  3. Negative acceleration phase

    負性加速期
  4. After 1989, the increase of demand slowed down and facing the complexion of low degree of industrial concentration of product market and financial strain of medi um and small - sized enterprises caused by the circulating trap of " credit squeeze - - - bad loan ", the advantageous enterprises " " wallow in money ", specifically, those listed companies that could finance from the stock market, began to take predatory pricing strategy in succession and tried to enlarge market share and obtain high return by squeezing medium and small - sized enterprises out of the market after 1998, the vicious circle of deflation and " credit grudging " of banks in product and credit markets, overcapacity, the difficulty of retreating of loss - incurring enterprises in some industries from the market for institutional reasons and over - competition in some industries, led to the incessant decrease of enterprises " global income, persistent increase of rate of debts and constant rise of ratio of bad assets of banks, which further intensified the vicious circle of deflation and " credit grudging " of banks

    如在改革開放初期，在產品市場需求旺盛和信貸市場預算軟約束的情況下，各類企業的最優決策就是採用高負債、高擴張的「負債的有限責任效應」策略來搶占市場並獲得高回報； 1989年以後，需求增速開始放緩，面臨產品市場產業集中度較低和信貸市場「信貸緊縮-不良貸款」循環陷阱導致的中小企業資金緊張的局面， 「錢袋鼓鼓」的優勢企業（尤其是那些可以通過股票市場融通資金的上市公司）紛紛採用掠奪性定價策略，試圖通過把中小企業擠出市場來擴大市場份額並獲得高收益； 1998年以後，產品市場和信貸市場形成了通貨緊縮和銀行「惜貸」惡性循環的狀況。產品市場上部分行業生產能力嚴重過剩，且由於體制等原因導致虧損企業無法退出，因此這些行業中出現了過度競爭的現象，企業總體收益的不斷下滑、負債率不斷提高以及銀行不良資產率的持續上升，又進一步加強了通貨緊縮和銀行「惜貸」的惡性循環。
  5. ( 2 ) because of t he variability of rock subjected to outside action, three new conceptions : postive damage basic damage and negative damage, are suggested, which can deal with the condition that rock density became large. ( 3 ) the present damage variables based on ct number mostly include ct average number of the rock without damage, which is difficult to measure, so a new damage variable, which includes the average ct number is proposed, on the other hand, strain equal theory is generalized because the one put foreword by lemaitre is not good enough to use. ( 4 ) a axial damage constitutive equation is proposed and testified. ( 5 ) with the circle times, the damage propagation laws of two different rocks, subjected to circle of freezing and thawing, are studied, and in the analysis process, traditional analysis method including average ct number and is used, some important conclusions are reached : inner damage of soft rock containing a large mount of apertures is largely propagating with the time increasement of circle, however, at the preliminary time, the hard rock containing a small mount of aperture is a little propagating, at late time, the influence become large ; ( 6 ) zone separation and statistics frequency put forward is used to analysized the three different damage propagation in the open circumstance, when they are subjected to the different circle times of freezing and thawing, in which the temperature variability is linear, different freezing rate, and different freezing temperature, and no water is supplied during the test

    在研究過程中本文主要做了以下工作： （ 1 ）針對巖石損傷變化較小時，運用ct均值和方差分析不方便的缺陷，本文提出運用對ct數范圍劃分區段的方法，根據各區段統計頻率的變化規律來分析損傷擴展狀況； （ 2 ）針對巖石受到外部作用的多變性，本文提出了基準損傷，正損傷，負損傷的概念，在某種程度上考慮了巖石受到外部作用時的壓密情況； （ 3 ）現有的基於ct數的損傷變量大多需要用到巖石基體的ct均值，這實際上是很難觀測到的，因此本文建議了一個可運用巖石初始狀態ct均值的損傷變量，由於現有的勒邁特教授應變等價原理使用上的不便，本文在其基礎上進行了推廣； （ 4 ）建議了一個可用巖石初始狀態ct數和彈性模量的單軸損傷本構方程，並用算例進行了驗證； （ 5 ）對兩種不同巖石在開放環境下受到凍融循環作用且融化過程中補水時，內部損傷隨凍融循環次數增加的擴展規律進行了探討，主要運用了常規的ct均值和ct方差的分析方法進行分析，試驗發現：對于孔隙率和含水率較高，密度和強度較低的軟弱巖石，凍融循環次數對損傷結構的擴展有明顯的影響，而對于孔隙率和含水率較低，密度和強度較高的硬巖，凍融循環次數對其損傷結構擴展初期由於含水率低的原因，影響不是太大，而後期由於水補給后，含水率較高的原因，凍融影響逐漸增大； （ 6 ）運用了本文提出的區段劃分和統計頻率的方法，深入地分析了開放環境下的線性溫度變化的凍融循環次數，凍結溫度，凍結速度不同巖石作用時，其內部損傷隨凍融循環次數，凍結速度和凍結溫度變化的擴展規律，需要指出的是除了在試驗前飽水外，凍融過程中沒有補水。
  6. This system has a lot of the prominent characteristics such as simple structure, and good efficiency, especially adapting to the large, middle power machine equipments that have the big qualities, periodicity, in the short time, constantly accelerating and applying the brake. it is very remarkable in energy - saving

    二次調節靜液傳動系統具有許多顯著的優點，比如：較為簡單的結構，並可得到較高的效率，特別適用於那些負載質量較大、具有周期性、在短時內需不斷加速和制動的大中功率場合（如車輛系統和升降系統） ，其節能效果十分顯著。
