Based on the decomposition theorem for vector space with module structure and rational canonical form of matrix, a kind of new block diagonal controllably canonical forms are inferred when the time invariant linear multivariable system is completely controllable, which the system matrix is similar to a block diagonal and has an analogy with its rational canonical form. Compare with current controllability canonical forms, this kind is easier to analyse the system constructional characteristic. The process of proof gives an effective solution method.

基于向量空间的模结构分解和矩阵的有理标准形给出了定常多输入线性系统一类新的块对角可控规范型，其中的系统矩阵相似与一个块对角矩阵，该块对角矩阵类似于矩阵的有理标准形，与现在有的可控规范型比较，更容易反映系统的结构特征，证明步骤给出了求解方法。

But in actual experimental process, the viscous force of friction has influenc in the varying degree to the measurement result when the initial velocity of the slide block is different.

在气垫导轨上做碰撞实验，最大限度地减少了摩擦阻力的影响，但在实际的实验过程中，仍发现滑块的初速度不同时，粘滞性摩擦阻力对测量结果有不同程度的影响，为此在气垫导轨上增加了电子发射装置，较好地控制滑块的初速度和测量滑块的加速度，从而减小粘滞性摩擦阻力对测量结果的影响。

Traditional examples of English food include the Sunday roast; featuring a roasted joint, usually beef, lamb or chicken, served with assorted boiled vegetables, Yorkshire pudding and gravy.

传统的英国食品有星期天烤肉，牛肉块，羊肉块或鸡肉块是最常见的主料。这些烤肉经常与各式煮熟的蔬菜，约克郡布丁和肉汤一块儿搭配。

Large cancellous and corticocancellous grafts may be obtained from the anterosuperior iliac crest and the posterior iliac crest. Small cancellous grafts may be obtained from the greater trochanter of the femur, femoral condyle, proximal tibial metaphysis, medial malleolus of the tibia, olecranon, and distal radius. At least 2 cm of subchondral bone must remain to aoid collapse of the articular surface.

大块的松质骨或皮质-松质骨复合植骨块，可取自髂前上棘或髂后棘，小块松质骨块可以取自股骨大粗隆、股骨髁、胫骨近侧干骺端、内踝、尺骨鹰嘴及桡骨远端，但至少要保留2cm的软骨下骨以防止关节面的塌陷。

The main achievements of the project are as follows: 1 the hypothesis that a decrease in seed mass causes an increase in mean dispersal distance has been tested based on the experiments of weed dispersal by wind. The experimental results partly support the hypothesis. The results will help farmers to make an optimal strategy of weed control; 2 a statistic method for inferring probabilistic distribution function of a random variable has been developed, by which probabilistic distribution functions of weed species dispersal have been determined; 3 the reproduction structure of Bromus sterilis has been studied; 4 a more complex CA model with 25 neighborhood cells were built, which can simulate spread of a weed population. This work promotes developments in both theory and application of CA models; 5 the "mean law" in weed control has been proposed. Accordingly, the algorism of patch spring may be calibrated; 6 the "patch" and "true patch" have been mathematically defined so that herbicide can be efficiently applied; 7 simulation validates that initial configurations of weed will affect dispersal of its population and strategies of controlling it, or its distribution patterns affect its dispersal progresses.

Results The wire direction was 14~37° lateral and 18~39° cephalad for C(subscript 3~7) lateral mass when the K-wires drilled starting at the point 1 mm medial to the center of the lateral mass and exited at the juncture between the transverse process and the facet. The tips of K-wires did not injure the nerve roots and vertebral arteries. The depth of these wires in the lateral mass ranged from 9.4 to 14.8 mm.
