The properties and expression of knowledge are discussed in brief and binary and multiple truth expression and inference of knowledge are studied focally. The neural networks which can realized the three valued logic are overviewed. The new idea of uncertain inference based on three valued logic is proposed for the first time The models of neural logic, which can realize three valued logic and uncertain three valued logic inference are proposed, too. The learning algorithm of coefficient of MVL's function based on the canonical realization of MVL network is investigated for the first time and the appropriate algorithm is proposed.

4简要地论述了知识的特征及其表现形式，重点研究了知识的真值二值和多值表示法以及基于知识真值表示法的逻辑推理；通过对目前可实现三值逻辑推理的逻辑神经元及其网络的简要回顾，指出了各自的局限性，首次提出了基于三值逻辑的不定性推理的新概念以及可实现三值逻辑和三值逻辑不定性推理的逻辑神经元模型，同时对基于这种逻辑神经元模型的推理系统的应用领域进行了探索性尝试；另外，首次对基于多值逻辑网络正规实现的多值逻辑函数的系数参数的学习算法进行了研究，并提出了相应的学习算法。

There were significant differences (P＜0.05) between cock's and hen's body length, chest bone length, thurl width, shank circumference in some Chinese indigenous chicken breeds. There were significant differences (P＜0.05) between cock's and hen's shank length among 12 Chinese indigenous chicken breeds. The differences showed that some genes controlled sex may be responsible for the differences of sexuality, on the other hand, they affected cock's and hen's body measurements and body weight, that is one gene has multiple effects.

大部分地方鸡品种12周龄公、母鸡在体斜长、龙骨长、骨盆宽、胫围和体重之间存在显著的差异（P＜0.05），12个地方鸡品种内12周龄公、母鸡胫长之间均存在显著差异（P＜0.05），这些结果说明了控制公、母鸡性征的一些基因，一方面使公、母鸡在性征的表现上存在差异，另一方面这些基因也对公、母鸡的体尺和体重等性状起着一定的作用，即表现为一因多效的作用。

The mountain materials, Russia expected, the Qinghai-hat "tremolite" small crystals have a certain arrangement of different materials, such as Qinghai, the crystal fibers are arranged mostly in the same direction, showing a translucent and strong, and this has not been a natural Sorting mountain materials, micro-fractured, micro-cracks will affect the diffuse light glossy surface, it is generally not a good oil lubrication performance sense, but there are also individual mountain material, because structure is very good, so oil is also very good, used to play, and Tian's friends must have taken note of this in!

而山料、俄料、青海料"透闪石"小晶体的排列方式有一定的不同，如青海料的晶体纤维的排列多为同一方向，表现出透光性强，并且这种没有经过自然分选的山料，微裂隙发育，微裂隙对光漫反射会影响表面的光泽感，所以一般表现不出很好的油润感，但也有个别的山料，由于结构非常好，所以油性也非常好，经常玩和田玉的朋友一定也注意到这一点了！

Polycystic ovary syndrome is an endocrine disorder with a variety of etiopathogensis and clinic manifestations, Hitherto its pathogenesy is still uncleared, However, there have been increasing supports for the contribution of the hyperinsulinism and hyperandrogenaemia in the pathological process of the PCOS.

多囊卵巢综合征(polycystic ovary syndrome， PCOS)是一种发病呈多因性、临床表现呈多态性的内分泌紊乱综合征。其发病机制至今尚未阐明，既往研究认为高胰岛素血症与高雄激素血症在PCOS发病机制中发挥着重要作用。

Multilocular cystadenomas have the typical MRI manifestations and MRI is valuable, whereas unilocular cystadenomas, having similar MRI findings with some other benign cystic lesion, are lack of enough features in MRI. However, thick irregular wall or septa in MRI might be helpful in differential diagnosis.

