This may be possible by observing porphyroblast formation in cleavages of known deformation age, by identifying metamorphic mineral assemblages created by different events, or via geochronology.

这有可能通过观察斑晶形成的分裂已知变形年龄，查明变质矿物组合所造成的不同的事件，或透过年代。

Structure: The structure of Jade variable phenocryst interwoven structure, refers to its metamorphism, the transparent and granular around the porphyroblast small fibrous mineral crystals formed interwoven structure.

结构：翡翠的结构为变斑晶交织结构，系指其在变质作用下，透明粒状斑晶的周围的细小纤维状的矿物晶体交织在一起而形成的结构。

The intersection of the subvertical foliation adjacent to the porphyroblast rim with an earlier or la ter formed shallowly dipping foliation, which is trapped in the porphyroblast du ring later growth, defines the FIA orientation, and is independent of the moveme nt direction on this foliation.

非洲板块与欧洲板块的相对运动方向和在阿尔卑斯造山作用期间形成的变质产物所指示的运动方向相互一致的事实强有力地表明：FIA是由一种反映板块相对运动的机制形成的。

Formation of augen fabrics is decided by the ductile deference between the porphyroblast and matrix in deformation rock.

长石眼球构造的形成主要是由长石与石英的韧性差决定的，塑性变形首先从斑晶的周围部分开始，逐渐向斑晶发展，脆性残斑核不断减小，这与剪切带内糜棱岩化强度分带相一致。

Consequently, they continued to grow and connected with each other to form the skeletal crystal for the porphyroblast.

本区石榴石、十字石等变斑晶的生长过程有多种形式，多数单晶不是一开始就环绕一个晶核不断增长，而是以多结晶中心聚集生长为特征。

Applying the theory of deformation partitioning to this area, the author discuss the relationship between deformation and porphyroblast growth, and get the conclusion of the sequence of deformation and metamorphism. At the first time we measure the distribution of chemical composition within the porphyroblast by XRF and confirm the theory of deformation partitioning quantitative.

利用宝音图群泥质变质岩中的存在大量变斑晶矿物，应用变形分解理论，讨论了变斑晶生长和变形关系，确定了变质变形演化序列，提出了变斑晶的生长相，并首次利用同步辐射XRF技术测定了变斑晶矿物的化学成分分布，主要是微区的微量元素成分分布，定量地证实了变斑晶矿物生长相的存在，进而讨论了与变形关系，并进行了变斑晶矿物不同生长相的温压计算。

The measurement methods of WK include the way of veins and fibers,the rotated porphyroblast approach,the method based on the relation between quartz C axis fabrics and strain ratio,the method based on the relation between oblique grain shape and quartz C axis fabrics,and the method of ultimate Mohr circle.

文章介绍了涡度的具体测量方法，即张裂脉中纤维法、旋转残斑法、石英C轴组构与主应变比值的方法、石英C轴组构与斜列颗粒形态的方法等。

F oliations forming subvertically against the porphyroblast margins have a wider r ange of orientations in the matrix because they can be rotated or destroyed by t he effects of reactivation of earlier formed foliations.

这种情况要求：后来的每一代褶皱都是由于渐进的、总体不均匀缩短作用造成的，这种情况表明：FIA保存着原始的运动方向，此方向未因以后的变形而转动。

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。
