seed crystal 籽晶;晶種。

seed dressing

The process of growing ktp crystal of high quality and low conductivity was studied . it was pointed out that many factors such as the uniformity of temperature distribution in the furnace , the accuracy of temperature control , the quality and direction of seed crystal and the speed of temperature drop all had an important influence on the quality of ktp crystal 研究了生長高光學質量、低電導率ktp晶體的工藝過程,指出晶體生長爐溫度場的均勻性、控溫精度、籽晶的質量和定向以及降溫速度的快慢對晶體的光學質量有著重要的影響。

The experimental results show that the cycle of the mother liquid increases the yield of the product , the seed crystal can improve long - diameter ratio remarkably , the proper additive reduces the speed of crystal growth and make size distribution homogenize . through appending different seed crystal and bivalent lead at one time , we may receive when the content of the seed crystal is 0 . 075 % and pb2 + is 20 - 50ppm , the yield of the basic magnesium chloride whisker is high and crystal shape is good . the surface active agent can improve dispersion performance of the basic magnesium chloride whisker 研究結果表明:母液循環可以提高堿式氯化鎂晶須的產率;添加晶種可明顯的改善晶形;合適的添加劑可以降低晶體生長速度并可提高晶須的粒徑分布;而同時加入不同用量的晶種和pb ~ ( 2 + ) ,試驗結果表明晶種含量在0 . 075 , pb ~ ( 2 + )在20 50ppm時,晶須的產率高,晶形好;表面活性劑對產品的分散性能有所改進。

The topic is on the basis of the synthesis of the basic magnesium chloride whisker . the research perform the recycling experiment on the synthesis and property of the basic magnesium chloride whisker by adding ammonia or magnesium chloride and ammonia simultaneously into the mother liquid of crystal and during the synthesization of the basic magnesium chloride whisker , we add the seed crystal , additive , or surfactant in order to increase the yield of crystal 在課題組已成功合成堿式氯化鎂晶須的基礎上,為提高堿式氯化鎂晶須的產率,進行了在結晶母液中補加氨水或同時加入氨水和氯化鎂的循環試驗,并進行了在合成堿式氯化鎂結晶過程中加入添加劑、晶種和表面活性劑試驗,研究對堿式氯化鎂晶須合成及性能的影響。

Another theory is based on the notion of ' seed crystals ' in which the knowledge and story of lemuria was encoded and stored in seed crystals just before lemuria fell 另一個理論是建立在“種子水晶”的基礎之上,利莫里亞的知識和故事被編入在利莫里亞沉沒之前被編入和貯存在種子水晶里面。

Seed crystals are both physical and part of our genetic encoded crystaline make - up 種子水晶是組成我們的物質身體和部分遺傳基因密碼的水晶能量線。
