The effects of the terrain and terrain gradient on the heavy rain of Xichang are studied.
研究了西昌发射场特殊地形及地形梯度对其暴雨天气的影响。
The configure of heavy-hard rainfall at high and low level which causes by cold front isn't obvious, however, the strong vorticity gradient and θse unstable stratification could be found in the low level, and the heavy-hard rainfall occurred in the warm tongue in the low level. The centers of strong local helicity at 600hPa to 500hPa are corresponding to the center of rainstorm and could offer a gist for the rainstorm forecast.
冷锋云系造成的大到暴雨高、低空的配置不明显，但低层也会出现强的正涡度梯度和θse的不稳定层结，在低层的暖舌中出现暴雨。600～500hPa的强局地螺旋度中心与暴雨中心的局地强降水相对应，对预报有一定的指示意义。

All the heavy metal ions were well separated by low pressure separation column. The gradient eluent was mixture of citric and oxalic acid, and post-column reagent was 1-(2-pyridylazo)-2-naphthol. The spectrophotometric detection wavelength was at 560 nm. The detection limits for the six ions were 0.006, 0.012, 0.005, 0.125, 0.070 and 0.020 ms/L, respectively.
选用柠檬酸－草酸混合液作为洗脱体系进行梯度洗脱，将6种金属离子完全分离，柱后采用1-（2-吡啶偶氮）－2-萘酚进行衍生反应，于波长560 nm处进行检测。6种离子的检出限分别为0.006、0.012、0.005、0.125、0.070、0.020 ms/L。
The effects of temperature gradient on the forgeability of heavy forging were analyzed.
结果表明，锻件的温度梯度对其应力应变具有重要影响，温度梯度越大，锻件中心的等效应变和静水压应力越大，压实中心缺陷的效果越好。
The inhibition of phosphoinositide signaling pathway not only obviously disturbed the generation and maintenance of the tip-localized Ca2 + gradient, but also led to a heavy accumulation of callose at the tip region of Picea wilsonii pollen tubes.
