查询词典 atomic mass

The results were as follows:the mass fractions of the mineral nutrient elements in a part of the orchard plants were out of balance,especially the mass fractions of some trace elements such as B, Cu, Fe in the plants were higher; in the soilsof most orchards, the problems such as stronger acidity, higher mass fractions of readily available P, lowermass fractions of exchangeable base and lower mass fractions of available trace elements werefound.

结果表明，部分果园植株矿质营养元素质量分数存在失衡现象，尤其是植株的B、Cu、Fe等微量元素质量分数偏高。大多数果园土壤存在土壤酸性强、速效P质量分数高、交换性盐基质量分数低的问题，较多的果园土壤微量元素有效态质量分数偏低。

Its ultimate goal is to transform man into mass man or Thomas Pynchon's "SHROUD", the synthetic human, who has mass consciousness, mass belief and mass behavior, and to create one blandly ignorant but wholistic or conformist society.

它的目的是要把人们变成具有统一的意识、统一的信仰和行为，毫无个性的、托马斯·品钦所谓的&合成人&，把美国社会变成一个乏味无知、统一顺从的集体。

The efficiency of mass transfer in 60% fraction of hole is higher than in 40% fraction of hole. When gas/liquid ratio is lower 10, the efficiency of mass transfer in new sieve baffle tray is higher than in traditional tray.A three-dimensional quasi-single phase computational fluid dynamics program with the RNG- turbulence model is presented for evaluating the performance of the new sieve baffle tray. The special feature of this model is taking into account the influence of heat transfer during the mass transfer and the influence of mass transfer in computing the flow field.

建立了以RNG模型为基础的三维拟单相流模型，该模型与其它研究者所建立的模型的最大进步是，前人在塔板流场的计算中没有考虑传质的影响，并且在传质过程中没有也没有考虑传热对传质产生的影响，实际上在传质过程中，抛开传热来计算和研究传质是不准确的，因为在传质过程中伴随着传热，并且传热和传质是互相影响、互相制约的，本文所建立的传热与传质模型，把传热和传质进行了有效的藕合。

Of course, a periodic table cannot be complete unless it has the atomic mass of the element and so this table uses the rank of the web page as it's "mass".

当然，在元素周期表中，可以是不完整的，除非它拥有原子质量的元素，所以本表使用秩该网页，因为它的"地下"。

From c. 1900 until 1961, the reference standard was oxygen, with a value of 16, and the unit of atomic mass was defined as 1/16 the mass of an oxygen atom.

大约从1900～1961年，氧曾作为原子量的参考标准，那时指定氧的原子量为16，因而原子质量单位定义为氧原子质量的1/16。
