27 南极(12)
I found a place near him and waited without speaking.
我站在他旁边，我等候着，不说话。
Noon arrived, and just as on the day before, the sun didn't put in an appearance.
正午到了，跟昨天一样，太一陽一不出来。
It was sheer bad luck. Our noon sights were still lacking.
这真是没办法的事。观察又不能做。
If we couldn't obtain them tomorrow, we would finally ha一ve to give up any hope of fixing our position.
如果明天观察不能完成，那测定我们所在方位的事情，恐怕只好完全放弃了。
In essence, it was precisely March 20.
今天恰好是3月20日。
Tomorrow, the 21st, was the day of the equinox; the sun would disappear below the horizon for six months not counting refraction, and after its disappearance the long polar night would begin.
明天21日是春分，析光作用映出的一陽一光不算，太一陽一以后就要没人水平线下，有六个月不能出来，太一陽一不见，极圈的长夜时期就开始了。
Following the September equinox, the sun had emerged above the northerly horizon, rising in long spirals until December 21.
从九月中的秋分日起，它在北方天际出现，沿着长长的螺旋线上升，直到12月21日。
At that time, the summer solstice of these southernmost districts, the sun had started back down, and tomorrow it would cast its last rays.
这个时候是北冰洋地区的夏至日，它又开始下降，明天就是它射一出光线的最后一天了。
I shared my thoughts and fears with Captain Nemo.
我把自己的意见和顾虑告诉尼摩船长，他对我说。
You're right, Professor Aronnax, he told me.
您说得对，阿龙纳斯先生。
If I can't take the sun's altitude tomorrow, I won't be able to try again for another six months.
如果明天我不能测量太一陽一的高度，我就不用能在六个月之一内一再做测量了。
But precisely because sailors' luck has led me into these seas on March 21, it will be easy to get our bearings if the noonday sun does appear before our eyes.
不过也正因为我这次航行的机会，3月21日把我带到这南极海中来如果太一陽一给我们现出来，我的方位是很容易测定的。
Why easy, captain?
船长，为什么呢？
Because when the orb of day sweeps in such long spirals, it's difficult to measure its exact altitude above the horizon, and our instruments are open to committing serious errors.
因为，太一陽一沿着那么拉长的螺旋线走，想在水平线上确切测量它的高度，很是困难，仪器也容易犯严重的错误。
Then what can you do?
那么，您怎样来进行呢？
I use only my chronometer, Captain Nemo answered me.
我只是使用我的航海时计，尼摩船长回答我。
At noon tomorrow, March 21, if, after accounting for refraction, the sun's disk is cut exactly in half by the northern horizon, that will mean I'm at the South Pole.
如果明天3月21日，折光作用估计在一内一，太一陽一圈轮正好切在北方的水平线上，那我就是在南极点上了。
