势垒

The field emission of diamond film involves the electrons travel from the negative end of the power supply, through the various interfacial contacts, through the bulk of the film itself, to the film surface,then tunnel through the potential barrier ,propagate through the vacuum gap, before finally reaching the anode.

金刚石膜场致发射过程是电子从导电基底开始，经基底/金刚石界面、金刚石薄膜体内传输到表面，然后穿过表面势垒进入真空、经真空电场加速到达阳极的一个复杂过程。

Through comparison with the classical dielectric polarization theory, we have demonstrated that this capacitance response is essentially a consequence of the non-local property of the wave-functions and the quantum confinement supplied by the potential barriers, so it is referred to as"the QCSE-related quantum capacitance".

与经典介质极化理论的比较表明该电容响应与载流子波函数的扩展性和量子阱势垒的量子限制作用是密切相关的，故称之为"QCSE量子电容"。

It is found that AIN passivation layers can still increase the density of two-dimensional electron gas despite the additional responses.

表面钝化被认为可以有效地降低势垒层Al Ga 一N表面态密度，一直以来被广泛用于提高HEMT器件的性能。

The three molecular decomposition reactions studied here are all concerted, and the radical reactions all endothermal and barrierless.

本文所研究的分子解离反应全部为协同过程，而自由基解离过程都是无势垒的吸热过程。

The outcome of free energy barrier is of the most significance.

对自由能势垒的研究是最有意义的。

However, an energy barrier is shown.

而发现了能量势垒的存在。

No free energy barrier is found in our calculation.

发现在整个穿出管道的过程中没有自由能势垒的存在。

That there is a quantitative relationship between the height of the energy barrier opposing rotation and the rate of rotation will be discussed later.

这之间存在的能源，反对旋转势垒高度和轮换率的定量关系，将在后面讨论。

The energy barrier of the first step is much ligher than that of second one.

第一步反应势垒较大。

Finally,a summary of the materials used for the ferromagnetic ...

文章最后总结了用于MTJs的各种铁磁层和绝缘势垒层材料，并对TMR材料今后的研究和开发作了展望。

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。
