Considering "addition theorem of probabilities", the above idea can be expressed as follows: Assum that a beam passes through a partition with two slit and arrives a screen. The probability of the event that an indivedual particle falls on somewhere of the screen under the condition that two slit open simultaneously, is equal to the sum of two probabilities of the same event under that two slit open in turn.

考虑到"概率的加法定理"，这种看法可表成："当一个拉子束通过一个带有两条缝的隔板到达一个屏上时，在两条缝同时打开的条件下单个粒子落在屏土某处的概率，等于在两条缝轮流打开的条件下该拉子落在该处的两个概率之和。"

On the poet's choice, mainly be decided by two standards, one is the popularity and influences of works; two is the meaning of the creations development that it create for the whole colony. Owing to above two standards, the writer chooses seven writers to launch the treatise, they are Jidi Maja, Jimu Langge, Luwu Laqi, Ma Deqing, Aku Wuwu , Asu Yuer, Eni-Mushashijia. In discussing the process, the writer used the nationality and Poetics of the poem as the latent clues, emphasized to inquiry into three main roads and three main realms. On the article structure, the full text mainly is divided into two parts, one is the concrete imago analysis to each poet creations, two is upon the analytical foundation the integration of the theories, with this the treatise could be united into an organic whole. In regard to the conclusion, we educe the characteristics of the colony is deep consciousness to the nation culture, also extensive exploration and attention to poetics. The blemish is the inside emotion and sensibility is similar or duplicate and that the creation pattern is narrow. The main develop threads of the colony are upon the female clan culture the diverse poem skill investigation, its nation culture value tropism present the rising spiral type of return- leave- return again.

在研究方法上，本文以意象分析法为贯穿全文的主要方法，通过对意象的具体分析来****凉山诗群的诗歌世界；在诗人的选择上以其作品的影响力及意义为标准，选择了这一诗群的七位诗人展开论述，他们分别是吉狄马加、吉木狼格、倮伍拉且、马德清、阿库乌雾、阿苏越尔、俄尼·牧莎斯加；在论述过程上，笔者以诗歌的民族性和诗性作为前后贯穿的潜在线索，着重探讨了这一诗群创作的三个主要倾向和三个主要领域，前者详论，后者略述，具体表现在对前三位诗人的论述以诗人论的形式详细展开，探讨他们所代表的凉山诗群发展过程中的三个主要创作倾向，即民族文化的深层开掘、诗艺的实验性探索和艺术哲学的尝试性建构，对后四位诗人的论述则以主题的方式展开，探讨他们所代表的凉山诗群在爱情诗、乡土诗和文化诗三个领域的探索；在文章结构上，全文主要分为两大板块，一是对各位诗人创作的具体意象分析，二是在前文分析的基础上进行理论的整合，以此将前面散珠似的论述贯穿成一个有机整体；在结论上，我们通过整合得出：1、凉山诗人群新时期以来诗歌创作的大致发展脉络：在母族文化的基质之上的多元诗艺探索，其民族文化价值取向呈现为回归—离去—再回归的螺旋式上升形态；2、新时期彝族凉山诗人群汉语诗歌创作的特点，即民族文化意识的深层自觉，对诗性的关注和探索；3、新时期彝族凉山诗人群汉语诗歌创作的缺陷，即情感意蕴的雷同和创作格局的狭小。

Mao not only the Chinese big bourgeoisie and the capitalist class is divided into two parts, the national bourgeoisie, but again the big bourgeoisie is divided into pro-Japanese and Anglo-American faction factions; not only that the national bourgeoisie have a revolution and the two sides to compromise, and that Britain and the United States to send the big bourgeoisie is also the two sides of the anti-Japanese and anti-communist, and anti-Japanese and anti-communist and each of its two sides; and based on the distinction between the two sides of the above understanding of Mao Zedong with the various parts of the development of the bourgeoisie and the struggle against a series of joint and differentiated policy so as to achieve, consolidate and develop the anti-Japanese national united front and the second KMT-CPC cooperation, for all the final victory of the Anti-Japanese War, laid a solid theoretical foundation and basis of a policy.

毛泽东不仅把中国资产阶级分为大资产阶级和民族资产阶级两部分，而且又把大资产阶级分为亲日派和英美派两派；不仅认为民族资产阶级有革命和妥协的两面性，而且认为英美派大资产阶级也有抗日和反共的两面性，而抗日和反共又各有其两面性；基于上述区分和对两面性的认识，毛泽东制定了同各部分资产阶级又联合又斗争的一系列有区别的政策，从而为实现、巩固和发展抗日民族统一战线和第二次国共合作，为全民抗战的最后胜利，奠定了坚实的理论基础和政策基础。

My next Care was for some Ammunition and Arms; there were two very good Fowling-pieces in the great Cabbin, and two Pistols, these I secur'd first, with some Powder-horns, and a small Bag of Shot, and two old rusty Swords; I knew there were three Barrels of Powder in the Ship, but knew not where our Gunner had stow'd them, but with much search I found them, two of them dry and good, the third had taken Water, those two I got to my Raft, with the Arms, and now I thought my self pretty well freighted, and began to think how I should get to Shore with them, having neither Sail, Oar, or Rudder, and the least Cap full of Wind would have overset all my Navigation.

其次，我必须搞到枪枝和弹药。大舱里原来存放着两支很好的鸟枪和两支手枪，我都拿了来，又拿了几只装火药的角筒，一小包子弹和两把生锈的旧刀。我知道船上还有三桶火药，只是不知道炮手们把它们放在什么地方了。我找了半天，终于找到了。有两桶仍干燥可用，另一桶已浸水了。我就把两桶干燥的火药连同枪支一起放到木排上。这时我发现木排上装的东西已不少了，就开始动脑筋如何运上岸，因为一没帆、二没桨、三没舵，只要有点风，就会把木排打翻在海里。

By adjusting the positions and angles of the two DVD optical pick-up heads, the relative distance of the two laser spots can be equivalent to one quarter of the grating pitch. When the grating moves, the surface profile of the grating can be measure directly, in order to obtain the two quadrature sinusoidal signals. Then by counting the zero crossing of these two quadrature sinusoidal signals and calculating the interpolation value of these two quadrature sinusoidal signals, the moving direction and moving displacement value of the grating can be obtained.

采用两个光学读取头，且两个光学读取头共用同一分光镜与同一聚焦物镜，於搭配光路的设计，可使两个光学读取头之光束打入同一聚焦物镜，藉由调整两个DVD光学读取头的位置与角度，使聚焦物镜聚焦的两相近聚焦光点的距离相等於四分之ㄧ光栅尺间距，当光栅尺移动时，可直接量测光栅尺的表面轮廓变化，以获得一组正交的弦波讯号，继而利用讯号四分割与细分割处理，计算出光栅尺之移动方向与移动量。
