| 1. | Trapping effects of populus canadensis bundles on helicoverpa armigera in field 加拿大杨枝把田间诱蛾效果观察 |
| 2. | A new foam diversion model considering trapping effect in matrix acidizing 基质酸化中考虑圈闭效应的泡沫分流模型 |
| 3. | Extreme could or hot weather has a trapping effect and tends to cause a build - up of pollutants 多云的阴天或者炎热的天气里,污染物易于积聚。 |
| 4. | In the second chapter , on the basis of the work of smerzi et al , we discuss the 7r - phase oscillations and the macroscopic quantum self - trapping effects under the symmetric time - independent well 基于smerzi等人的工作,在第二章主要讨论了对称不含时势阱情况下系统的位相振荡和宏观量子自囚。 |
| 5. | When the polarization direction of the incoherent field and the amplitude and phase of the applied coherent fields satisfy certain conditions , the coherent trapping effect is maintained 非相干泵浦产生的量子干涉在一定条件下可以保护相干布居捕获。我们获得产生相干捕获的条件,找到由两基态构成的暗态和亮态。 |
| 6. | To analysis the principle of degradation and destruction , a reasonable relationship between the electrostatic potential and 1 - v characteristic parameters is raised ; a computation model for electron trap effect is originally proposed , which leads to a conception of critical trap electron density 本文首次建立了晶界势垒高度与伏安特性参数之间的关系,提出了陷阱效应在冲击老化过程的作用模型,引入了“临界陷阱电荷密度”的概念。 |
