This is caused by adding one start bit and one stop bit to an eight bit word — thus 2 bits out of ten.

这是由于在一个8位字中加入了1个起始位和1个停止位，也就是10位中的2位。

The analysis of SAR reveals that the activities of target compounds are closely associated with the electron-withdrawing substituents at the para position of 1-aryl-1, 2, 4 -triazoles as well as with the substituents such as sulfonyl and methylthio groups at the 3 position of 1, 2, 4 -triazoles; And the introduction of sulfamoyl moiety at the para position of 5-aryl-1,2,4-triazoles also has significant influence on the anti-inflammatory activity of these compounds.

Cinnabarinus at 150 mg/L.The influences on bioactivity of substituted pyrazole and pyrimidine were discussed respectively: pyrazoles substituted with phenyls at 3 position had higher activity than thiophen and compounds with R_1=methyl had higher activity than that with R_1= hydrogen, pyrimidines substituted with methyl at 2 (R_3) and 5 (R_3) position and phenyl at 6 position were most active.

本论文对吡唑及嘧啶取代基对活性的影响分别进行了讨论，可知：吡唑3位为取代苯基的化合物杀菌活性优于取代噻吩的，吡唑4位(R_1)为甲基的杀菌活性高于R_1为氢的活性；嘧啶的2位(R_3)为甲基，5位(R_1)为甲基，6位为无取代基的苯基时活性最好。

The spectrum peaks nearby 530nm and 480 nm are corresponding with BTSD and BMD respectively. It is found from measurement that the luminescence peak from BMD is bluely shifted. The atoms of BTSD nearby dislocation core are affected by tensile stress along the Burger's vector direction leading to its band gap narrowed. In addition, there is the effect of part quantity of edge dislocation in BMD existed. Part of atoms in BMD are strained by compressive stress leading to its band gap narrowed, in other words, the wavelength from BMD is shorter than that from BTSD.

从测试结果中还发现BMD 的发光位较BTSD有所蓝移，分析认为BTSD位错芯附近原子沿伯格斯矢量方向只受到拉应力，致使禁带宽度变窄，BMD由于除了具有螺型位错的分量外还具有部分刃型位错的分量，而刃型位错中有部分原子受到压应力的作用，导致禁带宽度增宽，从而使得BMD的发光波长比BTSD短
