Two types of low carbon weathering steel with different Mn content were produced in vacuum induction furnace.

在真空感应炉冶炼了2炉不同锰质量分数的低碳耐候钢，利用热模拟机和金相显微镜分析了其组织特征和相变规律，并通过室温拉伸、冲击实验且结合断口分析表征了实验钢的强韧性。

In most examination paper, the differences in difficulty, reliability and the distribution of score is ineluctable.

在大多数考试中，不同试题之间在难度、信度、分数分布方面的差别是很难完全避免的。

Scores can also be expressed as a finite or infinite decimal recurring decimal.

无限循环小数可以转化为分数。。。

And brilliant achievements have been made in the teaching of the chemistry contest, which has attracted the worlds attention. On the other hand, there are some problems with the chemistry contest which can not be overlooked, like training inflexibly by stuffing exercises and grade-oriented practices.

化学竞赛一方面已经取得世界瞩目的辉煌成绩，为高校选拔了大批优秀学生；另一方面，也存在题海战术、机械训练、片面追求分数与名次等诸多不容忽视的问题。

The conclusions can be drawn through numerical simulation: The hydrate-forming region becomes small with increasing circulation rate and inhibiter concentration, and it is possible to make the hydrate-forming region away from sea floor by increasing circulation rate and inhibiter concentration, thus preventing blowout preventer lines from hydrate plugging; the decrease in gas volume fraction in the annulus due to hydrate formation reduces pit gain, which can delay the detection of well kick; the possibility of hydrate presence at a relatively low gas production rate is much greater than that at a relatively higher production rate; the bottom hole pressure is affected little by hydrate phase transition, and it is allowable not to consider hydrate phase transition when the bottom hole pressure is calculated; shut-in casing pressure cann't truly reflect gas kick due to hydrate formation and the situation is getting worse with time

模拟计算结果表明：溢流期间，天然气水合物的生成区域会随着循环流量的增大或抑制剂浓度的提高而减小，可通过增大流量和抑制剂浓度使水合物的生成区域脱离海底，减小防喷器管线被堵塞的危险；水合物的生成使环空中气体体积分数降低，泥浆池增量减小，给溢流检测带来延迟；当检测到有气侵发生时，水合物藏分解速率比较小时，井筒中生成水合物的可能性要比分解速率大的情况下更为严重；水合物相变对井底压力的影响较小，在工程中计算井底压力时可以忽略；由于天然气水合物的生成使得关井套压值不能真实反应气侵情况，而且随着时间的增加情况会更加严重。

After anesthesia induction, INO (mass fraction , 20×10 -6 ), added to the gas mixture, was given to the anim...

麻醉诱导完成后，将INO(质量分数为 2 0× 10 -6)添加到混合气体中，给猪吸入直至实验结束。

John was on the inside track for the position because he had the best marks.

约翰最有可能获得这个职位，因为他分数最高。

Score of each person is an integer.

人的分数都是整数。

The transfer matrix and diffractive integral formula in frequency domain were acquired by rotating the input and output optical field π/2 in the phase space. Accordingly the fractional Fourier transforms of a first-order optical system in frequency domain were also obtained.

通过将输入输出光场在相空间中作π/2角旋转，得到了一阶光学系统在频域的传输矩阵和衍射积分公式，进而得到了一阶光学系统在频域的分数傅里叶表示。

The basical understand of fraction is based on and extended from integral number .

对分数的初步认识是在整数基础上进行的，是数的概念的一次扩展。
