It shows that the FE method of tireanalysis under driving state and the method dealing with large slip frictionalcontact problems are correct and reliable. The properties of tires under steady cornering state are studied with FEmethod and experiment. Based on the presented contact solution algorithm, a FEmethod is carried out to analyze the properties of tire under steady corneringstate via imposing slip-rolling-constraints on tire bead nodes which contact therim, and the modules are programmed. The mechanical properties anddeformation of tire under pure steady cornering state and steadycornering-driving state are analyzed, and the results show good agreement withthe experimental data.

对匀速侧滑条件下轮胎侧偏特性进行了试验研究和有限元分析研究，基于本文提出的大滑动摩擦接触问题求解方法，通过在胎圈和轮辋接触节点上施加侧偏滚动约束，得到了匀速侧滑条件下轮胎侧偏特性有限元分析方法，编制了有限元分析模块；利用本文给出的有限元分析方法，分析了轮胎在匀速纯侧滑和侧滑-纵滑联合工况下受力变形特性，分析了侧偏角和载荷对轮胎侧偏特性的影响。

MACS is a simple and effective method in isolating monocyte/macrophages from peripheral blood and decidua in early pregnancy, which may be helpful to study the role of immune cells in maternal-fetal immune tolerance.

MACS方法是一种有效，简捷的分离、纯化单核巨噬细胞的方法，运用此方法，有益于更确切的描述妊娠早期参与母胎界面免疫调控的职能细胞的作用及其调节方式。

RESULTS: There were good results after benign teratoid tumor extrated or combined lobectomy or decortication.

结果：良性畸胎类肿瘤手术摘除或合并肺、胸膜切除后效果良好。

In cases of seere demineralization of the bony calarium, superisualization of intracranial structures may be noted.

在胎头的两个轴向切面所见的颅内结构"超清晰显示"，这是在成骨不全中因骨化不足所致。

Results: 4 cases were geminoma, 3 cases were teratoma, 1 case was choriocarcinoma, 4 cases were glioma, 2 cases were meningiomas, pineoblstoma, neuroblastoma, dermoid cyst and arachnoid cyst each had one case. It maybe very difficult if we diagnosed only through MR signals. Due to the multitude origin of histology, we can diagnose through some special signals, such as adipose, cystic degeneration, hemorrhage and implant dissemination. We can also combined with clinical examination which is help to differential diagnosis.

结果：生殖细胞瘤4例，畸胎瘤3例，1例绒毛膜癌，胶质瘤4例，脑膜瘤2例，松果体母细胞瘤、神经母细胞瘤、皮样囊肿及蛛网膜囊肿各1例，仅通过MR信号较难诊断，由于肿瘤组织学来源多，可通过一些特殊信号如脂肪、囊变、出血、种植播散等，并结合临床检查来进行鉴别诊断。

There were 36 males and 40 females,with the average age of 47.7 years.36 patients presented with sciatica and perineal numbness,11 patients had painless mass and the other 20 were identified due to other causes.Among 67 benign neurogenic tumors,54 were originated from S1-S3 nerves,3 from S4-S5 nerves and 11 from the presacral space without caudal involvement.Giant cell tumor was found in 60 patients,which included 24 males and 36 females,with an average age of 32 years.Upper sacrum（S1-S2） was involved firstly.There were 56 patients（average,37.7 years） diagnosed as other primary benign bone tumors,which included 24 cases of teratomas,epidermoid cyst or dermoid cyst.Other malignant tumors,including chondrosarcoma （17）,Ewing′s sarcoma/PNET（14）,multiple myeloma（12）,lymphoma（6） and osteosarcoma（6） were found in 64 patients.

其中脊索瘤95例，男62例，女33例，平均年龄55.7岁，骶尾区疼痛是主要症状（82例），半数以上患者伴有坐骨神经痛，肿瘤多先累及低位骶骨（S3~S5）；神经源性肿瘤76例，男36例，女40例，平均年龄47.7岁，神经纤维瘤43例，神经鞘瘤24例，恶性神经鞘瘤9例，主诉多为坐骨神经痛、会阴部麻木（36例）和无痛性包块（11例），20例患者为查体或其他原因检查时发现，67例骶骨良性神经源性肿瘤起源于S3以上神经者54例，起源于S3以下神经者3例，发生于骶前未累及骶管者10例；骨巨细胞瘤60例，男24例，女36例，平均年龄32岁，腰骶尾部不适（37例）、坐骨神经痛（21例）是主要的临床表现，肿瘤多先累及上位骶骨（S1~S2）；骶骨其他原发良性肿瘤及瘤样病变56例，包括畸胎瘤、皮样囊肿、表皮样囊肿共24例；其他原发恶性肿瘤64例，包括软骨肉瘤17例，尤文肉瘤14例，多发性骨髓瘤12例，成骨肉瘤6例等。
