查询词典 weft

Owi ng to that the main shaft speed and the beating speed of reed can not attain the norma l values at setting-on, the warp tension and the beating force of the reed can neither reach the normal level. Therefore, the relative slippage movement of the weft against the warp du ring beating will be less, while the common movement of the weft together with the wa rp will be bigger than those at normal running. As a result, the setting-on place is the n caused by the normal density not being obtainable in the woven fabrics.

织机开关车时由于主轴转速、钢筘打纬速度达不到正常数值，使经纱张力及钢筘打纬力达不到一定的正常数值，以致打纬过程中经纬纱线相对滑移量比织机正常运转时的数值小、共同移动量比正常运转时的数值大，所形成的织物达不到正常的纬密，在织物上产生横档疵点。

In ordor to weave the varied weft density fabric of which weft distribution pattern is prescribed in sections,the definition field of fabric′s weft density function is divided into continuous and discrete intervals according to the variation characteristics of weft density of fabric.

为织造出分区段设定纬密变化的疏密纬织物，根据织物的纬密变化特点，把织物纬密函数的定义域分成连续区间和离散区间；在此基础上，对于分段连续且可能存在间断点的连续区间，建立了卷取量方程；分析并确定了织物各纬卷取量的解区间，给出了卷取量的求解方法——以解区间足够小为解判据的二分法，并阐明了求解方法在间断点处的有效性；对于由离散点构成的离散区间，给出了区间端点卷取量的取值方法和区间中各纬卷取量的确定方法。

The results show that the color of the dyeing PET filament fabric is invariable with different fabric structure and different looming density of weft, but the lightness and saturation is changed to some extent, and they are both decreased with the looming weft density increasing, the variation showing negative exponent relationship.

结果表明：不同的织物组织和不同的上机纬密，着色涤纶长丝织物的色相不变，但其明度L和饱和度C均有不同程度的改变，且随着上机纬密的增加，着色涤纶加弹长丝织物的明度L和饱和度C均呈下降趋势，其变化关系表现为负指数关系。

Finally, we could get the warp and weft density of fabric density through further analysis and measurements to warp and weft images.

最后通过对提取的经、纬纱细化图像进行进一步的分析和测量，得到织物的经纬密度。

When the weft runs out, or breakage, you can run under normal circumstances automatic replenishment weft.

当纬纱用完或断头时，可以在正常运行的情况下自动补充纬纱。

In order to become more practical for design of four-link the weft beat-up mecchanism, this paper presents a new the fuzzy optimization method based on considering the fuzzy randomicity of design parameters. By use of double objective optimization method, that is, for maximal accelerate of sley sword minimizing and coefficient of speed rate of sley sword traveling maximizing, mathematics model of the fuzzy optimization design of the four-link weft beat-up mechanism is set up. Calculation and analysis of pra...

设计更好地符合客观实际的四连杆打纬机构，在充分考虑各设计参数的模糊性的基础上，根据模糊方法学的基本理论提出一种模糊优化设计方法，采用使筘座的最大加速度最小，同时使筘座的行程速比系数最大的多目标优化方法，建立了该问题的模糊优化设计的数学模型，并对实例进行了计算与分析，获得最优的综合性能。

If the sley provides a means of guiding the weft insertion device through the shed, as in the Sulzer gripper loom and some flexible rapier looms, then the sley must dwell in its most backward position during the whole of the time occupied by weft insertion.

正如苏尔寿片梭织机和某些挠性剑杆织机那样，如果筘座在梭口中能为载纬器提供一个导路，则当筘座运动到最后方位置并进行引纬的全部时间内，筘座必须处于静止状态。

The mechanism that the newly woven-in weft drives the receded weft to be beaten tight again during beating-up is analyzed. The process calculating back-side warp angles of receded wefts at tightened position is presented, and then a formula of displacement that receded weft slips from receded position to tightened position is given.

分析在被钢筘打入织口的过程中新织纬驱使回退纬纱重新打紧的机制，说明回退纬纱被重新打紧时其后侧经纱角的计算流程，进而给出了回退纬纱从回退终了位置运动到打紧位置的位移算式。

V max is the same at the period of insertion , two rapiers hand over weft at the maximum velocity , the curve of weft velocity and weft tension are formed single peak .

两剑在速度近似为最大值时进行纬纱交接，纬纱速度和纬纱张力都呈单峰型

Means the parent directory, so this command means to execute "toolchain.sh," which is in the current directory.

代表父目录，所以这个命令就是执行当前目录下的"toolchain.sh"。

Yes,In fact,I'm on our city ream.

是的。事实上我是我们市队的。
