Based on works above all, the thesis compares results of positive analysis with what is going on in real markets, proceeds to verify the results of positive analysis, the thesis brings forward some advice in order to reform and perfect the China"s agricultural commodity futures markets.The first two chapters in this article investigates the unbiasedness hypothesis of futures prices in China"s agricultural commodity futures markets.

第二章详细介绍了协整技术和误差修正机制，利用该技术分析了距离最后交易日一月、二月、三月、四月、五月和六月期的大豆和小麦期货价格与现货价格之间的协整关系，发现四月期以内的大豆和二月期以内的小麦期货价格是对现货价格的无偏预测，而五月、六月期的大豆和三月期的小麦期货价格不是现货价格的无偏预测，四月、五月、六月期的小麦期货价格与相应的现货价格不存在协整关系。

The two kinds of clefts are: unoperated isolate cleft palate and unilateral cleft lip and palate with lip only operated. Considering the effect of age on the results, The samples were divided into two age groups: mixed dentition stage and adult permanent dentition stage. The cases of these two groups of unoperated isolate cleft palate patients are 16 and 25 respectively, and those of unilateral cleft lip and palate with lip only operated are 15 all.

考虑到青春期生长发育对研究结果的影响，又分别将这两种类型的患者按年龄分成混合牙列期和成人恒牙列期两个年龄段，与相应年龄段的单纯腭裂术后患者、单侧完全性唇腭裂术后患者及非唇腭裂正常者进行比较，单纯腭裂未手术的患者混合牙列期和成人恒牙列期例数分别为16例和25例，单侧完全性唇腭裂仅修复唇裂患者混合牙列期和成人恒牙列期例数均为15例。

New data reveal that the age of the so-called Gigantopteris Coal Series indifferent places of South China is not exactly the same and ranges from the late LowerPermian to the close of the epoch,while several elements of the Gigantopteris-Flora,such as Gigantopteris,Pecopteris,Annularia,Lobatannularia and Paracalamites mays...

新的资料证实，这一含煤地层的时代在各地不尽相同，它起自早二叠世晚期——茅口期并一直延续至二叠纪末。对二叠纪古气候所作的概略分析表明，整个二叠纪在华南都是成煤期，只要古地理条件有利，在早二叠世的栖霞期和茅口期以及晚二叠世的龙潭期和长兴期都可以生成煤层。

Synthetic analyses based largely on the platform/inner shelf trilobite faunas suggest that the Chinese eastern Peri-Gondwanan plates and terranes may have belonged to a single biogeographic province during the Tremadocian and the late Katian-Hirnantian, but may be divided into two sub-provinces during the Floian-early Katian (Arenig-Caradoc): One consists of South China, Tarim and Annamia, and the other may include North China, Sibumasu, southern Tibet, Tianshan-Beishan and possibly Hainan.

对这些属于东泛冈瓦纳的中国区块的台地或内陆棚三叶虫动物群的综合分析研究证明，它们在特马豆克期以及凯迪晚期－赫南特期(late Katian-Hirnantian)或阿石极期应归属同一生物地理区，而在弗洛期－凯迪早期(Floian-early Katian)或阿仑尼克期－卡拉多克期(Arenig-Caradoc)则可划分为两个生物地理亚区：一个由华南、塔里木板块和安南或印支地体组成，另一个包括华北板块以及滇缅马、藏南、中天山－北山地体。

Result: Lump static issue and acute inflammation issue lump issues of best breakthrough point that treat, and the traditional Chinese medicine can make to treat lump dissipating or limitation, create conditions for treating succeeding in in disposable operation. Accept thick liquid cellulous mastitis lump issues of 12 of patient for medical treatment altogether will it be February 2005 will it be July 2004, 11 acute inflammation one among them, this group in order to optimize healing solution treat and as treat group , regard patient of one of the acute inflammation when reviewed of the case as contrast group patient, statistical analysis is drawn : In curative effect, damage big or small treating group is it contrast group to superior to on the main improvement of symptom.

结果：肿块静止期和急性炎症期是肿块期治疗的最佳切入点，而中药治疗可使肿块消散或局限，为一次性手术治疗成功创造条件。2004年7月—2005年2月共收治浆细胞性乳腺炎肿块期病人12例，其中11例为急性炎症期，将此组病人以优化治疗方案治疗并作为治疗组，将病例回顾中急性炎症期的病人作为对照组，统计分析得出：在疗效、损伤大小、主要症状的改善上治疗组均优于对照组。

The increase in either OCDAS or AAS scores associated with provocation was statistically significant (P＜0.01). A statistically significant increase (P＜0.05) in rCBV during the OCD symptomatic state versus the control state was found in the right inferiofrontal cortex, postcentral cortex, angular cortex, and bilateral orbitofrontal cortices, cuneus cortices, heads of caudate neucli, thalami and amygdalae.

