Ericsson cycle provides the maximum efficiency at a certain temperature ratio, and the performance of any other thermodynamic cycle can be got by revising the performance of Ericsson cycle with component-perfection coefficients and cycleperfection coefficient.

该公式有很强的功能，可以估算循环的热效率、比功、水气比、极限效率、各设备性能对循环性能的影响以及采用再热手段后循环的性能，而且具有很高的精度，热效率与精确计算相比相对误差在0.5％以内。

Measurement system for crystal fiber loss has been set up, an idea that single mode quartz fiber acts as the coupler of crystal fiber incident light has been put forward. The propagation loss of the cladded crystal fiber is measured using this measurement system to be 14 times as low as that of the uncladded crystal fiber, and the transmission of low order modes has been realized in the cladded crystal fiber.

利用激光加热基座法生长出了不同直径、不同晶向的LiNbO〓和Nd：MgO：LiNbO〓单晶光纤；根据熔区质量守恒和热量守恒方程解析了生长速度、速度比和激光功率对晶纤内部显微缺陷和直径波动的影响，提出通过控制激光功率和速度比来维持熔区形状的稳定，以实现高品质晶纤的稳定生长。

The research of convectors final slag properties indicates that, the content of MgO in final slag, in top blown, is lower than that in bottom blown, and the content of TFe in former is higher than that in latter, and as the content of MgO in slag increased, the melting point of slag increase, significantly.

转炉终渣性能分析研究表明，顶吹终渣MgO的含量比复吹终渣含量低，顶吹终渣中的TFe含量比复吹终渣的含量高；随着渣中MgO含量的增加，渣的熔点显著增大。

E. , approximately four months; 2 the active periods occur much longer than the non-active periods; the main climatic characteristics of the non-active periods, compared with the active periods, is weaker monsoon with westerlies at 850-hPa and easterlies at 200-hPa on the deviation fields of circulations over the SCS (active time minus non-active time); it is warmer in the active periods than in the non-active periods at lower and upper levels; 3 in most circumstances, the low frequency vibrations of the summer monsoon and its rainfall are quite in phase.

2其中活跃期出现时间要比非活跃期长的多。与活跃期相比非活跃期主要气候特征表现为季风的减弱，在环流的偏差场上在南海上空850hPa上为西风，200hPa上为东风，活跃期高低空都比非活跃期要暖一些。(3)在多数情况下夏季风和夏季风降水的30-60天的低频振荡比较一致。

Facts have proved that the pork fat are higher than all of the meat, while the protein is lower than all of the meat, so do not eat pork on the human body was okay.

事实证明，猪肉的脂肪比肉都较高，而蛋白质比肉类所有较低，所以不要吃对人体的猪肉还不错。

Just as "no more than one mountain, there is no way longer than the foot," on the road at the foot of our own destiny in our own hands.

It is showed that the propping fracture conductivity of gas log is 1.5 to 2.5 times higher than that of liquid log under the same testing conditions (such as haydite type, sanding concentration, temperature and pressure). A lower average sanding concentration in gas well fracturing should be adopted than that in oil well fracturing so as to obtain the same propping fracture conductivity.

结果显示，在相同实验条件下（陶粒类型、铺砂浓度、实验温度和压力），气测导流能力值比液测值高1.5~2.5倍，表明要获得相同的支撑裂缝导流能力，气井压裂中的铺砂浓度应比油藏低。
