In contrast to the situation for a homogeneous isotropic neo-Hookean sphere, it is shown that not only there exists a secondary turning bifurcation point on the cavitated bifurcation solution which bifurcates locally to the left from trivial solution, and also the critical load is smaller than that for the material with no perturbations, as the parameters belong to some regions.

与均匀各向同性的neo-Hookean球体的情况相比,证明了当摄动参数属于某些区域时,从平凡解局部向左分岔的空穴分岔解上存在一个二次转向分岔点,空穴生成时的临界载荷会比无摄动的材料的临界载荷小。

The two volcanic materials are similar but are also different ①the partition mode of rare-earth element is similar to that of the basalt.②the increase content of the rare-earth element content in transitional layer shows that it enrichs in this segment due to the volcano events. Moreover, the comparability of the partition mode shows that the volcano-genic materials and the basalt are of the same source.③low Eu anomaly different from the high Eu anomaly of medium-acidic tuff in Meishan section, that show that their formation is different④there are plentiful basalt detritus.⑤there are enrichment of the Ti element.⑥the lower content of siderophile element of Ni and Co, especially in the transitional layer, show that there were not extraterrestrial events and big scale basic or ultrabasic volcano eruption events in this area. These characteristics show that the sedimentary source of Xuanwei Formation and Kayitou Formation is basalt.

1稀土元素配分模式与玄武岩类似;(2)稀土元素含量在异常层的增加反映了火山事件导致了它在该段地层中的富集,而配分模式的相似性反映了火山物质来源与玄武岩具有同源性;(3)低"Eu"异常区别于煤山剖面的中酸性凝灰岩高"Eu"异常模式,说明界线粘土岩成因也不同于煤山剖面的界线粘土;(4)大量的玄武岩岩屑;(5)Ti元素的富集;(6)亲铁元素Ni和Co含量较低,特别是在界线异常层含量降低,表明本区在界线处可能并不存在地外事件和大规模基性、超基性火山喷发事件,这些特征反映本区宣威组和卡以头组物质来源主要为玄武岩。

objective to evaluate the role of mr perfusion weighted imaging in preoperation diagnosis of meningiomas.methods mr perfusion weighted images was performed in 47 patients with meningiomas followed by conventional imaging.results the mean rcbv values of angioblastic was the highest in the parenchyma of tumor.the mean rcbv values of malignant group was the lowest.the biggest mean rcbv values among different type meningiomas was statistically significant.the biggest mean rcbv values between benign and malignant group meningiomas was statistically significant,but not in the peri-tumor edema.conclusion the rcbv values were useful in the preoperative differentiation diagnosis of different types of meningiomas.those in the peri-tumor edema were useless in the preoperative differentiation diagnosis of different types of meningiomas.

目的 探讨磁共振灌注成像技术对脑膜瘤术前分型及良恶性鉴别的临床应用价值。方法对47例脑膜瘤病人行mr灌注成像检查,对5种亚型的良性脑膜瘤的mr灌注成像进行分析,并与非典型性及恶性脑膜瘤进行比较。结果血管瘤型脑膜瘤实质部分的rcbv值均数最高,恶性组脑膜瘤的rcbv值均数最低。各亚型间瘤体实质最大rcbv值均数间差异有统计学意义(p<0.05),良恶性脑膜瘤实质部分最大rcbv值均数间差异有统计学意义(p<0.05)。瘤周水肿区的rcbv值均数间差异无统计学意义(p>0.05)。结论 rcbv值对脑膜瘤术前分型及良恶性鉴别有所帮助,而瘤周水肿区的rcbv值对脑膜瘤分型及良恶性鉴别未显示临床实用价值。
