Twenty years later scientists found that a virus that causes the veterinary disorder newcastle disease shows a preference for infecting tumor cells and began to try to enhance that tendency by growing the viruses for generations in human cancer cells in laboratory culture dishes 20年后,科學家發現引起新城雞瘟的病毒,特別偏愛感染癌細胞,因此他們在實驗室里的人類癌細胞株中培養此種病毒,試圖加強這種傾向。
In the paper , a series of the field investigation , laboratory culture and pot experiments were conducted , to study microbial eco - characteristic and restoration in relation to soil - plant system of red soils reclaimed - mine . the main results were summarized as below : 1 . soil microbes eco - characteristic in lipu copper mining reclaimed soil - endurance plant system were studied comparatively , zhe jiang province 本論文采用野外礦區調查、實驗室培養和溫室盆栽試驗相結合的方法,對我國南方紅壤礦區土壤的微生物生態特征及其穩定性恢復進行了研究,以期為礦區重金屬污染及退化土壤微生物生態系統的生物修復及土壤復墾工程提供理論技術依據。
Laboratory culture experiment with the same treatments as pot experiment but without plant was carried out synchronously under constant temperature ( 25 ? ? ) and 20 % soil moisture . to study the influence of inhibitors on the dynamic process of transformation and variation of availability of cd in soil , laboratory cultured soil was sampled in certain interval during the 128 - day cultured period for the analysis of cd availability and speciation . in adsorption - desorption experiment , the tested soil had fistly been cultured under constant temperature ( 25 1 ) and 20 % soil moisture for two months after the treatment according to the designed plan , then isothermal adsorption - desorption experiment was proceeded when the reaction between inhibitor and soil tended to be stable 石灰施用量對植株吸收鍋有顯著影響,植株各部位鍋含量k )與石灰添加量… , )的關系可以很好地用方程y叫( ax斗bx化)描述,石灰對植株鍋累積的調控存在一個最佳抑制效應劑量,低于或高于這一劑量均不能達到最佳抑制效果,但對于不同植株部位和不同污染水平,最佳抑制效應劑量不同;低用量下,單位石灰添加量對植株吸收鍋的抑制作用比高用量時大,因此若綜合考慮調控劑的施用成本及其對生物量的影響效應,則在本試驗條件下以施用石灰0
With the purpose of better understanding some weak links in this subject , we comprehensively and systematically compared the effects of some typical inhibitors and their different combined ways in inhibiting cd bioavailability in purple soil , further studied the laws and affecting factors of cd ' s transfer and transformation in soil - plant system , revealed the mechanisms inhibitors function , and explored the practicable inhibitor prescriptions and their usage . the results are expected to provide reliable techniques for controlling cd pollution of agricultural soils in chongqing and it is also significant to ameliorate soils polluted by other kinds of heavy metals . comprehensive methods including pot experiment , laboratory culture experiment , kinetic and thermodynamic adsorption - desorption experiment were adopted in this study , and the acidified purple soil was chosen to test , considering that cd is highly active in this soil 本研究針對重慶市農業土壤的污染狀況,選取鎘活性較高的酸化紫色土為供試土壤,采用盆栽試驗、培養試驗、化學熱力學與動力學吸附試驗相結合的方法,系統研究和比較多種調控劑及其不同組合方式對鎘生物活性的效應,并揭示鎘在土壤?植物系統中的遷移轉化規律及影響因素,進一步分析調控劑的作用機理,探尋具有實際應用價值的調控劑配方及合理使用的方法,這不僅可以為重慶市農業土壤鎘污染的防治提供可靠的技術保障,而且對于其它重金屬污染的治理也有一定的理論意義。
