Last table 2 and table 3 " line in morning " refer to line coordinates longitude in morning, equal 180 °-t; " dusk line " refers to dusk line coordinates longitude, equals 180 °+t.
During the graticules of dish, the longitude clockwise direction is 0 ° to 360 ° of a hour angle round the clock in design, and when 0 ° of warp was midnight 0,0 o'clock clockwise hour was 0 up to 24 o'clock constantly.
The longitude that graticules is coiled in design round the clock, according to every 15 ° be one hour, can extrapolate morning line and dusk line hour constantly.
March 21 23 (Autumnal Equinox) to next years of September (Spring Equinox), the terminator coordinate longitude of each latitude of the Northern Hemisphere adopts the corresponding terminator coordinate of table 3 the Southern Hemisphere same latitude longitude, and the terminator coordinate longitude of each latitude of the Southern Hemisphere adopts the corresponding terminator coordinate of table 2 Northern Hemisphere same latitude longitude.As Dec 22 be the winter solstice, the Northern Hemisphere with the terminator longitude of number of degrees latitude with the terminator longitude that is the identical number of degrees latitude in the Southern Hemisphere of summer solstice on June in the table 3 22; And the Southern Hemisphere with the confused linear longitude value of number of degrees latitude with the confused linear longitude value that is the identical number of degrees latitude in the Northern Hemisphere of summer solstice on June in the table 2 22.
Dec 8 was that day in Great Cold or January 5 are the little day of snow, the Northern Hemisphere with the terminator longitude of number of degrees latitude with being on June in the table 35 day in Grain in Ear or July 7 to be the terminator longitude of the identical number of degrees latitude in the Southern Hemisphere of day in Slight Heat; And the terminator longitude of the identical number of degrees latitude in the table 2 summer solstice Northern Hemisphere is used in the Southern Hemisphere with the terminator longitude of number of degrees latitude.
The terminator longitude on other dates is so analogized.Perhaps by formula
The longitude and latitude coordinate figure of the terminator of extrapolating.
According to formula
The longitude and latitude coordinate figure of the terminator that can extrapolate, so that the terminator that draws, table 4 was the concrete longitude and latitude coordinate figure of summer solstice terminator for June 22.
Table 4 summer solstice (June 22) terminator longitude and latitude coordinate figure (longitude and latitude unit: °)
With the coordinate figure of longitude and latitude shown in the table 4, can directly draw out the terminator 302 shown in Fig. 7.
As shown in Figure 7, on the graticules, warp start line numerical value is 0 °, and it is 360 ° that clockwise direction is measured a week.Angular coordinate time spent when warp is made terminator, 0 ° of actual clock at zero point that equals the earth of line, 0 °～360 ° are equivalent to 0 o'clock～24 o'clock hour, and 15 ° is 1 hour, and 1 ° is 4 minutes.
As shown in Figure 7, the main latitude and longitude coordinate point of terminator is marked on graticules, be linked to be smooth curve then.This is the described terminator of this practical embodiment.
Coil 30 round the clock and be provided with 13 terminators, wherein, June 22 was to be a terminator summer solstice, Dec 22 was to be a terminator winter solstice, January 20 was day in Great Cold and November 22 to be to be the little day of snow terminator, February 5 was day in the beginning of spring and November 8 to be to be a terminator day in the Beginning of Winter, February 19 was rainwater day and October 23 to be to be a terminator day in the Frost's Descent, March 5 was day in the Waking of Insects (3rd solar term) and October 8 to be to be a terminator day in Cold Dew, March 21 was day in the Spring Equinox and September 23 to be to be a terminator day in the Autumnal Equinox, promptly clear and bright day of April 5 and September 7 are to be a terminator day in White Dew, April 20 was that day in grain rains and August 23 or day in the Limit of Heat are a terminator, May 5 was day in the Beginning of summer and August 8 to be to be a terminator day in the beginning of autumn, May 21 was Grain Full day and July 23 to be to be a terminator day in Great Heat, June 5 was day in Grain in Ear and July 7 to be to be a terminator day in Slight Heat, and January 5 was day Slight Cold and Dec 7 to be to be the big day of snow terminator.
Because the terminator and the terminator in Dec 7 or January 5 in June 5 or July 7, the terminator in its too close respectively place June 22 and Dec place on the 22nd terminator, for card is clean and tidy round the clock, can omits and not draw.So, generally also can use 11 terminators, shown in Figure 6 as this practical embodiment, that is: June 22 was to be a terminator summer solstice, Dec 22 was to be a terminator winter solstice, January 20 was day in Great Cold and November 22 to be to be the little day of snow terminator, February 5 was day in the beginning of spring and November 8 to be to be a terminator day in the Beginning of Winter, February 19 was rainwater day and October 23 to be to be a terminator day in the Frost's Descent, March 5 was day in the Waking of Insects (3rd solar term) and October 8 to be to be a terminator day in Cold Dew, March 21 was day in the Spring Equinox and September 23 to be to be a terminator day in the Autumnal Equinox, promptly clear and bright day of April 5 and September 7 are to be a terminator day in White Dew, April 20 was day in grain rains and August 23 to be to be a terminator day in the Limit of Heat, May 5 was day in the Beginning of summer and August 8 to be to be a terminator day in the beginning of autumn, and May 21 was Grain Full day and July 23 to be to be a terminator day in Great Heat.
Above-mentioned terminator generally is applicable to the mechanical clock real time display tray.
When terminator 302 according to formula
Calculate or according to formula
When calculating the t of the length round the clock value of different latitude, can use the terminator of real-time change every day, line overlapped the moment switching when its terminator was the international date line of dials at that time with dish round the clock zero.The δ value is to overlap the solar declination in the moment from what chronometer data obtained when date modified line line when zero.The switching that for example Figure 8 shows that the terminator on the same day in the Summer Solstice in 24 solar term is the moment switching that overlaps when international date line 428 line 303 with zero time.All the other solar term or date terminator switch and can no longer be repeated in this description at this by that analogy.According to formula
The terminator degree of accuracy of calculating is higher, and every day real-time change, be applicable to that generally electronics shows clock and watch.
