可变因素

isolates recovered from tuberculosis patients of rual morth Jiangsu province with variable-number tandem-repeatgenotyping, and analyze factors related to the dominant VNTR genotype.

目的运用可变数目串联重复分型方法研究农村结核病研究现场的结核分杆菌分离株的分子特征，分析与VNTR优势基因型相关的因素。

Using the distortion-compensated roentgen analysis method, disc height, dorsoentral displacement, and lordosis were measured in 212 unfused segments from 62 patients, on digitized standing radiographs taken before fusion surgery and after a mean follow-up of 7.5 years (range, 4-11 years).

在标准数字化X光片上，比较术前和术后平均7.5年（4－11年）后62个病人212个未融合节段的椎间盘高度、椎体滑脱及脊柱前凸的情况，可变的影响因素如年齡、随访时间的长度、融合水平、融合节段数、融合节段上下方向和手术前后椎管的改变，用重复测量模型进行分析。

When you add into that the changeable conditions, and also the fact we were running without power steering today, it could have been a tricky day for Fairuz but he didn't put a foot wrong so well done to him and a big thank you.

&当加上这些可变的因素，同时今天我们的测试没有使用动力方向盘，对法兹来说是不容易处理的，但是他没有一点的问题，做的非常好，非常感谢他&

In summary, various key experimental conditions in electron acoustic imaging of ferroelectric domains were systematically studied. The optimum experimental conditions to obtain EAI of domains with good quality and the factors important to image analysis have been presented. The piezoelectric vibrator model and calculation of motion equation are helpful for explaining the imaging mechanism and related experimental phenomena. The sample holder with variable electric field was designed. The domain movement of BaTiO〓 ceramics and crystal under lateral and longitudinal applied electric field and domain movement of PMN-PT crystal under longitudinal poling electric field were observed. The application of SEAM on revealing of ferroelastic domains, imaging of residual stress distribution in ceramics coatings and around the pores on the surface of ferroelectric ceramic composite have been reported respectively. All these works enriched the study of electron acoustic imaging and extended the application of SEAM in the characterization of materials.

综上所述，本文系统地研究了各项关键实验条件对电畴电声成像的影响，指出了获得最佳畴结构电声像的条件和成像分析中应当考虑的各种影响因素；提出了解释电畴电声成像的压电振子模型，在此基础上推导并求解了压电振子运动方程，并对一些实验现象作出了解释；成功地设计了可变电场的样品台，观察了BaTiO〓陶瓷和晶体在横向电场作用下的畴运动，PMN-PT晶体在纵向极化电场作用下的畴运动；探索了电声显微镜在铁弹畴成像，陶瓷涂层应力观察，陶瓷自然表面气孔周围应力成像的应用，这些研究，丰富了电声成像的学术内涵，拓展了电声显微镜的应用领域。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
