The average contents of phosphrus in alkali feldspars in both comb zone and the first intermediate zone are high, in the range of 0.42-0.22wt%, and gradually increase from 0.21wt% to 0.50wt% as the magma evolves from the third intermediate zone to the core zone. The abnormally low content of phosphrus (<0.10wt%) in alkali feldspar from the saccharoidal albite zone is considered due to the crystallization of apatites, which gives rise to extreme depletion of phosphrus in residual melt.
阿尔泰3号伟晶岩脉梳状结构带和Ⅰ带的碱性长石具较高P含量(平均值分别为0.42wt%和0.22wt%),随着岩浆的演化进行,从Ⅲ带到核部带,碱性长石中P含量逐渐增大(平均值由0.21wt%增至0.50wt%),而Ⅱ带碱性长石中异常低的P含量(平均值为0.08wt%)是该带大量磷灰石矿物饱和结晶,导致残余熔体相中P极度亏损所造成的,而不是晚期出溶的岩浆热液交代形成的。

As for the ester exchange reaction on phosphorus, it was found that N-phosphoryl histidine the fastest one among all of the N-phosphoryl aminoacids. The results studied by MNDO method indicate that due to theparticipation of imidazole group, the formation of hexa-coordinatephosphorus intermediate made the iso-propoxyl which is opposite toimidazole group more active than the other ones and much easier to leave.When iso-propoxyl left, a new penta-coordinate phosphorus intermediate wasformed, and it is sterically favorable to be attacked by an alcohol from theopposite direction of imidazole.

Due to the complexity of the cell jitter, the NonSynchronous Tining Recovery methods are currently not mature With the emphasis being given to the Class A CBR traffic, this paper analyzes the performance of the queueing delay and cell jitter at the source node and intermediate nodes, and discusses the Source Timing Recovery at the destination node in ATM networks Firstly, this paper presents a description of the cell jitter of CBR traffic, and gives the definitions of two kinds of cell jitter regarding the Source Timing Recovery for CBR traffic Then, by using exact mathematical models and analysis methods, this paper analyzes the impact of the factors, such as the capacity of the queueing buffer, the randomness, the deterministic nature and the correlation in cell arrivals of the background traffic sources, on the queueing delay and cell jitter performance of the CBR traffic through Statistical Multiplexitng To obtain an insight into the power spectral distribution and look for better schemes for the depression and filtering of the cell jitter, within the analyses we succeed deriving the power spectrum of the cell jitter for CBR traffic Hence, not only the power spectral distribution of the cell jitter can in the frequency domain be qualitatively understood, but also can the rms (root-meansquare) value of the cell jitter be quantitatively obtained so as to more accurately measure the amplitude of the jitter In the end-to-end performance analysis of the queueing delay and cell jitter, we propose a kind of quasi-periodic cell stream model to characterize the jittered CBR traffic, and present an initial queueing analysis of the CBR traffic following such a model at a generic intermediate node Additionally, we briefly discuss the buildout/playout and Source Timing Recovery functions of the destination node Finally, regarding the Source Timing Recovery of CBR traffic, this paper systematically discusses several important principles of the cell jitter filtering and depression reported in the literature, introduces several implementation schemes of the Source Timing Recovery e.
由于信元抖动的复杂性,非同步定时恢复方法目前还很不成熟。本文针对A类CBR业务流在ATM网络源节点和中间节点的排队时延和信元抖动性能,以及在目的节点的源定时恢复问题作了较为全面的研究。首先,文中描述了CBR业务流的信元抖动,并具体地给出了两种与CBR业务源定时恢复有关的信元抖动的定义。然后,采用了精确的数学模型和分析方法,有针对性地分析了业务背景中信元到达的纯随机性、确定性和相关性以及排队缓存器容量等因素对CBR业务流经过统计复用后的排队时延和信元抖动性能的影响。为了了解信元抖动的功率频谱分布和寻求更好的抑制和滤除抖动的方法,在性能分析中,我们成功地完成了CBR业务流信元抖动的功率谱分析,使得不但可以从频域定性地认识信元抖动的能量分布特性,而且还可以定量地求出信元抖动的均方根值(rms:root-mean-square),以更为准确地衡量抖动的大小。在CBR业务流的多节点端-端排队时延和信元抖动性能分析中,我们提出了一种准周期性(quasi-periodic)信元流模型来描述感染了信元抖动的CBR业务流,并基于这一模型进行了CBR业务流中间节点的初步排队分析。

Results We discovered and confirmed that there were 17 different species of 1st intermediate host of in Paragonimus Jiangxi, covering 2 families and 3 genera, and 23 different species of 2nd intermediate host, covering 1 order, 1 family and 3 genera, 15 of which were reported to be new species by the authors. Furthermore, a new genus of Jiangxi Huananpotamon was built up, based on the assumption that Wuyi mountain range is the developing centre of Huananpotamon , and tend to spread out towards Jiulian mountain of Nanling mountain range adjacent to Guangdong Province and Luoxiao mountain range next to Hunan Province. In addition, Jiangxi Province freshwater crab order was created at the end of research, as well as a complete classification and retrieval table of its order and genus. The authors also proved that the advantageous stocks of freshwater crabs carrying encysted metacercaria of Jiangxi Paragonimus westermani were Sinopotamon fukiense and S.wanzaiense .
