On the base of the single-diameter laser-scanned measuring technology, a double direction laser-scanned measuring system is presented. Which combinate the laser-scanned measuring technology with special optical system. In the system, the collimation semiconductor laser-scanned beam scanning two perpendiculars direct of one plane of the measured workpiece at the same time is made. The beams with the dimension information of two perpendiculars direct are processed by the scanning receive system, the high-speed photoelectric transition and electronic data process. Two measured results of the diametric directs and ellipse tolerance,etc, parameter, of the turning workpiece on the same plane are obtained by non-contact automatic measurement. The problem of non-contact measurement of two perpendiculars direct of one plane of turning workpiece is settled. It processes many peculiarities, such as high speed, high accuracy and non-contact automatic measurement, etc.

It was seen that strain 6055 generated three kinds of dextransucrases whose molecular weights were 151 kDa,142kDa and 117kDa,respectively.Among them,the former two ones were found both in supematants and cell wall,while the later was only found in the fermentation liquor.Strain DM 1-2 synthesized two kinds of dextransucrases,and their molecular weights were 183kDa and 142kDa,respectively.The former existed both in cell wall and out of cell,but the later only was located on cell surface.Strain PC 13 produced three kinds of dextransucrases,and their molecular weights were 148kDa, 138kDa and 115kDa,respectively.The former two ones were ectoenzyme while the later was linked to cell.Resembled to strain 6055,strain L4 produced two types of dextransucrases coexisting in supernatants and cell wall with molecular weights of 145 kDa and 136kDa,respectively,but the dextransucrase of 115kDa was only found in free-cells supernatants.

The basic principle is based on spherical astronomy and elementary geometry of the trajectory mapping method based on the observation of a celestial body zenith distance, then the ship is located in order to sing the next point as the center of this satellite zenith distance of the ship's position as the radius of the circle, observing the same two objects, or objects at different times of the two observations, we can get two ship's position round, then the ship must have been a point of intersection of two ship's position on the circle.

其基本原理是建立在球面天文学和初等几何中的轨迹作图法基础上的，观测一个天体的天顶距，则航船就位于以星下点为圆心，此星天顶距为半径的船位圆上，观测两个天体或者不同时间同一天体的两个观测值，就可以得到两个船位圆，则航船一定在两个船位圆的一个交点上。

I got on Board the Ship, as before, and prepar'd a second Raft, and having had Experience of the first, I neither made this so unwieldy, nor loaded it so hard, but yet I brought away several Things very useful to me; as first, in the Carpenter's Stores I found two or three Bags full of Nails and Spikes, a great Skrew-Jack, a Dozen or two of Hatchets, and above all, that most useful Thing call'd a Grindstone; all these I secur'd together, with several Things belonging to the Gunner, particularly two or three Iron Crows, and two Barrels of Musquet Bullets, seven Musquets, and another fowling Piece, with some small Quantity of Powder more; a large Bag full of small Shot, and a great Roll of Sheet Lead: But this last was so heavy, I could not hoise it up to get it over the Ship's Side.
