In terms of the topological invariant in Riemann-Cartan spacetime proposed by Prof. Duan and the φ-mapping topological current theory, we gave the cosmic strings with the complex scalar field and showed that the strings appear in the zeroes of the scalar field. Meanwhile one can find that the length of cosmic strings is quantized in the topological level and the quantum number is determined by Hopf indices and Brouwer degrees.

The change in net income was primarily attributable to a $26.9 million decrease in research and development expenses related to the cessation of the development of Sulonex in March 2008, a $5.4 million decrease in research and development expenses related to KRX-0401, a $20.8 million increase in license revenue related to an amendment to the September 2007 sublicense agreement with Japan Tobacco Inc. and Torii Pharmaceutical Co., Ltd. which eliminated the Company's significant ongoing obligations included in the original agreement ($18.0 million) and a $3.0 million milestone payment from JT/Torii earned in the first quarter of 2009, and a $3.6 million increase in other revenue primarily related to the settlement of a dispute for $3.5 million.

在净收益的变化主要是由于2008年3月，在研究和开发费用与韩国证券期货交易所，0401（perifosine五百四十〇点〇〇万美元减少到1的研究和有关的发展的Sulonex停止开发费用二千六百九十点〇〇〇万美元减少），在涉及对2007年9月与日本烟草公司和鸟药业有限公司转授权协议，消除了公司的重大，持续的义务的修正案，授权收入二千零八十零点零零零万美元增加原协议中（$ 18.0万美元），由日本烟草300万美元的里程碑付款/鸟赚了2009年第一季度，并在其他收入主要是与一个以350万美元的争端解决三六○○○○○美元增加。

The present invention relates to a method for heuristically starting up DC brushless servo electric machine, including the following steps of (1) after powerup of an increment type photoelectric encoder, electrifying a stator winding two by two with identical time interval to generate six-directional stator winding resultant magnetic fields;(2) detecting six different angles rotated by the rotor within identical tiny time interval by the photoelectric encoder;(3) selecting most positive value rotation angle from the six different angles, and determining maximum torque corresponding to the stator winding resultant magnetic field, and implementing servo startup using the maximum torque as constant starting torque;(4) after the zero-point signal of the photoelectric encoder occurring, switching to servo operation with normal constant torsion.

In fact, to obtain the SEM poles is just a problem of searching the zeroes of a transcendental function in complex plane.

我们知道，从理论上计算散射体的极点，实际上归结为在复平面上搜索一个超越函数零点问题。

In the complex plane of the actual control parameter, certain roots converge to the transition point of the model.

在实际控制参数复平面中，零点会聚于模型的相变点。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
