查询词典 observational error

Design of Experiments and Quasi-Experiments Statistical designs for the estimation of the effects of treatments in both controlled experiments and observational studies.

实验和准实验设计：包括：实验和准实验设计：和准实验设计观察性试验和控制性试验中的处理效果估计的统计设计。

The results show that population change is the main cause for cultivated land reduction in Suzhou City since the reform and opening. In addition, changes of the urbanization rate and proportion of the tertiary-industry added value to regional GDP of the area also play an important role in the cultivated land reduction. In the scope of observational data, the relationship between the prosperous level and the cultivated land area is similar to the Environmental Kuznets Curve, and Suzhou City is at the early stage of the curve, that is, the period of prominent contradictions.

结果表明：在诸多影响因素中，人口数量的变化是引起改革开放以来苏州市耕地面积减少的主要因素；而第三产业增加值占地区生产总值比重和城市化率的变化对耕地面积的减少也发挥着重要作用；在观测数据范围内，富裕度和耕地面积之间存在类似环境Kuznets曲线，并且苏州市正处于该曲线的前期阶段，属于矛盾的凸显期。

And the observational analysis and modelling study have focus on tropical SSTA in relation to Asian winter monsoon and low--latitude Pacific trade wind.

观测分析和数值模拟还注重于分析热带海表温度异常对亚洲冬季风系统和热带太平洋信风的影响。

Limitations of this study include observational design, use of data that had already been collected, missing data on tumor size for more than half of cases, lack of data on chemotherapy, and possible residual confounding by unmeasured predictors.

研究限制包括属於观察性设计，使用现有的资料，半数以上案例缺乏肿瘤大小的资料，缺乏化疗的资料，可能有其他未探讨的可能干扰因素。

Deep\|hole Broad\|band Strain\|Seismograph can greatly upheave the observational band of traditional inertia pendulum seismometer, and the earthquake displacement enlargement can be greatly magnified to thousand times.

发展"深井宽频钻孔应变地震仪"可将惯性摆地震仪的观测频宽提高数十倍，地动位移的放大倍率提高数十到数千倍。

The method does not depend on strict local parameters and precise instruments, while the observational principle is relatively simple. An experimental observation was carried out with a simple telescope with large field of view at Xinglong station of NAOC at the end of 2007. The atmospheric refraction from the zenith distance of 44.8 degree to 87.5 degree is gotten by the differential method, which proves the feasibility of the method tentatively.

该方法不依赖于严格的地方参数和复杂精密的观测仪器，并且观测原理相对简单。2007年底，利用一台简易的大视场望远镜在兴隆观测站进行了试验观测，根据较差方法实测得到真天顶距44.8°至87.5°的大气折射值，初步证明了大气折射较差测量方法的可行性。

Only keep to the science,emphasize the whole observation can we gain the whole ,general and artistic impression to ground well for the future correct drawing,can we train our acuminous observational ability to help us to refine a pair of artist eyes.

只有遵循一定的科学性，强调整体性的观察，才能得到完整、概括、艺术的总体印象，为正确的画打下良好的基础，才能培养出敏锐的观察力，炼就一双&画家&的眼睛。

Methods 256 cases with chronic apicitis were divided randomly into the observational group （use Periocur as intracanal medicament） and the contol group （use formocresol as intracanal medicament）,and investigated the clinical effect after one week.

Objective To evaluate and compare the efficacy of Periocur or formocresol as intracanal medicament in root canal therapy of chronic teeth apicitis.Methods 256 cases with chronic apicitis were divided randomly into the observational group （use Periocur as intracanal medicament） and the contol group （use formocresol as intracanal medicament）,and investigated the clinical effect after one week.

目的 观察Periocur消炎液用于根管消毒的临床疗效方法选择256例慢性根尖周炎病例，随机分成观察组（Periocur消炎液组）130例、对照组126例，观察根管封药1周后的临床疗效。

That's what makes this mod unique.

这也正是这个MOD独特。

I now feel furious and want to do something.
