研究表明:電解液的配製過程中,氯化釕濃度、溶液ph值、陳化時間、溶液溫度對電鍍效果均有影響,其中溶液ph值是最主要的影響因素;在儀器的使用條件探索中,理論結合實驗確定了本電鍍液體系循環伏安電勢窗的理想范圍,並發現循環伏安掃描速度和掃描周期對電鍍結果也有較大影響;混合氧化物的共沉澱是目前研究熱點,在此選用與釕同一族的銥作為共沉澱元素,銥的加入會阻礙氧化物的沉積速度,銥的比例超過50 %會使沉積作用停止,但是二元氧化物的協同作用使沉積的活性物質比容量大大提高;一定溫度下退火后處理作用會使水合釕化物轉變成混合價態的氧化釕,從而提高活性物質的穩定性。The above analysis showed that this heavy rainfall event took on obvious meso - scale characters and was the combination of the three flows, so we can deduce : ( 1 ) surface southeasterly wind and topography may play the main role in this event ; ( 2 ) the easterly cold air rushing into the southern shaanxi province in the lower troposphere was strongly relative to the form of surface cold - front type of occlusion ; ( 3 ) there were two reasons for the secondary circulation ' s strengthen in the evening, one was the effect of a mountain - valley wind and the other may be latent heat leading to ascending motion ; ( 4 ) the shape of potential instability stratification corresponded well with the development of the warm - moisture advection ; and ( 5 ) the vapor providing essential thermodynamics was transported by a southwesterly low - level jet from the bay of bengal and the south china sea. furthermore, with the effect of terrain, the southern shaanxi province became the center of this extremely heavy rain process
中尺度結構分析表明,本次暴雨具有明顯的中尺度特徵,是由三支氣流共同作用的結果,分析發現( 1 )地面東南風和地形在這次大暴雨過程起主要作用; ( 2 )東路冷空氣主要是通過中低層侵入陜南地區的,並與地面冷式錮囚鋒的形成密不可分; ( 3 )夜博士論文:中尺度地形對陜南暴雨的影響研究間垂直次級環流發展加強可能有兩個原因,一個是由於地形山谷風的作用,另一個是降水的潛熱釋放激發了上升運動: ( 4 )位勢不穩定層結的形成與低層暖濕平流的發展有很好的對應關系; ( 5 )本次暴雨的水汽主要靠偏南風急流將孟加拉灣和中國南海的水汽輸送至西北地區東部,為暴雨的發生提供了必要熱力條件。The maize and neorgelia cawlinae meyendor ffii were treated with uv - b radiation with the intensities of 0uw. cm - 2 ( ck ), 10uw. cm - 2 ( r1 ) and 15uw. cm - 2 ( r2 ), the duration of uv - b treatment were ten hours per day ( from am8 : 00 to pm18 : 00 ). the effect of uv - b radiation on the photosynthesis was studied, and the results showed as follows : ( l ) the effects of uv - b radiation on photosynthesis of maize and neorgelia cawlinae meyendor ffii the results of the experiment show that the photosynthesis of maize seedlings was restrained because of the decrease of chlorophyll contents activity of hill reaction stamotal conductance activity of pepcase and atp content caused by increased uv - b radiation, and it was more restrained under higher uv - b radiation. though the activities of rubpcase and pepcase were decreased, the chlorophyll contents activity of hill reaction stamotal conductance of mature maize were not affected, therefore the photosynthesis of grown - up plant was not affected
Cm ~ ( - 2 ) ( r2組)的uv - b輻射,每天處理10小時( 8 : 00 ? 18 : 00 ) ,直至玉米成熟,以自然光照為對照( ck組) ,對增強uv - b輻射條件下玉米和紅彩鳳梨光合作用的響應作了深入的研究和探討,結果如下: ( 1 ) uv - b輻射對玉米和紅彩鳳梨光合作用的影響研究結果表明,因增強uv - b輻射降低了玉米幼苗葉片的葉綠素含量、 hill反應活力、氣孔導度、 pepcase活性和atp含量,從而影響了玉米幼苗的光合作用,使其光合速率下降,且隨uv - b輻射強度的增加其影響程度加大;而玉米成株在增強uv - b輻射環境下其葉綠素含量、 hill反應活力、氣孔導度等未受影響,雖然其rubpcase活性和pepcase活性有所下降,但總體上其光合作用受到的影響不大。分享友人
