不能运动

However, Pro/E has a limitation in simulating chain transmission, it can simulate linear and circular motion but not curvilinear motion, so types like bicycle chain transmission can't be simulated by Pro/E

但是PROE在链传动仿真方面有重大缺陷落，不能解决链传动的曲线运动仿真，而只能进行链传动的直线和圆弧运动仿真，因此在类似于自行车传运链这类的不规则的链传动仿真将无法进行

Overtraining is defined as a fatigue syndrome which means that the normal level of performance can not recover after intensive training, Overtraining mainly occurs in endurance events and its occurrence is related to the disturber of neuroendocrine system and immune system.

过度训练是指大强度运动后，长时间不能恢复运动能力的一种疲劳症状，它的产生与神经内分泌系统、免疫系统的功能紊乱有关。

The modified expression of the broad emission-line profiles ire derived for the outflow kinematics model of the BLR driven by the radiation pressure. Taking into account the difference between the two lines HeI λ5876 and Hβ, it is shown the fact that the observed line width of HeIλ 5876 is broader than that of Hβ cannot be explained by the popular outflow BLR model evoked by W. G. Mathews. For comparison, line profiles of the gravitational infall model and orbital disk model are also calculated; the later is in good agreement with the observations Thereupon, conclusion is reached that the gravitational infall is an important process in the real BLR gas motion.

1推导了辐射压加速宽线云团径向外流，以及引力下落和转动等BLR运动学模型的谱线轮廓表达式，并考虑到光致电离计算表明的云团本身对Hβ和HeIλ5876谱线的辐射差异，用数值方法计算了它们的谱线轮廓，发现普遍流行的辐射加速气体外流模型不能解释HeIλ5876线宽大于Hβ线宽的观测事实，而引力下落模型则可以较好地解释观测，因此我们倾向于认为、径向内流运动很可能是BLR内的发射线云团真实运动的一个重要成分。

One is at low growth temperature, the origin of mound formation can be attributed to an intrinsic growth instability of a singular surface in the presence of so-called Ehrlich-Schwoebel step-edge barrier, which inhibit the downward movement of adatoms at surface step-edges. The other is at high temperature, or at low Ⅴ/Ⅲ ratio, the reason of mound formation is related to phosphorus deficiency.

其主要原因有两种，第一种是生长温度较低时，由于吸附原子受到附加的ES台阶边垒的阻碍作用，使扩散运动不能向台阶下面运动，而在台阶上面形成小丘，第二种是生长温度较高或Ⅴ/Ⅲ较低时，因生长中缺磷造成In的堆积而产生。

On the basis of the study on the mathematical model of the closed-loop location control, the analysis of contour error in the process motion control and error calculation model, according to the lack of using normal contour error model not to calculate contour error of curve in real-time, combining real-time contour error compensation control strategy and fuzzy logic theory, the fuzzy logic and real-time contour error calculation based self-discipline control strategy is proposed.

2在研究闭环位置控制数学模型、加工轮廓运动控制中的误差分析和轮廓误差计算模型的基础上，针对利用一般运动轮廓误差计算模型不能实时计算出曲线轮廓误差的不足，结合实时轮廓误差补偿控制策略和模糊逻辑理论，研究了基于模糊逻辑理论和实时误差计算的轮廓自律控制策略。

While the frequency can be as high as N when the particle motion is vertical, it cannot be lower than the Coriolis frequency f. In this limit, the particle motion is horizontal in 'inertial' circles, expressing the tendency for steady rectilinear motion with respect to a nonrotating reference frame.

虽然频率可高达为N时，粒子的运动是垂直的，它不能低于科氏频率楼在此限制，粒子议案是水平在'惯性'界，表达为稳定直线运动的趋势关于一nonrotating参照系。

The motion we observe on this spherical shell does not represent at all the true motion of the celestial bodies.

我们在这个天球上看到的运动完全不能代表天体的真实运动。

And if you can't talk while you're exercising, you're doing it too strenuously.

如果你在运动中不能讲话，说明你的运动过于强烈了。

Three protozoa (Bodo edax, Colpoda cucullus, Amoeba proteus) were isolated from soil. The porous simulation with glass bead, soil column and root box incubation experiments were made to study the association of protozoa movement with phosphorus translocation and its influencing factors. The effects of protozoa on corn growth and corn straw mineralization were also involved. The results showed that protozoa movement in glass bead column was greatly controlled by the pore sizes. Bodo edax, about 5-7 m, could pass through the pores of 28-20 11 m in diameters. Colpoda cucullus (30-60 m) could move through the pores of 155~116 m. However, no Amoebaproteus(100~150 m) was found in the effluents from all the columns. All the three protozoa made 32P redistribution in soil column.

本研究利用土壤中常见的3种原生动物(梨波豆虫Bodo edax、僧帽肾形虫Colpoda cucullus、大变形虫Amoeba proteus)，通过玻璃珠孔隙模拟、土柱及根箱培养试验，研究3种原生动物运动与磷素运移之间的关系及其影响因素，以及原生动物对玉米磷素营养的影响，同时对3种原生动物在玉米秸秆分解中的作用做了初步的探索，研究结果表明：原生动物的运动与孔隙密切相关，Bodo edax(5～7μm)能够穿过28～20μm孔隙，Colpoda cucullus (30～60μm)只能穿过155～116μm的孔隙，而Amoeba proteus(100～150μm)不能从玻璃柱中流出。
