The author made an analysis of the ratchet gearing used let-off mechanism in the K251 type loom and of the effect to loomage, and came to the conclusion that is: 1. The long length of the loom cause bigger LO, which reduce weaving defects caused by let-off error. 2. At the same status of the loom, the possibility of appearing weaving defects is relative to the characteristic of the loomage, namely, if the stiffness coefficient of the loomage and organzine has lesser difference, the possibility of appearing weaving defects will be lesser, contrarily will bebiggish. 3. The displacement error AL affects the value of the weavingdefects directly, besides wind error, it is a effective method to reduce let-off error.

通过对K251丝织机棘轮送经机构及其对织物影响的分析，得出以下结论：1、丝织机的长机身使Lo较大，有效地降低了由送经误差造成档疵的可能。2、在织机状况相同的情况下，档疵出现的可能性与织物的特性有关，即织物与经丝的刚性系数相差较小的，档疵出现的可能较小，反之较大。3、织口位移误差△L，对档疵有着直接的关系，除了卷取误差，减少送经误差是减少档疵出现的有效的方法。

A measuring system which mainly consists of a high precision motorized translation stage of one dimension, POINT GREY Flea2-14S3 CCD camera and LED light source was designed and constructed. Based on a detailed analysis for experiment results, the periodic changing law of system error of LED facula centroid location in this measuring system was found. The results indicate that based on Flea2-14S3 CCD camera, the random error of facula centroid location is about 0.018 pixels, the system error is about 0.06 pixels, and the total error is about 0.063 pixels (1/15 pixels).

Custom Error Pages 自定义错误页 The first use of the .htaccess file which I will cover is custom error pages. These will allow you to have your own, personal error pages (for example when a file is not found) instead of using your host's error pages or having no page.

我想介绍的。htaccess第一个应用是自定义错误页面，这使得你可以拥有自己的、个性化的错误页面，而不是你的服务商提供的错误页或没有任何页面。

However, it is impossible to foresee the decoder state within the round-trip delay time. Consequently, to prevent such possible error effects, we further enhance SBET by ROPE. The encoder will recursively keep estimating the expected decoder pixel distortion. The distortion of frame reconstruction at the decoding side includes the quantization error, propagation error, and concealment error.

然而，在往复延迟时间内的情况则是无法预知的，因此为防范可能的错误蔓延，我们提出将递回式最佳像素预估法与其进一步结合应用，让编码端用递回的方式计算出解码端像素失真量的期望值，此失真量会包含量化失真、错误蔓延的错误和错误隐藏所带来的错误。

The comparison error rate of LSD and Duncan is equal toα, but their experimental error rate is large toα. The comparison error rate of SNK, Scheffe, Bonferroni, Sidak are smeller toα, as well as experimental error rate. The power of test of SNK, Scheffe, Bonferroni, Sidak are smeller to LSD and Duncans.
