FCGR

Objective: Our paper was designed to compare the effects of Fcgr 2 b allele and H 2 complex on production of serum IgG antibodies in systemic lupus erythematosus ( SLE) model ( NZB × NZW) F 1 mice.

目的：比较Fcgr2b基因单独及与H－2复合体共同作用对自发性狼疮小鼠（NZB×NZW）F1血清IgG抗DNA抗体产生的影响。

Two series of fatigue crack growth rate ( FCGR) tests using three point bend specimen with different integral knife edge designs are performed. Effect of elastic modulus on the measurement of fatigue crack length using compliance technique is analyzed.

用不同整体刀口设计的三点弯曲SE（B）试样做了两组疲劳裂纹扩展速率（FCGR）试验，分析了弹性模量在柔度法测量疲劳裂纹长度中的影响。

FCGR will decrease with thicker sample and smaller stress ratio at the same testing condition.

在相同实验条件下，试样厚度越大、应力比越小，疲劳裂纹扩展速率越低。

We defined the transition of FCGR as a fatigue ductile-brittle transition temperature ( FDBTT).

本文将疲劳裂纹扩展速率发生转折的温度定义为疲劳裂纹扩展的韧脆转化温度FDBTT。

The fatigue crack growth rate ( FCGR) of 4130X steel in H2S environment is researched in this paper.

研究了4130X钢在硫化氢（H2S）腐蚀介质中的疲劳裂纹扩展速率da／dN。
