The relationship between energy consumption and temperature often varies because of the different region, population and energy price. So some experts come up with some adjusting ways for calculating degree-day index.

能源消费与温度的关系往往因研究区域的范围、人口以及能源价格而变，因此一些学者提出了人口加权、面积加权、价格调整等度日指标的调整方法。

In doing so, we have gotten these objects:(1)built the relationship between natural vegetation pattern of china and the climate,based both on Kira-index and dry/wet index;(2)built the phenology model describing main natural vegetation types of china,based on degree-day;(3)built the drought sensitivity function for main vegetaion types of china; and (4)integrated the drought sensitivity function with the PDSI.

在执行过程中我们基本上按照项目计划书的原初设计完成了如下的工作：①采用Kira的生物热量指数与生物干湿指数相结合的思想，建立了中国自然植被的空间分布与气候因素之间的数量关系；②利用有效积温与生育期之间的关系，建立了自然植被主要类型的物候模型；③根据文献中的实测资料建立了主要农作物类型、自然植被主要类型的缺水敏感性指数；④将此缺水敏感性函数代入Palmer干旱强度指数的计算模型之中。新的干旱强度指数计算步长为周(7天)。

Based on the weather data of geographical points and the phenological data of CBW, the single sine model that forecast the occurrence date of cotton bollworm is developed. By using year's data of Shihezi area, parameter of CBW emergence of overwintering generation, first generation and second generation in the Xinjiang region is built under the different low temperature. Based on the above research, the concepts, functional development temperature threshold and functional developmental degree-day, are put forward. Using the data of different station in the Shihezi area, the model is validated

基于地理点的气象数据和棉铃虫物候数据，建立了棉铃虫发生期预测的single sine 模型，利用石河子地区多年的数据，建立了不同发育温度条件下的新疆地区越冬代、第一代和第二代棉铃虫羽化的参数库；在此基础上提出功能发育起点和功能发育日度的概念并修订了模型，利用石河子地区植保站的数据，验证了模型的可行性。

Theywere temperature sensitivity,physiological vernalization requirement,photoperiodsensitivity,intrinsic earliness and filling duration(growing degree-day),reflecting thegenetic characters of different cultivars in thermal effectiveness,vernalization,photoperiod response,minimum flowering time and filling duration.

阶段发育模型引入温度敏感性、生理春化时间、光周期敏感性、基本早熟性和灌浆持续期五个遗传参数，分别体现了不同品种小麦在热效应、春化作用、光周期反应、最早开花时间以及灌浆期长短这五个方面的遗传特性。

I clearly remember one warm 28 degree day in LA when I was driving my Mustang Fastback that didn't have power windows, power steering, power brakes, GPRS satellite navigation, air conditioning, cup holders, xenon lights, or bluetooth in-car telephone systems, etc… Yes, the brakes and steering were hard to operate and my face and back were wet with sweat but the sensation and indescribable high I got from driving the car down the highway was something you'd never experience from driving a modern sedan or sports car.

我清楚记得一个在洛城的日子，户外温度大约摄氏28度，我开著一辆揭背式野马。那辆车没有电动窗，没有动力方向盘，没有动力辅助煞车，没有GPRS卫星导航系统，没有冷气空调，没有杯座，没有氙气车灯，没有内装蓝牙电话系统…等等。煞车跟方向盘都很难控制，我的脸和背布满了汗珠，但是当我开上快速道路时，我内心兴高采烈的程度是你在现代的轿车或跑车身上完全无法体验得到的。

After the implementation of at guaranteed the same amount of fluid and fuel, the pump efficiency improve by 11.9%, saving 48 degree day.

实施以后，在保证了液量和油量不变的情况下，泵效提高了11.9%，日节电48度。
