Argiope [ / i ] has the typical circular vertical web , with some broad white zig - zag stitching forming a stabilimentum on which the spiders rests , head down 这类蛛常织圆形垂直网,在中心附近会有明显粗大的支持带,形成一个大交叉。而?休息时,姿态亦像十字一样,十分有趣。
Reducing rope drag : the pro placements should be extended using runners to straighten the rope and reduce rope drag ; remember : do not allow the rope to excessively zig - zag , this will cause severe rope drag 减少绳子的阻力:放置固定点时应该用带绳使绳直能伸直减少阻力;记得不要让绳子程之字形,那会使绳子多出很多横向拉力。
In the paper it makes focal points of the zig - zag transformer " influences on the harmonics of line side and pulse shifting control influence on the harmonic of motor side . the theoretical computation and computer simulation waveforms are presented 重点分析了变压器曲折接法和移相多重化整流对网侧谐波的影响及移相pwm控制方式对减少输出侧谐波的作用,并给出理论计算结果和计算机仿真波形。
As a result of employing multilevel phase - shifted method with zig zag connection in transformer secondary , in the primary the current harmonics their orders are lower than 6m 1 are eliminated ( m is the number of power cell each phase ) . in the inverter side because of using pulse shifting pwm control , the equivalent switch frequency of output is m times as high as one h - bridge , so the output voltage waveform of the inverter is near sine with less harmonics 对于整流电路,由于采用变压器移相多重化整流,在理论上可以实现曲折变压器一次绕组中低于6m 1次谐波电流相互抵消( m为串联单元个数) ;对于逆变电路,由于采用移相pwm控制方式,等效开关频率提高m倍,因此输出电压接近正弦波,谐波含量较小。
According to the feature of base model of tire molds and our cnc machines , choose zig - zag surface to manufacture tire top and use variable contour manufacture tread grooves , create postprocessor files for different machines , customize operation templates and generate out 5 axes coordinates nc programs , and make verifications before engraving . master models were manufactured on the 5 axes cnc machines 根据轮胎模具基模及我公司数控机床的特点,分别选用了往复式曲面铣和可变轴曲面轮廓铣两种加工方法分别加工胎面及花纹,配置了机床的后置处理程序,并定制了具有本企业特点的加工模板,生成了五坐标联动数控程序,进行了仿真检验。
