查询词典 U

In pre-equilibrium fission fields, n＋~(238)U and p＋~(208)Pb reactions are studied by numerical solution of Smoluchowski equation, and their results can be extended to the fission reactions of those nuclei in actinium and sub-actinium family.

关于预平衡裂变，主要通过数值解Smoluchowski方程，对两个典型核反应n＋~(238)U和p＋~(208)pb的裂变过程进行了研究，并把结论推广到锕系核和重核的情况。

Let G be the domain whose inverse image is the cross section of u definedin (H1) where the mapping is affine,g and ψ are smooth functions and g＞0,thenthere is a unique smooth convex-monotone function which satisfies the followingproblem 〓Furthermore,if 〓 where C is a constant,ψis an affine function,〓 is astrictly interior sub-domain of G in the sense of"parabolic distance",then

若G为按（H1）中定义的u的截影经仿射变换而得的区域，g和〓为光滑函数且〓，则〓存在惟一的凸单调光滑解。若〓常数，〓仿射函数，〓为G在"抛物距离"下的严格内子域，则

The results showed that the addition of 10 U/g cellulase in the residual distiller′s grains could effectively increase the content of reducing sugar after 5 h water bathing in water bathing pot at 58 ℃, the alcoholicity by the fermentation of the residual distiller′s grains could reach 4.67 %vol, and liquor yield could reach 31.39 %(increasing by 2.61 % than untreated distiller′s grains).

结果表明，在残糟中添加纤维素酶10 U/g，于58 ℃的水浴锅中保持5 h，可以提高还原糖的含量，残糟发酵酒精度达到4.67 %vol，出酒率达到31.39 %，出酒率比原糟提高了2.61 %，蒸馏出的产品达到蒸馏白酒各项卫生指标，达到优质酱香白酒的要求，提高了酱香型白酒酒糟的利用价值。

Hahahhahaha alexia i'm just as pissed off as u are but give them their due…they do put a lot of hard work into the site.

hahahhahaha失我只是作为pissed小康为U ，不过是给予他们应有的……他们这样做投入了大量的辛勤工作，进入网站。

The crystal-chemical properties and the genesis of the allanite have been disscussed, in addition, the radioative decay of Th and U and the oxidation cause rare-earth elements to be released from its lattice to d...

认为本区的褐帘石是部分变生的。变生的机理是因为其晶格中含放射性元素U，Th高，且这与褐帘石的选矿性能有重要关系。

2The studies on the appearance typomorphism, physical typomorphism, inner structure typomorphism and chemical typomorphism of the zircon and garnet, and the result of U-Pb isotopic age dating of zircon indicate that the zircons are meta-morphogenic genesis but two or three of them are magmatic genesis and most meta-morphogenic zircons have a basic magmatic zircon core which was generated in Stage of Yanshand and Indo-Chinese epoch. The genesis and origin of the garnet is very complicated. The garnets are main almandine with high Fe and Mg content and were proposed their souce rocks are mostly regional mid-degree-metamorphic rocks.

2研究锆石和石榴石的形貌标型、物性标型、内部结构标型以及成分标型特征和锆石U-Pb同位素测年结果表明，锆石除少数几个为岩浆锆石外，绝大多数是变质锆石，且中间多有形成于燕山-印支期的基性岩岩浆锆石残核；石榴石的成因及来源是比较复杂的，以铁铝榴石为主，且铁铝榴石中Fe、Mg的含量较高，推测其源区母岩主要以中级区域变质岩为主。

The oxidation of Ce results in loss of REE, U, and alpha decay product Pb during the alteration of the pyrochlore.

这表明在烧绿石蚀变期间，Ce的氧化导致了稀土元素、U及α衰变产物Pb的损失。
