| 1. | A frequency distribution shows the number of observations from the data set that fall into each of the classes .
频率分布反映出落入每一组的观察值个数。 |
| 2. | Statistical probability is usually based on an infinite number of observation
统计概率通常基于大样本观测。 |
| 3. | In the exercises you will be asked to make a number of observations and answer questions
在这个实习中，将会要求做多次的观察与问答。 |
| 4. | Probability the chance that a given event will occur , or that over a series of observations a particular kind of observation will occur regularly as a given proportion of the total number of observations
概率：指某给定事件即将发生的机率，或经过一系列观察后，某些特定的观察规律性出现的可能性。 |
| 5. | How the proficiency of estimation is affected is analyzed . how to choose optimal number of observations and how to determine the order of model are also studied and practical method is presented for each
讨论分析了影响估计精度的因素，也对最佳的数据数量和模型阶数的确定方法进行了研究，分别提出了一种行之有效的方法。 |
| 6. | When the number of observation is small the order index for initial selection should be unit weighted rms ; the weight should be take into account ; the unit weighted rms correlated to gross error determination standard should adopt empirical value
当观测值较少时，初选之前观测值的排序指标宜采用单位权中误差进行；粗差的判别和复选之前的排序都应该考虑权重的影响；判别准则中的单位权中误差应该采用先验值。 |
| 7. | Method the large defects of articular cartilage were repaired with grafts of freeze - stored and fresh chondrocytes cultured on fascia , periosteum and articular cartilage , which were evaluated by a number of observation methods
方法用冻存和新鲜的异体筋膜上培养的软骨细胞、骨膜和关节软骨移植修复大面积关节软骨缺损，通过大体标本、光学显微镜、扫描和透射电镜、放射自显影、微量元素和柱层析氨基酸定量测定、一氧化氮含量测定等多种观察方法进行评价。 |
| 8. | The quad method can detect n - m - 1 gross errors in theory , if there exist , ( n is the number of observations , m is the number of unknown parameters ) and its breakdown point is much high , so its application prospect is very broad in many fields . the quad method program is preliminarily designed with matlab language for its powerful matrix function , simple language and friendly interface
拟准检定法是一种高崩溃污染率的数据检测方法，理论上，能探测到n - m - 1个粗差(如果存在粗差) ( n为观测个数， m为待估参数个数) ，因此该方法在许多领域有比较广阔的应用前景。 |
| 9. | There are a number of observations that can be simplified into three broad categories : corticosteroids can induce physical and mechanical changes in the microstructure of the trabecular meshwork ; cause an increase in the deposition of substances in the trabecular meshwork , thereby causing decreased outflow facility ; and inhibit proteases and trabecular meshwork endothelial cell phagocytosis causing a decrease in the breakdown of substances in the trabecular meshwork
这方面的研究很多，研究结果大致可以分为几类：类固醇能够改变小梁网显微结构的生理和机械性改变；能够增加小梁网细胞外基质的沉积，从而降低房水流畅系数；能够抑制蛋白酶和小梁网内皮细胞吞噬功能，从而减少小梁网细胞外基质的降解。 |
