I. d. Bernoulli random variables. First, we can get the upper bound with order from Chebyshev inequality. Second, a better upper bound was gotten with the new inequalities, which can fasten the convergence rate.

并对服从两点分布的独立随机变量X1，X2，…，X进行研究，首先利用Chebyshev不等式得到随机变量偏离方差ES的上界，但它只有阶的收敛速度，然后利用新的不等式得到一个新的上界，它有更快的收敛速度，这在探讨收敛速度时有着重要的理论意义。

First, it was to obtain two binary images from segmenting image by two thresholds. Second, erosion, opening and closing were done to the two images according to some knowledge of the shape and location of the objects in the image that we have already known. Last, the edge information from the image segmented by a high threshold was put into the image segmented by a low threshold. It is the way to segment and discern circular objects accurately from the complex image and can greatly improve the accuracy rate of discerning.

首先分别根据两个阈值进行分割得到两幅二值图像，然后根据目标是圆形以及其大致位置等先验知识分别对两幅图进行腐蚀，开启，闭合等数学形态学运算，将高阈值分割得到的图像中的边界信息叠加到低阈值分割得到的图像中，实现对复杂背景图像中圆形物体的准确分割与提取，解决了复杂背景图像中物体识别率低的问题。

After implementing strategies, including re-screening participation subjects, changes in care procedures for newborns, reinforcement in advertisement, using individual telephone contact, increase the frequency of invitation, and adjustment the holding time and frequency of postpartum class, the participation rate increased from 28.9% to 82.4% at the first time of evaluation, to 100% at the second time of evaluation.

经实施重新评估参加的对象、更改新生儿照顾方式、加强海报宣传、电话个别通知、增加邀请次数及调整妈妈教室举办时间与频率等解决办法后，参与率已由实施前的28.9%提升至第一次评值之82.4%；第二次评值之100%，达本专案目的。

Typical bands were used to analyze relation with ecotypes and characters of fruits, indicating that there was no relation between typical bands and ecotypes, but some extent relation between bands and characters of fruits existed. If all cultivars were divided into freestone and clingstone, melting and nonmelting, both freestone (ratio shared total survey, 41/56=73.2%) and clingstone (ratio shared total survey, 33/79=41.8%) appeared in the loci of S_(167)-1050 bp linked marker raised by Warburton et al. It was apparently not strong linkage between the marker and the character, and exchange rate of genes was high. If combinations of S_(167)-850bp and S_(167)-1050bp or S_(167)-850bp and S_(167)-1400bp were used to distinguish characters of fruits, 6 freestone accessions without clingstone ones and 6 melting accessions without nonmelting ones displayed in the first combination of markers, 20 clingstone accessions and 2 semi-freestone ones without freestone ones appeared in the second combination of markers.

通过典型带对不同生态型、果实性状为类别进行分析，结果未发现有与生态型相吻合的特征带出现，而将供试所有品种按离核、粘核和溶质、不溶质划分归类，供试品种在Warburton等得到S_(167)-1050 bp处粘离核分子标记，出现既有离核(占供试离核41／56=73.2％)，又有粘核(占供试粘核33／79=41.8％)，可见此连锁标记连锁性不强，发生交换的机率较高，而S_(167)-850bp带和S_(167)-1050bp带同时出现时，该组包含6个离核，无粘核品种；6个溶质，而无不溶质。S_(167)-850bp和S_(167)-1400bp同时出现时，包含20个粘核品种和2个半离核品种。
