查询词典 fossa cubitalia

Chiari malformations are a spectrum of anomalies associated with a reduction of posterior cranial fossa volumes and CSF while conserving overall brain volume. Chiari I malformations refer to a greater than 5 mm herniation of the cerebellar tonsils down through the foramen magnum.

chiari畸形是由于后颅窝容积及脑脊液减小而与正常的脑容积不匹配造成的一系列的异常病变的统称。chiariI型畸形是指小脑扁桃体下疝超过枕骨大孔5mm以上。

Results The mean dose to 90% of the cochlea was reduced from 39% of the prescribed posterior fossa boost dose to 1.6%,and the 90% mandibular joint volume was 26.1% and 0.4% for the Xrays and proton respectively.Mean dose to the 50% heart volume was reduced from 63.3% to 0.8%,and 90% thyroid volume was 72.2% and 0.5% for the Xray and proton respectively.

结果 X线与质子适形放射治疗计划相比，右侧耳蜗90%的体积平均受照剂量分别为后颅窝加量野的39%和1.6%，右颞颌关节90%体积平均受量分别为26.1%和0.4%， 50%心脏平均受照剂量分别为脊髓野处方剂量的63.3%和0.8%，90%甲状腺平均受量分别为72.2%和0.5%。

According to our present broadcasting situation,the thesis proposes using new technology to update and reform the present HFC. It also suggests broadcasting using self-advantage and arranging EPON in order to win the supermarket.

论文从我国广电的现状出发，结合实际，积极倡导采用新技术更新、改造我国现有的HFC网络；倡导广电现阶段利用自身优势，部署EPON网络来赢取市场。

A new general kinetic equation was derived in which the effect of the removal of condensation water was taken into account completely, and was applied to the polyesterification kinetic study of AA/HPHP and AA/NPG. It was found that the reaction order of self-catalyzed polyesterification was not constant. For these polyesterifications, the reaction order was 2.5 at a low temperature, while 3.0 at a high temperature.

考虑缩合水的排除对反应体系的影响，用体积浓度单位推导出一个新的聚酯反应总包动力学方程，并应用到AA/HPHP和AA/NPG两个聚酯化反应的动力学研究中，研究发现，自催化聚酯反应的反应级数并不是固定值，对于AA/HPHP和AA/NPG两个聚酯化反应而言，低温时反应级数为2.5，高温时反应级数为3.0。
