坡度

The treadmill training of T-group rats were continuously trained for 4~6 weeks at the intensity of about 75% VO2max (185～24m／min,gradient of 0°,each motion lasting 50 minutes,twice a day).

运动训练组大鼠进行连续4～6wk强度约为75％VO2max18.5～24m／min，坡度为0°，每次运动50min

The treadmill training of T-group rats were continuously trained for 4~6 weeks at the intensity of about 75% VO2max (18??5～24m／min,gradient of 0°,each motion lasting 50 minutes,twice a day). Detect the content of gastrocnemius MHC mRNA by gastrocnemius reverse transcription polymerase chain reaction,and detect the changes of MHC muscle fiber and its size of cross section area through immunohistochemistry. Meanwhile,apply the electric stimulation to determine the maximal tension of isometric contraction of post-training gastrocnemius.

运动训练组大鼠进行连续4～6wk强度约为75％VO2max(18.5～24m／min，坡度为0°，每次运动50min，每天2次)的跑台训练，反转录聚合酶链式反应腓肠肌MHC mRNA含量，以免疫组化方法检测肌球蛋白肌纤维的改变情况及横截面积的大小，同时运用电刺激观察训练后腓肠肌等长收缩最大张力。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.
