阈值逻辑

Changing the threshold can change the logic operation between AND and OR.

改变阈值可以在AND和OR之间改变逻辑操作。

In order to realize the multilevel switch threshold in the voltage-mode multiple-valued logic circuits, the technique of ion implantation into the channel region of the MOSFET by controlling the impurity atoms has been applied in the previous literatures, which can not only increase the difficulty of the processing and the working procedure, but also increase the manufacturing cost.

而在电压型多值逻辑电路中为了实现多级开启阈，普遍采用控制杂质原子的离子注入到MOS管的沟道区中来实现，不仅增加了工艺和工序的难度，也增加了制造的成本。

This architecture is based on ISO/IEC 18000-6C and targeted at ultra-low power consumption. By applying methods like system-level power management, global clock gating and low voltage implementation, the total power of the design is reduced to a few microwatts.

通过采用系统级功耗管理，全局钟控，行波计数器以及低阈值低电压逻辑单元等策略，设计功耗最终控制在0.35 μm工艺下的18.6 μw，并可通过仿真在0.18 μm工艺下进一步优化到7 μw左右。

Abstracts: To sample high speed random signals without drop, a design of O-shaped high speed random signals acquisition card based on the CPLD and its realization are presented. It consists of same three sets of acquisitive circuits, which construct O-shaped structure to sample the signals without drop .And it adopts threshold judging method to determine the valid data in the process of the acquisition, abandons vast of the redundant useless data at the same time, it only sends the useful data to the host computer by the way of DMA, so it is easy to processing the data. The design is concise and reliable. The sketch map of the logic circuit and the explanation of the main parts are presented. This design has been applied in the engineering project of sampling α nuclide.

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。
