First, the time series model of the random road roughness running by construction machinery is built up based on the measured data of the random road roughness and by means of the basic theory and method of the time series analysis. A real-time parameter estimation method of fuzzy weighted recurrence least square algorithm is represented through analyzing the conventional recurrence least square algorithm. Then, the new recurrence algorithm and the on-line tuning method of the weighted matrix are given out, and computer simulation is performed.

首先，以实测的地面随机不平度数据为依据，应用时序分析的基本理论和方法，建立了工程机械行驶地面随机不平度的时间序列模型，并在分析传统参数估计方法递推最小二乘算法的基础上，提出了模糊加权递推最小二乘算法的参数实时估计方法，给出了在此基础上的递推算法及加权矩阵的实时在线整定方法，并对其进行了计算机仿真研究。

A liquid container includes a liquid chamber, and a liquid supply chamber at least partially defined by at least one wall having a first opening, a second opening, and a third opening formed therethrough.

液体容器包括液体腔室和液体供给腔室，该液体供给腔室至少部分地由至少一个第二壁限定，所述至少一个第二壁具有贯穿所述至少一个第二壁形成的第一开口、第二开口和第三开口。

As I mentioned earlier, the yearend prices of our major investees were much higher relative to their intrinsic values than theretofore. While those prices may not yet cause nosebleeds, they are clearly vulnerable to a general market decline. A drop in their prices would not disturb us at all - it might in fact work to our eventual benefit - but it would cause at least a one-year reduction in Berkshire's net worth. We think such a reduction is almost certain in at least one of the next three years.

就像是我上次所提到的，相较于过去，我们这些被投资公司的股价已高于其实质价值，虽然目前以这种价位不会造成我们流鼻血，但难免会受到大盘波动的影响，当然股价下挫一点都不会造成我们的困扰，甚至反而对我们有利，但不可避免地可能会造成伯克希尔年度净值的减少，只要在未来的两，三年间，我们的投资组合市值平均每年减少 10%，就有可能会发生这种状况。

According to the draft, insurance institutions must satisfy certain requirements - including having at least two independent directors, having established independent asset-management departments, having their investment assets under independent, third-party custody, insurance funds under central allocation and management accounting for at least 80% of their total assets, and having a solvency adequacy ratio, at the previous year's end, at 120%.

根据意见稿，进行境外投资的保险机构须满足的条件包括：至少有2名独立董事；设立独立的资产管理部门，实行投资资产第三方独立托管；集中配置和统一管理的保险资金不低于公司总资产80％；上年末偿付能力充足率达到120％。

To say that X educates or is educating Y is to say at least that X is fostering desirable and morally unobjectionable dispositions in Y by the use of methods that are also desirable and morally unobjectionable, or at least that X is cultivating dispositions in Y by certain methods.

The dissecting of samples in group2 were difficult. The root of pulmonary artery and ascending aorta failed to be unfolded because fibrous tissue was tough, right and left fibrous trigone were too firm to be solved by hand. Cardiac muscle fibers couldn't be stripped along myofibrillar trajectory since they were prone to break because of their friability.
