Identification for a class of distributed parameter systems

This paper discusses the identification for the distributed parameter system of gas reservoirs with het erogeneous carbonate matrices. Based on the relationship between the ad hoc function and the geological feature, we set up a general model with double porous structure, clarify its effect and significance, and present a series of results of sys tem identifications, including the basic content and methods, stabilizing functional and parameter identifiability etc. Us ing the perturbation of spectra of self-adjoint operators, the identifiability of the porosities and the ad hoc coefficient is demonstrated for the general structure model. This project indicates that the identification of a distributed parameter sys tem involves parameters, boundary position and structure.

动物常见疾病在不同年龄的分布特征

对1351例各类动物常见疾病的临床表现率在13个不同年龄组的分布特征进行了探讨,得出了年龄与疾病发生的一些内在变化规律。结果表明1岁以内(尤其是1月龄以内)是动物各种临床疾病最常发的年龄,占各年龄组病例的35.68％;其次是3～4岁的动物,发病率高达22.67％。在不同的年龄阶段所发生的疾病有所不同,但最常见的疾病是胃肠道疾病,前三位的依次是反刍动物的前胃驰缓(18.21％),各种动物感冒(13.84％)和反刍动物瘤胃积食(10.73％);而不孕症是常见的产科病(3.65％),它占各种母畜产科疾病的34.75％,且多见于3岁的动物。

Sources of cumulus expansion enabling factor (CEEF) in porcine follicles

It was shown that expansion of porcine cumulus did not depend on oocyte-secreted factor(s), and it is therefore presumed that porcine CEEF may not be produced exclusively by the oocyte. In this experiment, we used mouse oocytectomized complexes (OOX), which were incapable of CEEF production, to assess the secretion of CEEF by evacuated zona, oocytes of different quality and somatic cells in the porcine follicles. The results showed that: (ⅰ) Evacuated zonae from both porcine and mouse oocytes did not produce CEEF. (ⅱ) Porcine oocytes of A, B and C types from 3—6 mm follicles were not significantly different in both production and activity of CEEF. (ⅲ) Both porcine OOX from 3—6 mm follicles and granulose cells from < 1 mm follicles secreted CEEF in a large quantity, independent of gonadotropins; mural granulose cells from 3—6 mm follicles, however, produced neglectable amount of CEEF. (ⅳ) The follicular fluid from 3—6 mm porcine follicles contained CEEF activity that was concentration-dependent, and thus it enabled cumulus expansion in 60% mouse OOX when used at 10% of concentration, but the expansion rate of mouse OOX decreased to 9% when the concentration was increased to 50%. (ⅴ) Mouse OOX cultured in porcine CEEF-containing M199 expanded only in the presence of gonadotropins, suggesting that the activity of porcine CEEF is hormone-dependent.
