An Explanation of the 90-degree Dial

90dial盘的简单解释

The origins of the 90° dial have been accounted for in various ways by various people.  In the 20th century, according to available documents, the 90° dial was first used by practitioners of Hamburg School astrology, i.e. by followers of the teachings of the innovative astrologer, Alfred Witte.  Ludwig Rudolph, one of Witte's most enthusiastic and dedicated students, used the 90° dial in his astrological practice, as did cosmobiologist Reinhold Ebertin.  Use of such a tool, or the principles it is based on, prior to the time of Witte, Rudolph, and Ebertin is not impossible, yet it is primarly Rudolph and Ebertin who popularized its usage in recent times.

90dial 盘的起源，得从很多人很多方法说起，在 20 世纪，根据可查得文献记载， 90dial 盘最早是被汉堡占星学校中一些有创新精神的占星学家开始使用的， Alfred Witte.  Ludwig Rudolph, 一个 Witte 的粉丝把 90dial 盘用在自己的占星中，宇宙学家 Reinhold Ebertin 也使用这种方法。虽然现在大家都公认这个方法最先是被 Rudolph and Ebertin 普及的，但是要在在 Witte, Rudolph, and Ebertin 的时代要使用这个方法和与之相配套的定理几乎是不可能的。（那时没有计算机帮你）

The underlying principle of the 90° dial is not as complicated as it might seem at first glance.  The dial is based fundamentally on the 4th harmonic, i.e. dividing the 360° circle into 4 equal parts.  360 ÷ 4 = 90.  As borne out by the experience of astrologers over many centuries, 4th harmonic angles, which would correspond with the traditional aspects of conjunction (0°), square (both 90° and 270°, or 90° to either side of 0°), and opposition (180°), were major aspects indicating significant energetic relationships between planets.  While the most dismally traditional astrologers referred to these angular relationships as "malefic" or "evil" due to the dynamic and challenging quality of the interaction between the 2 planets involved, the Hamburg School astrologers and the later Cosmobiologists and Uranian astrologers have continually verified that these are the most energetic angular relationships and therefore of greater significance for personal growth, and for prognosis of significant change and developmental periods.*Considering these observations, the 90° dial was developed in order to:

90dial 盘的基本定理不是那么复杂， dial 是基于 4 倍相位的，把 360 度圆分成 4 个相等的部分 360 ÷ 4 = 90 ，根据占星家们几个世纪的经验，对应传统相位的合相 0 度，刑相（ 90 度和 270 度）和冲相 180 度的 4 倍相位，是行星间非常有力的关键相位，由于产生这这个相位的两颗行星互相改变与挑战对方，许多传统的占星学家会认为这个相位是有害的，甚至邪恶的，汉堡占星学家和稍微晚一些的宇宙生物学家经过长期的经验，认为 90 度相位是非常有力的基本角状（ angular ）角度，所以对个人成长非常有利，对日后的改变与发展非常有利。

1) ease and expedite locating 90° and 180° angular relationships

2) increase × 4 the amount of space between degree markings so that planetary positions could be located visually with greater precision.

3) ease and expedite locating 45° and 135° angular relationships (8th harmonic), which also proved themselves to be more dynamic and productive than the "soft aspects" of other astrological traditions.

1 ）快速容易的看到角状角度

2 ）增加行星间的相位 4 倍，这样行星的位置可以非常准确呈现在眼前。

3 ）容易的查看 45 度 135 度这些一样被证明比那些传统的占星学家称为“软相位”更能改变事情发展的角状相位（ 8 倍相位）

To do this, the 360° circle was cut into 4 sections, and then each section was aligned so that each began with either 0° or a multiple of 90°.   The following chart shows the correspondences:

为了做这个， 360 度星盘被割成 4 个区域，在下表中每个区域都被排成一行，每行都是由 0 度或者 90 度的倍数开始

Note that when arriving at 90° and any of its multiples, the scale starts again at the beginning.

Now, note also, that in dividing the 12 signs of the zodiac by 4, we end up with sections consisting of 3 signs, and 3 × 30° = 90°.

Thus the first round on the 90° dial consists of 0° Aries through 29°59' Gemini (i.e. 0° to 89°59')

The second round on the 90° dial consists of 0° Cancer through 29°59' Virgo (i.e. 90° to 179°59')

The third round on the 90° dial consists of 0° Libra through 29°59' Sagittarius (i.e. 180° to 269°59')

And the fourth round on the 90° dial consists of 0° Capricorn through 29°59' Pisces (i.e. 270° to 359°59').

请注意当达到 90 度或者 90 度的倍数，圆圈就重新回到开始点

还要注意，把 12 星座分成 4 部分，圆圈连续的三个星座以后结束，因为 3 × 30 度 = 90 度

90dial 盘的第一个圈由 0 度白羊到 29 度 59 分双子组成

90dial 盘的第二个圈由 0 度巨蟹到 29 度 59 分处女组成

90dial 盘的第三个圈由 0 度天秤到 29 度 59 分射手组成

90dial 盘的第四个圈由 0 度摩羯到 29 度 59 分双鱼组成

This can be summarized in other words -- each round of the 90° begins with 0° of a cardinal sign (Aries starting at 0°, Cancer at 90°, Libra at 180°, and Capricorn at 270°).

Prior to the time when astrologers had computers to draw 90° charts automatically, Hamburg , Cosmobiology, and Uranian astrologers plotted the planets and points around the chart by following the above considerations.  With the computers we have today, such calculation is no longer necessary; yet we still need to understand the underlying principles.

At this point, we have a basic summary of how the 90° dial works, and if it is not clear to you at this point, you should return to the beginning of this article, and study the comments while referring to the linear graph above, which enumerates the 4 rounds of the 90° dial, totaling 360° in the traditional zodiac.

可以被总结为－每圈代表的 90 度区域都是由本位星座开始（白羊 巨蟹 天秤 摩羯）

以前的占星学家在绘制 90dial 盘的时候，都要对行星与点的位置做相当多的考虑，现在有了计算机，一切都不同了：）我们可以通过计算机轻松的完成 90dial 盘的绘制，我们需要了解的只是基本的定理。

在这一节里面我们对 90dial 盘做了一个简单的概要，如果这一节你看不懂，就该回到文章的开头，讲图表的部分，那里列举了 4 圈的 90dial 盘。
