Contrasting with control treatment, the fit of the Exponential distribution in characterizing fine root longevity was elevated under N amendment treatment, at the same time, the distributions of Welibull, Lognormal, and Normal were still better in character. All above indicated that N fertilization treatment maybe only alter the absolute value of longevity frequency, but the ratio between longevity frequencies was the same as before. So the model of longevity was unalterable.(5) Regardless analyzed with whichever categories i.e.

对各生长季细根寿命的统计分布拟合检验的结果与对照相似，施肥仅仅提高了总体分布对细根寿命的拟合优度，但威布尔、正态以及对数正态分布仍然拟合最好，这说明施肥可能仅改变了不同细根寿命频数的绝对值，但各寿命频数间相对比例并未发生明显变化，寿命理论分布的类型保持不变。

Because the thermal properties of materials are time-depandent,it's possible to increase the accurateness of numerical simulation with the variable thermal properties.

由于材料的物性参数是随着温度时刻变化，采用变物性参数可进一步缩小模拟结果与实际间的差异。

Pitch circle diameter: d = mz = 3X12 = 36 Tooth crown heights: ha = m (f0 + x)= 3X (l +0.5)= 4.5 Tooth High: hf = m (f0 + cx)= 3X (l +0.25-0.5)= 2.25 Tooth full height: h = ha + hf = 4.5 +2.25 = 6.75 Addendum circle Chemical pumps diameter: Da = d +2 ha = 36 +2 X4.5 = 45 Fixed string tooth thickness: Sxn = m (π/ 2 * cos2a + xsin2a)= 3X (1.387 +0.6428 X0.5)= 5.125 Fixed string of high gear tooth thickness measurement: hxn = m (π/ 8 * sin2a + xsin2a)= 3X (0.7476X0.117X0.5)= 2.42 Modulus coefficient x0.5 m3 O20 ° pressure angle tooth thickness Sxn5.12 fixed string Addendum Coefficient string f1 fixed gear tooth thickness measurement most high hxn2.42 Teeth z12 2, shaft wear and tear maintenance: Axis gear pump wear is mainly because with the support roller shaft at both ends between the friction and wear, so that smaller shaft diameter.

分度圆直径：d=mz=3X12=36 齿顶高：ha=m（f0+x）=3X（l+0.5）=4.5 齿根高：hf=m（f0+c-x）=3X（l+0.25-0.5）=2.25 齿全高：h=ha+hf=4.5+2.25=6.75 齿顶圆直径：Da=d+2ha=36+2X4.5=45 固定弦齿厚：Sxn=m（π/2*cos2a+xsin2a）=3X（1.387+0.6428X0.5）=5.125 固定弦齿厚测量用齿高：hxn=m（π/8*sin2a+xsin2a）=3X（0.7476X0.117X0.5）=2.42 模数m3变位系数x0.5 齿形角o20°固定弦齿厚Sxn5.12 齿顶高系数f1固定弦齿厚测最齿高hxn2.42 齿数z12 2、轴的磨损维修：齿轮泵中轴的磨损主要是因为轴两端与支撑滚针间的摩擦磨损，使轴径变小。

On the other hand, equivariant algebraic topology concerns the study of algebraic invariants of space with group actions. It is really a study of symmetries on spaces, and has always occupied a central role in mathematics.

在另一方面，等变代数拓扑关注于带有群作用的拓扑空间代数不变量的研究，其更深刻的本质在于对空间对称性的揭示，因此从来都在数学研究中占有重要的地位。

The structure of rock is extremely complicated discontinuous and heterogeneous body, its mechanics property has non-linear, anisotropism and rheology characteristic, which changed over time.

岩石的结构是极其复杂的非连续和非均质体，其力学属性具有非线性、各向异性及随时间变化的流变特性。

Another product that INCREDIBLE had bought in recently is the backpack from Japan's Anonym Craftsman Design. With the suede in different matching color and using Dupont Teflon as the main material to make it extremely durable, the backpack also comes with many internal compartments for your laptops, books etc. Because of the material used, the backpack still maintains its shape even with heavy load in it for a long period. The backpack is also tailored for Asian's smaller frame with a large capacity but not big in size.

另外，INCREDIBLE 也由日本引进了以 Anonym Craftsman Design 的背包，这款背包把经典的outdoor款式重新设计改良，必备的麂皮底部用上了其他配色，不会变得沉闷，而使用了 Dupont Teflon 这个有名的布料，把袋子的保护性能加强，而袋子里也加了一间格是给大家放手提电脑、书本等等比较重的东西，从而令到背包底部不会因放了重件加上长时间用后而变型，还有体积和容量都是针对亚洲人的体型再加改良，容量依然很大但袋的体积却是细少些。

Someone uses blue friend to describe the rational and pure mood between men and women .It spurns crazy and ardency of sirens friend. It delivers sincere and blessing of friends . Blue lets soul arise clear ideas, Blue lets life become simple natural. You can acquire heart quiet in blue world.

有人用蓝颜知己形容男女间理性纯净的感情，它摒弃红颜的痴狂与热烈，传达友人的真诚与祝福，蓝色让心灵升起洁净的意念，蓝色让生活变得纯朴自然，在蓝色的世界里，你能收获内心的宁静！

Next morning we were eventually bundled into the back of a crowded bus. The few words of Aymara we'd picked up went down very well with our fellow passengers and the journey passed in jovial -- Spanish conversation.

第二尺早晨我们被塞进了一辆拥挤的公汽，我们间能枫起的不鸟的几个阿白拉词同同车的乘客交流，居然也相谈甚欢，旅程变的十分愉快，西班牙人的流话。

Using a method for storing the large-scale sparse matrix with varying band width, Cholesky decomposition, Green function and normalized least square fitting inversion, the paper improved the computing accuracy and efficiency in imaging calculation.

利用有限元方法实现了井间电磁成像，为了求取散射电磁场的积分方程组，运用了处理大型对称变带宽方程组的 Cholesky 分解法，反演时使用了格林函数和最小二乘法，既提高了反演速度又提高了反演质量。

This model has been applied to simulate the crack extension in three point bending creep test.

应用该模型，对三点弯曲蠕变试验中裂缝的扩展过程进行了有限元计算，发现裂缝扩展随时间的变化与应力—应变曲线的形状，尤其是强度破坏点以后的曲线形状密切相关。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
