断裂的

Under the action of the active faults stretched deeply to magma chambers,the mantle gas released directly from the magma chambers by taking the faults as the paths is characterized by the CO2／3He ratios of 107～109 which are lower than the ones of the original mantle gas just separated from basalt magma.

我国五大莲池、云南腾冲、吉林长白等火山活动区温泉释放的幔源气体CO2／3He比率受到幔源气体释放机制的控制，在深切岩浆房的断裂活动作用下，以断裂为通道直接自岩浆房中释放的幔源气体，以低于幔源气体脱离岩浆时的CO2／3He比率为特征，其比率为 107～109。

The analysis indicates the following: the fault activity rate is the most representative parameter;the fault activities in the Huimin subbasin have the long-continued,differential and episodic characteristics;and the activities of faults of lower orde...

结果表明，凹陷内断裂活动具有长期性、差异性和幕式性的复杂特征，低级次断裂活动具有短期性和不确定性的特点。四级控凹断层分别对凹陷的形成和凹陷内局部构造起着不同的作用。

Results: The profiles of split trace of 40 bone fossil samples respectively from Stegodon orientalis, Chinese rhinoceros, Cervus and other mammalian fauna were identified, some of them were found blunt and might be rodent bite marks.

结果 经40件东方剑齿象、中国犀、鹿等残骨化石标本断裂痕迹剖面的观测，发现有部分骨化石断裂剖面圆钝，似啮齿动物的咬痕，但大部分骨化石断端剖面呈锥形切削改造，有的双面削刮呈锐利器型，有的存在明显打击或铲刮的&印记&，初步认为属早期人类制作骨器的遗迹。

The mechanism of the fracture of radially oriented toriods of sintered SmCo_5has been investigated. It showed that the fracture of radially oriented toroids af-ter sintering may be caused by wild anisotropy of thermal expansion.

研究SmCo_5辐向取向烧结环体的断裂机制指出：SmCo_5的强烈各向异性的热膨胀性质决定了辐向环在烧结后的断裂。

The tensile properties of composite yarns mainly depend on the tensile properties of filament, and their tenacity is higher than that of two-fold Wool/PET staple fiber yarns. The difference of the tenacity and breaking extension between Sirofil and Plyfil composite yarns is not significant.

与传统短纤维合股线相比，毛涤复合纱线的强伸特性主要取决于长丝的强伸特性，复合纱线的断裂强度大于毛涤短纤合股线的断裂强度；Sirofil复合纱与Plyfil复合线的强伸特性无显著性差异。

Degradation products were investigated by Fourier transform infrared spectroscopy and its molecular weight was measured by the viscosity method. The results show that the mechanism of photolysis and hydrolysis of PLA is the same with the breakage of ester bond at random.

结果表明：PLA在紫外光解下的降解同水解一样都是酯键断裂导致的，并且是酯键的任意断裂；紫外光降解过程中，黏均相对分子质量的下降趋势先快后慢，并且PLA起始浓度越小越有利于降解。

Spring fatigue strength is a key performance index. Fatigue strength is less than static stress strength such as elasticity limit,yield strength.

弹簧由于承受交变应力的作用，在运行过程中发生的弹簧断裂主要是疲劳断裂，所以，弹簧的疲劳强度是关键的性能指标。

It is found that the electric, field improves elongations in 2090 and 2090+Ce alloys markedly, especially in 2090 alloy, but has little effect on strengths. At the same time, the electric field lessenes percentages of intergranular delamination and increases transgranular fracture and microscopic plastic deformation.

研究表明：固溶电场可显著提高2090合金及2090+Ce合金的延伸率，尤其是对2090合金，但对强度则无明显的影响；同时，固溶电场减少合金的沿晶分层断裂比例，并增加穿晶断裂及微区塑性变形；固溶电场还使合金时效后δ′相颗粒的平均尺寸减小、尺寸分布范围减小，并使PFZ的宽度减小。

In this paper, some improvements have been made on the traditional gradient interpretation methods for the two-dimensional fault gravity anomalies:① The least squares fitting technique is adopted to figure out the dip angleαof the step;② The dip angle and the horizontal boundary of the step are directly used to calculate the burial depth of the step;③ the interpretation method for gravity two-dimensional gradient is extended to the interpretation of the complex fault model.

摘要对以往的二维断裂重力异常的梯度解释方法作了几点改进：①采用最小二乘拟合方法求取台阶倾角α；②直接利用台阶倾角与台阶的水平边界位置来计算台阶的埋深；③将重力二维梯度解释方法推广到复杂断裂模型的解释。

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。
