查询词典 approximate partial derivative

The partial least-squares regression model is built up to forecast crop leaf water potential of estival maize.Thirdly, atmosphere aspect, the low water age has been forecasting by R/S method of fractal theory in Si Chuan middle region. The chaotic behavior of agriculture meteorologic factors (average temperature, max temperature, min temperature, temperature of the earths surface, evaporators, precipitation, relative humidity, sunlight time) time series is investigated using the phase-space reconstruction technique, and the delay time and relation dimension and min embedding dimension and Lyapunov exponent and Kolmogrov entropy is calculated. The atmosphere water potential is calculated by surveyed data, and the day change law of atmosphere water potential and the relation between it and sun radiation has been discussed.

第三，关于大气方面，利用分形理论中R/S分析法对川中丘陵区的枯水年进行了预测；利用混沌理论的重构相空间技术，确定了农业气象因子(旬平均气温、最高气温、最低气温、地表温度、蒸发量、降水量、相对湿度、日照时数)的延时、关联维数、最小嵌入维数、Lyapunov指数、Kolmogrov熵，从而证明了以上各农业气象因子的时间序列具有混沌特性，为利用混沌理论预测各气象因子提供了科学依据；利用田间自动气象站的数据计算了大气水势并探讨了大气水势的日变化规律以及大气水势与太阳辐射的关系。

Of the evaluable 39 patients, 32 patients (82%) obtained complete response and 5 patients (13%) had partial response.

在可以评估反应的39位病患中，完全反应者有32位(82%)，部分反应者有5位(13%)。

Of 49 patients evaluable for response, nine (18.4%) had a partial response, and 16 (32.7%) had stable disease for 6 months or longer.

其中可评价反应49例，部分反应9例（18.4％），6个月或更长的病情稳定16例（32.7％）。

Results: Twenty patients were studied. Fifteen patients were evaluable. There were no complete response. Partial response was achieved in 4 patients.

结果，共有20位病人进入此研究，只有15位可评估治疗反应，无一例完全缓解，有四位达部份缓解，缓解率达27%。

On the contrary, logic programming languages, based on Horn clause logic and resolution, allow existentially quantified variables and partial data structures but lack both deterministic evaluation and lazy evaluation.

相反，基于HORN子句逻辑和消解原理的逻辑程序设计语言允许存在量化的变量和部分数据结构但又缺少确定和懒惰求解的性质。

Functional programming languages, based on reduction, have properties such as deterministic evaluation and lazy evaluation; however they lack some desirable properties such as existentially quantified variables and partial data structures.

但同时它又缺少诸如存在量化的变量以及部分数据结构等所希望的性质。

We formalized a notion of security for partial delegation with warrant proxy signature schemes, i.e., existentially unforgeability under an adaptive chosen-message attack and an adaptive chosen-warrant attack. We compare the new model with the previous formal models and identify their weakness.

重新给出了具有证书的部分代理签名的安全定义，即适应性选择消息攻击和适应性选择授权文件攻击下的不可存在性伪造，建立了形式化安全模型。

Partial least-square regressive can give the most expositive elements to establish the forecasting model . Combined with proportion method , it can reflect the seasonal change factors causing the variation of electricity consumption , which makes the forecasting of monthly electricity consumption more accurate .

偏最小二乘方法能够提取若干对系统具有最佳解释能力的综合变量来建立预测模型，该方法与比重法结合应用于月售电量的预测之中，能更好地体现引起月售电量变化的平稳因素，季节突变因素的周期性，使得月售电量的预测更加准确。

Certainly ,if there are really more than one child in one family ,it's very hard for parents to share all of thing during them when a family is not very rich ,we should consider the living condition, if it allowed ,it's ok everyone have one ,but for a not rich fainly it's out of rich ,then ,maybe this moment the partial idea will appear in the child who do not get what he or she want .

当然，如果真的是一个家庭里不止一个孩子。当家庭不太富裕的时候，对于父母来说说真的很难让所有的孩子都一起分享所有的东西，我们应该考虑家庭调价，如果允许的话，每个人都可以拥有一个，但对于不太富裕的家庭来说，此时此刻，如果没有得到想要的东西的那个孩子，偏心的想法可能就萌生了，突然发现：哦？！
