组距

The problem of the error of calculation formula calculating the variance of grouping data within distances in statistics was put forward,and the concrete forms of correcting formula were given by the theorem of addition and the variance of even distribution.

提出统计学中的组距分组资料方差和标准差计算公式误差问题，由方差的加法定理和均匀分布方差给出分组资料方差计算和标准差计算的修正公式具体形式，并就均匀分布数列和正态分布数列组内方差平均数进行了讨论

Results showed the training effect did not reach the significant difference. However, by using SPSS for windows 10.0 software mix design two factor trends analysis at pretest, mid-test and posttest stage. Results showed the long distance group performed better than the three-point line training group in term of training effect. Indeed, the three-point line group surpassed than the control group.

结果：1105名受检青年女性中，视力正常组与近视眼组的瞳距均值分别为59.27，59.35mm，两组瞳距比较经统计学处理无差异性存在；眼球突出度均值视力正常组为15.49mm，近视眼组为15.76mm；视力正常眼，轻度、中度、高度近视眼各组人群测定眼球突出度经方差分析比较有显著性差异（F=6.108，P.01），4组人群眼球突出度经LSD处理后两两比较：视力正常眼与中、高度近视眼，高度近视眼与轻、中度近视眼等4组之间均有显著性差异（P.05）；各组眼球突出度左、右眼间比较，差异均无显著性。

The results of the rule of law with ordinary methylation by formaldehyde Veratryl three groups the average weight of 2.5609g, the average yield was 91.31%, the melting point of the three groups were 42.4 ~ 44.8 ℃, 41.5 ~ 45.2 ℃, 41.7 ~ 44.3 ℃, from the results of we can see that the three groups of the melt from the melting point greater than that which the product of the by-product of the detection of the melting point have a certain impact; and the legal system with microwave radiation by an average of Veratrum aldehyde quality 1.4016g, the average yield was 93.23 %, melting point of the three groups were 41.8 ~ 43.2 ℃, 41.3 ~ 42.6 ℃, 41.6 ~ 43.5 ℃, melting away from the three groups as compared with ordinary methods of measuring the melt-out from the small.

结果 用普通甲基化法制出来的三组藜芦醛平均质量为2.5609g，平均产率为91.31％，三组的熔点分别为42.4～44.8℃，41.5～45.2℃，41.7～44.3℃，从结果可以看出，三组熔点的熔距都比较大，证明产物当中的副产物对熔点的检测有一定的影响；而用微波辐射法制出来的藜芦醛平均质量为1.4016g，平均产率为93.23％，三组熔点分别为41.8～43.2℃，41.3～42.6℃，41.6～43.5℃，三组熔距较普通方法测出来的熔距小。

Results There was a downtrend in weight of dams on GD20 as the DBTD exposure dose increased. The weight of dam's utero significantly decreased in 30 mg/kg group. A significant decrease in fetal weights was observed in all DBTD groups, and fetal sizes in 20, 30 mg/kg groups. Exposure to DBTD from GD 12-19 resulted in a distinct increase in normalized anogenital distances in female fetuses, but no effects were seen in male ones.

结果 妊娠20d时，孕鼠体重随DBTD剂量升高呈下降趋势，但与对照组比较，差异无统计学意义，30mg/kg组孕鼠子宫重量显著降低；所有DBTD染毒组雄性、雌性胎鼠体重均显著降低，20、30m/kg组胎鼠体长显著降低；所有DBTB染毒组雌性胎鼠肛门距生殖器的标化距离显著增长，而雄性胎鼠无显著变化。

In group A, the medial antebrachial cutaneous nerve was cut 5 mm away from its origin and its proximal end was anastomozed end-to-end to the distal end of musculocutaneous nerve. In group B, the musculocutaneous nerve was cut 5 mm away from its nerve entry point and the proximal end of medial antebrachial cutaneous nerve were anastomozed end-to-end to the distal end of musculocutaneous nerve. In group C, medial antebrachial cutaneous nerve and musculocutaneous nerve were cut, without further anastomosis.

每组大鼠左上肢制备实验模型，右上肢为正常对照，不作任何处理。A组：于距前臂内侧皮神经起点5 mm 处切断该神经，将其近端与切断的肌皮神经远端行无张力端端吻合；B 组：于距肌皮神经入肌点5 mm 处切断该神经，将其远端与切断的前臂内侧皮神经近端行无张力的端端吻合；C 组：切断肌皮神经和前臂内侧皮神经后不予吻合，形成肱二头肌失神经支配模型。

Every indicatrion has statistics difference after six mouthstreatment of Two rattan mixture which include body function, activity index number of pathogenetic condition, total swelling arthrosis, total self-assessment, rachialgia, rachiodynia rhachitis, activity of thoracic skeleton, schober, distance between fingers and ground, left flection of antisternum, right flection of antisternum, antisternum hypsokinesis, distance between head and wall, ESR, C reactive protein: every indicatrion has statistics difference after the treatment of Sulfasalazine except the indicatrion of distance between head and wall.
