The author summarizes methods of achieving ET from wetland, for example, models of Thornthwaite, Penman Monteith, Prestley Taylor, Sanjiang Plain Swamp ,eddy correlation ,remote sensing and ...

通过总结国内外湿地蒸散量的测算方法，如Thornthwaite公式、Penman Monteith模型、Prestley Taylor模型、三江平原沼泽湿地蒸散经验模型、涡度相关法和遥感方法等，提出在湿地特定的自然条件下，经验模型法在湿地蒸散中的应用要比在其它陆地生态系统蒸散研究中的应用更为准确。

Aimming at the fuel control requirement of micro-turbojet,the automobile's electric fuel pump with adaptable improvement is chosen as fuel-feed system.The performance of fuel pump and the technical difficulty of flux control as the speed of pump doesn't be measured are analyzed.Using Philips 83C552 MCU as the main control chip,the system adopts voltage negative feedback combined current compensation instead of rotation speed negative feedback and a PWM convertor to design the flux closed loop control system.

针对微型涡喷发动机的燃油控制要求，选用汽车用电动油泵进行适应性改进作为供油执行装置，详细分析了电动油泵的特性及泵转速无法测量情况下流量控制的技术难点，并以83C552单片机为核心，采用电压负反馈加电流补偿代替转速负反馈、电机通过PWM驱动的方法设计电动油泵流量闭环控制系统。

Divergence variation of snow storm indicated that the formation of negative divergent variation in lower-layer predicted the shear convergence and the snow storm generation. Nongeostrophic vorticity and divergence of wind advection contributed to the divergence variation largely.

暴雪切变线的散度变率诊断表明，低层散度负变率带及中心的生成和发展预示着未来时期内切变线辐合区的形成和发展及暴雪天气的发生，其中非地转涡度和风速平流的散度项对散度变率的贡献较大。
