Indentation is too small, the two rolls of contact pressure is small, the paper feed roller and smaller tribochemical, in the same feed rollers under tension reducing motor speed ratio; the indentation is too large, it will be closing the rubber roller and feed roll in on the PTFE contact pressure greater as a result of excessive heat, accelerated ageing of rubber roller, reducing its life.

压痕过小，则两辊的接触压力较小，送纸辊与纸张的摩擦也较小，在相同的送纸辊电动机速比下张力减小；压痕过大，则会使橡胶合压辊与送纸辊在对压运转过程中因接触压力较大产生过多的热量，加速橡胶辊的老化，减少其寿命。

The results indicated that,during MV drying,moisture distribution in wood was relatively uniform,without an obvious moisture content gradient along the direction of thickness of wood.Moisture distribution in wood was more uniform in the last period of drying.Above Fiber Saturation Point,the movement of moisture through wood was assumed to be permeable movement of free water and vapor under the action of pressure gradient;below FSP,moisture existing in vapor form in wood moved in response to a pressure gradient.Moisture transfer caused by heat diffusion and a moisture content gradient could be neglected.

研究结果表明：在微波真空干燥过程中，木材内部的含水率分布比较均匀，在厚度方向没有明显的整体性含水率梯度，特别是在干燥的后期，木材内部的含水率分布更加均匀；当含水率在纤维饱和点以上时，木材中的自由水和水蒸气在压力梯度的作用下以渗透流的形式在木材内部迁移；当含水率在FSP以下时，木材中的水分在压力梯度的作用下以水蒸气的形式向木材表面迁移；因热扩散、含水率梯度引起的水分迁移可以忽略不计。

胆系造影显示胆囊受压呈弧形。1例破裂显示巨大液平，形成&水上浮莲&征象。3例腹膜后及肠系膜包虫静脉肾盂造影显示肾盂、肾盏受压移位，积水伴弧形钙化灶。

The results of evaluation the efficiency of space disinfection by using gas-ozone in the negative pressure isolation room of hospital showed that the range of ozone concentration in the negative pressure isolation room was 0.045~5ppm during the conditions was the outlet ozone concentration 100ppm and flow rate 300LPM. According to the studies, the efficiency of space disinfection could reach 99% for more bacteria and virus under this ozone concentration.

以CFD软体模拟气相臭氧释放於负压病房内之流场，藉以评估臭氧直接空间消毒杀菌之效能，本研究设定臭氧机出口浓度100ppm (流量300LPM)，则分布於空间之臭氧浓度值范围约为0.045~5ppm，根据相关文献指出，对於大部份细菌与病毒可达到99%之消毒效率。

Results showed that the polyphenoloxidase was activated when the high pressure treatment on the pear juice was carried out under the temperature 50 ℃,the dwell time 10 min,the pH5 and the pressure between 200～300 MPa.

实验结果分析表明：在处理温度为50℃、保压时间为10min和梨汁pH值为5的条件下，200～300MPa处理梨汁时多酚氧化酶被激活，活性表现最高；500MPa时酶的活性下降到75.3%。协同温度为30℃处理梨汁时，酶的活性反而增大；30℃以后，酶活性随温度升高而迅速降低；有效协同高压处理的温度为40℃。
