Creep analysis methods of high - rise buildings and large span buildings can only refer to creep coefficient method in bridge engineering or the method of degree of creep in hydraulic construction engineering under the present experiment conditions. in this paper, the incremental expressions of concrete creep and shrinkage strain when the initial computational age is not the same as the loading age are derived and corrected from the concept of concrete creep coefficient and the mean value theorem of integral and the principle of superposition. the differences of efficiency and accuracy of creep analysis between the finite element method with creep coefficient and the initial stress method with degree of creep are presented. this paper suggests that engineers should use the initial stress method with degree of creep to estimate the influences of creep on high - rise buildings and large span buildings on the basis of conceptual design

The present article understands that the improvement of the civil regime relies on insistence of the following principles : ( l ) the assurance of judicial justice, as to realize the axiological objective of the regime ; ( 2 ) proportional intervention, on interfering illicit civil activities, proportionality should be considered ; ( 3 ) procedural effectiviness, to achieve the maximum litigation effect with the minimum litigation cost specially for the cases in which technical defects are found, but in the mean time, common interest are not prejudiced, the promotion of civil protest may lead to an expenditure much higher than the litigation value, therefore, civil protest authority should not promote the civil protest
維護司法公正原則，是完善民事抗訴制度的重要原則之一，體現了制定這項制度的目的；適度干預原則在強調對違法民事行為進行干預的同時，指出這種干預應是適度的。抗訴的適度性體現在兩個方面：一是尊重當事人的處分權，二是維護法院裁判的既判力。訴訟效益原則指出，民事抗訴制度應以最少量的訴訟投入獲得最優化的訴訟效果，對于那些雖在技術上存在不足或缺憾之處但不損害公益的生效裁判，若提出抗訴可能導致人力物力的支出比裁判所涉及的訴訟標的額更大或造成當事人的無端訟累，抗訴機關不宜提出抗訴。 -
It also studies the problem of real option pricing when the underlying assets follow the pure jump poisson, mixed jump - diffusion merton and mean - reversion model, and obtains the price formula or partial differential equation to price and hedge the real option. when the value of real option can not separate from the value of project, or the uncertainties are endogenous to real option holder, it is difficult to pricing the real option by the ways of no - arbitrage. in this paper we present a approach named valuation with comparison, its basic point is to value the project or program with flexibility by means of decision tree analysis ( dta ) and stochastic dynamic programming ( sdp ), and the results are compared with that of non - flexibility, finally,
當實物期權的價值不能從項目價值中分離出來，或者影響基本資產價格的不確定性內生於期權的持有者時，此時實物期權的價值一般難以直接利用無套利方法得到，本文通過對現有文獻進行歸納，提出一種比較定價法，其基本要點是利用決策樹、動態規劃法或二叉樹模型等技術來確定嵌有柔性的項目或方案的價值，然後將其與沒有柔性的項目或方案進行比較，從而獲得各種柔性的價值，作為這種方法的一個應用，本文研究了柔性勞動合約的設計與定價問題，研究表明，對企業重要員工採用長期勞動合約，而對一般員工採用短期合約可以節約勞動力使用成本。 -
The present results indicate that the quantitative description of the non - dimensional mean lateral streak spacing + differs from the results previously published. the spacing + is not a constant value of 100. it becomes larger as the reynolds number in terms of shear velocity increase
試驗結果表明，低速帶間距的無量綱數+並非為以往一致認為的100左右的常數，而是隨摩阻雷諾數的增大而逐漸增大，在水力光滑區與摩阻雷諾數成二次方關系，在過渡區則為線性關系。 -

Result of study indicate high school student, ethnic minority of guangxi, total creativity competence relatively high at present, mean value is 98. 96, in other words the standard divides into 9 fen, but creativity level differs greatly in students, and city and student creativity of outlying district difference of competences extremely remarkable, urban students " creativity overall level is higher than students in the outlying district
研究結果表明，目前廣西少數民族高中生總體的創造力水平較高，均值為98 . 96 ，相當于標準分9分，但學生中創造力水平的差異較大，而且城市與邊遠地區的學生創造力水平的差異極為顯著，城市學生的創造力總體水平高於邊遠地區的學生。 -
We draw the conclusions as follows from prediction results : the total salinity of groundwater will slightly increase compared with present mean value, when the irrigation water amount is reduced 10 % of present normal water quantity in the 2005
從預測結果看， 2005年在引水量減少10的情況下，試區的地下水礦化度較目前多年平均值略有升高。 2010年，當引水量減少30時，地下水礦化度在不同時期有較大幅度上升，值得引起注意。 -
Hard rationing implies market imperfections, but that does not necessarily mean we have to throw away net present value as a criterion for capital budgeting
