The fusion mechanism of large deuterium clusters ( 100 ~ 1000 atoms / per cluster ) in super - intense ultra - short laser pulse field , coulomb explosions of micro - cluster in solids , gases and large - size clusters have been studied using the interaction of a high - intensity femtosecond laser pulses with large deuterium clusters , collision of high - quality beam of micro - cluster from 2 . 5mv van de graaff accelerator with solids , gases and large clusters 摘要用2 . 5mv靜電加器提供的高品質微團簇束與固體、氣體和大尺度團簇（ 100 - > 1000原子團簇）碰撞，超強飛秒激光與大尺度氘團簇相互作用，研究微團簇在大尺度團簇中的庫侖爆炸特性，研究超短超強激光場中大尺度氘團簇的聚變機理。

Researches into the nuclear fusion reactions has created a need for handling the deuterium tritium fuel employed , and cryogenic fractional distillation was selected as one of the best process for making the required separations due to relatively large separation factors , low power consumption , high throughputs , relatively short start - up times , and flexibility of design 受控聚變的研究已給人類展示出取得更加安全、清潔，而且是無限豐富的能源的美好前景。在廉價制取聚變燃料氘以及提高核能原料利用率的方法中，低溫精餾被認為是最經濟可行的分離氫同位素的方法。

According to theory of the environmental isotope tracer and theory of deuterium excess ( d - excess ) parameter with the atmospheric water and the groundwater , the dissertation has comprehensively researched on the regional karst water and the pressure - bearing karst water in deep maoba syncline in virtue of routine geologic and geochemistry investigation 根據環境同位素示蹤、大氣降水氘過量參數和地下水氘過量參數演化理論，結合常規地質、地球化學工作，對該地區域巖溶水和毛壩向斜段核部深層巖溶承壓水進行了綜合分析研究。

Using the theory of environment isotope and deuterium excess ( d - excess ) parameter , we found the cause of formation of spring ground water in mianzhu area , including the water origin and transportation process and recharge and discharge relationship of various water bodies and hydrogeologic units ; 2 . the type of terrestrial heat system is low - medium temperature system of convective type ; 3 . this paper valued the si well ( including the scale of geothermal water , exploitation potential and evaluation of medical treatment mineral water ) ; 4 論文以同位素地球化學和水文地球化學的理論、技術為基礎，結合綿竹三箭水s _ 1井及其鄰區溫泉地下水形成的區域地質構造背景、地層巖石組合特征及主要水文地質條件，剖析了研究區內可能存在地熱溫泉水的“儲、蓋、通、源”基本條件，對該區各水體的氫、氧同位素、氘過量參數、氚含量以及水化學分析資料進行了系統地研究，取得了以下成果。

It also appears to solve the deuterium problem but only if the rocky materials out near the earth ' s present orbit picked up some local water from the solar nebula ( the cloud of gas and dust surrounding the young sun ) before they accreted to form the earth 同時，看上去它也解決了氣含量的問題? ?但是只有當外來的巖石物質處于地球現今軌道附近時，并且在它們增生形成地球之前，從太陽的星云里(圍繞著年輕太陽的氣體和塵埃)獲取了水時，這個問題才最終得到解決。

Some new laboratory studies of the manner in which deuterium gets exchanged between hydrogen gas and water vapor have indicated that the water vapor in the local region of the solar nebula would have had about the right proportion of deuterium to balance the excess deuterium seen in comets 最新的對于氫氣與水汽間氖交換方式的實驗室研究表明，處于太陽星云里的水汽剛好有適當的氛含量來平衡彗星里所含的過多的氙。

First , the apparatus of spectral irradiance calibration is set up , and ultraviolet spectrum band uses a standard lamp offered by standard metrological institute of china , while vacuum ultraviolet spectrum uses a deuterium transfer lamp 地面輻射定標分為光譜輻照度定標和光譜輻亮度定標。光譜輻照度定標中選用了鹵鎢燈作為250nm 400nm標準光源，氘燈作為200nm 300nm的傳遞光源。

The type of reactor that will continue to dominate for at least two decades , probably longer , is the light - water reactor , which uses ordinary water ( as opposed to heavy water , containing deuterium ) as the coolant and moderator 在未來起碼20年間（可能還要更久） ，輕水反應器將仍舊是主要的反應器類型，這種反應器以普通的水（而非含有氘的重水）來當做冷卻劑與緩和劑。

The dt - mini - 2 - gs deuterium tungsten halogen light source combines the continuous spectrum of an rf - excited deuterium uv light source and a tungsten halogen vis - nir light source in a single optical path Gs氘-鎢鹵組合式光源集成了一個用于紫外光的射頻激發氘燈光源和一個用于可見光/近紅外光的鎢鹵光源，能夠在一個光程中提供紫外/可見/近紅外波段的連續輸出光譜。

That doesn ' t mean the bomber is weak against defensive structures , but he ' s too slow , costs a lot of deuterium to fly around and to be built , and isn ' t good for raiding attacks - only for bashing strategies 不是說它沒辦法消滅防御建筑，而是因為它太慢，消耗太多重氫在飛行和建造上，也不適合用在掠奪戰術，只有在壓制玩家的時候才有用。

When deuterium content is analyzed by mass spectrometry ( ms ) of digested peptides , corrections frequently need to be made for back - exchange that occurs during digestion , separation , and analysis 當用質譜( ms )分析消化的肽段中的氘的含量時，通常需要對消化、分離和分析過程中的返交換（ back - exchange ）進行校正。

It is designed to cause thermonuclear fusion in tiny pellets of deuterium ( so small that they would not be covered by the test - ban treaty ) and is expected to be completed in 2009 該系統是用來設計來在微型氘球（該微型球小得連禁核協議中都沒有提到）中引發熱核核聚變的，并預計在2009年完工。

A mixture of meteoritic water and cometary water would not work either because this combination would still contain a higher concentration of deuterium than is found in the oceans 隕星水和彗星水的混合也不可能提供地球上的全部水源，因為這種混合水與現在的海水相比，仍然有著較高的氖含量。

Deuterium for hydrogen exchange at amide sites in proteins is a well - established means of probing the stability of certain proteins and the effects of interactions with ligands and other proteins 肽鍵位置上以氘代氫是檢測某些蛋白質穩定性及其與配基或其他蛋白質相互作用的成熟方法。

We know this because the ice in the comets contains twice as many atoms of deuterium ( a heavy isotope of hydrogen ) to each atom of ordinary hydrogen as we find in seawater 因為我們知道彗星上冰的氛原子(氫的一種重同位素)與氫原子(現代海水中常見的氫原子)的比值是海水的兩倍。

This is sometimes called “ retrodiction . “ for example , the big bang theory makes very precise predictions about the primordial abundances of hydrogen , helium , and deuterium 這有時被稱為“追溯” 。例如，大爆炸理論對原始時期氫氣，氦氣和氘的大量存在做出了非常精確的預測。

The predictability provides potentially new means of improving site specificity of ms analysis and new means of assigning nmr resonances for deuterium content analysis in peptides 這種可預測性提供了可以提高ms分析的位置專屬性和進行肽段氘含量分析nmr譜峰歸屬的新途徑。

The dt - mini - 2 - gs includes a shutter as well as switches for all functions ( deuterium on and off ; tungsten halogen on and off ; and shutter on , off and ttl ) Gs僅需一個快門、一個開關就能完成所有功能（可控制氘燈的開關、鎢鹵燈的開關、快門的開關和ttl的開關） 。
