I seriously fried the small battery holder I was using for the reversing battery and melted one of my oscilloscope probes on the very hot reversing FET when fiddling with the oscillator circuit so I decided to make the output stage absolutely unable to go into forward and reverse at the same time by putting the two opto isolators back to back from one chopper amplifier to the other so only one of them can ever be on at a time - gets rid of some parts and adds a major safety improvement - bonus!

i认真油炸小电池匣，我使用为扭转电池和融化我的一个示波器探头就非常热扭转场效应管时，fiddling与振荡电路，所以我决定使输出的阶段，绝对无法进入正向和反向在同一时间，把两个光电隔离器背靠背从一菜刀放大器到其他，所以只有一个人能永远就在一个时间-摆脱部分，并增加了一个重大安全改善-奖金！

Results Nine days after ulcer induction, the ulcer area was 11.9±3.1mm^2 and 19.7±3.8mm^2 in rats with normal saline and celecoxib treatments, respectively (P.01). The total acidity of gastric juice and the expressions of H(superscript +), K(superscript +)-ATPase mRNA and protein in celecoxib group were significantly higher than that in normal saline group at both 6 and 9 days after ulcer induction, but no significant difference was found between the two groups in the amount of secretary canaliculus and microvillus.

结果 制模术后第9日，生理盐水组和塞来昔布组的溃疡面积分别为11.9±3.1和19.7±3.8(P.01)；制模术后第6日和第9日，塞来昔布组胃液总酸度和H，K-ATP酶mRNA和蛋白表达水平均显著高于生理盐水组，而两组壁细胞的分泌小管和微绒毛数量则均无明显差异。

Then we found out that capillarity pump can save more energy and has simpler structure by analyzing the three measures, so we decided to use the capillarity pump. Finally we designed three different capillarity pumps on a liquid-vapor heat exchanger to do experiments. From the experimental data, we have concluded that this method is useful and practical.

接着根据系统工质和系统的条件，在实验中采用了两种毛细芯管芯，即组合铜丝网与分子筛管芯，然后我们制作了一个汽液热交换器，在一台风冷热泵冷水机组建立了试验台，并进行了相应的试验，通过试验可知该改进具有实际意义和应用前景。
