Using field plot test , the control effects of three microorganic nematicides : ipc , zk7 and 412 were tested from tobacco biological character , infection situation and economic properties 摘要為了確定3種微生物殺線蟲劑ipc , zk7 , 412對煙草根結(jié)線蟲病的防治效果,通過田間小區(qū)試驗,從對烤煙的生物學(xué)性狀、發(fā)病情況、經(jīng)濟(jì)學(xué)性狀等方面進(jìn)行了全面考察。
The other part of their paper was to evaluate the risk of heavy metal ( cadmium ) movement in the field . first , the experiment of cadmium sorption was carried out in a 15mx 15m plot at yongledian , tongxian county , in beijing and 36 different soil samples were taken from the field plot according to the 3mx3m grid size 首先,在永樂店試驗站15m 15m的試驗小區(qū)上,以3m 3m為網(wǎng)格間距取36個點的土樣,獲得每個土樣的土壤質(zhì)地,對這36個土樣在實驗室內(nèi)開展鎘的吸附實驗,研究其吸附特性,獲得吸附參數(shù)。
The content of fixed ammonium , capacity of fixing - ammonium , available fixed ammonium , kinetics of ammonium fixation and release of fixed ammonium of chief upland cultivated soils in hunan province were studied by using the method of field investigation and sampling , laboratory incubation and analyses . the seasonal change of fixed ammonium content in soil and _ its bioavailability in different growth stage of huanghuacai by use of field plot experiment 本文通過野外調(diào)查取樣、室內(nèi)培養(yǎng)試驗和分析測定,研究了湖南省主要旱耕地土壤的固定態(tài)銨含量、固銨容量、有效性固定態(tài)銨含量以及土壤對銨離子的礦物固定和土壤固定態(tài)銨釋放的動力學(xué)特性,通過田間小區(qū)試驗,研究了不同施肥結(jié)構(gòu)下土壤固定態(tài)銨在黃花菜生長期間的動態(tài)變化規(guī)律及其生物有效性。
In this article , cfd software fidap is used in simulating the velocity field and temperature field of hotel guest rooms . under the two - existing air conditioning methods , the post - processing module of fidap draws the velocity field plots and isotherm line plots under the two air conditioning methods of guest rooms 本文應(yīng)用流體力學(xué)計算軟件fidap對旅館客房在兩種現(xiàn)有空調(diào)方式下室內(nèi)空氣流動的溫度場、速度場進(jìn)行了數(shù)值模擬,繪制出了客房兩種空調(diào)方式下的室內(nèi)溫度場、速度場圖。
Based on electrical capacitance tomography ( ect ) system of 8 electrodes as the main object , this paper discusses the measuring of the oil and water two - phase flow , its structure and principle for work , and the construction of finite element model , so as to make field plotting 本文以8電極電容層析成像系統(tǒng)為對象,研究了油水兩相流的檢測問題。介紹了電容層析成像系統(tǒng)的結(jié)構(gòu)和工作原理,建立了系統(tǒng)的有限元模型,并以此為基礎(chǔ)對場域進(jìn)行剖分,采用了三角形單元剖分和四邊形單元剖分兩種剖分形式。
