The results show that not only the growth of C. wenyujin in lime soil is possible, but also the biomass, yield of medicinal part, the content of oil from the tuber and its medicinal components are higher than those from red soil. The C. wenyujin from lime soil quickly assumes etiolation during initial growth period. Surprisingly, the lusty leafs of C. wenyujin planted in red soil turn to pale and brown flecks occur in the leafs with the fertilization of N, P, K. It is concluded that C. wenyujin can be planted in lime soil; C.

结果表明：温郁金不但可以在石灰土上生长，而且其药用部位的产量、莪术油的含量及莪术油中主要药用组分β-榄香稀等的含量都较大；石灰土上生长的温郁金在生长前期较快地表现出老叶明显发黄的缺肥症状，而红壤植株在追加N、P、K 3种大量元素后功能叶子呈现黄白色，且夹带有褐色斑点的缺肥症状；石灰土中Fe元素有效态含量比红壤低一个数量级，但在石灰土上种植的温郁金植株其Fe元素含量并不比红壤上的低。

The extracted contents of Cu, Pb and Cd in 3 kinds of soils using different extractant s were tested.

测定了7种浸提剂对3种类型土壤中重金属元素Cu、Pb、Cd的浸提量，分析了不同土壤类型条件下Cu、Pb、Cd元素间和不同元素下土壤间浸提率的相关性。

Factor analysis is applied to 3,061 samples of the surface soil of Chengdu basin after a progress of regression analysis, in which arsenic is used as dependent variable while other elements are used as independent variables. Elements with higher factor loading are selected to compose characteristic groups.

对成都盆地3061个浅层土壤样品以元素为变量进行砷回归分析，在回归模型的基础上进行R型因子分析，并选取因子载荷较大的元素作为特征元素组合。

Fiur is young, and his battle prowess untried, but he has a ferociousness like no other.

费拉天生具有控制火元素和烈火元素的本领，是元素城的重要将领。

If you do declare variables, functions, or namespaces at the top level of a package, the only attributes available at that level are public and internal, and only one package-level declaration per file can use the public attribute, whether that declaration is a class, variable, function, or namespace.

在包顶层定义的这些元素的属性只能为public和internal(只对包中的其他成员可见)，并且每一个文件中只能有一个包层面的元素定义为public属性，不管这个元素是类、变量、函数还是命名空间。

For lanthanides in Am at pH 2. 7～2. 8. According to empirical distribution ratio model and proposed calculation method, flow sheets are proposed for the separation of Am and fission product lanthanides from power reactor and production reactor waste respectively.

7级萃取、3级洗涤2级反萃的多级逆流分馏萃取实验表明HBTMPDTP-TBP-煤油能够很好地萃取分离镅和镧系元素，在pH值为2.7～2.8时，镧系元素中镅的分离系数大于5×10〓，镅中镧系元素的分离系数大于2.5×10〓。

If so, then the member initializes an object in the next available spot in preallocated memory. If there isn't a free element, then the vector is reallocated: The vector obtains new space, copies the existing elements into that space, adds the new element, and frees the old space.

如果有，该成员在预分配内存中下一可用位置初始化一个对象；如果没有自由元素，就重新分配 vector： vector 获取新的空间，将现在元素复制到空间，增加新元素，并释放旧空间。

The global topologic character of the graphics is the connection between nodes and graphics elements, which is revealed by the connection between node regions and bars.

扫描图象中图形元素由图段描述，图形元素相连接的节点变成了节点区域，图形的拓扑特征是图段与节点区域的连通性所反映的图形元素与节点的连接关系。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
