变为

Over the past few days, the rash has become pustular with notable crusting.

持续数天后，斑疹变为带明显痂壳的脓庖。

When treated with PYM ,mutation rates of ear length and tassel branch number were high, which were 4.81% and 4.77%. Mutagenic effect of PYM was worse than that of EMS and NaNa-Benzoyl.

PYM处理以穗长和雄穗分枝数的突变为高，4.81％、4.77％，其诱变效果没EMS和NaNs一苯甲酸胺处理好。3。

However, the cell wall cultured at high concentration of Cu2+(10～200 mg/L) was clearly thickened and became multiple layers, and the pigment decreased and the pyrenoid became one or disappeared. Low concentration of Cu2+(0.01 mg/L, 0.1 mg/L) did not affect the growth of Chlorococcum sp., but the growth became slow and even negative beyond the concentration of 0.1 mg/L.

与对照BG11培养的绿球藻比较，0.01～1 mg/L Cu2+浓度下培养的绿球藻，细胞壁无明显增厚，色素没有多大变化，但蛋白核由一个变为多个；而在高浓度(10～200 mg/L Cu2+)下，细胞壁明显增厚为多层，色素减少，蛋白核减少并回复到1个或消失。

Theseshistose pyrites being composed principally of coal, flint, alumina, andsulphuret of iron–the latter in excess–it was necessary to separate thesulphuret of iron, and transform it into sulphate as rapidly as possible.

这些黄铁矿石的主要成分是炭、火石、矾土和硫化铁，其中硫化铁的含量过多，必须使它分离，尽快地把它变为硫酸盐。

In the model, the non-sensitive loss function was replaced by quadratic loss function and the inequality constraints were replaced by equality constraints.

在该模型中，用二次损失函数取代支持向量机中的不敏感损失函数，将不等式约束条件变为等式约束，从而将二次规划问题转换为线性方程组的求解，并提出对核函数的盯参数进行动态选取。

The non-sensitive loss function is replaced by quadratic loss function and the inequality constraints are replaced by equality constraints. Consequently, quadratic programming problem is simplified as the problem of solving linear equation groups.

用二次损失函数取代支持向量机中的不敏感损失函数，将不等式约束条件变为等式约束，从而将二次规划问题转变为线性方程组的求解。

The quadrivalent was made of the normal 11 chromosome, the normal 18 chromosome, the translocated 11; 18 chromosome and the translocated 18; 11 chromosome.

精母细胞中SC分析，在早粗线期、中粗线期和晚粗线期精母细胞中，均发现22个常染色体SC和一个XY-二价体，即23个二价体；未发现22个二价体和一个单价体细胞，说明这条rob（21q；21q）染色体的两个臂完全配对形成发夹结构，形态上与正常SC一样，但与正常21号SC相比，其相对长度变短，由正常的1.5±0.1变为1.25±0.05。

She lived on the Quai des Celestins, at the corner of this ancient street of the Petit-Musc which afforded her the opportunity of changing her evil repute into good odor.

她当时住在则肋斯定河沿，在那条古老的小麝香街转角的地方，那条街已力所能及地把它的臭名声变为香气。

It had been difficult and tiring to quantitate a small amount of DNA until the invention of real time PCR technique, which is as easy as regular PCR.

少量的DNA 序列的准确定量曾经是一件很难很累的事情，不过real timePCR 的出现把它变为和普通PCR 差不多一样容易。

When they do so, they usually transform one kind of quark into another, yielding a rich harvest of new types of particles

当它们这样做时，经常会使一种夸克变为另一种夸克同时产生大量的新型粒子。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
