S1 is then changed to position 1. The voltage stored on C1 is inserted between the output and inverting input of the amplifier and the output of the amplifier changes by VIN to maintain the amplifier input at the input offset voltage. The output then changes from (VOS + IbiasR2) to (VIN + IbiasR2) as S1 is changed from position 2 to position 1. Amplifier bias current is supplied through R2 from the output of the amplifier or from C2 when S1 is in position 2 and position 1 respectively. R3 serves to reduce the offset at the amplifier output if the amplifier must have maximum linear range or if it is desired to DC couple the amplifier.

接着 S1 拨到位置 1，使 C1 的电压加在放大器的输出端和反相输入端之间，(由于电容端电压不能突变，所以)输出端的电压将产生大小等于 VIN 的变化，使放大器输入端维持输入失调电压，即当开关 S1 从位置 2 拨到位置 1 时，输出端电压将从(VOS + IbiasR2)变为(VIN + IbiasR2)。S1 处于位置 2 时，放大器的偏置电流是由输出端经电阻 R2 提供的，当 S1 转向位置 1 时则由 C2 提供。R3 的作用是降低输出失调电压，如果要求放大器具有最大的线性范围，或者采用直流耦合，就应该使用该电容。

Results: The main ultrastructural changes after Cd treatment included swelling or vacuolation of mitochondria, increase of myelin figures in GCT cells, and swelling of mitochondria in the endothelial cells of peritubular capillaries. The changes above were most prominent at 7~15d, and swelling of the cytoplasm and slight karyolysis were also found. The morphology of GCT cells didn't recovery to normal yet after 30d.

结果：镉注射后24h，GCT细胞内出现不同程度的线粒体肿胀和空泡化，胞质和线粒体内可见髓样结构，GCT周围毛细血管内皮细胞线粒体肿胀。7~15天后上述改变明显加重，部分GCT细胞见胞质广泛肿胀和轻度核溶解，30天后细胞形态仍未恢复正常。

This paper describes and analyzes the Kronstadt Russian Communist Party after the events occurred before and after the policy notable changes in the political, economic, cultural and other aspects of the Russian Communist Party has made on the corresponding adjustment and the reasons for the changes, but these adjustments and just change to the impact of the establishment of Soviet power is a double impact - both positive and negative and adverse impact.

本文以1921年春，俄国波罗的海舰队主要军事基地喀琅施塔得发生动乱为切入点。喀琅施塔得事件---这是苏维埃政权建设初期的重大政治事件，虽然迅速被苏维埃政府平息了，但是从19世纪20年代年到20世纪80年代的很长一段时间里史学界都把喀琅施塔得事件看做是反对俄共和苏维埃政府的一场叛乱。本文试图通过重组喀琅施塔得事件发生和发展过程，分析喀琅施塔得事件发生原因和结果。

Associated signs of kwashiorkor, which do not always occur, include hair changes (color becomes lighter, curly hair becomes straight, hair comes out easily with a gentle pull) and skin changes (dark skin may become lighter in places, skin may peel off, especially on the legs, and ulcerations may occur).

其他与浮肿型营养不良相关的症状还包括发质改变（颜色变浅；卷发变直；轻易脱发）和肤质改变（深色皮肤的某些地方变浅；皮肤，尤其是腿部表皮脱落；溃疡）。

Namely, the first, the beginning, end and length of growing season of every type of vegetation is estimated with threshold method and moving average method, and the beginning end and length of growing season of vegetation from 1982 to 1999 is fitted linearly, finally, linear trend of the beginning end and length of growing season of vegetation is analyzed. The second, phenological phase in different years and zones is estimated based on greatest changes of slope method and EOF analysis method, and the result monitored by the two methods is compared, as a result, trend of growing season change from 1982 to 1999 in different latitude zones is better acquired. The third, phenological phase of vegetation in different spatial location from 1982 to 1999 is fitted based on curve. Then, spatial difference rules of growing season of every year and average of multi-year is discussed in article. In the end, lag correlation and linear regress are used to study relation between phenological phase of different types of vegetation, different latitude zones, different spatial places and climate changes.

利用阈值法和滑动平均法逐年估测了每种植被类型的生长季的开始、结束日期及长度；对18年中植被生长季的开始、结束时间和长度进行一次线性拟合，分析了植被生长季的开始、结束日期和长度的线性变化趋势；基于最大变化斜率法和EOF分析法估计了不同年份、不同区域内植被生长季的开始、结束时间及其长度，并对这两种方法的监测结果作了比较，从而得到了较好的不同纬度区域1982～1999年植被生长季的变化趋势；基于曲线拟合了1982～1999年的不同空间位置的植被物候期，然后讨论了每年和多年平均的植被生长季的空间分异规律；最后利用时滞相关分析和线性回归研究了不同类型植被的物候期与气候变化的相互关系，不同纬度带的植被物候期与气候变化的相互关系，植被物候期与气候变化空间相互关系。
