The measure unit adopts RENISHAW LP2DD probe. HEIDENHAIN linear and round encoders of the machine can as position feedback element. The measure system uses interruptive function of CNC system. When the probe is touched, CNC system will receive a interruptive signal and memory current coordinate position of CNC axes automatically, then after software deals with these information, the real measure data will be got. Compared with theory data, measure error data will be gained.

Rat glioma cell C6 was infected by the deficiency recombinant retrovirus (named C6TK). The sensitivity of C6TK cells to GCV or ACV increased 450 or 10 times than that of C6 cells respectively. Rat C6 glioma model was successfully built, and SD rats inoculated intracerebrally C6TK cells had normal gliomas. The average survival periods of the rats were about 15 days. However, after treated with ACV, the growth of C6TK tumors obviously regressed, and the survival periods extended to 57.8±8.1 days, especially in rats injected with mixed PA317TK and C6 cells or in situ PA317TK cells, which the tumors nearly disappeared after ACV administration and the survival periods extended to over 120 or 71.4±36.1 days respectively, P<0.001.

Johannsen experimented with the Princess bean and found that if the self-fertillzing parent plants were from a mixed population, then selection did indeed work. He described the offspring of single parent as a ' pure line ' and stated that they were genetically identical. In 1905 he coined the terms ' phenotype ' to describe the outward appearance of an individual and ' genotype ' to describe the genetic makeup of an individual.
约翰逊用菜豆做实验,结果发现:如果自体受精的亲本植株来自一个混合群体,那么选择确实是有效的,而被称为"纯系"的单亲后代则表明它们在遗传上是一致的。1905年他首次采用"表现型"来描述某一个体的外观形状,用"基因型"来描述某一个体的遗传组成。
