Paul Erds once posed the following problem about real line R: is it true that, for every infinite set X, there is a closed set E with positive lebesgue measure such that E doesn't contain any subset similar to X (I.e., there is no subset of E, which is a linear homeomorphic image of X). In 1984, K. J. Falconer proved the following: for a decreasing sequence of positive numbers {xn} such that \%lim\%xn=0 and \%lim\%(xn+1)/=1, Erds problem has a partial positive answer.

叶盛 Paul Erds曾提出如下关于实直线R的问题：是否对R的每一个无限子集X，都存在一个具有正测度的闭子集E，使得E的任何子集都不相似于X(E的任何子集都不与X线性同胚)。1984年，Falconer证明了如下结论：对于一个满足limxn=0和lim(xn+1)/=1的单调递减的正实数列{x n}，Erds问题有一个部分肯定的解答。

By means of traditional criterions of generalized integral's convergence and divergence, this paper, from the analysis of integrated function's nature, discovers a series of new criterions, which are briefer and more suitable: on the aspect of generalized integral for functions of a single variable, through the investigation of integrated function, together with the inner relationship between positive series and generalized integral in infinite interval under the condition of positive function, it gives several criterions of generalized integral's convergence and divergence, which are similar to positive series' criterions of convergence and divergence.

本文从分析被积函数本身所具的性质出发，借助传统的广义积分敛散性判别方法，发现1系列更简捷适用的新判别方法：单变量函数广义积分方面，通过考察被积函数，结合正项级数与正函数情形下无穷区间上广义积分的内在联系，给出了几个与正项级数敛散性判别法相类似的广义积分敛散性判别方法；多变量函数广义积分方面，着重讨论了广义2重积分和广义3重积分，结合被积函数的特点，运用比较判别法和柯西判别法，本文给出了判别广义2重积分收敛的1种新方法。

The results showed that typical FMD clinical signs produced in cattle inoculated intradermally with pathogenic FMDV after 48 h. The 3ABC antibody produced in these cattle were detected to be suspicious on the 3rd day, 3ABC antibody in the 1/4 cattle were positive on the 5th day, and the 4/4 were positive on the 8th day post virus inoculation; In 10 co-housed cattle (breeded with artificially infected pigs and sheep separately), no 3ABC antibody were detected on the 7th day and percent of positive 3ABC antibody was only 30%(3/10) on the 15th dpi (4/10 had clinical symptom).

实验表明，4头牛在舌面接种感染FMDV 48h后全数发病，第3天即出现可疑的3ABC抗体，第5天检测到阳性的3ABC抗体，至第8天3ABC抗体全部为阳性；10头同居牛（分别与接种感染猪和羊同居）在同居第7天时未检出3ABC抗体，在同居第15天时，3ABC抗体阳性率仅为30%；肌肉接种病毒羊3ABC抗体产生时间与接种病毒牛一致。

Zhan has determined the maximum and minimum numbers of positive entries of imprimitive irreducible nonnegative matrices with a given imprimitivity index. In this paper, we prove that if a positive integer is between the maximum and minimum numbers, then there exists an irreducible nonnegative matrix A with the given imprimitivity index and with the given number of positive entries.

非负矩阵是矩阵论中研究比较活跃的领域，不可约非负矩阵是比较重要的非负矩阵，本文分两部分，一部分主要在詹兴致教授的研究基础上研究了给定非本原性指标的不可约非负矩阵中非零元个数的连续性，肯定地回答了詹兴致提出的一个自然的问题。

Result Among the 1st principal components, the positive weight value of chest diameter was greatest and it was the eigenvector with greatest influence on the 1st principal components. Among the 2nd principal components, the character loading value of leaf-lobed width and the positive weight values of angle between leafstalk and its branch and leaf-shape index were greater. Among the 3rd principal components, the positive weight values of leaf number, branch length, branch thickness and developed degree of crown size of 1 year old branches were greater.

Results In 50 patients with toxoplasmal lymphadenitis, 16 patients were positive for Toxoplasma antigen. 5-HT and 5-HTI AR positive markers between the positive and negative groups were similar, which were distributed in the T lymphocytes in cortex of lymph gland and the B lymphocytes and macrophages in lymph follicle germinal center.

Immunohistochemical localization of inhibin α-subunit in normal mature rats was carried out by using Strept Avidin-Biotin-Peroxidase Complex .The results showed that there was positive immunoreactivity of the McAb to inhibinα-subunit in heart ,kidney , spleen , lymph ,adrenal gland and pancreas cells. It indicated that inhibinα-subunit existed in the above tissues , But no positive sites were seen in hypothalamus, pituitary, lung and liver, that means they have no inhibinα-subunit. Compared with the ovariectomized rats, the hypothalamus and pituitary of the rats injected with inhibin-α fragment（1～32）showed an positive reaction, suggesting that inhibin α-subunit could pass through the blood-brain barrier .

用链霉亲和素-生物素-过氧化物酶(Strept Avidin-Biotin-Peroxidase Complex， SABC)免疫组织化学方法，以抑制素α亚基单克隆抗体对正常雌性性成熟大鼠各组织的抑制素α亚基进行定位观察，结果显示：⑴大鼠心脏、肾、脾、淋巴、肾上腺、胰腺均呈阳性反应，表明存在抑制素α亚基；下丘脑、垂体、肝脏和肺组织呈阴性反应，表明其不存在抑制素α亚基；⑵与去卵巢大鼠相比，外源注射抑制素α（1～32）片段的大鼠其下丘脑和垂体出现阳性反应，说明抑制素α亚基能通过血脑屏障。
