The origin and evolution of land plants was an important event in the history of earth life and has affected all other lives on the earth and global environment. during the past two decade, the new discoveries of fossil plants microfossils and megafossils from the mid - ordovician through all silurian to the lower devonian improved knowledge of the origin of land plants, provided a time framework of the basal groups for the land plants and the early evolution diversity of vascular plants. three new plant based epochs have been recognized. on the other hand, molecular sequence studies have provided insights into the phylogeny and early branches of land plants. a phylogenetic tree has been established by the joint of a study of comparative morphology and gene sequences. this paper summarizes recent advances and new knowledges, comments on the phylogenetic studies based on the cladistic analysis
陸生植物的起源和演化是地球生命中的重大事件，它影響到地球上所有的其他生命和全球環境。在過去的20年中，從中奧陶世歷經整個志留紀至早泥盆世的巖層中，化石植物微化石和大化石的新發現改變了人們對陸生植物起源的認識，並且為陸生植物和維管植物早期演化分異提供了基部類群分化的時間框架。據此人們識別出地史中的3個陸生植物的時代：始胚植物時代始維管植物時代和真維管植物時代。 -
Fluid noise mainly comes from out put pulsation of rate of flow, the main reason of out put pulsation of rate of flow is the instant high pressure return flow that obturation cubage produced when the big round curve pressure transition. the v trough on the port plate can reduce the fluid noise. in this paper, the author based on the acting of dam a river and condensability of liquid and used matlab language as tool to calculate the v trough on the original port plate and drew out the p - t diagrammatic curve and analyzed its shortcoming and improved the design of original v trough and got that the best size of its angle was 12. 3 and its length was 5mm and the cross section was an equilateral triangle
流體噪聲主要來源於輸出流量脈動，造成輸出流量脈動的主要原因是閉死容積在大圓弧段壓力切換時產生的瞬時高壓迴流，在配流盤上開設v型尖槽可降低因高壓迴流而引起的流體噪聲，本文以截流作用和液體的可壓縮性為理論依據，以matlab語言為工具，對原配流盤上的v型尖槽進行了理論計算，繪制出p - t圖線，分析了它的不足，並對原有v型尖槽進行了優化設計，得出了v型尖槽的最佳幾何尺寸：配流盤平面上的v型尖槽的兩邊的夾角為12 . 3 ，槽長5mm ，槽的橫截面為等邊三角形。 -

The result of this paper were : 1 ) the market mircrostructure of chinese stock is ' nt market maker, two - part stock can n ' t circulate and the scale of current stock is small, so, filling right effect make dividend event do n ' t diluate the price, the stock price could n ' t reach optimal price ; 2 ) the meanings of bid - ask speed in chinese has been changed, did n ' t reflect the real trade cost, only reflect the possible trade cost, contained desire of price popple, din n ' t belong absolute liquidity again ; 3 ) turnover rate is a liquidity ' s index, speculation ' s index too, which can explain one side of liquidity, but this index is defective in chinese stock market ; 4 ) martin index was decrescent when dividend event occurred, display the liquidity of stock was improved, so, the martin index is compatible index to measure chinese stock liquidity ; 5 ) stock dividend event affect the liquidity in the stock dividend day, stock dividend event can n ' t dividend event in the bulletin day ; 6 ) the quantity stock dividend and trend of stock market was significant factors that affect the liquidity
本研究的結論是： 1 ）中國股票市場的微觀交易結構並不是採取做市商制度，且2 3的股票不能流通，流通股規模很小，存在著股票股利事件后的快速「填權」效應，使股票價格快速回升，股票股利發放事件的稀釋價格作用無法發揮，也就無法達到「最適價格」 ； 2 ）中國股市的買賣價差的含義發生了變化，不再是實際交易成本的反映，只是可能交易成本的反映，因而很大程度上代表了股價的波動意願，並不具有完全意義上的流動性含義。 3 ）就換手率而言，它既是流動性的衡量指標，也是最常用的衡量投機性的指標。換手率指標只能說明流動性的一個側面，在中國衡量流動性是有缺陷的。 -