多房性囊腺瘤具有较典型的MRI表现，诊断不难；单房性囊腺瘤缺乏特异表现，囊壁强化是与其他囊性病变鉴别诊断的重要徵象，MRI检查对诊断有重要作用。

There were 22 cases with febrile, 8 cases with wheezing, 9 cases with accelerated breathing, and all of them were with some extent clinical manifestations of other system except lungs, such as nausea, vomitus, diarrhea, sinusitis, dental ulcer, otitis media, rash, arrhythmia and so on.

结果：28例临床表现均有咳嗽，多为刺激性干咳，伴发热22例，喘憋8例，气促9例；同时均伴有不同程度的肺外表现，如恶心、呕吐、腹泻、鼻窦炎、口腔溃疡、中耳炎、皮疹、心律失常等。

Fourteen wampee cultivars collected from Guangdong and Guangxi were used for RAPD analysis in this study. 16 primers selected from 150 random primers were used to amplify 87 DNA fragments and 57 bands (54.0%) showed polymorphisms.

摘 要：对14个黄皮品种进行 RAPD 分析，从150个随机引物中筛选出16个能在种质间表现出多态性的引物，共扩增出 87 条谱带，其中多态性带47条，多态性比例为54.0%。

objective to study mri diagnostic value on multiple sclerosis.methods mri examination data of 31 patients with multiple sclerosis were analysised retrospectively.results total 184 lesions were detectived in 31 patients.most lesions were located on white watter area beside the lateral ventricle,and a few lesions were located on the spinal cord,cerebellum,brain stem and corpus callosum.the shape of lesion can be circle or ellipse.the lesion showed as slightly long t1 and long t2 signal.the acute stage lesions can have enhancement.conclusions ms have characteristic findings on mri image.mri can show the patholoic changes,and provide strong evidence for clinic diagnosis of multiple sclerosis.

摘 要］目的：探讨多发性硬化（muliplle sclerosis，ms）的mri特征表现及其诊断价值。方法：回顾分析31例临床诊断为ms患者的mri检查资料。结果：31例共发现病灶184个，病灶于侧脑室旁白质区、半卵圆中心及皮层下区最多见，其次见于脊髓小脑、脑干及胼胝体，部分可见视神经受累，病灶呈卵圆形或圆形稍长t1、长t2信号，矢状位像见病灶与侧脑室垂直，急性病灶增强扫描有的可呈结节状、环状或斑点状强化。结论：在mri图像上ms有特征性表现，mri能反应ms病理变化，为临床诊断ms提供可靠依据。

For example, Pudovkin in the "end of St. Petersburg," one in two shots on such series: First performance of front line combat soldiers lay dying in the mud; the other is the performance that was wild excitement of the zaibatsu were fictitious in the skyrocketing stock market.

例如普多夫金在《圣彼得堡末日》一片中，有这样两个镜头的对列：一是表现在前线上作战士兵奄奄一息地躺在泥里；另一个是表现那些兴奋的发了狂的财阀们在暴涨的股票市场上买空卖空。

Polycystic ovary syndrome , one of the most common endocrine diseases affecting women of reproductive age, plays an important role in anovulatory infertility, with a prevalence of up to 5%~21%; The main clinical manifestations include irregular menstruation (amenorrhea or infrequent menstruation or dysfunctional uterine bleeding), infertility, hirsutism, obesity and acanthosis nigricans. Elevated serum LH levels and hyperandrogenism, insulin resistance with compensatory hyperinsulinemia are its endocrinological features. Polycystic ovary morphology is also a common feature in PCOS. With the advance researches, PCOS displays its complexity and essential trend.

多囊卵巢综合征(polycystic ovary syndrome，简称PCOS)是育龄期妇女最常见的内分泌紊乱性疾病之一，在不排卵性不孕中占主要地位，发病率约5%～21%；主要表现为月经异常、不孕、多毛、肥胖及黑棘皮征，以高雄激素血症、促性腺激素异常、高胰岛素血症及胰岛素抵抗等内分泌学特征，以双侧卵巢增大呈囊性改变并间质增生为病理形态学基础的多系统疾病。
