About 12.9%-27% of applied amount of 14C-metsulfuron-methyl was mineralize d to 14CO2 through opening 14C-triazine ring in soils tested after 180 days of the incubation.

4在整个培养试验期间(180d)，14C-甲磺隆在7种土壤中通过三嗪杂环开环矿化为14CO2的量约占引入量的12.9-27.0%，其在碱性土壤中更难被矿化为14CO2。

The Neumann boundary value prob-lem is firstly reduced into the equivalent natural boundary integral equation withthe kernel possessing 2nd-order singularity,and then the corresponding variationalproblem on the boundary is obtained.By applying Quak trigonometric wavelet basisBjsee(1.2.3as boundary elements and the method of expanding kernel functionto its Galerkin discretization,we obtain simple computational formulae of the en-tries in the stiffness matrix.

首先，我们将Neumann边值问题归化为等价的带有2阶强奇性核的自然边界积分方程，然后化为边界上相应的变分形式，以Hermite插值Quak三角小波基Bj见(1.2.3作为边界元并利用积分核函数展开法将其离散，得到了十分简单的刚度矩阵系数的计算公式，而且刚度矩阵具有十分简单的形式，它是分块循环对角阵。

Hence, initializing a pointer to NULL is equivalent to initializing it to 0

因此，把指针初始化为 NULL 等效于初始化为 0 值

After the completion of DAE with removal of singular points, a DAE system may be transformed into ordinary differential equations on manifolds; it is also possible to transform DAE to a singular perturbed system as ODE.

通过将DAE完备化并去掉奇异部分，可以把DAE化为流形上的常微系统；也可以将DAE化为奇异摄动系统而得到ODE。

Take complicated problem oversimplifies and abstract problem pictorialize as base, Take software project manages process visualization and controllabled as basic goal.

The characteristic vector of the real symmetric matrix should be found out, which is orthogonalized and normalized to a standard orthogonal base and is used as row vector to construct the transformation matrix P, so the P~(-1)AP can be made into diagonal matrix.

实对称矩阵A经相似变换P-1AP可化为对角矩阵，在x =Py 下，不一定能化A的二次型为标准型；应寻求对称矩阵A的特征向量，将其正交化并单位化作为标准正交基，作为列向量构造变换矩阵P，可使P-1AP=Λ为对角阵，在x =Py 下，要将二次型化为标准型，且二次项系数即为对角阵Λ主对角线上元素。

Suddenly the door of the room flew open and the draught of air caught up the little dancer, she fluttered like a sylph right into the stove by the side of the tin soldier, and was instantly in flames and was gone.

突然间房门打开了，气流卷起小舞蹈家，她就像风精一样，飞向火炉，飞到锡兵的身边去，化为火焰，立刻就不见了。这时锡兵已经化为一个锡块。

Results show that C_(2)AS in high-alumina cement with CACA_(2)C_(2)AS system can be transformed into the Q phase when adding MgO and abundant CaO after calcined at high temperature.

结果表明：高铝水泥系统中的C2AS，在加入MgO和系统补钙的条件下，经过高温煅烧能够转化为Q相，高铝水泥系统CA 二铝酸一钙(CA2) C2AS变化为Q相CA C12A7.Q相CA C12A7的烧成温度为1 260~1 300 ℃，保温时间为30~60 min。

The intermetallic compounds are coarsened into nubbly Cu6 Sn5 phase by adding excessive Cu into Sn-Cu solder alloy. For Sn-9Zn-xCu solder alloys, the long needle-like Zn rich phase which is the mainly existing form of Zn in Sn-Zn solders is transformed into Cu5 Zn8 phase and fine Zn rich phase by the addition of 2% Cu, while CuZn phase and Cu6 Sn5 phase are formed in Sn-9Zn-10Cu bulk alloy. When soldering within short time under 260℃, the ripening and growth of IMC at Sn-xCu/Cu interface are accelerated with increasing Cu content in Sn-Cu solders.

结果表明，当Sn-Cu钎料中Cu的含量为2%时，基体中IMC粗化为块状的Cu6Sn8相；对于Sn-9Zn-xCu钎料合金，2%Cu元素的加入使得Sn-9Zn基体中长针状的富Zn相转化为Cu5Zn8相以及细小的富Zn相，而当Cu含量达到10％时，钎料基体中的IMC为CuZn相与Cu6Sn5相。
