And the major results and some new viewpoints were presented as follow : 1 ) sediment content of cn tillage system in runoff process is substantially low compared to st under rainfall with high intensity, showing cn bear the efficient capacity of control soil loss. nevertheless, when soil is saturated, the runoff intensity of both tillage systems is near, implicating cn has the limited function of reducing runoff. 2 ) based on the case analysis of observed all rainfall - runoff generation processes, a ) the initiation time hysteresis of surface runoff generation is notable when rainfall fall upon the unsaturated purple soils, which is attributed to the property of rapid water sorption and much non - capillary porosity
經近幾年的觀測和理論分析，取得了以下結果和創新的認識： 1 ）在降雨強度較大的情況下，保護性耕作制? ?聚土免耕的產沙強度明顯較常規耕作制? ?順坡耕作的小，說明聚土免耕耕作制防治土壤流失是有效的；但當土壤達到飽和后，聚土免耕的徑流強度與常規耕作的差異較小，產沙強度也增大，因此，聚土免耕防治水土流失的能力是有限的。 -
The effort of manganese removal was studied and the kinetics of manganese removal was tried to establish. the factors of dissolved oxygen concentration, fe2 + concentration, ph, p concentration and closing of the filter were studied to evaluate their effort for biological manganese removal, and the correlation of residual manganese and oxidation - reduction potential was also discussed. as the iron content of water was high, experiment results showed that the reaction was zero order, as the iron content of water was low, the reaction was first order. the time needed for the cultivation of biological manganese removal was 60 70 days. the filter operated at the filtration rate of 8 10m / h, silica sand of effective size 0. 95 1. 25mm filled the filter to a depth of 1200mm
試驗結果表明，成熟后濾砂表面濾膜的x射線衍射圖譜與mno _ x ? 5h _ 2o （ x = 1 . 86 ）的x射線衍射圖譜一樣，濾膜成熟后的結構在進水物質不發生變化的情況下不發生變化;合適的碳磷比對生物除錳有明顯的促進作用，試驗條件下的投磷量不會對出水造成二次污染;生物除錳需要亞鐵的參與，亞鐵的存在除了能夠促進微生物分泌胞外酶並刺激其活性外，還通過鐵離子的變價傳遞電子，催化錳離子的氧化反應，從而促進對二價錳的降解。 -

Currently, more and more chinese citizens enjoy to “ home gardon ” in their apartments. they usually pour their plant by “ tap water ”. we know that it would be better for the growth of plant if we pour them by “ rain water ” or “ river water ” instead of “ tap water ”, but many of chinese citizens living in apartments are not able to collect and store enough “ rain water ” in the days of rain cause their limited living space. therefore i offer those businessmen who selling “ soil of gardon ” can also collect and store “ rain water ” and “ snow water ” in the special weather days and sell them to the families of enjoying gardon in apartments. this sort of commercial action would be low cost. that would solve the health problems of plant cause poured “ tap water ” and bring benefits to businessmen. the most important thing is : if this commercial action would have developed for a long time so that it could be practiced all over chinese cities, our country would save large quantity of “ tap water ” every year
當今的城市中，綠色植物已經成為家居美化中必不可少的因素，隨著人們越來越崇尚「熱愛綠色、回歸自然」的生活方式，家庭園藝將會被更多的家庭所熱衷，粗通園藝的人都知道，用雨水、河水澆花遠勝于自來水，可是由於時間和居住條件所限，城市居民很難在下雨的時候收集足夠的雨水儲存起來用於家庭園藝，建議售賣園藝土等園藝用品的市場商戶，能在雨雪天收集大量的雨水、雪水儲存起來，賣給熱愛養花的家庭，價廉物美，一方面可解決公寓樓中中長期用自來水澆花帶來的不良問題，一方面給自己帶來些收益，最重要的是： 「涓涓細流，匯成江河」 ，如果這種設想能發展成長期的商業行為，並在各大城市都實行起來，那每年能節約多少自來水呀！ -

I had been now thirteen days on shore, and had been eleven times on board the ship ; in which time i had brought away all that one pair of hands could well be suppos d capable to bring, tho i believe verily, had the calm weather held, i should have brought away the whole ship piece by piece : but preparing the 12th time to go on board, i found the wind begin to rise ; however at low water i went on board, and tho i thought i had rumag d the cabbin so effectually, as that nothing more could be found, yet i discover d a locker with drawers in it, in one of which i found two or three razors, and one pair of large sizzers, with some ten or a dozen of good knives and forks ; in another i found about thirty six pounds value in money, some european coin, some brazil, some pieces of eight, some gold, some silver
可是，我相信，假如天氣好下去，我一定可以把全船拆成一塊塊的木板搬到岸上。當我正準備第十二次上船時，開始颳起了大風，但我還是在退潮時上了船，盡管我以為我已搜遍了全船，不可能再找到什麼有用的東西了，結果還是有新發現。我找到了一個有抽屜的柜子，在一個抽屜里，我找出了兩三把剃刀，一把大剪刀，十幾副刀叉在另一個抽屜里，還發現了許多錢幣，有歐洲的金幣，有巴西的，有西班牙銀幣，我感到好笑。 -
I had the biggest maggazin of all kinds now that ever were laid up, i believe, for one man, but i was not satisfy d still ; for while the ship sat upright in that posture, i thought i ought to get every thing out of her that i could ; so every day at low water i went on board, and brought away some thing or other : but particularly the third time i went, i brought away as much of the rigging as i could, as also all the small ropes and rope - twine i could get, with a piece of spare canvass, which was to mend the sails upon occasion, the barrel of wet gun - powder : in a word, i brought away all the sails first and last, only that i was fain to cut them in pieces, and bring as much at a time as i could ; for they were no more useful to be sails, but as meer canvass only
但我並不以此為滿足，我想趁那隻船還擱淺在那兒時，盡可能把可以搬動的東西弄下來。因此，我每天趁退潮時上船，每次都運回些東西。特別是第三次，我把船上所有的粗細繩子通通取了來，同時又拿了一塊備用帆布，那是備著補帆用的我甚至把那桶受了潮的火藥也運了回來，一句話，我把船上的帆都拿了下來，不過我都把它們裁成一塊塊的，每次能拿多少就拿多少，因為現在，我需要的不是帆，而是帆布。
