解釋
和根源特質-
Comparison of the characteristic parameters of immobile elements, such as ree, sc, th, ti etc and of the characteristics of sedimentology and mineralogy comes to a conclusion that the provenance of the sediment is different in the last glacial maximum and in the sub - interglacial stage, and they have the traits of mixed source. during the last glacial maximum the sediment in the outshelf of the southern east china sea was affected weakly by changjiang river and they are probably derived from the coast mountains of zhejiang - fujian province, which are near the southern east china sea
通過對東海外陸架樣品的稀土元素和sc ， th ， ti等不活潑元素地球化學物源示蹤指標對比，再結合沉積學和礦物學特徵，判斷末次盛冰期與盛冰期以前的沉積物具有不同的物質來源，不同時期的沉積物都具有混合物源的性質，盛冰期東海南部外陸架沉積物受長江物源影響較小，可能來源於距東海南部較近的浙閩沿海山地。 -
Using the traits of arc adjust itself of the co _ 2 welding, adopting slow - descending feature or even feature of electrical source equipping with system that delivering the welding rod at the invariable speed, then, the arc burning steadily is realized, and the quality of welding is improved
利用co _ 2氣體保護焊電弧的自身調節特性，採用緩降或平硬特性的電源配等速送絲系統，通過改變電源空載電壓來調節電弧電壓，再利用電弧電壓和熔化速度之間的關系調節焊絲熔化速度使之等於送絲速度，最終實現電弧的穩定燃燒。 -
I designed both hardware and software to develop the multi - channel analyzer, of which the key is the pc / 104 embedded computer. in a word, it has five traits as follows : ( 1 ) the key of apparatus is the pc / 104 embedded computer ; ( 2 ) on the hardware, we introduce the high - speed a / d conversion component - max191 to improve the mca ' s conversion speed and meet the demand on the spot ; ( 3 ) adopting high frequency module of electrical source to reduce its volume. ( 4 ) the mca consumes low power no more than 3. 9 watt
以國土資源部項目為依託，以pc 104嵌入式微機為平臺，完成了小型、低功耗能譜採集系統，特點是： （ 1 ）以pc 104嵌入式微機為平臺，實現了採集系統微機化； （ 2 ）採用高速低功耗a d器件maxl91 ，與現有的mca相比，提高了轉換速度，降低了mca的功耗； （ 3 ）採用高頻模塊電源，減小了採集系統的體積； （ 4 ）整機功耗低，小於3 . 9w ； （ 5 ）儀器重量輕。 -
This paper is a part of national natural science fund item - summer cooling and winter heating dynamic traits research of underground energy - keeping system the house in summer cooling and winter heating area, mainly task is the experimental research of ground source heat pump systems with horizontal buried pipes
本文為國家自然科學基金資助項目「夏熱冬冷地區住宅地下蓄能系統冷熱聯供動態特性研究」的一部分，主要任務是地下水平埋管換熱器地熱源熱泵系統冬夏暖冷聯供實驗研究。 -
Then the paper not only puts forward the principal, also develops dynamic index system according to the character of project phases and the risk traits, risk source, risk distributing in every phases. the index system also is based on the set of risk factors including the factors that study by others. after this, the paper analyses the advantages and application confine of every the discrimination method, then make good use of matter element analysis and assembled appraisal method in project termination decision. real application shows that the model is very useful and effective
依據研究與開發項目的分階段特性和風險特點、風險來源、風險分佈規律，結合國內外研究的指標因素集，提出了建立指標體系的原則和架構並建立了分階段較為系統的指標體系，在分析了國內外中止決策判別方法的優缺點和適用范圍的基礎上，將可拓理論和組合評價方法用於項目中止決策判別，通過實例分析證明了所建模型的有效性。
