The HT-6M Tokamak can be operated stably in the super low density ( SLD ) region with a : f. ew over-hot electrons by some specific methods. 通过一些特殊方法,HT-6M托卡马克可以稳定运行在只带少量过热电子的超低密度(SLD)(SLD)区域。
SF 6 gas would liquefy partly at super low temperature, so the density of SF 6 in a circuit breaker would decrease, and so did the interrupting ability and insulation level of the circuit breaker. 由于SF6气体在超低温下产生部分液化,使得断路器内的SF6气体密度下降,降低了断路器的开断能力和绝缘水平;
Because SF6 gas produces part of liquidation under super low temperature, SF6 gas density decrease inside SF6 breaker, reduce switch and insulate level of SF6 breaker, which can t guarantee SF6 breaker reliable operation. 由于SF6(六氟化硫)气体在超低温条件下产生部分液化,使得SF6断路器内的SF6气体密度下降,降低了SF6断路器的开关能力和绝缘水平,无法保证高压SF6断路器的可靠运行;
Super water absorbent used in farmland could mix with urea and low density of potassium nitrogen fertilizers, but avoid mixing with fertilizers of high concentration and strong ionization as far as possible. 树脂在用于农田栽培时,可与尿素和低浓度的钾氮素肥料混用,尽量避免和电离性强的肥料高浓度混合使用。
With the development of electronic product, people wish to pursue super portable, low power consumption, high writing / reading speed and high density memory device. 随着电子产品的发展,人们对于超便携,超低功耗以及高密度快速存储设备的需求日益紧迫。
