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(lái)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(guò)理論部分推導(dǎo)出的關(guān)系可以看出:地面凈輻射與太陽(yáng)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(guò)程都有半年周期,這是sst呈現(xiàn)半年周期變化的主要原因。
This product uses the handwheel contraction, the net surface smooth silk screen receives the strength to be even, may disposable stretch many net frame, the working efficiency is quick, is suitable for the high request dye printing design frawl door manufacture 本產(chǎn)品采用手輪收縮,網(wǎng)面平整絲網(wǎng)收力均勻,可以一次性繃多個(gè)網(wǎng)框,工作效率快,適用于較高要求印花圖案網(wǎng)板的制作。
The net surface solar radiation ( nssr ) as one of the most important portion of global radiation budget has a great action to solar energy absorbed by surface and then affect the surface radiation budget and atmospheric dynamical process 其中地表凈太陽(yáng)輻射的衛(wèi)星遙感是全球輻射平衡遙感中的一個(gè)重要部分,因?yàn)樗砹说乇砦盏奶?yáng)輻射能量,對(duì)地表輻射平衡和大氣動(dòng)力過(guò)程等有著重要的作用。
The results show that a warm high ridge at the middle level and transformed surface cold high over the plain provide a good background condition; a cooling process produced by net surface radiation fluxes is the trigger and strengthening mechanism for the fog event; the subsidence flow at the middle and low tropospheric levels is favorable for the setting-up and maintenance of stable stratification at the boundary layer and weak wind condition at the ground layer over the fog region; the transportation of weak warm advection at lower levels and weak lift motion at the boundary layer play a very important role to the long maintenance of the fog event; the intrusion of north wind accompanied by cold advection is a main dynamic factor of the fog dissipation 結(jié)果表明:在中高層暖性高壓脊及地面變性冷高壓穩(wěn)定維持的大尺度背景條件下,地表凈輻射引起的近地層冷卻是大霧過(guò)程的觸發(fā)和加強(qiáng)機(jī)制;中低空下沉氣流的存在有助于近地層的弱風(fēng)條件和穩(wěn)定層結(jié)的建立;低層暖平流的輸入和邊界層的淺層抬升是大霧長(zhǎng)時(shí)間持續(xù)的原因;伴隨冷空氣南下的偏北大風(fēng)是驅(qū)使大霧消散的動(dòng)力因子。
First, under the given boundary condition and reasonable simplified condition, this paper develops radiation transmitting equations in atmosphere applied in infrared waveband and visual light waveband from common equation of radiation transmitting . then, the formula between observation of satellite and net surface radiation is established according to the developed equations, from which it is found that net surface radiation is relative to sun zenith, land surface and cloud albedo, etc . at last, by using data of satellite visual light ( vis ), infrared 1 ( ir1 ), infrared 2 ( ir2 ) and water vapor ( ir3 ) channel, sun zenith and net surface radiation, a regression formula is built 本文從大氣中太陽(yáng)輻射傳輸?shù)囊话阈苑匠倘胧?,引入邊界條件及簡(jiǎn)化條件,推導(dǎo)出紅外波段和可見(jiàn)光波段的大氣輻射傳輸方程,由此建立起衛(wèi)星觀測(cè)輻射與地面凈輻射的關(guān)系,文章還就衛(wèi)星觀測(cè)到的輻射與云量、云高、云的光學(xué)厚度、云及地面反照率等之間的關(guān)系進(jìn)行了理論分析,可以幫助更好地理解云對(duì)地面凈輻射的影響。
