The manner in which the seam ends are cut depends on the method of manufacture, for example, if the shoulder seam s are sewn and pressed open, it is important the seam ends are the same shape as the armhole and neckline.

缝端的裁剪方法根据制作的要求而定。例如，肩缝缝好后要进行分开烫，肩缝的缝份与袖窿和领曲线一致，这是很重要的。

It is a new topic that rule of ground movement in deep dip angle coal seam mining, the coal seam angle is one of important factor of deciding the rule of ground movement , the overlying rock of steep coal seam mining have different homogeneousness in horizontal orientation.

倾斜煤层是指煤层倾角在15°—55°之间的煤层，倾斜煤层开采地表沉陷移动规律是地表沉陷研究领域中的一个重要组成部分，煤系地层倾角是决定上覆岩层的移动和破坏形式及地表移动与变形程度的重要因素之一。

The methods of adaptive median filter, variance ratio of interclass and intraclass segmentation, and mathematical morphology were used to decrease the noise of original welded seam image, to extract welded seam region, and to carry on high frequency enhancement transformation for the interior of extracted welded seam with frequency range sharpening.

利用自适应中值滤波方法和类间、类内方差比分割法及数学形态学方法对原始焊缝图像进行降噪和提取焊缝区域，并对提取的焊缝内部进行频域锐化的高频加强变换。

Simulation results indicated that the adaptive median filtering effectively removes noise, and maintain the details of welded seam and defection edge; the variance ratio of interclass and intraclass segmentation could accurately distinguished between the welded seam metal and the base metal together with mathematical morphology method; high frequency enhancement extrudes the welded seam center, consequently defects would be detected.

仿真结果表明自适应中值滤波能够有效去除噪声，并保持焊缝和缺陷的边缘细节；类间、类内方差比分割方法与数学形态学方法并用，能准确的将图像分割为焊缝与母材区域；高频加强变换能够使焊缝中心部位突显出来，从而实现缺陷的检测。

The steeply dipping seam refers to the coal seam that the declining angle is between 35°and 55°. It is an important part in strip mining research to decide the reasonable width ofsteeply dipping seam strip coal pillar under village.

大倾角煤层是指煤层倾角在35°～55°之间的煤层，村庄下大倾角煤层条带开采煤柱尺寸的合理留设问题是条带开采研究领域中的一个重要组成部分。

After the seam has been stitched, trimmed, and graded, turn the facing to the inside and edge stitched, trimmed, and graded, turn the facing to the inside and edge stitch along the seam line, attaching the facing to seam allowance.

缉缝缝线并发层修剪后，把挂面翻到衣服里面，沿着缝线用倒钩针把挂面敷在衣片的缝份上。

It was shown that coal seam floor failure depth of working face 2121 was 32.5 to 5 m, approximately three times as deep as that of shallow working face(in genera l,9.15 to 12.0 m). Coal seam floor failure depth increased with mining depth. Potential risk of water inrush through coal seam floor of working face 2121 is much higher for deep mining than for shallow mining.

试验结果表明：该工作面底板破坏深度为32.5~35 m，比300 m采深以内的工作面实测深度(9.15~ 12.0 m)增加2倍以上，说明随着开采深度的增加，煤层底板采动破坏深度呈明显增大的趋势，因此，在水压和破坏深度二者同时增加的条件下，2121工作面深部煤层开采的突水危险性远远大于浅部煤层。

At last, the rational mining method is determined as the staggered layout of coalface in the upper and the lower coal seam, with the upper coal seam is mined first and the lower coal seam is mined with the whole height.

计算机数值模拟与现场实践表明，7煤与9煤的工作面成交错布置方式，先采7煤后采9煤，一次采全高，最有利于9煤工作面的顶煤冒放，保证9煤综放开采的成功。

And it is concluded that the No.4-2coal seam is a mid-reserve and low-permeable seam, with surrounding rocks having low enclosed system and high permeability. And the coal seam's gas content is low, while its quantity in the roof-sandstone which is the main source of coalface's gas emission is high . The quantitative index used to analyze gas content and gas emission amount are pointed out systematically. And gray association analysis method is adopted to search the main factors affecting coal-bed content and gas emission amount.

系统提出了分析影响煤层瓦斯含量与采面瓦斯涌出量大小的量化因素指标，并将灰色关联分析原理引入煤层瓦斯含量与瓦斯涌出量主控因素的研究中，筛选出了煤层顶板含油指数，顶板砂泥岩比、4-2号煤层顶板以上煤系厚度3个因素指标为影响4-2号煤层瓦斯含量的主控地质因素；煤层埋藏深度，煤层瓦斯含量，煤层顶板含油气砂岩厚度，煤层顶板含油强度及工作面回采进度5个因素为影响综采面瓦斯涌出量的主控因素。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
