D According to the new development in the defferential geometric nonlinear control theory and its applications in power systems, a control strategy combined the MTDC modulation and fast steaming valving control is presented. And numerical simulation is adopted to test the usefulness of this control strategy to the transient power systems.

根据微分几何非线性控制理论的新发展和它在电力系统中的应用成果，本文推导了多机交流/多端直流系统的快关汽门与直流调制联合控制的控制规律，并用数字仿真验证了这种控制规律在电力系统暂态过程中的作用。

In addition, the HC and CO emissions are much lower than the emissions of HCCI and the indicated thermal efficiency of HCCI/DI is higher than the prototype diesel engine.Furthermore, without spark ignition and hot EGR, the HCCI/DI combustion of in-cylinder directly injected iso-octane is achieved with the induction of thermal and chemical active atmosphere generated by the HCCI combustion of port injected n-heptane.

通过对燃料理化特性、预混合率和缸内直喷时刻这三个影响因素的优化，实现了对HCCI/DI燃烧相位、放热分布和形态的调制，使发动机的负荷拓展到全负荷，在全负荷范围内NOx排放低于40×10-6排放水平，HC和CO排放显著低于HCCI燃烧，同时发动机指示热效率η_i高于原机柴油直喷的水平。

Connected to this PC are one or more fax modems or fax cards.

This modem has been known to go into stand-by mode automatically when acquired for the first time.

这调制解调器一直被称为进入待机模式时自动获得的第一次。

When this modem is in stand-by mode, the Internet/Power light will be off.

当此调制解调器是在待机模式，互联网/电源轻将关闭。

The relationships between the retransmitted noise and system parameters are analysed for three cases, i.e.

在解调型应答机中，解调的基带信号和伴随的噪声一起再调制和转发。

De la Mancha has released unstable , a VST effect plug-in for Windows that likes to mess around with your audio pitch, with 3 subtle pitch modulation modes to simulate the unpredictable but lovable pitch instability of an old tape machine or analogue equipment.

德-拉曼恰发布了不稳定的，一个的V ST效果插件在为窗口，喜欢乱七八糟靠近你的音频足球场， 3个微妙的沥青调制模式模拟难以预测，但可爱的间距不稳定的一个老磁带机或模拟设备。

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。
