Comparing the results which were obtained when the reagent and temperature and time varied , we found the dislocation was displayed very clearly and accurately when we etch with koh at 290 for fifteen minutes , which was the best condition 进行了不同温度、不同的试剂以及不同的腐蚀时间条件下的缺陷显示实验。发现，用熔融的koh腐蚀剂在290下腐蚀15分钟时，显示的位错最为清晰、准确，效果最佳。
These fiery conditions had to subside before molten rock could harden into a crust , before continents could form , before the dense , steamy atmosphere could pool as liquid water , and before the earth ' s first primitive life could evolve and survive 要使熔融的岩浆能够凝固成地壳、陆地能够形成、浓密大气中的蒸气能够凝结成液态水、最原始的生命能够演化与存活，在这之前，都得先让地球那炽热如火球般的状态平息下来才行。
Then the hydrogels of pva and pva - g - nipaam copolymer were made through freezing - thawing processes and the later hydrogels obtained in this method were found to exhibit obvious thermal sensitivity . in addition , the slow release of methylene blue from this kind of hydrogels was studied 采用冷冻-熔融的方法制备了pva , pva - g - nipaam凝胶，发现pva - g - nipaam凝胶具有温度敏感性，用相同方法对mb包埋固定并研究了不同温度下缓释规律。
The mafic dikes also formed by the partial melting of enriched mantle , include gabbro , diabase ( distributing mainly in luxi ) and lamprophyres ( camptovogesite , odinite and hornblende lamprophyres ) ( mainly in ludong ) . for all the rocks , crustal contamination was absent when magma emplaced . 2 基性脉岩主要包括辉长岩、辉绿岩(主要分布在鲁西地区)和煌斑岩(以斜闪煌斑岩为主，同时含部分拉辉煌斑岩和角闪煌斑岩) (主要分布在鲁东地区) ，都为富集岩石圈地幔部分熔融的产物。
The mafic rocks have high ( 87sr / 86sr ) j ( 0 . 7046 - 0 . 7077 ) and 207pb / 204pb ( 15 . 47 - 15 . 67 ) , but relatively low in ( 143nd / 144nd ) i ( 0 . 5125 - 0 . 5127 ) and 206pb / 204pb ( 18 . 26 - 18 . 52 ) . the negative correlation between 143nd / 144nd and 206pb / 204pb and the positive relationship between 87sr / 86sr - 206pb / 204pb suggest a mixing of a depleted mantle source and an em2 component in the study area . calculation reveals that the maopin - shaianjiao mafic rocks are formed by 5 - 15 % degree of partial melting of an lree - riched spinel iherzolite 模拟计算表明，该基性岩墙群是尖晶石二辉橄榄岩地幔5 - 15部分熔融的产物；微量元素配分模式及理论模拟表明茅坪?晒鞍角基性岩体的地幔源区在熔融前曾受到1俯冲沉积物熔体的源区混染和5流体交代作用。
A new structure as tapered and semi - tapered fiber is used in this method , which has the advantage of easily manufacturing , simply packing , low cost and high coupling efficiency and is based on the characters of the laser diode and the fiber mode field . the tapered structure can be made by skiving , eroding and drawing 这种方法是在充分考虑半导体激光器和光纤的特性的基础上提出的，具有加工容易、封装简单、成本低、效率高的特点，可以通过研磨、腐蚀和熔融的方法来制得。
In this section , a small organic molecule is applied to instead of pzt with the purpose to avoid the rigidity difference between cpe and pzt . ( 1 ) there is no plateau area in the conductivity curve of cpe / pzt / vgcf composite , which is due to the molecular level blending of cpe and zkf in molten condition during the preparation of cpe / zkf / vgcf composites , further verifying that pzt is conducive to the formation of conductive loop 通过对cpe / zkf / vgcf复合材料的分析探讨得出: ( 1 ) cpe / zkf脚gcf复合材料的导电曲线上并不存在类似cpe / pzt浑gcf复合材料的半导区平台，这是由于cpe亿kf / vgcf复合材料的制备是在cpe和zkf熔融的状态下的分子水平的共混，进一步证明了pzt对导电回路形成的双重作用;同时，由于zkf对vgcf的包覆作用，使cpe亿kf那gcf复合材料导电临界值较高。
