It provided the reference to improve the anti-cracking capability of high strength and high performance concrete from the point of view of constructional technology and curing requirement.The result shows that the more the binder material or sand rate, the more serious the shrinkage cracking. In the concrete with a low water-to-binder ratio, a bit of difference in the dosage of water will result in big difference on the strength and the anti-cracking capability. The occurrence of cracking is mainly at early age (before 1 day). If the surface is plastered again after 2 hours of casting, the anti-cracking capability will nicely improved.

研究结果表明：随着胶结料总量和砂率的增大，高强高性能混凝土的收缩开裂趋于严重；在水胶比较低的情况下，用水量的稍微差别对混凝土的强度和抗裂性能都具有很大的影响；掺入粉煤灰对抗裂有所改善，但是其掺量对抗裂的影响并不是呈定向规律，而是存在着最优掺量；高强高性能混凝土的裂缝主要发生在早期(1d前)，若在浇注后2个小时再次抹面可以很好地改善其抗裂性能。

As can be seen from the literature which I have consulted, universal agreements has been reached as to the mechanism of low-temperature cracking of AC pavement (including contracting cracking cause by one substantial drop in temperature and thermal fatigue cracking). But the research on the low-temperature cracking is still immature up to now, which can justify the absence of related indices of low-temperature cracking of all AC pavement design methods.

但是，从查阅的文献可以看出，对于沥青路面产生低温开裂（包括一次性大幅降温引起的收缩开裂和温度疲劳开裂）的机理，人们的认识是一致的；但是，对于沥青路面低温开裂等问题的研究至今仍不够成熟，世界各国的沥青路面设计方法中均未引入低温开裂的有关指标就说明了这一点。

Targeting the biomass rice stalk,we use linestone as catalyst and cracking catalyse the tar which was pyrolysised from the target.We build the rice straw biomass gasification tar removal catalytic cracking process model by the least squares support vector machine model and optimize the model parameters through genetic algorithm.We also has gotten the best catalytic cracking temperature and gas residence time, making the highest rate of catalytic cracking tar.We made wood biomass as a target analysis so that we can thermally crack tar,and we can use genetic algorithms to optimize the model parameters that is based on the wood biomass gasification pyrolysis tar removal process model through the least-squares fitting method,then we got the best pyrolysis temperature and equivalence ratio,so that it is possible to make the tar content reach the minianum.Based on the least squares support vector machine model,we had established the model of the biomass sawdust Compression molding process and fit the Optimization Parameters objective function of the molding process .

以生物质稻秆为对象，采用石灰石作为催化剂对稻秆热解焦油进行催化裂解，由最小二乘支持向量机模型建立了生物质稻秆气化焦油催化裂解脱除过程的模型，并用遗传算法对模型参数进行了优化，得到了最佳的催化裂解温度和气相停留时间，使得焦油催化裂解率达到最高；以生物质木屑作为分析对象，对其进行热裂解脱焦，并依据最小二乘曲线拟合方法建立了生物质木屑气化焦油热裂解脱除过程的模型，用遗传算法对模型参数进行了优化，得到了最佳的热裂解温度和当量比，使得焦油含量达到最小。

cracking：裂化

参考资料 裂化 裂化(cracking) 一种使烃类分子分裂为几个较小分子的反应过程. 烃类分子可能在碳-碳键、碳-氢键、无机原子与碳或氢原子之间的键处分裂. 在工业裂化过程中,主要发生的是前两类分裂. 在中国,习惯上把从重质油生产汽油和柴油的过程称为裂化;

cracking：开裂

(40)开裂(Cracking)漆膜出现不连续的外观变化. 通常是由于漆膜老化而引起. 重要的形式为:微裂、细裂、小裂、深裂、龟裂、鸦爪裂. (41)微裂;发丝裂(Hair cracking)很细浅的表面裂纹且分布不规则的一种开裂形式. (42)细裂;

cracking：破裂

文档简介: 4-13 开模时或顶出时成品破裂 破裂(cracking)是成形品表面产生毛发状之裂纹,成形品会有棱角时,此部份常发生不易看出的细裂纹.裂纹是成形品的致命不良现象主要原因如下所示.

cracking：裂缝

3.如果是油漆过去已经漆过的表面,而且原来的油漆没有起皮(peeling)起泡(blistering)裂缝(cracking)等等问题的话,只要很轻的很快的用细砂纸磨一遍,直接漆面漆就可以啦,当然有问题的话,也要先修复,要上底漆.
