According to arrival rate in the upstream intersection and number of cars at the beginning of period on the road, the paper investigates the evolution of the number of cars on the road and the number of passed cars of the downstream intersection. By switching the red time of upstream signal, we can control the number of passing vehicles of downstream intersection.

The protein synthesis of Ceteuisiae fermentum cell was inhibited by NCS when they were cultured in the medium with ~(35)S-Met.3. The Ceteuisiae fermentum cells treated with NCS were mostly in G1 stage during the cell cycle measurement. The amount of cells in Gl stage increased about 20% compared to the control. These data suggested that the process of protein synthesis may be inhibited or prolonged by NCS.

试验方法及所测指标如下：于产后第七天到第十四天记录日产奶量，最后计算每组平均日产奶量；每组随机抽取分娩后第七天、第十四天的奶样，测定乳糖、乳蛋白、乳脂、乳锌含量及乳体细胞数；于产后第七天，随机采取奶牛血样，测定血清中PRL含量；于发情周期的当天和第12天，随机采取血样，测定血清中雌二醇(Estradiol，E2)和孕酮(Progesterone，P)的浓度；记录奶牛的分娩情况、犊牛初生重、产后第一次发情日期、产后发情周期，并采用人工授精技术进行受精，记录第一情期受胎率，最后取平均值，作为衡量奶牛繁殖性能的指标。

System modeling involves with both functional modeling and timing modeling, which relate with computation model (eg, Data-flow-oriented vs. Control-flow-oriented, Uni-processing vs. Multi-processing), time model (eg, Continuous vs. Discreet, Time vs. Untimed, Cycle-based vs. Non-cycle-based, State-based vs. Event-driven, Branching-time vs. Linear-time, Single-rate vs. Multi-rate) and communication model (eg Shared Variable vs. Messaging Passing).

涉及系统建模与功能建模和时间建模，涉及的计算模型（例如，数据流导向与控制流为导向，统一处理与多处理），时间模型（例如，连续主场迎战Discreet公司，时间与Untimed ，周期为基础的与非周期为基础，以国家为基础与事件驱动，分枝时间与线性时间，单率与多速率）和通信模型。

The calling and copulation behaviour of Ancylis sativa Liu had a dielperiodicity.The female moths began to calling at the first day and increasedto 100% at the second day,then the percentage of calling decreasedgradually from the third day to the fifth day,only 16.7% of females showingcalling behaviour at the sixth day.The effect of environmentaltemperature on calling behaviour of Ancylis sativa Liu was studied duringadult life at 16℃,21℃,26℃ and 31℃.The result showed differenttemperature during adult life affected significantly the calling behaviour ofvirgin females.There was considerable variability in the calling patternsamong the different temperature groups,the higher the temperature was,thelater females called,the shorter the calling behaviour lasted.The copulationbehaviour of Ancylis sativa Liu can be divided into following squence:female calling,male responsing,male approaching female,hairpencil displayingand copulating.

枣粘虫求偶和交配行为研究结果表明，在光周期为14L：10D、温度为21℃下，越冬代枣粘虫雌蛾的求偶高峰期为黑暗期6.0-8.0小时，求偶活动以羽化后1-3天表现强烈，第二天求偶百分率高达100％，第4天开始，求偶百分率下降，到第6天仅为16.7％；环境温度对枣粘虫雌蛾的求偶活动有明显的影响，随着温度的下降，求偶高峰期明显提前，求偶高峰期的持续时间变长，在21、26、31℃下，求偶百分率接近或达到100％，在16℃下，仅为43％；枣粘虫的交配行为可分为雌蛾求偶、雄蛾反应、雄蛾接近雌蛾、打开味刷及交配成功等阶段；交配活动也以羽化后前3天表现强烈；第1、2代在黑暗周期中的交配高峰期比越冬代推后1-2.5小时；越冬代枣粘虫的交尾持续时间多为3-4小时，第1、2代比越冬代短；越冬代交尾前期多为2-3天，第1、2代多为1-2天，少数羽化当天便可交尾；雌雄成虫均有多次交尾习性，雄蛾最高交尾6次，平均3.3次，雌蛾最多交尾3次，平均1.5次，在田间自然条件下，大多数越冬代雌雄成虫只交尾1次，第1、2代交尾次数有所增高，第1、2代成虫交配率明显高于越冬代。
