Table 1 for different intervals (, d), and lists the corresponding value of FSI and VSI chart diagram E (71) value. (Continued on page 69) a - ■ Web - ridicule Bin Factory No. 1 Wang Hangping: finite dimensional linear space of differences with the infinite dimensional unit matrix 69 of infinite order), while BA ≠ E a note that the A ,[link widoczny dla zalogowanych], B is not invertible, since A, B are not reversible transformation. Six differences in the finite dimensional linear space, linear transformation B in the range of nuclear and space equal. That BVNB (0) a {0} iii B + B (0) a V, but in the infinite-dimensional linear space is not necessarily. Example 6: V-Factory () ∈ rFx], define Bf (x) a xf (x), then B (0) a {0}. Obviously lY, FEx] + B (O) (== FEx], because F (z = BV + B (0). Difference is the number field F A seven dimensions on the linear space linear transformation is A invariant subspace, if A exists, it is A invariant subspace. But this conclusion on the infinite dimensional linear space Q is not necessarily true. Example 7 breaking] a {Σ + Σb household, one b ∈ ' ,, J ∈ N}. We can define an appropriate operator,[link widoczny dla zalogowanych], so B] a number field F on the vector space. and let Af (x) a xf (x), - factory () ∈ Fix] 1A A - Plant ( ) a ÷ - factory (), take W-Fix], you AFIx] (== Fix], but AFix] ==) Fix] so the W-Fix] is not A the invariant subspace. 【References [I ] Department of Mathematics,[link widoczny dla zalogowanych], Peking University, Department of Algebra and Algebraic Geometry group.

[ ,],[E (T) value of the comparison can be seen from Table 1, 6 conclusions, when np changes VSI chart signals, the average time shorter than the corresponding FSI chart, indicating the effectiveness of VSI charts have larger; On the other hand, the VSI chart, when d or d is fixed, if the increased gap between d and d, the average signal time decreases, the discovery process more quickly out of control. On the contrary, the average time to signal a corresponding increase, which will in practice (, d) take (O.3, 1.3) or (O.1, 1.3) better. Furthermore, [5] proved that when the value of ≠. when the VSI chart in the average use of more multiple areas,,, corresponds to the larger E (D) values, the number of nonconforming product control charts have the same results, therefore, should take the two sampling intervals is appropriate. 【Reference】 Min-Hua Wang.
