Disc cell mainly consist of chondrocytes, PTHrP-Ihh negative feedback mechanism can modulate differentiation and maturation of chondrcytes during endocartilage ossification in epiphysis of long shaft bone, but its effect on vertebral development is still unknown.

椎间盘细胞主要由软骨细胞样细胞组成，PTHrP和Ihh形成的负反馈机制在长管骨软骨内骨化过程中对软骨细胞分化和成熟具有调节作用，在椎体和椎间盘的发育过程中的作用仍未阐明。

Broadband matching is very difficult, but we can make it easier with negative feedback and balanced amplifier.

宽带匹配网络的设计是一个难点，可以采用负反馈、平衡电路等形式降低宽带匹配的难度，所以宽带电路的设计首先是方案设计。

While working on a means of reducing amplifier distortion, he devised the negative feedback amplifier.

It is also found that the level of IL-18BPa has a negative correlation with PASI score. This finding indicates that IL-18BPa as an inhibitor decreases in the plasma of psoriatic patients.

我们既往的研究发现银屑病血清中存在细胞因子异常，本文的研究发现银屑病患者血浆中IL-18BPa的浓度比正常人减少，进行期血浆中的浓度最低，退行期血浆中的浓度与正常人相近，与银屑病PASI评分呈负相关性，说明在银屑病外周血中存在抑制因子IL-18BPa的下降，IL-18/IL-18BP负反馈环路的异常，使Th1反应增强，可能在银屑病的发病机制中起到重要作用。

Means the parent directory, so this command means to execute "toolchain.sh," which is in the current directory.

代表父目录，所以这个命令就是执行当前目录下的"toolchain.sh"。

Yes,In fact,I'm on our city ream.

是的。事实上我是我们市队的。
