The composi tional change profiles of monazite demonstrate a heterogeneous distribution of e lements La, Ce, Nd, P, Th, Si, Ca and U. This was caused by the differences in geological environments, temperatures, pressures and compositions of the hy drothermal solutions.

根据微区剖面(0.18mm)元素分布曲线,指出了La、Ce、Nd、P、Th、Si、Ca和U等元素表现出8~10个微环带成分不均匀分布的特点,并认为成矿溶液的地质环境、温压和微量元素含量变化是不均匀分布的主要原因。

However, the formation of metal chelation at one or two side of biphenyl resulted a pair of enantiomers of monometallic or bimetallic complexes. Moreover, if the coordinating groups have chiral element (e.g., chiral oxazolines), the diastereomeric metal complexes will be formed.

而且,如果配位基团上带有手性元素,它们跟金属配位后得到一对非对映异构体,由于手性元素的影响,形成这一对非对映异构体的能量是有差异的。

Based on bi-pole(the element are +1 and -1) coded serial, we present monopole(the elements are +1 and 0) coded serial.

在双极(元素为+1和-1)序列的编码激励基础上,提出了单极(元素为+1和0)序列编码激励。

An element of the array is accessed by its index while an element is obtained in memory by its address. So the conversion method from array index to memory address must be generated. In this paper, a novel algorithm of address generation using logic operation for multidimensional array is proposed.

行为级描述中通过数组下标对数组元素进行操作,而存储器的操作要通过存储单元地址来实现,因此需要将数组元素的下标转换成对应的存储单元的地址。

A formula for non-dimensional synthetic electronegativity was obtained by multiple regression analysis. The correlation coefficient (R=0.9844) and test of significance Sig.

采用回归分析法,对周期表中除零族、氢及放射性元素之外的77种元素的Pauling电负性X(下标 P进行回归分析,得到了一个无量纲的综合性的电负性计算公式,相关系数(R=0.9844)和回归方程F检验的显著性水平Sig。

If the box was omitted and there were multiple children of the root window, they would be laid out vertically by default, one under the other.

如果没有box元素,而window又有多个直接子元素,那么他们默认会从上到下竖向排列。

As investigated, the shape of the fruit was mainly rotundity, and the color of the fruit were red, black, yellow, mauve. Variation coefficient of mineral elements, which revealed wider variation range and rich genetic diversity. Among them, Fe, the content and the variation coefficient of which was the highest(2.12 mg·100g-1 and 26.99%), it has large potential for futher selection. Ripe fruit of 12 wild myrobalan plum seedlings were analyzed using head space-solid phase microextraction and gas chromatography-mass spectrometry. The results showed considerable genetic variations in these aspects: The total content of volatile components, the classes and contents of each compounds classes, the segregation ratio, and content of main components. There were 83 compounds in total belonging to 6 classes detected in 12 wild myrobalan plum seedlings, including esters, alcohols, ketones, aldehydes, heterocycle and Hydrocarbons. Among them, Formic acid, hexyl ester, the content of which was the highest(4.33 μg·g-1),was important character impact odors.

结果表明,①新疆野生樱桃李实生株系的果实形状主要为圆形,少数为椭圆形、卵圆形、卵形和宽卵形,果实颜色有黄色、红色、紫红色和黑色等4种类型,野生樱桃李果实纵径、横径、单果重、果形指数以及可溶性固形物含量均存在一定程度的变异,遗传多样性较为丰富,其中以单果重的变异系数最大(9.13 %);②新疆野生樱桃李实生株系果肉组织的Zn、Ca、Mg、Mn、Fe及Cu等6种矿质元素含量变异丰富,其中以Fe元素的含量(平均值为2.12 mg·100g-1)和变异系数(26.99%)最高,进一步筛选高铁性状单株的潜力很大;③从新疆野生樱桃李12个实生株系中共鉴定出醇类、醛类、酯类、酮类、烃类及杂环类等6类83种挥发性化合物,各实生株系挥发性化合物总含量、挥发性化合物种类及其含量以及主要挥发性化合物分离比率与含量等存在广泛的遗传变异,遗传多样性较为丰富,其中以甲酸己酯含量最高(平均值为4.33 μg·g-1),是野生樱桃李果实香气形成的重要特征性化合物。

Owing to the fact that uranium is 106~107 higher than that of neptunium ,it is extremely difficult to remove uranium from neptunium without any loss of neptunium ,either from the theoretical calculation or from practical experience .

不论从理论计算上,还是从实际的工作经验上,两种待分离的元素在数量级上相差10~6~10~7,要将其中含量高的元素除去,而微量元素不损失是很困难的。

The results indicated as follows:the total nutrient elements accumulation of various Slash Pine stands amounted to 1273.83-1615.88kg/hm2,of which stem occupied about 60%. The nutrient retention accounted for 111.46-133.39kg/hm2*a,which is higher than that of either Chinese fir or Masson pine plantation. The nutrient return equalled to 90.43-105.09kg/hm2*a.
