The photosynthetic rate in July is better than September;the diurnal variation of Pn is the bimodal curve.

比较苹果在7月、9月的光合作用，发现7月的光合作用显著高于9月的光合作用，在7月叶片光合作用的日变化为双峰曲线，9月为单峰曲线。

Methods: Forty critically patients were divided into 2 groups. In each group 20 patients were included. Twenty patients were treated with PN+EN in experimental group; 20 patients were treated with standard TPN in control group. Two groups were supplied with equal nitrogen and caloricity.

将40例危重病人按就诊顺序分为2组，每组20例，试验组接受肠外+肠内营养，对照组接受全肠外营养，2组等氮等热量供给。

At the early stage of stress (2 d and 5 d), the Pn, Tr, Ci and Gs of own-root plant were significantly decreased, while Ls was significantly increased, the inhibition of photosynthesis of own-root plant was mainly caused by stomatal factor, water use efficiency was significantly elevated, resulting from lower Pn.

在NaCl胁迫下，自根苗和嫁接苗叶片和根系中酶(SOD、POD、CAT和APX)活性和抗氧化剂含量发生明显变化，或被诱导上升，或被抑制下降，但嫁接苗各指标均显著高于自根苗，而丙二醛含量显著低于自根苗，表现出较强的抗氧化能力。

At the late stage of stress (10 d), the chlorophyll degradation of own-root was accelerated, salt ion destroyed chlorophyll photosynthetic structure, the Pn, Tr and Gs of own-root plant were still significantly decreased, Ci was significantly increased, while Ls was significantly decreased, WUE was significantly decreased because the decreasing extent of Pn was more obvious than Tr, leading to a poor water use.

自根苗和嫁接苗叶片和根系中脯氨酸、可溶性糖、可溶性蛋白质含量在胁迫初期均会被诱导上升，随着胁迫时间的延长，有的持续上升，有的显著下降，但嫁接苗与自根苗相比，不论叶片还是根系中，各指标均显著高于自根苗，渗透调节能力相对较强。

Moreover, strong anisotropy is observed in the north and southcentral Tien Shan. Fast Pn velocity in the southcentral Tien Shan is nearly in NS directions, which is consistent with the SKS wave anisotropy concerning mantle flow. However, fast Pn velocity directions in the northcentral Tien Shan show a southward rotation variation. We estimate that it is probably related to the inserting of the crust of the Chu basin from the southern Kazakhstan platform to the central Tien Shan, which caused a change of stress fields and lithosphere deformation.

中天山北部和南部的各向异性也存在一定的差异，南部各向异性的快波方向为近南北方向，与SKS波的各向异性特征基本一致，反映了地幔物质的迁移方向；北部各向异性的快波方向呈向南凸出的旋转趋势，估计与哈萨克地台南缘楚河盆地地壳块体向天山挤入造成应力场的改变和岩石层变形有关。
