PICC is of higher performance than PLC, it can more easily solve the problem of sampling bed thickness and the control of electro-magnetic valves and so on in jig automation, buoyage displacement sensor can be sublimated to a complex sensor by means of the dynamic analyze of buoyage displacement signal.

可编程智能卡在过程控制中具有比PLC优越的性能，在跳汰自动化的应用中可更方便地实现床层厚度的采样与电磁风阀控制等工作，通过对浮标位移信号的动态分析可将浮标位移传感器升华为一个可感知多个参数的复合传感器。

And considering the necessity of avoiding blow-up and frost boil, some available measures, such as mat base of calking crushed rock, anti-freeze and seepage prevention insulated wall are adopted in practical roads.

考虑到防止冻胀、翻浆的必要性，提出了填隙碎石垫层、防冻防渗保温墙等有效的路基防病害技术措施，并在具体工程中得到应用。

When we started to manufacture in this way last year we knew we had a solution to the text / cover problem, The laminate applied is very thin and only adds 15 micron to the original stock calliper, the feel of the paper changes very little" he added "the sheets were supplied from stock, this combined with our production methods meant the whole job was turned around in 2 days.

当我们开始生产这种方式去年我们知道我们有一个解决方案文/覆盖问题，该层压应用非常少，并且只增加了15微米到原来的股票卡尺，纸张的感觉变化不大"，他补充说："床单是股票供应，这与我们的生产方法相结合意味着整个工作是在2天内关闭围绕。

According to the principle of strontium isotope stratigraphy, we attempt to determine the age of the boundaries for Campanian/Santonian and Maastrichtian/Campanian by 87Sr/86Sr ratios for Gamba section in southern Tibet.

在与国际上同期海相地层锶同位素演化曲线对比的基础上，研究了晚白垩世海相碳酸盐锶同位素组成与主要地质事件的关系；在将本研究锶同位素数据融入到全球中新代海水锶同位素曲线的基础上，综合作出了中新生代海平面变化和锶同位素对照曲线，讨论了全球风化速率，造山事件，气候，海平面变化以及灾变性事件对中新生代海水锶同位素的控制作用；根据锶同位素地层学原理，本研究尝试将碳酸盐锶同位素组成用于海相地层定年上，利用已有的全球海水87Sr/86Sr值-年龄数据库和测试的藏南晚白垩海相碳酸盐的87Sr/86Sr值，确定了岗巴剖面Campanian/Santonian和Maastrichtian/Campanian阶界线，标定了广泛分布于白垩纪的厚壳蛤化石的年龄；本研究还将这些方法推广到了塔里木盆地井下奥陶纪地层的年龄标定，确定了中/上，中/下奥陶统界线，从锶同位素角度获得了古岩溶作用证据，显示锶同位素地层学在解决海相地层对比，年龄确定及在岩溶型油气储层研究中的潜在价值和良好应用前景。

The results showed that there was no significant difference in three structure approach of liquid layers among which B was relatively higher;and it was considered that one-step dilution was an effective preservation method in that survival capacity with frozen and melted embryos freshly split,and survival capacity of frozen and melted IVF embryos split by one-step dilution by application minimum capacity refrigerant method with specific canaliculus were obviously higher than B.

结果，3种不同液体层构成间胚胎的存活能力无显著差异，B法较高；应用特定细管最小容量冷却法在冷冻溶解的新鲜分割胚、体外受精分割胚及冷冻溶解的体外受精分割胚一步法稀释后的存活能力均显著高于B法。结果表明，特定细管最小容量冷却法是更有效的保存方法。
