In the end,the low-pass filter was designed and simulated with Pspice.

最后对滤波器进行了初步设计，最后使用Pspice软件对滤波器进行了仿真。

Sean introduces you to the principles of creating hi-res poly models by modeling the head of an intricately detailed 4-eyed creature, based on a maquette.

在这个教学中，Sean逐步建起一个杂乱的，带有四眼的生物头部，使用一组初步设计的模型草图的图片（可参阅Neville Page的手工雕塑的教学），Sean向你介绍建立高分辨率多边形模型的原理。

MIRV missile separation rule was built. Preliminary optimum design and optimize separation sequence were carried out. According to target attacking sequence and separation sequence which are preliminarily certain, the optimum separation sequence was determined by building compatibility rule of target attacking sequence and MIRV missile separation sequence.

结合多弹头导弹弹头特性建立了子弹头的分导原则，对子弹头的分导顺序进行了初步设计与优化根据确定的目标打击顺序和优化的子弹头分导顺序，建立目标打去顺序与子弹头分导顺序的一致性原则来确定子弹头的最佳分导顺序。

Some parameters of several components in the initial design, such as collimators and monochromator, were modified after optimization.

通过模拟优化研究，对初步设计方案中的单色器和准直器参数作了必要的调整。

Numerical results show that this method is suitable for the preliminary design of formation flying.

仿真结果表明，此方法适用于编队飞行的初步设计。

In January, 2006 ~ in July practises in the China Petroleum and Chemical Corporation group company Mt. yanshan petrification limited liability company, during joined Mt. yanshan to petrify the MTO test installation the preliminary design work; Knows very well chemical flow and so on enterprise equipment, facility, pipeline management and the examination method. 2006.7 is hired officially in the Mt.

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。
