查询词典 number field

For thermodynamic and kinetic reasons, a relatively large number of materials can not be directively synthesized by self-propagating high-temperature synthesistechnology. In addition, SHS process is generally difficult to effectively control. These limitations retard the further development of SHS technology. In this project, the imposition of an external electric field is utilized to activate self-sustaining reactions and to simultaneously control SHS process.

为了扩大自蔓延高温合成技术的合成材料范围，并实现对SHS过程的有效控制，本项目分别以反应热小和反应速率低的反应体系为对象，利用外加电场诱发了体系的自蔓延燃烧，合成了在普通SHS工艺下难以合成的材料；同时，将外加电场作为SHS技术中一个重要的工艺参数，同步实现了对SHS过程的柔性控制。

The germinative number of horsebeans and peas were raised by 44% with activated water by tourmaline. 200μl 1 X 10~6/ml mouse's H_(22) cell, 200μ 4X 10~6/ml splenic cell, 200μl 1 × 10~6/ml epidermal cell were all inhibited after the action of tourmaline. It is analyzed that the factors which effected the multiplication of the cells included direct action which are tourmaline's electric field, far-infrared, negative ions and solvent ions, and indirect effect which are small water clusters and pH value.

According to this model, the dimensionless velocity potential of the incident acoustic field,(where, F is the velocity potential, v 0 the velocity amplitude of the vibration source, k =2 p / l the wave number), can be expressed as an integral equation over the surface of the levitator emitter and reflector, and then solved by the boundary element method.

该模型将入射声场速度势 F 的无量纲形式，（ v 0是声源振动速度峰值， k =2 p / l 是波数），表达为发射端和反射端表面上的边界积分方程，并通过边界元方法求解。

It's with sadness that I report to you that Lorimer Davidson, GEICO's former Chairman, died last November, a few days after his 97th birthday. For GEICO, Davy was a business giant who moved the company up to the big leagues. For me, he was a friend, teacher and hero. I have told you of his lifelong kindnesses to me in past reports. Clearly, my life would have developed far differently had he not been a part of it. Tony, Lou Simpson and I visited Davy in August and marveled at his mental alertness -- particularly in all matters regarding GEICO. He was the company's number one supporter right up to the end, and we will forever miss him. Aviation Services Our two aviation services companies -FlightSafety International and Executive Jet Aviation -- are both runaway leaders in their field.

在这里很遗憾地向各位报告， GEICO 前董事长-Lorimer Davidson，于去年十一月去世，享年 97 岁，对于 GEICO 来说，大卫是带领公司跃上台面的企业巨人，而对我个人来说，他是我的偶像，亦师亦友，在过去年度的报告中，我不只一次的提到他对我个人的关照，很显然的要是没有他，我个人的一生可能要完全改观，Tony，Lou Simpson 与我在去年八月还曾经去拜访他，对于他当时的记忆力还佩服不已，尤其是有关 GEICO 的点点滴滴，一直以来，他就是 GEICO 公司的头号支持者，我们将会永远地怀念他。

We drawn the predicted surface maps with the Ordinary Kriging method and illustrated in the time order to provide a visible presentation of the spatio-temporal distributions. By analyzing those maps, we found that the spatial distribution of spiders in the paddy field was similar to that of macropterous SBPH and larval SBPH, and was more similar to larval SBPH, and showed an obvious pursuing phenomenon between them, while the pursuing had a close relationship with the temporal dynamics of SBPH number. But the pursuing phenomenon was complex and influenced by factors such as the weather, the environmental conditions in paddy fields, other enemies of SBPH and other foods of spiders.

用普通克立格方法作出空间分布图，在时间序列上进行比较分析，得出稻田蜘蛛与灰飞虱成若虫的空间分布均有相似性，尤其与若虫相似性更强，表现出比较明显的空间跟随现象，且空间跟随现象与灰飞虱虫量的消长有密切的关系，但是由于天气、稻田环境、灰飞虱其他天敌以及蜘蛛其他猎物的存在等因素的影响使得其空间跟随又有着相当的复杂性。

A special field equation with of Faddeev model is solved. The analytical solutions with time variable of Faddeev model are obtained by utilizing the result that the SO (3) Faddeev model is equivalent to the mesonic sector of SU (2) Skyrme model where baryon number current vanishes everywhere.
