On the basis of the conclusion above, the nonlinear weak controllable vectors can be obtained, which compose the second class of weak controllable matrix, by means of matrix transfermations of the first class of weak controllable matrix. Furthmore the second criterion of weak controllability, accessibility and strong accessibility, which is more standard, more succinct and more practical, is obtained. On the basis of the first criterion and the second criterion, several important problems about nonlinear controllability are discussed, which include 1 local controllability; 2 three classes of local controllable decomposition, separately by means of local coordinate changes in the neighborhood of a nonsingular point, a point on a singular surface or a designated point x〓 with a designated input u〓; 3 the character of controllability of the ith state variable x〓 in different controllable areas and their boundaries.

在第一判别定理和第二判别定理的基础上，我们分析了非线性系统受控性质中的几个重要问题，所得到的结论包括i得到了非线性系统在可平衡点附近的能控性判别定理；ii分别给出了非线性系统在非奇异点、s阶奇面以及在状态空间内给定的一点x〓和输入u〓上的三种状态分解形式以及相应的求解方法；利用系统的Ⅰ型弱能控矩阵与Ⅱ型弱能控矩阵秩相等的条件，得到了只用系统的前n个弱能控向量来判断系统的弱能控性的判别定理；iii通过引入系统状态分量的三类受控区域边界的定义及相应的求解方法，初步探讨了非线性系统各个状态分量在不同的受控区域及其边界上的受控性质。

Training when crawling, let the children get on the ground, into a prone position, his head looked up and, with his hands up the body, the parents of the baby's legs, bending gently on his belly, in your baby's face will put some dynamic, interesting toys, such as the roly-poly, singing dolls, electric vehicles, so as to enhance your baby's interest inspired him to crawl引逗at this time, parents can hand in his buttocks lightly stabbed you, or the palm of your hand resist his little feet, children will often put forward, so he had to crawl slowly; If a child is prone position, the only inhibitory effect head, upper limb strength should not put up their own bodies, chest, waist spaces should not inflate the abdomen should not from the bed, parents can be a towel on the baby's chest and abdomen, and then bring a towel, so that the infant chest, abdomen leaving the bed, body weight fell on hands and knees and repeated practice, the question of the lower leg strong muscles that can support the body weight, it has been gradually learn to crawl.

训练爬行时，先让孩子趴下，成俯卧位，把头仰起，用手把身体撑起来，家长把孩子的腿，轻轻弄弯放在他的肚子下，在孩子的面前，放些会动的、有趣的玩具，如不倒翁、会唱歌的娃娃、电动汽车等，以提高孩子的兴趣，启发、引逗他爬行，此时，家长可以用手在他的臀部轻轻捅一下，或用手掌抵住他的小脚掌，孩子常常会向前扑，于是就慢慢地爬行了；如果婴儿俯卧位时，只会把头抑起，上肢的力量不能把自己的身体撑起，胸、腰部位不能抬高，腹部不能离床时，父母可以用条毛巾放在婴儿的胸腹部，然后提起毛巾，使婴儿胸、腹部离开床面，全身重量落在手和膝上，反复练习后，待小腿的肌肉结实，能支撑身体重量时，也就渐渐地学会爬行了。

For thin polycrystalline films, especially those with columnar structure, once the diameter of grains on the film surface is larger than the film thickness, the total area of above and under basal planes (film-substrate interface) will be larger than that of side plane.

对于薄膜特别是柱状晶薄膜，当晶粒在膜平面内的尺寸大于膜厚时，柱状晶粒的上底面和下底面的面积将大于侧面的面积，因此薄膜中的晶粒生长除像整体材料中的晶粒生长一样考虑晶界能外，还需要考虑表面能和界面能，因为各向异性的表面能和界面能将导致薄膜中的异常晶粒生长和织构变化。

For thin polycrystalline films, especially those with columnar structure, once the diameter of grains on the film surface is larger than the film thickness, the total area of above and under basal planes (film-substrate interface) will be larger than that of side plane. Therefore besides the minimization of boundary energy in traditional bulk material, surface energy, interface energy would be considered due to the anisotropy of surface energy, interface energy being able to drive the grain growth and texture evolution in thin films.

First I greeted her with her when haven't met, director of the hand, so she has too much work is refused, don't pick, then I put forward to meet requirements, see if you can talk, see plays, in this case if the director that no value script, I also willingly, then we met, chat ten minutes, less than twenty minutes, this basically is determined, hit it off.

我第一次跟她打招呼时还没跟她见过面，导演手里的活儿太多了，所以她是拒绝了，不想接，后来我提出见面的要求，看看能不能谈一下，看看剧本，在这种情况下如果导演认为剧本没有价值，那我也心甘情愿了，后来我们见了面，聊了十几分钟，不到二十分钟，这事儿基本就定了，一拍即合。

Even a small scratch or a local sheet metal parts were injured, the traditional practice of baking sheet to be re-done the entire finish, to avoid the so-called chromatic aberration, but this way, the original car's high-temperature paint will lose its significance, But in the construction of a new pump with disabilities spectrum operations, do not have to worry about paint finish color, but only to repair damage to local area, and will not damage surrounding paint, but also will become the old and new exterior color is the perfect combination of the same.

即使是一个小刮痕或是局部钣件受伤，传统的钣烤的做法都要重新做过整个漆面，避免出现所谓色差问题，但是如此一来，原车的高温漆面就失去意义，但是在全新的搏士光谱施工作业中，根本不用担心漆色色差，而且只针对受损局部区域修补，并不会破坏周边漆面，又能将新旧漆色变成一致的完美结合。

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

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
