l lab 解釋
實驗室
  • l : L-beam, L-iron 不等邊角鋼。L,￡＝ 〈拉丁語〉 libra （＝ pound）。
  1. ( 2 ) the results of the rainfall - affected runoff scouring experiments in lab. when the rainfall intensity was less than l. omm / min, the soil erosion caused by the combination of rainfall and the upslope runoff was more than that caused by only the simulated rainfall. when the rainfall intensity was more than 2. 0mm / min, the upslope runoff strengthened the effect of the runoff yielded in the local area on the dyke slope surface, and the effect increased with an increase of rainfall intensity

    2 、室內模擬降雨+放水沖刷試驗結果雨強小（如i 1 . 0mm min ）時，上游注入水量對戧坡侵蝕作用比降雨在戧坡上所產生徑流的侵蝕大；雨強大時（ i 2 . 0mm min ） ，上游水量下泄與當地降雨徑流一起增強對戧坡面的侵蝕作用，雨強越大，侵蝕作用也越大。
  2. In the process of study for the extracellular cam, the research in our lab indicates that cambps also possibly exist in cell wall area. for the first time, an extracellular ca ~ ( 2 + ) - dependent cambp ( named : ecbp21 ) was purified from 0. 1mol / l cacl _ ( 2 ) extracts of angelica dahurica suspension - cultured cells ( tang et al. 1996 )

    我室在對植物細胞外cam的研究過程中，發現細胞外還可能存在cambps ，並首次從白芷懸浮培養細胞外純化了一種依賴ca ~ （ 2 + ）的、分子量約為21kd的細胞外cambp （ tang等， 1996 ） （定名為： ecbp21 ） 。
  3. When the saline water ( < 3g / l ) infiltrated to 45cm, the top soil of 0 - 37cm was desalinized, when the saline water of 3g / l infiltrated, the desalinized depth was 0 - 15cm. moreover, sar of top soil increased with the sar of the infiltration water. 3. through lab experiment, the characteristics of soil water and salt movement under different initial soil moisture content were analyzed

    當濕潤深度為45cm時，小於3g l的微鹹水入滲后， 0 - 37cm土層處于脫鹽狀態，而3g l的微鹹水入滲， 0 - 15cm土層處于脫鹽狀態， 15cm - 35cm土層含鹽量基本等於初始含鹽量，但濕潤鋒處含鹽量很高。
  4. In this article, through lab and engineering site trials that the physical data of new type pipe materials is corrected, the results are as follow : ( l ) the expansion coefficient of new plastic pipe materials is more large than that of iron pipe. ( 2 ) new plastic pipe materials have different heat - resisting character and according to the water temperature to choose pipe materials ; ( 3 ) the loss of head of water for new type pipe materials is more smaller than iron pipe and also correct the loss of head of water that calculated by theory ; ( 4 ) probing into the press - resistance character of new plastic pipe materials

    本文通過試驗室試驗及工程現場試驗，對新型給排水管材的幾個重要的物理性能參數進行實驗測定，糾正了以往的錯誤認識。研究結果表明： （ 1 ）新型塑料管材線脹系數遠遠大於鋼管和鑄鐵管，設計和施工中要嚴格考慮管道的伸縮； （ 2 ）新型塑料管材耐高溫性能各不相同，需根據管內水溫選定管材； （ 3 ）新型管材水頭損失遠小於鋼管，並對原水頭損失計算公式進行了修正； （ 4 ）對于塑料管材的耐壓性能進行了探討。
  5. Int ' l trade virtual lab to be a base for ft internship

    學校國際貿易模擬實驗室應成為培養外經貿人才的基地
