Schedule an appointment with an audiologist if your child has trouble learning letter sounds (particularly short vowels, such as "u" and "o"); confuses similar-sounding words (such as "on" and "in," or "to" and "through"); or asks questions that have already been answered.

如果你的孩子在学习字母发音上有困难，那么事先制定一个听力的计划。（特别是短元音，如" U "型和" O "）；混淆相似的词（如"上"和"中"或"去"和"通过"）或是问一些已经被回答过的问题。

By the single zircon U Pb dating method, the quartz syenite porphyny yielded an age of concordance (1 731±29)Ma, and the aegirine augite syenite and syenogebbro are dated upper cocordi...

应用单锆石U Pb法测定年龄，石英正长斑岩谐和年龄为( 1731± 2 9)Ma ，霓辉正长岩、正长辉长岩上交点年龄分别为( 1644± 14)Ma、( 1750± 65)Ma.1650～ 170 0Ma是碱性岩浆活动热构造事件的标志，石英正长斑岩被中元古代晚期的高山河组不整合覆盖，故以 1650～ 170 0Ma作为熊耳群的上限。1650～ 170 0Ma热构造事件是华北地块重大地质事件，有可能是进一步划分中元古代重要的年龄界限。

The testing method contained fibrin plate assay, direct and indirect chromogenic assay, SDS-PAGE fibrin autography, and visual exhibition of the complexes between rPAI-1 and t-PA or low molecular weight u-PA on SDSPAGE.

所使用的方法包括：纤维蛋白平板法，直接和间接的显色底物法，SDS-PAGE纤维蛋白自显影法，以及用SDS-PAGE直接显示rPAI-1与t-PA和低分子量u-PA形成的复合物。

Let G be a finite group, and S a subset of G not containing theidentity element 1. The Cayley digraph Cay on G with respect to S is definedas a directed graph with vertex set G and edge set {|g∈G, s∈S}. IfS~(-1)=S, then Cay is undirected and in this case, we view two directededges and as an undirected edge {u, v}. Obviously, the right regularrepresentation R of G, the acting group of G by right multiplication, is asubgroup of the full automorphism group AutCay(G, S of Cay.

给定有限群G，设S是G的不含单位元1的子集，群G关于子集S的Cayley有向图Cay是一个以G顶点集合，而以｛|g∈G，s∈S｝为边集合的有向图，特别地，若S~(-1)=S，则X=Cay是无向的，此时我们把一条无向边｛u，v｝等同于两条有向边和，易见，群G的右正则表示R，即G在G上的右乘作用，为图Cay的全自同构群AutCay
