查询词典 water level

Based on modeling test in water tank, this paper employed three different iron blocks to model water-bearing bodies and enclosed plastic pipes or rounded wood strips to model roadways. It gave physical modeling of water-bearing bodies in the working face floor with parallel Bipole-Dipole method, made analysis on the character of electrical field and the law of apparent resistivity changing when the low resistivity abnormity bodies were placed flatly close to water level under semi-space condition and were placed flatly, vertically or aslope to the water level under whole-space condition.

The analytic results obtained from the PCT evaluations revealed that the most limiting accident was the case with a break at the Main Steamline Outside Containment. Its PCT was 1289.15 ℉, which is much below the upper temperature limit of 2200℉ set by the nuclear regulatory authority. The most limiting accident for the minimum water level measured outside the core shroud is the case with a break at the High Pressure Core Flooder Line, the minimum water level drops to 18.4 ft. For this case, even though the water level has dropped to 11.6 ft below the top of the active fuel, the reactor core was still completely covered by the two-phase water.

As the surface altitude increases, the water level and the imbedded water level decrease, and is lowest in Betula ovilifolia－Carex schmidtii－Sphagnum palustre community, which may be firstly caused by the distribution of the hummocks of Sphagnum palustre, which is powerful in holding water, and this has cushion function on the change of water level; On the other hand, it may be caused by it's position near the hill, the runoff from the hill may supply the district, so that the change extent of water level at a certain extent minishes.

随着地表相对高程的增加，水位变化幅度逐渐变小，在油桦－臌囊苔草群落中最小，这一方面可能与泥炭藓丘的分布有关，泥炭藓具有较强的饱水和持水能力，对水位的变化具有一定的缓冲作用；另一方面是由于该区靠近山地，山坡上形成的坡面径流可能对该区域有所补给，这也在一定程度上减小了水位的变化幅度。
