查询词典 MA

The activity of polygalacturonase,PME,cellulase and the soluble pectin content of MA stor-age were significantly lower than those of control; while the flesh firmness,cellulose content ,protopectin content were sig-nificantly higher than those of control. Results showed that MA storage retarded the softening process of mulberry fruit.

研究了在(2±1)℃下，MA贮藏对桑果细胞壁组分和水解酶活性的影响，结果表明：MA贮藏可抑制桑果呼吸强度和乙烯释放量，MA贮藏桑果的纤维素酶、果胶甲酯酶和多聚半乳糖醛酸酶等细胞壁水解酶活性和水溶性果胶含量显著低于对照，而果实的纤维素和原果胶含量显著高于对照，从而延缓桑果的软化。

All the LOH on 〓 and 〓 was observed in invasive ductal carcino- ma, carcinoma simplex, medulary carcinoma and scirrhous carcino- ma, no deletions at these sites were observed in any invasive lobular carcinoma and others. These results imply an etiological difference.P53 gene is a hot point gene in the occurrence and development of breast, cancer. PCR-SSCP analysis was performed to detect P53 gene point mutation in the region between exon 5 and 8, 5 of 12 (41. 6%) stage I breast cancer patients contain mutation of P53, 3 of 5 patients were accompanied by 〓 deletion. These results suggested that point mutation and allelic loss of P53 gene are two vi- tal genetic events in earlier stage of breast tumorigenesis.

我们还发现，〓和〓位点LOH均分布在乳腺浸润性导管癌、单纯癌、髓样癌及硬癌中，在浸润性小叶癌和某些特殊类型乳腺癌中全部为LOH阴性，上述位点LOH可能与某些组织学类型乳腺癌的发生有关。P53基因是乳腺癌形成过程中的一个热点基因，本研究对12例Ⅰ期乳腺癌组织标本中P53基因热点区域第5、6、7、8外显子点突变进行了测定，发现41.6％（5／12）的病人有P53基因一个或多个点突变，其中3例同时伴有〓位点LOH，表明P53基因点突变和等位基因缺失是发生在乳腺癌形成早期的一个重要遗传学事件。

Firstly,~(40)Ar/~(39)Ar age clusters of Ma reveal the fast cooling of eastern Himalaya Syntaxis since middle Pliocene. Secondly, the difference of ~(40)Ar/~(39)Ar age clusters between the west and east slope section of DuoxiongLa is the result of a titling structure, which strikes NE at the west side of Namjag-Barwa– NamuLa– DuoxiongLa, and which has been functioning since 4.0~2.2 Ma under the drive of both climatic and tectonic powers.

一方面，大量小于3 Ma的~(40)Ar/~(39)Ar年龄表明东构造结的大规模隆升开始于上新世中期，另一方面，多雄拉东坡与西坡~(40)Ar/~(39)Ar年龄的差异是由于南迦巴瓦—那木拉—多雄拉峰顶连线以西发育的北东走向掀斜构造所引起的差异性抬升和剥蚀所造成，该掀斜构造开始发育于4.0～2.2 Ma期间，且一直活动到现在，其动力源自气候与构造的共同作用。

The nano-silica partrcles are organic-modified by E-MA-GMA elastomer through direct solvent process,the organic-modify process mechanism was studied,and the dispersing of modified nano-silica particles in tetrachloroethane solvent and PBT were investigated.FIRT,TEM,SEM results indicated that the epoxy group of E-MA-GMA could react with the hydroxyl groups of silica surface,helped to reduce the interactions of nano-silica particles particles and improve the dispersion of nano-silica on PBT and the interfacia...

surface modification ；溶液法利用功能化弹性体E-MA-GMA对纳米二氧化硅进行表面有机化修饰改性，分析了表面改性过程机理，同时考察了改性后纳米二氧化硅在四氯乙烷溶剂和PBT基体中的分散情况；FIRT、TEM、SEM测试结果表明，E-MA-GMA的环氧基团与纳米SiO_2的—OH基团发生反应，降低纳米二氧化硅粒子间的相互作用力，改善了纳米二氧化硅在PBT基体中的分散，提高复合材料的相容性。

Eclogites north of the fault give similar Sm–Nd isochron ages (131–126 Ma) but otherwise differ in that they are strongly overprinted by a lower pressure assemblage and, along with associated HP/LT rocks, give much younger 40Ar/39Ar ages of 88–55 Ma indicating a later amphibolite facies metamorphic event.

榴辉岩断层以北的始可予以实现位置相似的Sm - Nd同位素年龄（131-126 Ma）的方式不同，但他们强烈较低的压力叠加和组合，以及相关的惠普/审裁处的岩石，让更年轻的40Ar/39Ar年龄在88-55马说明后来角闪岩相变质事件。

The deposit has yielded a 187Re-187Os isochron age of (15.32±0.79) Ma, which is identical to the age (14 Ma±) of porphyry copper mineralization in the east Gangdese belt.

年龄数据与冈底斯成矿带东段南侧斑岩铜矿化带的矿化时间(14 Ma左右)具有一致性，表明北矿带的成矿作用与斑岩有关。
