While the environmental impact per unit GDP had decreased, the total environmental load increased due to the enormous development of the economy. 我國單位GDP的環(huán)境負荷略有下降，但經(jīng)濟的大規(guī)模發(fā)展造成環(huán)境總負荷上升。
Seismic patch-patch-pressure gauge with a general pressure gauges the performance of medium-Pulse at the same time, environmental impact load and vibration-resistant properties. 耐震膜片壓力表具有一般膜片壓力表的性能，同時具有抗介質(zhì)脈動、沖擊載荷和耐環(huán)境振動的特性。
Through the study we take that the environmental impact load of coal is bigger than oil, that is the environmental impact of released pollutants of coal entire life cycle process is more serious. 通過研究得出燃料煤的年環(huán)境影響負荷大于燃料油，即煤的整個生命周期過程中向環(huán)境釋放的污染物影響比較嚴重。
