线性优化

The geometries of [99mTc-DADS]+ complexes are optimized by semi -empirical quantum mechanics method ZINDO/1 and many physical and chemical desc riptors are obtained. Multiple regression between this drescriptors and urine up take of 120 min post injection is done and one equation is obtained.

用分子力学、半经验量子化学方法中的ZINDO/1方法对[99mTc-DADS]+系列配合物的结构进行了优化，做了电子结构计算，得到各种物理化学参数和电性参数，并将这些参数对膀胱120 min摄取值进行多元线性回归分析，得到了回归方程。

The anticlastic curvature caused by bending is 1700 times as long as the sagittal curvature, and the incident angle error is only 2.2 μrad. The Von Mize stress on the bender is about 806 MPa. When Beryllium-Cu is selected as the material of the bender, the linear relationship between the curvature of crystal in 0.57~1.72 m and the driving forces in 8~2.67 N is obtained.

优化后晶体因压弯产生的鞍形曲率半径约为弧矢曲率半径的1700倍，造成的人射角误差为2.2μrad；压弯装置上的最大平均应力约为800MPa，并由此确定了以铍青铜作为压弯机构的材料，晶体的曲率半径为0.57~1.72m和驱动力为8~2.67N时的线性关系。

With Linear Time-Invariant modeling of phase noise and definition of"effective resistor", we analyze the critical parameters of the circuit and calculate the value of phase noise at the 1 /f~2 region. 3. A 4.2GHz VCO tuned by an accumulation-mode MOS varactor in TSMC 0.35μm SiGe BiCMOS process is obtained after debugging with the simulator SpectreRF.

以低压、低功耗、低相位噪声和较大调谐范围的设计目标对压控振荡器进行设计优化，最后得到由积累型MOS变容管调谐的压控振荡器，电源电压为1.5V，功耗约10mW，中心频率为4.2GHz，调谐范围为28%，在频率偏移量为600kHz处的相位噪声为-128dBc/Hz，与线性时不变模型下的理论推导结果非常接近。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
