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。

The usual plan is to put in the water first, then add the indigo and copperas, which should be dissolved first, and finally to add the milk of lime, stirring all the time. Artificial indigo has been made from coal-tar products. The raw material is a coal-tar naphtha called toluene or toluol, which is also the raw material for saccharin, a sweetening agent made from coal-tar.

通常先加水，然后添加靛蓝和已溶于水的绿矾，最后加石灰乳，不时的搅拌人造靛青是取自煤焦油的产品物，原料是所谓甲苯的煤石脑油，这也是糖精的原料，糖精是取自煤石脑油的一种甜剂。

Be mixed by copyist copyist is be sent first and concern lately, deliver the problem that always expect is less than first, late and OK study what suit us to develop most.

"In accordance with this rule, it may safely be assumed that the forefathers of Boston had built the first prison-house somewhere in the vicinity of Cornhill, almost as seasonably as they marked out the first burial-ground, on Isaac Johnson's lot,"

根据这一惯例，我们可以有把握地推断：波士顿的先民们在谷山一带的某处地方修建第一座监狱，同在艾萨克-约翰逊地段标出头一块坟地几乎是在同一时期。

In accordance with this rule, it may safely be assumed that the forefathers of Boston had built the first prison-house, somewhere in the vicinity of Cornhill, almost as seasonably as they marked out the first burial-ground, on Isaac Johnson's lot, and round about his grave, which subsequently became the nucleus of all the congregated sepulchres in the old church-yard of King's Chapel.

按照这一常规，可以万无一失地推断，波士顿的祖先们在伊萨克。约翰逊①的地段内，在他的坟墓周围划出了最早的葬地，并且几乎与此同时，还在康布尔附近一个地方建立了第一所监狱。伊萨克·约翰逊的坟墓后来成了皇家旧教堂墓地里一片坟墓的中心。

In accordance with this rule, it may safely be assumed that the forefathers of Boston had built the first prison-house somewhere in the vicinity of Cornhill, almost as seasonably as they marked out the first burial-ground, on Isaac Johnson's lot, and round about his grave, which subsequently became the nucleus of all the congregated sepulchres in the old churchyard of King's Chapel.

新殖民地的开拓者们，不管他们的头脑中起初有什么关于人类品德和幸福的美妙理想，总要在各种实际需要的草创之中，忘不了划出一片未开垦的处女地充当墓地，再则出另一片土地来修建监狱。

In accordance with this rule, it may safely be assumed that the forefathers of Boston had built the first prison-house somewhere in the vicinity of Cornhill, almost as seasonably as they marked out the first burial-ground, on Isaac Johnsons lot, and round about his grave, which subsequently became the nucleus of all the congregated sepulchres in the old churchyard of Kings Chapel.
