In the thesis, the fundamental formula of FFD method derives from the square root that is approximated by a continued fraction expansion in the one-way wave equation. Optimizations of the parameters of the finite-difference operator improve the validity of the method.

本论文用连分式近似单程波波动方程中的平方根导出FFD算法的基本公式，并对FFD算法中的有限差分算子进行了系数优化，进一步提高了计算的有效性。

With SPSS software, this paper also makes a detailed stepwise regression analysis of total oil consumption per 50 kilometers ( 2 y ) and its seven key influencing factors, including mileage ( 1 x ), the number of goods carried ( 2 x ), cargo weight ( 3 x ), loaded one-way trip mileage ( 4 x ), carrying rate ( 5 x ), whole-trip kilometers utilization rate ( 6 x ) and the age of vehicles.

通过使用SPSS，这篇论文对总耗油量（y1）及其七个重要的影响因子做了详细的逐步回归分析。这七个影响因子包括英里数（x1）、货物载运量（x2）、货物重量（x3）、满载时的单程英里数（x4）、运载速率（x5）、全程英里使用率（x6）以及运输工具的寿命。

Given the current complexity of industrial recovery of 3'-methyl-2'-butenyl 3, 3-dimethyl-pentenoate and the decomposition problems with 2-methyl-1-butene, research was conducted on a process for direct recycling of MBDP involving an ester exchange reaction of MBDP with either methanol, trimethyl orthoacetate, or solutions of methanol and trimethyl orthoacetate.

针对目前工业上回收3，3-二甲基－4-戊烯酸－3'-甲基－2'-丁烯酯工艺复杂、异戊烯大量分解问题，研究了MBDP直接返回循环使用工艺，MBDP与甲醇、原乙酸三甲酯或与甲醇原乙酸三甲酯混合溶液进行酯交换反应的回收新工艺，比较了四异丙基钛酸酯、甲醇钠、氢氧化钾用作酯交换催化剂的效果，筛选出回收MBDP&一锅煮&最佳工艺：按照n：n：n：n＝1.0：9.8：9.2：0.05物质的量比投料，74℃~78℃反应21h，MBDP转化为贲亭酸甲酯和异戊烯醇，单程转化率87.7%，用85%的磷酸中和甲醇钠，蒸出甲醇，直接用于合成贲亭酸甲酯。

Fare is 180php and then the boat fare from batangas port to puerto galera is 280 php if you purchase a one way ticket but if you get the roundtrip ticket u will have a 60 php dicount so instead of 560 php it will be just 500 php and then u will have to pay the 50 php environmental fee.

票价是180php，然后从八打雁港船票价为280加莱拉港PHP的，如果您购买单程票，但如果你获得来回机票u将有60个这样的PHP dicount而不是560的PHP将PHP和仅500那么在将要支付50 PHP的环境费用。

The application of P47 retention and drainage aid in offset papermaking could consistently improve the first pass retention, reduce the loses of fines and other chemical materials, speed up the water drainage from wire and press parts, lower the production cost and have a great potential for broad application.

使用P47助留助滤助剂抄造胶版印刷纸，能长效稳定提高网部单程留着率，减少纤维和其他化学原料的流失，加快网部和压榨部的滤水，减少生产能耗，降低生产成本，有广泛的推广应用价值。

As we can see from the models, the most important factors that pose great influence on total oil consumption by road cargo transport vehicles are mileage, cargo weight, mileage of loaded one-way trip, and kilometers utilization rate.

从上述的模型公式中可以看出，对公路货运工具总含油量影响最大的因素有：运行公里数、货物重量、满载时的单程公里数以及公里利用率。

The different set-up changes caused several lengthy turnarounds in the morning before Lewis could concentrate on a single long-distance run in the afternoon – which was punctuated by several late red-flag periods.

不同的设置导致了早晨测试中数次长停站，下午刘易斯聚焦于一次单程长距离测试——遭遇了数次红旗的阻碍。简森明天会回到赛车，继续MP4-25的设置工作。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.
