风愈刮愈大，很快就由微风一变而为正式的暴风了；它的速度达到每小时四十到四十五英里，船如在海里遇到这种风，即使紧收着中桅的帆，也会象飞似的前进的，乘风破浪号在将近六点钟的时候到了港湾口，可是这时候潮势变了，因此它不能入港。

The wind rose, and from a fresh breeze it soon increasedto a regular gale; that is to say, it acquired a speed of from forty toforty-five miles an hour, before which a ship in the open sea would haverun under close-reefed topsails. Now, as it was nearly six o'clock when the"Bonadventure" reached the gulf, and as at that moment the tide turned, itwas impossible to enter.

Based on the BISQ model, we studied the elastic wave speed in two-phase porous isotropic media and its relation with Biot-flow and squirt-flow. The Green function is obtained for a point load in the two-phase porous isotropic media using the decomposition of the field potencial and the properties of Delta function. The expression and effects of squirt-flow in BISQ-Green function are discussed.

Through detailed analyzing some influencing factiors of sand liquefaction, seven parameters were selected as assessment indexes. They are earthquake magnitude, peak ground surface acceleration, standard penetration value, specific penetration resistance, relative compaction, average particle diameter, and water table. The extension assessment model has been established that was applied to assessment of sand liquefaction potential. The model had been trained by the historical data and has been assessed in virtue of sand liquefaction from the historical data by simulating, and got a excellent result. After introduction of the support vector machine theory, this paper established the assessment model of sand liquefaction based on the support vector machine, and assessed in sand liquefaction from virtue data of some fields in home and overseas with the tool Libsvm, which was programmed based on the support vector machine theory. And got a good coherency between the assessement results and the actual liquefaction.

The four reaction channels including hydroxyl-type benzaldoxime are endothermic reaction, thermodynamically non-spontaneous process, but the other four reaction channels including ion-type benzaldoxime participation are exothermic reaction and thermodynamically spontaneous process. The latter four reaction channels, which have lower reaction barriers, faster reaction velocities and bigger equilibrium constants than those of the former fours, are the chief reaction channels.

苯甲醛肟以羟基型参与反应的4个反应通道均为吸热反应和热力学非自发过程，它们均具有较高的反应势垒、较慢的反应速率和较小的平衡常数；而以离子型参与反应的四个反应通道均为放热反应和热力学自发过程，它们的反应势垒较低，反应速度较快，平衡常数也较大，故苯甲醛肟应主要以离子型参与反应。
