Under normal temperature.the Ca2+-ATPase activity was found on the innerside of the PM.on the vacuole envelope and the chloroplast envelope,and theenzyme activity declined upon heat stress.The Ca2+-ATPase activity on the vacuoleenvelope,PM.and the chloroplast envelope in both Ca2+-and oxalate-treated peppermesophyll cells was higher than that in the control under the same condition.TheCa2+-ATPase was also found at the granum lamella,and it was activatedsignificantly by exogenous Ca2+ and oxalate treatments.Under heat stress.the Ca2+-ATPase activity declined slowly in both Ca2+- and oxalate-treated mesophyll cells.But La3+ treatment inhibited the enzyme activity under both normal condition andheat stress.

In the past, the high frequency resonance technique is usually applied in the envelope detection for a vibration signal with amplitude modulation. When applying the Hilbert transform in the high frequency resonance technique for the envelope detection of vibration signals, the computing burden is very high. On the other hand, when applying the linear least squares analysis method, the computing burden is lower. When applying the envelope detection in the lowest vibration mode, an accelerometer with the low-pass filtering cutoff frequency at 4kHz should be choose.

The LMD algorithm uses extrema to define the local mean and envelope, then to smooth the mean and envelope. To decrease errors in the smoothing process by using moving averaging, a new local mean and envelope definition method (the spline-based LMD) is proposed. The upper envelope and the lower envelope are obtained by connecting the local maxima and the local minima using a cubic spline line. The local mean is defined as a mean of the upper envelope and the lower envelope. A nonlinear simulation signal and a practical vibration signal are decomposed by the LMD and the spline-based LMD.

Afterwards, the X-35C began a series of envelope-expansion flights and on 25 January 2001, the X-35C completed tanker qualification trials with a series of air-to-air refuelings behind an U.S. Air Force KC-10.