结果 静息期和诱发期的强迫症状评分结果分别是1.00±0.33和6.65±0.71，有显著性差异（P＜0.01）；静息期和诱发期的焦虑症状评分结果分别是1.20±0.42和2.75±0.42，也有显著性差异（P＜0.01）；与静息期相比，右侧额下回、中央后回、角回、双侧眶额部、楔叶皮质及双侧尾状核头、丘脑、杏仁核rCBV在症状诱发期显著增加（P＜0.05）。

Suppression subtractive hybridization cDNA plasmid libraries were constructed between gastrula embryos and tail bud embryos in gynogenetic gibel carp.739 and 816 PCR positive clones were respectively selected to perform dot blot,and 72 dot blot positive clones and 98 dot blot positive clones were obtained from the SSH plasmid libraries specific for gastrula embryos and tail bud embryos.

构建了雌核发育银鲫原肠期胚胎和尾芽期胚胎间的抑制性差减杂交cDNA质粒文库。对原肠期739个和尾芽期816个PCR阳性克隆进行斑点杂交，得到72个原肠期和98个尾芽期斑点杂交阳性克隆。

Results The number of CEC and the expression of HSP70 of HFRS patients began to increase in the fever stage and maintained a high level in the hypotension and oliguria stages then gradually decreased in the diuretic phase and the recovery phase. In patients with different clinical types of HFRS the CEC number and the HSP70 level accordingly increased and reached the peak in severe and dangerous HFRS.

结果 在不同病期的HFRS患者中，CEC计数及HSP70的表达在发热期已升高，在低血压期和少尿期持续高水平，至多尿期及恢复期逐渐降低；在不同临床类型的HFRS患者中，随病情加重，CEC数量及HSP70的表达亦相应增高，在重型和危重型患者中达到高峰。

objective to study the changes of t-pa and t-pa inhibitorduring the acute stage of cor pulmonale.methods to measure the plasmatic activity of t-pa and pai by chrom-substrate in60cases of cor pulmonale,compared with the corresponding index of55cases in the control group.results pai was significantly higher in acute stage than in remission stage of corpulmonale,and t-pa was lower in remission stage than in acute stage.the difference was significant（p.01）.conclusion the unbalance between t-pa and pai can promote the formation of micro-thrombus and further exacerbate high pulmonary pressure.

目的 探讨血浆组织型纤溶酶原激活物及t-pa抑制物在肺心病急性加重期的变化。方法用发色底物法测定60例肺心病急性加重期的血浆t-pa及pai的活性，并与对照组55例肺心病缓解期的相应指标作比较。结果肺心病急性加重期患者pai显著高于肺心病缓解期，而t-pa低于肺心病缓解期，其差异具有非常显著性（p.01）。结论 t-pa及pai关系失衡，有助于动脉内微血栓形成，促进或加重肺动脉高压的形成。

Stage I of both male and female stone flounder appears only once in all its life, and the germ cells are comprised by spermatogonia or oogonia. The gonad from Mar to Aug keeps at stage II. The gonad index of testis at this stage is 0.037%, and the amount of spermatogonia is increased quickly. There is some linear germ plasm in the cytoplasm of spermatogina. In ovary at this stage it is mostly composed by oocyte of phase 2 which the character is the appearance of yolk nucleus, and no zona radiate in membrane. The mean GI of ovary is 1.95%. From Sep to Oct gonad is at stage III which testis is composed by lots of spermatogina and few spermatocytes, and the mean GI of testis at this stage is 0.086%. In ovary the ooctyes at phase 3 are in dominate position, the yolk nucleus disappear. And the GI of this stage is 3.35%. Both testis and ovary are at stage IV in Nov. hi testis the germ cells are in spermiogenesis, and the mean GI is 0.93%. hi ovary the oocytes are mostly at phase 4, which are filled in the cytoplasm with vitellin granule, and the zona radiate in membrane begins to formation. Nucleus moves to one side of the oocyte gradually. The mean GI of ovary at this stage is 9.37%.
