The effect of water content on diffusion of pesticides under very dry conditions has been investigated . 人们曾经研究了在十分干燥的情况下水分含量对农药扩散的影响。
With sufficient forward bias, the diffusion capacitance can easily exceed the space charge region capacitance . 当正向偏压足够高时,扩散电容很容易超过空间电荷压电容。
The effect of diffusion of soil removal was demonstrated with polyester film and radio-tagged stearic acid . 污垢去除中的扩散效应,是用聚酯薄膜和放射性标志的硬脂酸来进行测试的。
When diffusion controls, the moisture fraction decreases in a complex but close to exponential manner with time . 当扩散控制时,湿含量遵循着复杂的但接近于指数关系的形式而随时间降低。
The lower boundary of the region above which molecular diffusion dominates is 120 km altitude and is known as the turbopause . 分子扩散占主导地位的区域下界约在120公里处称为湍流层顶。
The vascular changes interfere with diffusion of nutrients from plasma into adjacent perivascular tissue and cells . 这些血管变化干扰了营养物质从血浆中向血管周围邻接的组织和细胞扩散。
The process of diffusion would often be very slow, depending on climatal and geographical changes, on strange accidents . 分散的过程很缓慢,这取决于气候与地理的变迁,取决于意外的偶发事件。
The diffusion of a particle or molecule with respect to a stationary frame of reference was discussed in the preceding chapter . 一个粒子或者分子相对于稳定参考系统的扩散已在前一章中作过讨论。
Both ion diffusion and transport of ions to the root surface by mass flow appear to be dependent on soil moisture content . 离子扩散和通过质体流动把离子运送到根表面,看来似乎都取决于土壤的含水量。
There is a good chance that this outward diffusion of neutrinos and antineutrinos plays a crucial role in the supernova explosion . 中微子和反中微子的这种向外的散射很可能在超新星爆发中起着关键的作用。
