At last, all related problems due to ship type and towing speed influencing the quality of captured images and results were discussed. A ship model with V-shape bottom and protruding keel might cause some disadvantages for PIV measurements. The use of longer laser light ducts extending deeper is a possible solution. A ship model with light yellow paint will cause the unproportionate of light and will cause white background on captured images. It is suggested to re-paint the ship model in black or dark colors to solve this problem. In high-speed test conditions, a ship model's bow waves entrain large amount of air bubbles into water and those bubbles will block the view of camera causing some random black spots in the images. Thus, it is necessary to remove the useless black spot data and repeat the same test condition if statistics requires enough number of images.

本文讨论建立此系统之技术及实验方法，设备的架置方式和配置为一可调性调整之开放式架构，质点施放方法以一自制的施放架於实验前先布置於测试段中，并制定一实验流程规范，再分别针对实验所得滑航型及排水量型船模的流线方向及切流线方向各不同位置及船速之速度进行流场分析；实验结果发现不同船型会造成不同的实验困难：船形上突起之龙骨及V形船底会遮住照明光线，可利用较深之导管调整光页角度改善；而浅色船模表面会造成光线的不均匀，可以更改船模涂装颜色改善；高速实验的气泡会不定点的遮住光线，须先除去无资料区域并使用更多资料组数来改善。

This method can ensure to obtain all reasonable solutions meeting the fault equation, can be applied for various fault correlation criteria (such as various residual vector norm criteria) and underdetermined fault equation, and the algorithm is very simple and facile, not necessary to compile specific program for every particular condition.

From the view of the optimization methods, these methods confined to the optimization under singular-goal condition, there are no models which compressively reflect mathematics model of these goals in all-round way, so the research in this respect is feasible .necessary that having great significance too.

虽然也出现了很多综合优化模型和多目标优化，但这些模型往往只考虑工期与成本、工期与资源，质量与成本的单一关系，或者只考虑工期、成本、资源的关系，往往忽略了工程质量。

The production performance of a gas reservoir idicates that the starting pressure phenomenon occurs in gas flow just as the one occurs in liquid flow and the gas "slippage effect" seems to be contradictious to its starting pressure, therefore it is very necessary to study the generation condition and change law of the both through testing.

实际气藏的生产特征反映出气体渗流与液体一样存在启动压力现象，而气体的&滑脱效应&似乎与气体的启动压力现象相矛盾，所以极有必要通过试验来研究气体二者现象产生的条件及变化规律。

If it can be shown, firstly, that exogamous tribes exist, or have existed ; and secondly, that in rude times the relations of separate tribes are uniformly, or almost uniformly, hostile, we have found a set of circumstances in which men could get wives only by capturing them — a social condition in which capture would be the necessary preliminary to marriage . And

如果能够被证明，首先，异族结婚的部落存在，或曾经存在；第二，在野蛮时代分离的部落的关系是一律，或几乎一律敌对的，我们便发现了男人只能靠俘获她们得到妻子的一种环境——劫掠对结婚将是必要的预备的一种社会条件。

And while this state of enmity lasted, exogamous tribes never could get wives except by theft or force.If it can be shown, firstly, that exogamous tribes exist, or have existed ; and secondly, that in rude times the relations of separate tribes are uniformly, or almost uniformly, hostile, we have found a set of circumstances in which men could get wives only by capturing them — a social condition in which capture would be the necessary preliminary to marriage .

那么在一个合理数目的经良好鉴别的案例中，如果这些条件——异族结婚为部落法律，并且敌对是分离的各部落相互对待的主流关系——被证明如可预期的，伴随着一种猎妻制度，而存在或曾经存在，我们将有理由推断——没有出现不符合这种解释的现象——在劫掠体制流行的地方，或者劫略形式作为一种结婚礼仪被尊奉的地方，这些共同的条件存在于每一个案例之中。

The problem in the case is studied and deduced, and the way of solving problem can be discussed. Author think its motivation mechanism of Japanese joint venture in Shanghai needs to advance. The Japannish motivation mechanism is not suitable for the firm in China. But its ideas of task richness, duty expandedness, humanity welfare system, paying more attention to training etc will can be reference. It is necessary to use availability motivation mechanism according to condition in China. For example, the marketable salary system, impersonal appraising system and so on.

作者的结论是：在沪日资企业的激励机制亟待充实和提高，原来的以日本式激励机制为参考蓝本的方法已不适合中国的现状，但其工作丰富化、工作扩大化的方法，提供人性化的福利保障的做法，以及避免使员工感到和企业之间是&劳动力买卖&关系的想法，重视培训的初衷等都是有可取的地方，希望能够在新的激励理论的指导下，根据中国的实际情况，推出诸如市场化工资体系、客观评价体系等实用的激励方法。
