaneously along the primary and secondary axes. The resin takes the shape of the mould. The shape is fixed due resin curing under rotation at elevated temperature. The mould is then cooled and opened to remove the product. 

Subterminal branches are sympodial branches that develop just below a terminal gynoecium or androecium. Subterminal branching is especially common in acrocarpous mosses, and in many groups most of the shoots are just a series of subterminal branches (e.g., Pottiaceae, Grimmiaceae). Subterminal branches, or secondary axes from the basal part of perichaetia in cladocarpous mosses, are present in many members of the Hypnales (La Farge-England, 1996), but their role in the plant architecture is almost never comparable with that of ordinary branches.

Although the mocUQoatioiis in this system usually occur in the direction of the simary axis, it sometimes happens that they occur parallel to one of the secondary axes. This accounts tor the foct, that some substances, such as felspar, crystallize in fwins vliir are apparently very different (Fi 838 aud 339). Crystals of Glauber salts and oxalic add are found modified in the direction of the orthodiagonal (Figs. 340 and 34L). 

They all crystallise in hexagonal prisms, seen in Figs. Sol to 354, derived from the fundamental form P. The values of the terminal solid angle a, the lateral solid angle and the lengih of the primary axis (c), that of the secondary axes being taken as the unit, are found to be —...

During the process, a number of key factors must be considered to ensure that the process is effective and economic venting is used to ensure that pressure inside the mold is in equilibrium with the external environment release agents must be used for most materials to ensure that they do not stick to the mold surface rotation settings must be carefully selected as the relationship between the primary and secondary axes affects the way in which the material is distributed in the final part and only the external surface of the part is in contact with the mold, particularly in the case of semicrystalline materials, such as polyethylene, which means that cooling rates must be controlled to minimize distortion while accelerating the process.
