In a characteristically rash move, we have expanded World Headquarters by 252 square feet (17%), coincidental with the signing of a new five-year lease at 1440 Kiewit Plaza. The five people who work here with me - Joan Atherton, Mike Goldberg , Gladys Kaiser, Verne McKenzie and Bill Scott - outproduce corporate groups many times their number. A compact organization lets all of us spend our time managing the business rather than managing each other.

Through Hilbert transform, a signal's plane trace can be get. There are two frequencies in the tested signal, so the signal's plane trace may be looked as the track of the out pole's end when two poles rotate around parallel axles. Using the knowledge of motion synthesis in theory mechanics, a formula to describing the change of plane trace's step length and angle for two-frequency be get. So we may prolongate the tested signal's plane trace from the echo's initial arriving moment, and get a certain length of the signal's prolongation.

通过Hilbert变换可得到测试信号的平面迹线，测试信号中只含有两个频率成分，视为双频信号，双频信号的平面迹线相当于两连杆绕平行轴转动时外杆杆端迹线，利用理论力学中运动合成和瞬心知识，推导出双频信号平面迹线步长平方满足余弦线性复合函数，而迹线转角可视为线性变化，据此可对回波到来之前的测试信号平面迹线作延长，得到一定长度的信号延展段，信号延展段与实测段作差可得到一次、二次回波的第一个波峰值。

To the secondinstar larvae, by dropping on the pronotum and toxicant membrane, the LD50 was 0.015μg/larva and 1.41g/cm^2 at 96h after treatment, respectively. From the second instar, silkworms were fed continuously on mulberry leaves immersed of triazophos solution of different concentration, the LC50 at 24 HAT, 48 HAT, and at the beginning of the third, fourth and fifth instar was 2.38, 1.54, 0.97, 0.74 and 0.53mg/L, respectively.

结果表明，采用点滴法与药膜法，25℃条件下药剂处理后96h，三唑磷对家蚕2龄幼虫的接触LD50值分别为0.015μg/头与1.41μg/平方公分。2龄起蚕开始，于25℃条件下用三唑磷处理的桑叶饲养，在药剂处理后24、48h以及3龄起、4龄起、5龄起，三唑磷对家蚕的LC50值分别为2.38、1.54、0.97、0.74、0.53mg/L。

Methods Pterygial samples were extracted and collected and the pterygial endothelial cells and pterygial fibroblasts were cultured alone, conditional and co-cultured to form different culture systems. The methods included that to select the suitable intensity of ultraviolet by MIT, to detect the changes of curves of growth about two kinds of cells by MIT and to explore the developments of protein and RNA of vascular endothelial growth factor and fibroblast growth factor-basic in three culture systems under ultraviolet whose intensity is 20 mJ/cm^2 by ELISA and RT-PCR.
