歙县蛇绿岩壳层组合属于钙碱性和拉斑玄武岩间过渡系列，具类似的微量及稀土元素比值和稀土元素配分模型，且大离子亲石元素和LREE高度富集。

After studying this phenomenon, the author finds that, the covariance matrix of the complex expressions of horizontal gradients of the disturbing gravity field elements has a structure of blockwise repetitive Toeplitz matrix, though the covariance within the disturbing gravity field elements is still anisotropic. Therefore, the collocation problem of the complex combination of horizontal components is similar to that of gravity anomaly, which makes the degradation be able to be completed by FFT transformation matrix.

作者研究发现，利用水平梯度的复组合，即复数表示后，扰动重力场元复组合之间的协方差函数尽管还是各向异性，但它们对应的协方差矩阵却具有分块 Toeplitz 循环阵的结构，因而水平分量复组合的配置问题与重力异常的配置问题相似，可以利用傅立叶变换矩阵进行降阶处理。

This thesis mainly expounds an analytical method in structure of the lexicographical sememic description elements, namely the structural trichotomy to the lexicographical sememic description elements.

本文主要阐述了一种对辞书义位描写要素的结构进行分析的方法，即辞书义位描写要素的结构三分方法，该方法将辞书中的义位描写要素从结构上分为核心要素、主干要素、标识要素。

On the basis of the advantages of the previous distillation calculation algorithms, by eliminating the non—zero elements to the two sides of the tridiagonal band of elements in the component material balance equations by correlation of the draw rate from the main column to the sidestrippers and the return vapor stream from the sidestrippers to the main column, it changes these equations into a typical form of the tridiagonal matrix, and uses the simultaneous convergent strategy of the main column and the side strippers to speed the algorithm convergent rate.

在吸收前人蒸馏计算算法优点的基础上，通过求解主塔抽出到汽提塔的量和汽提塔返回主塔的蒸汽流之间的关联，以便消除组分物料平衡方程组系数阵中的三对角线两边的非零元素，使它转化为典型的三对角矩阵形式，而且使用主塔和汽提塔同时收敛策略，加快了算法收敛速度。

The results show that this kind of roughening elements can possess a wide range of roughness, and the hydraulic resistance decreases with the increase of space between roughness elements, but reduces slowly to a constant, and that flow enters into the turbulently rough zone when Reynolds number reaches about 3 500, in which the hydraulic resistance decreases with increase of relative submergence degree, reducing slowly to a constant too.

通过水槽试验对Y型加糙体阻力特性进行了深入研究。研究结果表明：其糙率具有一个较大的调整范围，且随着加糙间距的增加水力阻力减小，减小的幅度越来越小，最后基本不变；雷诺数在3 500左右水流进入阻力平方区，进入阻力平方区后，随着相对淹没度的增大水力阻力减小，最后达一定值。

Native element: Any of the 19 chemical elements that occur as minerals and are found in nature uncombined with other elements.

自然元素：以自然状态存在于矿物中，不与其它元素结合的十九种化学元素。

One common strategy is to preallocate a block of raw memory to hold unconstructed objects. When new elements are created, they could be constructed in one of these preallocated objects. When elements are freed, we'd put them back in the block of preallocated objects rather than actually returning memory to the system.

一个通用策略是预先分配一场原始内存来保存未构造的对象，创建新元素的时候，可以在一个预先分配的对象中构造；释放元素的时候，将它们放回预先分配对象的块中，而不是将内存实际返还给系统。
