With the aid of the experiment, crack formation and its expand pattern of ZTA ceramics under ultrasonic vibration were analyzed, its fracture criterion was established and the experiment results showed that intercrystalline fracture is the main fracture pattern of ZTA ceramics under common grinding, and transcrystalline fracture is the main fracture pattern of ZTA ceramics under TDUVAG, and the finding add to evidence showing that TDUVAG has better material removal property.

基于该方法分析具有预制裂纹的ZTA纳米复相陶瓷材料在超声振动条件下裂纹扩展方式，确立其断裂判据，通过该断裂模拟试验得出：沿晶断裂是普通磨削主要的断裂模式，而穿晶断裂是二维磨削主要的断裂模式，进一步证明二维磨削具有较好的材料去除特性。

Equiaxed and bigger grains are produced after C.P.Ti is deformed under the high temperature. Besides, many tiny subgrains were found in some of the metallurgical structure. The dislocation reaction caused by the deformation under the high strain rate generates ductile cellular metastructures, while the equiaxed cellular metastructures are generated under the low strain rate. The metallurgical structure of TC4 alloy including lath-shaped hexagonal martensite and trimetric martensite only exists in the higher temperature. The homogeneous, tiny and reticular grain shown after extreme high temperature deformation.

在高应变速率下变形引起的位错反应形成拉长的胞状亚结构，而低应变速率下变形则形成等轴的胞状亚结构；TC4合金在特高温变形条件下其金相组织呈网篮状，显微组织几乎全部为均匀细小的晶粒，同时出现了板条状六方马氏体；在温度尤其高的情况下还形成了斜方马氏体，变形引起的位错反应形成六方位错网络，在1200℃以下的变形易产生孪晶。

Among these three types of water locking damage, the water locking under underpressure condition has the minimal damage, the damage under overpressure condition is relatively maximal, and the damage under normal pressure is relatively medial pressure is relatively medial.

研究表明，低渗透砂岩气藏的水锁伤害具有普遍性和严重性，其中欠压作用下的水锁伤害最小，超压作用下的水锁伤害最大，常压作用下的水锁伤害居中。

The results showed that both of the chlorophyll a and total chlorophyll contents decreased under the stress of neutral salt. The changes of the chlorophyll b was not obvious and a/b not consistent. The chlorophyll a and total chlorophyll of R. pseudoacacia appeared an increasing decliningincreasing trend under the stress of mixed salt. The chlorophyll a and total chlorophyll of F. velutina increased under the stress of mixed salt. The changes of the chlorophyll b was not obvious either and a/b appeared a rising trend.

结果表明在中性盐的胁迫下，刺槐和绒毛白蜡总叶绿素和叶绿素a的含量随盐胁迫程度的增加而降低，叶绿素b的变化较小，叶绿素a/b并不呈现单一的变化趋势；在碱性盐的胁迫下，刺槐总叶绿素和叶绿素a的含量随胁迫程度的增加呈现先升高后降低再升高的趋势，绒毛白蜡总叶绿素和叶绿素a的含量随胁迫程度的增加而上升，叶绿素b的变化较小，叶绿素a/b都呈现上升的趋势。

Correlation analysis indicated that total chlorophyll contents in leaves of F. velutina and R. pseudoacacia Seedlings were negatively correlated with MDA content under both neutral salt stress and mixed salt stress. The total chlorophyll contents was positively correlated with Pro under neutral salt stress.However, the correlation was negative under mixed salt stress.

相关分析表明，两树种在中性盐和碱性盐胁迫下，总叶绿素含量与膜脂过氧化产物丙二醛含量呈负相关；中性盐胁迫下，刺槐和绒毛白蜡都与脯氨酸呈正相关，在碱性盐胁迫下则呈负相第3期武德等盐碱胁迫对刺槐和绒毛白蜡叶片叶绿素含量的影响

Results showed that:(1) soil loss from plough tillage was as much as 3~8 times that from no-tillage; the aerodynamic roughness lengths under plough and no-tillage were 0.032, 0.417, respectively.(2) No-tillage soil contained more clay and fine sand in the 0-10cm topsoil layer than the plough tillage soil. In the 0-5 and 5-10cm soil depth, the bulk density, soil hardness and soil moisture were more under no-tillage than plough tillage. Especially, the soil hardness in 0-5, 5-10 and 10-20cm under no-tillage were as much as 4.7, 2.8 and 3.8 times, respectively.
