(1)it is no good crying over spilt milk. 覆水難收 (2)對著灑掉的牛奶哭泣沒什么用處。 (3)分析：這是一個英國的諺語。it是形式主語，crying over spilt milk. 是真正的主語，為避免頭重腳輕，把真正的主語后置。希望對你有所幫助。祝你進步。

The incorporation of silicon from the quartz-made growth chamber， characteristic of NIRIM-type reactor is insignificant in our samples， if any. The peak at 1.681 eV from the Si–V defect is totally absent from our films (not shown here)， which supports the good quality of these films. The improvement of the crystalline quality of {111} films is explained by the weak ion bombardment of the sample during its growth outside the plasma ball. Raman measurements (not shown in this work) have also confirmed the high crystalline quality of our films， in particular in the low doping range. Very high boron concentrations (up to 5×1021 cm?3) have been reached at this growth position， outside the plasma ball. 展開

A reversed-phase ion-pairing high-performance liquid chromatography (RP-HPIPC) method for the separation of a complex mixture of heparin-derived oligosacchrides has been developed by a stepwise optimization of the mobile phase， in which the concentration of ion-pairing reagent， mobile phase pH， and acetonitrile concentration were varied. The resolution of more than 30 oligosaccharide components was obtained， under optimized conditions， in an analysis time of less than 30 min. This represents the first RP-HPLC method that can separate a complex mixture of both small and large sulfated oligosaccharides in a single chromatographic step. The heparin-derived oligosaccharides， in this mixture， can also be separated under a second set of RP-HPIPC conditions using a volatile ion-pairing reagent， tributylammonium acetate， to aid in the recovery of individual sulfated oligosaccharides. Moreover， it was possible to replace sodium chloride gradient， required for eluting highly sulfated oligosaccharides， with a fixed， low concentration of a volatile salt， ammonium acetate， by utilizing an acetonitrile gradient. This solvent system might make it possible to directly interface this RP-HPIPC separation with mass spectral analysis. ??2003 Elsevier B.V. All rights reserved.

Nano-sized Beta zeolites， with a crystal size of 80–100 nm， were synthesized via surface wet method. The nano-sized Hbeta zeolites exhibit much higher activity and stability in the Friedel–Crafts acylation of anisole and toluene with acetic anhydride than theconventional zeolites of largeparticle size.The smallcrystalsize of nano-sized zeolitesmay bringon more accessible activesites and then enhance the catalytic activity. The exposed pore openings in nano-sized zeolites allow a fast desorption of heavy products from the catalyst and can then reduce the occupancy of active sites by the adsorption of products ，this can then alleviate the catalyst deactivation and improve the catalyst stability deactivation and improve the catalyst stability. 急用在線等拒絕用自動翻譯因為這個誰都會如果有超級好用的自動在線翻譯或軟件也可以推薦展開

DARPA has been at the forefront of the aggressive FCS initiative. We are conducting demonstrations of advanced prototypes， including unmanned ground reconnaissance and attack platforms; low-cost tactical precision munitions; small UAVs that support operations in urban and mountainous environments; and sensors that can detect vehicles camouflaged under dense foliage. A Defense Acquisition Board scheduled for May could allow FCS to enter System Development and Demonstration under Army management this year. This will enable the Army to field an FCS Unit for operational testing in FY 2008， with the first Unit of Action ready for operational deployment by 2010. DARPA is also conducting three unmanned air combatant programs: the Unmanned Combat Air Vehicle (UCAV) with the Air Force， UCAV-N with the Page 5 of 14 Navy， and the Unmanned Combat Armed Rotorcraft program with the Army. These aircraft will be teamed with manned systems on the ground and in the air to transform how the Air Force suppresses enemy air defenses， how the Navy suppresses enemy air defenses and conducts extended surveillance， and how the Army conducts armed reconnaissance and attack. 展開

Plant material and culture conditions have been described (7). Briefly， a diploid tissue culture line， WOO1C， of wild carrot， Daucus carota L.， was maintained in Murashige and Skoog medium supplemented with 0.1 mg of 2，4-dichlorophenoxyacetic acid (2，4-D). To regenerate plants from the culture， callus tissue was transferred to the same medium devoid of 2，4-D (embryogenic medium). All experiments were performed with cultures grown in liquid medium. For convenience， cultures grown in 2，4-D-containing medium are referred to as "callus cultures"， and those grown in medium without 2，4-D as "embryo cultures." The growth of callus cultures was measured by the sidearmturbidity method (7). The number of cells at any time point of growth was estimated from turbidity in a Klett-Summerson calorimeter and was expressed in arbitrary units. For example， Klett 100 corresponds to ="2 X 106 cells per ml. The relationship is linear up to Klett 150 in our Klett-Summerson colorimeter. Suspension cultures ofWOOLC cell line are normally maintained at cell densities between 106 and 107 cells per ml in 0.1 mg of 2，4-D per liter (high-density culture) in shake flasks. During a quantitative study on embryogenesis， we found that maximal embryo production can be achieved by first incubating the culture at high density in medium without 2，4-D for one generation time and then diluting it to 2-3 x 104 cells per ml (low-density culture). To compare cultures of comparable density， callus cultures and embryo cultures were subjected to the same procedure. To initiate low-density embryo or callus cultures， an 8-day-old high-density culture grown at the logarithmic phase was washed three times with fresh callus or embryogenic medium and resuspended at 8 x 105 cells per ml for one generation (3 days) in its corresponding medium. It was then diluted to 2 x 104 cells per ml; 20 ml of the culture was incubated in a plastic Petri dish (9 cm in diameter) at 240C. The morphogenetic events of the cultures were examined and photographed under a dissecting microscope. 請不要用google的那個，我看不懂~~ 展開

