In 14 patients with angiogenic tumors of the soft tissue ( 13 benign tumors and 1 malignant tumor) were analyzed. Results Benign hemangiomas included cavernous (n=7), intramuscular (n=2), mixed (n=1), racemosum (n=1), glomus (n=1) and angiomatosis (n=1). The vascular component within the tumor displayed iso-intensity on T1WI relative to the skeletal muscle, and hyper-intensity on T2WI. One case of hemangiopericytoma showed slightly low signal on T1WI and slightly high signal on T2WI.

结果 13例良性肿瘤中，海绵状血管瘤7例，肌肉内血管瘤2例，混合型血管瘤、蔓状血管瘤、血管球瘤、血管瘤病各1例，瘤血管成分在T1WI上呈等信号，T2WI上呈高信号，肿瘤有不等量的纤维组织和脂肪组织；血管外皮细胞瘤1例，T1WI上呈略低信号，T2WI上呈略高信号。

In APAR simulator system design scheme a new design is used to generate all the sum, azimuth difference and elevation difference channel target echo signal by passing only one channel signal of target through antenna gain multiplication circuit, which simplified the simulator design.

提出了在很短的一帧时间里用匀加速直线运动拟和目标实际运动轨迹的方法，简化了目标回波模拟系统并实现了目标数据的实时模拟。

Typical MR findings of acute apicitis include low T1 signal and high T2 signal with rim enhancement.

急性岩尖炎典型的MR表现包括T1低信号、T2高信号，并环状强化。

Colour, a kind of stable and effective visual signal which is epigamic to animals for pollination and seed-dispersal, sometimes could become aposematic signal to herbivores.

因此，向潜在的植食动物传达自己的防御信号对植物是有益的。

After sampling and avoidance learning, herbivores can discriminate this signal and associate it with unpleasant experiences, so aposematic coloration comes into being between plant-animal interaction. The theory of aposematic coloration has not been accepted in plants while it has been adequately discussed for a long time in animal kingdom until Hamilton's signal theory about autumn colours was published.

颜色作为一种稳定有效的视觉信号通常是花和果实的诱惑信号，某些情况下也是一种警戒防御信号，植食动物经过抽样学习后能识别这种防御信号并主动回避，从而形成了植物的警戒色。

In this paper, we use a computer sound card to replace the data acquisition card in the industrial, applicate LabVIEW based graphical programming language to develop a voltage signal acquisition system to collect voltage signal, the method is simple, high cost-effective.
