In conclusion, during the different periods after surgery, the stress distribution of bilateral condyloid processes are dissymmetrical obviously: the stress of affected condyloid process become largen more obviously than that of unaffected one, and it is the most possible in the sixth month after surgery that TMD would befallen.

本实验结论：在本实验条件下，下颌骨体部缺损游离髂骨块移植三种连接方式不同时期，双侧髁突表面应力分布不对称：患侧髁突前后斜面压拉应力明显增高且高于健侧，其中以术后6月时最明显。

It showed that deformation twins had formed in 2Cr17Mn15Ni2N and 304L targets, despite the peak pressures induced by LSP were no more than one third and half of the critical stress for twinning of corresponding targets. Different types of microbands and dislocations configurations were observed in the two targets. The features of dislocations slip deformation induced by ultrahigh strain rate followed FCC metallic crystallology. No deformation martensite phase was discovered.

结果表明，激光诱导的峰压不到2Cr17Mn15Ni2N和304L不锈钢靶材孪生应力的1/3和1/2时即有形变孪晶形成；两种奥氏体不锈钢中出现不同的显微带和位错形貌特征；高应变率加载下奥氏体不锈钢位错滑移形变符合面心立方金属晶体学关系；没有发现形变诱发马氏体相。

In order to research the influnce of provenances of Cunninghamia lanceolata on koryotype, seeds are collected from 20 different provenances , they are kept on the damp filters under the condition of 25℃ for germinating till their roots grow to 0.5cm in length.

为研究杉木地理种源对杉木核型的影响，将20个杉木产区的种子在25℃条件下发芽，当根生长到5厘米时，用8-羟基喹啉预处理，压片观察。

The results showed: at the reaction temperature of 25～30 ℃,hydrogen pressure of 1.0～1.5 MPa,Vethanol∶Vcyclopentadiene of 5～6∶1,the catalyst dosage of 4 %～5 % and stirring rate of 800 r/min.The conversion of cyclopentadiene was above 98% and the selec...

结果表明，在反应温度25-30℃，氢气分压为1.0-1.5 MPa，无水乙醇作为溶剂，V无水乙醇∶V环戊二烯为5-6∶1，催化剂用量为4%-5%，搅拌速度为800 r/min条件下，反应时间2~3 h，环戊二烯的转化率大于98%，环戊烯的选择性大于95%。

Selecting a correct honing method and pressing plate process can obtain a good oil－storage surface in cylinder bore and guarantee the bore cylindricity under the engine operating status,this r...

选择合适的珩磨方法和压板工艺，使缸孔具有较好的贮油性表面，并保证缸孔在发动机运转状态下的圆柱度，这不仅降低了缸内的机油上窜，使废气中的颗粒含量减少，而且也使缸壁具有良好的抗磨性能。

The ability of maintaining turgor pressure, osmotic adjustment,capable of preserving and endurance of water separation capability were increased under elevated CO_2 concentrations,whereas the resistance of water separation capability decreased.Theε~max increased in normal water condition of Acer truncatum under 720μmol·mol~(-1)CO_2,and cytoderm more hardness and less elasticity.But in circle 3,ε~ decreased in light and middle drought conditions and increased in serious drought condition.(5) The branch 0,branch 1 and branch 2 of hydraulic conductivity of 7 trees increased along elevated CO_2 concentration.

随着CO_2浓度的增加，RWC~0/RWC_s下降，Ψ~0π和Ψ~(100)π在循环1时先增加后下降，一直持续到循环3，高CO_2浓度下元宝枫维持膨压的能力增强，渗透调节和自身保护能力，以及忍耐脱水能力虽然增加，但是抗脱水能力却减弱了，不能同时兼得。720μmol·mol~(-1)CO_2元宝枫ε~在水分条件较好时增加，细胞壁较坚硬，弹性小，但是到循环3时，ε~在轻度干旱和中度干旱时下降，到后期水分严重胁迫时却升高。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
