1) area of gradually varied seepage flow
渗流缓变区
1.
The conclusion was gotten that the standpipe piezometer was suitable in the area of gradually varied seepage flow instead of rapidly var-ied seepage flow area.
认为测压管适用于"渗流缓变区"的渗流压力监测,而不适用于"渗流急变区"的监测,同时明确了渗流"综合滞后时间"等相关问题,认为在土石坝"渗流急变区",尤其是渗透系数小、水位变幅大的"渗流急变区"的渗流压力监测应采用渗压计,不宜采用测压管。
2) area of rapidly varied seepage flow
渗流急变区
4) area of slack water
缓流区
5) slowly varying current
缓变电流
1.
On the particularity of the gathering of feeble and slowly varying current,this thesis discusses the fundamentals of chopper-stabilized minutely and designs a high-speed,high-precision,high-resolution ratio and low-noise universal feeble and slowly varying current digital gathering system using TLC2652 amplifier,and ADS8411B with parallel interface and controlled by CPLD.
本系统广泛适用于仪器仪表、测控系统及工业现场控制等对微弱缓变电流进行中、高速率采集而且分辨率要求较高的场合。
6) vadose zone
渗流区
1.
Numerical simulation of contaminant transport in vadose zone during rainfall and evaporation;
降雨蒸发条件下渗流区污染物迁移的数值模拟
2.
The simulation of removal of toluene by bioventing in the vadose zone;
甲苯在渗流区的生物通风去除模拟
补充资料：缓变pn结（gradedp-njunction）
缓变pn结（gradedp-njunction）
从p区到n区掺杂浓度逐渐改变的pn结，如用固态扩散工艺制造的pn结。大多数缓变pn结数学上可作为线性缓变结处理。通常由扩散工艺制备的pn结为缓变pn结，但在浅扩散结或高反偏时它更接近于单边突变pn结。
