The authors believe that the diversification of rock zonation and lithology of these high pressure rocks can be attributed to the metasomatism that took place between deep melt and ultrabasic rocks in the subduction zone, and thus propose a hypothesis of subduction melt metasomatism to explain jadeite formation.
笔者认为俯冲带中形成的深部熔体与超基性岩之间的交代变质是导致岩石分带和岩性多样化的根本原因,提出了俯冲带熔体交代成因说,认为俯冲带、深部流体和超基性岩体是形成翡翠及其过渡品种的3个必要条件,并因此指出在人工合成过程中引入流体相很可能是降低实验条件的苛刻程度、从而合成出真正具有商业意义的翡翠的途径。

The citric acid-producing strain Aspergillus niger 2363-2, was isolated and used in our research. The fermentation conditions were optimized as follows: sucrose as carbon source 8. 0-14. 0%, ammonium chloride as nitrogen source 3. 0-4. 0g/l, initial pH 2. 0, and cultural temperature 30℃. The influential factors of formation of spores were also studied, and a series of measures were taken to restrain the spore formation on the basis of our experimental results. With the consideration of the cultural environment and microbial cell itself, the factors affecting the duration of citric acid-producing activity of microbial cells were examined, and it is found that undissociated citric acid and the ageing of microbial cells are the main factors. The experimental results also show that partial replacement of fermentation broth can lengthen the duration of citric acid -producing acitivity of microbial cells.
筛选出了用于试验研究的柠檬酸发酵用菌Aspergillus niger 2363-2,确定了其最适发酵条件—碳源选用蔗糖,浓度8.0~14.0%,氮源为NH〓Cl,浓度3.0~4.0g/l,发酵初始pH值为2.0,培养温度30℃;讨论了分生孢子产生的影响因素,并通过试验提出了抑制分生孢子产生的措施;从分析微生物所处的环境和微生物本身两个方面出发,探讨了影响微生物菌体产酸活性持久性的因素,认为分子态柠檬酸和菌体本身的老化是影响微生物产酸活性持久性的两个主要因素,并提出采用部分置换发酵液发酵能延长微生物菌体的产酸活性。

It is more conservative with screen handling and thus does not screw up the screen as easily as more or less. p uses its own termcap package with TERMPATH support that makes it easy to have a local .termcap file in the user's home directory to override bad termcap entries. p supports three text attributes for nroff: bold, italic, and bold-italic. p is able to find patterns in higlighted text. p also filters out unprintable characters.
它在屏幕处理上是更保守的,这样就不会轻易地把屏幕弄得一团糟。p使用它自己的带有TERMPATH支持的termcap包,这可以方便地用用户主目录中的本地。termcap文件覆盖坏的termcap条目。p支持nroff的三个文本属性:粗体、斜体、和粗-斜体。p能在突出选中的文本中发现图案,也可以过滤出非打印字符。
