The transmit part adopts the phase-locked loop pattern of frequency synthesizing technology and uses the MC145152 and MC12022 chips to compose the phase-locked loop.It locks the frequency of the carrier-wave at 35MHz.The stabilization of the carrier-wave can be 4×10-5,the accuracy can be 3×10-5.The frequency modulation and the confection of the carrier-wave are realized by the capacity-changing diode V149 and the integration voltage-control oscillator MC1648 chip.The end power amplifier uses the audion 2SC1970 to make it work in the third magnifying state,it improves the efficiency of the magnifier and the power of the output reaches the design demand.

迪特·容格就是最早使用这种技术，创造跨越时间与空间的新视觉和感官新体验的一位先驱者。

Opposition is led by regional leaders in the more prosperous eastern lowlands, but it also includes respected academics such as Carlos Mesa, a former president, and Víctor Hugo Cárdenas, an intellectual of Aymaran descent who as vice-president in the 1990s introduced bilingual education.

反对方主要是由生活在更繁容的低地地区的地方领导人领导的，不过它的阵营中也包括受人尊敬的学者，如一位前任大学校长Caelos Mesa和Victor Hugo Cardenas，这位智慧的有艾玛拉血统的20世纪90年代的副校长在其在位时引进了双语教学。

In clover lands, there is decreasing soil organic matter and other nutrients, and soil physical properties are better with lower salinity due to less human disturbance. On other hand, azotobacter of legume increases the available nitrogen content in surface soil.

苜蓿地由于管理粗放，对土壤扰动少，容重较低，孔隙度和毛管孔隙度较高，盐碱度较低；每年对苜蓿的采收显著降低了苜蓿地土壤有机质和养分含量，而豆科固氮菌的存在，使表层速效氮含量较高。

To give the definition of the mass concrete and to concrete\'s cracks together with practical meanings of control ,and give a brief review on the research in the field at home and abroad, at last, methods to control temperature crack of the mass concrete from several aspects such as design measures,concrets material, construction schedules.etc are summed up; To explain the physical mechanics of the concrete and computing methods-Difference Method and Finite Element Method, and illustrate the application of their specific methods repectively;Several temperature factors that can influence the temperature stress of mass concrete baseplate are analyzed. The influence degree of temperature factor can be got through the ANSYS simulation computation the control of temperature can control the temperature stress, consequently control the temperature crack of mass concert baseplate; through the influence of the crack resistance ability of mass concrete baseplate which takes the reinforcement as a part is analyzed. By ANSYS simulation, the best suited volume ratio of reinforcement is found out, at same time the layout of reinforcement with the same volume ratio can also affect the resistance ability of mass concrete baseplate. Sum up of above analysis, anti-crack function of steel bar in early mass concrete baseplate is obvious, so it\'s necessary to consider beneficial effect of construction steel bar in research of temperature control on mass concrete baseplate.

本文先容了大体积混凝土及混凝土裂缝的基本概念，对国内外在这个领域里的研究现状作了扼要叙述，并从结构设计、混凝土材质、施工措施等方面总结了大体积混凝土温度裂缝控制的方法及防止措施；阐述了混凝土的基本物理力学性能，总结了大体积混凝土温度计算的方法——差分法和有限元法，并分别举例说明其具体应用的方法；分析了影响大体积混凝土底板温度应力的几种温度因素，利用ANSYS模拟计算，得出了每种因素的影响程度，通过分析提出了在这几种温度影响因素下如何通过控制温度以达到控制温度应力从而来控制裂缝的具体建议；针对大体积混凝土基础底板中配筋的不同对混凝土底板抗裂能力的影响不同，利用ANSYS进行模拟分析，得出底板中最合适的体积配筋率，同时分析了在相同体积配筋率下钢筋的具体布置对大体积混凝土基础底板抗裂能力的影响，分析表明，配置钢筋对混凝土结构的开裂阻止作用明显，在研究大体积混凝土温度裂缝题目时，要考虑钢筋在其中的有利作用。

But, when we are discussing this problem, In Starbucks or more "Starbucks" place, there is some taste sharp-edged, the makeup pemits fine, the genersosity of spirit is extraordinary, certainly making moves more extraordinary, clothes gorgeous and dont make open of the woman smiles or at the despise ground mouth-----they make probably the copy chief of vogue magzine, plan exhibition person, costume design teacher, domestic the first yoga gives up the founder of guest guild, they have been sheared bare-headed, cutting through trousers in Yunnan, listenning to Nico and underground velour, exhibitted in the most sophisticated science and technnlogy with the most underaround literature performed a company to appear and disapear, also ever from drive cross-country long got rid of Tibet, even once ascended the jade dragon snow mountain........

但是，当我们在讨论这个问题的时候，在星巴克或者更"星巴克"的地方，有一些眼光锐利，妆容精致，气度不凡，当然出手更不凡，衣着华丽而不张扬的女人在不屑地撇嘴或者微笑——她们有可能使时尚杂志的主编，策展人，服装设计师，国内第一家瑜伽舍宾会馆的创办人，她们曾经剪过光头，穿过云南长裤，听Nico和地下丝绒，在最尖端的科技展览和最地下的文艺演出商出没，也曾经自驾越野长驱西藏，甚至登过玉龙雪山

Slope direction, slope position and the bareness degree of rock have few influences upon soil nutrient and soil bulk density.

坡向、坡位和岩石裸露度对土壤养分和容重几乎没有影响。

I am afraid the baronet, whose name you are unwilling to mention to me, has done you some grievous wrong?

他被认为是一个蛮横无理，性情暴躁，不大能容人。他这个人在工作上高不成，低不就。
