firstly, choose cotton net surface 第一,表層要選擇棉網(wǎng)面的。
all net surfaces and datum's are to be made from hardened steel and mounted to a separate base whenever possible 所有網(wǎng)面和基準(zhǔn)要由硬化的鋼制造出來同時(shí)在可能的情況下安在一個(gè)單獨(dú)的基準(zhǔn)上。
the results show good performance between vis, irl, sun zenith and net surface radiation . the correlation coefficient is up to 0.8259 通過理論部分推導(dǎo)出的關(guān)系可以看出:地面凈輻射與太陽天頂角、地面及云面反照率等因子有關(guān)。
cotton net surface prevent part of skin suffering from wetness because it is fast to absorb wetness; funnel design is better than tubbiness design, because it is not easy to flow back 吸水快的棉網(wǎng)面可使局部皮膚不受潮濕之苦;漏斗型設(shè)計(jì)優(yōu)于桶狀設(shè)計(jì),滲入的液體不易回流。
for the northern i ndian ocean, the net surface heat flux and entrainment through the bottom of mixed layer have semiannual period, which is the major cause of semiannual variations in sst 就赤道以北印度洋而言,海面凈熱通量和混合層底的卷夾過程都有半年周期,這是sst呈現(xiàn)半年周期變化的主要原因。
