首先分析了交叉口车流的运行特点；然后基于可插车间隙理论和概率论方法，给出两股车流情况下次路车流通行能力的计算方法，并对主路车流车头时距服从M3分布次路车流的理论模型进行了推导；最后对整个交叉口的"冲突交通流-临界间隙法"进行了分析。

Based on the analysis of soil mechanics for a semi-track air-cushion vehicle,theoretical models for traction efficiency and total power consumption were established,and relationships between slip ratio and traction efficiency,total power consumption were examined respectively.

在分析半履带气垫车所受土壤力的基础上，建立了牵引效率和总功耗的理论模型，讨论了滑转率同牵引效率和总功耗的关系。

The dynamic characteristics of the half-tracked air-cushion vehicle are different from other conventional vehicles. Its mechanical equation includes several parameters being related to propulsion system, air-cushion system and soil condition. This system is a higher order nonlinear time-variant system with a delay.

由于半履带式气垫车的力学特性不同于以往的常规车辆，其动力学模型包含与驱动系统、垫升系统、地面条件等有关的多个参数，属于大滞后的高阶非线性时变系统。

This paper establishes a physical modle of carburettor vacuum when an engine is in cold condition and low revolutions, In cold cranking state and idle motion state a calculation about the changes of carburettor vacuum at the back of air choke and throttle valve is finished.

本文建立了在发动机冷车低速时化油器真空度的物理模型，计算了冷起动工况和怠速工况下阻风门与节气门后的真空度变化情况。

A Computer program of the hot starting and shutdown transients of a simple pressurized liquid bipropellant rocket engine is given,based upon the idea and basic equations provided by W.T.Webber etal.and mainly applying priem's combnstion model and feeding system distribution para- meter model.The hot starting and shutdown transients are calculated on 441B-Ⅲ digital computer and the elementary results arc obtained.

本文依据 W.T.Webber 等人提供的思路和基本方程，基本采用了 Priem 的燃烧模型和管路系统分布参数模型，为简单的挤压式双元液体推进剂火箭发动机热启动——关车瞬变工作过程编写了计算机程序，并在441B—Ⅲ型电子计算机上进行了计算，得出了初步的结果。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