環(huán)境英語文獻翻譯急用: Thereisagrowinginterestindeterminingmercury(Hg)levelsinthemarineenvironmentaswellasinfishforhumanconsumption.Methylmercury(MeHg)inparticularisthemosttoxicandbioaccumulati... There is a growing interest in determining mercury(Hg) levels in the marine environment as well as in fish for human consumption. Methyl mercury(Me Hg)in particular is the most toxic and bioaccumulative form of mercury in food webs and it is the predominant chemical form making up 80%-90% of the total mercury present in fish muscle tissue.Hence，fish and other organisms at the end of the food chain constitute the major source of MeHg in the human . As outcome of this risk，MeHg has been classically monitored in fish， and methodologies for mercury speciaion have increased significantly since the early 1990s. Currently， microwave-assisted extraction (MAE) has provided an efficient alternative strategy to conventional techniques for solvent extraction of a large amount of organometals compounds.The analytical techniques most frequently applied for Hg speciation analysis involve GC(GasChromatography) ， GC-CICP-MS(Gas Chromatography -CInductively Coupled Plasma Mass Spectrometry) supercritical fluids chromatography (SFC)，ion chromatograph(IC)， HPLC-CCVAAS(High Performance Liqui Chromatography-Cold Vapor Atomic Absorption Spectrometry) or ICP-MS systems .Several authors recommended a back-extraction of mercury species from organic solvents to cysteine or sodium thiosulphate aqueous solutions .Because MeHg is the most common organomercury compound in biological materials ，here we offer a new simple and cost-effective method to determine MeHg. Basically， this method combines the microwave assisted extraction followed by clean-up with cysteine acetate solution and MeHg quantification by a direct mercury analyzer (DMA). 展開

哪位英語高手幫幫忙，翻譯英語文章！謝謝1: 英語高手，謝謝了！ThecatalystsupportwasimpregnatedwithacetonesolutionofRuCl3.nH2Ouptorutheniumcontentof4w%，understirringfor6h.Afterconcentrationinarotaryevaporator，theobt... 英語高手，謝謝了！ The catalyst support was impregnated with acetone solution of RuCl3.nH2O up to ruthenium content of 4 w%， under stirring for 6 h. After concentration in a rotary evaporator， the obtained material was dried in air at 383 K overnight and subjected to preliminary reduction with a 1N2/3H2 stream at 698 K， and then cooled in 1N2/3H2 atmosphere. The potassium promoter was introduced by incipient wet impregnation with KNO3 solution at room temperature with molar ratio of K+ /Ru = 5/1. After stirring for 6 h and infusing for 24 h， the samples were dried in a rotary evaporator at 343K and then dried in the air at 383K for 12 h. The ammonia synthesis activities of the catalysts with about 35-60 meshes were evaluated by 1N2/3H2 flow of 2100 mL/h at 0.2 MPa from 623 K to 773 K. The amount of effluent ammonia was determined by titration method. As we can see from the Table 1， under the same reaction conditions， the catalyst K-Ru/Mg(Al)O exhibited the highest activity， 38.42 mL NH3?h-1?g-1 at 673K， 3 times more active than K-Ru/MgO， 12.88 mL NH3?h-1?g-1 at 748K. This means that selection of supports takes great effects on the activity of catalysts. The ammonia synthesis activity of different supports are K-Ru/Mg(Al)O > K-Ru/Mg-Al-Ca(1) > K-Ru/Mg-Al-Ca(2) > K-Ru/Al2O3 > K-Ru/CaO > K-Ru/MgO. The combinatorial supports showed higher activity than single supports. However， the sequence of temperature corresponding to the highest activity is just opposite to that of the activity. The optimal temperature for K-Ru/Mg(Al)O， 673K， is the lowest of all， on the contrary， that of K-Ru/MgO is the highest， 748K. The Mg(Al)O has a larger surface area of 140.95 m2?g-1 ， similar to γ-Al2O3， 110-180 m2?g-1 . The other two combinational supports have little surface areas but higher activities than Al2O3. It suggested that the activity of the catalyst is influenced not only by the dispersion of Ru crystals but also by the crystal structure of the supports.
