The results showed that the POD activity was higher in the sporophyll than that in the stems and leaves in which the POD activities were weak from bottom to top in native plant. For the Japanese plant, the POD activities of the stems and leaves were the same in all positions. However, the activity was slightly higher in mid-portion of a leaf than that in stems. The high enzyme activities were observed in mid-bottom stems in the half-bred plant, and the activity was higher in bottom leaf than that in mid-top leaf.

结果表明：3个裙带菜群体的POD同工酶其孢子叶活力都相对强于其它部位；日本裙带菜茎和叶的各部位POD酶活力相同，但叶中部的酶活力稍强于茎；自育裙带菜茎底部和茎中部的POD酶活力较强些，而叶底部的酶活力较叶中部和顶部的强；本地裙带菜的茎和叶由底部到顶部POD酶活力逐渐变弱。

The low/mid crossover frequency is sweepable from 60Hz to 1KHz providing an ideal frequency split between your subs and mid drivers and the mid/high crossover point is sweepable from 1KHz to 9KHz giving you enough range to effectively send an appropriate bandwidth to your mids and tweeters.

低/中交叉频率sweepable从60赫兹到1kHz时提供之间的潜艇和中司机和中/高的交叉点，是理想的频率从1kHz分裂sweepable到9KHz给你足够的范围，有效地发送一个合适的带宽和您的中频高音喇叭。

结果表明：1近11年的中国耕地生态压力指数比较大，并处于上升趋向，其主要原因是我国耕地面积持续大量的减少和人口快速的增加；2耕地压力省际差异比较大，东南和西南地区的耕地压力明显高于中部和北部地区；3直辖市和东南部地区耕地生态压力指数等级增高，北部、西北和中部的大部分地区指数等级无变化，仅中部和东北部的少数地区指数等级变小，但并不明显。

Foreign gene could destroy larvas mid-intestine, and reduce its appetite. Observation by microscope showed that the gaps between mid-intestine cells was extended in treated larvae, and the nucleus were destroyed, the gap between peritrophic membrane and mid-intestine cells was appeared, parts of peritrophic membrane was broken off from mid-intestine cells.

外源基因对舞毒蛾幼虫的杀虫机理在于破坏幼虫的中肠组织，影响幼虫的取食，使幼虫取食量减少，甚至终止取食；中肠细胞间隙增大，细胞核遭受破坏；围食膜与中肠细胞之间出现空隙，甚至脱落，围食膜不再完整；中肠组织脱落，成为一个严重变形的残架。

The sketch and specific design approaches of mid-block street crossing are generalized and three management and control modes are discussed. Based on extensive investigation and survey, the paper analysis the arriving laws in different land-use condition and the traffic characteristics of different crossing entities under different control modes. The initial characteristic, the speed and dispersion of the mobile flow are also intensive studied, as well as the effect of mid-block street crossing. Establish the linear planning models on the coordination between the signals of mid-block crossing and intersection. Finally the evaluation of the model output is carried out from time saving results, safety, economic results and social results. Set the example of Taiping north road in Nanjing, surveying the traffic situation, applying the method of signal coordination between the mid-block crossings and intersection to realize the south-to-north signal coordination design. The evaluation results show the coordination plan are more superior to the current signal plan.

本文首先阐述了行人过街物理设施的概略设计和详细设计方法，讨论了路段人行横道的三种交通管制方式的设计方法和实用条件；其次，在充分的实际调查基础上，详细分析了不同用地性质条件下的过街需求的到达特性和不同交通管制下不同过街实体的交通特性，分析了进入路段的机动车初始流特性，并对机动车在路段中的车速特征、离散性以及路段信号控制人行横道对机动车流的影响进行了研究；然后，根据以上分析的过街交通和机动车交通的交通特性，建立了路段行人过街信号与交叉口信号协调控制的线性规划模型；最后，对模型输出的协调控制方案进行了效益评价分析，从时间效益、安全性、经济效益和社会效益四个方面，定量和定性相结合地对其实施效果予以评价；以南京市太平北路路段为例，根据现状交通状况，应用行人过街信号与交叉口信号协调控制的方法，对该路段由南向北方向进行单向协调控制设计，并进行方案效益分析评价，提出了优于现状控制方案的人行过街信号与交叉口信号协调控制方案。

In the boreal summer, there are two STH ridge lines in mid-Pacific separated by the mid-Pacific trough, of which the north part (call as mid-Pacific STH ridge line) is joined with the west Pacific STH, and the south is belonged to the North America STH. The structure of them is winter pattern that the ridge axis slopes southward against height. Litter differences lie in vertical circulation structure of the steady and instantaneous mid-Pacific STH, and descent flow exists around ridge axis.

北半球夏季，中太平洋地区中高层存在双副高脊线，其中偏北的一条与西太平洋副高相连，偏南的一条系北美副高西伸脊线，其间为洋中槽；副高结构表现为冬季型，即高压脊轴随高度向南倾斜；中太平洋副高垂直环流的定常结构与瞬时结构差别不大，副高脊轴附近均有下沉气流存在。
