LTT was assayed by 3 H - TdR incorporation method.

外周血淋巴细胞转化率测定采用3H - TdR渗入法.

A light tracing tree (LTT) can be set up according to the light tracing theory and the covering area can be simulated using the information saved in the nodes of the LTT.

该算法根据光线追踪理论和有关光学原理建立光线传播树，并通过可视化方法在计算机上对光线照射到的区域进行仿真。

It has the rather catchy name LTT 1445Ab, as it orbits the primary star of three red dwarfs that constitute the system LTT 1445, located around 22.5 light-years away.

这颗星球有个很惹眼的名字：LTT1445Ab。因为它围绕着组成LTT1445系统的三颗红矮星构成的主恒星旋转，距离地球约22.5光年。

LTT 1445Ab is very different from the 2016 discovery of HD 131399Ab, another exoplanet with three suns.

LTT1445Ab与2016年发现的另一个有“三个太阳”的系外行星HD 131399Ab差别很大。

Based on the model, calculation formula of available light-triggered current and turn-on condition in LTT arc obtained.

由建立的模型推出了LTT内部产生的有效光触发电流公式及LTT开通条件。
