查询词典 aft

This model can analyze the regression relation between covariate and log survival time, and its form and explanation of regression coefficient is close to the general linear regression equation, the explanation of analysis results is more simple, more direct and easier to understand than that of proportional hazard function model.

AFT模型研究协变量与对数生存时间之间的回归关系，模型的形式与对回归系数的解释与一般的线性回归方程相似，而对分析结果的解释则较比例风险回归模型简单、直观，更易于理解。

So, the evidence again point to the aft 15 cm gun of the Tsi Yuen playing a significant role - whether it was Wang and Li doing it by themselves or in conjunction with the surviving members of the gun crew.

因此，相关证据再度显示济远的15cm尾炮在这场作战中扮演显著的角色，无论操炮的是王国成与李仕茂这两名甲板水兵，或者是舰尾幸存的炮组人员。

Checking the casualty lists of the aft 15cm gun crew could also help establish how much of a role Wang and Li played in hitting the Yoshino.

如能对照济远15cm尾炮操炮人员的伤亡纪录，对於厘清王国成与李仕茂在炮打吉野时扮演的角色应该是有帮助的。

So when the gyrocar tilts sideways, the precession torque generated tilts the gyroscope in a fore-and-aft direction- not much use.

因此，当gyrocar倾斜，侧身，岁差转矩产生的倾斜，陀螺在一个前列和尾部的方向没有太大的使用。

Half-round fender to be fitted to the shell plating from forward shoulders to the aft shoulders at upper deck level and 1.50 m below upper deck. In addition, half-round fender to be fitted in way of forecastle and poop at two levels to secure that no mooring rope touch the shell. The fender to be of pipe 150 mm x 15 mm with flat bar inside. Fenders to be well supported from backside.

在船壳板的上甲板和上甲板以下 1.50m 位置处，分别安装有从艏尖突至艉尖突的半圆形护舷木，同时在艏楼和艉楼的两个位置上应安装有半圆形护舷木以确保系泊缆绳不与船壳板接触，并直径为 150mm×15mm 钢管的护舷木内部带有扁钢，以便对护舷木从背部进行很好地支撑。

The image showed that the ratio of raw material of RPC and particle distribution accorded with maximum packing density theory, and the porosity of accumulation was the least. The DSC showed the reaction rate of RPC was very fast and main hydration process focused in shorter time; SEM and X-ray showed that structure of the harden body of RPC was much denser, which mainly composed of some abnormal flat grains that got maximum packing density, and hydration products were mostly composed of Ⅲ type C-SH gel and a small amount of Ca2 and no AFt crystal.

由图象分析可知，即C原材料的比例及颗粒度符合密实堆积原理，堆积物的孔隙率达到最小；差示扫描量热分析表明，RPC的水化反应速度很快，主要的水化过程集中在较短时间内；扫描电镜及X衍射试验表明，RPC硬化体的结构非常致密，主要由一些不规则状的扁平粒子紧密堆积在一起，水化产物主要是Ⅲ型C-S-H， Ca2晶体的量稀少且没有钙矶石。

Of African oneself fore-and-aft show quite, its position in world economic system continues to be changed infirmly.

非洲自身的纵向比较显示，它在世界经济体系中的地位继续弱化。

For vessels 15 years of a ge and over, an Interim Certificate of Class can be issued only aft er losing

对于船龄大于等于15年的船舶，只有在原船级社完成对该轮提出的所有过期检验、过期遗留项

Leastsquare method and Lagrange's interpolation formula see their applicationsfor fitting fore-and-aft lines-whose aim is to calculate the intersection point ofequivalent inclined waterline-and differences. In order to replace theinconvenient alternate conduct of drawing and calculating, improvement hasbeen introduced into the paper which means all work can be done bycomputer. Capacity calculation cannot be done without boundary layer build-up. Fit every area curve and area moment curve is necessary because ofinterpolation.

在第二章中，给出了B样条函数的数学表达形式，推导了B样条曲线下所围面积、面积矩公式；讨论了最小二乘法和拉格朗日插值法的数学形式，并在拟合船体型线上给出首、尾轮廓线的具体实例，对比不同方法进行拟合的差异，其目的是为了求得与等体积倾斜水线的交点；而水线的确定改变了以往人工作图与计算交替进行的不足，尝试用计算机完全代替人工作图，以求有所改进；在舱容计算中，在至少包括舱室前、后壁的范围内拟合横剖面积、面积矩曲线，插值求得任一纵向位置处的剖面，以解决舱室边界条件。

I walked aft until I reached the mainmast.

我朝船尾走去，到主桅前边停了下来。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.
