1) pest damaged area
虫道面积
2) throat area
喉道面积
1.
The technical difficulty is accurately controlling the low-pressure rotor speed through adjusting nozzle throat area.
技术难点在于通过调节喷管喉道面积,精确控制发动机低压转子转速。
2.
The results show that the ratio of the throat area decreases almost linearly when the ratio of injection pressure or injection slot width increase,but the injection temperature has little influence on the throat area.
计算结果表明:喷管相对喉道面积比随注气总压比和射流缝缝宽的增大而基本呈线性地减小,而注气总温比对喷管相对喉道面积比的影响很小;注气角度对气动喉道控制有一定的影响,当注气角度在-30°左右时,相对喉道面积比最小。
4) Flow area
流道面积
5) insect pest occurrence area
虫害发生面积
6) area of grasshopper occurrence
蝗虫发生面积
1.
Study on the model between the area of grasshopper occurrence and indexes of atmospheric circulation
新疆草原蝗虫发生面积与大气环流特征量指数模型的研究
