Therefore, the calculated results from two numerical computation codes are in good agreement with those from field theory calculation. It has been proved that the applicability of this approach to mode separation research, by contrast, the tested results of mode frequency coming from the Model 2M214 magnetron (double-ring strappings) manufactured by LG Electronic Co.

对于LG 2M214型双环隔模带磁控管，模式分隔度的分析结果与韩国LG公司生产的磁控管实测结果相比较，预测误差仅为0.6%，能够与实际测试结果很好的相符合，预测精度足够高，从而证实了本方法在磁控管谐振系统模式频率分隔特性预测方面的可用性。

From the beginning of the 1990s has so far developed more than 100 specifications of the products presses are the main bellows production lines, large-diameter PVC drainage, sewerage lines, PE large-diameter gas supply, drainage pipe production lines, plate production line, granulation production lines, Plum of the production line, PP-R pipe production lines, one-to two-pipe production lines and 240 T, 180T Profile production line, plastic extrusion machines, high-speed mixer, mixed plastics and various auxiliary units and exported to the Philippines, Vietnam, Thailand , Malaysia, Russia, Iran and other places.

从90年代初起至今共开发了100多个规格的塑机产品，主要有波纹管生产线、大口径PVC排水、排污生产线、PE大口径煤气、供、排水管材生产线、板材生产线、造粒生产线、梅花管生产线、PP-R管生产线、一模双出管材生产线及240T、180T异型材生产线、塑料挤出机、高速混合机、混合机组以及各种塑料辅机，并远销菲律宾、越南、泰国、马来西亚、俄罗斯、伊朗等地。

Since opening in 2001 until now, the scale has grown Hainan now has only one of seven from Taiwan cardboard production line, its entire production process by computer control, but also have two fully automatic four-color ink printing slotting machine, automatic double - a color ink printing, die-cutting machine 3, table machine and automatic cartonmachine and a number of other production equipment, in Hainan in the same industry in the world.

公司自2001年开业至今，规模不断壮大，现拥有海南唯一一条台湾产的七层纸板生产线，其生产工艺由电脑全程控制，同时还拥有两部全自动四色水墨印刷开槽机、自动双色水墨印刷机一台、模切机三部、表纸机及自动粘糊机等一批纸箱生产设备，在海南同行业中占领先地位。

Printing cylinder that driven by pneumatic make the skid platform back off when there is no cup and double cups, so it prevents printing ink from contaminating cup die, avoiding polluting the inside of cup and damage rollers.

正常工作时出现空杯和双杯时，印刷滚筒由气动装置使滑台后退，防止油墨沾染印刷杯模而污染杯子内部和损坏胶皮。

Firstly, based on BLOB knowledge, the method transferred 3D color space to 2D angle-mode color space and defined a set of rules of truncated cone to detect shadow BLOB and reflection BLOB. Secondly, the method removed the ghost BLOB from the moving visual BLOB by calculating permanence memory. Finally, the method used a long-time and short-time dual-background model to detect static visual object.

基于BLOB知识，将3D颜色空间变换为&夹角-模差&2D空间后，定义一套圆锥裁剪规则划分出阴影BLOB和反射BLOB；再以一种持久化记忆PM方法判别出鬼影BLOB；最后改进双背景模型检测出静止目标和运动目标。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.
