发送端采用脉时调制方式，将二进制数字信号调制成某一频率的脉冲序列，并驱动红外发射管以光脉冲的形式发送出去；接收端将接收到的光脉转换成电信号，再经过放大、滤波等处理后送给解调电路进行解调，还原为二进制数字信号后输出。

Assembling a quilt requires some thinking ahead. First, a quilter selects a pattern and then cuts pieces of fabric and sews them together to form an overall design. Usually, smaller pieces of material are sewn together into larger blocks or squares, and then those blocks are stitched together to make the top layer of the quilt. Once the top layer is as big as the quilter wants, it's joined together with the padding and the bottom layer using a frame.

缝制拼布需要事前规划；首先，缝纫者会挑选希望的图案花色，然后将织物剪成一片片，再将它们缝在一起，形成一个完整的设计样式；通常，较为小片的布料会被缝制成一大块或正方型，接著，再将这些方块缝成一大片，当做成品的表布；一旦表布的尺寸达到缝纫者想要的大小后，就可以使用框架将表布、填料及底布结合成一体。

Firstly, the digital watermarking was transformed randomly, and then encrypted by chaos. The encrypted watermarking was transformed to one-dimensional row vector, and the pixel value was sorted. The coefficient of primitive image of stationary wavelet transformation was expanded to one-dimensional row vector, too, and then the sorted watermarking was embedded to the sorted low frequency and turned to two dimensions.

将上好的面粉用盐水加用灰草烧成的灰碱和好，反复揉搓后，拼成薄薄的面皮，撒一层豆粉，折成三指宽的一叠，用刀细细切过，轻轻抖散，松松地拧成一绞，摆放整齐。

Water is very humble, it is always down, down, may it flow into rivers and lakes; Hill is very humble, it is always silent, silent, be it in the stands as a silent picture; the spring is very humble, It is always fierce winter to hotels specifically catering, be it the warmth of life; autumn is very humble, it is always in the quiet after the noisy arrival of summer, it can be brought about gains and maintain a humble heart, Life there is a dignity and value can not be conveyed in words.

水很谦卑，它总是向下、向下，可它却流成了江河湖海；山很谦卑，它总是沉默、沉默，可它却在无言中耸立成一座风景；春很谦卑，它总是在凌厉的冬后悄然而至，可它却温暖了生命；秋很谦卑，它总是在喧闹的夏后静静到来，可它却带来了收获，保持一颗谦卑的心，生命就有了一种无法言传的尊严和价值。

Calcium carbonate and soluble glass and so on were confected as alkaline antifouling agent. The Infrared Spectrometry results showed that 2275-2250 cm~(-1) diagnostic absorb wave crest in part A and 3390-3200 cm~(-1) in part B and 1730 cm~(-1) in coating film strongly proved polymers reacted just as the reacting mechanism, that means polysiloxane which offer low-surface-energy property linked Polyurethane system by —OH groups reacting with —NCO groups. Relative molar mass of part A and part B was determined by Gel Permeation Chromatography and the results were appropriate. Surface-energy was determined and results were between 33.6-47.17 mN/m and it increased when alkaline antifouling agent was put into the coating. Alkaline antifouling agent was releasing steadily when the coating film was dipped in seawater. As time gone, the pH value of seawater was increasing. Solubility parameter and results showed that there was no corrasive phenomenon between the polyethylene strand and the coating.

Analysis is conducted on model checking for three valued logic formulae of modal transition system using existing model checking techniques. We reduce the three valued logic model checking problem for modal transition system to the two valued model checking problem under Kripke structure. This reduction is linear in the number of states, size of transition relations, and number of atomic propositional formulae in the new formed model compared with those in the original model. It does not increase the comple...
